Frequently Asked Questions - PR 500 Li 48 ALPINA

How to start the ALPINA PR 500 Li 48 saw?

Insert the battery, press the safety button (blue light), then simultaneously activate the throttle lock lever and the throttle lever. Make sure the chain brake is disengaged.

What to do if the chain does not turn despite activating the levers?

Check that the battery is correctly inserted and charged. Verify chain tension: if too tight, loosen it slightly. Also inspect the guide bar and chain for any blockage.

How to adjust the chain tension?

Loosen the housing nut, then turn the tensioner adjusting screw until the chain is tight. Grasp the chain at the middle of the guide; the drive links should not come out of the groove. Retighten the nut.

What oil to use for chain lubrication?

Use only specific chain saw oil or adhesive oil. Never use used or unsuitable oil, as it would damage the pump and reduce safety.

How to engage and disengage the chain brake?

The brake engages by pushing the front hand guard forward (towards the guide). To disengage, pull the guard back until you hear a click. Test it regularly before each use.

Why is the chain overheating and smoking?

Possible causes: excessive chain tension, empty oil reservoir, or poor oil quality. Check oil level, adjust tension, and use appropriate oil.

How to maintain the saw battery?

Recharge the battery only with the supplied charger, in a temperature range of 0°C to 45°C. Store it in a cool, dry place. If not used for a long time, recharge it every two months.

What protective equipment is recommended?

Always wear safety glasses, a noise-reducing helmet, resistant gloves, non-slip shoes, and cut-resistant pants. For pruning at height, use a harness and lanyard.

How to clean the saw after use?

Remove the battery. Clean the machine with a damp cloth and mild detergent. Remove sawdust and oil residue from the chain and guide. Never use a water jet on the motor.

What to do in case of kickback?

Kickback can be avoided by holding the saw firmly with both hands, not cutting with the nose of the guide, and keeping the chain sharp. If kickback occurs, the chain brake activates automatically. Stop the machine and inspect it.

2. SAFETY REGULATIONS

2.1 GENERAL POWER TOOL SAFETY WARNINGS

WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your battery-operated (cordless) power tool.

1) Work area safety

a) Keep work area clean and well lit. Dirty or cluttered areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders at a safe distance while operating a power tool. Distractions can cause you to lose control.

2) Electrical safety

a) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, cookers and refridgerators.
There is an increased risk of electric shock if your body is earthed or grounded.
b) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of negligence while operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the tool is switched OFF before fitting the battery, picking up or carrying the power tool. Carrying power tools with your

finger on the switch or fitting the battery with the tool switched ON invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not lose your balance. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

g) If any devices are to be connected to dust extractor and collection units, check they are connected and used appropriately. The use of these devices may reduce dust related risks.

4) Power tool use and care

a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
c) Remove the accumulator from its housing before making any adjustments, changing attachments or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
e) Maintain power tools with care. Check for misalignment or obstruction of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to become jammed and are easier to control.
g) Use the power tool and its accessories according to the instructions provided, taking into account the working conditions and the type of work to

be performed. Using a power tool for operations different to those specified may cause hazardous situations.

5) Use and precautions to take during use of battery-operated power tools

a) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with

another type of battery pack.

b) Use power tools only with specifically designated battery packs. Use of other battery packs may create a risk of injury or fire.

c) When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

d) Under abusive conditions, liquid may leak from the battery: avoid all contact. If contact accidentally occurs, flush with water immediately. If the liquid comes into contact with the eyes, seek medical assistance immediately. Liquids leaking from the battery terminals may cause irritation or burns.

6) Service

a) Have your power tool serviced by a qualified repair person using only original replacement parts. This will ensure that the safety of the power tool is maintained.

2.2 SPECIFIC SAFETY RULES FOR CHAINSAWS AND ELECTRIC CHAINSAWS.

• Keep all body parts at a distance from the toothed chain when the chainsaw is running. Before starting the chainsaw, check that the toothed chain is not in contact with anything.
  Lack of concentration when using the chainsaw can cause clothes or body parts to get caught up in the toothed chain.
• The right hand must always hold the rear grip and the left hand the front grip.
  You should never turn your hands when holding the chainsaw, as this increases the risk of accidents on yourself.
• Hold the power tool by insulated gripping surfaces only, because the

toothed chain may come in contact with hidden wiring. Toothed chain contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

• Always wear safety goggles and ear protection. Other protective equipment for the head, hands and feet is also recommended. The wearing of protective clothing will reduce accidents caused by hurled workpieces and accidental contact with the toothed chain.
• Keep proper footing and balance at all times, and only use the chainsaw on fixed, secure and flat surfaces. Slippery or unstable surfaces such as ladders, can cause loss of balance or control of the chainsaw.
• When cutting a branch that is under tension, be alert for spring back. When the tension of the wood fibres is released, the branch can spring back and injure the operator and/or kick the chainsaw out of control.
• Use extreme caution when cutting small size brush and saplings.

The slender material may catch in the chainsaw and be whipped towards you and/or pull you off balance.

• Carry the chainsaw by the front grip when it is switched off and keep it away from your body. When storing or transporting a chainsaw always use the guide bar cover. Correct handling of the chainsaw will reduce the probability of unintended contact with the moving chain.
• Follow the instructions concerning lubrication, chain tension and replacement parts. Chains with incorrect tension and lubrication can break and increase the risk of kickback.
• Keep handles dry, clean and free from oil and grease. Greasy and oily handles are slippery and can cause loss of control.
• Use the chainsaw to cut wood only. Do not use the chainsaw for purposes for which it is not intended. For example: do not use an chainsaw for cutting plastic, masonry or other non-wood materials. Using the chainsaw for operations other than those intended could result in a hazardous situation.
• Prolonged exposure to vibrations can cause injuries and neurovascular disorders (also called "Raynaud's syndrome" or "white finger"), especially to people suffering from circulation disorders. The symptoms can appear in the hands, wrists and fingers and are shown through loss of sensitivity, torpor, itching, pain and discolouring of or structural changes to the skin. These effects can be worsened by low ambient

temperatures and/or by gripping the hand grips excessively tightly. If the symptoms occur, the length of time the machine is used must be reduced and a doctor consulted.

- It is recommended that those operating chainsaws for trimming and performing height work aided by a rope and belt harness:

• should never work alone;
  – should be assisted by an operator on the ground who has received training on appropriate emergency procedures;
  – should have received training on secure climbing and work positions for this type of job;
  – are supplied with belt harnesses, ropes, flat belts with end loops, clasp clips and other recommended additional safety equipment or any other system that prevents the operator and chainsaw from falling.

• Perform cleaning and maintenance before storing the machine after use.

• Improper maintenance, use of non-compliant spare parts or modification of the safety devices can cause damage to the device and cause serious injury to the user.

2.3 CAUSES OF KICKBACK AND OPERATOR PROTECTION

Kickback can occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the chain in the cut.

Contact of the tip can, in certain cases, cause a sudden fast reverse action, pushing the guide bar upwards and backwards towards the operator.

Pinching of the chain along the top of the guide bar can rapidly push the chain back towards the operator.

Both the above reactions may cause loss of control of the saw, which could result in serious injury for operators. Do not rely exclusively on the chainsaw built-in safety devices

Chainsaw users should take additional precautions to eliminate accident or injury risks during cutting operations. Kickback is the result of poor use of the tool and/or incorrect operating procedures or conditions and can be avoided by taking the specific precautions provided below:

- Hold the saw firmly with both hands, with the thumbs and fingers around the chainsaw grips, and position your body and arms so that you can resist the force of a kickback. Kickback can be controlled by the operator if all appropriate precautions have been taken. Do not allow the chainsaw to start.

• Do not fully extend the arms and do not saw above shoulder height. This helps avoid undesired contact with the ends and allows for more control over the chainsaw in unexpected situations.
• Only use the guide bar and chains recommended by the manufacturer.

Unsuitable guides and chains can cause the chain to break and/or kickbacks.

- Follow the manufacturer's instructions regarding sharpening and maintenance of the chainsaw. A decrease in the level of depth can cause an increase in kickbacks.

- Techniques for using the electric chainsaw (battery-operated)

Always observe the safety regulations and use the most suitable cutting techniques according to the work to be performed, following the instructions and examples in the user instructions.

- Safe carrying of the electric chainsaw (battery-operated)

Whenever the machine is to be handled or transported you must:

– turn off the motor, wait for the chain to stop and unplug the machine from the mains;
- apply the protection bar cover;
– only hold the machine using the handles and position the bar in the opposite direction to that used during operation;

When using a vehicle to transport the machine, position it so that it can cause no danger to persons and fasten it firmly in place.

- Recommendations for first-time users

Before felling or delimbing for the first time, make sure:

– to have been specifically trained to use this type of equipment;
– to have carefully read the safety regulations and user instructions contained in this manual;
– you practise first on logs on the ground or attached to trestles, in order to get familiar with the machine and the most suitable cutting techniques.

- Handling and correct use of battery-operated power tools

a) Make sure that the machine is switched off before inserting the battery. Inserting a battery in an electric device which is switched on can cause accidents.

b) Charge battery packs only with the chargers recommended by the manufacturer. Battery chargers are generally specific for each battery type; use with other types can cause fire risks.

c) Use only batteries specifically designed for your power tool. The use of other batteries may cause injuries and fire risks.
d) Keep all unused batteries at a distance from paper clips, coins, keys, nails, screws or other small metal objects as contact with the same can cause short circuits. Short circuits between battery contacts can lead to explosion or fires.
e) Batteries in poor condition can cause liquids to leak. Avoid contact with the liquid. In the case of accidental contact flush with water. If the liquid comes into contact with the eyes, also seek medical advice. Liquid leaking from the battery may cause skin irritation or burns.
f) Check that the accumulator is in good condition and there are no signs of damage. Do not use the device with a damaged or worn accumulator.

2.4 PROTECTING THE ENVIRONMENT

Safeguarding the environment must be a relevant and priority aspect of machine use, of benefit to the community and the environment we live in.

• Avoid being a disturbance to the neighbourhood. Use this machine at reasonable times of the day only (not early morning or late evening when the noise could cause disturbance).
• A certain amount of chain lubricating oil is released into the environment when the machine is running, so only use biodegradable oils made specifically for this use. Use of a mineral oil or motor oil causes serious damage to the environment.
• Comply with local regulations for the disposal of packaging, deteriorated parts or any elements with a strong environmental impact; this waste must not be disposed of as normal waste, it must be separated and taken to specified waste disposal centres where the material will be recycled.
• Comply with local regulations for the disposal of waste materials
• When the machine is withdrawn from service, do not dispose of it in the environment, but take it to a waste disposal facility in accordance with the local regulations in force.

Do not throw electrical equipment away with domestic waste. According to the European Directive 2012/19/EU on electrical and electronic equipment waste and its implementation in compliance with national standards, old electrical equipment must be collected separately, for eco-compatible recycling. If electrical equipment is disposed of in landfills or in the ground,

hazardous substances can leak into the groundwater and contaminate the food chain, damaging your health and well-being. For further information on the disposal of this product, contact your dealer or a domestic waste collection service.

Li-ion

At the end of their working life, dispose of batteries paying due attention to the environment. Batteries contain material classified as hazardous for you and the environment. They must be removed and disposed of separately at a facility that accepts lithium-ion batteries.

Separate waste collection of the products and packaging used allows the materials to be recycled and reused. Reuse of recycled materials help to prevent environmental pollution and reduces the demand for raw materials.

3. GETTING TO KNOW THE MACHINE

3.1 DESCRIPTION OF THE MACHINE AND PLANNED USE

This machine is a forestry tool and precisely a battery powered chainsaw designed for trimming and pruning work performed directly on the tree.

The machine is essentially composed of a battery powered motor and a guide bar that takes the power from the battery to the motor which drives the cutting chain.

The operator is able to operate the machine with two hands, using the front and rear hand grips, and can use the main controls, always remaining at a safe distance from the cutting means.

3.1.1 Intended use

This special type of chainsaw has been designed specifically for the trimming of trees and must only be used by a trained operator following carefully planned and secure work instructions. This chainsaw is only destined to the trimming of trees when the above-mentioned conditions are complied with. It is generally conceived for use with two hands, just like a standard chainsaw. Some national regulations can restrict use of the machine.

This machine was designed and manufactured for:

– trimming and cutting of tall tree tops;
– cutting hedges, trunks or wooden beams, the diameter of which depends on the length of the guide bar;
-cutting wood only
– use by one operator only;
– use by qualified operators who have received specific training on tree maintenance.

3.1.2 Improper use

Any other usage not in keeping with the above-mentioned ones may be hazardous and harm persons and/or damage things. Examples of improper use may include, but are not limited to:

• trimming hedges;
  – carving operations;
  – sectioning pallets, crates and various packing materials;
  – sectioning furniture or other materials with nails, screws or other metal components;
  – butchering meat;
  – using the machine to cut materials other than wood (plastic materials, building materials);
  – using the machine to lift, move or split objects;
  – using the machine while fastened to fixed supports;
  – using cutting means other than those found in the "Technical Data" table. Serious injury and wound hazard.
  – using of the machine by more than one person.

IMPORTANT Improper use of the machine will invalidate the warranty, relieve the Manufacturer from all liability, and the user will consequently be liable for all and any damage or injury to himself or others.

6.1.3 Checking the chain tension

⚠ Perform all operations with the motor off.

Always wear heavy duty work gloves.

Check the chain tension. The tension is correct when the drive links do not slip out of the chain guides if you hold the chain in the middle of the bar (Fig. 10).

To adjust the chain tension:

1. loosen the cover nut, using the supplied wrench;
2. turn the chain tension adjuster screw (Fig. 9.A) to achieve the desired tension;

1. raise the bar and tighten the guard nut securely using the wrench supplied (Fig. 11.A).

⚠️ Never work with the chain loose, as it can be hazardous if the chain slips out of the bar guides.

IMPORTANT During the first period of use (or after replacing the chain) it must be checked more frequently due to settling of the chain.

6.2 SAFETY CHECKS

Run the following safety checks and check that the results correspond to those outlined on the tables.

When the chain has stopped, release the throttle trigger lever and disengage the chain brake (par. 5.4).

⚠️ If any of the results fail to match the instructions provided in the tables, do not use the machine! Contact a service centre to have it checked and repaired if necessary.

6.3 PREPARING TO USE THE CHAINSAW ON THE TREE

The chainsaw must be equipped with a flat strap with end slots suitable for attaching it to the operator's belt harness.

1. Fasten the flat strap with end loops to the fastening point (Fig. 14.A) on the rear of the chainsaw.
2. Provide suitable clasp clips to allow both indirect (via the flat strap with end slots) and direct (on the chainsaw fastening point) fastening of the chainsaw to the operator's belt harness.
3. Make sure that the electrical circuit is switched off (Lights off) (Fig. 12.B).
4. Make sure the chain brake is engaged (par. 5.4).
5. Pass the machine to the operator situated on the tree.

⚠️ Check that the chainsaw is connected securely when passed to the operator in the tree and check that it is fastened to the belt harness before releasing it from the equipment used to lift it.

1. Fasten the chainsaw to the fastening point on the operator's harness (Fig. 16). The fastening points can be central points (front or rear) or side points: - where possible, connect the chainsaw to the rear central point (Fig. 15.A) to prevent it from interfering with the climbing ropes and ensure that the weight is supported by the operator's back (Fig. 17).

NOTE The possibility of fastening the chainsaw directly to the belt harness reduces the risk of damaging the equipment whilst moving around the tree.

The chainsaw must always be switched off when it is directly fastened to the belt harness.

IMPORTANT When moving the chainsaw from one fastening point to another, make sure the machine is fastened to a new position before unfastening from the previous fastening point.

6.4 START-UP

1. Remove the bar cover guard (fig. 1.K) and the spiked bumper guard (fig. 1.J) (if fitted).
2. Make sure the bar and the chain are not touching the ground or any other object.
3. Fit the battery inside its housing correctly (par. 7.2.3).
4. Press the safety button (blue light) (fig. 12.A).
5. Press the throttle lock lever (fig. 13.B) and throttle trigger lever. (fig. 13.A).

6.5 WORKING

Before felling or delimbing for the first time, make sure:

– to have been specifically trained to use this type of equipment;
– to have carefully read the safety regulations and user instructions contained in this manual;
– you practise first on logs on the ground or attached to trestles, in order to get familiar with the machine and the most suitable cutting techniques.

To use the machine proceed as follows:

• Always disengage the chain brake, pulling the lever towards you before using the throttle.
- The machine must always be firmly held in both hands, with the left hand on the front hand grip and the right hand on the rear hand grip, even if the operator is left-handed.

Stop the machine immediately e chain stops during sawing.

NOTE During use, the battery is protected against total drainage with a protective device that switches off the machine and stops it from working.

6.5.1

Checks to be conducted whilst working

6.5.1.a Checking the chain tension

The chain tends to stretch gradually as you work, so you need to check its tension frequently (par. 6.1.3).

6.5.1.b Checking the oil delivery

IMPORTANT Never use the machine without lubrication!

Make sure the bar and the chain are face when you check the oil delivery.

Start the motor (par. 6.4) and check if the chain oil is spread as shown in (fig. 18).

6.6

FORESTRY WORK

6.6.1 Delimbing a tree

Make sure there is nothing or nobody the area where the branches will fall.

For pruning high up using a rope a belt harness, carefully follow instructions under par. 6.7.

1. Stand opposite the branch you want to cut.

2. Start cutting lower branches followed by the higher ones.

3. Make first cut from the bottom towards the top (Fig. 19.A). Complete delimbing by cutting from top to bottom, as shown in (Fig. 19.B).

6.6.2 Felling a tree

IMPORTANT Where two or more persons are working together on felling and bucking operations, such operations must be performed in separate areas at a distance from each other of at least 2.5 times the height of the tree being felled. Do not fell trees if this involves risks of injuring people, coming into contact with a power line or causing any form of damage. If the tree should come into contact with a main power line, report the incident immediately to the network provider.

Before commencing the felling operations:
– it is necessary to evaluate the natural inclination of the tree, the part where the branches are larger and the wind direction, to assess how the tree will actually fall;
– remove any dirt, stones, pieces of bark, nails, metal staples and wire;
– clear the area around the tree and find a stable place to stand;
- plan obstacle-free escape routes at a 45^ angle back and away from the direction of the fall (Fig. 20) which allow the operator to escape to a safe zone, about 2.5 times the height of the tree being felled;
- Stand uphill of the land onto which the tree will probably roll or fall over after felling.

• Performing a face notch

1. Stand to the right of the tree, behind the chainsaw.
2. Saw a horizontal face notch to 1/3 of the diameter of the tree, perpendicular to the direction in which it will fall (Fig. 21.A).

- Felling back cut

1. Perform the felling back cut at least 5 cm higher than the horizontal face notch (Fig. 22.B).

2. Perform the felling back cut leaving sufficient wood to act as a "hinge" (Fig. 22.C). The hinge wood will prevent the tree from twisting and falling in the wrong direction. Do not cut through the hinge.

3. Reduce the thickness of this hinge without pulling out the bar, until the tree falls.

4. If there is any risk of the tree not falling in the desired direction, or that it might lose its balance moving backwards and bending the toothed chain, stop cutting

before completing the felling back cut and use some wooden, plastic or aluminium wedges (Fig. 23.D) to open the cut. Force the tree to fall along the desired line by hitting the wedges with a sledge hammer.

1. When the tree starts to fall, it is necessary to withdraw the machine from the cut, switch it off (par. 6.9), lie it on the ground and take the foreseen exit route. Beware of falling branches and pay attention where you put your feet.

6.6.3 Limbing tree branches

Limbing means removing the branches from a felled tree.

⚠️ Be careful of where the branches are lying on the ground, the risk of them being under tension, the direction the branch may go during cutting and the risk of the tree being unstable after the branch has been cut.

When limbing, it is necessary to leave the lower, larger branches to support the trunk on the ground. Remove the small branches with a single cut (Fig. 24.A).

It is recommended to cut the tensioned branches working from the bottom upwards to prevent the chainsaw from bending (Fig. 24.B).

6.6.4 Bucking the trunk

Bucking means sawing a tree trunk into logs.

It is essential to make sure your feet are positioned firmly on the ground, and your weight is distributed equally on both feet. If possible, it is recommended to raise and support the trunk using branches, logs or blocks of wood.

It is easier to saw a log using the spiked bumper (Fig. 1.I):

1. plant the spiked bumper into the log and use it as a pivot. Cut with an arched motion to make the bar penetrate the wood (Fig. 25);
2. repeat several times if necessary, changing the point where you plant the spiked bumper.

- Trunk lying on the ground

When the entire trunk is lying on the ground, it is bucked from the top down (overbucking) (Fig. 26.A).

– Cut up to half the diameter, roll the log over and finish sawing on the other side.

- Trunk resting on one end only

When the trunk is resting on one end only:

– saw through 1/3 of the diameter from the bottom up (underbucking) (Fig. 27.A);
– then perform the final cut, overbucking to reach the first cut (Fig. 27.B).

- Trunk resting on both ends

When the trunk is resting on both ends:

– saw through 1/3 of the diameter from the top down (overbucking) (Fig. 28.A);
– then perform the final cut, underbucking the lower 2/3 to reach the first cut (Fig.. 28.B).

- Sloping trunk

Always stand uphill when bucking a sloping trunk (Fig. 29).

During the operation, to maintain control when the cut is almost complete, reduce the bucking pressure without removing removing your hands from the machine hand grips. Take all necessary precautions to prevent the machine from coming into contact with the ground.

6.7 FOR PRUNING HIGH UP USING A ROPE AND A BELT HARNESS

IMPORTANT This chapter describes the work procedures implemented to reduce the risk of injuries when using chainsaws for trimming and performing height work aided by a rope and belt harness. This is not intended to replace formal training on the subject. The guidelines provided in this appendix are only examples of best practice. National laws and regulations must always be observed.

6.7.1 Using the chainsaw with two hands

Using the chainsaw with two hands allows you to: - maintain a firmer grip on the chainsaw in the event of a kickback; - maintain a level of control over the chainsaw that decreases the probability of it coming into contact with the ropes and the operator's body; - adopt a safe work position to avoid any loss of control that could lead to contact with the chainsaw (unintentional movement while the chainsaw is running).

In order to be able to grip the chainsaw with both hands, as a general rule, the operator must always try to maintain a safe position when using the chainsaw:

– at a hip level when cutting horizontally or
– at a solar plexus level when cutting vertically.

• When the operator is working close to vertical trunks, with reduced lateral force on the working position, stable support is sufficient to maintain a safe working position.
• When the operator moves away from the trunk, the lateral forces increase and it is necessary to eliminate or offset them using one of the following methods:

– add an additional fastening point for the main rope to stabilise it;

– use a flat strap with end slots adjustable from the harness fastened to an additional fastening point (Fig. 30);

- Use of a temporary foot stirrup, created by a ring belt, can make it easier to achieve a stable working position. Fig. 31).

6.7.2 Using the chainsaw with one hand

Do not work with one hand if you are in an unstable working position or when using a chainsaw instead of a handsaw to cut small sized branches.

The chainsaw must be used with one hand only when:

• the operator is not able to reach a working position that allows him to use both hands,
• the operator needs to use one hand to support himself in the working position,
• the cutting involves extension of the operator's upper limb beyond his own body line (Fig. 32).

The operator must never:

• perform cutting operations with the kickback area corresponding with the point of the chainsaw bar;
- "hold and cut" sections;
- attempt to catch falling sections.

6.9) when moving between work areas.

⚠️ Stop the machine immediately if the chain stops during sawing.

If the chainsaw should get stuck during pruning high up (using a rope and a belt harness), the operator must:

1. stop the machine immediately;
2. fasten it securely to the part of the branch between the trunk and the cut section or to a rope not attached to the tool;

3. pull the chainsaw out from the cut, lifting the branch where necessary;

4. if necessary, use a handsaw or second chainsaw to free the trapped chainsaw, cutting at a minimum distance of 30 cm from the trapped chainsaw. Cutting operations to free the chainsaw must always be performed towards the end of the branch, (i.e. between the trapped chainsaw and the end of the branch and not between the trunk and the trapped chainsaw). This will prevent the chainsaw from being dragged by the part of the branch that is cut away, which would complicate the situation even further.

6.9 STOP

To stop the machine:

1. Release the throttle trigger lever (Fig. 13.A).
2. Press the safety button and turn off the electrical circuit (light off) (Fig. 12.A).

After releasing the throttle control it takes a few seconds for the toothed chain to stop.

Always stop the machine:

– when moving between work areas.

Do not keep your finger on the safety button when moving the machine to avoid accidentally enabling the machine.

6.10 AFTER USE

1. Remove the battery from its housing and recharge it (par. 7.2.2).
2. Mount the bar cover.
3. Allow the motor to cool before storing in an enclosed space.
4. Loosen the bar fastening nut to reduce chain tension.
5. Carefully remove any dust and debris and remove all traces of sawdust or oil deposits from the chain (par. 7.4).
6. Check there are no loose or damaged components. If necessary, replace the damaged components and tighten any screws and loose bolts.

IMPORTANT Always remove the battery (par. 7.2.2) and fit the blade guard whenever the machine is unused or left unattended.

7. ROUTINE MAINTENANCE

7.2 BATTERY

7.2.1 Battery power reserve

Battery autonomy is mainly influenced by:

a. environmental factors, that cause higher energy requirements:
– cutting trees and branches that are too thick;
b. operator behaviour that should be avoided:
– switching the machine on and off frequently whilst working;
- adopting a cutting technique that is unsuitable for the work to be performed (par. 6.6, par. 6.7);

To optimise battery power reserve it is always recommended to:

• cut wood when dry;
• use the most appropriate technique for the work to be performed

If the need arises to use the machine for sessions which exceed the capability of a standard battery, it is possible to:

• purchase a second standard battery to immediately replace the discharged battery, without compromising the continuity of operations;

7.2.2 Battery removal and recharging

1. Press the button placed on the battery 14.A) and remove it (Fig. 14.B);

7.2.3 Refitting the battery on the machine

When recharging is completed:

1. Remove the battery (Fig. 34.A) from the housing in the battery charger (do not keep charging when recharging is completed);
2. Disconnect the battery charger from the electrical outlet (Fig. 34.B);
3. Fit the battery (Fig. 14.B) in its housing pressing down until you hear it click firmly into position which ensures the electrical contact;

7.3 TOPPING UP THE CHAIN OIL TANK

NOTE The following symbol is found near the chain oil tank cap (fig. 35.A):

Chain oil tank

IMPORTANT Only use chainsaw oil or adhesive oil for chainsaws. Do not use oil containing impurities so as not to block the oil filter and to prevent irreparable damage to the oil pump.

It is essential that you use good quality oil to lubricate the cutting parts effectively. Used or poor quality oil does not

guarantee good lubrication and reduces the working life of the chain and bar.

IMPORTANT Never run the chain without sufficient oil, this could damage the saw and compromise safety.

Check the amount of oil in the chainsaw by checking the oil level indicator (Fig. 35.B).

If the oil level is low, top up as follows:

1. Unscrew and remove the cap (Fig. 35.A) from the oil tank.
2. Pour oil in the tank and monitor the level on the indicator (Fig. 35.B).
3. Make sure no impurities penetrate the oil tank when filling.
4. Screw on the oil cap and tighten it.

7.4 CLEANING

7.4.1 Cleaning the machine and the motor

After every work session, clean the machine thoroughly to remove all dust and debris.

• To reduce fire hazards, keep the machine and, in particular, the motor free of leaves, branches or excessive grease.
• Always clean the machine after use with a damp cloth dipped in neutral detergent.
• Remove all traces of humidity using a soft damp cloth. Humidity can generate risks of electric shocks.
• Do not use aggressive detergents or solvents to clean the plastic parts or hand grips.
• Do not spray water onto the motor and electrical components and prevent them from getting wet.
• To avoid overheating and damage to the motor or the battery, always keep the cooling air vents clean and free of debris.

7.4.2 Cleaning the chain

Remove any traces of sawdust or oil deposits from the chain every time it is used.

If there is excessive dirt or resin build-up, disassemble the chain and place it in a container with a specific cleanser for a few hours. Then rinse it with clean water and treat it with a suitable anticorrosive spray, before reassembling on the machine.

7.5 CHAIN CATCHER

Check the chain stop pin conditions before each use (Fig. 1.H) and repair in the event of damages.

7.6 MACHINE AND BAR LUBRICATION HOLES

Before daily use, remove the guard (par. 4.2), disassemble the bar and check that machine lubrication holes (Fig. 36.A) and guide bar (Fig. 36.B) are not clogged.

7.7 NUTS AND BOLTS

• Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition.
• Check regularly that the handles are fixed firmly.

8. OCCASIONAL MAINTENANCE

Have your dealer check the condition of the metal band around the clutch housing once a month. The band must be replaced if deteriorated or deformed.

8.2 CHAIN DRIVE SPROCKET

Regularly check the condition of the sprocket with your local dealer and replace it when wear exceeds the accepted limits.

Do not mount a new chain with a worn sprocket or vice-versa.

8.3 MAINTENANCE OF THE TOOTHED CHAIN

To ensure that the chainsaw works safely and efficiently, it is essential that the cutting means are well-sharpened.

⚠️ Always wear heavy duty gloves when handling the bar and chain.

Chain sharpening is necessary when:

– The sawdust looks like dust.
– Cutting becomes more difficult.
- The cut is not straight.
– Vibrations increase.

⚠️ Kickback may occur if the chain is not sufficiently sharpened

IMPORTANT It is recommended to have an Authorised centre sharpen the chain using the right tools to ensure minimum removal of material and even sharpness on all the cutting edges.

8.3.1 Replacing the toothed chain

Replace the chain whenever:

– the length of the cutting edges reduces to 5 mm or less;
– there is too much play between the links and the rivets.
– the cutting speed is too slow and the repeated sharpening does not improve the cutting speed. The chain is worn.

IMPORTANT After replacing the chain, its tension level must be checked more frequently due to settling of the chain.

8.4 GUIDE BAR MAINTENANCE

NOTE Any work on the guide bar requires specific experience and special tools in order to achieve top workmanship standards; for safety purposes, we recommend you contact your dealer to ensure work is done correctly.

To avoid asymmetrical wear on the bar, make sure it is turned over periodically.

To keep the bar in perfect working order, proceed as follows:

1. grease the bearings on the nose sprocket (if present) with the syringe (not included).
2. clean the bar groove with the scraper (not included) (Fig. 37.A);
3. clean the lubrication holes (Fig. 37.B);
4. with a flat file, remove burr from the edges and level off the guides.

8.4.1 Replacing the bar

Replace the bar whenever:

– the groove is not as deep as the height of the drive links (which must never touch the bottom);
– the inside of the guide is worn enough to make the chain lean to one side.
