WICHTIGE INFORMATION

1 All operators should read this manual carefully before using this chainsaw.

Wear suitable clothing. This should include snugly-fitting (safety) clothing, sturdy boots, heavy duty gloves, goggles or a face screen and ear plugs or ear mufflers. Wear a helmet if there is risk of falling objects or projections from trees.

2 Always hold the chainsaw firmly with both hands when the engine is running. Always maintain a firm foothold. Ensure you are able to stop the engine quickly if necessary. Do not work up a tree unless you have received suitable training and have the appropriate equipment (belts, ropes, safety hooks etc) for this type of work. We strongly recommend that all first-time chainsaw users obtain practical instruction on safe chainsaw usage before operating the chainsaw. Do not operate this machine when tired or under the influence of any substances, drugs or alcohol which can impair vision, dexterity or judgement. Prolonged use of chainsaws or other machines exposing the operator to vibration may produce Whitefinger's Disease (Raynaud's Phenomenon). This may reduce the hands' ability to feel and regulate temperature and may produce general numbness. Continual or regular users should therefore monitor closely the condition of their hands or fingers. If any of the symptoms appear, seek immediate medical advice.

3 Never carry the chainsaw with the engine running. Whenever carrying a chainsaw, even for short distances, the chain should be covered by the chain guard (scabbard) and the bar should point backwards. When transporting the chainsaw in a vehicle, secure the saw to prevent fuel spillage.
4 To avoid kick-back, do not attempt to cut with the nose of the bar. Ensure the engine is running at full throttle before commencing to cut. To avoid kick-back, do not let the nose of the bar come into contact with logs, branches, the ground or any other obstruction. Do not allow any part of the chain to come into contact with rock, nails or wire fence. Ensure the chain is kept sharp and correctly

tensioned. Keep the spike or the saw body against the wood when cutting. Use only genuine accessories and spare parts. We recommend you have your unit periodically checked and serviced by an authorised dealer. Do not use chainsaw above shoulder height.

5 Do not operate the chainsaw near a naked flame or spilled fuel. Only operate the chainsaw outside and in well ventilated areas. After re-fueling, always wipe off any spilled fuel. Move the chainsaw away from the fueling point before starting the engine.

6 Keep by-standers and animals out of the work area; at a minimum distance of 10m or twice the timber length necessary, use warning signs to keep on-lookers at a distance.

Carefully survey the working site to note any hazards, eg. roads, paths, electricity cables, dangerous trees etc. Do not use the chainsaw if the device stopping the chain (safety chainbrake) does not work correctly.

Never place hands on the chain whilst the engine is running.

Ensure someone is within hearing distance in case of an accident. If this is not possible, it is recommended that users operating chainsaws in remote areas carry an adequate first-aid kit with them and ensure someone knows their location.

Never leave the engine running whilst the tool is unattended.

ONLY USE ORIGINAL SPARE PARTS AND ACCESSORIES.

BAR AND CHAIN INSTALLATION

Ensure engine is always switched off before fitting or adjusting chain. Wear a pair of protective gloves when fitting or adjusting chain.

A. Clutch guard
B. Inner bar plate
C. Bar mounting bolts
D. Chain tensioning screw
E. Oil hole
F. Outer bar plate
G. Bar retention nuts
H. Sprocket
I. Adjusting screw

Remove the clutch guard (A) and the outer bar plate (F). Check that the oil hole (E) is free from impurities. Fit the chain over the sprocket (H). Ensure correct direction of cutter tooth. Put the bar in position over studs (C) slide it towards the sprocket. Fit the chain into the bar groove and slide the bar forwards.

Make sure that the tang chain tensioning screw (D) fits into the hole in the bar (E). Replace the outer bar plate and the clutch guard. Screw the two bar retention nuts finger tight (G). Tension the chain by turning the adjusting screw (I) clockwise while raising the tip of the bar. The tension is sufficient if the chain is snug on the bar but still moves freely around the bar when pulled by hand. Tighten the two bar retention nuts securely.

Always use the combination tool to install and tension the chain.

WARNING

Mount the bumber spike as shown in illustration.

RUNNING IN A NEW CHAIN

The chain must always be cold when carrying out adjustment.

1 Let the chain run slowly for a few minutes. Check that the oil pump is delivering oil onto the chain.
2 Stop the engine and adjust the chain tension.
3 Check the tension of a new chain more frequently during initial usage and adjust as necessary.
4 Repeat adjusting until the chain does not stretch any more.

Never touch the chain while the engine is running.

FUEL MIX

Use only fuel recommended by this manual. This product is fitted with a 2-stroke engine and therefore requires a 2-stroke petrol and oil mix. Use leaded or unleaded petrol with a minimum octane rating of 90. When using leaded petrol, use 2.5% (40:1) of McCulloch oil, otherwise use 5% (20:1) of a high quality 2-stroke engine oil (from a recognised brand). When using unleaded petrol, use 2.5% (40:1) of McCulloch oil or use 2.5% (40:1) of a high quality synthetic 2-stroke engine oil..

Only use oil from sealed containers. In order to obtain a good fuel mix, put the oil into the container before the petrol.

IMPORTANT

Always shake this fuel mix vigorously each time you use it. Fuel mix properties deteriorate with time, we therefore recommend that you only make the quantity of fuel mix you will need for each usage. Do not use fuel mix more than a week old as this could damage the engine.

WARNING

Do not smoke when re-fuelling. Always open the fuel cap slowly. Re-fuel in open spaces only, keeping away from naked flames or sparks.

Always store fuel in an approved container.

SAFE STORAGE OF FUEL

Petrol is highly inflammable. Put out all cigarettes, pipes and cigars before working with petrol. Avoid spilling petrol. Store fuel in a cool, well ventilated place, in an approved container specifically designed for the purpose. Never store engine with fuel in the tank in enclosed, poorly ventilated areas, where fuel fumes may reach an open flame, spark or pilot light such as in a furnace, water heater, clothes dryer etc. Petrol fumes can cause an explosion or a fire. Do not store large amounts of fuel. To prevent possible restarting problems avoid running the fuel tank dry. This also helps to extend engine life.

CHAIN LUBRICATION

IMPORTANT The service life of the bar and chain depends on good lubrication.

Always use chain lubricating oil of medium viscosity. We recommend special McCulloch chain lubricating oil. Never use waste oil for this purpose. This results in damage to the bar, the chain and the oil pump. Refill the chain oil tank each time the saw is refuelled.

NOTE: Saw chain stretches during use, particularly when it is new, and it will occasionally be necessary to adjust and tighten it. A new chain will require adjustment after about 5 minutes of operation.

• The mechanical oil pump for chain lubrication can be adjusted.

The feed rate of the chain oil pump can be adjusted by means of the regulating screw (A) (see details in the illustration). The oil feed rate is increased by turning the regulating bolt counterclockwise.

IMPORTANT - The chain oil feed is reduced to a minimum when the regulating bolt is completely closed (turning clockwise).

E STARTING AND STOPPING

IMPORTANT - Never start or operate the saw unless bar and chain are properly installed. Before starting always move the saw away from the fuelling area and place it on firm, flat surface, the guide bar to the front.

STARTING A COLD ENGINE

Check that the chain brake is in the disengaged position moving the lever (L) backwards (towards the front handle). Check that the ignition switch is not in the "STOP" position.

Depress throttle trigger lockout (A).Depress throttle trigger (B) and then pull up the throttle lock (C).

Release first the throttle trigger (B) and then the throttle lock (C).

In this way the throttle lock engages and your left hand is free to grip the saw firmly.

Pull out the choke control (E). Activate the decompression pressing the valve (D). Hold the saw firmly as shown in illustration and pull the starter rope until the engine fires once.

Push in the choke control (E). Re-activate the decompression system by depressing valve (D). Pull the starter rope until the engine starts.

Allow engine to warm up for a few seconds, holding the saw firmly.

Beware of moving chain.

Release the safety lock by pressing the throttle trigger (B).

STOP. The engine is stopped by moving the ignition switch to STOP position.

IMPORTANT. After lengthy use of the chain saw at full speed, we recommend to run the engine for a few seconds at idle speed before stopping it.

STARTING A WARM ENGINE

Check that the ignition switch is not in the "stop" position and do not use the throttle lock.

Hold the saw firmly, press valve (D) for decompression and pull the starter rope.

STARTING A WARM ENGINE AFTER FUELLING

In the fuel tank as run completely dry, proceed to start as with a cold engine.

F USAGE

IMPORTANT. Before using a chain saw read carefully the Operator's Manual and all safety precautions carefully.

FELLING TREES.

• Make sure that there are no bystanders or animals in the work area.

• Study the direction of the fall of the tree and then plan your exit path away from the planned direction of fall.

• Don't fell trees when there is a strong wind.

1 Clear the tree base of interfering limbs and brush. Clean the work area from stones or other objects which could damage the chain. If the tree has large protruding roots, remove them before felling (see illustrations).

2 A) Cut a felling notch (A) of 45^ on the side you want the tree to fall to a depth of about one third of the trunk diameter (d).

Then make a felling cut (B) about 5 cm higher than the felling notch on the opposite side of the tree. Make sure that the felling cut does not go right through the trunk. A hinge (C) must always be left to provide control over the direction of the fall.

B) Use wedges to control the moment and direction of the fall.

3 When the tree starts to fall, walk away along your preplanned escape path.

4 A) Limbing thick branches. For limbing and bucking leave the lower limbs to support the log off the ground.

B) Supported at one end only. Begin with a bottom cut made by the upper side of the bar (A); the depth of the cut should be about one third of the log diameter (A). Finish with a top cut (B) meeting the first one. With this technique splitting, cracking can be avoided.

C) Supported at both ends. Begin with a top cut about one third of the log diameter. Then finish with a bottom cut (B) meeting the first one. This technique avoids the risk of pinching the bar in the log.

D) If the log is supported along its whole length it may be cut normally from above. Take care not to touch the ground with the chain.

• When working on a slope always stand on the uphill.

• When cutting prepared timber, use clamps or chocks to secure work.

• Use extreme caution when cutting small size brush and saplings which may catch the chain and pull you off balance.

CARBURETTOR ADJUSTMENT

N.B. We suggest carburetor adjustments are made by an authorized service dealer.

The carburetor has three adjustment possibilities:

• L: The needle screw (L) governs the fuel flow at low speed and also the acceleration from low to full speed.

To set screw (L): close screw (L) turning it clockwise without forcing . Then open screw 1 full turn (counterclockwise).

If acceleration is not smooth, open another 1/8 turn to increase fuel flow.

• H: The needle screw (H) governs fuel flow at high speed (throttle valve fully open).

To set hi speed screw (H): close screw (H) turning it clockwise without forcing.

Then open screw 1-1/2 full turn (counterclockwise).

If the engine speed is too high (the maximum speed with bar and chain on should not exceed 11.500min^-1 ), open the screw about 1/8 turn (counterclockwise).

• I: The (I IDLE) screw controls the throttle opening to govern idle speed (2.500min^-1)

CAUTION: increased idle speed may cause chain movement. The carburator is adjusted for normal operation during production. Wen considerable changes of altitude require a supplementary adjustment, contact an authorised service station which offers the latest in tools, parts and technical assistance.

ROUTINE MAINTENANCE

Ensure engine is always switched off before any kind of maintenance operation.

CHAIN: Check tension regularly. A new chain will require more frequent adjustment. Loosen retention nuts. adjust chain (see assembly instructions). Tighten retention nuts.

1 BAR

• Clean the bar groove (K) and check the lubrication holes (L) in the bar to ensure that they are not clogged.
  Grease sprocket periodically. Rotate sprocket and repeat.
• Rotate bar periodically to maximise bar life.

2 AIR FILTER

• A dust clogged air filter may cause carburetor problems. This may prevent the engine from reaching its maximum r.p.m. and cause high fuel consumption.
• Remove cover.
• Wash filter in petrol (do not use fuel which is mixed with oil).
• The filter can also be cleaned with compressed air.
• Replace filter if damaged or if it does not seal tightly in the air box.

3 SPARK PLUG

Remove and clean the spark plug every 30 hours. Check the electrode gap (0,5 / 0,6mm)

• Replace spark plug about every 100 working hours or whenever it is extremely encrusted.
  Heavily encrusted electrodes can result from an incorrect carburetor setting or from wrong fuel mixture (too much oil in the fuel mix) or a poor quality of oil in the fuel mix. Check and correct.

4 OIL FILTER

The oil filter is end of the oil suction hose inside the oil tank. To clean and replace the filter pull it out through the oil tank filter opening. Use a piece of bent wire or long forceps. To remove deposits from the oil tank half fill it with kerosene or petrol and shake thoroughly. Drain off and fill the tank with fresh saw chain oil. Never use waste oil.

5 FUEL FILTER

To change fuel filter remove the tank cap and pull out the filter with a piece of bent wire or long forceps. Replace the filter as shown in the illustration and reposition it.

It is recommended to replace the fuel filter at least once a year.

CHAIN BRAKE

WARNING: Contact your service dealer if anything appears wrong with your chain brake.

Do not disassemble or manipulate the mechanism of the chain brake.

• Clean the brake mechanism periodically (without disassembling it) and control the wear of the band visually.
  PERIODICALLY: It is important to clean the saw thoroughly particularly around cylinder fins to avoid overheating of the engine.
• LONG STORAGE: Empty fuel and run engine until dry.

CHAIN BRAKE

TESTING

Your chainsaw is fitted with an automatic safety chainbrake designed to stop the chain in milliseconds in case of kickback. Always hold the saw firmly in both hands.

The chain brake does not provide total protection if the machine is used without taking the necessary precautions or carrying out proper maintenance.

The chain brake can also be engaged manually by pushing the chain brake lever forwards. The manual use of the chain brake is recommended only at idle.

Always test the chain brake before using your saw. Do this at idle by engaging the brake (see below).

Always release the brake before starting.

Kickback may occur if the end of the bar (see illustrated angle) touches any solid object or if the top of the bar becomes pinched in the wood.

Never attempt to start a cut with the end of the bar.

Kickback is a violent upward or rearward movement of the bar and may cause you to lose control of the machine.

Always keep a firm grip on the saw with both hands because, in case of kickback, it is the contact of the left hand with the brake lever which will help to engage the brake.

CAUTION: Initial contact with the wood may occasionally cause the chain to buck, and if the chain teeth are not correctly sharpened, the chain may skate on the wood.

1 The chain brake is disengaged when brake lever is pulled back and locked (chain can move).
2 The chain brake is engaged when brake lever is in forward position (chain is stopped).

The chain brake should snap into both positions.If strong resistance is felt or lever does not move into either position, DO NOT USE YOUR SAW.

Take it immediately to an authorized servicing dealer.

3 CHAIN CATCHER

This unit is fitted with a chain catcher below the drive spocket. This is intended to stop the rearward movement of th chain in case of breakage or if it should come out of the bar, It should never be removed.

CHAIN SHARPENING

1 The cutter teeth should be sharpened with a round 7/32" file.

The job can be made easier by also using a file holder.

The chain can remain fitted on the bar during sharpening.

Before commencing, the chain should be tensioned correctly and the chain brake should be activated to prevent the chain from moving.

2 To obtain a correct sharpening the file must be carefully held to maintain 3 basic angles:

• A Top angle 30^ - 35^
• B External,side angle 85^ - 90^
• C Internal, side angle 60°.

File in one direction only, from the "inside" of the cutter tooth towards the "outside".

Do not allow the file to touch the chain as you bring it back to re-position it. Each cutter tooth should be filed with the same number of strokes.

3 The file should be held horizontally to the cutter tooth being sharpened.
4 Best results to obtain a precise sideways angle can be obtained by holding the file so that it rises 0,5 mm above the top face of the cutter tooth.

5 DEPTH GAUGE

Correct depth gauge height is vital to ensure maximum chain life and cutting efficiency.

The height of the depth gauge should be lowered as the cutter tooth is filed back; this height should be checked every 4 or 5 sharpenings.

The best way to do this is to use a flat file and a depth gauge tool.

The correct setting is 0.65mm below the top edge of the cutter tooth.

The cutter tooth depth gauge should then be rounded (D).
