General Safety

WARNING! When using cordless yard tools, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury, including the following:

Work Area Safety

1. Keep work area clean and well lit - Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while operating a power tool - Distractions can cause you to lose control.

Electric Safety

1. Power tool plugs must match the outlet. Never modify the plug in any way – Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfaces

Personal Safety

1. 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 inattention while operating power tools may result in serious personal injury.
2. 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.
3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting battery pack, picking up or carrying the tool – Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
4. 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.
5. Do not overreach. Keep proper footing and balance at all times – This enables better control of the power tool in unexpected situations.
6. 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.
7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used – Use of dust collection can reduce dust-related hazards.

Power Tool Use and Care

1. Do not force the power tool. Use the correct power

2. Keep cutting tools sharp and clean - Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

3. Use the power tool, accessories etc. in accordance with these instructions, taking into account the working conditions and the work to be performed - Use of the power tool for operations different from those intended could result in a hazardous situation.

Battery Tool Use and Care

WARNING! Read all safety warnings and instructions.

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

1. 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 battery pack.
2. Use appliances only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
3. When the 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.
4. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
5. Do not use a battery pack or appliance that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.

Chain Saw Safety Warnings

• Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating the chain saw may cause entanglement of your clothing or body with the saw chain.
• Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.
• Hold the power tool by insulated gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a 'live' wire may make exposed metal part of the power tool 'live' and give the operator a electric shock.
• Wear safety glasses and hearing protection. Further protective equipment for head, hands, legs and feet is recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.
• Do not operate the chain saw in a tree. Operation of a chain saw while up in a tree may result in personal injury.
  • Always keep proper footing and operate the chain saw only when standing on a fixed, secured and level surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chain saw.
• When cutting a limb that is under tension, be cautious of spring back. When the tension in the wood fibers is released, the spring-loaded limb may strike the operator and/or throw the chain saw out of control.
• Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.

- Do not grasp the exposed cutting blade or cutting edges when picking up or holding the saw. Be sure to encase the cutting bar in its protective sheath when not in use.

Causes and operator prevention of kickback

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

Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator.

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

Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.

Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

• Maintain a firm grip (right hand on the rear handle and left hand on the front handle with thumbs and fingers encircling the respective handles) and position your body and arms to allow you to resist kickback forces. Kickback forces can be controlled by the operator if proper precautions are taken. Do not let go of the chain saw.
• Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the unit in unexpected situations.
• Only use replacement bars and chains specified by the manufacturer. Incorrect replacement of bars and chains

  • To avoid the risk of fire, do not leave the machine with the motor hot on leaves or dry grass.

⚠ WARNING! It takes specific training to use the machine for felling and delimbing.

Checks During Work

- Checking the chain tension

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

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

⚠ WARNING! Never work with the chain loose, as it can be hazardous if the chain slips out of its guide.

To adjust the chain tension, follow the instructions in "Adjust Chain Tension" on pages 12.

Checking the oil delivery

IMPORTANT! Never use the machine without lubrication! You can check the oil level in the tank through the transparent gauge. Make sure you fill up the oil tank every time you use the machine. For best results, use only a good quality bar and chain oil designed specifically for use with chain saws.

⚠ WARNING! Make sure the bar and the chain are in place when you check the oil delivery.

Start the motor and check if the chain oil is delivered as shown below (Fig. 10).

Proper Cutting Stance

• Weight should be balanced with both feet on solid ground.
• Keep your left arm and elbow locked in a "straight arm" position to withstand any kickback force (Fig. 11).

Fig. 11

Chain line Straight arm

• Your body should always be to the left of the chain line.

Basic Cutting Procedures

WARNING! This unit is designed for trimming branches and limbs up to recommended 8.5 in. (21.6 cm), not to exceed a max. cut of 9.5 in. (24.1 cm) in diameter depending on type of wood. Practice cutting a few small limbs using the following technique to get the "feel" of using the saw before you begin a motor emitting aperture.

Cutting Techniques

Before felling or delimbing for the first time, practice sawing logs on the ground or on trestles, so that you can get familiar with the machine and the most suitable sawing techniques.

WARNING! Always hold the machine with both hands when sawing.

WARNING! Stop the motor immediately if the chain stops during sawing. Beware of kickback, which can occur if the bar contacts an obstacle.

- Felling a tree

i) When bucking and felling are performed by two or more people at the same time, the felling operation should be separated from the bucking operation by a distance of at least twice the height of the tree being felled. Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage. If the tree does make contact with any utility line, the company should be notified immediately.
ii) The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled.
iii) An escape path should be planned and cleared as necessary before cuts are started. The escape path should extend back and diagonally to the rear of the expected line of fall as illustrated (Fig. 12).

Fig. 12

Fig. 13

2 inch (50 mm) 2 inch (50 mm)

Make the lower horizontal notching cut first. This will help to avoid pinching either the saw chain or the guide bar when the second notch is made.

- Felling back cut

i) Make the felling back cut at least 2 in. (50 mm) higher than the horizontal notching cut as illustrated (Fig. 12). Keep the felling back cut parallel to the horizontal notching cut. Strategically position the felling back cut so that enough wood is left to act as a hinge. The hinge wood keeps the tree from twisting and falling in the wrong direction. Do not cut through the hinge.
ii) As the felling gets close to the hinge, the tree should begin to fall. If there is any chance that the tree may not fall in the desired direction or it may rock back and bind the saw chain, stop cutting before the felling back cut is complete and use wedges of wood, plastic or aluminium to open the cut and drop the tree along the desired line of fall.
iii) When the tree begins to fall, remove the chain saw from the cut, stop the motor, put the chain saw down, then use the retreat path planned. Be alert for overhead limbs falling

⚠ WARNING! Pay special attention to where the branches are lying on the ground and recognize the following risks: 1). the branches may be under tension; 2). the direction in which the branch will fall may differ from that anticipated; 3). the tree may be unstable after the branch has been cut.

- Bucking a log

WARNING! Do not buck logs that are larger than the maximum cutting thickness.

Bucking is the process in which a log is cut into lengths. It is important to make sure your footing is firm and your weight is evenly distributed on both feet. When possible, the log should be raised and supported by the use of limbs, logs, or chocks. Follow these simple directions for easy cutting;

- When the log is supported along its entire length as illustrated (Fig. 15A), cut from the top (overbuck).

Fig. 15A

- When the log is supported on one end (Fig. 15B), cut 1/3 the diameter from the underside (underbuck). Then make the finishing cut by overbucking to meet the first cut.

Fig. 15B

Fig. 15C ① ②

- It is easier to saw a log using the spiked bumper (Fig. 15D).

- Dig the spiked bumper into the log and use it as a pivot. Cut with an arched motion to make the bar penetrate the wood.

- Repeat several times if necessary, changing the point where you plant the spiked bumper.

Replacing the Guide Bar and Chain

NOTE: When replacing the guide bar and chain, use only identical replacement parts. Make sure the battery is not inserted in the compartment before proceeding with operation.

WARNING! Always wear heavy-duty gloves when handling the bar and chain. Mount the bar and chain very carefully so as not to impair the safety and efficiency of the

2. Lay out the new saw chain in a loop and straighten any kinks. THE SHARP SIDE OF THE TEETH MUST FACE AWAY FROM YOU IN THE DIRECTION OF THE CHAIN ROTATION INDICATED ON THE GUIDE BAR → If the teeth face backwards, turn the loop over (Fig. 18).
   

NOTE: A new chain tends to stretch; check the chain tension frequently, and adjust tension as required.

Chain Tension

Check the chain tension before using the saw when the chain is cold. The correct tension of a cold chain is when there is no slack on the underside of the guide bar; the chain is snug, but you can rotate it by hand without binding.

During normal saw operation, the temperature of the chain will increase. The drive links of a correctly tensioned warm chain will hang approximately 0.050 in. (1.25 mm) out of the bar groove (Fig. 22). Be aware that a chain tensioned while warm, may be too tight upon cooling. Check the "cold tension" before next use. The chain must be re-tensioned whenever the flats on the drive links hang out of the bar groove (Fig. 22).

Chain Sharpening

⚠ WARNING! To ensure that the saw works safely and efficiently, it is essential that the cutting components are well charged. It is highly recommended to replace the

If you sharpen the chain by yourself, it's recommended to purchase Sun Joe ^b 24V-CSSHFRP-LTE chain saw sharpener, which can be powered by the same 24V iON+ battery with this cordless chain saw. Visit sunjoe.com or call the Snow Joe ^b + Sun Joe ^e customer service center at 1-866-SNOWJOE (1-866-766-9563) to order.

Otherwise, use special round-section files with the right diameter depending on the type of chain (see "Chain Maintenance Table" pg. 23). You need a certain amount of skill and experience to avoid damaging the cutting edges.

Sharpen the chain as follows (Fig. 23):

• Secure the bar firmly, with the chain mounted, in a suitable vise.
• Tighten the chain if it is loose.
• Mount the file in the guide and then insert it in the tooth at a constant angle from the cutting edge.
• Sharpen in a forward motion a few times and repeat this on all the cutting edges facing the same way (right or left).
  • To move the chain forward, use a screwdriver.
• Turn the bar over in the vise and repeat on all the other cutting edges.
• Check that the depth limiter tooth does not stick out farther than the inspection tool and file any projecting parts with a flat file, rounding off the edges (Fig. 23).
• After sharpening, remove all traces of filing and dust and lubricate the chain in an oil bath. Replace the chain whenever:
• The length of the cutting edges decreases to 5 mm or less;
• There is too much play between the links and the rivets.

Guide Bar Maintenance

When the guide bar shows signs of wear, turn it over on the saw to distribute the wear for maximum bar life. Feathering or burring of the bar rails is a normal process of bar wear. You should smooth such faults with a file as soon as they occur. Replace a bar with any of the following faults:

• wear inside the bar rails permitting the chain to lay over sideways
• bent guide bar
• cracked or broken rails
• spread rails

Turn the saw over, check the underside of the guide bar, and make sure that the lubrication holes and chain groove are free from impurities.

Chain Sprocket

Regularly check the condition of the sprocket and replace it when wear exceeds 0.5 mm (Fig. 24).

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

CAUTION!

• Remove the battery and wait at least five minutes for the saw to cool before servicing or storing your unit.
• If you drop the saw, carefully inspect it for damage. If the guide bar is bent, the housing is cracked, the handle is broken, or if you see any other condition that may affect the saw's operation, DO NOT USE the tool. Instead, have it serviced at an authorized Snow Joe ^b + Sun Joe ^b dealer or call the Snow Joe ^b + Sun Joe ^b customer service center at 1-866-SNOWJOE (1-866-766-9563).
