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.
· Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw, always fit the cutting chain sheath. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
· Follow instructions for lubricating, chain tensioning and changing accessories. An improperly tensioned or poorly lubricated chain may either break or increase the chance for kickback.
· Keep handles dry, clean and free from oil and grease. Greasy, oily handles are slippery and can cause loss of control.
· Cut wood only. Do not use the chain saw for any other purpose. For example, do not use the chain saw to cut plastic, masonry or non-wood building materials. Using the chain saw in these incorrect ways could result in serious damage to you and your tool.

· Keep guards in place. Protective guards should be checked periodically to ensure they are properly fitted and in correct working order.
· 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 may cause chain breakage and/or kickback.
· Never use a dull or loose chain. Keep the chain sharp and properly tensioned.
· Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

A short-circuited battery pack poses a risk of fire and severe personal injury.
· Store your battery pack and charger in a cool, dry place Do not store the battery pack or charger where temperatures may exceed 105ºF (40.5ºC), such as in direct sunlight or inside a vehicle or metal building during the summer.
Information about the battery
1. The battery pack supplied with your cordless chain saw is only partially charged. The battery pack has to be charged completely before you use the tool for the first time.
2. For optimum battery performance, avoid low discharge cycles by charging the battery pack frequently.
3. Store the battery pack in a cool place, ideally at 77°F (25°C) and charged to at least 40%.
4. Lithium-ion batteries are subject to a natural aging process. The battery pack must be replaced at the latest when its capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery pack are no longer capable of meeting the high power requirements needed for the proper operation of your chain saw, and therefore pose a safety risk.
5. Do not throw battery pack into an open fire as this poses a risk of explosion.
6. Do not ignite the battery pack or expose it to fire.
7. Do not exhaustively discharge the battery. Exhaustive discharge will damage the battery cells. The most common cause of exhaustive discharge is lengthy storage or non-use of partially discharged batteries. Stop working as soon as the performance of the battery falls noticeably or the electronic protection system triggers. Place the battery pack in storage only after they have been fully charged.
8. Protect the battery and the tool from overloads. Overloads will quickly result in overheating and cell damage inside the battery housing even if this overheating is not apparent externally.
9. Avoid damage and shocks. Immediately replace batteries that have been dropped from a height of more than one meter or those that have been exposed to violent shocks, even if the housing of the battery pack appears to be undamaged. The battery cells inside the battery may have suffered serious damage. In such instances, please read the waste disposal information for proper battery disposal.
10. If the battery pack suffers overloading and overheating, the integrated protective cutoff will switch off the equipment for safety reasons.

IMPORTANT! Do not press the ON/OFF switch any more if the protective cut-off has been activated. This may damage to the battery packs.
11. Use only original battery packs. The use of other batteries poses a fire risk and may result in injuries or an explosion.
Information about the charger and the charging process
1. Please check the data marked on the rating plate of the battery charger. Be sure to connect the battery charger to a power supply with the voltage marked on the rating plate. Never connect it to a different mains voltage.
2. Protect the battery charger and its cord from damage. Keep the charger and its cord away from heat, oil and sharp edges. Have damaged cords repaired without delay by a qualified technician at an authorized Snow Joe® + Sun Joe® dealer or call the Snow Joe® + Sun Joe® customer service center at 1-866-SNOWJOE (1-866-766-9563).
3. Electrical plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with grounded appliances. Unmodified plugs and matching outlets will reduce the risk of electric shock.
4. Keep the battery charger, battery pack and the cordless tool out of the reach of children.
5. Do not use the supplied battery charger to charge other cordless tools.
6. During periods of heavy use, the battery pack will become warm. Allow the battery pack to cool to room temperature before connecting it to the charger to recharge.
7. Do not overcharge the battery. Do not exceed the maximum charging times. These charging times only apply to discharged battery. Frequent insertion of a charged or partially charged battery pack will result in overcharging and cell damage. Do not leave the battery in the charger for days on end.
8. Never use or charge the battery if you suspect that it has been more than 12 months since the last time it was charged. There is a high probability that the battery pack has already suffered dangerous damage (exhaustive discharge).
9. Charging the battery at a temperature below 41°F (5°C) will cause chemical damage to the cells and may cause a fire.
10. Do not use battery that have been exposed to heat during the charging process, as the battery cells may have suffered dangerous damage.
11. Do not use batteries that have suffered curvature or deformation during the charging process or those that exhibit other atypical symptoms (gassing, hissing, cracking, etc.).
12. Never fully discharge the battery pack (maximum recommended depth of discharge is 80%). A complete discharge of the battery pack will lead to premature aging of the battery cells.

Before starting work please: · Check that all the screws on the machine and the guide bar are tightly fastened; · Check that the chain is tensioned correctly, sharp and there are no signs of any damage; · Check that hand grips and protection devices are clean and dry, correctly mounted and securely fastened to the machine; · Check that the chain brake is working efficiently; · Check that the trigger switch and the safety lock switch move freely without forcing and return automatically and rapidly back to their neutral positions; · Check that the trigger switch remains locked until the safety lock switch is slided back; · Make sure the cooling air vents are not clogged with sawdust or debris; · Check that the chain’s oil level is not below the bottom level mark; if necessary, top up the oil to 1 cm from the rim of the filler. NOTE: You must fill the chain oil tank with bar and chain oil before using your chain saw.
Adjusting the Chain Tension
mWARNING! Use protective gloves when handling the
bar and chain.
1. Make sure the front hand brake is not engaged. Loosen the sprocket/chain end cover a little by turning the end cover nuts counterclockwise with the included hex key wrench/blade screwdriver (Fig. 5).
Fig. 5
Sprocket/chain end cover
End cover nuts

2. Lift up the guide bar tip slightly. Use the other end of the hex key wrench/blade screwdriver to turn the chain adjusting screw clockwise to tighten, turn it counterclockwise to loosen. A cold chain will be correctly tensioned when there is no slack on the underside of the guide bar; the chain is snug, but it can be turned by hand without binding (Fig. 6).
Fig.6

Chain adjusting screw
3. Retighten the end cover nuts. Using a screwdriver, run the chain along the guide to check that it moves smoothly.
Chain Lubricant
IMPORTANT! Only use a good quality bar and chain oil designed specifically for use with chain saws to ensure optimal lubrication of the cutting parts. Do not use oil containing impurities to avoid clogging the tank filter and permanently damaging the oiler.
IMPORTANT! The chain lubricating oil is bio-degradable. The use of mineral oil or engine oil can have a serious impact on the environment. 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 lifespan of the chain and bar.
IMPORTANT! Before each use, the oil level should be checked and topped up to 1 cm from the rim of the filler. To fill the oil tank, remove the oil tank cap and add the recommended bar and chain oil. The oil level must not drop below the bottom level mark, as indicated beside the oil tank (Fig. 7).

Operation
Starting and Stopping
mCAUTION! Starting, stopping, and restarting an electric
motor repeatedly within a few seconds can generate a great deal of heat and damage the motor. To protect the life of your cordless chain saw, always wait at least five seconds after stopping before restarting the saw.
mWARNING! Be sure that the chain is not in contact with
any object when you start the motor.
mWARNING! Keep hands away from chain. Keep hands
on handles. Do not overreach.
A good, firm grip on the tool using both hands will help you maintain control. Maintain a firm grip by place your right hand on the rear handle and left hand on the front handle with thumbs and fingers encircling the respective handles. A firm grip combined with proper positioning of the handle against your body will help you maintain control of the saw. Do not let go of the saw while it is in operation.
mWARNING! Do not operate the cordless chain saw in
a tree, on a ladder, or on a scaffold. Using the tool under such circumstances is extremely dangerous.
mCAUTION! The chain will continue to run for several
seconds after turning off the tool.
Do not use the chain saw under wet conditions. Use extreme caution when cutting small brush, saplings, or limbs under tension because slender and tense material may catch the saw and be whipped toward you, pull you off balance, or spring back.
Do not use the chain saw to cut vines and/or small underbrush.
mWARNING! Do not let familiarity with this type of tool
prevent you from taking all necessary precautions. Remember that a careless fraction of a second is sufficient to inflict serious injury.
mWARNING! Do not cut trees near electrical wires. mWARNING! Failure to lubricate the chain will cause
damage to the bar and chain. Use only a good quality bar and chain oil designed specifically for use with chain saws.
NOTE: It is normal for oil to seep from the saw when not in use. To prevent seepage, empty the oil tank after each use. When storing the unit for a long period of time (3 months or longer), be sure the chain is lightly lubricated; this will prevent rust on the chain and bar sprocket.

1. Prior to each cutting session, run through the daily checklist (see pg. 20).
2. In the event of an accidental activation, the front hand brake will engage in the ON position to stop the machine. Reset the safety brake function by returning the front hand brake to the OFF position (Fig. 8).

Operating Tips mWARNING! For your safety and that of others:
1. Do not use the machine without reading the instructions carefully. Become acquainted with the controls and the proper use of the machine. Learn how to stop the machine quickly.
2. Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property.
3. Always wear suitable clothing when using the machine. Wear anti-vibration gloves and other personal protective equipment.
All the above-mentioned precautions do not, however, guarantee the prevention of certain risks i.e. Raynaud’s phenomenon or Carpal tunnel syndrome. For operators who use this machine for prolonged periods, it is therefore recommended to have periodic checkups on their hands and fingers. If any of the above mentioned symptoms should appear, please contact a physician immediately.
4. Work only in daylight or good artificial light. 5. Take utmost care when working near metal fences.
6. Take care not to hit the bar hard against foreign objects or flying debris caused by the movement of the chain.
7. Stop the motor and remove the battery from the compartment:
Whenever you leave the machine unattended
Before cleaning, checking or servicing the machine After striking a foreign object. Inspect the machine
for any damage and make repairs before restarting it again
If the machine begins to vibrate abnormally, immediately look for the cause of the vibrations and have the machine inspected at an authorized Snow Joe® + Sun Joe® dealer or call the Snow Joe® + Sun Joe® customer service center at 1-866-SNOWJOE (1-866-766-9563) for assistance
When the machine is not in use
IMPORTANT! Always remember that an incorrectly used chain saw may disturb others and have a serious impact on the environment.
To respect people and the environment:
· Avoid using the machine in environments or at times of the day when it may disturb others.
· Scrupulously comply with local regulations and provisions for the disposal of waste materials after sawing.
· Scrupulously comply with local regulations and provisions for the disposal of oils, damaged parts or any elements which have a strong impact on the environment.

· 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.
· To avoid the risk of fire, do not leave the machine with the motor hot on leaves or dry grass.
mWARNING! 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.
mWARNING! 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 page 11.
· 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.
mWARNING! 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. 11).
Fig. 11

13

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. 12).

Fig. 12 Chain line

Straight arm

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

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.
mWARNING! Always hold the machine with both hands
when sawing.
mWARNING! 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. 13).

Basic Cutting Procedures
mWARNING! 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 major sawing operation.
· Take the proper stance in front of the wood with the saw turned off (Fig. 12).
· Squeeze the trigger switch and let the chain accelerate to full speed before entering the cut.
· Hold the saw with both hands firmly. Always keep your left hand on the front handle and your right hand on the rear handle so that your body is to the left of the chain line.
· Keep the unit running the entire time you are cutting, maintaining a steady speed.
· Let the chain do the work; exert only light downward pressure. If you force the cut, damage to the bar, chain, or unit can result.
· Do not put the pressure on the saw at the end of the cut.
· Always cut with both feet on solid ground to prevent falling.
· Do not cut above chest height since it is difficult to control kickback forces with a saw held high.

Fig. 13
iv) Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind direction to help you judge which way the tree will fall.
v) Remove dirt, stones, loose bark, nails, staples and wire from the tree.
· Notching undercut Make the notch 1/3 the diameter of the tree, perpendicular to the direction of the fall as illustrated (Fig. 14).

14

2 inch (50 mm)

Fig. 14
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. 14). 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 and watch your footing. · Limbing Limbing is the process in which branches are removed from a fallen tree. When limbing, leave larger lower limbs to support the log off the ground. Remove the small limbs in one cut as illustrated (Fig. 15). Branches under tension should be cut from the bottom up to avoid binding the chain saw.

mWARNING! 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
mWARNING! 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. 16A), cut from the top (overbuck).
Fig. 16A
1

· When the log is supported on one end (Fig. 16B), cut 1/3 the diameter from the underside (underbuck). Then make
the finishing cut by overbucking to meet the first cut.

Fig. 16B

· When the log is supported on both ends (Fig. 16C), cut 1/3 the diameter from the top (overbuck). Then make the
finishing cut by underbucking the lower 2/3 to meet the first cut.

· It is easier to saw a log using the spiked bumper (Fig. 16D).
Fig. 16D Spiked bumper
Spiked bumper
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.
When bucking on a slope, always stand on the uphill side of the log. When cutting through the log, maintain control by releasing the cutting pressure near the end of the cut without relaxing your grip on the chain saw handles. Do not let the chain contact the ground.
After completing the cut, wait for the saw chain to stop before you move the chain saw. Always stop the motor before moving from tree to tree.

mDANGER! Never start the motor before installing the
guide bar, chain, and sprocket cover. Without all these parts in place, the clutch can fly off or explode, exposing the user to potentially serious injuries.
When you first purchase your chain saw, the chain and bar will come pre- assembled on the saw. Should you need to replace
the chain in the future, follow the steps below.
1. Using the included Hex key wrench/blade screwdriver, unscrew the sprocket/chain end cover nuts to remove the sprocket/chain end cover (Fig. 17).

5. Starting at the tip, mount the chain drive links into the bar groove, leaving a loop at the back of the bar. The chain will loosely fit until it is placed on the sprocket (Fig. 20).

9. Lift up the guide bar tip slightly. Use the other end of the hex key wrench/blade screwdriver to turn the chain adjusting screw clockwise to tighten, turn it counterclockwise to loosen (Fig. 6).
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. 23). 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. 23).

bar requires specific experience and special tools. For safety purposes, we recommend you contact an authorized Snow Joe® + Sun Joe® dealer or call the Snow Joe® + Sun Joe® customer service center at 1-866-SNOWJOE (1-866-766-9563).
Sharpening is necessary when:
· The sawdust looks like dust; · Cutting becomes more difficult; · The cut is not straight; · Vibrations increase. An authorized service center will sharpen the chain using the right tools to ensure minimum removal of material and even sharpness on all the cutting edges.
If you sharpen the chain by yourself, it’s recommended to purchase Sun Joe® 24V-CSSHRP-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® + Sun Joe® 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. 24):

Chain Sharpening
mWARNING! To ensure that the saw works safely and
efficiently, it is essential that the cutting components are well-sharpened. It is highly recommended to replace the chain once it loses its ability to cut cleanly and safely. It is possible, however, to sharpen the existing chain if the
sharpening is carefully performed. Any work on the chain and

· 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.

18

· 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. 24).
· 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.
You can purchase replacement parts for your Sun Joe® 24V-10CS-RM cordless chain saw by ordering online at sunjoe.com or, to order by phone, contact Snow Joe® + Sun Joe® customer service at 1-866-SNOWJOE (1-866-766-9563).
