GENERAL POWER TOOL SAFETY WARNINGS

WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below 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 mainsoperated (corded) power tool or battery-operated (cordless) power tool.

1. Work area safety
   a) Keep work area clean and well lit. Cluttered or dark 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 away while operating a power tool. Distractions can cause you to lose control.

2. Electrical safety
   a) 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.
   b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
   c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
   e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
   f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces 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 inattention 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 switch is in the off-position before connecting to power source and/ or 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.
   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 overreach. 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 and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
   g) 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.
   h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

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) Disconnect the plug from the power source and/ or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, 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 and accessories. Check for misalignment or binding 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 bind and are easier to control.
   g) Use the power tool, accessories and tool bits 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.
   h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5. Battery tool use and care
   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 battery pack.
   b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and 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 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.
   e) Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
   f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265 °F (130 °C) may cause explosion.
   g) Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

6. Service
   a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
   b) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

GENERAL CHAIN SAW SAFETY WARNINGS:
a) 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 chain saws may cause entanglement of your clothing or body with the saw chain.
b) 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.
c) Hold the chain saw by insulated gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a “live”wire may make exposed metal parts of the chain saw “live” and could give the operator an electric shock.
d) Wear safety glasses protection. Further protective equipment for hearing, head, hands, legs and feet is recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.
e) Do not operate a chain saw, on a ladder, from a rooftop, or any unstable support. Operation of a chain saw in this manner could result in serious personal injury.
f) Always keep proper footing and operate the chain saw only when standing on fixed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the chain saw.
g) When cutting a limb that is under tension , be alert for spring back. When the tension in the wood fibres is released , the spring loaded limb may strike the operator and/or throw the chain saw out of control.
h) 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.
i) 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 guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
j) Follow instructions for lubricating, chain tensioning and changing the bar and chain. Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
k) Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for cutting metal, plastic, masonry or non-wood building materials.
Use of the chain saw for operations different than intended could result in a hazardous situation.
l) Do not attempt to fell a tree until you have an understanding of the risks and how to avoid them. Serious injury could occur to the operator or bystanders while felling a tree.
m) Do not operate a chain saw in a tree unless you have been specifically trained to do so. Operation of a chain saw in a tree without proper training could increase the risk of serious personal injury.
n) Follow all instructions when clearing jammed material, storing or servicing the chain saw. Make sure the switch is off and the battery pack is removed.
Unexpected actuation of the chain saw while clearing jammed material or servicing may result in serious personal injury.
o) Recommendation that the first-time user should, as a minimum, practise cutting logs on a saw-horse or cradle.
p) Recommendation to have sharpening and maintenance of the saw chain performed by authorised service centres.
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 chain saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:
a) Maintain a firm grip, with thumbs and fingers encircling the chain saw handles, with both hands on the saw and position your body and arm 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.
b) Do not overreach and do not cut above shoulder height.
This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations.
c) Only use replacement bars and chains specified by the manufacturer. Incorrect replacement guide bars and saw chains may cause chain breakage and/or kickback.
d) Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

SAVE THESE INSTRUCTIONS
INSTRUCTIONS CONCERNING THE PROPER TECHNIQUES FOR BASIC FELLING, LIMBING, AND CROSS-CUTTING

1. Felling a tree
   When bucking and felling operations are being performed by two or more persons at the same time, the felling operations 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.
   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.
   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 in Figure 1.Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind direction to judge which way the tree will fall.
   Remove dirt, stones, loose bark, nails, staples and wire from the tree.

2. Notching undercut
   Make the notch 1/3 the diameter of the tree, perpendicular to the direction of falls as illustrated in Figure 1. Make the lower horizontal notching cut (W) first. This will help to avoid pinching either the saw chain or the guide bar when the second notch (X) is being made.

3. Felling back cut
   Make the felling back cut (Y) at least 50 mm higher than the horizontal notching cut as illustrated in Figure 1. Keep the felling back cut parallel to the horizontal notching cut. Make the felling back cut so 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.
   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 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 (Z) to open the cut and drop the tree along the desired line of fall ( 3 ).
   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 ( 2 ). Be alert for overhead limbs falling and watch your footing.

4. Limbing a tree
   Limbing is removing the branches 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 in Figure 2. Branches under tension should be cut from the bottom up to avoid binding the chain saw.

5. Bucking a log
   Bucking is cutting a log 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 the simple directions for easy cutting.
   When the log is supported along its entire length as illustrated in Figure 3, it is cut from the top (overbuck), avoid contacting ground as this will greatly reduce the chain sharpness.When the log is supported on one end, as illustrated in Figure 4, cut 1/3 the diameter from the underside ( underbuck) (1). Then make the finished cut by overbucking (2) to meet the first cut.When the log is supported on both ends, as illustrated in Figure 5, cut 1/3 the diameter from the top (overbuck) (1). Then make the finished cut by underbucking (2) the lower 2/3 to meet the first cut.When bucking on a slope always stand on the uphill side of the log, as illustrated in Figure 6. When “cutting through”, to maintain complete control release the cutting pressure near the end of the cut without relaxing your grip on the chain saw handles. Don’t 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.

SAFETY WARNINGS FOR BATTERY PACK

a) Do not dismantle, open or shred battery pack.
b) Do not expose battery pack to heat or fire. Avoid storage in direct sunlight.
c) Do not short-circuit a battery pack. Do not store battery packs haphazardly in a box or drawer where they may short-circuit each other or be short- circuited by other metal objects.

OPERATING INSTRUCTIONS

NOTE: Before using the tool, read the instruction book carefully.
INTENDED USE
The chainsaw is intended for sawing of trees, tree trunks, branches, wooden beams, planks, etc. Cuts can be sawed with or across the grain. This product is not suitable for sawing mineral materials.
ASSEMBLY

1. MOUNTING THE CHAIN AND SAW BAR
   WARNING: Do not install the battery pack before it has been completely assembled. Always use gloves when handling the chain.

1. Carefully unpack all parts. Turn off the cover chain tension adjustment knob and adjust the saw chain counterclockwise. (See Fig. A1)
2. Place the chainsaw on a level, stable surface.
3. Only use original chains or chains recommended for chainsaws.
4. Insert the chain into the groove around the guide bar. Make sure the chain is in the correct direction of travel by comparing it with the icon chains on the guide bar, or by looking on the chain direction icon on the saw machine.
   Make sure the chain tension panel is facing out. (See Fig. A2)
5. Place the chain on the drive sprocket so that the mounting holes and the two mounting pawls on the chain spacer fall into the grooves in the rail holes. (See Fig. B1, B2)
6. Make sure all parts are installed correctly, and hold the chain and guide bar in horizontal position. Make sure that drive links are fully inserted into drive sprocket (see Fig. C1), no bend as shown in Fig. C2. If there is a bend, take the chain on the guide bar before the bend and pull to straighten it out.
   NOTE: The chain must turn loosely and should not be bent. Chain tension is done as described in the “Chain Tension” section. Now you need check the chain to make sure the tension of chain is installed correctly.
   WARNING: The chain is not yet tensioned.

2. CHAIN TENSION (SEE FIG. D-E3)
   WARNING: New saw chains will stretch.
   Constantly check the chain tension when first use and tighten when the chain stretches around the guide bar.
   WARNING:
   • Removing the battery pack before saw chain tension adjustment.
   • The cutting edges on the chain are very sharp. Use protective gloves when taking the chain.
   • Always maintain the correct tension chains. A loose chain increases the risk returns. A loose chain will fall out from the groove of the guide bar. It may cause injury to the worker and chain damage. Loose chain also will cause rapid wear of the chain, bar and sprocket.

1. Check the chain tension frequently during operation, and tighten when the chain becomes loose around the guide bar.
2. Flip the ring for tool-free lock knob up by hand. Turning it anticlockwise to loosen the chain cover, then tighten the chain tension by turning it clockwise and loosen the chain tension by turning it anti-clockwise until the saw chain is correctly tensioned. Do not tension the chain too tightly. (See Fig. D, E1)
3. The correct chain tension is reached when the chain can be raised approx. 3-5 mm (using a small amount of force) from the guide bar in the centre. (See Fig. E2)
   Chain direction:
   The cutting teeth of the chain must be pointing forward on the top of the blade. Ensure the chain is in correct running direction. (See Fig. E3)

3. LUBRICATION (SEE FIG. F)
   NOTE: Chain life and cutting capacity depend on optimum lubrication. Therefore, the chain is automatically oiled during operation.
   NOTE: The chainsaw is not supplied filled with oil. It is essential to fill with oil before use. Operating the chainsaw without chain oil or when the oil level is below the minimum mark will result in damage to the chainsaw.
   Please use only biologically-based chainsaw oil, i.e. oil which is 100% biologically decomposable.
   Biological chainsaw oil should be available everywhere at your local specialist dealer.
   Do not use old oil! This will damage the chainsaw.
   a. Set chainsaw on any suitable surface with oil tank cap facing upward.
   b. Clean area around the oil tank cap with a cloth, and unscrew the cap by turning it counter-clockwise.
   c. Fill the oil tank with 180ml of specialist chain oil (not supplied, available to purchase separately) and keep oil topped up during use.
   d. Avoid dirt or debris entering oil tank. Refit oil tank cap and tighten by turning clockwise until hand tight.
   NOTE: Oil tank and oil bubbles need to be cleaned after each use or before long-term storage.
   • Unscrew the oil filler cap of the oil tank and pour out the remaining oil in the oil tank.
   • Remove the chain cover, dismantle the chain and guide bar.
   • Manually flip the chain guard to the maximum position 3-5 times, squeeze out the remaining oil in the oil bubble.
   CAUTION: Do not face people at the oil outlet!
   In addition, before each use, after filling the oil tank with oil, you need to manually flip the chain guard to the maximum position once to ensure that oil is stored in the oil bubble.

4. TO REMOVE OR INSTALL BATTERY PACK (SEE FIG. G)
   Depress the battery pack release button to release and slide the battery pack out from your tool. After recharge, slide it back into your tool. A simple push and slight pressure will be sufficient.

OPERATION

1. CHARGE YOUR BATTERY PACK (SEE FIG. H)

2. CHECKING THE BATTERY POWER CONDITION
   5 LED lights show the battery power condition. Before starting or after use, press the button beside the lights to check the battery power condition.

3. HOLDING AND CONTROL OF THE SAW (SEE FIG. I)
   Hold and operate the chain saw so that one hand is on the grip area with a large finger around this area.

4. SWITCHING ON AND OFF (SEE FIG. J)

1. Take the guide bar cover off. Place the chainsaw on a flat place.
2. Install the battery pack.
3. For switching on, press the lock-off button, then fully press the on/off switch and hold in this position. The lock-off button can now be released. (See Fig. J)
4. For switching off, release the on/off switch, or push the hand guard forward to engage it.

5. CUTTING
   WARNING: Check oil level gauge prior to starting and regularly during operation. Refill chain oil (not supplied) when oil level is low.
   WARNING: Check the chain tension approx. every 10 minutes during operation.
   WARNING: Always wear safety goggles, ear protection, protective gloves and heavy-duty work clothes during operation.
   WARNING: Check the automatic lubrication as described above.

1. Installing the battery pack into the machine.
2. Make sure section of log to be cut is not laying on the ground. This will keep the chain from touching the ground as it cuts through the log. Touching the ground while the chain is moving is dangerous and will dull the chain.
3. For switching on, press the lock-off button, then fully press the on/off switch and hold in this position. The lock-off button can now be released. (See Fig. J)
4. Make sure your footing is firm. Keep feet-shoulder width apart. Distribute your weight evenly on both feet.
5. When ready to make a cut, push the lock-off button completely in with the right thumb and squeeze the trigger.
   This will turn saw on. Releasing the trigger will turn the saw off. Make sure the saw is running at full speed before starting a cut.
6. When starting a cut, slowly place moving chain against the wood. The wood should be as close to the saw body as possible. Hold saw firmly in place to avoid possible bouncing or skating (sideways movement) of saw.
7. Guide the saw using light pressure and do not put excessive force on the saw, letting the saw do its work. The motor will overload and can burn out. It will do the job better and safer at the rate for which it was intended.
8. Remove the saw from a cut with the saw running at full speed. Stop the saw by releasing the On/off Switch. Make sure the chain has stopped before setting the saw down.
9. Keep practicing on scrap logs in a secure working area until you are comfortable, using a fluid motion and a steady cutting rate.
10. After working with the chainsaw, you should always: remove the battery pack, clean the saw chain and guide bar and replace the guide bar cover.

6. KICKBACK SAFETY DEVICES ON THIS SAW
   This saw has a low-kickback chain and reduced kickback guide bar. Both items reduce the chance of kickback. However, kickback can still occur with this saw.
   The following steps will reduce the risk of kickback.
   • Keep all safety items in place on saw. Make sure they work properly.
   • Do not overreach or cut above shoulder height.
   • Keep solid footing and balance at all times.
   • Stand slightly to the left side of saw. This keeps your body from being in direct line with chain.
   • Do not let guide bar nose touch anything when chain is moving.
   • Never try cutting through two logs at same time. Only cut one log at a time.
   • Do not bury the guide bar nose or try plunge cut (boring into wood using guide bar nose).
   • Watch for shifting of wood or other forces that may pinch chain.
   • Use extreme caution when reentering a previous cut.
   • Use only the low-kickback chain and guide bar that were supplied with this chainsaw or recommended replacements.
   • Never use a dull or loose chain. Keep chain sharp with proper tension.

7. HOW TO USE SAW SAFELY

1. Use the chainsaw only with secure footing.
2. Hold the chainsaw at the right-hand side of your body (See Fig. K).
3. The chain must be running at full speed before it makes contact with the wood.
4. Use the shock absorber teeth to fix the saw to the tree before starting cutting.
5. Use shock absorber teeth as leverage during cutting. (See Fig. L)
6. Raise the chain guard when cutting material down up. (See Fig. M)
7. Do not operate the chainsaw with arms fully extended, attempt to saw areas which are difficult to reach, or stand on a ladder while sawing. (See Fig. N)
   WARNING: Never use the chainsaw above shoulder height.

8. CUTTING WOOD UNDER TENSION (SEE FIG. O)
   WARNING: Use extreme caution when you cut branches under tension. Be prepared for situations where the branch might bounce. When the tension in the wood is reduced, branches can spring back and stab workers, resulting in serious injury or death.
   When sawing logs supported by both ends, start the cut at the top (Y) about 1/3 the diameter of the log and finish the cut (Z) from below to prevent the saw from touching the ground. When sawing a log supported by only one end, start at the bottom (Y) and cut about 1/3 of the log diameter and finish cutting the top (Z) to avoid splitting the log or getting a chainsaw pinch.

MAINTENANCE AND CARE

1. Remove the battery pack from the chainsaw
   • When not in use
   • Before moving from one place to another
   • Before servicing
   • Before changing accessories or attachments, such as saw chain and guard

2. Inspect chainsaw before and after each use. Check saw closely if guard or other part has been damaged. Check for any damage that may affect operator safety or operation of saw. Check for alignment or binding of moving parts. Check for broken or damaged parts. Do not use chainsaw if damage affects safety or operation. Have damage repaired by authorized service center.

3. Maintain chainsaw with care.
   • Never expose saw to rain or direct moisture.
   • Keep chain sharp, clean, and lubricated for better and  safer performance.
   • Keep handles dry, clean, and free of oil and grease.
   Keep all screws and nuts tight.

4. When servicing, use only identical replacement parts.

5. When not in use, always store chainsaw
   • in a high or locked place, out of children’s reach
   • in a dry place
   • with guide bar cover in place

Bar maintenance
To maximize bar life, the following bar maintenance is recommended.
The bar rails that carry the chain should be cleaned before storing the tool or if the bar or chain appear to be dirty.
The rails should be cleaned every time the chain is removed.

To clean the bar rails

1. Remove chain cover and bar and chain.
2. Using a wire brush, screwdriver or similar tool, clear the residue from the inner groove of the bar. (See Fig. P)
3. Make sure to clean oil passages thoroughly.

Conditions which require chain and guide bar maintenance:

• Saw cuts to one side or at an angle.
• Saw has to be forced through the cut.
• Inadequate supply of oil to the bar and chain.

Check the condition of the guide bar each time the chain is sharpened. A worn guide bar will damage the chain and make cutting difficult.
After each use, remove the battery pack from the chainsaw, clean all sawdust from the guide bar and drive sprocket hole. When rail top is uneven, use a flat file to restore square edges and sides.
Replace the guide bar when the groove is worn, the guide bar is bent or cracked, or when excess heating or burring of the rails occurs. If replacement is necessary, use only the guide bar specified for your saw in the spare parts list.

Lubricate drive sprocket
WARNING: Remove the the battery pack from the chainsaw before performing any service or maintenance on this tool.
WARNING: Wear heavy duty gloves when performing any maintenance or service to this tool.
NOTE: It is not necessary to remove the chain or bar when lubricating the drive sprocket.

1. Clean the bar and drive sprocket.
2. Using a grease gun, insert the tip of the gun into the lubrication hole (b) and inject grease until it appears at the outside edge of the drive sprocket tip. (See Fig. Q)
3. To rotate the drive sprocket pull the chain by hand until the ungreased side of the drive sprocket is in line with the grease hole. Repeat the lubrication procedure.

General maintenance
WARNING: Before inspecting, cleaning or servicing the unit, wait for all moving parts to stop, and remove the the battery pack from the chainsaw. Failure to follow these instructions can result in serious personal injury or property damage.
WARNING: When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. To ensure safety and reliability, all repairs should be performed by a qualified service technician.
Follow maintenance instructions in this manual. Proper cleaning of saw and chain and guide bar maintenance can reduce chances of kickback.
Inspect and maintain saw after each use. This will increase the service life of your saw.
NOTE: Even with proper sharpening, risk of kickback can increase with each sharpening. It is therefore recommended to replace saw chain instead of sharpening to minimise risk of kickback.
After each use of chainsaw, clean the plastic parts of the saw using a damp cloth with a mild detergent.
Do not use any strong detergents on the plastic housing or the handle. They can be damaged by certain aromatic oils, such as pine and lemon, and by solvents such as kerosene. Moisture can also cause a shock hazard. Wipe off any moisture with a soft dry cloth.
Storing the machine
Remove the the battery pack from the chainsaw.
Wear heavy gloves to clean the tool thoroughly.
Store the tool in a dry, well-ventilated area, locked-up or up high, out of the reach of children. Do not store the machine on or adjacent to fertilizers, gasoline, or other chemicals.
For battery tools
The ambient temperature range for the use and storage of tool and battery is 32ºF -113ºF (0ºC-45ºC).
The recommended ambient temperature range for the charging system during charging is 32oºF -104ºF (0ºC-40ºC).
