1.2 OVERVIEW

2. GENERAL POWER TOOL

SAFETY WARNINGS

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

Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your battery operated (cordless) power tool.

2.1 WORK AREA SAFETY

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

2.2 ELECTRICAL SAFETY

• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

2.3 PERSONAL SAFETY

• 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 lapse of attention while operating power tools may result in serious personal injury.

• Use personal protection. Always wear eye protection.
  Protective products such as dust mask, non-skid safety shoes, hard hat or hearing protection used appropriately will reduce personal injuries.

• Prevent unintentional starting. Ensure the switch is in the off position before connecting to power source and/or battery pack and when picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.

• 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.

• Do not over-reach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

• 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.

• 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.

• 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.

2.4 POWER TOOL USE AND CARE

•  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.

• 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.

• Disconnect the plug from the power source and/or the battery pack 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.

• 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.

• Maintain power tools. 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.

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

• 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.

2.5 BATTERY TOOL USE AND CARE

• 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.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• 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 fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with plenty of soap and water. If liquid contacts eyes, immediately seek medical help. Liquid ejected from the battery may cause irritation or burns.

2.6 SERVICE

• 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.

3. CHAINSAW SAFETY WARNINGS

• Keep all parts of the body away from the saw chain when the chainsaw is operating. Before you start the chainsaw, make sure the saw chain is not in contact with anything. A moment of inattention while operating chainsaws may cause entanglement of your clothing or body with the saw chain.

• Always hold the chainsaw with your right hand at the rear handle and your left hand at the front handle.
  Holding the chainsaw 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 parts of the power tool “live” and could give the operator an electric shock.

• Wear safety glasses and hearing protection. Further protective product for head, hands, legs and feet is recommended. Adequate protective clothing will reduce personal injury from flying debris or accidental contact with the saw chain.

• Do not operate a chainsaw in a tree. Operation of a chainsaw while up in a tree may result in personal injury.

• Always keep proper footing and operate the chainsaw only when standing on fixed, secure and level surface.
  Slippery or unstable surfaces such as ladders may cause loss of balance or control of the chainsaw.

• When cutting a limb that is under tension, be alert of spring back. When the tension in the wood is released, the spring loaded limb may strike the operator and/or throw the chainsaw 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 chainsaw by the front handle with the chainsaw switched off and away from your body.
  When transporting or storing the chainsaw, always fit the guide bar cover. Proper handling of the chainsaw will reduce the likelihood of accidental contact with the moving saw chain.

• Follow instructions for lubricating, chain tensioning and changing accessories. Improperly tensioned or 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, causing loss of control.

• Cut wood only. Do not use chainsaw for purposes not intended. For example: do not use chainsaw for cutting plastic, masonry or non-wood building materials. Use of the chainsaw for operations other than intended could result in a hazardous situation.

4. PREVENT OPERATOR 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 chainsaw 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, with thumbs and fingers encircling the chainsaw handles, with both hands on the saw and your body and arm positioned 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 chainsaw.

•  Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chainsaw in unexpected situations.

• Only use replacement bars and chains specified by the manufacturer. Incorrect replacement bars and chains may cause chain breakage and/or kickback.

• Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.
  Decreasing the depth gauge height can lead to increased kickback.

10.6 FELL A TREE

Recommendation that the first-time user should, as a minimum practice, start cutting logs on a saw-horse or cradle.
Before you start to fell a tree, make sure that

• The minimum distance between the areas of bucking and  felling is two times the height of the tree.
• The operation does not
• Cause injury to personnel.
• Hit utility lines. If the tree touches utility lines, immediately tell the utility company.
• Cause losses in property.
• The user is not in the danger area (24), for example, the downhill side of the area.
• The escape paths (25) that extend back and diagonally behind the felling direction (23) are clear. The felling direction is controlled by
• The natural lean of the tree.
• The location of larger branches.
• The wind direction.
• Ensure there is no dirt, stones, loose bark, nails, and staples on the tree.

1. Make a lower level notching cut (27). Make sure that this cut is

a) 1/3 wide of the diameter of the tree.
b) Perpendicular to the felling direction.

CAUTION
The level notching cut helps prevent pinching of the saw chain or the guide bar when you make the second notch.

2. Make the felling cut no less than 2 in. (50 mm) and higher than the level notching cut. Make sure that this cut
a) Is parallel to the level notching cut.
b) Keeps sufficient wood to become a hinge (29) which prevents the tree from twisting and felling in the wrong direction.
When the felling cut (28) gets near the hinge (29), the tree falls. Stop the felling cut if the tree

• Does not fall in the correct direction or
• Moves backwards, causing the cutting bar and chain to become stuck in the cut.

3. Use felling wedge to open the cut and let the tree fall in the correct direction.

4. When the tree starts to fall,
a) Remove the chainsaw from the cut.
b) Stop the machine.
c) Put the machine down.
d) Move away from the tree via the escape path (25).

Always keep watching the tree to see it’s direction of  fall, be careful with overhead branches and your footing.

10.7 LIMB A TREE

Limbing is the removal of the branches from a fallen tree.

1. Keep the larger lower branches to hold the log off the ground (31).
2. Remove the small limbs (30) in one cut.
3. Limb the branches with tension from the bottom to top.
4. Keep the larger lower branches as a support until the log is limbed.

10.8 BUCK A LOG

To buck is to cut a log into lengths.

CAUTION
Do not let the chain saw touch the ground.

It is important to make sure your footing is secure and your weight is evenly distributed. If possible, lift the log and hold it with branches, logs or chock. Obey the instructions below:

When the log is held along the full length (32), cut it from the top (33).

When the log is held on one end (34),

1. Cut the first time 1/3 of the diameter from the bottom (35).
2. Cut the second time from the top (36) to complete the bucking.

When the log is held on two ends (37),

1. Cut the first time 1/3 of the diameter from the top (36).
2. Cut the second time lower 2/3 from the bottom to complete the bucking (35).

When the log is on a slope,

1. Stand on the uphill side.
2. Control the chain saw completely.
3. Hold the chain saw handles tightly.
4.  Release the cutting pressure near the end of the cut.

When bucking is complete (38),

1. Wait for the chain to stop (39).
2. Ensure the chainsaw is turned off.
3. Check for hazards before you move to another tree.

11. MAINTENANCE

CAUTION
Do not let brake fluids, gasoline, petroleum-based materials touch the plastic parts. Chemicals can cause damage to the plastic, and make the plastic unserviceable.

3. Turn the chain adjustment screw clockwise to increase the chain tension.

4. Turn the chain adjustment screw counterclockwise to decrease the chain tension.

11.3 SHARPEN THE CUTTERS

Sharpen the cutters if it is not easy for the chain to go into the wood.

NOTE
We recommend that a service center, which has an electric sharpener, perform important sharpening work.

1. Tensioning chain.
   

2. Sharpen the cutters corner with a 5/32 in. (4 mm) diameter round file.
   

3. Sharpen the top plate, side plate and depth gauge with a flat file.
   

4. File all the cutters to the specified angles and the same length.

NOTE
During the process,

• Keep the file flat with the surface to be sharpened.
• Use the midpoint of the file bar.
• Use light but firm pressure when sharpening the surface.
• Lift the file away on each return stroke.
• Sharpen the cutters on one side and then move to the other side.

Replace the chain if:

• The length of the cutting edges is less than 1/5 in. (5 mm).
• There is too much space between the drive links and the rivets.
• The cut speed is slow
• Sharpening the chain many times but it does not increase the cutting speed. The chain is worn.

11.4 GUIDE BAR MAINTENANCE

NOTE
Make sure that it is turned over periodically to keep symmetrical wear on the bar.

1. Lubricate the bearings on the nose sprocket (if present) with the syringe (not included).
2. Clean the bar groove with the scraping hook (not included).
3. Clean the lubrication holes.
4. Remove burr from the edges and level the cutters with a flat file.

Replace the bar if:

• The groove does not fit with the height of the drive links (which must never touch the bottom).
•  The inside of the guide bar is worn and makes the chain lean to one side.
