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 mains-operated (corded) power tool or 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

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

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 moment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
• 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.
• 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 overreach. 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 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.

• 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 and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools 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 water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
• 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.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130°C (265 °F) may cause explosion.
• 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.

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.
• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

SAFETY INSTRUCTIONS FOR CHAIN SAWS

3.1 GENERAL 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 chain saws 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 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 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.

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

• 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.

• 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.

• 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.

• 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 chainsaw 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• It is only to be used in an outdoor, domestic application by adults.

• Do not use the chainsaw for any purpose not listed above.

• It is not to be used by children or by persons not wearing adequate personal protective equipment and clothing.

• This appliance is not intended for use by persons with reduced physical, sensory or mental capabilities or lack of experience or knowledge, unless they have been given supervison or instruction concerning use of the appliance by a person responsible for their safety.

3.2 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 chainsaw 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:

• Maintain a firm grip, with thumbs and fingers encircling the chainsaw 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 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 guide bars and saw chains specified by the manufacturer. Incorrect replacement guide bars and saw 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.

9.6 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.

9.7 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.

9.8 BUCK A LOG
To buck is to cut a log into lengths.
CAUTION
Do not let the chainsaw 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 (35) to complete the bucking.

When the log is on a slope:

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

When bucking is complete:

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

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.
CAUTION
Do not use strong solvents or detergents on the plastic housing or components.
WARNING
Remove the battery pack from the machine before maintenance.
10.1 ADJUST THE CHAIN TENSION
The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.
Tension the chain so that it can only just be pulled away from the bar at its center point.
WARNING
A slack chain may jump off and cause serious or even fatal injury.
CAUTION**
Wear protective gloves if you touch the chain, bar or areas around the chain.

1. Stop the machine.

2. Loosen the chain cover by turning the chain cover knob counterclockwise. **NOTE**
   It is not necessary to remove the chain cover to adjust the chain tension.

3. Turn the chain tension knob clockwise to increase the chain tension.

4. Turn the chain tension knob counterclockwise to decrease the chain tension.

5. When the chain is at the wanted tension, tighten the chain cover.

NOTE
During normal saw operation, the temperature of the chain increases. The drive links of a correctly tensioned warm chain will hang approximately 1/16 in. (1.58 mm) out of the bar groove.

10.2 SHARPEN THE CUTTERS
Sharpen the cutters if chain does not go into wood easily.
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.

10.3 GUIDE BAR MAINTENANCE

NOTE
Make sure that the bar 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.

TRANSPORTATION AND STORAGE
