Chain Saw Safety Warnings

General Chain Saw Safety Warnings

1. 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.

2. 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 aft personal injury and should never be Dane.

3. 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 aft the chain saw “live” and could give the operator an electric shack.

4. 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.

5. Do not operate a chain saw in a tree, on a ladder, from a rooftop, or any unstable support. Operation aft a chain saw in this manner could result in serious personal injury.

6. 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 are control of the chain saw.

7. When cutting a limb that is under tension, be alert for spring back. When the tension in the wood fibers is released, the spring loaded limb may strike the operator and/are throw the chain saw aut of control.

8. Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you are pull you aft balance.

9. 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 like lahara daft accidental contact with the moving saw chain.

10. 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.

11. 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.

12. 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.

13. 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.

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

1. 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.
2. 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.
3. 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.
4. Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

Vibration and noise reduction
To reduce the impact of noise and vibration emission, limit the time of operation, use low-vibration and low-noise operating modes as well as wear personal protective equipment (PPE).
Take the following points into account to minimize the vibration and noise exposure risks

• Only use the chain saw as intended by its design and these instructions.
• Ensure that the chain saw is in good condition and well maintained.
• Use correct attachments for the chain saw and ensure they are in good condition.
• Keep a tight grip on the handles/gripping surfaces.
• Maintain the chain saw in accordance with these instructions and keep it well lubricated (where appropriate).
• Plan the work schedule to spread any high vibration tool use across a longer period of time.

Residual risks
Even if you are operating this chain saw in accordance with all the safety requirements, potential risks of injury and damage remain. The following dangers can arise in connection with the structure and design of this chain saw

• Health defects resulting from vibration emission if the chain saw is used over long periods of time or not adequately managed and properly maintained.
• Injuries and damage to property due to broken attachments or the sudden impact of hidden objects during use.
• Risk of injury and property damage caused by flying objects.
• Risk of getting entangled by the chain saw’s motor.
• Risk of inhaling small dust and particles into the lungs.

Kickback

WARNING Risk of injury!

• Beware of kickback. Kickback can lead to dangerous loss of control of the machine and result in serious or fatal injury to the operator or anyone standing close by.
• With a basic understanding of “kickback”, the element of surprise can be reduced or eliminated. Sudden surprise contributes to the majority of accidents.
• Keep a good firm grip on the machine with both hands, the right hand on the rear handle (8) and the left hand on the front handle (5), when the machine is running. Maintain a firm grip with your thumbs and fingers encircling the handles. A firm grip will help you reduce “kickback” and maintain control of the machine.
• Rotational kickback occurs when the tip or the nose sprocket of the guide bar (2) touches an object, and linear kickback occurs if wood pinches the machine in the cut (Fig. 23).

To avoid kickback

• Saw with guide bar (2) at a flat angle.
• Always ensure correct chain tension. Never work with a loose, widely stretched or the heavily worn out saw chain (3).
• Ensure the saw chain (3) is sharpened correctly. Follow manufacturer’s sharpening and maintenance instructions for the saw chain (3).
• Do not let the tip or nose sprocket of the guide bar (2) contact a log, branch, or any other obstruction which could be hit while operating the machine.

Freeing a trapped machine
If the machine becomes trapped or jammed during cutting, operators should

1. Switch the machine off and attach it securely to the tree inboard (i.e. towards the trunk side) of the cut or to a separate tool line.
2. Pull the machine from the kerf while lifting the branch as necessary.
3. Use a handsaw or second chain saw to release the trapped machine by cutting a minimum of 12 inch (30 cm) away from the trapped machine. The release cuts should always be outboard (toward the tips of the branch).

Felling a tree

WARNING Risk of injury!

• Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous weather has ended.
• Do not fell trees that lean at extreme angles or large trees with rotten limbs, loose bark, or hollow trunks. Instead, have these trees pushed or dragged down with heavy equipment and then cut them up.
• Do not fell trees near electrical wires or buildings.
• Check the tree for damaged or dead branches that could fall and hit you during felling.
• Periodically glance at the top of the tree during the back cut to assure the tree is going to fall in the desired direction.
• If the tree starts to fall in the wrong direction, or if the machine gets caught or hung up during the fall, leave the machine and save yourself.

Preparation for tree felling

• When bucking and felling operations are being performed by two or more persons 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 utility company should be notified immediately.
• The operator should stand on the uphill side of the terrain, as the tree is likely to roll or slide downhill after it is felled.
• Before any cuts are started, pick your escape route (or routes, in case the intended t The operator should stand on the uphill side of the terrain, as the tree is likely to roll or slide downhill after it is felled.
• Before any cuts are started, pick your escape route (or routes, in case the intended
• 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 where felling cuts are to be made.

Notching undercut
Make the notch 1 /3 the diameter of the tree, perpendicular to the direction of fall (Fig. 25).

NOTICE I Make the lower horizontal notching cut first. This will help to avoid pinching of either the saw chain (3) or the guide bar (2) when the second notch is being made.

Felling back cut

1. Make the felling back cut at least 2″ (SO mm) higher than the horizontal notching cut (Fig. 26). 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 (Fig. 26) wood keeps the tree from twisting and falling in the wrong direction. Do not cut through the hinge.
2. 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 (3), stop cutting before the felling back cut is complete and use wedges of wood, plastic or aluminum to open the cut and drop the tree along the desired line of fall.
3. When the tree begins to fall remove the machine from the cut, stop the motor, put the machine down, then use the retreat path planned. Be alert for overhead limbs falling and watch your footing.

Lambing and pruning

WARNING Risk of injury!

• Most kickback accidents happen during lambing. Be cautious and avoid contacting the log or other limbs with the tip of the guide bar (2).
• Only prune the limbs below chest height. Do not climb into a tree to limb or prune.
• Do not stand on ladders, platforms, logs, or in any position which may cause you to lose the balance or control of the machine.
• When pruning trees, it is important not to make the flush cut next to main limb or trunk until you have cut off the limb further out to reduce the weight. This prevents stripping the bark from the main member.
• Lambing is removing the branches from a fallen tree. When lambing, leave larger lower limbs to support the log off the ground. Remove the small limbs in one cut (Fig. 27). Branches under tension should be cut from the bottom up to avoid binding the machine.

Bucking a log

WARNING Risk of injury!

• Keep a clear cutting area. Make sure that no objects can contact the tip of the guide bar (2) during cutting.
• Always maintain complete control when cutting through the material. Release the cutting pressure near the end of the cut without relaxing the grip on the handles.
• Do not allow the saw chain (3) to contact the ground.
• After completing the cut, stop the machine and wait for the saw chain (3) to stop completely before moving the machine. Always stop the motor before moving from tree to tree.

NOTICE

• When overbulking, begin on the top side of the log with the bottom of the machine against the log (Fig. 28); exert light downward pressure. The machine  tends to pull away from you.
• When under bucking, begin on the underside of the log with the top of the machine  against the log (Fig. 28); exert light upward pressure. The machine tends to push back at you.
• 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.
• When the log is supported along its entire length, it is cut from the top (Fig. 29).
• When the log is supported on one end, cut 1/3 the diameter from the underside. Then make the final cut by overbucking to meet the first cut (Fig. 30).
• When the log is supported on both ends, cut 1/3 of that diameter from the top overbuck. Then make the final cut by underbucking the lower 2/3 to meet the first cut (Fig. 31 ).
• When bucking on a slope, always stand on the uphill side of the log (Fig. 32).

WARNING Risk of injury!
Take the battery pack of the machine before cleaning, maintenance, storage, or transportation.

NOTICE I Do not immerse the machine in water or other liquids. Never hold the machine under running water.

Cleaning the housing

• Clean the outer housing with damp, lint-free cloth. Wipe dry after cleaning.
• Unclog the ventilation openings (16) with a soft brush if needed.
• Never use corrosive detergents, wire brushes, abrasive scourers, metal or sharp utensils to clean the machine.

Cleaning the saw chain

• Use a soft plastic brush to clean the saw chain (3) from dirt.
• Use a resin solvent (not provided) to clean the saw chain (3). Read the resin solvent manufacturer’s instructions before proceeding.
• To protect the saw chain from rusting and oxidation, lubricate it with a special saw chain oil (not provided) after cleaning.

Cleaning the guide bar

• Disassemble the guide bar (2) and saw chain in reversed order from assembly. Remove any dirt accumulated on the edge of the guide bar (2) using a plastic putty knife (not provided).
• Use a damp, lint-free cloth to clean the surface.
• Wipe the surface with a dry cloth afterwards.

Storage

• Clean the machine before storage.
• Empty the oil tank (12) and dispose of the used chain oil in accordance with local regulations.
• Lubricate slightly the saw chain (3) and the sprockets on the guide bar (2) before any long-term storage to prevent rusting and oxidation.
• Fit the guide bar cover (17) on the guide bar (2).
• Store the machine in a dry area. Keep away from children and pets.
• The wall mount holder (18) is used for hanging the machine. Securely mount the wall mount holder (18) levelly on a wall using 2 screws (not included). Hang the machine onto the wall mount holder (18) (Fig. 33).

NOTICE I Before mounting, determine the suitable mounting location. The wall mount holder (18) must be fixed to a wooden or masonry/concrete wall using fasteners that are appropriate for the mounting surface. Do not install on drywalls, wall boards or thin plywood. The mounting surface must be capable of supporting the combined weight of the machine and the battery pack.

Transport

• Engage the chain brake and take the battery off the machine before transporting the machine.
• Empty the oil tank (12) and dispose of the used chain oil in accordance with local regulations.
• Fit the guide bar cover (17) on the guide bar (2) during transportation.
• Only carry the machine in a horizontal position. Grip the front handle (S) in a manner that the machine is balanced horizontally
• Secure the machine when transporting in a vehicle to prevent turnover, fuel spillage and damage to the machine. Use line or ratchet tie-down if necessary.

Maintenance

WARNING Risk of injury!
Maintenance performed by unauthorized personnel may result in misplacing of internal wires and components which could cause a serious injury.

Any other servicing than mentioned in this manual should be performed by a professional repair center.

Guide bar and saw chain maintenance

CAUTION Risk of injury!
Always wear protective gloves when handling the saw chain (3). The components of the saw chain (3) are sharp and may contain burrs.

NOTICE I Regularly check the condition of the drive sprocket. If it is worn or damaged due to strain, have it replaced by professional repair center. Do not mount a new saw chain onto a worn drive sprocket.

1. Disassemble the guide bar (2) and saw chain (3) in reversed order from assembly.
2. Check the oiling port for clogging and clean if necessary to ensure proper lubrication of the guide bar (2) and saw chain (3) during operation. Use a soft wire small enough to insert into the oil discharge hole.
3. Remove any dirt accumulated inside the guide bar (2) slots using a plastic putty knife (not provided).
4. Check the guide bar “rail” for wear: Hold a ruler (straight edge) against the side of the guide bar (2) and “cutter side plates”. If there is a gap between the ruler and guide bar (2) the guide bar “rail” is normal. If there is no gap (ruler flush against the side of the guide bar (2)) the guide bar “rail” is worn and needs to be replaced with a new one of the same type (Fig. 34).
5. Clean the nose sprocket at the tip of the guide bar (2).
6. Refit the saw chain (3) and the guide bar (2) as described in “Assembly”.
7. Using a disposable lube gun, insert the needle nose into the lubrication hole (1)(Fig. 35). Inject grease until it appears at the outside edge of the sprocket.
8. Make sure that the chain brake is disengaged. Rotate the saw chain (3) by hand. Repeat the lubrication procedure until the entire sprocket has been greased.

Saw chain sharpening

WARNING Risk of injury!

• Improper chain sharpening increases the potential of kickback.
• Failure to replace or repair a damaged chain can cause serious injury.
• If cutter teeth on the saw chain have hit hard objects, such as nails and stones, or have been abraded by mud or sand on the wood, have the saw chain sharpened by a professional repair center.

NOTICE

• A properly sharpened saw chain cuts through wood effortlessly, even with very little pressure. Never use a dull or damaged saw chain. A dull saw chain cutter leads to increased physical strain, increased vibration load, unsatisfactory cutting results and increased wear.
• For smooth and fast cutting, the saw chain needs to be maintained properly. The saw chain requires sharpening when the wood chips are small and powdery, the machine must be forced through the wood during cutting, or the machine cuts to one side.
• Be sure to file all cutters to the specified angles and to the same length, as fast cutting can be obtained only when all cutters are uniform.
• Occasionally remove filings from the file with a wire brush (not included).

1. Properly tension the saw chain (3) prior to sharpening.
2. Using a 4 mm diameter round file (not included), perform the filing at the middle position of the guide bar (2) by hand.
3. Keep the file level with the top plate of the cutting tooth. Do not let the file dip or rock.
4. Keep a correct sharpening angle of 30° between the file and the saw chain (3) (Fig. 36).
5. Using light but firm pressure, perform a stroke towards the front corner of the tooth.CLift the file away from the steel on each return stroke.
6. Make a few firm strokes on every tooth. File all left-hand cutters in one direction. Then move to the other side and file the right-hand cutters in the opposite direction (Fig. 37).
7. Check the depth gauge clearance every time the saw chain is filed. Use a flat file and a depth gauge jointer (not included) to lower all gauges uniformly. The depth gauge should be maintained at a clearance of 0.025″ (0.6 mm) (Fig. 38).
