Safety Instruction for Pruning Saw

WARNING: Drilling, sawing, sanding or machining wood products can expose you to wood dust, a substance known to the State of California to cause cancer. Avoid inhaling wood dust or use a dust mask ? or other safeguards for personal protection. For more information go to www.P65Warnings.ca.gov/wood.

a) Keep all parts of the body away from the saw chain when the pruning saw is operating. Before you start the pruning saw, make sure the saw chain is not contacting anything. A moment of inattention while operating pruning saws may cause entanglement of your clothing or body with the saw chain.

b) Always hold the pruning saw with your one hand on the Grip Area (6) and your other hand on the Secondary Grip Area (3). Holding the pruning saw improperly increases the risk of personal injury and should never be done.

c) Hold the pruning 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 pruning 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 pruning saw in a tree, on a ladder, from a rooftop, or any unstable support. Operation of a pruning saw in this manner could result in serious personal injury.

f) Always keep proper footing and operate the pruning saw only when standing on fixed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the pruning saw.

g) 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/or throw the pruning 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 pruning saw with the pruning saw switched off ⚙️ and away from your body. When transporting or storing the pruning saw, always fit the guide bar cover. Proper handling of the pruning 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 pruning saw for purposes not intended. For example: do not use pruning saw for cutting metal, plastic, masonry or non-wood building materials. Use of the pruning saw for operations different than intended could result in a hazardous situation.

l) This pruning saw is not intended for tree felling. Use of the pruning saw for operations different than intended could result in serious injury to the operator or bystanders.

m) Follow all instructions when clearing jammed material, storing or servicing the pruning saw. Make sure the switch ⚙️ is off and the battery pack ? is removed. Unexpected actuation of the pruning saw while clearing jammed material or servicing may result in serious personal injury.

n) Recommendation that the first-time user should, as a minimum, practice cutting logs on a saw-horse or cradle.

o) Recommendation to have sharpening and maintenance of the saw chain performed by authorized service centers.

Causes and Operator Prevention of Kick-Back

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.

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 pruning saw or recommended.
• Never use a dull or loose chain. Keep chain sharp with proper tension.

How to Use Saw Safely

a) Use the pruning saw only with secure footing.

b) Hold the pruning saw at the right-hand side of your body (See Fig. K).

c) The Chain must be running at full speed before it makes contact with the wood.

d) Use the Cutting base panel to secure the saw onto the wood before starting to cut.

e) Use the Cutting base panel as a leverage point while cutting. (See Fig. L)

f) Raise the Chain Guard when cutting from bottom to top of material. (See Fig. M)

g) Do not operate the saw with arms fully extended, attempt to saw areas which are difficult to reach, or stand on a ladder while sawing. (See Fig. N)

Cutting Wood Under Tension

WARNING: When cutting a limb that is under tension, use extreme caution. Be alert for wood springing back. When wood tension is released, limb could spring back and strike operator causing severe injury or death.

When sawing logs supported on both ends, start the cut from above (Y) about 1/3 of the diameter into the log (overbuck) and then finish the cut (Z) from below, in order to avoid contact of the electric chain saw with the ground. When sawing logs supported on only one end, start the cut from below (Y) about 1/3 of the diameter into the log (underbuck) and finish the cut from above (Z) in order to avoid log splitting or jamming of the electric chain saw.

Diagram illustrating cutting wood under tension with points Y and Z indicating cut start/finish points.

Saw Maintenance

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.

Maintenance and Storage of Electric Chain Saw

• Remove the battery pack ?: When not in use, Before moving from one place to another, Before servicing, Before changing accessories or attachments, such as saw chain and guard.
• Inspect electric chain saw 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 electric chain saw if damage affects safety or operation. Have damage repaired by authorized service center.

• When servicing, use only identical replacement parts.
• When not in use, always store electric chain saw in a high or locked place, out of children's reach, in a dry place, with Bar and Chain 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 Housing-Cover, Bar and Chain. (see section ASSEMBLY)
2. Using a wire brush, screwdriver or similar tool, clear the residue from the inner groove of the bar.
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 ?, clean all sawdust from the Guide Bar and sprocket hole. When rail top is uneven, use a flat file to restore square edges and sides.

Diagram showing worn groove versus correct groove for a guide bar.

Replacing Guide Bar

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 repair parts list or on the decal located on the electric chain saw.

Replacing Chain

Replace chain when cutters are too worn to sharpen or when chain stops. Only use replacement chain noted in this manual.

Only handle the saw chain with gloves ? and remove the battery pack ? first!

Inspect the saw chain and the guide bar for damage or signs of wear.

Sharpening Saw Chain

WARNING: Remove the battery pack ? before servicing. Severe injury or death could occur from electrical shock ⚡ or body contact with moving chain. Cutting edges on chain are sharp. Use protective gloves ? when handling chain. Keep chain sharp. Your saw will cut faster and more safely. A dull chain will cause undue sprocket, Guide Bar, chain, and motor wear. If you must force chain into wood and cutting creates only sawdust with few large chips, chain is dull.

Instructions Concerning the Proper Techniques for Limbing and Cross-Cutting

1). 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 1. Branches under tension should be cut from the bottom up to avoid binding the electric chain saw.

Figure 1: Diagram showing limbing a tree.

2). 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 2, it is cut from the top (overbuck), avoid contacting ground as this will greatly reduce the chain sharpness.

Figure 2: Diagram illustrating bucking a log supported along its entire length.

When the log is supported on one end, as illustrated in Figure 3, cut 1/3 the diameter from the underside (underbuck) (1). Then make the finished cut by overbucking (2) to meet the first cut.

Figure 3: Diagram illustrating bucking a log supported on one end.

When the log is supported on both ends, as illustrated in Figure 4, 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.

Figure 4: Diagram illustrating bucking a log supported on both ends.

When bucking on a slope always stand on the uphill side of the log, as illustrated in Figure 5. When "cutting through", to maintain complete control release the cutting pressure near the end of the cut without relaxing your grip on the electric 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 electric chain saw. Always stop the motor before moving from tree to tree.

Figure 5: Diagram illustrating bucking on a slope.
