2. To engage the chain brake, push the chain brake/front hand guard 3 forward until it clicks into place.
3. Pull the chain brake/front hand guard 3 towards the front handle 13 into the “set” position as shown in Figure K.
4. The tool is now ready to use.

NOTE: In the event of kickback, your left hand will come in contact with the front guard, pushing it forward, toward the workpiece. This will stop the tool.

Testing the Chain Brake

Test the chain brake before every use to make sure it operates correctly.

1. Place the tool on a flat, firm surface. Make sure the saw chain 5 is clear of the ground.

2. Grip the tool firmly with both hands and turn the chain saw on.

3. Rotate your left hand forward around the front handle 13 so the back of your hand comes in contact with the chain brake/front hand guard 3 and push it forward, toward the workpiece. The saw chain should stop immediately.

NOTE: If saw does not stop immediately, stop use of tool and bring it to an authorized service center nearest you.

WARNING: Make sure to set chain brake before cutting.

ON/OFF Switch (Fig.L)

Always be sure of your footing and grip the chain saw firmly with both hands with the thumb and fingers encircling both handles.

To turn the unit on, ensure chain brake is not engaged. Push the lock off lever 2 and squeeze the On/Off trigger switch 1 . Once the unit is running, you may release the lock off lever.

In order to keep the unit running you must continue to squeeze the trigger. To turn the unit off, release the trigger.

NOTE: If too much force is applied while making a cut the saw will turn off. To restart saw, you must release the On/Off trigger switch 1 before the saw will restart. Begin your cut again this time with less force. Allow the saw to cut at its own pace.

WARNING: Never attempt to lock a switch in the ON position.

Bubble Level (Fig. A, Q)

WARNING: Do not operate above shoulder height Align bubble levels prior to making a cut.

Ideal for horizontal cutting to ensure a straight, flat cut for fencing, decking or railing posts.

1. Align both bubble levels 7 .

2. Always start a cut with the saw chain running at full speed.

3. Place the bottom spike 20 of the chain saw behind the area of the initial cut.

4. Once a cut has begun and a notch is established in the material, do not change the angle of the cut.

NOTE: Changing the angle will cause the bar to bend.

Common Cutting Techniques (Fig. A, M–S) Felling

The process of cutting down a tree. Be sure battery is fully charged before felling a tree so you can finish on a single charge. Do not fell trees in high wind conditions.

WARNING: Felling can result in injury. It should only be performed by a trained person.

• A retreat path should be planned and cleared as necessary before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall (Figure M).

• 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. Have wedges (wood, plastic or aluminum) and a heavy mallet handy. Remove dirt, stones, loose bark, nails, staples, and wire from the tree where the felling cuts are to be made.

• Notching Undercut - Make the notch 1/3 of the diameter of the tree, perpendicular to the direction of the fall. Make the lower horizontal notching cut first. This will help to avoid pinching of either the saw chain or the guide bar when the second notch cut is being made (Figure N).

• Felling Back Cut - Make the felling back cut at least 2" (51 mm) higher than the horizontal notching cut. 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 ((Figure N).

• As the felling cut gets close to the hinge the tree should begin to fall. If there is any chance that the tree may not fall in the desired direction or it may rock back and bind the saw chain, stop cutting before the felling cut is complete and use wedges to open the cut and drop the tree along the desired line of fall. 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. Be alert for overhead limbs falling and watch your footing.

Limbing

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. Branches under tension should be cut from the bottom of the branch towards the top to avoid binding the chain saw as shown in Figure O. Trim limbs from opposite side keeping tree stem between you and saw. Never make cuts with saw between your legs or straddle the limb to be cut.

Bucking

WARNING: Recommend that first time users should practice cutting on a saw horse.

Cutting a felled tree or log into lengths. How you should cut depends on how the log is supported. Use a saw horse (Figure P) whenever possible.

1. Always start a cut with the saw chain running at full speed.

2. Place the bottom spike 20 of the chain saw behind the area of the initial cut as shown in Figure Q.

3. Turn the chain saw on then rotate the saw chain and bar down into the tree, using the spike as a hinge.

4. Once the chain saw gets to a 45° angle, level the chain saw again and repeat steps until you cut fully through.

5. When the tree is supported along its entire length, make a cut from the top (overbuck), but avoid cutting the earth as this will dull your saw quickly.

• Figure R- When supported at one end first, cut 1/3 the diameter from the underside (underbuck). Then make the finishing cut by overbucking to meet the first cut.

• Figure S- When supported at both ends. First, cut 1/3 down from the top overbuck. Then make the finished cut by underbucking the lower 2/3 to meet the first cut.

• • When on a slope always stand on the uphill side of the log. When “cutting through”, to maintain complete control reduce 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 cut to cut.

Saw Chain Sharpening

CAUTION: Sharp chain. Always wear protective gloves when handling the chain. The chain is sharp and can cut you when it is not running.

WARNING: Sharp moving chain. To prevent accidental operation, ensure that battery is removed from the tool before performing the following operations. Failure to do this could result in serious personal injury.

NOTE: The cutters will dull immediately if they touch the ground or a nail while cutting.

To get the best possible performance from your chain saw it is important to keep the teeth of the saw chain sharp. Follow these helpful tips for proper saw chain sharpening:

1. For best results use a 4.5 mm file and a file holder or filing guide to sharpen your saw chain. This will ensure you always get the correct sharpening angles.

2. Place the file holder flat on the top plate and depth gauge of the cutter.

3. Figure T- Keep the correct top plate 21 filing angle line of 30° on your file guide parallel with your chain (file at 60° from chain viewed from the side).

4. Sharpen cutters on one side of the chain first. File from the inside of each cutter to the outside. Then turn your saw around and repeat the processes (2, 3, 4) for cutters on the other side of the chain.

NOTE: Use a flat file to file the tops of the rakers (portion of chain link in front of the cutter) so they are about .025" (.635 mm) below the tips of the cutters as shown in Figure U.

5. Figure V- Keep all cutter lengths equal. 6. If damage is present on the chrome surface of the top plates or side plates, file back until such damage is removed.

CAUTION: After filing, the cutter will be sharp, use extra caution during this process.

NOTE: Each time the chain is sharpened, it loses some of the low kickback qualities and extra caution should be used. It is recommended that a saw chain be sharpened no more than four times.

Cleaning

WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing this procedure.

WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the plastic materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

Saw Chain and Guide Bar

After every few hours of use, remove the sprocket cover, guide bar and chain and clean thoroughly using a soft bristle brush. Ensure oiling hole on bar is clear of debris. When replacing dull chains with sharp chains it is good practice to flip the chain bar from bottom to top.
