1. Make a lower level notching cut. Make sure that this
cut is
a) 1/3 wide of the diameter of the tree.
b) Perpendicular to the felling direction.
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 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 which
prevents the tree from twisting and felling to the
wrong direction.
When the felling cut gets near the hinge, the tree falls.
Stop the felling cut if the tree
• Does not fall to the correct direction or
• Move rearward and forward and stuck the chain.
3. Use felling wedge to open the cut and let the tree fall
to 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) Go away through the escape path. Be careful with
overhead branches and your footing.

LIMB A TREE

Figure 11.
Limbing is to remove the branches from a fallen tree.
1. Keep the larger lower branches to hold the log off the
ground.
2. Remove the small limbs in one cut.
3. Limb the branches with tension from the bottom to up.
4. Keep the larger lower branches as a support until the log
is limbed.

BUCK A LOG

Figure 12-15.
Bucking is to cut a log into lengths. Keep your body balance.
If it is possible, lift the log and hold it with branches, logs or
chock.
• When the log is held along the full length, cut it from the
top.
• When the log is held on one end,
1. Cut the first time 1/3 of the diameter from the bottom.
2. Cut the second time from the top to complete the
bucking.
• When the log is held on two ends,
CAUTION
English
1. Cut the first time 1/3 of the diameter from the top.
2. Cut the second time lower 2/3 from the bottom to
complete the bucking.
• When the log is on a slope,
1. Stand on the uphill side.
2. Control the chainsaw.
3. Hold the handles tightly.
4. Release the cut pressure near the end of the cut.
Do not let the chain touch the ground.
When bucking is complete,
1. Release the trigger.
2. Stop the chainsaw fully.
3. Move the chainsaw from tree to tree.

MAINTENANCE

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.
Do not use strong solvents or detergents on the plastic
housing or components.
Remove the battery pack from the machine before
maintenance.

ADJUST THE CHAIN TENSION

Figure 2-7.
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 as tightly as possible, but not so tight that
you cannot pull it round freely by hand.
A slack chain may jump off and cause serious or even fatal
injury.
Wear protective gloves if you touch the chain, bar or areas
around the chain.
1. Stop the machine.
2. Loosen the lock nuts with the wrench.
