cut and drop the tree along the desired line
of fall. When the tree begins to fall, remove
the top handle saw from the cut, stop the
motor, put the top handle saw down, and
then use the retreat path as planned. Be
alert of overhead limbs falling and watch
your footing.
LIMBING A TREE See figure 11
Limbing is removing the branches from a
fallen tree. When limbing, leave the larg-
er 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 up, to avoid binding the top
handle saw.
BUCKING A LOG See figure 12 - 15
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 direction for easy cutting:
When the log is supported along the
„
entire length, it is cut from the top
(over buck).
When the log is supported on one
„
end, cut 1/3 of the diameter from the
underside (under buck). Then make
the finished cut by over bucking to
meet the first cut.
When the log is supported on both
„
ends, cut 1/3 of that diameter from
the top (over buck). Then make the
finished cut by under bucking the
lower 2/3 to meet the first cut.
When bucking on a slope, always
„
stand on the uphill side of the log.
When cutting through, to maintain
complete control, release the cutting
pressure near the end of the cut
without relaxing your grip on the top
handle saw handles.
Do not let the chain contact the ground.
After completing the cut, wait for the saw
chain to stop before you move the top han-
dle saw. Always stop the motor before mov-
English (original instructions)
ing from tree to tree.

MAINTENANCE

Always remove the battery pack from the
machine before checking the chain ten-
sion or making adjustments to the chain.
Wear protective gloves while touching
the chain, bar or areas around the chain.
ADJUSTING THE CHAIN TENSION
See figure 2 and figure 7
Loosen the chain cover lock nuts with
„
the supplied wrench. The chain cover
lock nuts do not have to be completely
removed in order to adjust the chain
tension.
Rotate the chain adjustment screw
„
clockwise to increase the chain
tension and rotate counterclockwise to
decrease the chain tension.
Once the chain is at the desired
„
tension, tighten the chain cover lock
nuts.

REPLACING THE BAR AND CHAIN

See Figure 3-7
Remove the battery from the top
„
handle saw.
Remove the chain cover lock nut
„
from chain cover by rotating them
counterclockwise with the wrench.
Remove the chain cover from the
„
mounting surface.
The bar and chain can now be removed
„
by lifting it away from the main body of
the saw and releasing the chain from
the sprocket.
Remove the old chain from the bar.
„
Lay out the new saw chain in a loop
„
and straighten any kinks. The cutters
should face in the direction of chain
rotation. If they face backwards, turn
the loop over.
