Bucking
Bucking is cutting a fallen log into lengths. Make sure
you have a good footing and stand uphill of the log
when cutting on sloping ground. If possible, the log
should be supported so that the end to be cut off is
not resting on the ground. If the log is supported at
both ends and you must cut in the middle, make a
downward cut halfway through the log and then make
the undercut. This will prevent the log from pinching
the bar and chain. Be careful that the chain does not
cut into the ground when bucking as this causes rapid
dulling of the chain. When bucking on a slope,
always stand on the uphill side.
1. Log supported along entire length: Cut from
top (overbuck), being careful to avoid cutting into
the ground (Fig. 16A).
2. Log supported on 1 end: First, cut from bottom
(underbuck) 1/3 diameter of log to avoid
splintering. Second, cut from above (overbuck) to
meet first cut and avoid pinching (Fig. 16B).
3. Log supported on both ends: First, overbuck
1/3 diameter of log to avoid splintering. Second,
underbuck to meet first cut and avoid pinching
(Fig. 16C).
Note: The best way to hold a log while bucking is to
use a sawhorse. When this is not possible, the log
should be raised and supported by the limb stumps or
by using supporting logs. Be sure the log being cut is
securely supported.
Bucking using a sawhorse (Fig. 17)
For personal safety and ease of cutting, the correct
position for vertical bucking is essential (Fig. 17).
A. Hold the saw firmly with both hands and keep the
saw to the right of your body while cutting.
B. Keep the left arm as straight as possible.
C. Keep weight on both feet.
Caution: When working with the saw, always
make sure that the saw chain and chain bar are
sufficiently lubricated.

9. Maintenance

Warning: All maintenance work on the chainsaw
apart from the work described in this manual may
only be carried out by authorized after-sales service
personnel.
9.1 Chain brake operational test
Test the chain brake periodically to ensure proper
function.
Perform a chain brake test prior to initial cutting,
following extensive cutting, and definitely following
any Chain brake service.
Test chain brake as follows (Fig. 10) :
1. Place saw on a clear, firm, flat surface.
2. Start engine.
3. Grasp the rear handle (A) with your right hand.
4. With your left hand, hold the front handle (B) [not
chain brake lever (C)] firmly.
