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.
Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting
into the ground (Fig. 14a).
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.
14b).
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. 14c)
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
For personal safety and ease of cutting, the correct position for vertical bucking is essential (fig.
15).
Vertical cutting:
Hold the saw firmly with both hands and keep the saw to the right of your body while
cutting.
Keep the left arm as straight as possible.
Keep weight on both feet.
Caution: while the saw is cutting, be sure the chain and bar are being
properly lubricated.
10 MAINTENANCE INSTRUCTIONS
All chain saw service, other than items listed here in your user manual maintenance
instructions, should be performed by a professional.
10.1
Preventive maintenance
A good preventive maintenance program of regular inspection and care will increase life and
improve performance of your chain saw. This maintenance checklist is a guide for such a
program. Cleaning, adjustment, and parts replacement may be required, under certain
conditions, at more frequent intervals than those indicated.
