OPERATION
The following section on the operation of the chain
saw is a general guide only. The use of a chain saw
by an inexperienced person can be extremely
dangerous. If you are unsure, please seek the
assistance of a professional or get suitable training
before using the chain saw.
WARNING.
Before every use check the
operation of the chain break and oil
pump.
BUCKING SPIKES
The chainsaw has bucking spikes (Fig.16-A) to as-
sist with cutting and reduce the chance of
kickback. Keep the bucking spikes touching the
wood when cutting will help prevent any pinching or
kick-back.
BUCKING
Bucking is cutting a log into lengths for easier
handling. To saw a log lying on the ground, first
saw halfway, then roll the log over and cut from the
opposite side (Fig.17). To saw the end of a log
supported off the ground, first saw up from the
bottom one-third through the log then finish by
sawing down from the top. To saw a log in the
middle of two supports holding it off the ground,
first saw down from the top one-third through the
log then finish by sawing up from the bottom
(Fig.18).When bucking on a slope, always stand on
the uphill side.
WARNING.
Be careful that the chain
does not cut into the ground when
bucking as this causes rapid dulling of
the chain.
LIMBING
Limbing is the process of removing the branches
from a fallen tree. Check the direction in which a
branch will bend before cutting it. Always cut on the
opposite side to the bending direction so that the
guide bar is not pinched in the cut. For large limbs
that cannot be removed in one cut, make an initial
cut from the bent side and finish by sawing from
the opposite direction (Fig.19). Do not remove
limbs that are supporting the fallen tree on the
ground until the tree has been cut into lengths.
WARNING.
Always keep a well balanced
stance. Do not stand on the log. Be alert
to the fact that the log may roll over.
When working on a slope, always stand
on the uphill side of the log.
