3. Log supported on both endsiFirsi,
overbuck 1/3 diameter of log to
avoid splintering.Second, underbuck
to meet first cut and avoid pinching
(Figure 5-30).
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 iogs.Be sure the log
being cut is securely supported.
5-4.BUCKING USING A
SAWHORSE
For personal safety and ease of cutting,
the correct position for vertical bucking
is essential (Figure 5-4A).
VERTICAL CUTTING:
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
While the saw is cutting, be sure the
chain and bar are being properly
lubricated.

6 - BAR/CHAIN MAINTENANCE
6-1.GUIDE BAR MAINTENANCE
WARNING
Ensure that the power cord is disconn­
ected before performing any maintena­
nce on your saw.
Proper maintenance of the guide
bar,as explained in this section,Is
essential to keep your saw in good
working order.
GUIDE BAR MAINTENANCE :
Most guide bar problems can be
prevented merely by keeping the chain
saw well maintained
Incorrect filing and non-uniform cutter
and depth gauge settings cause most
guide bar problems, primarily resulting
in uneven bar wear.As the bar wears
unevenly, the rails widen, which may
cause chain clatter and difficulty in
making straight cuts.
Insufficient guide bar lubrication and
operating the saw with a chain that is
TOO TIGHT will contribute to rapid bar
wear (see Section 6-2).
To help minimize bar wear, the
following guide bar maintenance is
recommended.
BAR WEAR- Turn guide bar frequently
at regular intervals (for example, after 5
hours of use), to ensure even wear on
top and bottom of bar.
BAR GROOVES - Bar grooves (or rails
which support and carry the chain)
should be cleaned if the saw has been
heavily used or if the saw chain
appears dirty.Rails should always be
cleaned every time the saw chain is
removed,
OIL PASSAGES- Oil passages at bar
pad should be cleaned to ensure proper
lubrication of the bar and chain during
operation.This can be done using a soft
wire small enough to insert into the oil
discharge hole,
TO CLEAN GUIDE BAR RAILS:
1. Remove sprocket cover, bar and
chain (see Section 3-4).
Using a screwdriver, putty knife, wire
brush or other similar instrument,
dear residue from the rails on the
guide bar.
This will keep the oil passages open
to provide proper lubrication to the
bar and chain (Figure 6-1 A).
Reinstall the bar, chain and bar bolt
retaining nuts, (See Section 3-4).
