GENERAL CUTTING cont.
BUCKING A LOG cont.
When the log is supported on both
ends, as illustrated, cut 1/3 the
diameter from the top overbuck.
Then make the finished cut by
underbucking the lower 2/3 to meet
the first cut. (See Fig. 21)
When bucking on a slope always
stand on the uphill side of the log,
as illustrated.
When "cutting through", to maintain
complete control release the cutting
pressure near the end of the cut
without relaxing your grip on
the chain saw handles.
Don't let the chain contact
the ground.
After completing the cut, wait for
the saw chain to stop before you
move the chain saw.
Always stop the motor before
moving from tree to tree.
(See Fig. 22)

To maximize bar life, the following bar maintenance is recommended. The bar rails that carry the
chain should be cleaned before storing the tool or if the bar or chain appear to be dirty.
The rails should be cleaned every time the chain is removed. Turn the bar over, top rail becoming
bottom and bottom rail becoming top, around every 5 hours of use.

(see section ASSEMBLY)
2. Using a wire brush, screwdriver or similar tool, clear the
residue from the inner groove of the bar. (See Fig. 22)
3. Make sure to clean oil passages thoroughly.

• Inadequate supply of oil to the bar and chain.
Check the condition of the Guide Bar each time the chain is sharpened. A worn Guide Bar will
damage the chain and make cutting difficult. After each use, with unit disconnected from power
source, clean all sawdust from the Guide Bar and sprocket hole.
