Adjusting The Chain Lubrication - Makita UC3551A Instruction Manual

Adjusting the chain lubrication

You can adjust the oil pump feed rate with the adjusting
screw.
WORKING WITH THE CHAIN SAW
CAUTION:
• Always use a front handle and rear handle and
firmly hold the tool by both front handle and rear
handle during operations.
• Always secure the timber to be cut, otherwise
the cut fragments may cause personal injury.
Bucking
► 1. Spike bumper
For bucking cuts, rest the spike bumper shown in the
figure on the wood to be cut.
With the saw chain running, saw into the wood, using
the rear handle to raise the saw and the front one to
guide it. Use the spike bumper as a pivot.
Continue the cut by applying slight pressure to the front
handle, easing the saw back slightly. Move the spike
bumper further down the timber and raise the front
handle again.
When making several cuts, switch the chain saw off
between cuts.

CAUTION:
• If the upper edge of the bar is used for cutting,
the chain saw may be deflected in your direction
if the chain becomes trapped. For this reason,
cut with the lower edge, so that the saw will be
deflected away from your body.
Cut wood under tension on the pressure side (A) first.
Then make the final cut on the tension side (B). This
prevents the bar from becoming trapped.
Limbing
CAUTION:
• Limbing may only be performed by trained
persons. A hazard is presented by the risk of
kick-back.
When limbing, support the chain saw on the trunk if
possible. Do not cut with the tip of the bar, as this pres-
ents a risk of kickback.
Pay particular attention to branches under tension. Do
not cut unsupported branches from below.
Do not stand on the felled trunk when limbing.
