Limbing
Removing the branches from a fallen tree. When limbing, leave
larger lower limbs to support the log off the ground. Remove
the small limbs in one cut. Branches under tension should be
cut from the bottom of the branch towards the top to avoid
binding the chain saw as shown in Figure P. Trim limbs from
opposite side keeping tree stem between you and saw. Never
make cuts with saw between your legs or straddle the limb to
be cut.

WARNING: Recommend that first time users should
practice cutting on a saw horse.
Cutting a felled tree or log into lengths. How you should
cut depends on how the log is supported. Use a saw horse
(Figure Q) whenever possible.
•
Always start a cut with the chain running at full speed.
•
Place the bottom spike

of the initial cut as shown in Figure W.
•
Turn the chain saw on then rotate the chain and bar down
into the tree, using the spike as a hinge.
•
Once the chain saw gets to a 45 degree angle, level the
chain saw again and repeat steps until you cut fully through.
•
When the tree is supported along its entire length, make a
cut from the top (overbuck), but avoid cutting the earth as
this will dull your saw quickly.

When on a slope always stand on the uphill side of the
log. When "cutting through", to maintain complete control
reduce 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 cut to cut.
CARE AND MAINTENANCE
Use only mild soap and damp cloth to clean the tool. Do not
use solvents to clean the plastic housing of the saw. Never let
any liquid get inside the tool; never immerse any part of the tool
into a liquid.
IMPORTanT: To assure product SAFETY and RELIABILITY,
repairs, maintenance and adjustment should be performed
by a D
WALT authorized service center, always using identical
e
replacement parts.
Regular maintenance ensures a long effective life for your
chain saw.
Chain and Bar
After every few hours of use, remove the sprocket cover, guide
bar and chain and clean thoroughly using a soft bristle brush.
Ensure oiling hole on bar is clear of debris. When replacing dull
chains with sharp chains it is good practice to flip the chain bar
from bottom to top.
Saw Chain Sharpening (Fig. R–T)
CAUTION: Sharp chain. Always wear protective gloves
when handling the chain. The chain is sharp and can cut
you when it is not running.
