Always start a cut with
the chain running at full
speed.
• Place the bottom spike
(R) of the chain saw
behind the area of the
initial cut as shown in
figure 20
.
• 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.
•
Figure 21- When
supported at one end
First, cut 1/3 the
diameter from the
underside (underbuck).
Then make the finishing
cut by overbucking to
meet the first cut.
•
Figure 22-
When
supported at both
ends
First, cut 1/3
down from the
top overbuck.
Then make the
finished cut by
u n d e r b u c k i n g
the lower 2/3 to
meet the first cut.
•
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.

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 DeWALT authorized service center, always using identical
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
CAUTION:
Sharp chain. Always wear protective
gloves when handling the chain.
The chain is sharp and can cut
you when it is not running.
WARNING:
Sharp moving chain. To prevent
accidental operation, ensure that battery is removed from the
tool before performing the following operations.
Failure to do
this could result in serious personal injury.
note:
The cutters will dull immediately if they touch the ground or
a nail while cutting.
