Saw Chain and Guide 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 totop.
Cleaning

clean, dry air at least once a week. To minimize the risk of eye
injury, always wear ANSI Z87.1 approved eye protection when
perform
ing thisprocedure.

removing/installing attachments or accessories. An
accidental start‑up can causeinjury.
Your
DeWALT power tool has been designed to operate
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper
tool care and regularcleaning.
1. Always start a cut with the saw chain running at
fullspeed.
2. Place the bottom spike
22
of the chainsaw behind the
area of the initial cut as shownbelow.
3. Turn the chainsaw on then rotate the saw chain and bar
down into the tree, using the spike as ahinge.
4. Once the chainsaw gets to a 45° angle, level the
chainsaw again and repeat steps until you cut fullythrough.
5. 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 sawquickly.
CUT FROM TOP (OVERBUCK)
AVOID CUTTING EARTH

• 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 firstcut as shownbelow.

• 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 tocut.
