4. Once the chain saw gets to a 45 degree angle, level
the chain saw again and repeat steps until you cut
fullythrough.
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 sawquickly.

First, cut 1/3 the diameter from the underside
(underbuck). Then make the finishing cut by
overbucking 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.
MAINTENANCE

WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start-up can causeinjury.
Regular maintenance ensures a long effective life for your
chainsaw.
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 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.
To get the best possible performance from your chain saw
it is important to keep the teeth of the saw chain sharp.
Follow these helpful tips for proper saw chain sharpening:
1. For best results use a 4.5mm file and a file holder or
filing guide to sharpen your saw chain. This will ensure
you always get the correct sharpeningangles.
2. Place the file holder flat on the top plate and depth
gauge of thecutter.
3. FigureT- Keep the correct top plate
21
filing angle line
of 30° on your file guide parallel with your chain (file at
60° from chain viewed from the side).
4. Sharpen cutters on one side of the chain first. File from
the inside of each cutter to the outside. Then turn your
saw around and repeat the processes (2, 3, 4) for cutters
on the other side of thechain.
NOTE: Use a flat file to file the tops of the rakers (portion
of chain link in front of the cutter) so they are about
.025" (.635 mm) below the tips of the cutters as shown
in FigureU.
5. FigureV- Keep all cutter lengthsequal.
6. If damage is present on the chrome surface of the
top plates or side plates, file back until such damage
isremoved.

CAUTION: After filing, the cutter will be sharp, use
extra caution during thisprocess.
NOTE: Each time the chain is sharpened, it loses some of
the low kickback qualities and extra caution should be used.
It is recommended that a saw chain be sharpened no more
than fourtimes.
