Cleaning the air filter
1. Loosen the filter cover knob
and remove the filter cover.
3. Split the air filter into its two halves and clean
the mesh. Dry particles can be removed by
tapping on a hard surface. More stubborn dirt
may require using an air compressor.
4. Re-assemble the two halves and replace
the air filter, filter cover and filter cover knob.
Maintaining the guide bar
Most guide bar problems can be prevented by keeping the chainsaw well
maintained. Insufficient guide bar lubrication and operating the saw with a
chain that is TOO TIGHT will contribute to rapid bar wear.
To help minimize bar wear, the following guide bar maintenance
procedures are recommended.
• The bar should be reversed every 8 working hours to ensure uniform
wear. Keep the bar groove and lubrication
hole clean.
• Check the bar rails frequently for wear and,
if necessary, remove the burs and square-up
the rails using the flat file.
• Oil passages on the bar should be cleaned
to ensure proper lubrication of the bar and
chain during operation. Grease the nose sprocket at the tip of the
guide bar.
Note:
The condition of the oil passages can be easily checked. If the
passages are clear, the chain will automatically give off a spray of
oil within seconds of starting the saw. Your saw is equipped with an
automatic oiler system.
Chain tension
Check the chain tension frequently and adjust as often as necessary to
keep the chain snug on the bar, but loose enough to be pulled around by
hand. (see
Adjusting the chain tension
)

8. CUTTING METHODS
Bucking is cutting a log into lengths for easier
handling. To saw a log lying on the ground,
first saw halfway, then roll the log over and
cut from the opposite side.
To saw the end of a log supported off the
ground, first saw up from the bottom one-third
through the log then finish by sawing down
from the top. To saw a log in the middle of two
supports holding it off the ground, first saw down from the top one-third
through the log then finish by sawing up from the bottom.
Limbing is the process of removing the
branches from a fallen tree. Check the
direction in which a branch will bend
before cutting it. Always cut on the
opposite side to the bending direction
so that the guide bar is not pinched in
the cut. For large limbs that cannot be
removed in one cut, make an initial cut from the bent side and finish
by sawing from the opposite direction. Do not remove limbs that are
supporting the fallen tree on the ground until the tree has been cut into
lengths.
Pruning is the removal of a limb or branch
from a standing tree.
Felling a tree
Decide the direction in which you wish
the tree to fall, taking into account the
direction of the wind, the position of
branches, lean of the tree, ease of
subsequent limbing and bucking and
other factors prevalent at the time.

WARNING!:
FELLING A TREE SHOULD ONLY BE
DONE BY TRAINED OPERATORS.
WARNING!:
ALWAYS KEEP A BALANCED STANCE.
DO NOT STAND ON THE LOG. BE ALERT TO THE
FACT THAT THE LOG MAY ROLL OVER. WHEN WORKING
ON A SLOPE, ALWAYS STAND ON THE UP HILL SIDE OF
THE LOG.
WARNING!:
BEFORE CLEANING YOUR CHAINSAW
OR CARRYING OUT ANY MAINTENANCE
PROCEDURE, MAKE SURE THAT THE ENGINE IS OFF
AND IS COOL. DISCONNECT THE SPARK PLUG TO
PREVENT ACCIDENTAL STARTING
CAUTION!:
AVOID CUTTING INTO THE GROUND AS THIS
WILL VERY QUICKLY DULL THE SAW CHAIN.
WARNING!:
DO NOT USE AN UNSTABLE FOOTHOLD
OR LADDER. DO NOT OVERREACH. DO NOT SAW
ABOVE SHOULDER HEIGHT. ALWAYS USE BOTH HANDS
TO HOLD THE SAW. FIRST CUT UP FROM THE BOTTOM
AND FINISH DOWN FROM THE TOP.
WARNING!:
WEAR HEAVY GLOVES WHEN
HANDLING THE CHAIN. HOLD THE GUIDE BAR
SECURELY IN A VICE.
