GENERAL RECOMMENDATIONS
The warranty on this unit does not cover
items that have been subjected to operator
abuse or negligence. To receive full value
from the warranty, the operator must main-
tain unit as instructed in this manual. Various
adjustments will need to be made periodical-
ly to properly maintain your unit.
S
Once a year, replace the spark plug, air filter,
and check guide bar and chain for wear. A
new spark plug and air filter assures proper
air-fuel mixture and helps your engine run
better and last longer.
CHECK FOR DAMAGED OR
WORN PARTS
Contact an authorized service dealer for re-
placement of damaged or worn parts.
NOTE:
It is normal for a small amount of oil
to appear under the saw after engine stops.
Do not confuse this with a leaking oil tank.

switch functions properly by moving the
switch to the STOP position. Make sure en-
gine stops; then restart engine and continue.

CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A dull
chain makes a sawdust powder and cuts
slowly. See CHAIN SHARPENING.
CHECK GUIDE BAR
Conditions which require guide bar mainte-
nance:
S
Saw cuts to one side or at an angle.
S
Saw has to be forced through the cut.
S
Inadequate supply of oil to bar/chain.
Check the condition of guide bar each time
chain is sharpened. A worn guide bar will
damage the chain and make cutting difficult.
After each use, ensure ON/STOP switch is
in the STOP position, then clean all sawdust
from the guide bar and sprocket hole.
To maintain guide bar:
S
Move ON/STOP switch to STOP.
S
Loosen and remove bar nuts and clutch
cover. Remove bar and chain from saw.
S
Clean the oil holes and bar groove after
each 5 hours of operation.
Remove Sawdust From
Guide Bar Groove
Oil Holes
S
Burring of guide bar rails is a normal
process of rail wear. Remove these burrs
with a flat file.
S
When rail top is uneven, use a flat file to re-
store square edges and sides.
Correct Groove
Worn Groove
File Rail Edges
and Sides
Square
Replace guide bar when the groove is worn,
the guide bar is bent or cracked, or when ex-
cess heating or burring of the rails occurs. If re-
placement is necessary, use only the guide bar
