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 war-
ranty, the operator must maintain unit as
instructed in this manual. Various adjustments
will need to be made periodically 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.
S ON/STOP Switch - - Ensure ON/STOP switch
functions properly by moving the switch to the
STOP position. Make sure engine stops; then
restart engine and continue.
S Fuel Tank - - Do not use saw if fuel tank shows
signs of damage or leaks.
S Oil Tank - - Do not use saw if oil tank shows
signs of damage or leaks.

FASTENERS AND PARTS
S Bar Nuts
S Chain
S Muffler
S Cylinder Shield
S Air Filter

S Vibration Mounts
S Starter Housing
S Front Hand Guard
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 maintenance:
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 dam-
age the chain and make cutting difficult.
