CHECK
FOR DAMAGED OR
WORN PARTS
Contact Sears Service Center for re-
placement of damaged or worn parts.
NOTE: It is normal for a small amount
of oil to appear under the saw after en-
gine stops. Do not confuse this with a
leaking oil tank.
• 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.
• Fuel Tank - Do not use saw if fuel
tank shows signs of damage or
leaks.
• Oil Tank - Do not use saw if oil tank
shows signs of damage or leaks.

CHECK CHAIN TENSION
_I_WARNING: Wear protective
gloves when handling chain. The
chain is sharp and can cut you even
when it is not moving.
Chain tension is very important.
Chains stretch during use.
This is especially true during the first
fewtimes you use your saw. Always
check chain tension each time you use
and refuel your saw.
1. Use the screwdriver end of the
chain adjustment tool (bar tool) to
move chain around guide bar to
ensure kinks do not exist. The
chain should rotate freely.

4. Using bar tool, roll chain around
guide bar to ensure all links are in
bar groove.
5. Lift up tip of guide bar to check for
sag. Release tip of guide bar, then
turn adjusting screw until sag does
not exist.
6. While lifting tip of guide bar, tighten
chain brake nuts securely with the
bar tool.

7. Use the screwdriver end of the bar
tool to move chain around guide
bar.
8. If chain does not rotate, it is too
tight. Slightly loosen chain brake
nuts and loosen chain by turning
the adjusting screw counterclock-
wise. Retighten chain brake nuts.
9. If chain is too loose, it will sag be-
low the guide bar. DO NOT operate
the saw if the chain is loose.
_I_WARNING: If the saw is operated
with a loose chain, the chain could
jump off the guide bar and result in se-
rious injury.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARP-
ENING in the SERVICE AND ADJUST-
MENTS section.
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the
cut.
• 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.
