FASTENERS AND PARTS
• Chain Brake Nuts
• Chain
• Muffler
• Cylinder Shield
• Air Filter
• Handle Screws
• Vibration Mounts
• Starter Housing
• Front Hand Guard
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 es-
pecially true during the first few times
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.

2. Loosen chain brake nuts until they
are finger tight against the chain
brake.
3. Turn adjusting screw clockwise un-
til chain solidly contacts bottom of
guide bar rail.
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.
Chain Brake
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 offthe 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.
After each use, ensure ON/STOP
switch is in the STOP position, then
clean all sawdust from the guide bar
and sprocket hole.
