MAINTENANCE
Position the chain so there is a loop at the back of the
bar.
Hold the chain in position on the bar and place the loop
around the sprocket (E).
Fit the bar fl ush against the mounting surface so that
the bar studs are in the long slot of the bar.
NOTE: When placing the bar on the bar studs (F),
ensure that the adjusting pin (G) is in the chain tension
pin hole (H).
Replace the clutch cover (I) and bar mounting nuts
(J).
Finger-tighten the bar mounting nuts. The bar must be
free to move for tension adjustment.
Remove all slack from the chain by turning the chain
tensioning screw (K) clockwise until the chain seats
snugly against the bar with the drive links in the bar
groove.
Lift the tip of the guide bar up to check for sag.
Release the tip of the guide bar and turn the chain
tensioning screw 1/2 turn clockwise. Repeat this
process until sag does not exist.
Hold the tip of the guide bar up and tighten the bar
mounting nuts securely.
The chain is correctly tensioned when there is no sag on
the underside of the guide bar, the chain is snug, but it can
be turned by hand without binding. Ensure that the chain
brake is not set.
NOTE: If chain is too tight, it will not rotate. Loosen the
bar nuts slightly and turn the tension adjuster 1/4 turn
counterclockwise. Lift the tip of the guide bar up and
retighten the bar nuts securely. Ensure that the chain will
rotate without binding.
ADJUSTING THE CHAIN TENSION (Fig. 44 - 46)
WARNING
Never touch or adjust the chain while the motor is
running. The saw chain is very sharp. Always wear
protective gloves when performing maintenance on
the chain.
Stop the engine before setting the chain tension.
Make sure the bar mounting nuts are loosened to fi nger
tight.
Turn the chain tensioning screw clockwise to tension
the chain.
NOTE: A cold chain is correctly tensioned when there

is no slack on the underside of the guide bar, the chain
is snug, and it can be turned by hand without binding.
Retension the chain whenever the fl ats on the drive
links (A) hang out of the bar groove.
NOTE: During normal saw operation, the temperature
of the chain increases. The drive links of a correctly
tensioned warm chain will hang approximately 1.25
mm. out of the bar groove. The tip of the combination
wrench can be used as a guide to help determine the
correct warm chain tension.
NOTE: New chains tend to stretch; check the chain
tension frequently and tension as required.
CHAIN MAINTENANCE (Fig. 47 - 48)
Use only a low-kickback chain on this saw. This fast-
cutting chain provides kickback reduction when properly
maintained.
For smooth and fast cutting, maintain the chain properly.
The chain requires sharpening when the wood chips are
small and powdery, the chain must be forced through the
wood during cutting, or the chain cuts to one side. During
maintenance of the chain, consider the following:
Improper fi ling angle of the side plate can increase the
risk of severe kickback.
Raker (depth gauge) clearance (A).
• Too low increases the potential for kickback.
• Not low enough decreases cutting ability.
If the cutter teeth hit hard objects such as nails and
stones, or are abraded by mud or sand on the wood,
have an authorized service center sharpen the chain.
NOTE: Inspect the drive sprocket (B) for wear or
damage when replacing the chain. If signs of wear
or damage are present in the areas indicated, have
the drive sprocket replaced by an authorized service
center.
NOTE: If you do not fully understand the correct procedure
for sharpening the chain after reading the instructions that
follow, have the saw chain sharpened by an authorized
service center or replace with a recommended low-kickback
chain.

CAUTION
A chain tensioned while warm may be too tight upon
cooling. Check the "cold tension" before next use.
CAUTION
Check that the switch is in the STOP "
before you work on the saw.
