Replacing the Guide bar and Saw Chain
wARNiNG
Always use a low-kickback saw chain, which significantly
reduces the danger of kickback. Low-kickback saw chain does
not completely eliminate kickback. A low-kickback or “safety
chain,” should never be regarded as total protection against
injury.
When replacing the guide bar and saw chain, only use the
replacement parts specified by the manufacturer or their
equivalents. Refer to
Replacement Parts
. Use of any unauthorized
parts or accessories could lead to serious injury to the operator or
damage to the chainsaw and will VOID the warranty.
Always use a replacement saw chain designated as
“low-kickback” or a saw chain that meets the low-kickback
performance requirements.
Maintaining the Air filter
wARNiNG
To avoid serious personal injury, always stop the engine and
allow it to cool before cleaning or maintaining the chainsaw.
Failure to maintain the air filter can result in poor performance or
can cause permanent damage to the engine. Engine failure due
to improper air filter maintenance is not covered by the product
warranty.
Cleaning the air Filter
1. Turn the knob on the air filter cover counter-clockwise to
loosen the air filter cover (Fig. 41).
2. Remove the air filter cover (Fig. 41).
3. Remove the air filter (Fig. 42).
4. Wash the air filter in mild detergent and water. Rinse the air
filter thoroughly and allow it to dry.
5. Reinstall the air filter onto the mounting post (Fig. 42). Make
sure the opening in the air filter sits securely in the air intake
(Fig. 42).
6. Place the air filter cover back onto the chainsaw. Insert
the tab on the air filter cover into the slot on the chain saw
housing
(Fig. 41).
7. Turn the knob clockwise to tighten the air filter cover
securely.
