Section 3 - MAINTENANCE
WARNING
DO NOT attempt any maintenance, adjustments or
service with engine and blade running. STOP engine
and blade. Remove key. Disconnect spark plug wire
and secure away from spark plug. Engine and
components are HOT. Avoid serious burns, allow
sufficient time for all components to cool. Wear
heavy leather gloves when handling or working
around cutting blades. Blades are extremely sharp
and can cause severe injury.
3.2.4. CHECK MOWER BLADE
1.
Disconnect spark plug wire and secure end away
from plug.
2.
Tilt mower up on its rear wheels for access to
the blade cap screw. See Figure 3.2.
IMPORTANT: DO NOT
tip machine with carburetor or
spark plug down. Oil from crankcase will saturate the air
filter and cause the engine to be hard to start or not start
at all. If contamination does occur, the air filter will have to
be replaced.
3.
Check torque of blade retaining cap screw.
Recommended torque should be 30 to 40 ft. lbs.
See Figure 3.2.
4.
Check blade for sharpness, wear and damage.
Refer to Section “BLADE WEAR LIMITS”.
3.2.5. CHECK ENGINE to TRANSMISSION
DRIVE BELT

Visually check belt for cracking, fraying, severed
or belt strands exposed. Replace belt before operating
