WARNING
DO NOT attempt any maintenance, adjustments or
service with engine and blade running. STOP engine
and blade. 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.
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.
3.2.3. 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. Do not tilt mower with spark
plug or carburetor down. See Figure 3.4.
3. Check torque of blade retaining cap screw.
Recommended torque should be 40 ft. lbs. See
Figure 3.4.
4. Check blade for sharpness, wear and damage.
Refer to Section “Blade Wear Limits”.
3.2.4. CHECK ENGINE DRIVE BELT
1. Visually check engine drive belt for cracking,
fraying, severed or belt strands exposed. If worn or
damaged, replace belt before operating mower.
3.2.5. CHECK TRANSMISSION POLY-V BELT
1. Visually check poly-v belt for cracking, fraying,

from spark plug before any other preparations are
made!

exhaust or air intakes during washing.

underside of the deck. Do not tilt mower with spark plug or
carburetor down. Scrape away any accumulation of grass
with a putty knife and or wire brush.
5. Lubricate all exposed metal with a light coating of oil to
prevent corrosion.
