ENGINE
A list of key engine maintenance items required for good
performance is listed here. Consult the separate
Engine
Owners Manual
for the manufacturer’s recommendations
for any and all engine maintenance.
1. Check engine oil level before each use and maintain oil
level as instructed in the separate
Engine Owners Manual
.
2. Service air filter per Engine Owners Manual
recommendations. Clean every few hours under
extremely dusty conditions. Poor engine performance
and flooding usually indicates that the air cleaner should
be serviced.
CAUTION
Never run the engine without an air filter installed. Running
the engine without the filter can cause excessive engine
wear and damage.
3. Clean engine regularly with a cloth or brush. Keep the top
of the engine free of debris to permit proper air circulation.
Remove all grass, dirt and combustible material from
muffler area.
BLADE CARE
For best results, mower blade must be kept sharp. Clean
and inspect blade for cracks, nicks or other damage.
Replace a blade that is badly worn, bent or damaged with a
factory replacement blade.
CAUTION
Use only a replacement blade shown in the Repair Parts
section of this manual. Using a blade not approved by the
manufacturer of your mower is hazardous, could damage
your mower and void your warranty.
CAUTION
Use extra care when servicing mower blades. Blades are
sharp. To protect your hands, wrap the blade or wear gloves
when handling.
TO REMOVE BLADE (FIG. 8)
1. Disconnect spark plug wire from spark plug and place
wire where it can not come in contact with plug.
2. Turn mower on its side. Make sure air filter and carburetor

prevent blade from turning when removing blade bolt.

Protect your hands with gloves and/or wrap blade
with heavy cloth.
