Engine
A list of key engine maintenance jobs required for good
performance by the mower is given below. Follow the
accompanying engine manual for a detailed list and instructions.
•
Maintain oil level as instructed in engine manual.
•
Service air cleaner and carbon canister filter every 25 hours
under normal conditions. Clean every few hours under
extremely dusty conditions. Poor engine performance
and flooding usually indicates that the air cleaner should
be serviced. To service the air cleaner and carbon canister
filter, refer to the engine manual.
•
Clean spark plug and reset the gap once a season. Spark
plug replacement is recommended at the start of each
mowing season. Check engine manual for correct plug
type and gap specifications.
•
Clean engine regularly with a cloth or brush. Keep the
top of the engine clean to permit proper air circulation.
Remove all grass, dirt, and combustible debris from muffler
area.
•
Engines stored between 30 and 90 days need to be treated
with a gasoline stabilizer to prevent deterioration and gum
from forming in fuel system or on essential carburetor
parts.
