Engine Care
A list of key engine maintenance jobs required for good
performance by the pressure washer 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 as instructed in engine manual. 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,
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
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.
