Maintenance
Air Filter
Wash the parts with water and dry thoroughly. Remove the pre-cleaner cap to access the
foam pre-cleaner and paper element.
Clean foam pre-cleaner in warm soapy water, rinse and dry thoroughly. Apply oil to the
foam and squeeze out excess oil. The engine will smoke if too much oil is left in the
foam.
Clean the paper element by tapping the element lightly on a hard surface to remove
excess dirt or blow pressurized air (30psi max) through the filter from the air cleaner
cover side. Do not brush the dirt off.
Reassemble the cleaned air cleaner components. Replace elements if damaged or exces-
sively dirty.
Spark Plug
The recommended spark plug is a BPR6ES (NGK) or W20EPR-U (DENSO). To ensure proper
engine operation, the spark plug must be properly gapped and free of deposits. Clean and
replace at scheduled maintenance. Clean engine before removing spark plug. Visually
inspect the spark plug and discard if insulator or tip is damaged. Check that the spark
plug washer is in good condition. If spark plug is to be reused, clean with a wire brush
and set gap .028-.031in(.70-.80mm). Thread the spark plug in by hand to prevent cross
threading. After the spark plug is seated, tighten with a spark plug wrench to compress
the washer.
 If installing a new spark plug, tighten ½ turn after the spark plug seats to
compress the washer.
 If reinstalling a used spark plug, tighten 1/8 to ¼ turn after the spark plug seats
to compress the washer.
Note:
 The spark plug must be securely tightened. An improperly tightened spark plug
can become very hot and may cause engine damage.
 Use only the recommended spark plug or equivalent. A spark plug that has an
improper heat range may cause engine damage.
Engine RPM
 Start the engine and allow it to warm up to normal operating temperature,
check the idle speed 1400 +/- 100, and adjust the idle stop screw as re-
quired.
· Check the full speed 3600 +/-100 and adjust the full speed stop screw as
required.
Cooling System
The machine should be cleaned at scheduled maintenance. This should include cleaning
the air inlet screens and the engine cooling fins. Wash machine with warm soapy water,
rinse off mud and dirt with water, and use pressurized air(30psi max) to blow dirt and
debris from engine.
Valve Clearance
Due to special tool requirements and training, an authorized engine dealer should
perform this service unless the owner has the proper tools and proper shop manuals.
