Maintenance
IMPORTANT: Only a special air cleaning gun should be used. Concentrated air pressure
from an ordinary nozzle may severely damage filter element. DO NOT exceed 30 PSI (2.1
bar) when cleaning filter element.
4. Inspect filter to determine if it is practical to clean or for damage after cleaning
filter. If necessary, repeat step three to remove additional dirt.
a. Hold a bright light inside element--check carefully for holes. Discard any
element that shows the smallest hole or rupture.
b. Be sure outer screen is not dented. Vibration would quickly wear a hole in
filter.
c. Be sure filter gasket is in good condition. If gasket is damaged or missing,
replace element.
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 interval. Clean engine before removing spark plug to
prevent contaminants from entering engine. 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 18-22 ft lb (24.4-29.8 Nm).
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 required.
 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 interval. 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.
