AIR FILTER
The air filter should be inspected each time the duster is used (or more often with
extreme conditions). To inspect, remove the air filter cover and remove the filter from
the case. Clean air filter(s) by gently tapping element or cleaning with a suitable
solvent the filter should be completely dry before using again.
SPARK PLUG
The spark plug should be removed from the engine and checked after each fifty (50)
hours of use. The tips can be cleaned with a stiff brush. Adjust the gap to .024” -
.028” (0.6 - 0.7mm) inches (see sketch). Replace the spark plug if it is oil-fouled or
damaged.
CAUTION
The correct torque for the spark plug is 95 - 148 in. lbs. (10.7 - 16.6 N ・ m) Do not
over-tighten.
COOLING FINS
Free passage of air flow through the cylinder cooling fins is required to prevent poor
engine performance and shortened engine life. Regularly check and clean all debris from
the cooling fins. An AUTHORIZED MARUYAMA DEALER should be contacted for this
service.
MUFFLER AND EXHAUST PORTS
The muffler should be removed and serviced after each one fifty (50) hours of use. At
the same time, the exhaust ports should be cleaned and inspected. An
