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
by removing the engine cover (see sketch).

MUFFLER AND EXHAUST PORTS
The muffler should be removed and serviced after each fifty (50) hours of use. At the same time,
the exhaust ports should be cleaned and inspected. An AUTHORIZED MARUYAMA DEALER
should be contacted for this service.
GENERAL CLEANING AND TIGHTENING
The MARUYAMA power blower will provide maximum performance for many hours, if it is main-
tained properly. Good maintenance includes regular checking of all fasteners for correct
tightness, and cleaning the entire machine. Contact an authorized MARUYAMA dealer for
additional maintenance suggestions.
SPARK ARRESTER
1. Remove the screw from the muffler.
2. Take the spark arrester out off the muffler, and then clean by brushing it.
3. Return the spark arrester to the muffler.
4. Tighten the screw securely.
For long-term storage of the power blower, first perform all regular maintenance procedures and
needed repairs. Empty the fuel tank. Disconnect the fuel supply line from the carburetor and
depress the primer bulb until fuel stops discharging from the fuel-return line.
Start the engine and allow it to run until it stops. Pull the starter cord a few times to remove any
excess fuel from the engine. Remove the spark plug and insert a small amount of oil into the
cylinder. Slowly pull the starter cord and bring the piston to a position closest to the spark plug
hole. Re-install the spark plug. Apply a thin coating of oil to all the metal surfaces and store the
power blower in a dry place.
