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 0.8 - 0.9 mm (see
sketch). Replace the spark plug if it is oil-fouled or damaged .
CAUTION!
The correct torque for the spark plug is 13.6 - 16.3 Nm ft. lbs.
Do not over-tighten.
FUEL FILTER
The fuel filter should be cleaned and inspected for damage after each twenty (20) hours of use.
The fuel filter is attached to the fuel pick-up tube inside the fuel tank. Loosen the clamp and take
out the fuel filter.
To clean the fuel filter, remove it from the fuel tube and wash it with safety solvent. Inspect and
clean the fuel tank before re-installing the fuel filter.
Always replace a defective fuel filter.
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 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.
STORAGE
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.
