If fuel filter is contaminated, replace fuel filter. Inspect and clean the fuel tank before re-installing
the fuel filter.
Always replace a defective fuel filter.
COOLING FINS
Free passage of air 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.
MUFFLER AND EXHAUST PORTS
The muffler should be removed and serviced after each one hundred (100) 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 sprayer will provide maximum performance for many hours, if it is
maintained 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 BACK PACK POWER SPRAYER, 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.
Clean chemicai tank.
