Maintenance

Maintenance, replacement or repair of emission control

devices and systems may be performed by any repair

establishment or individual; however, warranty repairs

must be performed by a dealer or service center autho

rized by Maruyama Manufacturing Company, Inc. The

use of parts that are not equivalent in performance and

durability to authorized parts may impair the effective

ness of the emission control system and may have a

bearing on the outcome of a warranty claim.
Maintenance on today's low-emission engines is even

more critical for longest life and best performance. par

ticularly critical are air and fuel filters, spark plug heat

range, cooling air intake area and proper gaps of coil

and plug.

Engine

Air Filter

Maintenance Interval

• The air filter should be cleaned daily, or more often

when working in extremely dusty conditions.

• Replace after every 100 hours of operation.

Air Filter

1. Loosen the knob and remove the air filter cover.

Remove the foam element and filter screen from

the air filter body.

Clean the foam element and filter screen with warm,

soapy water. Let the screen and element dry completely.

Fuel Filter

Maintenance Interval

The fuel filter should be replaced after every 100 hours

of operation.

Fuel filters needing more frequent replacement may

indicate debris in fuel tank.

Fuel Filter Replacement

The fuel filter is attached to the end of the fuel pick-up

hose inside the fuel tank.

1. Make sure the fuel tank is empty.

Remove the fuel cap.

3. Using a wire hook, gently pull the fuel filter out

through the fuel filler opening. Use caution not to

"fishhook" the fuel tube. Replace immediately if

punctured!

Grasp the fuel hose next to the fuel filter fitting

and remove the filter, but do not release the hose.

5. While still holding on to the fuel hose, attach the

new fuel filter.

Drop the new fuel filter back into the fuel tank.

7. Make sure that the fuel filter is not stuck in a cor

ner of the tank, and that the fuel hose is not dou

bled over (kinked) before refueling.
