The Unloader Valve (1)will allow for the removal of fine dirt

and dust from the canister body (3) without disassembly.

While in operation, this valve will suck closed at 1/3 to 1/2

throttle.

• With the engine shut off, squeeze the valve by hand to

release dust and debris.

• In very dusty operating conditions, the valve may have

to be opened every 2 to 3 hours.

Remove the air cleaner cover and make a general

inspection of the entire assembly. If it is unusually dirty or if

dirt build-up is easily visible on the inside of the canister

body, the entire assembly, including the inlet hose, must be

removed from the carburetor and engine.

With the air cleaner removed from the engine, and with the

cartridges and gaskets removed, wash the hard parts with

cleaning solvent and blow them dry with compressed air. DO

NOT wash the air cleaner cartridges.

NOTE: If canister gaskets are broken or missing, BOTH air

cleaner elements MUST be replaced.

Inspect and clean the primary air cleaner cartridge (5)

assembly every 25 hours. Replace the paper element yearly

or every 250 hours, whichever comes first.

The outer cartridge is cleaned by rolling and "tapping" it on a

hard surface. If the paper pleats are punctured or torn, the

element must be replaced.

Replace the inner cartridge (6) yearly or every 250 hours

whichever comes first.

IMPORTANT: DO NOT attempt to clean the secondary

element. This filter element must be replaced if it is

unusually dirty or damaged.

NOTE: Operation in dusty conditions may require more fre-

quent maintenance of the primary and secondary air cleaner

cartridges.

CAUTION: Do not use pressurized air to clean

paper element.

FUEL SYSTEM SERVICE

CAUTION: Fuel vapors are explosive and

flammable. Do not smoke while handling fuel.

Keep fuel away from flames or sparks. Shut off

engine before servicing. Always work in a

well-ventilated area. Clean up spilled fuel

immediately.

Be sure the engine is stopped, the steering

control levers are in the park position and the

key is removed before making these repairs.

Be sure to inspect the fuel lines periodically.

The lines are subject to deterioration and wear.

Fuel could leak out onto a running engine and

cause a fire.

WARNING: Improper use of solvents can

result in fire or explosion. Do not use gasoline

or low flash point solvents to clean the fuel filter

and/or the fuel pump. Clean only in a

well-ventilated area away from sources of

sparks or flame, including any appliances with

a pilot light.

IMPORTANT: Special care should be taken when the fuel

lines are removed for maintenance or repair. Close both

ends of the fuel line with a piece of paper or a clean cloth to

prevent dust or dirt particles from contaminating the fuel.

Even a small amount of dust or dirt can cause premature

wear or failure of fuel components.

The fuel line connections are composed of rubber and they

will age regardless of the service period. If there is any

deterioration of the fuel lines or clamps, replace them.

Check the fuel filter regularly. If it is clogged by debris or

contaminated with water, replace it.

The fuel filter cannot be disassembled. If the fuel filter

becomes clogged, replace it with a new one.

Park the machine safely in a well-ventilated area.

Allow to cool.

Compress hose with clamp between tank and filter.

Use care not to damage or puncture hose.

4. Disconnect the hose clamps (1) from the fuel filter (see

figure 22).

5. Slide the fuel line off of both ends of the fuel filter (2).

6. Install the new fuel filter paying close attention to the

flow direction (3) noted on the fuel filter.

7. Remove clamp.

The fuel pump can not be disassembled. If the fuel pump

fails, replace it with a new one.
