DRIVE ADJUSTMENTS
CAUTION: Stop the engine, put the steering
control levers in the park position and remove
the key from the ignition before performing any
maintenance or repairs on this unit.
Steering and motion controls should be uniform during
forward and reverse motions. The steering control levers
should always return to neutral when released from the
reverse position.
AIR CLEANER
SERVICE
(FIGURE
21)
CAUTION: Touching hot surfaces can burn
skin. The engine and components will be hot
after the unit has been running. Allow the
engine and components to cool before
servicing the unit.
IMPORTANT: To prevent excessive engine wear, do not run
the engine without the air cleaner installed.
IMPORTANT: The engine is air cooled and requires a large
amount of air intake when running. Reduced air intake can
cause overheating. Always keep air intake screen and
cooling fins clean. Always keep the covers and screens in
place.
NOTE: 19hp Kawasaki engines use only a single-piece
filter (5).

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.
