WARRANTY NOTICE
The warranty on these engines and/or power train
components shall not apply to any failure that results
from an unauthorized adjustment of the fuel injection
system.
Any attempt to increase the engine horsepower by
increasing engine r.p.m. above its rated maximum, or
by other means, not only affects traveling speeds but
affects the life of matching parts and voids the com¬
pany responsibility as outlined in the warranty.
INJECTION PUMP (Air Bleeding)
A
CAUTION
Always keep the air vent plug on the fuel
injection pump closed except when bleeding
system, or it may cause the engine to stop.
If the engine will not start after bleeding the fuel pump,
bleed the air further in the system as follows. (See
Figure 37.)
1. Loosen the air vent plug.
2. Turn ignition key switch to "ON" position to
activate fuel pump.
3. Tighten the air vent plug.

engine is stopped and is not hot. Broken
fuel lines can cause fires.
A
CAUTION
When the fuel lines are disconnected, plug
them at both ends with clean cloth or paper
to prevent dirt from entering the lines. Dirt in
the lines can cause fuel injection pump mal¬
function.

found worn or damaged before two years, replace
or repair immediately.

CLEANING THE FUEL FILTER CUP
A

and injection nozzle are subject to quick
wear. To prevent this, be sure to clean the
fuel filter cup periodically.
Clean the fuel filter every 100 hours.
This should not be done in the field, but in a clean
place so as to prevent dust intrusion.
