Safety Precautions
NOTICE
If the fuel filter/water separator is positioned higher
than the fuel level in the fuel tank, water may not
drip out when the fuel filter/water separator drain
cock is opened. If this happens, turn the air vent
screw on the top of the fuel filter/water separator 2 -
3 turns counterclockwise.
Be sure to tighten the air vent screw after the water
has drained out.
NOTICE
• When the engine is operated in dusty conditions,
clean the air cleaner element more frequently.
• Never operate the engine with the air cleaner
element(s) removed. This may allow foreign
material to enter the engine and damage it.
NOTICE
The maximum air intake restriction, in terms of
differential pressure measurement, must not
exceed 0.90 PSI (6.23 kPa; 635 mmAq). Clean or
replace the air cleaner element if the air intake
restriction exceeds the above mentioned value.
NOTICE
It is important to perform daily checks.
Periodic maintenance prevents unexpected
downtime, reduces the number of accidents due to
poor machine performance and helps extend the
life of the engine.
NOTICE
If the oil pump must be replaced, replace it as an
assembly only. Do not replace individual
components.
NOTICE
Do not loosen or remove the four bolts retaining the
fuel injection pump drive gear to the fuel injection
pump hub. Do not disassemble the fuel injection
pump drive gear from the hub. Correct fuel injection
timing will be very difficult or impossible to achieve.
NOTICE
The starter motor can be damaged if operated
continuously longer than 10 seconds while
performing the no-load test.
NOTICE
Do not short-circuit the charging system between
alternator terminals IG and L. Damage to the
alternator will result.
NOTICE
Do not connect a load between alternator terminals
L and E. Damage to the alternator will result.
NOTICE
Do not remove the positive (+) battery cable from
alternator terminal B while the engine is operating.
Damage to the alternator will result.
NOTICE
Do not turn the battery switch OFF while the engine
is operating. Damage to the alternator will result.
NOTICE
Do not operate the engine if the alternator is
producing unusual sounds. Damage to the
alternator will result.
NOTICE
If the engine coolant pump must be replaced,
replace the engine coolant pump as an assembly
only. Do not attempt to repair the engine coolant
pump or replace individual components.
