a.
Check oil level daily with oil gage dipstick (see 1-2, Fig. 1).
b.
Oil level should not be checked until 3 to 5 minutes after engine shutdown. Keep oil level as
near the upper bar as possible.
(2)
Drain fuel prefilter (see fig. 3)
The life of the fuel pump and injectors can be extended if the operator drains about a cup of fuel
from the fuel prefilter element to remove water and sediment before starting the engine each day.
BE SURE to prime and bleed the fuel system after draining the filters, replacing
any element in the system, or if the fuel tank has run empty. Failure to do so can
cause engine starting problems.
a.
Provide a container for catching drained fuel.
b.
Open the drain valve on the fuel/water filter by turning it counterclockwise.
c.
Drain the filter until clear fuel is visible.
d.
Tighten the drain valve.
e.
Safely dispose of drained fuel.
f.
Purge air from fuel system if necessary.
(3)
Check coolant level
Check coolant level daily or at each fuel fill interval. Investigate for cause of any coolant loss.
(4)
Check for leaks and correct
At each daily start-up, check for coolant, fuel, and oil leaks. Coolant leaks may be more
noticeable when components are cold. Observe pumps, hoses, fittings, gasket connections,
etc., for signs of leakage. Correct as required.
(5)
Check air cleaner indicator
At each daily start-up, observe the air cleaner indicator light (1-3; 6, Fig. 1). If this light comes
ON
, it indicates that the air cleaner should be changed.
(6)
Check exhaust system
Visually inspect muffler and exhaust pipes for rust and signs of approaching failure. Listen for
any gasket or joint leaks.
A leaking and defective exhaust system could be a fire hazard.
(7)
Electrical (Engine)
a.
Check all lights
Check all indicating lights to be sure they will operate when they should. If any light fails to
operate, check both the lamp and its protective circuit breaker. Figure 5 lists all lamps with
their location and part number. Figure 6 lists all circuit breakers.
b.
Check alternator charging rate
Observe the 12-V DC ammeter each time the engine is started. A zero amperage reading or
extremely high reading for any length of time indicates trouble in the alternator, regulator,
battery, or interconnecting wiring.
