d) “A” Checks and Operations (10 Hours or Daily).
(1) Engine.
a
Check Crankcase Oil Level.
CAUTION
DO NOT
overfill.
DO NOT
operate the engine with oil level below the lower bar or
above the upper bar on the dipstick.
(i)
Check oil level daily with oil gauge dipstick.
(ii)
Oil level should not be checked until 3 to 5 minutes after engine shutdown. Keep oil
level as near the upper bar as possible.
b
Drain Fuel Lubricity Filter/Pre-Filter Element
The life of the fuel pump and injectors can be extended if the operator drains about a cup of
fuel from the fuel pre-filter element to remove water and sediment before starting the engine
each day.
CAUTION
BE SURE to prime and bleed the fuel system after draining the filters, replacing filter
element, or if the fuel tank has run empty. Failure to do so can cause engine-starting
problems.
(i)
Provide a container for catching drained fuel.
(ii)
Open the drain valve on the fuel/water filter by turning it counterclockwise.
(iii)
Drain the filter until clear fuel is visible.
(iv)
Tighten the drain valve.
(v)
Safely dispose of drained fuel.
(vi)
Purge air from fuel system if necessary.
c
Check Coolant Level
Check coolant level daily or at each fuel fill interval. Investigate for cause of any coolant loss.
WARNING
Cooling system is pressurized. To avoid personal injury, DO NOT remove radiator
cap when engine is hot.
d
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.
