ENGINE OIL (CHECK DAILY)
1. When checking or adding oil, place the compressor so
the engine is level.
2. Pull the engine oil dipstick from its holder.
3. Determine if engine oil is low. Oil level should be
between the upper and lower limit (Figure 50) on the
dipstick.
Figure 50. Dipstick Engine Oil Level
4. If oil level is low, add correct amount of engine oil to
bring oil level to a normal safe level (See Recommended
Viscosity Grades, Table 10).
5. Allow enough time for any added oil to make its way
to the oil pan before rechecking.
NOTICE
DO NOT
run the engine with the air cleaner removed
or without an element.

MAINTENANCE (ENGINE)
CHANGING ENGINE OIL AND FILTER (500 HOURS)
Change the engine oil and filter every 500 hours. Refer to
Table 10 for recommended oil viscosity.
1. Prepare an oil collector to drain the oil into.
2. Remove the oil filler cap while draining the oil to
allow the oil to drain easily.
3. The engine oil drain valve is located underneath the
trailer frame (street-side). Place the valve knob in the
OPEN
position (Figure 51) to drain the engine oil.
Figure 51. Draining Engine Oil
4. After oil is sufficiently drained, place the drain valve
knob in the
CLOSED
position
5. Using a filter wrench, turn the engine oil filter
counterclockwise to remove.
6. Clean sealing surface on engine where filter mounts.
7. Coat the seal (Figure 52) of the new oil filter with clean
engine oil.
