7.6 Engine Oil Change
Regular oil changes are necessary to maintain a
strong running engine. Change the oil at 500 hour
intervals (or every year if annual operating hours
do not exceed 500). Allow the machine to cool
prior to service. Wear safety glasses, safety gloves
and any other items necessary to ensure your
safety while performing maintenance or service.
To change engine oil:
1. Shut the machine down according to the procedure in section 5.13 and
allow the machine to cool thoroughly. Open the hood and side panels.
2. Lower the access covers beneath the engine to access the oil drain and
filter.
3. Remove the oil drain plug (item 1, fig. 7.6-1) from the bottom of the pan.
4. Drain the oil into a suitable catch container.
5. Remove the engine oil filter (item 2, fig. 7.6-1).
6. Apply fresh oil to the upper two oil filter seals only, (lower seal and engine
sealing surface must be clean and dry) and install the new filter (fig. 7.6-3).
7. Using a 1/2” ratchet and appropriate extension, torque the new oil filter to
29.5 Lb. ft (40 Nm) from the bottom through the chassis access opening.
8. Reinstall the oil drain plug as found upon removal and tighten.
9. Refill the engine to capacity at the location labeled 3 above with oil as
specified in chapter 3, Technical Data.
10. Re-secure the access covers as found upon removal, close hood and side
panels. Dispose of the used oil and filter according to mandates.
Oil and machine components can be HOT! Allow the machine to cool
thoroughly prior to performing maintenance or service to avoid the possi-
bility of burns.
