Engine Oil Service

Service Interval/Specification
Change oil:
After the first 8 operating hours.
After every 100 operating hours.
Note: Change oil more frequently when operating
conditions are extremely dusty or sandy.
Oil Type: Detergent oil (API service SE, SF or SG)
Crankcase Capacity: with new filter, 57–1/2 oz. (1.7 l)
without new filter, 51 oz. (1.5 l)
Viscosity: See table below
Checking Oil Level
1. Park the machine on a level surface, disengage the
power take off (PTO), chock or block tires, and turn
the ignition key to "OFF" to stop the engine. Remove
the key.
2. Clean around the oil dipstick (Fig. 23) so dirt cannot
fall into the filler hole and damage the engine.
3. Unscrew the oil dipstick and wipe the metal end clean
(Fig. 23).
4. Thread the oil dipstick fully onto the filler tube (Fig.
23). Pull the dipstick out and look at the metal end. If
oil level is low, slowly pour only enough oil into the
filler tube to raise the level to the "FULL" mark.
Important
Do not overfill the crankcase with oil
because the engine may be damaged.
