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. Remove the key.
2. Clean around the oil dipstick (Fig. 25) so dirt cannot
fall into the filler hole and damage the engine.
3. Unscrew the oil dipstick and wipe the metal end clean
(Fig. 25).
4. Thread the oil dipstick fully onto the filler tube
(Fig. 25). 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.

Changing/Draining Oil
1. Start the engine and let it run five minutes. This warms
the oil so it drains better.
2. Park the machine so that the drain side is slightly lower
than the opposite side to assure the oil drains
completely.
3. Disengage the PTO and set the parking brake.
4. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
5. Slide the drain hose over the oil drain valve.
6. Place a pan below the drain hose. Rotate oil drain valve
to allow oil to drain (Fig. 26).
7. When oil has drained completely, close the drain valve.
8. Remove the drain hose (Fig. 26).
Note: Dispose of the used oil at a recycling center.
