Checking the Oil Level
Note: Check oil when engine is cold.
1. Disengage the power take off (PTO) and turn the
ignition key to off. Move levers to neutral locked
position and apply parking brake. Remove the key.
2. Clean around the oil dipstick (Fig. 37) so dirt cannot
fall into the filler hole and damage the engine.
3. Pull the oil dipstick and wipe the metal end clean
(Fig. 37).
4. Slide the oil dipstick fully into the filler tube. Pull the
dipstick out and look at the metal end (Fig. 37). 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. Do not run engine
with oil below the low mark because the engine may be
damaged.

Changing the 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. Disengage the power take off (PTO), set
the parking brake, and turn the ignition key to off.
Remove the key.
3. Place a pan below the oil drain. Rotate oil drain valve
to allow oil to drain (Fig. 38).
4. When oil has drained completely, close the drain
valve.
Note: Dispose of the used oil at a certified recycling
center.
