Servicing the Engine Oil

Change oil after the first 50 operating hours and
then every 150 operating hours thereafter.
Oil Type: High-quality detergent oil classified "API

Figure 41
Checking the Engine Oil Level
Note: Check the oil when the engine is cold.
1. Disengage the PTO, move the motion control
levers to the neutral locked position and set
the parking brake.
2. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
3. Clean around the oil dipstick (Figure 42) so
dirt cannot fall into the filler hole and damage
the engine.
4. Pull the oil dipstick out and wipe the metal end
clean (Figure 42).
5. Slide the oil dipstick fully into the tube. Pull
the dipstick out and look at the metal end
(Figure 42). If the oil level is low, slowly pour
only enough oil into the fill hole to raise the
level to the full mark.
Important: Do not overfill the crankcase
with oil because this may cause engine
damage. Do not run the engine with oil
below the low mark because the engine
may be damaged as a result.

Changing the Engine Oil
1. Start the engine and let it run for five minutes.
This warms the oil so it drains better.
2. Park the machine on a level surface.
3. Disengage the PTO, move the motion control
levers to the neutral locked position 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. Place a pan below the oil drain. Remove the
drain plug and let the oil drain completely
(Figure 46).
6. Remove the oil filler cap from the top of the
engine (Figure 44). This will help the oil to
drain.
7. Install the drain plug and tighten it to
25-1/2 ft-lb (35 N•m).
