Checking the Engine Oil Level
Service Interval: Before each use or daily
1. Park the machine on a level surface.
2. Disengage the PTO, turn the ignition key to off, and
remove the key.
3. Wait for all moving parts to stop before leaving the
operating position and then chock or block tires.
4. Clean around the oil dipstick (Figure 28) so that dirt
cannot fall into the filler hole and damage the engine.

5. Unscrew the oil dipstick and wipe the end clean
(Figure 28).
6. Slide the oil dipstick fully into the filler tube, but do
not thread onto tube (Figure 28).
7. Pull the dipstick out and look at the metal end. If the
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 and run the engine; engine damage can
result.

Changing the Oil
Service Interval: Every 100 hours
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 ensure 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. Place a pan below the drain. Rotate oil drain valve to
allow oil to drain (Figure 29).
6. When oil has drained completely, close the drain
valve.
Note: Dispose of the used oil at a recycling center.

7. Slowly pour approximately 80% of the specified oil
into the filler tube (Figure 28).
8. Check the oil level; refer to Checking the Engine Oil
Level.
9. Slowly add the additional oil to bring it to the Full
mark.
Changing the Oil Filter
Service Interval: Every 200 hours
Note: Change the oil filter more frequently when the
operating conditions are extremely dusty or sandy.
1. Drain the oil from the engine; refer to Changing the
Engine Oil.
2. Remove the old filter and wipe the filler adapter
gasket surface (Figure 30).
