Checking the Engine Oil Level
Service Interval: Before each use or daily
Note: The best time to check the engine oil is when the
engine is cool before it has been started for the day. If it has
already been run, allow the oil to drain back down to the
sump for at least 10 minutes before checking. If the oil level
is at or below the 'add' mark on the dipstick, add oil to bring
the oil level to the 'full' mark. DO NOT OVERFILL. If the
oil level is between the 'full' and 'add' marks, no oil addition
is required.
1. Park the machine on a level surface.
2. Turn the ignition key to off, and remove the key.
3. Clean around the oil dipstick (Figure 20) so that dirt
cannot fall into the filler hole and damage the engine.

4. Unscrew the oil dipstick and wipe the end clean (Figure
20).
5. Slide the oil dipstick fully into the filler tube, but do not
thread onto tube (Figure 20).
6. 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. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
4. Place a pan below the drain. Rotate oil drain valve to
allow oil to drain (Figure 21).
2. Filler tube
Note: A hose may be inserted onto the drain valve to
direct the oil flow. The hose is not included with the
machine.
5. When oil has drained completely, close the drain valve.
Note: Dispose of the used oil at a recycling center.

6. Slowly pour approximately 80% of the specified oil
into the filler tube (Figure 20).
7. Check the oil level; refer to Checking the Engine Oil
Level.
8. 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 22).
