Checking and Changing
Engine Oil
Check the oil level each time the mower is used or after
every 5 operating hours. Initially, change oil after the first
20 hours of operation; thereafter, change oil after every 50
hours of operation. More frequent oil changes are required
in dusty or dirty conditions.
Checking the Oil Level
1. Position the mower so the engine is level.
2. Clean around the oil level gauge (Fig. 29).

3. Remove the oil level gauge by rotating it
counterclockwise.
4. Wipe the oil level gauge clean and insert it into the filler
port. Do not screw it into the port.
5. Remove the gauge and check the level of the oil.
6. If the level is low, add only enough oil to raise the level
to the filler opening.
7. Install the oil level gauge and wipe up any spilled oil.
Changing the Oil
1. Start and run the engine for a few minutes to warm the
engine oil.
2. Place a drain pan at the rear of machine, under the drain
plug (Fig. 29).
3. Remove the drain plug.
4. Push down on the handle to tip the mower and the
engine backward, allowing more oil to run into the
drain pan.
5. Install the drain plug and refill the crankcase with the
proper oil; refer to Checking the Oil Level.
Servicing the Air Cleaner
Normally, clean the air cleaner after every 25 operating
hours. Clean it more frequently when the mower is
operated in dusty or dirty conditions.
1. Ensure that the wire is off of the spark plug.
2. Remove the wing nuts securing the air cleaner cover to
the air cleaner and remove the cover (Fig. 30).
3. Clean the cover thoroughly (Fig. 30).
