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

2. Remove oil level gauge by rotating it
counterclockwise.
3. Wipe oil level gauge clean and insert it into filler port.
Do not screw into port. Then remove and check level
of oil. If level is low, add only enough oil to raise level
to bottom of filler opening. Recheck level of oil. Do
not overfill.
4. Reinstall oil level gauge and wipe up any spilled oil.
Changing the Oil
1. Start and run engine for a few minutes to warm the
engine oil.
2. Place a drain pan at rear of machine under drain plug
(Fig. 29). Remove drain plug.
3. Push down on handle to tip mower and engine
backward, allowing more oil to run into drain pan.
4. Install drain plug and refill crankcase with proper oil;
refer to Checking the Oil Level, page 24.
Servicing the Air Cleaner

More frequent cleaning is required when mower is
operated in dusty or dirty conditions.
1. Make sure wire is off spark plug.
2. Remove wing nuts securing air cleaner cover to air
cleaner and remove cover. Clean cover thoroughly
(Fig. 30).

foam element to dry.
C. Saturate element with clean engine oil. Squeeze
