Engine Maintenance
Engine Oil
The crankcase must be filled with approximately 20
fluid ounces of proper viscosity oil before staring. The
engine uses any high-quality oil having the American
Petroleum Institute - APl - “service classification" SF,
SG, SH or SJ. Oil viscosity - weight - must be selected
according to ambient temperature. Figure 21 illustrates
the temperature/viscosity recommendations.
Figure 21
Note:
Using multi-grade oils (5W-20, 10W-30, and
10W-40) will increase oil consumption. Check the oil
level more frequently when using them.
Checking the Engine Oil Level
Service Interval:
Before each use or daily
1. Position mower so the engine is level and clean
around oil level gauge (Figure 22).

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 until it is between the H and L marks
on the gauge (Figure 23). Recheck level of oil. Do
not overfill.

4. Reinstall oil level gauge and wipe up any spilled oil.
Changing the Engine Oil
Service Interval:
After the first 8 hours
Every 50 hours
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
(Figure 22). Remove drain plug.
