Engine Maintenance
Servicing the Engine Oil
The crankcase must be filled with approximately 20 fluid
ounces (0.6 l) of the proper viscosity oil before staring.
The engine uses any high-quality oil having the American
Petroleum Institute - APl - “service classification" SE
or higher. Oil viscosity - weight - must be selected
according to ambient temperature.
Figure 30
illustrates the
temperature/viscosity recommendations.
Figure 30
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
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 L mark on the dipstick, add oil to bring the
oil level to the H mark.
Do not overfill.
If the oil level is
between the H and L marks, no oil addition is required.
1.
Remove the transport wheels (if installed).
2.
Position the mower so the engine is level and clean
around the oil level gauge (
Figure 31
).

3.
Remove the oil level gauge by rotating it
counterclockwise (
Figure 31
).
4.
Wipe the oil level gauge clean and insert it into the
filler port. Do not screw the gauge into the port. Then
remove and check the level of the oil. If the level is low,
add only enough oil to raise the level until it is between
the H and L marks on the gauge (
Figure 31
). Check
the level of the oil. Do not overfill.

5.
Install the oil level gauge and wipe up any spilled oil.
Changing the Engine Oil
Service Interval:
After the first 20 hours
Every 50 hours
1.
Start and run the engine for a few minutes to warm
the engine oil.
2.
At the rear of the machine, place a drain pan under the
drain plug (
Figure 31
). Loosen the drain plug.
3.
Push down on the handle to tip the mower and engine
backward, allowing all the oil to run into the drain pan.
4.
Install the drain plug and refill the crankcase with the
specified oil; refer to
(page )
.
5.
Wipe up any spilled oil.
6.
Dispose of the used oil properly. Recycle as per local
codes.
