Checking the Engine-Oil Level
Service Interval: Before each use or daily
Note:
Check the oil when the engine is cold.
Important:
If you overfill or underfill the engine
crankcase with oil and run the engine, you may
damage the engine.
1. Park the machine on a level surface, disengage
the PTO, and engage the parking brake.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
Note:
Ensure that the engine is cool so that the
oil has had time to drain into the sump.
3. To keep dirt, grass clippings, etc., out of the
engine, clean the area around the oil-fill cap and
dipstick before removing it (
Figure 16 ).
