Servicing the Engine Oil
Engine-Oil Specifications
Oil Type: Detergent oil (API service SF, SG, SH, SJ,
or SL)
Crankcase Capacity: 1.8 L (61 fl oz) without the oil
filter; 2.1 L (71 fl oz) with the oil filter
Viscosity: See the table below.
Note:
Although 10W-40 engine oil is recommended
for most conditions, you may need to change oil
viscosity to accommodate atmospheric conditions.
Using 20W-50 engine oil in higher ambient
temperatures can reduce oil consumption.
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 blade-control switch (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, and other debris,
out of the engine, clean the area around the
oil-fill cap and dipstick before removing it
