Servicing the Engine Oil
Service Interval: Before each use or daily—For
Kawasaki engines—check the
engine-oil level.
Every 100 hours—For Kawasaki
engines—change the engine oil (more
often in dirty or dusty conditions).
Every 200 hours—For Kawasaki
engines—change the engine-oil filter
(more often in dirty or dusty conditions).
Engine-Oil Specifications
Oil Type: Detergent oil (API service SF, SG, SH, SJ,
or SL)
Crankcase Capacity:
•
Kawasaki FX751 and FX801 engines—2.3 L (78
fl oz) with a filter change; 2.1 L (71 fl oz) without
a filter change
•
Kawasaki FX921 and FX1000 engines—1.9
L (64 fl oz) with a filter change; 1.7 L (57 fl oz)
without a filter change
Viscosity: See the table below.
Note:
Although 10W-40 engine oil is recommended
for most conditions, you may need to change oil
Figure 47
viscosity to accommodate atmospheric conditions.
Using 20W-50 engine oil in higher ambient
temperatures can reduce oil consumption.
Checking the Engine-Oil Level
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, etc., out of the
engine, clean the area around the oil-fill cap and
dipstick before removing it
