3. Carefully slide the primary filter over the safety

seated by pushing on the outer rim while

Servicing the Engine Oil
Service Interval: Before each use or daily
Every 100 hours (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: 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
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.
