Operation (cont’d)
Position the power unit on firm level ground.
Pre-Start
1. Check engine oil level. Running the engine with a
low oil level can cause engine damage. The oil alert
system will automatically stop the engine before the
engine oil level falls below safe limits. However, to
avoid the inconvenience of an unexpected shutdown, always check the engine oil level before
startup.
Refer to the Engine Owner’s Manual for correct oil
type and checking instructions.
2. Check fuel level. Refer to the Engine Owner’s
Manual for fuel recommendations.
3. Check hydraulic reservoir oil level. Fill to full level
as shown on hydraulic fluid level decal. Refer to
“Recommended Hydraulic Fluids” for correct
hydraulic fluid.
4. Check the air filter. A dirty air filter will restrict air flow
to the carburetor, reducing engine performance.
5. Verify that all current maintenance has been performed on the power unit. Refer to the “Maintenance”
section.
