crankcase. Before starting engine, fill

with oil. Do not over-fill. Do not run the

engine with a high or low oil level as

this can cause engine damage. If you

have further questions regarding the

engine, please refer to the engine

manual included with the unit.

Check the engine oil level with the

1. Remove the filler cap/dipstick and

wipe it clean.

2. Insert and remove the dipstick without

screwing it into the filler neck. Check the

oil level shown on the dipstick.
3. If the oil level is low, fill to the

edge of the oil filler hole with the

recommended oil.

Always use SAE 10W-30 oil.
Oil crankcase capacity: 0.6L.

4. Reposition the oil gauge dipstick and

tighten it by turning clockwise.

5. Engine oil should be changed after the

first 5 hours, then every 50 hours. Failure

to change engine oil will void engine

warranty.
