ENGINE OIL MAINTENANCE

Engine Oil Specification

Use premium quality 4-stroke engine oil with an
API Service Classification of at least SG. A SAE
multigrade viscosity of 10W-30 is suitable for
use in ambient temperatures of up to 40°C. For
temperatures above 40°C, a multigrade viscosity of
15W-40 is recommended.
NEVER use 2-stroke engine oil either directly in the
engine or mixed with the fuel.
Mineral based, semi-synthetic or fully synthetic oils
may be used, but different types of oils should not
be mixed together. The engine oil supplied originally
with the generator is a mineral type with SAE 1 5W-
40 viscosity.

Checking Engine Oil

NOTICE
Always maintain proper engine oil level. Failure
to maintain proper engine oil level can result in
severe damage to the engine and/or shorten the
life of the engine.
Always use the specified engine oil. Failure to use
the specified engine oil can cause accelerated
wear and/or shorten the life of the engine.
Engine oil level should be checked before every use.
1. Always operate or maintain the generator on a
flat surface.
2. Stop engine if running.
3. Let engine sit and cool for several minutes (allow
crankcase pressure to equalize).
4. Remove the oil access cover on the rear of the
generator (see Figure 14). With a damp rag,
clean around the oil fill plug.
5. Remove oil fill plug by unscrewing it anti-
clockwise (see Figure 15).
6. Check oil level:
• Acceptable Oil Level – Oil surface is at the
bottom lip of the oil fill plug opening (see
Figure 16).

• Low Oil Level – Oil surface is below the
bottom lip of the oil fill plug opening. Add oil
as required.
• Too High Oil Level - Oil flows out when the oil
fill plug is removed. Allow the excess oil to
drain out into a waste oil container.
