2. Only use 4-stroke/cycle engine oil. NEVER USE
2-STROKE/CYCLE OIL. Synthetic oil is an
acceptable substitute for conventional oil.
Figure 17 - Recommended Oil
CHECKING ENGINE OIL
NOTICE
Always maintain proper engine oil level. Failure to
maintain proper engine oil level could result in severe
damage to the engine and/or shorten the life of the
engine. Always use the specied engine oil. Failure
to use the specied 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 at surface.
2. Stop engine if running.
3. Let engine sit and cool for several minutes (allow
crankcase pressure to equalize).
4. With a damp rag, clean around the
oil ll plug/dipstick.
5. Remove oil ll plug/dipstick (see Figure 18 below).
Figure 18 - Oil Fill Plug/Dipstick
6. Check oil level: When checking the engine oil,
remove the oil ll plug/dipstick and wipe it clean.
Thread the oil ll plug/dipstick all the way back in and
then remove and check the oil level on the oil ll plug/
dipstick.
• Acceptable Oil Level – Oil is visible on the
crosshatches between the H and L lines on the oil
ll plug/dipstick (see Figure 19).
• Low Oil – Oil is below the L line on the oil ll plug/
dipstick.
If oil level is below
this line it is too
low to operate.
Figure 19 - Checking Oil Level
ADDING ENGINE OIL
1. Always operate or maintain the generator
on a at surface.
2. Stop engine if running.
3. Let engine sit and cool for several minutes (allow
