ENGINE OIL MAINTENANCE

Engine Oil Specification

1. 

Only use the engine oil specified in Figure 17.

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 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.  With a damp rag, clean around the 

oil fill plug/dipstick.

5. 

Remove oil fill plug/dipstick (see Figure 18 below).

Figure 18 - Oil Fill Plug/Dipstick

6.  Check oil level: When checking the engine oil, 

remove the oil fill plug/dipstick and wipe it clean. 
Thread the oil fill plug/dipstick all the way back in and 
then remove and check the oil level on the oil fill plug/
dipstick. 

•  Acceptable Oil Level

 – Oil is visible on the 

crosshatches between the H and L lines on the oil 
fill plug/dipstick (see Figure 19).

•  Low Oil

 – Oil is below the L line on the oil fill 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 flat surface.

2.  Stop engine if running.

3. 

Let engine sit and cool for several minutes (allow 
crankcase pressure to equalize).

4. 

Thoroughly clean around the oil fill plug/dipstick.

5. 

Remove oil fill plug/dipstick and wipe clean.

6.  Select the proper engine oil as specified

 

in Figure 17.

7. 

Using the supplied funnel, slowly add engine oil to 
the engine. Stop frequently to check the level to 
avoid overfilling.

8.  Continue to add oil until the oil is at the correct level. 

See Figure 19.

9. 

Replace the oil fill plug/dipstick.
