ADD ENGINE OIL

Page 14

1.Place generator on a flat, level surface.

2.Clean area around oil fill and remove yellow 
oil fill cap/dipstick.
3.Wipe dipstick clean.

NOTE:

The engine is equipped with a low oil shut-off and
will stop when the oil level in the crankcase falls
below the threshold level.

NOTE:

We consider the first 5 hours of run time to be
the break-in period for the unit. During the break
in period stay at or below 50% of the running
watt rating and vary the load occasionally to allow
stator windings to heat and cool. Adjusting the
load will also cause engine speed to vary and help
seat piston rings. 

CAUTION

The unit is equipped with a low oil shutdown.If 
the oil level becomes lower than required,the 
sensor will activate a warning device or stop the 
engine.
If generator shuts off and the oil level is within 
specifications, check to see if generator is sitting 
at an angle that forces oil to shift. Place on an 
even surface to correct this. If engine  fails to 
start, the oil level may not be sufficient to 
deactivate low oil level switch. Make sure the 
sump is completely full of oil.

5.Replace oil fill cap/dipstick and fully tighten.
6.Oil level should be checked prior to each use 
or at least every 8 hours of operation

.

 Keep oil 

level maintained.

4.Using oil funnel, slowly pour contents of 
provided oil bottle into oil fill opening to the 
"H" mark on dipstick. Be careful do not 
overfill. Overfilling with oil could cause the 
engine to not start or hard starting.
