Engine Oil
The engine is filled with full synthetic oil (API SJ/CF 5W-30).
This allows for system operation in the widest range of
temperature and climate conditions.
We recommend the use of Briggs & Stratton
5W-30 full synthetic engine oil. Other high-quality detergent
oils are acceptable if classified for service SJ or higher. Do
not use special additives.

Adjust Valve Lash

The valve lash must be checked every 100 hours of
operation. Measure the valve clearance with the engine cold.
To adjust the valve lash, proceed as follows:
1. Push the ON/OFF Switch on the back of the generator to
the "OFF" (0) position.
2. Remove utility power to generator to de-energize the
battery charger.
3. Unlock and open the roof as described in the Access
Panels section of this manual.

Synthetic oil meeting ILSAC GF-2,
API certification mark and API
service symbol with "SJ/CF ENERGY
CONSERVING" or higher, is an
acceptable oil at all temperatures.
Use of synthetic oil does not alter
required oil change intervals.
Removing the engine intake screen in the battery
compartment such that the crankshaft nut is
accessible. Care must be taken when reassembling
this screen using the self tapping screws as over-
torqueing will strip out the partition material.
OR remove the front alternator outlet air scoop
by removing the four screws that secure it. The
crankshaft may be rotated via the aluminum
alternator fan. Care should be taken not to damage
the fan, and to reinstall the alternator outlet air scoop
in the proper orientation.
