ENGINE ADJUSTMENTS
ADJUSTING THE DRIVE BELT
The engine's drive belt is located under the engine. To
access the belt, for inspection and/or adjustment, remove
the cover as shown. Inspect the belt for wear along the edges
and for proper belt tension (belt should be tight).
The belt tension can be checked by measuring the
spring length. . ..

The lubricating system is a pressure feeding system using an
oil pump. The engine oil is drawn from the oil sump by the
oil pump, which drives the oil, under pressure, through the
oil filter and various lubricating parts in the engine. The oil
then returns to the oil sump to repeat the continuous cycle.
When the oil pressure exceeds the specified pressUre, the oil
pushes open the relief valve in the oil pump and returns to
the oil sump, keeping the oil pressure within it's specified
range.
NOTE:
A newly starter (cold) engine may have an oil
pressure up to 40 psi. A warmed engine can have an oil
pressure as low as 30 psi. Oil pressure will vary depending
on the load placed on the generator.

TESTING OIL PRESSURE
To test the, oil pressure, remove the oil switch and install a
mechanical oil pressure gauge, in it's place, it win b,e
necessary to cOl.1nect the two switch wires together for the
engine to run. After warming up the engine, with the engine
speed at 2200 rpm, read the oil pressure gauge.
OIL PRESSURE: between 30 and 40 psi at 2200 rpm
