Engine Speed
See Graphic: wc_gr000114
All generators require a fixed engine speed to maintain the correct
voltage output. Engine speed is controlled by a governor which
automatically adjusts to varying loads on the engine to maintain a
constant speed of 3600 – 3700 rpm.
Testing Engine Speed
Measure the engine speed using a tachometer with no load applied to
the generator. The engine must be running at 3700 ± 50 rpm. Voltage
output is directly related to engine speed. A slow engine will reduce
voltage. Refer to the Operator’s Manual for engine speed adjustment.
The generator is designed to produce no output if engine rpm
falls 10% or more below the required speed (approximately 3200 –
3400 rpm).
Setting Engine Speed
Setting the engine speed requires the adjustment to the governor.
To set the engine to the proper speed:
Turn the engine speed adjusting screw (a) in or out to obtain a no-load
speed of 3700 rpm.
CAUTION: Setting the engine speed too high or too low may damage
tools and other appliances attached to the generator.
