limiter cap. The limiter cap cannot be removed without breaking the
pilot screw.

Engine Speed
Generators require a fixed engine speed to maintain the correct
voltage. Engine speed is controlled by a governor which automatically
adjusts to varying loads on the engine to maintain a constant speed.
There is no throttle control.
To set the engine to the proper speed:
Turn the speed adjusting screw
(b)
in or out to obtain a no-load speed.
See
Technical Data
.
NOTICE
:
Setting the engine speed too high or too low may damage
tools and other appliances attached to the generator.
