Oil Alert System
The Oil Alert system is designed to prevent engine damage
caused by an insufficient amount of oil in the crankcase. Before
the oil level in the crankcase can fall below a safe limit, the Oil
Alert system wilt automatically stop the engine (the engine
switch wilt remain in the ON position). The Oil Alert system
should not take the place of checking the oil level before each
use. If the engine stops and wilt not restart, check the engine oil
level (see page 14) before troubleshooting in other areas.
Ground Terminal
The generator ground terminal is con-
nected to the frame of the generator, the
metal non-current-carrying parts of the
generator, and the ground terminals of
each receptacle.
Before using the ground terminal, consult a qualified elec-
trician, electrical inspector or local agency having jurisdic-
tion for local codes or ordinances that apply to the intended
use of the generator.
