projectiles can cause severe injury
or death. Loose hardware can cause
the hardware or pulley to release from
the generator set engine and can
cause personal injury. Retorque all
crankshaft and rotor hardware after
servicing. Do not loosen the crankshaft
hardware or rotor thrubolt when making
adjustments or servicing the generator
set. Rotate the crankshaft manually in
a clockwise direction only. Turning the
crankshaft bolt or rotor
counterclockwise can loosen
hardware.
Servicing the generator set when it is
operating. Exposed moving parts
can cause severe injury or death.
Keep hands, feet, hair, clothing, and
