128 OPERATION
DANGER
To avoid potential fire hazard, do not
service any part of the fuel system while
smoking or in the presence of flames,
sparks or hot surfaces, or when working
on an operating engine. Failure to follow
these precautions can result in fire. To
guard against burns from direct contact
with hot fuel, wear adequate protective
clothing (face shield, heavy gloves and
apron, etc.) when working on a hot engine.
WARNING
DO NOT work near the fan with the engine
running. The engine fan can engage at any
time without warning. Anyone near the fan
when it turns on could be seriously injured.
Before turning on the ignition, be sure that
no one is near the fan.
