HOW TO OPERATE CARRIER
• Warning lamp for alternator (for
charging)
• Pilot lamp indicating preheating engine
The lamp lights when something is wrong
with the charging system while the engine is
running
In case where the lamp lights during opera-
tion, stop the crane work immediately and
move the crane to a safe place to stop the
engine running.
Check the belt for tightness and damage.
Check the electric wiring to alternator and
relays for loose connection and/or poor con-
tact.
The lamp lights when the starter switch is at
“
HEAT ” (preheat) position.
It indicates that electric current is flown
through the glow plug.
Holding the starter switch at “
HEAT ” (pre-
heat) position allows the lamp to go out in
about 15 seconds to inform that preheating
has been completed.
