PRELUBE SKIP FUNCTION WHEN STARTING IN EMERGENCY
3
(If equipped)
If an abnormality occurs in the prelube system and the prelube does not work properly, it may be impossible to
start the engine.
If this happens, change the connection of the emergency start connector to start the engine without carrying out
the prelube operation.
WARNING
q
Always turn the key in starting switch (1) to the OFF
position before handling the emergency start connec-
tor.
q
Change the emergency start connector only if the pre-
lube does not work properly because of some abnor-
mality in the system. Do not use this system to start
the engine if the prelube system is normal.
q
When using the emergency start connector to start the
engine without carrying out the prelube operation, first
move the machine to a safe place, stop the machine,
turn the parking brake switch ON, then ask your
Komatsu distributor to carry out repairs.
