ACTION WHEN PROXIMITY SWITCH HAS FAILED 6
WARNING
When the following procedure is used to disconnect the connector of the proximity switch and then con-
nect it to another connector, the PPC (proportional pressure control pilot) lock will always remain
released (the machine can move), regardless of the operation of the fuel quick charge.
This change in the combination of the connectors is a temporary measure to enable the machine to be
moved to a safe place. After moving the machine, contact your Komatsu distributor immediately and ask
for repairs to be carried out.
The machine can move, so this is extremely dangerous. For this reason, do not use the fuel quick charge
to fill with fuel when the combination of the connectors has been changed.
If it is necessary to add fuel before the repair of the proximity switch has been completed, add fuel
through the fuel filler at the top of the fuel tank. For details, see “Check Fuel Level, Add Fuel (3-164)“.
NOTICE
When the changing the combination of the connectors, be careful not to mistake the connections.
1. Turn the starting switch to the OFF position, remove the key, wait for approx. 1 minute, then remove the nega-
tive (-) terminal of the battery.
