Battery Disconnect Switch

IMPORTANT: Never attempt to turn the battery
disconnect switch OFF while engine running. Failure
to do so may damage the electrical system.
d
WARNING: After stopping the engine, the DEF pump
keeps operating to return the DEF in piping to the DEF
tank. Do not turn the battery disconnect switch OFF
while pump running. Failure to do so may damage the
SCR system.
The battery disconnect switch is different from the engine
start key switch. When the battery disconnect switch is turned
OFF, the electrical system will completely be isolated from
the battery. No current will flow through the entire electrical
system.
Before turning the battery disconnect switch OFF, be sure
to turn the key switch OFF and wait 5 minutes or more after
the engine stops before turning battery disconnect switch.
Because controllers communicate with each other and record
information after the engine stops, battery power is required
for a minimum of 5 minutes.
Use the battery disconnect switch only for the following
purposes; otherwise, turn it ON.
 Before maintaining and repairing the electrical system
 Before storing the machine for long period (Discharge
prevention)
 Theft prevention after use.
Turn the battery disconnect switch ON before starting the
engine.
The battery disconnect switch is located inside of the battery
box.
