4-6-1 Battery handling
(T218341-075-0E)
This machine uses two 12V batteries connected in series with a 24V negative earth. Observe the following precautions
when handling the batteries.
1) When handling the battery system, wear a protective eyewear, protective gloves, and long-
sleeved working clothes.
2) The battery electrolyte used is dilute sulfuric acid, so keep it away from your eyes, skin,
clothing and any metal components. If it comes into contact with any of them, wash it away
with large amounts of water. (In case of personal contact, consult a doctor after washing.)
3)
The batteries generate flammable hydrogen, so do not use flame or other source of ignition
near the batteries.
In particular take care when welding.
4)
Before inspecting/servicing the batteries or servicing the electric system, be sure to turn off
the starter switch and turn the battery disconnect switch to the OFF position "
○
" for safety
operation.
5)
Before welding, be sure to turn off the starter switch and turn the battery disconnect switch
to the OFF position "
○
" for safety operation. Failure to do so could cause the electronic
device to malfunction.
6) The DEF pump continues to operate for 5 minutes after the engine stops. Do not turn the
battery disconnect switch to the OFF position "
○
" or remove the battery cable. Doing so
could cause blockage in the DEF lines. Before you turn the battery disconnect switch to the
OFF position "
○
" or remove the battery cable, wait for at least 5 minutes after the starter
switch is set to the "OFF" position.
7) When detaching the battery cable, always begin with the negative terminal and when
reattaching the battery cable, begin with the positive terminal. Take care to connect the
terminals correctly.
8)
Handle the batteries with care. In particular do not charge them near flame or a source of
ignition and do not dispose of them in fire as an explosion could result.
9) Never take the batteries apart or make holes in the casing.
Any resulting leakage could cause dangerous corrosion and personal injury.
10) When recharging the batteries, dismount them from the machine, remove all bungs and place
them in a well-ventilated area.

NOTE
This excavator is equipped with the machine management system. Because the system unit operates continuously
using the power supply circuit, it is continuously consuming power from the battery.
Consequently, it can deplete the battery if the engine has not been operated for a long time. Therefore, about
twice a month, idle the engine for at least 30 minutes, with the accelerator dial set to medium or higher speed.
Run the engine more often as the battery ages, due to the diminished charge capacity.
