A Do not start the engine with an auxiliary battery
if excavator battery is frozen.
A Do not connect the black jumper cable to the
negative (-) terminal of the excavator battery.
BObserve Following Guidelines when
Starting with an Auxiliary Battery
1. Bring the helping machine with the same battery
voltage as near as possible to the excavator.
THE MACHINES MUST NOT COME IN CONTACT
WITH EACH OTHER.
2. Bring the levers and pedal of both vehicles in the
neutral position and put the lock lever in the "Lock"
position.
3. Wear eye protection and rubber gloves.
4. Open the side cover. (See "Opening / closing of the

6. Cover the battery opening with a cloth. Make sure that
the cloth does not touch the battery terminals.
7. Connect the terminal of the red jumper cable with the
plus (+) terminal of the low battery and connect the
other end of the cable to the plus (+) terminal of the
auxiliary battery.
8. Connect the black negative cable to the minus (-)
terminal of the auxiliary battery.
9. Connect the other end of the black cable (coming from
the auxiliary battery) to the excavator frame as far
away as possible from the low battery.
10.Start the engine of the helping machine and let it run
for a while. Start the excavator with the low battery.
