Avant 755i 760i

WARNING

Risk of fire - Use correct type of

cable.

When the optional block

heater is installed on the loader, a

green electric mains cable is

provided with the loader. Do not

use other types of cables. The

cable must be approved for

outdoor use. The engine block

heater A410648 is intended to

operate with electric supply of

220 - 240 V, 50-60 Hz AC power.

Do not modify the cable or use

transformers. Contact your Avant

dealer or service point for

information about other types of

block heaters.

CAUTION

Risk of electric shock and

damage to loader - Disconnect

the block heater before

operating the loader.

Make sure

to remove disconnect and store the

cable of the block heater before

moving the loader in order to

prevent damaging the cable, or its

connectors. Remove the cable

from electric mains socket. Never

leave the cable hanging on the

ground to avoid potential electric

shock.
