- E-ECU (engine rpm control)
The display unit shows information, e.g machine
status, control lamps, gauges, settings and
information/warning lights. A buzzer is integrated in
the I-ECU to warn the operator in addition to some
warning lights.
To select various functions there are two instrument
panels with a keypad, switches and controls, see

.
Most of the relays and fuses are grouped in the
electrical box under the operator’s seat.
Cab
The cab is approved as a protective structure
according to the following standards:
- TOPS (Tip-Over Protective Structure), ISO
12117 / EN13531
- ROPS (Roll Over Protective Structure), ISO
3471-1
- OPG (Operator Protective Guard) Level 1 on top,
ISO 10262
The OPG level 2 is available as an option.
These tests are based on the heaviest machine
weight configuration, unless otherwise stated.
If any part of the cab’s protective structure is
affected by plastic deformation or rupture, the cab
must be replaced immediately.
The cab is featured with heating and ventilation.
The side window can be opened and used as exit
in case of emergency.
Never carry out any unauthorised alterations to the
cab without first, through a dealer, having discussed
the alteration with personnel at the Volvo
Construction Equipment Engineering Department.
This department will decide whether the alteration
may cause the TOPS-, ROPS- and OPG-approval
to become void.
Hydraulic system
Closed circuit hydraulic load-sensing system,
allowing full independence of the individual
movements.
