Intended use

The machine is intended to be used in the way described in this
manual. If the machine is used in another way or in potentially dan-
gerous environments, e.g. explosive atmosphere or areas with
dust containing asbestos, special safety regulations must be fol-
lowed and the machine be equipped for such use.
Contact the manufacturer/ dealer for further information.
Engine
The engine is a straight six-cylinder, four stroke, direct injection
diesel with 9.6 liter cylinder volume, turbo charged, intercooled
and electronic controller fuel injection, EMS (Engine Management
System) with a cast iron block and cylinder head. Volvo engine
D12CECE2
Electrical system
The electrical system consists of engine starting system, charging
system, machine monitoring system, engine/ pump control system
and air conditioning system.
Engine speed is controlled by a rotary switch that incrementally
changes rpm, and an auto idle system that automatically engages
low idle when the machine is not operated for 5 seconds or more.
Engine condition can be checked via the VECU (Vehicle Electronic
Control Unit) by the data connection between EMS (Engine Man-
agement System) and VECU.

Hydraulic pump

The hydraulic pump assembly consists of two pumps connected
by a splined coupling. The two pumps are driven simultaneously
as the engine rotation is transmitted to the front drive shaft.
The pump consist of rotary group, swash plate group and valve
block group.
The displacement of the pump is controlled by the regulator, and
engine output power is effectively utilized by the proportional sole-
noid valve.
