Fitting 5
Drive pump supply pressure
approx. 25 bar with sweeping mode
(engine idling)
Fitting 3
Drive pump with reverse travel:
approx. 315 to 330 bar
Hub motors
in rear wheels
Change transmission oil for the multi-
disc brakes in the rear wheel hub
motors after 150 hours of operation,
then every 600 hours.
rotate hub motor until drain plug
points down
open drain plug, drain oil
rotate drain hole to a turn drain hole
to a horizontal position.
fill transmission oil until housing is
full; equals approx. 0.5 litres of e.g.
Mobiloil Mobilgear 630.
Gauge outlets (fittings)
The M16x2 fittings allow gauging of
the following pressure levels at an oil
temperature of approx. 50°C:
Fitting 1
Sweeping attachment and hopper:
approx. 180 bar max.
Fitting 2
Drive pump with forward travel:
approx. 315 to 330 bar
Fitting 4
Suction turbine: operating pressure
approx. 115 bar with sweeping mode
(engine speed 2,600 rpm)
65
Hydraulic system
of power steering,
hopper lift, sweeper
and suction turbine
Three pumps flanged to the travel
drive pump supply the suction turbine,
sweeper, power steering and hopper
lift with pressurized oil. The pump
located at the travel drive pump sup-
plies the suction turbine, whereas all
other functions are driven by the
second pump.
Power steering
the power steering circuit is supplied
with pressurized oil by the same pump
as the for hopper lift and sweep-ing
attachment. A valve gives preference
to the power steering circuit all the
time.
Power steering won't work unless
engine is running.
Note :
with the engine not running,
high steering power will be required.
Toe-in: 0 to 2 mm
check as required and every 600 h.
