DO NOT fill the hopper through the hopper door.
Fill the rear dust suppression water tank using a 30mm hose – about 130 litres.
Move the 3 way valve, to the “Hopper” position – located above the
rear left hand suspension spring/damper (swing out the rear water
tank).
If a pressure washer is fitted, turn the high pressure 3 way valve on
left hand side of the machine to “Street Washer” position – open the
LH access panel
.
Fold down the spray bar at the front of the machine and lock in place.
Ensure that the FAN switch on the right hand switch column is switched to OFF and that the brush speed
control is set to the zero speed.
Start the engine, engage Sweep mode and switch on Street Washer (switch is on
the header). Engage forward drive on the Forward/Neutral/ Reverse lever switch.
The sprays on the spray bar will start spraying – it may take 1 or 2 minutes to obtain a full spray pattern with
the fan sprays meeting. If full spray is not available within 2 minutes, switch off the Street Washer and check
for blockages and correct valve position.
DO NOT
run the street washer pump for periods in excess of
2 minutes
with no water passing through the
pump, as permanent damage to the pump will result.
Use the left hand Brush control joystick on the control arm to slew the spray bar from side to side. Operating
the spray bar at an angle will wash debris to one side of the washed path.
The spray bar fan sprays should just meet at the ground. If there are
gaps
between the sprays,
raise
the
spray bar using the rotary height adjuster at the rear of the spray bar suspension bracket.
The water in the hopper will provide about 25 minutes of street washing. When the hopper becomes empty,
this will be indicated by the sprays becoming intermittent. If the street washing task is not complete an extra 7
or 8 minutes of street washing can be obtained by using the water in the dust suppression water tanks (there
are 2 of these connected together). The water is accessed by swinging open the rear water tank and turning
the 3 way valve to “Water Tank”.
Close the rear water tank. The street washer pump will now draw water from the dust suppression water
tanks.
