Returning the machine to SWEEP mode
Ensure the hopper is empty of water. If a significant amount of water (more than 50 or 60mm) still remains in
the hopper, drain it out by deploying the “wet weather” drogue on the front left hand side of the hopper.
Tip the hopper and fold up and stow the fan ducting seal diaphragm.
Ensure that the 3 way valve (above the suspension spring) is set to “WATER TANK” to prevent dirty water
from the hopper accidentally entering the dust suppression water circuit.
Ensure the STREET WASHER switch on the header switch panel is switched to OFF.
Switch the fan switch to ON.
Select SWEEP mode, set up fan and brush speeds and commence sweeping.
Using the Pressure Wash Lance (where fitted)
Ensure that the front 3 way valve (located behind the left hand access panel) is set to “PRESSURE LANCE”
and that the rear 3 way valve is set to “WATER TANK”.
Check that there is sufficient water in the rear water tank.
Select SWEEP mode and check that the engine speed is above 1800rpm.
Switch the Pressure Lance switch to “PRESSURE LANCE”.
Ensure that the handbrake is set and that the Forward/Neutral/Reverse control is set to Neutral.
Open the left hand access panel and withdraw the pressure lance and unreel sufficient hose. Using both
hands hold the pressure lance firmly and pointing the spray nozzle towards the ground, press the trigger.
DO NOT
run the high pressure pump for sustained periods with the pressure lance trigger closed, as the
pump will be on high pressure bypass and will eventually overheat.
