USING THE LOW-PRESSURE WATER PUMP
Unless the ground is wet, always use the dust suppression sprays.
Before using the dust suppression system, ensure that there is sufficient
water in the water tank. Select the water spray configuration you
require, according to the intended sweep pattern. This will start when
the Sweep Master switch is operated (in Sweep Mode) to deploy the
selected configuration.
Press the appropriate switches on the sweeper panel to start the water
spray for each item of sweeping equipment as follows:
Side-brush & Suction Box
- To start either or both the left
hand or right hand spray nozzles, press the appropriate side-
brush/suction nozzle water switches. The red LED will
illuminate to confirm the feature is active.
Widesweep Brush
- To start the widesweep spray nozzles
press the widesweep water switch. The red LED will
illuminate to confirm the feature is active.
LUBRICATION
The main bearings are ‘sealed-for-life’ and require no lubrication,
however, on some pumps the crankcase void is provided with a grease
nipple (the schedule on Page 21 gives frequency of applications).
DRAINING
1.
It is vital that the strainer and pump are totally drained whenever
the air temperature is expected to fall to 0°C or below. If allowed
to freeze it is likely that damage will be incurred.
2.
Drain the water tank and open the drain valve (Fig. 7). Switch on all
sprays and run the Hardi water pump until the systems runs dry.
