NOTE:
The maximum engine speed for ‘full-load, up-hill’ sweeping should not exceed
1800 rpm. Operating the engine beyond this level consumes more fuel without
giving further performance advantage.
5.
Select the desired sweeping equipment combination (including
Beacon) by operating the appropriate switches on the control
panel.
6.
Select Suction Fan ON and then deploy the sweeping equipment
by operating the Brush Master Switch.
NOTE:
The suction fan speed is preset to reach maximum RPM at normal engine
operating speed (1380 rpm), therefore, suction performance cannot be
improved by increasing engine speed beyond the values stated in
paragraph 4.
7.
Select FORWARD on the FORWARD/REVERSE lever and release the
handbrake.
NOTE:
In Sweep Mode, the vehicle is controlled, principally, by means of the throttle.
The brakes are only necessary when manœuvring in very confined areas.
Releasing the throttle pedal at sweeping speeds produces marked
deceleration with very little over-run, affording precise control while sweeping.
8.
When Reverse is selected in Sweep Mode, all sweeping equipment
in use will stop and lift automatically. This will revert to the selected
sweeping configuration when NEUTRAL or FORWARD is re-selected.
9.
Upon completion of the sweeping run, operate the Brush Master
Switch to stop and raise the sweeping equipment permanently to
the stowed position (the selected sweeping configuration will
remain active and may be redeployed by returning this switch to
the ON position).
10.
Turn the suction fan OFF.
REDUCING NOISE LEVELS & FUEL CONSUMPTION
Although the most efficient engine operating speed is 1380 rpm, there are
times when it is possible to reduce engine speed, thereby reducing noise
levels. This is most beneficial when sweeping at night, or in areas sensitive
to noise pollution.
Sweeping with reduced engine speeds can be achieved most
satisfactorily when sweeping light or sparsely distributed materials.
Experience will enable the operator to vary the selected engine speed
according to sweeping conditions.
It should be noted that the operator also benefits from reduced noise
levels within the cab and that any reduction in engine speed, also results
in a corresponding reduction in fuel consumption.
