4. The hand hose is now ready for use. Use the auxiliary
engine throttle to control the amount of vacuum.
Note: If a straight drop into a catch basin is required, hang
the tube directly over the hole to operate in a straight
vertical position.
Note: When using the hand hose in or around water, do
not hold the end of the nozzle completely under the water
surface. Doing so will result in the loss of suction.
Danger: Never vacuum ammable liquid. Fire and
explosion may occur.
Re-seating the hand hose
1. Unlatch the hose from the hose door.
2. Use the hand hose door latches to close the suction
door opening.
3. Swing boom back towards truck
4. Re-attach the straps that hold the hose and aluminum
nozzle to the support.
5. Hook up the cords that hold the hose and tube to the
brackets.
Hopper Drain (if equipped)
The hopper drain is located toward the rear of the hopper.
It can be used to drain liquid from the hopper, such as rain
water. This reduces load weight during wet weather and
allows longer dumping intervals.
Note: Local rules and regulations may require that liquid
picked up by the sweeper be removed at the dump site.
Hopper Deluge (if equipped)
