Nozzle Adjustment
In order to maximise the performance of the machine it is important that a working clearance
is maintained between the nozzle rubbers and the road surface. The following settings are
recommended as a guide although some conditions may require a tighter front nozzle setting.
Adjustment is carried out with the Maxigap/Varagap in the closed position.
Lower Nozzle for Adjustment
To lower the nozzle first, turn on the ignition and then turn off the axillary engine. All nozzles
will now lower to the ground.
Rear Nozzle Rubber
Recommended ground clearance 8-10mm.
Adjustment
Raise or lower the carriage wheels as required by loosening the two securing nuts (D)
Front Nozzle Rubber
Recommended ground clearance 35-40mm.
Adjustment
The nozzle opening angle can be adjusted by loosening the hand wheel (A) and then
moving the lever (B) forwards to increase, or backwards to decrease.
The rear nozzle rubber should always be approximately 8-10mm from the ground to allow
for the road camber. An average gap setting between the front nozzle rubber and the ground
has been found to be 35-40mm for most sweeping conditions. These adjustments may
become necessary as nozzle rubbers and tyres wear.
There must always be sufficient extension (75-100mm) capability in the nozzle trunking and
the nozzle lift cylinder to ensure that the nozzle does not become suspended when passing
over road surface depressions. The attachment of the nozzle lift cylinder to the trunking
bracket may be adjusted downwards by the clamped ‘U’ bolt (E).
Additional adjustment is provided to alter the draw bar height/position. Normally the centre
hole is utilised. Repositioning setscrew (C) into a lower hole raises the front of the nozzle,
or into a higher hole lowers the front of the nozzle.
The Maxigap feature (F) opens the nozzle aperture to allow for the ingestion of bulky
objects.
CAUTION
The use of Needle stick gloves is recommended when working with this equipment.
