A combination of micron particle water
spray jets are installed around the
sweeping system to reduce dust particle
emission. When this option is fitted it is
activated by operating the nozzle switch
and channel brush switch located on the
door controller.
Operation
The standard channel brush
water switch activates the PM10
jets (A & B).
The standard channel brush jets
are activated in conjunction with
the gutter spray switch.
Check daily that all additional
micro water jets are functioning
not blocked.
Taps are provided on spraybars (B & C) so that the operator has some adjustment if
required.

VARAGAP NOZZLE OPTION
Allows the lateral position of the channel brush to be altered whilst sweeping. Operating the
Multifuctional joystick moves the channel brush in/out from its nominal working position.
The Maxigap cylinder is replaced by a version offering a variable aperture for the nozzle. Moving
the lever up closes the nozzle, moving the lever down opens the nozzle. The length of time the
lever is held dictates the nozzle gap.
