DUST SUPPRESSION / VACUUM
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, place drive
lever in neutral, set parking brake, turn off
machine, and remove key.
ADJUSTING / REPLACING THE NOZZLE FLAP
Check the nozzle flap and adjustment knob for
wear and damage every 450 hours of operation.
Replace the nozzle flap when it is approximately
12 cm (5 in) in length.
1. Start the machine, place the machine into
Work Mode 1, and set the vacuum fan speed
to 2200 rpm.
2. Operate the machine and listen for the nozzle
flap vibration. It should be possible to hear the
flap vibration inside the cab, but the noise
should not be so excessive that it disturbs
persons in areas near the machine.
NOTE: Little or no flap vibration is necessary for
light sweeping (light litter). More flap vibration may
be necessary for heavier sweeping (wet sand).
3. Turn the adjustment knob clockwise to
increase the flap height and vibration and
counterclockwise to decrease the flap height
and vibration.
4. Lock the adjustment knob when finished
making adjustments.
5. Operate the machine and listen for flap
vibration. Repeat procedure if additional
adjustments are necessary.
