TRANSIT / WORK MODES SWITCH
Transit Mode (top position) is for moving between
job sites. The machine can reach speeds up to 40
km/h (25 mph) when in this mode. The front
wheels automatically track out to provide more
stability when the machine exceeds 5 km/h
(approximately 3 mph). The brushes raise and
stop rotating, the vacuum head raises, and the
vacuum fan stops operating.
Work Mode 1 (middle position) is for sweeping.
The machine can reach speeds up to 12 km/h
(8 mph) when in this mode. If the front wheels are
in the out position, they will automatically track in
when the machine exceeds 5 km/h (approximately
3 mph). The brushes lower and begin rotating, the
vacuum head lowers, and the vacuum fan begins
operating.
Work Mode 2 (bottom position) is for moving short
distances between work areas and driving over
curbs or speed bumps. The machine can reach
speeds up to16 km/h (9 mph) when in this mode.
The brushes raise and stop rotating, the vacuum
head raises, and the vacuum fan stops operating.
The machine automatically provides increased
traction.
BRUSH SPEED KNOB
Turn the Brush speed knob clockwise to increase
the speed of both brushes and counterclockwise
to decrease the speed of both brushes.

OPERATION
15
636 9006280 (9--09)
VACUUM FAN SPEED KNOB
Turn the Vacuum fan speed knob clockwise to
increase the vacuum and counterclockwise to
decrease the vacuum.
NOTE: For normal operating conditions the
vacuum fan speed should be set to below 2400
rpm.
VACUUM FAN SPEED BOOST
The vacuum fan speed can be set to above 2400
rpm (boost) for a short time (5 minutes). A
countdown bar appears on the MDM display.
Reduce the vacuum fan speed to less than 2400
rpm before the countdown bar expires. It must be
reduced for at least 30 seconds or the machine
must be stopped and the drive lever placed in
neutral for five seconds before returning to
vacuum fan speed boost. If not, an audible alarm
will sound at the end of the five minutes, the fan
will shut off, and a warning message will appear
on the MDM display.
To reset the vacuum fan speed boost limiting
system, stop the machine and place the drive
lever in neutral. Restart the machine and turn the
vacuum speed to below 2400 rpm.
This vacuum fan speed boost is available for only
five 5--minute intervals per hour. After five boost
periods, the vacuum fan speed will be limited to
2300 rpm for the rest of the hour

WATER SWITCH (DUST SUPPRESSION)
Turn the water switch to position 0 in areas where
dust suppression is not necessary. Neither the
brush head spray jets nor the vacuum tube spray
jets operate in this mode. The CloudMaker nozzle
continues to rotate to keep the spray head clean,
but does not use water.

where full dust suppression is necessary. The
CloudMaker nozzle, brush head spray jets, and
vacuum tube spray jet operate in this mode.
Turn the water switch to position 2 in areas where
some dust suppression (wet sweeping) is
necessary. Only the brush head spray jets and
vacuum tube spray jets operate in this mode. The
CloudMaker nozzle continues to rotate to keep
the spray head clean, but does not use water.
WATER FLOW CONTROL KNOB
Turn the Water flow control knob clockwise to
decrease the amount of water supplied to the
brush jets and counterclockwise to increase the
amount of water to the brush jets.
NOTE: To operate only the CloudMaker and
conserve water, turn the water switch to position 1
and the water flow control knob to the minimum
flow setting to turn off the water to the brush
spray jets.
