Waste Water Tank Full
The vacuum shut o󰀨 system stops the
airow when the top waste water tank is
full. A oat ball rises as the water level
rises, when the waste water tank is full
the oat ball blocks the vacuum hole to
prevent any liquid entry.
The vacuum motor will continue to run,
there is an audible di󰀨erence in the sound
when the waste water tank is full.
A secondary shut o󰀨 will engage if the
water exceeds the oat ball shutting o󰀨 the
vacuum until the water level is lowered.
Located in your waste-water (top) tank is
a full tank switch, this stops your machine
from working once the waste-water
reaches its maximum limit.
Sometimes the switch gets clogged
and blocked, clean to ensure correct
operation.

To operate, select forward and depress the accelerator pedal.
Vacuum pick-up and water ow will turn on if selected and providing the brush and oor tool are in
the lowered position, the machine will move forward.
Clean water is dispersed evenly via ‘THRU- FEED’ scrubbing brushes.
The waste water is then retrieved by the suction oor tool.
Overlap each scrubbing path by 10cm to ensure an even clean.
After stopping, let the vacuum motor run for 10 seconds to collect any water left in the vacuum
hose, then switch the vacuum motor o󰀨.
On heavily soiled oors use a ‘double scrub’ technique.
First pre-scrub the oor with the oor tool in the raised position, allow the chemicals time to work,
then scrub the area a second time with the oor tool lowered.
If your machine leaves streaks on the cleaned oor,
either clean the oor tool blade or adjust blade height
for optimum performance.
The optional o󰀨-aisle cleaning kit gives added exibility
to the operator.
The kit can be used to clean hard to reach / inaccessible areas.
Remove the vacuum hose from the oor tool and attach to the
o󰀨-aisle kit.
To operate the vacuum, press the vacuum switch on.
Note: Return the hose to the oor tool once nished using
