GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should malfunction or breakdown, grounding provides
a path of least resistance for electric current to reduce the risk electric shock. This machine is
equipped with a cord having an equipment -grounding conductor and grounding plug. The plug
must be inserted into an appropriate outlet that is properly installed and grounded in accor-
dance with all local codes and ordinances.
WARNING: Improper connection of the equipment-grounding conductor can result in a risk
of electric shock. Check with a qualified electrician or service person if you are in doubt as to
whether the outlet is properly grounded. Do not modify the plug provided with the appliance - if
it will not fit the outlet, have a proper outlet installed by a qualified electrician.
This appliance is for use on a nominal 120-volt circuit, and has a grounding plug that looks like
the plug illustrated in sketch A.

Solution Tank: The solution tank is located under the lid, at the front of the machine, with the
filling-funnel M1 in an accessible position for easy re-filling.
WARNING: Always switch off and unplug the machine before filling the solution tank.
Note: Always empty the dirty water collection tank, as described in the next paragraph, before
refilling the tank with the diluted detergent solution. The solution tank has a maximum capacity of
17 gallons (30 liters). Always use the products and the dilution quantities recommended by the
seller. Always use low foam detergents. Use defoamer if excess foam develops. Remove hose
from vacuum intake and pick up defoamer directly into the recovery tank.
Water collection tank: The dirty water collection tank should be emptied, preferably each time
after use, so that the dirt does not settle there. To do this, remove the plug of the drain hose
M2, which is kept in position by a simple spring clip, and empty dirty water into the proper drain
conforming to local regulations.
Squeegee: The squeegee has the final task of completing the drying of the floor and it is very
important for it to be in the correct position. Lower the squeegee to the working position by
depressing pedal M3 as shown. Adjust the position of the squeegee by means of the knobs
M4 so that the black rubber bar is about 1⁄32” (the thickness of a business card) from the floor.
The squeegee behind this is in para rubber and must press on the floor with a certain amount
of force. After the first few hours the squeegee adjusts itself to the correct angle and drying
becomes even better. Squeegee pressure is adjusted by knob M14.

The area to be scrubbed: Debris and grit must be swept up before starting the scrubbing operation
to avoid vacuum line blockage and to permit the detergent to perform efficiently.
DO NOT OPERATE ON RAMPS OR INCLINES unless adequate personnel are available for
assistance.
Starting up and operation: Plug the machine into an outlet position allowing operation by moving
away from the outlet.
NOTE: The PAS20E is intended for use with 120V/60Hz cycle grounded circuit. Extension cords are
not recommended.
Then: • Press switches M7 and M8. • Lower the brush by pressing pedal M9. • Lower the
squeegee by depressing pedal M3. • Set the detergent solution supply to minimum by adjusting
knob M12. Experience will help with the selection of the correct solution amount. Moving outward
away from the outlet will allow the cord to be kept off of a dirty floor and also from dragging dirt
into the cleaned path. • Depress the handle (M10) to begin scrubbing with the brush. Release the
handle (M10) to stop the brush from turning.
Particularly dirty floors: Certain floors or areas may require special attention and, in some cases,
cleaning twice. Go over the floor quickly the first time, with the squeegee raised and the brush in
the working position. In this way, the detergent solution is left on the floor for a longer time and can
dissolve the heavy dirt. The second time, go over the floor more slowly with both the brush and the
squeegee lowered.

Squeegee: Every week, check the blades of the squeegee and wash them carefully. Then replace
them in the correct working position. If drying is not perfect even after the unit has been cleaned,
replace any blades which are excessively worn. If the squeegee does not pick up enough water
or streaks, lift and wipe off the blades.
Pad Driver: The pad driver or brush must be in good working condition because it is the
component which removes the dirt. To remove the brush/ pad driver from the machine: •
Depress the brush pedal (M9) to lift the brush. • With the brush in the air depress the handle
(M10) to rotate the brush.
• Release the handle and the brush will release from the machine and fall to the floor. To replace
the drive block, pad or brush: • Center the brush/pad driver under the front of the machine.•
Release the brush pedal (M9) to lower the brush drive motor on to the brush/pad driver. • Turn
the brush motor on by depressing the brush switch (M7). The brush/pad driver should lock in
place. • If the brush/pad driver does not connect, small adjustments are needed from one side
to the other to make the brush/pad driver lock in place. Brushes in tynex, poly and steel are
available on request, together with floor pads recommended for use with the pad driver. Black
for stripping, green for deep scrub, blue for cleansing and red for light scrub.
Water collection tank: This tank should be cleaned every week. Lift the lid and remove the panel
or funnel M1 of the solution tank. Remove the strap M13 and lift the vacuum motor out of its
seat. Thoroughly clean the filter and wash out the dirt deposited in the tank with a jet of water,
allowing it to drain out through hose M2. If necessary, replace filter. Replace float cage with open
side facing front of scrubber.
