The objective of this manual is to ensure that the machine is operated correctly and performs the service of cleaning level floor sur-
faces. Therefore, we advise you to follow the instructions it contains scrupulously since the manufacturer accepts no
responsibility for damage to persons, or things, or damage to the machine if the machine is not operated the way described in this
manual or if the maintenance and safety instructions are not fully complied with.
The instructions provided in this manual do not replace the safety instructions and technical data for installation
and operation directly applied on the product, nor do they replace the safety standards current in the country of installation
and the rules dictated by normal common sense.
The operator or maintenance worker must advise a person in authority of any faults or deterioration which could
affect the original safety of the machine.

Solution Tank: The solution tank is located under the lid, at
the front of the machine, with the filling-funnel M1 in an acces-
sible position for easy re-filling.
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 24 gallons (100 liters). Always use the products and the dilu-
tion quantities recommended by the seller. The solution tank
may be drained by removing the plug on the bottom left side of
the tank or by vacuuming the solution out into the dirty water
tank with a 1-1/2 “ vacuum hose attached where the squeegee
hose normally fits Never use foamy detergents. Use defoamer if
excess foam develops.
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, open the ball valve M2, emptying
dirty water into the proper drain conforming to local regula-
tions. For sludge clean-out, open the port by loosening both
knobs.
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 pressing pedal M3. 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 natural 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. When cleaning very shiny, smooth or
floors with grout removal of the rear (shorter)squeegee blade
is recommended.
Battery installation and charging: The batteries must be
inserted in the special compartment provided under the lid.
Apply a layer of vaseline to the terminals and connect in series
as shown on page 18. Make sure that the terminals are correct-
ly tightened. The battery charger must be installed in a well
ventilated place where it is planned to leave the machine. The
charger is provided with a cable for connection to the mains,
normally 120v/60HZ. Check that the voltage corresponds to
the voltage indicated on the battery charger. Do not use an
extension cord to power the charger. To charge the batteries,
connect the connector of the machine batteries M 5 to the con-
nector of the battery charger. The Powr-Flite battery charger
will automatically regulate the voltage to the batteries and will
switch itself off when the batteries have been fully charged.
CAUTION: A) Make sure key switch is turned “OFF” and bat-
tery connector is unplugged from machine before peforming
any maintenance procedures. B) Battery acid can cause burns.
When working on or around batteries, wear protective clothing and
safety glasses. Remove metal jewelry. Do not lay tools or metal
objects on top of batteries. C)Charging batteries give off explo-
sive fumes and harmful (corrosive) fumes.
NO SMOKING OR OPEN FLAMES OR SPARKS. Make sure
the charger has turned off before disconnecting it from the
batteries. Charge batteries in a well-ventilated area with the lid
raised and in locked position while the batteries are charging.

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.
Starting up and operation: Disconnect the batteries from the
battery charger and connect to the machine. Then:
• Turn master switch M6 to position 1 and press
switches M7 and M8.
•Lower the brushes by turning knob M9 clockwise.
Maximum setting is #10. Only use the pressure setting
that effectively performs the cleaning desired for the
longest run time and fastest operation.
•Lower the squeegee by pressing pedal M3.
•Set the detergent solution supply to minimum by raising
the adjusting knob M12.
• Release the brake by squeezing the small lever.
•Press down the handle M10 to drive forward.
When the handle is released the machine stops.
•Adjust the speed of advance by adjusting knob M11.
• Finally, adjust the correct supply of the detergent in
relation to the amount of dirt and speed of advance by
means of lever M12; this is a matter of experience.
At this point the machine is ready to carry out the operations of
scrubbing and drying at the same time. Single vacuum motor
operation may be all that is necessary for daily scrubbing. To
operate one vacuum open and lock the autoscrubber lid.
Locate the fuse panel P1 attached to the back frame behind the
vacuum motors. Pull and open the first fuse door from the left
side of the fuse housing bank.
CAUTION: Make sure key switch is in the “OFF” position
before installing pad.
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.
CAUTION: A) Loose objects on the floor can become danger-
ous projectiles if struck by the high-speed pad. Remove them
before oper at in g this machine. B ) Keep machine moving to
prevent damage to finish or floor. C ) These machines are
designed for level floor operations only. DO NOT OPERAT E
ON RAMPS OR INCLINES greater than 2% grade
unless adequate personnel are available for assistance.

Squeegee: Every week, check the blades of the squeegee and
wash them carefully. Then replace them in the correct working
position (see above). 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. Inspect the squeegee vacu-
um path for obstructions.
The pad driver or brush must be in good working condition
because it is the component which removes the dirt.
To replace the block, pad or brush:
• Turn off the machine by placing the key in the off
position
•Lift the brush up by turning the knob M9 to the off
“O” position
•Open the spring lever M15 or fold up the vinyl
splash guard. Access from your right side, facing the
front of the scrubber.
•Rotate the brush by hand until the M19 spring
rings are reached. Closing the M19 spring rings
together by fingers (like scissors) drops the brush.
•Rotate driver/brush 180° and firmly pull it out from
the scrubber.
A selection of brushes for specific purposes is available. Pad
drivers should be installed with the chosen pad. Bla c k for strip-
ping, Gre e n for deep scrub, B l u e for cleansing and R ed for light
scrub.
Water collection tank: This tank should be cleaned every
week.
1 ) Lift and lock the lid.
2 ) Remove the vacuum motor straps M13 and lift the
vacuum motors out.
3) Thoroughly clean the filter or replace with a new filter.
4) Remove the float cage assembly and clean off the float ball
and assembly. Inspect free movement of the float ball.
5) Thoroughly flush out the tank by spraying water into the
tank through the openings allowing the drainage through
the valve or sludge port M2. The sludge door may be
removed by unscrewing the 2 knobs.
6) Before replacing the door clean the door housing and
the gasket M28.
7) Carefully replace all components and make sure the
gaskets are seated.
Batteries: Check the level of the electrolyte liquid by carefully
removing plugs from top of battery and topping off with distilled
water, when the level drops below the plates of the battery.
Keep the batteries clean and dry with antistatic cloths. When
charging the batteries lift the top lid of the machine to allow the
gas which is generated to escape. This gas can cause explo-
sions in closed environments and, therefore, it is advisable
to carry out battery charging in well-ventilated environments.
