Introduction
Introduction:
ALTO's newly designed Scrubtec 795, 784 & 770 automatic scrubbers are efficient and superior floor cleaning
machines. The Scrubtec 795 uses two brushes or pads to scrub a path 97 cm wide. The Scrubtec 784 uses
two brushes or pads to scrub a path 84 cm wide. The Scrubtec 770 uses two brushes or pads to scrub a path
71 cm wide. A squeegee wipes the floor while the vacuum motor removes the dirty solution from the floor - all
in one pass.
The Scrubtec 795, 784 & 770 automatic scrubbers come complete with six - 6 volt batteries, five battery
connector cables, two battery cables, either two brushes or two pad drivers, and one operator's manual.

MACHINE CONTROL PANEL SRUBTEC 770 S, 784 S & 795 S
Key Switch (See Figure #1, Item "A")
The key switch turns "ON" the power to the control panel. "0" is "OFF" and "I" is "ON".
Traverse Speed Switch (See Figure #1, Item "B")
The speed control varies from low to high speed. To increase the speed, turn the knob to the right. To decrease the
speed, turn the knob to the left.
Brush Up/Down Switch (See Figure #1, Item "C")
The brush switch has two positions: "Up" positions the brushes up; "Down" positions the brushes on the floor. The
brush motors start when the brushes are down and the traverse switch is depressed.
Increase Brush Pressure Switch (See Figure #1, Item D)
This switch is used to increase the brush pressure. Increased brush pressure may be required when stripping or
cleaning heavily soiled floors. To increase brush pressure, first lower the brushes by pressing the brush up/down
switch (Item "C") to the down position. This will lower the brushes to the normal scrub position. To increase brush
pressure, press and hold the switch (Item "D") until the desired brush pressure is reached or the brush deck stops
moving downward. To reposition the brush pressure to normal scrub, press the brush up/down switch (Item "C") to
the up position and after the brush deck is completely raised, then return the switch to the down position for normal
scrub.
Solution Control Knob (See Figure #1, Item "E")
The solution control knob regulates the flow of cleaning solution to the floor. To increase the flow turn the knob
clockwise. To decrease the flow, turn the knob counter-clockwise.
Forward Switch (See Figure #1, Item "F")
The forward switch turns the traverse motor "on" and if the brush motors are in the down position, it also activates the
brush motors and solution control module. Either the right or the left switch can be used.
Reverse Switch (See Figure #1, Item "G")
The reverse switch, when used in conjunction with one of the forward switches, causes the machine to reverse
direction. The reverse speed is 70% of the forward speed.
Charge / Battery Meter (See Figure #1, Item "H")
The charge/battery meter indicates the amount of charge that is left in the batteries while the machine is in use. When
the battery pack gets too low the red light will begin flashing and the brush/pad motors will shut off.
Circuit Breakers (See Figure #1, Item "I"-"M")
The circuit breaker reset buttons are located on the control panel. The breakers are located as follows: Item I & J Brush Motors (35A); Item K - Traverse Motor (30A); Item L - Vac Motor (25A); Item M - Actuator Motor, Brush Head (5A)
If a circuit breaker trips, determine which motor is not operating and turn the key switch "OFF". Wait five minutes and
push the reset button back in. Turn the key switch "ON", and try again. An authorized service person should be
contacted if the breaker trips again.
Hour Meter (See Figure #1, Item "N")
The hour meter indicates the number of hours the machine has operated. It runs only when the machine is moving
forward or reverse.

The squeegee will lower and the vacuum motor will turn on when the switch is placed in the lower position. To raise the squeegee, place the switch in the up position. The vacuum motor will stop, after a short delay, when the switch is placed in
the up position.
The middle switch position is used for the one touch control. The squeegee will raise and lower and the vacuum will
turn on and off automatically when the one touch control function is used. NOTE: The squeegee switch must be in
the middle position for the squeegee and vacuum to operate properly with the one touch feature.
Brush Up/Down Switch (See Figure #2, Item D)
To lower brush head, push the brush switch in the down (+) position. To increase brush pressure, continue to push
the brush switch in the down (+) position until the desired pressure is reached or until brush head travel stops. The
brush motors will start and solution will flow (provided the solution is turned "ON") when the machine begins to
traverse. To raise the brush head, push the brush switch in the up (-) position until the brush head travel stops or
desired position is reached.
Solution Flow Control (See Figure #2, Item "E")
The solution flow switch regulates the flow of chemical solution to the floor. To increase the flow, push the solution
flow switch in the down (+) position until desired flow is reached. To decrease the flow, push the solution flow switch
in the up (-) position until the desired flow is reached. To shut off the solution, push the solution flow switch in the up
(-) position until no indicators are visible on the display. NOTE: DO NOT run dry! NOTE: No solution will flow when
the machine does not traverse.
Forward Switch (See Figure #2, Item "F")
The forward switch turns the traverse motor "on" and if the brush motors are in the down position, it also activates the
brush motors and solution control module. Either the right or the left switch can be used.
Reverse Switch (See Figure #2, Item "G")
The reverse switch, when used in conjunction with one of the forward switches, causes the machine to reverse
direction. The reverse speed is 70% fo the forward speed.
One Touch (See Figure #2, Item "H")
The one touch button is a green button that lowers and raises the brush head and squeegee with one touch. NOTE:
For more information about the one touch feature see the section "How to Operate the Machine".
LCD Display (See Figure #2, Item "I")
The main display indicates the state of battery charge, brush head, solution and squeegee status. It will also display
machine run hours and error codes. NOTE: When the battery charger gets too low the battery display will begin
flashing and the brush/pad motors will shut off.
Display Button (See Figure #2, Item "J")
Pressing the black display button will toggle between the main machine functions and the hour meter. The hour
meter indicates the number of hours the machine has operated. It displays brush motor, vacuum motor, traverse

Battery Maintenance
The electrical power to operate the machine comes from the
storage batteries. Storage batteries need preventive maintenance.
WARNING: Working with batteries can be dan-
gerous. Always wear eye protection and protective clothing when
working near batteries.
NO SMOKING!
To maintain the batteries in good condition, follow these
instructions:
1. Keep the electrolyte at the correct level. The correct
level is between 6.35mm below the bottom of the tube
in each cell and above the tops of the plates. Check
the level of the electrolyte each time you charge the
batteries. See figure #7.
NOTE: Check the level of electrolyte prior to charging the
batteries. Be sure the plates in each cell are covered with
electrolyte . Do not top off the cells prior to charging the
battery. Electrolyte expands during charging. As a result,
the electrolyte could overflow from the cells. Always top off
the cells with distilled water after charging.
CAUTION: Irreversible damage will occur to
the batteries if the electrolyte level
does not cover the plates. Keep the
electrolyte at the correct level.
Correct fill level
Figure #7
CAUTION: Machine damage and discharge
across the tops of the batteries can
occur if the batteries are filled
above the bottom of the tube in
each cell. Do not fill the batteries
up to the bottom of the tube in each
cell. Wipe any acid from the
machine or the tops of the batteries. Never add acid to a battery
after installation.
CAUTION: Tap water may contain contami-
nants that will damage batteries.
Batteries must be re-filled with distilled water only.
2. Keep the tops of the batteries clean and dry.
Keep the terminals and connectors clean. To clean the
top of the batteries, use a damp cloth with a weak
solution of ammonia or bicarbonate of soda solution.
To clean the terminals and connectors, use a terminal
and connector cleaning tool. Do not allow ammonia or
bicarbonate of soda to get into batteries.
3. Keep the batteries charged.

How To Charge The Batteries
WARNING: Charging the batteries in an area
without adequate ventilation could
result in an explosion. To prevent an
explosion, charge the batteries only
in an area with good ventilation.
WARNING: Lead acid batteries generate gases
which could explode. Keep sparks
and flames away from batteries. NO
SMOKING!
To charge the batteries, follow this procedure:
1. Make sure the key switch is in the “OFF” position.
2. Before charging the batteries, the battery compartment
needs to be vented. To vent compartment, tip up the
recovery tank until it locks in the open position (see
figure #8). To close the tank, pull up on the arm and then
slowly lower the tank to the closed position.
CAUTION: Before raising tank, be sure tank is
empty.
WARNING: Do not operate or perform
maintenance on the machine while
the recovery tank is in the open
position. The tank can be
accidentally bumped and it may slam
shut.
Figure # 8
3. Put the charger on a flat surface. Make sure the vents
on the sides are at least two inches away from walls
and other objects. Make sure there are no objects near
the vents on the bottom of the charger.
4. Disconnect the battery pack connector from the
batteries.
5. Connect the DC connector on the charger to the battery
pack connector. See figure #8A.
6. Connect the battery charger AC cord located at the rear
of the machine to a 10 amp (min) 230V properly
grounded wall receptacle.
7. Observe indicator light to ensure the charging process
has started. Flashing light(s) indicates that the
batteries are being charged. Steady on green light
indicates the batteries are fully charged.
NOTE: Make sure you plug into a circuit that is not loaded by
other equipment. Wall breakers may be tripped and no
charge will occur.
WARNING: Never charge a GEL battery with an
unsuitable battery charger. Carefully
follow the instructions given by the
manufacturer of the batteries and
battery charger.
NOTE: To prevent permanent damage to the batteries, avoid
their complete discharge. Never leave the batteries
completely discharged, even if the machine is not being
used. When recharging the batteries, keep the recovery tank
open. After every 20 recharging cycles, check the level of the
electrolyte and if necessary top off with distilled water.
