HOW THE MACHINE WORKS

The Stride2 is a battery powered, self-propelled,
hard floor scrubber intended for commercial use.
The appliance applies a cleaning solution onto a
hard floor, scrubs the floor with brushes, and then
vacuums the soiled water back into the recovery
tank.

The machine's primary systems are the solution
system, scrub system, recovery system, and
directional control system.

The function of the solution system is to store
cleaning solution and deliver it to the scrub
system. The solution system consists of the
solution tank, strainer, valve and controls. The
solution tank stores cleaning solution (water and
detergent) until it is delivered to the scrub system.
The strainer protects the valve from debris. The
valve is a solenoid type valve, which controls the
delivery of cleaning solution to the scrub system.
The valve automatically prevents solution flow
unless the scrub brushes are turned on and the
machine is being propelled. The solution control
knob controls the amount of cleaning solution
delivered to the scrub system by controlling the
amount of time the valve is open.

The function of the directional control system is to
control the direction and speed of the machine.
The directional control system consists of the
directional control lever, switches, speed control
knob/potentiometer, controller and transaxle. The
directional control lever actuates switches, which
signal forward or reverse. The speed control
knob actuates a potentiometer, which signals
speed. The controller interprets the
forward/reverse signals from the switches and the
speed signal from the potentiometer to command
the transaxle to propel the machine in the
direction, and at the speed, desired.

The function of the scrub system is to scrub the
floor. The scrub system consists of two rotary
type disk scrub brushes, motors, self-adjusting
scrub deck skirt, lift actuator and controls. The
brushes scrub the floor and the motors drive the
brushes. The brush drive hubs allow the scrub
brushes to follow irregularities and changes in the
floor without loosing contact with floor. The self­adjusting scrub deck skirt controls the cleaning
solution on the floor so that the squeegee can
pick it up. The brush pressure switch controls an
actuator, which raises and lowers the scrub deck.
The brush pressure indicator corresponds to the
amp draw of the scrub brush motors to tell how
hard they are working.

The function of the recovery system is to vacuum
the soiled water back into the recovery tank. The
recovery system consists of the squeegee,
vacuum motor, filter, recovery tank and controls.
The squeegee wipes the dirty solution off the floor
as the machine moves forward. The vacuum
motor provides suction to draw the dirty solution
off the floor and into the recovery tank. The filter
protects the vacuum fan from debris and foam.
The recovery tank stores the dirty solution. The
float switch in the tank activates the recovery tank
full indicator and shuts off the vacuum motor.

BATTERIES

The batteries provide the power to operate the
machine. The batteries require regular maintenance
to keep them operating at peak efficiency.

The machine batteries will hold their charge for long
periods of time, but they can only be charged a
certain number of times. To get the greatest life
from the batteries, charge them when their charge
level reaches 25% of a full charge. Use a
hydrometer to check the charge level.

Do not allow the batteries to remain in a discharged
condition for any length of time. Never expose a
discharged battery to temperatures below freezing.
Discharged batteries will freeze causing cracked
cases. Do not operate the machine if the batteries
are in poor condition or if they have a charge level
below 25% (specific gravity below 1.155).

Keep all metallic objects off the top of the batteries,
as they may cause a short circuit. Replace worn or
damaged cables and terminals.

Check the electrolyte level in each battery cell
before and after charging the batteries. Never add
acid to the batteries, use distilled water. Do not
allow water level to fall below the battery plates.
Portions of plates exposed to air will be destroyed.
Do not overfill. Keep plugs firmly in place at all
times.

3. Wipe off the top of the batteries at least once a
week.

4. Test battery condition with a hydrometer at least
once a week.

5. Ensure that all connections are tight and all
corrosion removed.

6. Every 4 to 6 months, remove that batteries from
the machine and clean the battery cases and
battery compartment.

CHECKING BATTERY SPECIFIC GRAVITY

Use a hydrometer to check the battery specific
gravity.

Battery Check

CHECKING GRAVITY
A. Hydrometer
B. Battery

NOTE: Do not take readings immediately after
adding distilled water, if the water and acid are not
thoroughly mixed, the reading may not be accurate.

When servicing machine, avoid contact with
battery acid.

Batteries emit hydrogen gas. Explosion or fire
can result. Keep sparks and open flame away.
Keep covers open when charging.

Wear eye protection and protective clothing
when working with batteries.

Charge batteries in a well ventilated area.
BATTERY MAINTENANCE

1. When cleaning the batteries, use a solution of

baking soda and water. Do not allow the
cleaning fluid to enter the battery cells,
electrolyte will be neutralized.

2. Maintain the proper electrolyte level in each
battery cell. If a cell should accidentally
overflow, clean immediately.

Check the hydrometer readings against this chart.

SPECIFIC GRAVITY

@ 80° F (27°C)

1.265 100% CHARGED

1.225 75% CHARGED

1.190 50% CHARGED

1.155 25% CHARGED

1.120 DISCHARGED

NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 80°F
(27° C), the reading must be temperature corrected.

To find the corrected specific gravity reading when
the temperature of the battery electrolyte is other
than 80°F (27°): Add (+) to the specific gravity
reading 0.004 (4 points), for each 10°F (6° C) above
80° (27° C).
Subtract (-) from the specific reading 0.004 (4
points), for each 10°F (6°C) below 80°F (27°C).

MAINTENANCE

SCRUB BRUSHES

NOTE: All original equipment brushes are equipped
with “Perform Alert ”. This feature will tell the
operator when it is time to replace the scrub
brushes. “Perform Alert ” brushes have pre­trimmed bright yellow tufts to indicate the length of a
worn out brush. When the tufts in the scrub brush
wear to a length equal to the yellow tufts, the scrub
brushes should be replaced.

There are five different types of brushes available to
cover applications from cleaning heavily soiled floors
to polishing. A pad driver is also available to take
advantage of the many cleaning pads on the market
and further add to the flexibility of the Stride2.
Please refer to the following to assist in selecting the
proper brush or pad for the work at hand.

UNCOATED FLOORS

Aggressive Grit is a nylon fiber impregnated with

silicone carbide grit. It grinds away stain, soil, and
removes surface material.

Mild Grit is a less aggressive silicone carbide grit
suitable for cleaning medium soil conditions.
Advantages are faster ground speed than nylon
bristles on light solid applications.

Nylon is a general-purpose scrub brush with stiff
bristles. Polypropylene works well for maintaining
concrete, wood and tile floors.

FINISHED FLOORS

Blue Pads (Scrubbing) are used for heavy-duty

scrubbing and light stripping. The blue pads remove
less finish than brown stripping pads, yet will remove
black marks, stains and dirt.

Brown Pads (Stripping) are used for easy and
complete removal of old floor waxes/finishes. They
will quickly remove ground in dirt, black heel marks,
and spills. When used with the proper stripper, this
pad leaves the floor clean and ready for finishing.

The scrub brushes should be checked before each
days work for wire, string, wear and damage. The
scrub brushes should be replaced if brush bristles

are missing or if yellow Perform Alert  indicates
minimum brush length.

REPLACING OR INSTALLING SCRUB
BRUSHES

1. With the scrub deck up, turn “OFF” the machine.

FOR SAFETY: Before leaving or servicing the
machine; stop on level surface, turn OFF
machine and remove key.

2. Locate release lever on top of brush or pad

driver. Rotate release lever counter-clockwise
and the brush/pad driver will release and drop
down.

3. To reinstall, center the brush driver under the
brush drive hub. Raise until it contacts brush
driver assembly. Turn clockwise until release
lever plate locks into position.

Nylon Polish is the softest brush. It will gently clean
finished tile or terrazzo floors without removing floor
finish or floor material. Used for washing highly
polished or burnished floors.

Nylon bristles are used in a variety of applications
on coated or uncoated surfaces.

White Pads (Polishing) are used for dry polishing to
achieve a high-gloss appearance, or surface
washing on highly polished or burnished floors.

Red Pads (Buffing) are used for light-duty
scrubbing. When used with a mild detergent they
will provide surface cleaning without removing the
finish.

4-3

STRIDE2 36V (SS) 98745 11/08/99

NOTE: Check that release plate is completely
closed and pad/brush is securely attached. Damage
to driver or brush could occur.

4. Repeat the procedure for the opposite side of
machine.

MAINTENANCE

SQUEEGEE BLADES

The front squeegee blade allows solution to pass
through channels in the blade into the squeegee
assembly while maintaining vacuum to provide lift.
The front blade has four wear surfaces and can be
rotated for extended life. There are three different
notch patterns and three different colors of
squeegees for varying floor conditions. The red
blade has the most notches and is for normal,
smooth surfaces. The blue blade has less notches
and is for rougher or tiled surfaces. The green blade
has no notches and is for rough surfaces such as
knobby tile or uneven tile. The linatex blades are
used for industrial settings. The front blade should
not require regular replacement under normal use.

The rear blade wipes the floor to a near dry
condition. It is important the rear blade be in good
condition to properly do its job. As with the front
blades there are 4 rear blade options ; red, blue,
green and linatex. Front and rear blades should be
color matched. Each squeegee blade assembly has
four wear surfaces for extended service.

Check both the front and rear squeegee blades for
damage, wear, and adjustment each day in the pre­run check. Change the front blade if it is torn or has
an uneven edge. Change the rear blade if it is less
than 1/2 the original thickness.

ADJUSTING SQUEEGEE

Adjusting the squeegee is a two-part process. First,
the squeegee assembly must have correct pitch in
order for the squeegee blade to have the same
deflection at each tip as well as the center. The
knob on the squeegee linkage controls the pitch
adjustment. The second adjustment is the
deflection. Knobs on each end of the squeegee
control the Standard Squeegee Assembly
adjustment. A color-coded slide bar controls the
Smart Squeegee Option adjustment according to the
type of floor and squeegee blade employed.
