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.

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).

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.
SQUEEGEE DEFLECTION
CORRECT
TO REMOVE SQUEEGEE ASSEMBLY
1. With the squeegee in the up position, turn key
switch “OFF”.
2. Disconnect vacuum hose from squeegee and loosen both knobs.
3. Pull squeegee assembly rearward from the lifting carrier.
4. Inspect or repair as necessary and reinstall.
TO REPLACE OR ROTATE REAR SQUEEGEE BLADES
1. With the squeegee in the up position, turn key
switch “OFF”.
FOR SAFETY: Before leaving or servicing machine; stop on level surface, turn off machine and remove key.
2. Remove the squeegee assembly from the machine. Unlatch and remove blade retainer strap and remove squeegee blade.
3. Rotate the squeegee to new edge position or replace as required. Each blade has four new edge positions.
4. Install blade on locating pins of squeegee assembly.
5. Install squeegee retainer strap.
6. For Smart Squeegee Option Only: Fasten and
lock latch, adjust latch only tight enough to take up slack in retaining strap.
TO REPLACE OR ROTATE FRONT SQUEEGEE BLADE – STANDARD SQUEEGEE ASSEMBLY ONLY
1. With the squeegee in the up position, turn key
switch “OFF”.
2. Remove the squeegee from the machine. Loosen three thumbscrews and remove the retainer strap and squeegee blade.
3. Rotate the squeegee to new edge position or replace as required. Each blade has four new edge positions. When installing the front blade, tighten the center thumbscrew first. Insure that the retainer strap is pressed against the blade before tightening the outer screws.

TO ADJUST SQUEEGEE PITCH
1. Choose a smooth, level surface. Turn “ON” the
key switch. Lower the squeegee and drive forward at least 2 feet (60cm.).
2. With the squeegee down, stop the machine. Do not allow machine to roll back.
FOR SAFETY: Before leaving or servicing the machine ; stop on level surface, turn off machine and remove key.
3. Determine the differences, if any, in deflection of
the squeegee blade between each end and the middle. Proper adjustment is obtained when deflection is equal all the way across the squeegee blade.
4. To decrease the deflection of the squeegee blade at the ends, loosen plastic knob near the squeegee center. To increase the deflection at the ends of the squeegee assembly, tighten plastic knob.
5. Check the deflection of the squeegee blades again. Repeat steps 1 through 4 until the deflection is equal across the entire rear squeegee blade.
TO ADJUST AMOUNT OF REAR SQUEEGEE DEFLECTION
1. Choose a smooth, level surface. Lower the
squeegee and drive forward at least 2 feet.
2. With the squeegee down, stop the machine. Do not allow machine to roll back.
FOR SAFETY: Before leaving or servicing machine; stop on level surface, turn off machine and remove key.
3. Observe the amount of squeegee deflection. It
should deflect 3/8 in. (9.5mm) across the entire width of the squeegee.
4. To increase the squeegee deflection, turn the 2 knobs at the squeegee ends CCW. To decrease the deflection, turn the knob CW.
NOTE: The deflection should be consistent along the length of the squeegee. If the deflection varies from end to end the knobs can be adjusted independently to correct the variation.
5. Turn on the key switch. Raise, then lower squeegee assembly. Drive forward at least 2 feet.
6. Repeat steps 2 through 4 until deflection of 3/8 in. (9.5mm) is reached.
