SCRUBBING WITH THE SABER/STRIDE II
Plan the scrubbing pattern in advance. The longest track is
around the perimeter of the area to be cleaned. For efficient
operation, the runs should be the longest possible without
turning, stopping, or raising and lowering scrub deck/
squeegee.
NOTE: In order to achieve the best possible results, the
area which is to be cleaned should be swept before scrub-
bing. Large debris, strings, wire must be removed to pre-
vent being caught in brushes or squeegee.
BEGIN SCRUBBING
1. Turn key switch to “ON” and release the brake.

MACHINE OPERATION
DOUBLE SCRUB
Floors which are heavily soiled or have thick accumulations
of floor finish may not clean sufficiently with one pass. In
these cases it will be necessary to double scrub.
To double scrub, begin scrubbing as usual, but after push-
ing number 1, press the squeegee button to turn off vac mo-
tor. Manually raise the squeegee. Make the first pass over
the surface being cleaned with the solution on, and brush-
es down and squeegee up. This allows the solution to stay
in contact with the soil while loosening the surface accumu-
lation with the brushes. Allow time for the first application
tostay incontact withfloor. Length oftime betweenthe first
and second pass depends on amount of accumulation and
the type of chemical being used. A second scrubbing with
the squeegee down and again the solution and brushes on
will further loosen soil. The additional application of solu-
tion will further assist the difficult cleaning job.
EMPTYING AND CLEANING TANKS
RECOVERY TANK
1. Park the SABER/STRIDE II next to a floor drain.
Drain hose is on left rear corner of machine.
2. Turn “OFF” the key switch and set the machine
parking brake.
3. Unhook the large drain hose from the retainer and
unscrew T-handle on plug enough to release the plug,
then lower hose in direction of the drain. Recovered
solution will come out with some force.
4. The recovery tank should then be flushed out with
clean water. Hinge solution tank open to access
recovery tank.
5. If machine is to be stored, leave solution tank hinged
open.
SOLUTION TANK
1. Drain solution tank by unhooking the small solution
drain hose from left rear of tank.
2. Loosen T-handle on plug enough to remove plug.
Allow tank to drain completely.
3. Flush tank of all chemical solution.
4. Run several gallons of clean water through system.
NOTE: Never allow solution to remain in tank. Damage to
tank, seals and valves could occur.

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 bright yellow tufts located on these tufts
are pre-trimmed 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 re-
placed.
There are five different types of brushes available to cov-
er applications from cleaning heavily soiled floors to pol-
ishing. 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 SABER/STRIDE II. Please refer to
thefollowingtoassistinselecting the proper brushorpad
for the work at hand.
UNCOATED FLOORS
Aggressive Grit is a nylon fiber impregnated with sili-
cone carbide grit. It grinds away stain, soil, and removes
surface material
Mild Grit is a less aggressive silicone carbide grit suit-
able 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
Nylon Polish is the softest brush. It will gently clean fin-
ished 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.
Whenusedwithamilddetergenttheywillprovidesurface
cleaning without removing the finish.
Blue Pads (Scrubbing) are used for heavy-duty scrub-
bing, and light stripping. The blue pads remove less fin-
ish 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 re-
move 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, or damage. The scrub brush-
es should be replaced if brush bristles are missing or if
yellow Perform Alert©indicate minimum brush length.
NOTE: For uniform scrubbing, scrub brushes must be re-
placed as a set.
REPLACING OR INSTALLING SCRUB BRUSHES
1. With the scrub deck up, turn “OFF” the machine
and set the parking brake.
FOR SAFETY: Before leaving or servicing machine;
Stop on level surface, set parking brake, turn off
machine and remove key.
2. Locate release lever on top of brush or pad driver.

SCRUB DECK SKIRT AND SQUEEGEE
The skirts and squeegee should be inspected for wear
and damage. The skirt is self adjusting. Replace skirt
when they become cracked, worn, torn or brittle.
SQUEEGEE BLADES
NOTE: See page 15 of this guide for a complete table on
squeegee options.
The front squeegee blade allows solution to pass through
channels in the blade into the squeegee tool while main-
taining 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 differ-
ent colors of squeegees for varying floor conditions. The
red squeegee is used for normal, smooth surfaces. The
blue squeegee is used for tiled surfaces. The green
squeegee is used for rough surfaces. The linatex squee-
gees 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 prop-
erly do its job. The rear squeegee blades come in an as-
sembly with three different options. Each squeegee
blade assembly has four wear surfaces for extended ser-
vice.

ADJUSTING SQUEEGEE
Adjusting the squeegee is a two part process. First, the
squeegee tool must have correct pitch in order for the
squeegee blade to have the same deflection at each tip
as well as the center.
The pitch adjustment on the SABER/STRIDE II
is facilitated by the use of a spirit level mounted on the
squeegee tool. The second adjustment is the amount of
deflection or down pressure on the squeegee. The ideal
deflectionis conveniently markedby colors onthe squee-
gee tool according to the type of floor and squeegee
blade employed.
TO ADJUST SQUEEGEE PITCH
1. Choose a smooth, level surface. Turn “ON” the key
switch, release the machine parking brake. Lower
the squeegee and drive forward at least 2 feet (60
cm).
2. With the squeegee down, stop the machine with the
brake and set the parking brakes. Do not allow the
machine to roll back.
FOR SAFETY: Before leaving or servicing machine;
Stop on level surface, set parking brake, 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 tool. This should
correspond to the bubble being in the middle position
of the spirit level.
4. To decrease the deflection of the squeegee blade at
the ends, loosen plastic knobs near the squeegee
center. To increase the deflection at the ends of the
squeegee assembly, tighten plastic knobs on trailing
arm.
5. Again check the deflection of the squeegee blades.
Repeat steps 1 through 4 until the deflection is equal
across the entire rear squeegee blade.
TO ADJUST AMOUNT OF REAR SQUEEGEE
DEFLECTION
FOR SAFETY: Before leaving or servicing machine;
Stop on level surface, set parking brake, turn off ma-
chine and remove key.
1. Choose a smooth, level surface. Lower the
squeegee and drive forward at least 2 feet.
2. With the squeegee down, stop the machine with
the brake and set the parking brakes. Do not allow
the machine to roll back.
3. Observe the amount of squeegee deflection. It
should deflect 3/8 in (9.5 mm) across the entire
width of the squeegee.
4. To adjust the squeegee deflection, loosen knob on
the squeegee slide bar.
5. Slide bar to left to increase deflection. Sliding bar to
right decreases deflection
6. Turn on the key switch, release the machine parking
brake. Raise, then lower squeegee assembly.
Drive forward at least 2 feet.
7. Repeat steps 2 through 4 until deflection of 3/8 in.
(9.5 mm) is reached.
TIRES AND WHEELS
Check for low or worn tires. Fill to proper pressure as
needed (50 psi front).
Check wheel nuts for tightness, tighten as necessary to
80 foot pounds.

BATTERIES
SABER/STRIDE II 28/34 98570 7/14/98
The batteries provide the power to operate the machine.
The standard are four 6 volt batteries rated at 250 A/h at
a 6-hour rate. The batteries require regular maintenance
to keep them operating at peak efficiency.
The machine batteries will hold their charge for long peri-
ods of time, but they can only be charged a certain num-
ber 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 con-
dition for any length of time. Never expose a discharged
battery to temperatures below freezing. Discharged bat-
teries 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 dam-
aged cables and terminals.
Checkthe electrolytelevel ineach batterycell before and
after charging the batteries. Never add acid to the batter-
ies, use 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.
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.
3. Do not add water until the battery is fully charged.
4. Wipe off the top of the batteries at least once a
week.
5. Test battery condition with a hydrometer at least
once a week.
6. Ensure that all connections are tight and all
corrosion removed.
7. Every 4 to 6 months, remove the 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.
NOTE: Do not take readings immediately after adding
water, if the water and acid are not thoroughly mixed, the
reading may not be accurate.
Check the hydrometer readings against this chart
SPECIFIC GRAVITY @80° F(27° C) BATTERY CONDITION
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 elec-
trolyte is any temperature other than 80 °F(27° C), the
reading must be temperature corrected.
To find the corrected specific gravity reading when the temper-
ature of the battery electrolyte is other than 80° F(27° C):
Add(+) to the specific gravity reading 0.004(4 points), for each
10 F(6° C) above 80 F(27° C).
Subtract(-) from the specific reading 0.004(4 points), for each
10° F(6° C) below 80° F(27° C).

charging, add just enough water to cover the plates.
After charging is complete, add just enough water to
bring up the level to the indicator ring. If the water level
is too high before charging, normal expansion of the
electrolyte may cause an overflow, resulting in loss of
battery acid balance and damage to the machine.
5. Replace the battery caps, and leave them in place
while charging.
6. Unplug the battery connector from the machine.
FOR SAFETY: When charging, connect the charger to
the batteries before connecting the charger to the AC
wall outlet. Never connect the charger to the AC wall
outlet first. Hazardous sparks may result.
7. Plug the charger connector into the battery connector.
Connect the charger AC plug to a wall outlet. The
charger gauge should indicate that the batteries are
charging.
8. When the batteries are fully charged, disconnect the
charger from the AC wall outlet, then disconnect the
charger from the batteries.
9. Connect the batteries to the machine connector.
10. Check the electrolyte level. It should be up to the indi-
cator ring. If necessary add distilled water.
11. Lower the solution tank.
