CIRCUIT BREAKERS / FUSES
The machine is equipped with two resettable circuit
breakers and two fuses to protect the machine from
damage. If a breaker should trip, determine the cause,
allow the motor to cool then reset the circuit breaker
button.
The circuit breakers and the fuses are located inside
the battery compartment near the hour meter (Figure
30). When replacing a blown fuse never substitute a
higher amp rated fuse than specified.

CHARGING BATTERIES
ATTENTION: To prolong the life of the batteries
only recharge the batteries if the machine was
used for a total of 30 minutes or more. Do not leave
batteries discharged for lengthy periods.
WARNING: Fire Or Explosion Hazard.
Batteries Emit Hydrogen Gas. Keep Sparks And
Open Flame Away. Keep Battery Compartment
Open When Charging.
FOR SAFETY: When servicing batteries, wear
protective gloves and eye protection when
handling batteries and battery cables. Avoid
contact with battery acid.
BATTERY CHARGER SPECIFICATIONS
SCHARGER TYPE:
-- FOR WET (Lead acid) BATTERIES
SOUTPUT VOLTAGE - 24 VOLTS
SOUTPUT CURRENT - 30 AMPS
SAUTOMATIC SHUTOFF CIRCUIT
SFOR DEEP CYCLE BATTERY CHARGING
1. Park the machine on a flat, dry surface and turn the
key off. Make sure the area is well ventilated.
2. Tilt the seat forward for ventilation (Figure 39). Use
the seat stand to hold the seat up.
FIG. 39
3. Check the battery fluid level before charging (Figure
40). The fluid level should slightly cover the battery
plates. Add distilled water if low. DO NOT
OVERFILL. The fluid will expand and may overflow
when charging.
FOR SAFETY: When servicing batteries, wear
protective gloves and eye protection when
handling batteries and battery cables. Avoid
contact with battery acid.

BATTERY MAINTENANCE
WARNING: Fire Or Explosion Hazard.
Batteries Emit Hydrogen Gas. Keep Sparks And
Open Flame Away. Keep Battery Compartment
Open When Charging.
FOR SAFETY: When servicing batteries, wear
protective gloves and eye protection. Avoid
contact with battery acid.
To prolong the life of the batteries only recharge the
batteries if the machine is used for a total of 30 minutes
or more. Never leave batteries discharged for lengthy
periods.
1. Check battery fluid levels before and after
charging. The fluid should be at the level shown
(Figure 62). Add distilled water if low. DO NOT
OVERFILL. The fluid will expand and may overflow
when charging.
Before Charging After Charging
CORRECT BATTERY FLUID LEVEL:
Fluid level slightly
above battery plates
Fluid level slightly
below sight tubes
FIG. 62
12
R14 1032129 REV.01 (12-06)
2. Clean the batteries and terminals to prevent battery
corrosion. Use a scrub brush with a mixture of
baking soda and water (Figure 63).
ATTENTION: Do not allow the baking soda solution
to enter the batteries.
FIG. 63
3. Check for loose or worn battery cables. Replace if
worn.
PRIMING SOLUTION SYSTEM
To prime the machine’s solution system, operate the
ReadySpace technology for approximately one minute
(Figure 64). Once primed, the machine can be used for
restorative extraction cleaning.
If the solution system is completely dry or if you notice
center streaking when restorative extraction cleaning,
the solution system must be primed.
FIG. 64
MACHINE JACKING
Use the designated jacking locations for jacking up the
machine (Figure 65). Empty the recovery and solution
tanks before jacking. Use a jack capable of supporting
the weight of the machine. Position the machine on a
flat, level surface and block the tires before jacking.
FOR SAFETY: When servicing machine, jack
machine up at designated locations only. Use jack
or hoist that will support machine weight. Block
machine up with jack stands.
FIG. 65
PUSHING, TOWING, AND TRANSPORTING
MACHINE
PUSHING OR TOWING THE MACHINE
Before attempting to push or tow the machine, the
brake must be disengaged. To disengage the brake,
insert a small standard screwdriver between the
electronic brake lever and the hub (Figure 66).
FOR SAFETY: When brake is disengaged, do not
push or tow the machine on inclines.
FOR SAFETY: When brake is disengaged, do not
operate machine.
FIG. 66
R14 1032129 REV.01 (12-06)
13
Only push or tow the machine on a level surface. Do
not exceed 2 mph / 3.2 kph. When towing machine,
only tow it from the front by the stabilizer arms
(U--shape bars).
Immediately after pushing or towing the machine,
enable the brake. Never operate the machine with the
brake disabled.
TRANSPORTING THE MACHINE
When transporting the machine by use of trailer or
truck, carefully follow the loading and tie--down
procedures:
FOR SAFETY: When transporting machine, go
slowly on inclines and slippery surfaces.
1. Empty the solution tank and recovery tank.
2. Raise the scrub head to the up position.
3. Load the machine using a ramp that can support
the machine weight and operator. Do not operate
the machine on a ramp incline that exceeds an 11°
angle (Figure 67). A winch must be used when
ramp incline exceeds an 11°angle.
FOR SAFETY: When transporting machine, use a
ramp that can support the machine weight and
operator. Do not operate the machine on a ramp
incline that exceeds an 11°angle. Use tie--down
straps to secure machine to truck or trailer.
11°maximum ramp angle
FIG. 67
4. Once loaded, position the front of the machine up
against the front of the trailer or truck. Lower the
scrub head and turn the key off (Figure 68).
5. Place a block behind each wheel (Figure 68).
6. Secure the front and rear of the machine with
tie--down straps (Figure 68). Route the front strap
through the stabilizer arms (U--shape bars). Route
the rear strap above the rear axle at center. It may
be necessary to install tie-down brackets to the
floor of your trailer or truck.
FIG. 68
NOTE: When transporting machine in freezing
temperatures see STORING MACHINE, step 5.
STORING MACHINE
1. Charge the batteries before storing. Never store
machine with discharged batteries.
2. Drain and rinse the tanks thoroughly.
3. Park the machine in a dry area with the scrub head
in the raised position.
4. Open the recovery tank cover to promote air
circulation.
5. If storing machine in freezing temperatures be
certain to drain tanks, purge pump and remove the
solution tank filter located under the machine at
rear.
ATTENTION: Do not expose machine to rain, store
indoors.
