CIRCUIT BREAKERS AND FUSES
FIG. 7

The machine is equipped with four resettable circuit
breakers and four fuses to protect the machine from
damage. If a breaker should trip, determine the cause,
allow the motor to cool then manually reset the circuit
breaker button. The circuit breaker panel is located
near the battery compartment (Figure 29). The fuses
are located inside the circuit breaker box. When
replacing a fuse never substitute a higher Amp rated
fuse than specified.

If your machine is equipped with the on--board charger,
the charger settings must be set for your battery type
before charging. Failure to properly set will result in
battery damage.
To determine your battery type, see battery label.
Contact your battery supplier if not specified.
To verify the setting of the charger, connect the charger
cord into an electrical receptacle. The charger will
display a sequence of codes. One of the codes will
either read “GEL” or “Acd” (Figure 41).
GEL = Set for sealed/maintenance free batteries
Acd = Set for wet/lead acid batteries

To change the setting, unplug the charger, peel up the
corner of the display label and set the switches
accordingly (Fig. 42). The charger cord must be
unplugged when resetting.

NOTE: The machine will not operate when charging.

USING THE ON--BOARD BATTERY CHARGER
IMPORTANT: Before charging, make sure that the
charger setting is properly set for your battery type
(See ON--BOARD CHARGER SETTINGS).
1. Transport the machine to a well--ventilated area.

6. The charger will display a sequence of codes once
the cord is connected (Figure 45).
Three--digits + the following code:
A = Charging current
U = Battery voltage
h = Charging time
C = Charging ampere--hours [Ah]
E = Energy used [Kwh]
“GEL” or “Acd” = Battery type the charger is
currently set for. Before charging make sure
your battery type matches the display:
GEL=Sealed, Acd=Wet (lead acid). To change
setting, see ON--BOARD CHARGER
SETTINGS.
Press the arrow button to review the codes.

2. Park the machine on a flat, dry surface. Turn the
key off and set the parking brake, if equipped.
3. If charging wet (lead acid) batteries check the fluid
level before charging (See BATTERY
MAINTENANCE).
4. Prop up the recovery tank for ventilation
(Figure 43).

FIG. 45

7. Once the charging cycle begins, the indicator lights
will progress from red, yellow to green. When the
green indicator light comes on, the charging cycle
is done. Unplug the charger cord.

FIG. 43

If the charger detects a problem, the charger will
display an error code (See ON--BOARD BATTERY
CHARGER ERROR CODES).

5. Connect the charger’s AC power supply cord into a
properly grounded receptacle (Figure 44).

ADJUSTING SCRUB HEAD BRUSHES

CYLINDRICAL BRUSH MODEL

To ensure optimum scrubbing performance periodically
check the scrub head for proper adjustment.

After installing a new set of cylindrical brushes check
the brush pattern to ensure proper brush adjustment.
Brushes that are not properly adjusted will result in
premature wear and poor scrubbing performance
(Figure 50).

FOR SAFETY: Before adjusting scrub head, stop
machine on level surface, remove key and set
parking brake if equipped.

1. With brushes installed, lower the scrub head and
apply medium brush pressure.
2. Turn machine off and remove key.
3. From the center front and back of scrub head,
measure the distance from the top edge of scrub
head to the floor (Figure 48).

FIG. 50

To Inspect the Brush Pattern:
1. Position the machine on a dry dusty floor or apply a
powdered substance, such as chalk.
2. Disconnect the drive motor wire connector to keep
machine from moving forward (Figure 51).

FIG. 48

4. If scrub head is not level, loosen the lock nut and
turn the scrub head leveling screw to level. Tighten
down the lock nut once head is level (Figure 49).

3. Lower the scrub head to the floor and apply
maximum brush pressure.
4. Shut off the solution flow.

6. Raise the scrub head and pull the machine away.
7. Observe the brush pattern on floor. If the brush
pattern is uneven or tapered, adjustment is
required.
8. Reconnect drive motor wire.

8. Check the machine for leaks.
BATTERY MAINTENANCE (Wet/lead acid batteries)
1. Check battery fluid level frequently to prevent
battery damage. The fluid should be at the level
shown (Figure 75). Add distilled water if low. DO
NOT OVERFILL, the fluid may expand and
overflow when charging.

SQUEEGEE BLADES
When the blades become worn, simply rotate the
blades end-for-end or top-to-bottom to a new wiping
edge. Replace blades when all edges are worn.
The front blades on the 28 in / 700 mm and 32 in /
800mm squeegee assemblies have 12/14 slots on one
edge and 6 slots on the opposite edge (Figure 77). If
making sharp turns with the cylindrical brush models
use the 12/14 slotted edge for maximum water pickup.
6 Slots on

Replacing Squeegee Blades:
1. Loosen the band clamp and remove the band from
the squeegee assembly (Figure 78).

FIG. 75

WARNING: Fire Or Explosion Hazard.
Batteries Emit Hydrogen Gas. Keep Sparks And
Open Flame Away. Keep Battery Compartment
Open When Charging.
2. Clean the batteries to prevent battery corrosion.
Use a scrub brush with a mixture of baking soda

JACKING UP MACHINE
Use the designated locations to jack up the machine for
service (Figure 84). Empty the recovery and solution
tank and position the machine on a level before jacking.
FOR SAFETY: When servicing machine, jack
machine up at designated locations only. Use jack
or hoist that will support machine weight.

FIG. 85

STORING MACHINE
1. Charge the batteries before storing machine to
prolong the life of the batteries.
2. Drain and rinse the tanks thoroughly.
FIG. 84

TRANSPORTING MACHINE
When transporting the machine by trailer or truck, be
certain to follow the transporting procedure below:
1. Drain machine tanks.
2. Load the machine using a ramp that can support
the machine weight and person loading it. The
maximum ramp incline should not exceed 11° at a
ramp length of 3.7m (12 ft).
3. Position the front of machine up against the front of
the trailer or truck. Lower the scrub head and
squeegee.
4. Set the parking brake, if equipped, and place a
block behind each wheel to prevent the machine
from rolling.

3. Store the machine in a dry area with the squeegee
and scrub head in the up position.
4. Open the recovery tank cover to promote air
circulation.
ATTENTION: Do not expose machine to rain, store
indoors.
5. If storing machine in freezing temperatures, make
sure to drain machine of all water.
For models equipped with the FaST System, follow
the FaST SYSTEM FREEZE PROTECTION
procedure below.
FaST SYSTEM FREEZE PROTECTION
Valve Coupling #1006205 and 6 in / 15 cm Hose
#63182 are required (Purchased separately).
1. Remove the FaST--PAK carton and connect the
valve coupling and 15 cm hose (purchased parts)
to the supply hose (Figure 86).

5. Secure with tie--down straps as shown (Figure 85).
It may be necessary to install tie-down brackets to
trailer or truck.
FOR SAFETY: When loading/unloading machine
onto/off truck or trailer, use a ramp that can
support the machine weight and person loading it,
do not exceed a 11° ramp incline at a ramp length
of 3.7m (12 ft), use tie--down straps to secure
machine and block machine wheels.

FIG. 86

2. Disconnect the opposite end of the supply hose
from the injector assembly and drain the supply
hose (Figure 87). To access the injector assembly
remove the front shroud.

7. To drain the anti--freeze, repeat the draining
process above and reconnect the supply hose to
the FaST--PAK carton.

RECOMMENDED STOCK ITEMS
Refer to the Parts List Manual for recommended stock
items. Stock Items are clearly identified with a bullet
preceding the parts description. See example below:

FIG. 87

3. Reconnect the supply hose to injector assembly
and pour a recreational vehicle (RV) anti--freeze
into the supply hose until full (Figure 88).

FIG. 88

4. Operate the FaST system as normal until the
foaming stops. This step could take anywhere from
5--10 minutes.
