Nobles Speed Scrub 500 (01-2017)

FOR SAFETY: The use of incompatible battery
chargers may damage battery packs and
potentially cause a fire hazard.

IMPORTANT NOTICE:

The battery charger is set to

charge the battery type supplied with your machine. If
you choose to change to a different battery type or
capacity (i.e. flooded (wet) lead-acid,
maintenance-free, sealed, AGM batteries, etc.), the
charger's charging profile must be changed to prevent
battery damage. See BATTERY CHARGER
SETTINGS.

1.

Transport the machine to a well-ventilated area.

WARNING: Batteries emit hydrogen gas.

Explosion or fire can result. Keep sparks and open
flame away when charging.

2.

Park the machine on a flat, dry surface, turn off
machine and remove key.

FOR SAFETY: When servicing batteries, stop on
level surface, turn off machine, remove key and set
parking brake if equipped.

3.

If the machine is equipped with flooded (wet) lead-
acid batteries check the battery electrolyte level
weekly before charging. For models equipped with
the automatic battery watering system, check if the
automatic battery water tank needs refilling. Add
distilled water if low.

4.

For models equipped with an on-board charger,
remove the charger's power cord from the storage
hooks and plug power cord into a properly
grounded wall outlet (Figure 72).

FIG. 72

For models equipped with off-board chargers, first
connect the charger's DC cord into the machine's
battery charge receptacle then plug the AC power
supply cord into a properly grounded wall outlet
(Figure 73). Refer to the off-board battery charger's
owner manual for operating instructions.

FOR SAFETY: Do not disconnect the off-board
charger's DC cord from the machine's receptacle
when the charger is operating. Arcing may result. If
the charger must be interrupted during charging,
disconnect the AC power supply cord first.

FIG. 73

5.

The charger will automatically begin charging and
and shut off when fully charged. The maximum
charging cycle may take up to 6-12 hours
depending on battery type.
On-board battery charger: The battery discharge
indicator lights will ripple back and forth during the
charging cycle. When all five lights repeatedly flash
two times, the charging cycle is complete (Figure
74).

FIG. 74

ATTENTION: Do not disconnect battery cables
while charger is plugged in, circuit board damage
may result.

6.

After charging batteries unplug the power supply
cord and wrap cord around the cord hooks (Figure
75).
For models equipped with an off-board charger,
always disconnect the AC power supply cord first
before disconnecting charger from machine (Figure
75).
