How To Prepare the Machine For Operation
Battery Maintenance
The electrical power to operate the machine comes from the storage batteries.
Storage batteries need preventative maintenance.
WARNING: Working with batteries can be dangerous. Always
wear eye protection and protective clothing when
working near batteries. NO SMOKING!
To maintain the batteries in good condition, follow these instructions:
1. Keep the electrolyte at the correct level. The correct level is between
1/4” (1/2 cm) below the bottom of the tube in each cell and above the
tops of the plates. Check the level of the electrolyte each time you
charge the batteries (see figure 4).
NOTE: Check the level of electrolyte prior to charging the batteries. Be sure
the plates in each cell are covered with electrolyte before charging. Do
not top off the cells prior to charging the battery. Electrolyte expands
during charging. As a result, the electrolyte could overflow from the
cells. Always top off the cells with distilled water after charging.
CAUTION: Irreversible damage will occur to the batteries if
electrolyte does not cover the plates. Keep the
electrolyte at the correct level.
CAUTION: Machine damage and discharge across the tops
of the batteries can occur if the batteries are over
filled. Do not fill the batteries up to the bottom
of the tube in each cell. Wipe any acid from the
machine or the tops of the batteries. Never add
acid to a battery after installation.
CAUTION: Batteries must be refilled with distilled water only.
Do not use tap water as it may contain contami-
nants that will damage batteries.
2. Keep the tops of the batteries clean and dry. Keep the terminals and
connectors clean. To clean the top of the batteries, use a damp cloth
with a weak solution of ammonia or bicarbonate of soda solution. To
clean the terminals and connectors, use a terminal and connector clean-
ing tool. Do not allow ammonia or bicarbonate of soda to get into the
batteries.
3. Keep the batteries charged.

How to Charge the Batteries
WARNING: Charging the batteries in an area without ad-
equate ventilation could result in an explosion.
To prevent an explosion, charge the batteries
only in an area with good ventilation.
WARNING: Lead acid batteries generate gases which could
explode. Keep sparks and flames away from
batteries. NO SMOKING!
CAUTION: See Charger Owner’s Manual. All onboard
battery chargers are programmed for a specific
type battery. The charger may need reprogram-
ming to properly charge replacement batteries
different than the originally equipped Clarke
battery.
NOTE: Only replace batteries with the identical Clarke battery pack as
originally equipped. The correct Clarke battery part number can be
found on the Clarke battery label affixed to the top of each battery.
If the replacement battery is a different Clarke battery, please con-
tact Clarke Technical Service, 1-800-356-7274, for instructions.
If the replacement battery is not a Clarke battery, please contact the
charger manufacturer for instructions.
To charge the batteries, follow this procedure:
1. Make sure the key switch is in the “OFF” position.
2. Raise the seat base support.
3. Connect the battery charger AC cord to a 15 amp (min) 120V properly
grounded wall receptacle.
4. Observe indicator light to ensure the charging process has started
(see figure 5, A - Red, B - Yellow, and C - Green ). For color indica-
tions see figure 6.
Recharging the Batteries
The Focus Rider Scrubber comes with an on board charger.
1. Plug into any wall socket and charging is automatic.
2. Observe indicator light to ensure the charging process has started
(see figure 5, A - Red, B - Yellow, and C - Green ). For color indica-
tions see figure 6.
NOTE: Make sure you plug into a circuit that is not loaded by other equip-
ment. Wall breakers may be tripped and no charge will occur.
WARNING: Never charge a GEL battery with an unsuitable
battery charger. Carefully follow the instruc-
tions given by the manufacturer of the batteries
and battery charger.
NOTE: To prevent permanent damage to the batteries, avoid their complete
discharge. Never leave the batteries completely discharged, even if the
machine is not being used. When recharging the batteries, keep the base
support of the seat lifted. After every 20 recharging operations, check the
level of the electrolyte and if necessary top off with distilled water.
