OPERATION
FS-2000 Battery Scrubber (10--04)
13
WEEKLY MAINTENANCE
(Every 20 Hours of Use)
1. Check fluid level in battery cells (See BATTERY
CHARGING).
2. Clean battery tops from corrosion (See BATTERY
CHARGING).
3. Check for loose or corroded battery cables.
MONTHLY MAINTENANCE
(Every 80 Hours of Use)
1. Lubricate all linkage pivot points with silicon spray
then coat with a water resistant grease to maintain
a smooth operation.
2. Check machine for water leaks and loose nuts and
bolts.
QUARTERLY MAINTENANCE
(Every 250 Hours of Use)
Inspect motors for carbon brush wear. Replace
brushes when worn to a length of 10mm (0.38 in.) or
less. Contact an Authorized Service Center for carbon
brush inspection.
ATTENTION: Contact an Authorized Service
Center for machine repairs. Machine repairs
performed by other than an authorized person will
void the warranty.
BATTERY MAINTENANCE
W ARNING: Keep Sparks And Open Flame
Away. Keep Battery Hood Open When Charging.
FOR SAFETY: When servicing machine, wear
protective gloves and safety glasses when
handling batteries and battery cables. Avoid
contact with battery acid.
1. Always follow proper charging instructions
(see CHARGING BATTERIES).
2. Check fluid level (A) in each battery cell. The fluid
level should be 1 cm (3/8 in.) from the bottom of
sight tubes after charging. Add distilled water if
needed. DO NOT OVERFILL. Overfilled batteries
can overflow during charging due to fluid
expansion (Figure 25).

3. After charging batteries, measure the specific
gravity in each battery cell using a hydrometer
(Figure 26). This will determine the charge level
and condition of the batteries. If one or more of
the battery cells test lower than the other battery
cell (0.050 or more), the cell is damaged,
shortened, or is about to fail.
NOTE: Do not take reading immediately after adding
distilled water. The water and acid must be thoroughly
mixed in order for accurate reading.
