Checking Battery Specific Gravity - Windsor Saber Compact SC20 Operating Instructions Manual

CHECKING BATTERY SPECIFIC GRAVITY

Use a hydrometer to check the battery specific
gravity.
Battery Check
CHECKING GRAVITY
A. Hydrometer
B. Battery
NOTE: Do not take readings immediately after
adding distilled water, if the water and acid are not
thoroughly mixed, the reading may not be
accurate.
Check the hydrometer readings against this chart.

NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 80°F
(27°C), the reading must be temperature
corrected.
To find the corrected specific gravity reading
when the temperature of the battery electrolyte is
other than 80°F (27°): Add (+) to the specific
gravity reading 0.004 (4 points), for each 10°F
(6°C) above 80° (27°C).
Subtract (-) from the specific reading 0.004 (4
points), for each 10°F (6°C) below 80°F (27°C).

TO CHARGE THE BATTERIES
! CAUTION
When servicing machine, avoid contact with
battery acid.
! WARNING
! WARNING
Batteries emit hydrogen gas. Explosion or fire
can result. Keep sparks and open flame away.
Keep covers open when charging.
! WARNING
Wear eye protection and protective clothing
when working with batteries.
! WARNING
Charge batteries in a well ventilated area. Leave
the solution tank open.
Use a 24 volt, 20 amp maximum output, DC charger
which will automatically shut off when the batteries
are fully charged to charge the two battery pack.
1. Stop the machine in a clean, well ventilated area
next to the charger.
2. Turn the machine power off.
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, turn off machine
and remove key.
3. Drain solution tank and raise the solution tank
and lock the support arm. Make sure the
