[10] CHECKING/REFILLING BATTERY ELECTROLYTE LEVEL
• The electrolyte generates combustible gas and presents explosion hazard. Do not bring any
fire close to the electrolyte.
• The electrolyte is a hazardous substance. Avoid contact with eyes or skin. Should it come into
the contact with eyes or skin, wash the affected area with plenty of water and consult a
physician.
• Do not refill with the electrolyte above the “Maximum level line”.
The fluid leakage can cause fire.
CAUTION
• Wipe the top of the battery with moistened cloth to keep it clean.
• Distilled water should be refilled before starting the work next day to avoid freezing.
[LEVEL CHECK]
1. Stop the machine at leveled location.
2. See “Operation 2.14 Outrigger Setting Operation” to rotate the
rotary of the “outrigger (1)” and “outrigger (2)” outward.
3. Verify the electrolyte you can see through the side of the battery
case from the side of the battery case.
NOTES
Wipe the battery case clean if it is dirty.
4. Verify that the surface of the electrolyte is at the upper level line
(1).
[REFILLING WITH ELECTROLYTE]
If the surface of the electrolyte is not at the maximum level line (1),
refill with the distilled water using the following procedure.
1. Remove the four mounting bolts (4) and remove the battery
cover (3).
2. Remove all the six battery caps (5) and refill with the distilled
water to the maximum level line (1).
NOTES
Pour diluted sulfuric acid if you spilled the electrolyte.
3. Check the ventilation hole (5) of the battery caps. Clean the cap
if clogged, and securely tighten the caps.
4. Replace the battery cover (3) to the original position after refilling
with the electrolyte, and securely tighten the four mounting bolts
(4).
5. After refilling with the electrolyte, see “Operation 2.24 Outrigger
Stowing Operation” and rotate the rotary of the “outrigger (1)”
and “outrigger (2)” inward and stow.
