METHOD FOR CHECKING BATTERY ELECTROLYTE LEVEL

• Do not use the battery if the battery electrolyte level is below LOWER LEVEL line. If you do so, it will
reduce the service life of the battery. In addition, it may cause an explosion.
• Since the battery produces combustible gas, it can explode. Do not bring any open flame close.
• Battery electrolyte is dangerous object. Also, take care that it does not stick your eye or skin. If bat-
tery electrolyte sticks to your skin, wash it away with large amounts of water, then get medical at-
tention.
• Do not add the electrolyte to the battery exceeding UPPER LEVEL line. It may leak and cause dam-
age to the paint surface or corrode other parts.
• Do not use a dry wipe to clean the battery. A wet wipe will prevent fire or explosion from static elec-
tricity.
NOTICE
If there is a fear that the battery water may freeze after refilling with purified water (such as a commer-
cial battery fluid), do the replenishment before the day's work on the next day.
Perform this procedure before operating the machine.
Inspect the battery electrolyte level at least once a month.
METHOD FOR CHECKING ELECTROLYTE LEVEL FROM SIDE OF BATTERY
If it is possible to check the electrolyte level from the side of the battery, check as follows.
1.
Open the hydraulic tank inspection cover on the left side of the machine.
2.
Clean around the electrolyte level line with a cloth wet with water.
