WARNING
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.
The battery generates flammable gas and there is a danger of explosion. Do not bring any open flame
near the battery.
Battery electrolyte is dangerous object.
If it gets in your eyes or on your skin, wash it off with a large amount of water and consult a doctor.
Do not use a dry wipe to clean the battery. A wet wipe will prevent fire or explosion from static electrici-
ty.
NOTICE
Do not add the electrolyte to the battery exceeding UPPER LEVEL line.
If the electrolyte level is too high, it may leak and cause damage to the paint surface or corrode other
parts.
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.
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.
The battery box is on the front of the machine.
1.
Open the cover (1) of the battery box.
Open the cover (1) of the battery box fully, and it is se-
cured by rod (2).
2.
Clean around the electrolyte level line with a cloth wet with
water.
3.
Check that the electrolyte level is between UPPER LEVEL
line and LOWER LEVEL line.
4.
If the electrolyte level is below the middle between UPPER
LEVEL and LOWER LEVEL lines, immediately remove the
cap (3) and add the purified water (such as a commercial
battery fluid) to UPPER LEVEL line.
5.
When you add the battery fluid to the cell of cap (3), add it
to other cells as well.
6.
Clean the vent hole of the battery cap, then tighten the cap
securely.
Keep the battery top surface clean and wipe off dirt on it by using a wet cloth.
REMARK
If purified water is added to above UPPER LEVEL line, use a syringe to lower the level to UPPER LEVEL
line. Neutralize the removed fluid with baking soda (sodium bicarbonate), then flush it away with a large
amount of water. If necessary, consult your Komatsu distributor or a battery manufacturer.
7.
Release the lock of battery box cover (1), and close the cover.
METHOD FOR CHECKING ELECTROLYTE LEVEL WHEN IT IS IMPOSSIBLE TO
CHECK FROM SIDE OF BATTERY
If it is impossible to check the electrolyte level from the side of the battery, or there is no UPPER LEVEL line on
the side of the battery, check the level according to the following procedure.
