MAINTENANCE
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 the battery is wiped with a dry cloth, static electricity may cause a fire or explosion.
If it is possible to check the electrolyte level from the side of the battery, check as follows.
The battery box is on the rear left of the machine.
1.
Open cover (1) of the battery box from the platform, and fix
it with the bar.
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
cap (2) and add purified water (e.g. commercially available
replenishment water for a battery) to UPPER LEVEL line.
5.
When you add the purified water to the cell of cap (2), add
it to other cells as well.
6.
Clean the vent hole of the battery cap, then close the cap
securely.
Keep the battery top surface clean and wipe off dirt on it
using a wet cloth.
REMARK
If purified water is added to above the UPPER LEVEL line,
use a syringe to lower the level to the UPPER LEVEL line.
Neutralize the removed fluid with baking soda (sodium bi-
carbonate), then flush it away with a large amount of wa-
ter. If necessary, consult your Komatsu distributor or a bat-
tery 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 according to the following procedures.
The battery box is on the rear left of the machine.
