MAINTENANCE PROCEDURE
Open the cover (1) at the right front of the machine and you
find the battery. The battery is installed at (A) part.
Inspect the battery electrolyte level at least once a month ac-
cording to the following procedure.
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.
Use a cloth wet with water to clean the area around the
electrolyte level lines and check that the electrolyte level is
between UPPER LEVEL (U.L.) and LOWER LEVEL (L.L.)
lines.
2.
If the electrolyte level is below the middle between UPPER
LEVEL (U.L.) and LOWER LEVEL (L.L.) lines, immediately
remove the cap (4) and add the purified water (such as a
commercial battery fluid) to U.L. line.
3.
After adding the purified water, tighten the cap (4) securely.
REMARK
If the purified water is added to above UPPER LEVEL (U.L.) line, remove the fluid by using a syringe to lower
the level to UPPER LEVEL (U.L.) line. Neutralize the removed electrolyte with baking soda (sodium bicarbon-
ate), then flush it away with a large amount of water. If necessary, consult your Komatsu distributor or a battery
manufacturer.
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 as follows.
1.
Remove the cap (4) at the top of the battery and check the
electrolyte level through electrolyte filler port (5).
