MAINTENANCE
SERVICE PROCEDURE
EVERY 250 HOURS SERVICE
Maintenance for every 50 and 100 hours service should be carried out at the same time.
CHECK BATTERY ELECTROLYTE LEVEL
Carry out this check before operating the machine.
Do
not
use
the
battery
if
the
battery
electrolyte
level
is
below
the
LOWER
LEVEL
line.
This
will
accelerate
deterioration
of
the
inside
of
the
battery
and
reduce
the
service
life
of
the
battery.
In
addition,
it
may
also
cause
an
explosion.
The
battery
generates
flammable
gas
and
there
is
danger
of
explosion,
so
do
not
bring
fire
or
sparks
near
the
battery.
Battery
electrolyte
is
dangerous.
If
it
gets
in
your
eyes
or
on
your
skin,
wash
it
off
with
a
large
amount
of
water
and
consult
a
doctor.
When
adding
distilled
water
to
the
battery,
do
not
allow
the
battery
electrolyte
to
go
above
the
UPPER
LEVEL
line.
If
the
electrolyte
level
is
too
high,
it
may
leak
and
cause
damage
to
the
paint
surface
or
corrode
other
parts.
NOTICE
When
adding
distilled
water
in
cold
weather,
add
it
before
starting
operations
in
the
morning
to
prevent
the
electrolyte
from
freezing.
Inspect the battery electrolyte level at least once a month and follow the basic safety procedures given below.
WHEN 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 cover of the battery box.
There are two battery boxes: One on each side at the rear of the machine.
2.
Use a wet cloth to clean the area around the electrolyte level
lines and check that the electrolyte level is between the
UPPER LEVEL (U.L.) and LOWER LEVEL (L.L.) lines.
If the battery is wiped with a dry cloth, static electricity may
cause a fire or explosion.
3. If the electrolyte level is below the midway point between the
U.L. and L.L. lines, remove cap (1) and add distilled water to
the U.L. line.
4. If distilled water has been added to any cell of cap (1), add
distilled water also to the other cells.
5.
Clean the vents of the battery caps, then close the caps
securely.
Keep the top of the battery clean and wipe it with a wet cloth.
REMARK
If distilled water is added to above the U.L. line, use a syringe to lower the level to the U.L. line. Neutralize the
removed fluid with baking soda (sodium bicarbonate), then flush it away with a large amount of water or consult your
Komatsu distributor or battery maker.
