Check / Clean Radiator and Oil Cooler
Fins
WARNING! The dusts fly in all directions when
the compressed air is used. Always wear
goggles and mask.
CAUTION:
• To prevent damage on the fins during the
use of the compressed air, keep the
pressure of the compressed air to 0.20 -0.29
MPa (2 – 3 kg/cm
2
) and apply it away from
the fins.
Damage on the fins will cause water leakage
or overheating.
• At the dusty site, check the fins every day
and clean as needed.
1. Stop the machine at levelled location.
2. See "OUTRIGGER SETTING" on page 4-36
and rotate the outriggers outward.
3. See "Removing Machinery Cover" on page
5-18 and remove the machinery cover.
4. Apply the compressed air (0.20 to 0.29 MPa
{2 to 3 kg/cm
2
}) to the oil cooler (3) and
radiator (4) to remove the mud and dusts
clogged in the fins.

5. See "Installing Machinery Cover" on page
5-18 and install the machinery cover.
6. See "OUTRIGGER STOWING" on page 4-45
and rotate the outriggers inward to stow
them.
Check Battery Charge Level
WARNING!
• The electrolyte generates combustible gas
and presents explosion hazard. Do not bring
any fire close to the electrolyte.
• The electrolyte is a hazardous substance.
Avoid contact with eyes or skin. Should it
come into the contact with eyes or skin,
wash the affected area with plenty of water
and consult a physician.
Check the status by the colour displayed on the
meter on the top of the battery.
Fig. 5-48
The meter indications are as follows:
Green: Normal, with no problems.
Black: Charge is low. Recharge the battery.
White: Inspect the exterior.
NOTICE:
If the meter indication remains black even after
the battery has been recharged, the battery may
be at the end of its life cycle and therefore should
be replaced.
If the meter indication is white, check that the
casing is not damaged and there is no fluid
leakage. Replace if it is damaged.
Even if no exterior damage is visible, it may be
damaged internally or it may be at the end of its
life cycle and therefore should be replaced.
