Battery - Komatsu WB93S-5 F50003 Operation & Maintenance Manual

3.10.3 BATTERY

To avoid explosions due to the presence of gas, do not provoke sparks and do not use naked flames
q
near the battery.
The battery electrolyte is dangerous. If it comes in contact with the eyes or the skin, immediately rinse
q
with plenty of water and consult a doctor without delay.
To prevent the fluid from freezing, add distilled water in the morning, before starting work.
q
1 - When the ambient temperature decreases, the battery capacity decreases accordingly and, if the battery
charge is low, the electrolyte may freeze.
Keep the battery completely charged and insulate it to protect it from low temperatures, so that the machine
can be started without problems the following day.
2 - Measure the specific weight of the fluid and check the battery charge percentage, making reference to the
following table:
CHARGE PERCENTAGE
100%
90%
80%
75%
3.10.4 OTHER PRECAUTIONS
1 - Before using the machine in normal operating conditions, carry out some slow forward and reverse
movements, and operate all the bucket and backhoe cylinders slowly more than once.
These operations serve to warm up and fluidize the oil in the hydraulic circuit, the transmission, the axles and
the brakes.
3.10.5 PRECAUTIONS TO BE TAKEN AT THE END OF WORK
1 - Remove mud and water completely from the machine body.
Park the machine on firm ground; if the machine must be parked near banks or ditches, park it on wooden
boards in order to distribute the weight of the machine on a larger surface.
2 - Be careful to water drops forming on the hydraulic cylinder rods: these drops must be completely removed,
since if they freeze the cylinder gaskets may be damaged.
After removing the water drops, protect the rods with oil.
3 - Drain the condensate that may have formed in the tank and in the water separator, to prevent the water from
freezing during the night.
4 - Since the battery capacity may decrease considerably at low temperatures, after work cover the battery or
remove it and store it at a suitable temperature.
