Battery; Other Precautions; Precautions To Be Taken At The End Of Work - Komatsu SK818-5 Operation & Maintenance Manual

PRECAUTIONS TO BE TAKEN IN THE COLD SEASON

3.11.3 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.
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 fol-
lowing table:
3 - When the electrolyte level is low, add distilled water before starting work, rather than after work, in order to
prevent the fluid from freezing during the night.

3.11.4 OTHER PRECAUTIONS

1 - Before using the machine in normal operating conditions, carry out some slow movements either forward and
in reverse, and operate all the work equipment cylinders slowly more than once.
These operations serve to warm up and decrease the viscosity of the oil in the hydraulic circuit and the trans-
mission.

3.11.5 PRECAUTIONS TO BE TAKEN AT THE END OF WORK

1 - Completely remove mud and water from the machine body.
Park the machine on firm ground; if the machine must be parked near banks or ditches, park it on wooden bo-
ards 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, 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 re-
move it and store it at a suitable temperature.
