Use soft water for coolant.
In freezing weather, add antifreeze to the coolant referring to the table below. Select the most
suitable mix ratio according the lowest temperature in the job location.
Long life coolant is used in our roller. Useful life of this antifreeze coolant is 2 years.
Use non-amine type long life coolant when changing coolant.
IMPORTANT
Use of a high consistency untifreeze coolant in summer time can cause the
engine to overheat depending upon job conditions. Use a coolant of 30%
solution in the hot season.
2.12.3 Battery
WARNING
• Batteries generate explosive gases. Do not use an open flame close to batteries.
• The battery electrolyte is corrosive. Keep the electrolyte away from your eyes and
skin. If you are affected by the electrolyte, flush with large quantities of water and
get medical help.
At low temperature, batteries are less efficient. The level of charge is lowered and batteries
will tend to freeze. Maintain batteries full charged wherever practicable, and give attention to
heat insulation at night for the next day’s operation.
Check the color of the hydrometer attached to the battery top to charge or replace the battery.
