Battery – Checking the
electrolyte level
EVERY 50 HOURS OF OPERATION (WEEKLY)
Never use an open flame when checking the
electrolyte level. Explosive gas is generated
when the alternator is charging.
Turn the knob (1).
Pull out the battery shelf.
Wipe the top of the battery dry.
Wear safety goggles. The battery contains
acid. Rinse with water if splashed with
electrolyte.
Take off the cell caps and ensure that electrolyte is
about 10 mm (0.39 in) above the plates. Check the
level of all cells. Top up with distilled water to the right
level if the level is low. If the air temperature is below
freezing point the engine should be run for a while
before topping up with distilled water. There is
otherwise a danger that the electrolyte will freeze.
Ensure that the ventilation holes in the cell cover are
not clogged. Then put the cover back on.
The cable shoes should be clean and well tightened.
Clean corroded cable shoes and grease them with
acid-free Vaseline.
Ensure always that the battery box is
closed and locked while driving.
When disconnecting the battery, always
disconnect the negative cable first. When
connecting the battery, always connect the
positive cable first.
Get rid of discarded batteries in a proper way.
Batteries contains lead which is detrimental to
the environment.
Before doing any electric welding on the
machine, disconnect the battery earth
cable and then all electrical connections to
the alternator.
