EVERY 250 HOURS OF OPERATION (Monthly)
Open the left door of the engine compartment.
Pull out the battery that is located on the floor behind
the coolers.
Use safety goggles. The battery contains
acid. Rinse with water if electrolyte comes
into contact with the body.
Never use an open flame when checking
the electrolyte level. Explosive gas is genera-
ted when the alternator is charging.
Take off the cell caps and make sure that electrolyte is
about 10 mm (0.4 in) above the plates. Check the level
of all cells. Top off with distilled water to the right level if
the level is low. The engine should be run for a while
before topping off with distilled water if the ambient
temperature is below freezing. Otherwise, the electrolyte
might freeze.
Make sure that 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.
When disconnecting the battery, always
disconnect the negative cable first. When
connecting the battery, always connect the
positive cable first.
Discard used batteries properly. Batteries
contain lead, which is detrimental to the
environment.
Before doing any electric welding on the
machine, disconnect the battery ground
cable and then all electrical connections to
the alternator.
