Master switch

IMPORTANT
The machine is provided with an alternator.
The battery master switch must therefore always remain
turned ON while the engine is running.
If it is turned OFF, or if the start switch is turned OFF while
the engine is running, the alternator may be damaged.
Battery master switch (A) is located inside of the tool box which is
located on the right side of the machine.
After finishing work for the day, the battery master switch should
be turned OFF..

WARNING!
Battery gas (hydrogen) is flammable.
Do not expose to sources of fire such as open flame,
cigarettes, or sparks.
If battery electrolyte is splashed onto clothes or skin,
immediately flush with clean water.
If battery electrolyte is splashed into the eyes, immediately
flush with large amounts of clean water and consult a
doctor.
Checking electrolyte level
1 Open the cover of the battery box on the right side of the ma-
chine.
2 Loosen cap (A)
The electrolyte level should stand approx. 10 mm (0.4 in)
above the cell plates.
If the level is too low
1 Top up with distilled water.
2 Operate the machine after toping up, so that the water is mixed
in with the battery electrolyte. This is particularly important in
cold weather.
3 Check that cable terminals and pole studs are clean, well tight
end and coated with petroleum jelly or similar.
