8. Work on the electrical system
Batteries generate explosive gases.
Keep them away from naked flame and
sparks which could cause them to ignite.
Do not smoke.
Protect eyes, skin and cloth against the corro-
sive battery acid. Pour clear water over acid
splashes immediately. In case of emergency
call doctor.
Do not place any tools on top of the battery.
Always disconnect the negative (–) terminal
of the battery before working on the electrical
system.
– The
positive (+)
and
negative (–)
battery ter-
minals must not be accidentally interchanged.
– When
installing the battery
, connect the
posi-
tive lead
first, followed by the
negative lead.
Negative pole to earth (ground) on engine
block.
– When
removing the battery
, disconnect the
negative lead
first, followed by the
positive
lead
.
– In all circumstances,
avoid short circuits
and
shorts to earth (ground) at live cables.
– If electrical faults occur, first
check
for good
contact at the
cable connections.
– Replace a failed indicator light without delay.
– Do not take the key out while the engine is
running.
–
Never disconnect the battery
while the engine
is running. Electric voltage peaks can cause
damage to electronic components.
– Do not splash electrical system with water jet
or pressure jet during engine cleaning.
– When carrying out
welding work
on the en-
gine or attached equipment, attach the earth
(ground) clip as near as possible to the weld-
ing point, and disconnect the battery.
If an alternator is fitted, separate the plug con-
nector leading to the voltage regulator.
The relevant circuit diagrams are supplied with
engines which have an electrical system.
Additional copies of circuit diagrams can be ob-
tained on request.
HATZ assumes no liability for electrical systems
which have not been carried out acc. to HATZ
circuit diagrams.
9. Protective treatment
A new engine can normally be stored for up to
12 months in a dry place.
If atmospheric humidity is high (or if exposed
to sea air), protection is sufficient for about 6
months’ storage.
If the engine is to be stored for a longer period,
or laid up out of use, please consult the nearest
HATZ service point
.
