7. 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 (–) pole of the
battery before working on the electric device.
– Do not confuse the positive (+) and
negative (–) terminals of the battery.
– When fitting the battery, first connect up the
positive lead, then the negative lead.
Negative terminal to earth = engine block.
– When removing, first disconnect the negative
lead, then the positive lead.
– Always take care to avoid short-circuits and
earth (ground) contact of live cables.
– If malfunctions occur, first of all check that
cable connections make good contact.
– Replace a failed indicator light without delay.
– Do not remove the ignition key while the en-
gine is running.
– Do not disconnect the battery while the en-
gine is running. Electric voltage peaks can
cause damage to electrical components.
– In case of an emergency start in manual
mode, leave the battery (which might be dis-
charged) connected to the engine.
– For emergency operation without battery,
make sure that the plug-and-socket connector
to the instrument box is disconnected addi-
tionally before the engine is started.
– Do not splash electrical device with water jet
or pressure jet during engine cleaning.
– When carrying out welding work on the en-
gine or equipment, fit the earth clip of the
welding equipment as close to the welding
point as possible and disconnect the battery.
The connecting plug for the voltage regulator
must be removed.
The relevant circuit diagrams are enclosed with
the engine if it is equipped with an electrical
system. Additional circuit diagrams can be
supplied to order.
HATZ assumes no liability for electrical systems

8. Storage out of use
The new engine can normally be stored dry for
up to one year.
In very humid climates or coastal regions, the
protective treatment is sufficient for up to about
6 months.
For longer periods of storage, please contact
your nearest HATZ service station.
