SAFETY PRECAUTIONS
1. To prevent the battery from overheating and consequent damage, use
the BOOST facility sparingly and do not exceed our recommendations.
2. Battery acid is highly corrosive. If spillage occurs, wipe off immediately and
wash copiously with water. Particularly avoid contact with the eyes.
3. Do not expose this unit to rain.
4. Never touch the negative and positive leads together.
5. Never attempt any electrical or mechanical repair. If you have a problem
with your machine contact your local stockist for service information.
6. Before charging ensure the battery terminals are clean, and that the cells
are filled with electrolyte to the correct level by adding distilled water
where necessary.
7. Where appropriate we recommend that the positive (+) lead to the
battery is disconnected on the vehicle prior to charging. This will prevent
damaging the vehicle electronics.
8. When charging is completed, ensure that the vehicle battery leads are
secured to the correct terminals which should be clean and lightly
smeared with petroleum jelly to prevent corrosion. Finally, re check the
electrolyte level.
WARNING: BECAUSE HIGHLY FLAMMABLE HYDROGEN GAS IS RELEASED
IN THE PROCESS OF BATTERY CHARGING, ALWAYS REMEMBER TO SWITCH
OFF FIRST TO AVOID SPARKING, WHICH CAN OCCUR WHEN
CONNECTING OR DISCONNECTING LIVE LEADS.
WARNING: CERTAIN TYPES OF SEALED OR MAINTENANCE-FREE BATTERIES
NEED EXTRA CARE WHEN CHARGING. PLEASE CONSULT BATTERY
MANUFACTURERS INSTRUCTIONS BEFORE USING THIS UNIT.
