B.
....using the 12 Volt Adapter
1.
Plug the small adapter into the socket at the front of the unit, then the cigarette lighter
adapter into the receptacle on the vehicle and start the engine. The red LED will
illuminate to denote charging is in progress.
2.
Continue to charge until the voltmeter registers 'Battery Charged' when the 'TEST'
button
is pressed, WITH THE CHARGING CURRENT DISCONNECTED. i.e., disconnect
the cigarette
lighter adapter from the receptacle on the vehicle before pressing
the TEST switch.
NOTE:
We recommend that you use this system only when necessary, as prolonged use will reduce the
life expectancy of the battery, due to the fact that this method can only charge the battery to
approx. 50% of its capacity.
For maximum battery life, we strongly recommend that you maintain the battery ina fully
charged state at all times.
If charging does not take place, check the 5 Amp fuse within the cigar lighter adapter plug.
Ensure all connections are clean and free of grease etc.

MAINTENANCE

Always inspect the Jumpstart before use to ensure the cables are in good condition,
and the clamps are clean and free from corrosion. Have them replaced if any damage
is apparent.
Keep clean by wiping with a dry cloth. DO NOT use solvents as a cleaning agent.

1. Replacing the Battery

1.
Unscrew and remove the 10 self tapping screws securing the back cover. Lift off the
cover to expose the battery and other components. Take care when setting aside
the
cover, not to damage the attached electric cables
2.
Lift out the battery from the battery compartment, and detach the cables, from the
battery terminals. It will be necessary to cut the sheaths from the terminals to gain
access to the securing screws.
3.
Taking great care not to short across the battery terminals, connect the RED heavy
duty cable to the battery terminal painted RED, and the black cables to the other
battery terminal. Wrap insulating tape (not supplied), tightly around the terminals, once
the cables are attached.
4.
Gently slide the new battery into position in its compartment ensuring the packing
piece, stuck to the front of the battery, is in place.
Replace the back cover and secure with the 10 self tapping screws.

2. Replacing the Light Bulb

1.
Gently squeeze the sides of the lens bezel together to disengage the clips at either
side, and pull the bezel out. If this proves to be difficult, the gentle use of a screwdriver
to push in the retaining clip in the middle of the rear edge of the bezel may be required.
2.
Unscrew and remove the burned out bulb and screw in a replacement.
3.
Snap the lens and bezel back into place.
