PROCEDURE FOR NORMAL CHARGING

NOTE: All references in brackets refer to Fig. 1

1) Before charging or boosting, ensure that the cells are filled with electrolyte to the

correct level by adding distilled water where necessary.

2) Where appropriate we recommend that the non-earthed lead on the battery is

disconnected prior to charging. It is possible that damage may occur to any

electronically controlled system fitted to the vehicle such as engine management,

anti-theft alarm, alternator etc.

3) Check that the mains supply is OFF and the Current Control Knob (B) is in the ‘O’ OFF position.

4) Connect the appropriate lead to the unearthed battery terminal (on most modern

cars this is positive (+ve) terminal), then connect the other lead to the chassis (or a

suitable engine bolt) away from the battery and fuel line.

NOTE: Ensure the RED (+ve) lead is plugged into the 12V or 24V receptacle, depending

upon the voltage of the battery to be charged

5) Remove the battery filler caps, where appropriate, during charging in order to prevent

the build up of dangerous gases within the battery.

6) Switch ON the mains supply

7) Turn the Current Control Knob (B) to the position necessary to obtain the required

charge rate, as indicated on the ammeter - 3 charging rates are provided.

CAUTION: Avoid high charge rates with sealed batteries

8) Keep the battery on charge until the Ammeter (G) reads zero (or 0-2 amps) or has

stopped moving down, then turn the Current Control Knob (B) to the OFF position.

10) When disconnecting the charger, disconnect 1. supply, 2. chassis conductor

and 3. battery conductor, IN THAT ORDER.

Important:

If the fixed positive lead and the fixed negative lead are connected to the wrong

terminals, then a flash will occur when the 2nd Clamp is attached. Damage to the

charging unit and the battery will be avoided as your START’N CHARGE is fitted with

a polarity protection feature. It will however be necessary to replace the internal

fuse. Remove the black plastic cover on the front panel (marked ‘fuse’) and replace

the burnt fuse with an exact replacement. See ‘Specifications’ for replacement fuses.

CHARGING WITH TIMER

1. Follow the same instructions as for NORMAL CHARGING UP TO AND INCLUDING PARA. 6

2. Turn the timer control knob (A) clockwise to the desired charging time setting.

3. Switch ON the mains supply.

4. Turn the Current Control Knob (B) clockwise to position 5 or 6, to obtain the desired

charging rate as indicated on the ammeter.
