Features<br />
This battery charger contains a temperature sensitive switch that<br />
automatically shuts the charger off in the event of overload or<br />
excessive high temperature. The unit will switch back on after a<br />
cooling period.<br />
This charger IS NOT suitable for continuous charging or<br />
trickle charging.<br />
Incorrect polarity or short circuit will cause the ammeter needle to<br />
swing back and forth. Immediately disconnect the charger from the<br />
mains supply and remove terminal clamps.<br />

Monitor charging procedure<br />
Operation for Charging (NOT AUTOMATIC)<br />
1. Disconnect the battery according to the Manufacturers instruction.<br />
2. Check the levels of electrolyte and top up if necessary (This must<br />
cover the plates in the individual cells).<br />
3. Make sure battery charged is NOT plugged into mains socket.<br />
4. Connect the red clamp to the positive terminal (+) of the battery<br />
and then the black clamp to the negative terminal (-) (If charging<br />
battery that is still connected to the vehicle make sure the first<br />
charging cable IS NOT connected to the vehicle chassis.<br />
Make the next connection to the chassis at a location away from<br />
the battery and fuel line)<br />
5. Connect the charger to the power socket, turn the charger ON<br />
and check the needle on the ammeter.<br />
6. Charging current is displayed on the ammeter.<br />
(Note: There may be no indication if the battery is fully charged)<br />
7. The needle will fluctuate during charging until it reaches a<br />
constant value in the black section (though this may not reach<br />
the far left hand mark).<br />
8. Once charging is complete, switch off the unit and remove the<br />
power plug from the mains.<br />
9. Remove the terminal clamps from the battery (if in situ on the<br />
vehicle remove the connection on the chassis first).<br />
10. Re-tighten battery cell plugs.<br />
