Remove personal metallic items such as rings, bracelets, necklaces and watches. A lead-acid battery can produce a short-circuit
9
current which is high enough to weld a ring or the like to metal, which would cause severe burns.
Ensure hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine, remove ties and contain long hair.
9
DO NOT smoke or allow a spark or flame in the vicinity of battery or engine.

GENErAl SAFETY iNSTrUcTiONS
Familiarise yourself with the application and limitations of the charger as well as the potential hazards. Also refer to the vehicle
9
manufacturer's hand book. IF IN ANY DOUBT CONSULT A QUALIFIED ELECTRICIAN.
Ensure the charger is in good order and condition before use. If in any doubt do not use the unit, contact your Sealey stockist.
9
Ensure the charger is disconnected from the mains supply before attaching/detaching the power clamps to/from the battery.
9
Keep tools and other items away from the engine and ensure you can see the battery and working parts of engine clearly.
9
Ensure the output of the charger is the same voltage as the battery.
9
Ensure that during charging, the charger is placed in a location where there is sufficient ventilation to prevent the build up of explosive
9
gases from a lead acid battery.
If battery has caps to access the battery fluid, remove the caps and check the fluid level before connecting the power clamps. If
9
necessary top-up the battery with distilled water by referring to the battery manufacturer's instructions (Apply the personal
safety precautions described in part 1.2).
If the charger receives a sharp knock or blow the unit must be checked by a qualified service agent before using.
9
If the battery terminals are corroded or dirty, clean them before attaching the power clamps.
9
Keep children and unauthorised persons away from the working area.
9
DO NOT dismantle the charger for any reason. The charger must only be checked by qualified service personnel.
8
DO NOT try to charge a non-rechargeable battery.
8
DO NOT try to start engine when charger is connected to battery.
8
DO NOT try to charge battery if battery fluid is frozen.
8
WArNiNG! To prevent the risk of sparking, short circuit and possible explosion DO NOT drop metal tools in the battery area, or allow
‰
them to touch the battery terminals.
DO NOT allow power clamps to touch each other or to make contact with any metallic part of the vehicle.
8
DO NOT cross connect power leads from charger to battery. Ensure positive (+/RED) is to positive and negative (-/BLACK) is to
8
negative.
DO NOT pull the cables or clamps from the battery terminals.
8
DO NOT use the charger outdoors, or in damp, or wet locations and DO NOT operate within the vicinity of flammable liquids or gases.
8
DO NOT use charger inside vehicle or inside engine compartment.
8
DO NOT use the charger for a task for which it is not designed.
8
WArNiNG! DO NOT simultaneously charge batteries of different capacities or discharge levels.
‰
WArNiNG! If a fuse blows, ensure it is replaced with an identical fuse type and rating. Use only Sealey genuine parts.
‰
When not in use, store the charger carefully in a safe, dry, childproof location.

NOTE: This appliance can be used by children aged from 8 years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction
concerning use of the appliance in a safe way and understand the hazards involved. children shall not play with the
appliance. cleaning and user maintenance shall not be made by children without supervision.
2. iNTrODUcTiON
High frequency inverter type unit designed to both charge a battery and provide support for the battery during prolonged electronic diagnostic
checks. Charge cycle has 9 profiles designed to optimise the condition of the battery and the speed of the charge. It will recover a discharged
battery (>2V) to almost 100% of its original capacity. Designed for use with lead acid and lead calcium batteries including WET, AGM/GEL and
VRLA types on 12V and 24V systems. Temperature sensor allows accurate charging of battery, even when cold. Safety circuitry prevents sparks
or polarity reversal. Once fully charged, battery may be left connected to be automatically conditioned and maintained.

4.1.
PrEPArATiON
iMPOrTANT! It is important to prepare for charging
correctly ensuring you follow Section 1 safety regulations
carefully. Check that the capacity of the battery is compatible with the charger output.
4.1.1.
Follow any vehicle manufacturer's instructions for charging the battery. Especially instructions for charging batteries which should
not ordinarily be removed from the vehicle for this process.
4.1.2.
If the battery is removed, place in an appropriate safe area, according to Section 1, ready for charging.
iMPOrTANT! a boat battery must be removed and charged on shore.
4.2.
cONNEcTiNG THE cHArGEr TO A BATTErY iNSTAllED ON THE VEHiclE.
4.2.1.
Ensure the charger black and red crocodile clips are not short circuited at any time.
4.2.2.
Identify the polarity of the battery terminals and check that they are free of corrosion deposits. Clean if required.
4.2.3.
Identify the polarity of the battery terminal connected to the vehicle chassis (earth), normally the negative terminal.
4.2.4.
Identify the system voltage of the vehicle, 12V or 24V.
4.2.5.
Remove the battery electrolyte cover or caps, when applicable, to allow the gases produced by charging to escape.
4.2.6.
If not a sealed battery, check electrolyte levels. Add distilled water in each cell according to manufacturer's instructions or 5-10 mm
above the plates if information not available. For sealed batteries refer to manufacturer's recharging instructions.
