1.1. ELECTRICAL SAFETY
WARNING! It is the user’s responsibility to check the following:
Check all electrical equipment and appliances to ensure that they are safe before using. Inspect power supply leads, plugs and
all electrical connections for wear and damage. Sealey recommend that an RCD (Residual Current Device) is used with all electrical
products. You may obtain an RCD by contacting your local Sealey dealer.
If the charger is used in the course of business duties, it must be maintained in a safe condition and routinely PAT (Portable
Appliance Test) tested.
Electrical safety information, it is important that the following information is read and understood.
9Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.
9Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that they are secure.
9Ensure that the voltage rating on the appliance suits the power supply to be used and that the plug is tted with the correct fuse - see
fuse rating in these instructions.
8DO NOT pull or carry the appliance by the power cable.
8DO NOT pull the plug from the socket by the cable. Remove the plug from the socket by maintaining a rm grip on the plug.
8DO NOT use worn or damaged cables, plugs or connectors. Ensure that any faulty item is repaired or replaced immediately by a
qualied electrician.
This product is tted with a BS1363/A 13 Amp 3 pin plug.
If the cable or plug is damaged during use, switch the electricity supply and remove from use.
Replace a damaged plug with a BS1363/A 13 Amp 3 pin plug. If in doubt contact a qualied electrician.
Class II products are wired with live (brown) and neutral (blue) only and are marked with
The Class II symbol;
A) Connect the BROWN live wire to the live terminal ‘L’.
B) Connect the BLUE neutral wire to the neutral terminal ‘N’.
C) After wiring, check that there are no bare wires and ensure that all wires have been correctly connected.
Ensure that the cable outer sheath extends inside the cable restraint and that the restraint is tight.
8DO NOT connect either wire to the earth terminal.
Sealey recommend that repairs are carried out by a qualied electrician.
▲DANGER! BE AWARE, LEAD-ACID BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION.

1.2. PERSONAL PRECAUTIONS
9Ensure there is another person within hearing range of your voice and close enough to come to your aid, should a problem arise when
working near a lead-acid battery.
9Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.
9Have fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
9 Wash immediately with soap and water if battery acid contacts skin or clothing. If acid enters eye, flush eye immediately with cool, clean
running water for at least 15 minutes and seek immediate medical attention.
9 Remove personal metallic items such as rings, bracelets, necklaces and watches. A lead-acid battery can produce a short-circuit current
which is high enough to weld a ring or the like to metal, which would cause severe burns.
9Ensure hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine, remove ties and contain long hair.
8DO NOT smoke or allow a spark or flame in the vicinity of battery or engine.
1.3. GENERAL SAFETY INSTRUCTIONS

9 Ensure the charger is disconnected from the mains supply before attaching/detaching the power clamps to/from the battery.
9Keep tools and other items away from the engine and ensure you can see the battery and working parts of engine clearly.
9Ensure the output of the charger is the same voltage as the battery.
9Ensure that during charging, the charger is placed in a location where there is sufficient ventilation to prevent the build up of explosive
gases from a lead acid battery.
9If battery has caps to access the battery fluid, remove the caps and check the fluid level before connecting the power clamps. If
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).
9If the charger receives a sharp knock or blow the unit must be checked by a qualified service agent before using.
9If the battery terminals are corroded or dirty clean them before attaching the power clamps.
9Keep children and unauthorised persons away from the working area.
8DO NOT dis-assemble the charger for any reason. The charger must only be checked by qualified service personnel.

8DO NOT try to start engine when charger is connected to battery.
8DO NOT try to charge battery if battery fluid is frozen.
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.
8DO NOT allow power clamps to touch each other or to make contact with any metallic part of the vehicle.
8DO NOT cross connect power leads from charger to battery. Ensure positive (+/RED) is to positive and negative (-/BLACK) is to negative.
8DO NOT pull the cables or clamps from the battery terminals.
8DO NOT use the charger outdoors, or in damp, or wet locations and DO NOT operate within the vicinity of flammable liquids or gases.
