1. SAFETY INSTRUCTIONS
THE FOLLOWING STATEMENTS ON ELECTRICAL SAFETY MUST BE READ AND UNDERSTOOD BEFORE USING THE CHARGER.
1.1. ELECTRICAL SAFETY. WARNING! It is the user’s responsibility to check the following:
You must check all electrical equipment and appliances to ensure they are safe before using. You must inspect power supply leads,
plugs and all electrical connections for wear and damage. You must ensure the risk of electric shock is minimised by the installation of
appropriate safety devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board.
We recommend that an RCD (Residual Current Device) is used with all electrical products. It is particularly important to use an RCD
with portable products that are plugged into an electrical supply not protected by an RCCB. If in doubt consult a qualified electrician.
You may obtain a Residual Current Device by contacting your Sealey dealer. You must also read and understand the following
instructions concerning electrical safety.
1.1.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by a qualified
person, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of the appliance and
the safety of the appliance operator. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. DO ensure the insulation on all cables and the product itself is safe before connecting to the mains power supply. See 1.2.1. above
and use a Portable Appliance Tester (PAT).
1.1.4. DO ensure that cables are always protected against short circuit and overload.
1.1.5. DO regularly inspect power supply, leads, plugs for wear and damage and all electrical connections to ensure that none is loose.
1.1.6. DO check that the voltage marked on the product is the same as the electrical power supply to be used and check that all fused plugs
are fitted with the correct capacity fuse.
1.1.7. DO NOT pull or carry the powered appliance by its power supply lead and do not pull plug by the cable. Products must not be pulled
or carried by their output cables.
1.1.8. DO NOT use worn or damage leads, plugs or connections. Immediately replace or repair by a qualified
electrician.
1.1.9. If an extension reel is used, it must be fully unwound before connection to an RCD protected circuit. The
cable core must be a minimum of 1.5mm².

1.1.10. Important: Ensure that the voltage marked on the appliance matches the power supply to be used and
that the plug is fitted with the correct fuse - see fuse rating below. When a BS 1363/A UK 3 pin plug is
damaged, cut the cable just above the plug and dispose of the plug safely. Fit a new plug according
to the following instructions (UK only).
a) Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.
b) Connect the BROWN live wire to the live terminal ‘L’.
c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
d) After wiring, check that there are no bare wires, that
all wires have been correctly connected, that the cable outer insulation extends
beyond the cable restraint and that the restraint is tight.
Double insulated products, which are always marked with this symbol , are fitted with
live (brown) and neutral (blue) wires only. To rewire, connect the wires as indicated in diagram.
DO NOT connect either wire to the earth terminal.

1.3. PERSONAL PRECAUTIONS
Ensure there is another person within hearing range of your voice, or close enough
to come to your aid, should a problem arise when working near a lead-acid battery.
Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.
Have fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
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.
Remove personal metallic items such as rings, bracelets, necklaces and watches.
Ensure hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine, remove ties and contain long hair.
DO NOT smoke or allow a spark or flame in the vicinity of battery or engine.
DANGER! BE AWARE, LEAD-ACID BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON,
IT IS VERY IMPORTANT TO READ AND FOLLOW THESE INSTRUCTIONS CAREFULLY, EACH TIME YOU USE THE CHARGING EQUIPMENT.
Follow these instructions and those published by the battery and vehicle manufacturers and the manufacturer of any equipment
you intend to use in the vicinity of the battery. Remember to review warning marks on all products and on engines.
1.2. GENERAL SAFETY INSTRUCTIONS
Familiarise yourself with the application, limitations and potential hazards relating to the chargers. Also refer to the vehicle
manufacturer’s hand book. IF IN ANY DOUBT CONSULT AN ELECTRICIAN.
Ensure the charger is in good order and condition before use. If in any doubt do not use the unit and contact an electrician.
Only use recommended attachments and parts. To use non-recommended items may be dangerous and will invalidate your warranty.
Use the charger in the horizontal position only and ensure it is placed on a stable surface.
Ensure the charger is ‘Off’ before attaching/detaching the power clamps to/from the battery.
Keep tools and other items away from the engine and ensure you can see the battery and moving parts of the engine clearly.
Ensure the voltage on the charger is set to the same voltage as the battery. Check position of positive battery cable.
If the 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 section 1.3).
The cables may become hot with excessive use. If so, allow a few minutes for them to cool down before attempting to re-use.
If the charger receives a sharp knock or blow the unit must be checked by a qualified service agent before using.
If the battery terminals are corroded or dirty clean them before attaching the power clamps.
Keep children and unauthorised persons away from the work area.
DO NOT dis-assemble the charger for any reason. The charger must only be checked by qualified service personnel.
DO NOT try to charge a non-rechargeable battery.
DO NOT try to start an engine, or to charge a battery, if the battery is *frozen. (* In prolonged extremely cold conditions a battery could
become frozen. A frozen battery could explode if charged. Cold cranking will put additional strain on the engine and the battery.)
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 parts of the vehicle.
DO NOT cross connect power leads from charger to battery. Ensure positive (+) (RED) is to positive and negative (-) BLACK is to
negative. In the unlikely event symbols cannot be distinguished, on most modern vehicles the negative terminal is the one directly
connected to the vehicle bodywork.
DO NOT pull the cables or clamps from the battery terminals and DO NOT remove power clamps while the charger is ‘On’.
DO NOT use the charger outdoors, or in damp or wet locations and DO NOT operate within the vicinity of flammable liquids or gases.
DO NOT use the charger inside vehicle or inside engine compartment. Ensure there is sufficient ventilation and do not cover or
obstruct charger ventilation louvres.
DO NOT use this product to perform a task for which it is not designed.
WARNING! If a fuse blows, ensure it is replaced with an identical fuse type and rating.
When not in use, store the charger carefully in a safe, dry, childproof location.
