1. SAFETY INSTRUCTIONS
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 1.1.1.
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 damaged leads, plugs or connections. Immediately replace or repair by qualified persons.
1.1.9 The following information is for fitting a 13 amp plug which is only suitable when using the unit as a charger. If the unit is
to be used for starting it must be fitted with a 16 or 32amp plug or be hard wired into a 32A protected outlet. IN ALL CASES
CONSULT A QUALIFIED ELECTRICIAN TO ASCERTAIN THE CORRECT PLUG/FUSE COMBINATION FOR YOUR APPLICATION.
a) Connect the green/yellow earth wire to the earth terminal ‘E’.
b) Connect the brown live wire to 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 external insulation
extends beyond the cable restraint and that the restraint is tight.
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.
DANGER! BE AWARE, LEAD-ACID BATTERIES CONTAIN CORROSIVE SUBSTANCES. 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 starter/chargers. Also refer to the vehicle
manufacturer’s handbook. IF IN ANY DOUBT CONSULT AN ELECTRICIAN.
Ensure that the starter/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 starter/charger in the vertical position only and ensure it is placed on a stable surface which will adequately support the weight.
Ensure the starter/charger is ‘OFF’ before handling the power clamps.
Ensure the starter/charger is ‘OFF’ before attaching/detaching the power clamps to/from the battery.
Keep tools and other items away from the engine and ensure that you can see the battery and moving parts of the engine clearly.
Ensure the voltage on the starter/charger is set to the same voltage as the battery.
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.
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 starter/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 starter/charger for any reason. The starter/charger must only be checked by qualified service personnel.
DO NOT try to charge a non-rechargeable battery.
DO NOT try to start engine, or to charge the battery, if the battery 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.
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 starter/charger to battery. Ensure positive (+ or RED) is to positive and negative (- or BLACK) is to negative.
If symbols cannot be distinguished, remember that the negative terminal is the one directly connected to the vehicle bodywork.

2.1 INTRODUCTION
A hybrid starter/charger utilising traditional transformer power supply with advanced
electronic control. The unit features digital read-out of the battery condition or battery
charging current and current control setting to allow batteries to be fast-charged. Advanced
electronics provide battery conditioning cycle for badly discharged batteries. Once a battery
has been brought up to fully charged status, the Tronic function maintains the battery in
this condition by reading the charged status of the cells. The unit also has the power to start
vehicles fitted with batteries up to 700Ah.
