1.3. MAINS POWER ELECTRICAL SAFETY (In relation to the battery charger)
  WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:
You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any
other connectors for wear or damage. You must ensure the risk of electric shock is minimised by the installation of appropriate safety
devices. A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a
Residual Current Device (RCD) be used. It is particularly important to use an RCD with portable products that are plugged into a supply
that is not protected by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual Current Device by contacting
your Sealey stockist. You must also read and understand the following instructions concerning electrical safety.
1.3.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by a qualified
electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.3.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances
and the safety of the appliance operator. If in any doubt about electrical safety, contact a qualified electrician.
1.3.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.3.1 and 1.3.2
and use a Portable Appliance Tester.
1.3.4. Ensure that cables are always protected against short circuit and overload.
1.3.5. Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure none is loose.
1.3.6. 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 right.
1.3.7. DO NOT pull or carry the appliance by the power cable.
CP2450MH Issue1 - 06/03/17
CP2450MH Issue

1.3.8. DO NOT pull the plug from the socket by the cable.
1.3.9. DO NOT use worn or damage cables, plugs or connectors. Immediately have any faulty item
repaired or replaced by a qualified electrician. When an ASTA/BS approved UK 3 pin plug is
damaged, cut the cable just above the plug and dispose of the plug safely.
Ensure that the double insulated charger is correctly connected via a three-pin plug, as follows:
a) Connect the Brown live wire to live terminal ‘L’.
b) Connect the Blue neutral wire to the neutral terminal ‘N’.
c) After wiring, check that there are no bare wires, that all wires have been correctly connected,
that the cable outer insulation extends past the cable clamp and that the clamp is tight. Note that
the earth pin ‘E’ remains unconnected.
1.3.10.If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted is
preferred since any appliance plugged into it will be protected. The cable core section is important and
should be at least 1.5mm², but to be absolutely sure that the capacity of the reel is suitable for this
product and for others which may be used in the other output sockets, we recommend the use of 2.5mm² section cable. If extension reel is
to be used outdoors, ensure it is marked for outdoor use.
1.4. BATTERY CHARGER SAFETY INSTRUCTIONS
WARNING! DO NOT attempt to charge any battery other than that supplied for the wrench. Other types of batteries may explode!
All mains electrical supply safety features must be followed as described in 1.3 above.

 WARNING! Ensure that you read, understand and apply the safety instructions before use.
3.2. USING THE WRENCH.
3.2.1. Use only impact sockets which are specifically designed for use with an impact wrench. The use of normal chrome vanadium sockets
is dangerous, since these are more brittle and are liable to shatter.
3.2.2. Fit the socket to the wrench by snapping it onto the square drive (fig.1.1).
3.2.3. Fit the battery pack to the wrench by aligning the tongue on the battery with the groove in the housing and slide it into place. Ensure
that the battery pack is firmly located, you will hear an audible click when it has locked into position.
3.2.4. Select the required direction of rotation. To change direction, push switch (fig.1.3) to the left or right. Familiarise yourself with this
operation before use. DO NOT attempt to change the direction of rotation whilst the trigger (fig.1.6) is depressed.
When the wrench is not in use, use the same switch to lock off the trigger by placing the switch in the middle position.
3.2.5. When tightening, release the trigger as soon as the impact sound is heard. Take care not to over-torque small fixings.
Note: On critical fixings, final tightening should be carried out using a torque wrench, setting it according to the product or the
vehicle manufacturer’s specifications.
4. MAINTENANCE
4.1. CLEANING.
Keep the outer case of the wrench clean and free from grease. DO NOT wash with water or use solvents or abrasives, use a damp cloth.
