Sealey SG125EU User manual

PLEASE NOTE: THESE INSTRUCTIONS RELATE TO UK LEGISLATION - IT IS THE USER’S RESPONSIBILITY THAT COUNTRY AND
LOCAL EQUIVALENT LEGISLATION IS ADHERED TO WHEN USING THIS ANGLE GRINDER.
1.1. ELECTRICAL SAFETY
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 that 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) is used. It is particularly important to use an RCD with portable products that are plugged into a supply
which 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 dealer. You must also read and understand the following instructions concerning electrical safety.
1.1.1 The Electricity at Work Act 1989 requires that all portable electrical appliances, if used on business premises, are tested by a qualified
electrician, 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 those appliances and
the safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3 Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.1.1 and 1.1.2 and
use a Portable Appliance Tester.
1.1.4 Ensure that cables are always protected against short circuit and overload.
1.1.5 Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that none is loose.
1.1.6 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. The fuse rating for this product is 13amp.
1.1.7 DO NOT pull or carry the appliance by the power cable.
1.1.8 DO NOT pull the plug from the socket by the cable.
1.1.9 DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty item repaired or replaced by a qualified
electrician. When a 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 applicable in the EU country the equipment is being used in.
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 above (b,c) - DO NOT connect either wire
to the earth terminal.
1.1.10 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.
