Sealey Bg250xl User manual

1.1. ELECTRICAL SAFETY. p

WARNING! It is the users responsibility to read, understand and comply with 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 also 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 electrician, at least once a year, using a Portable Appliance Tester (PAT).

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. Ensure the insulation on all cables and the product itself is safe before connecting to the mains power

supply. See 1.1.1. & 1.1.2. above and use a Portable Appliance Tester (PAT).

1.1.4. Ensure that cables are always protected against short circuit and overload.

1.1.5. Regularly inspect power supply, leads, plugs for wear and damage and power connections,

to ensure that none is loose.

1.1.6. Important: Ensure the voltage marked on the product is the same as the electrical power supply

to be used and check that plugs are fitted with the correct capacity fuse. A 13 amp plug may require

a fuse smaller than 13 amps for certain products, see fuse rating at right.

1.1.7. DO NOT pull or carry the powered appliance by its power supply lead.

1.1.8. DO NOT pull power plugs from sockets by the power cable.

1.1.9. DO NOT use worn or damaged leads, plugs or connections. Immediately replace or have repaired by

a qualified electrician. A U.K. 3 pin plug with ASTA/BS approval is fitted. In case of damage, cut off

and fit a new plug according to the following instructions (discard old plug safely).

(UK only - see diagram at right). Ensure the unit is correctly earthed via a three-pin plug.

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 cable outer insulation extends beyond the cable restraint and that the restraint is tight.

Double insulated products are fitted with live (BROWN) and neutral (BLUE) wires only. Double insulated products are always marked with

this symbol . To re-wire, connect the brown & blue wires as indicated above. DO NOT connect the brown or blue to the earth terminal.

1.1.10. Cable extension reels. When a cable extension reel is used it should be fully unwound before connection. A cable reel with an RCD

fitted is recommended since any product which is plugged into the cable reel will be protected. The section of the cores of the cable

is important and should be at least 1.5mm2, but to be absolutely sure that the capacity of the cable reel is suitable for this product and

for others that may be used in the other output sockets, we recommend the use of 2.5mm2section cable.

5.1. Pre use Inspection.

pWARNING! INSPECT THE GRINDER BEFORE OPERATING THE MACHINE. ENSURE THE GRINDER IS UNPLUGGED FROM

THE MAINS POWER BEFORE COMMENCING THE INSPECTION.

5.1.1. Check the tool rests are securely fixed at a maximum of 1.5mm from the grinding stone.

5.1.2. Check that eye shields are in good condition, are secure and that you can see through them clearly.

5.1.3. Turn the grinding stones by hand and check for any damage. Check they do not touch the tool rests and are correctly aligned.

If any of the above checks fail, replace, repair, or adjust as necessary before starting the grinder.

5.2. Stone Use.

Depending on the model, grinders are supplied with one or two aluminous oxide stones. Stones have two grades, fine are preferred

for hard materials and a coarse for soft materials.

When grinding, should surface of the stone become loaded (coated with particles of the material being ground) it is probably the

wrong grade of stone for the job.

Important reminder: Grinding stones MUST ONLY be assembled by a person holding a grinding wheel certificate. See Section 4.

5.3. Using the Grinder.

pWARNING! Before commencing work, ensure you read, understand and apply the Safety Instructions.
