Sealey GDM150B 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 or 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 professional 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, 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 appliance operators. 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 and plugs for wear or damage and 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 (subject to 1.1.10. below).
1.1.7. DO NOT pull power plugs from sockets by the power cable.
1.1.8. DO NOT use worn or damage leads, plugs or connections. Immediately replace or have repaired by a
qualified electrician. Where 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 the live terminal ‘L’.
c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
After wiring, check there are no bare wires, that all wires have been correctly
connected, that the cable outer insulation extends past the cable restraint and that
the cable restraint is tight.
Double insulated products are often 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 wires to the earth terminal.
1.1.9. NOTE: If this product requires more than a 13 amp electrical supply, then NO plug is fitted. You must therefore contact a qualified
electrician to ensure a 30 amp fused supply is available. We recommend you discuss the installation of a industrial round pin plug and
socket with your electrician.
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 in 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 any that may be used in the other output sockets, the use of 2.5mm² section is recommended.

6.1. Install drill bit
6.1.1. Insert drill bit into chuck jaws to 1" (25mm) deep (avoid inserting small bits too far) and centre bit in chuck before tightening.
6.2. Adjusting the table
5.2.1. To adjust table up or down, loosen clamp bolt (fig.2.B) then turn bracket handle (fig.2.A). Once at correct height tighten clamp bolt
(fig.2.B).
6.2.2. To adjust table tilt, loosen the work table bolt (fig.2.C), adjust to the desired angle using the angle scale, then retighten.
6.2.3. To turn the table around the column, loosen the rack collar slightly, then loosen the clamp bolt (fig.2.B).
Turn the table to the desired position then secure the clamp bolt and rack collar.
6.3. Adjusting the speed
6.3.1. Open the pulley case and loosen the belt tension lock screws (fig.6.A).
6.3.2. Choose the speed for drilling operation (see drill speed chart) and move the belts to the correct
position for that speed, as shown on the chart inside the pulley cover.
6.4. Belt tension
6.4.1. With the belt tension lock screws (fig.6.A) loose and using hand pressure on the tensioning lever (fig.5.C),
set tension so that belt give is no more than 1/2" (13mm). Tighten lock screws.
Note that there are two lock screws, one each side of the head.
6.5. Positioning the workpiece
6.5.1. Use a piece of wood to rest the workpiece on. The drill bit may break through the workpiece and damage the table otherwise.
The wood should rest on the table so that one end of it is against the left side of the column. When the drill bit breaks through the
workpiece, it will contact the wood and cause it to spin. Resting the wood against the column will help prevent this.
6.5.2. For small workpieces that cannot be clamped to the table, use a drill vice (not included). Vice must be clamped or bolted to table.
6.6. Setting the drill depth
