ELECTRICAL SAFETY

WARNING! It is the user’s responsibility to check the following:
Check all electrical equipment and appliances to ensure that they are safe before using. Inspect power supply leads, plugs and all electrical connections for wear and damage. Sealey recommend that an RCD (Residual Current Device) is used with all electrical products. You may obtain an RCD by contacting your local Sealey dealer. If the product is used in the course of business duties, it must be maintained in a safe condition and routinely PAT (Portable Appliance Test) tested.
Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.

1. Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that they are secure.

2. Important: Ensure that the voltage rating on the appliance suits the power supply to be used and that the plug is fitted with the correct fuse – see fuse rating in these instructions.

   • DO NOT pull or carry the appliance by the power cable.
   • DO NOT pull the plug from the socket by the cable.
   • DO NOT use worn or damaged cables, plugs or connectors. Ensure that any faulty item is repaired or replaced immediately by a qualified electrician.

3. This product is fitted with a BS1363/A 13 Amp 3 pin plug.
   If the cable or plug is damaged during use, switch the electricity supply and remove from use. Ensure that repairs are carried out by a qualified electrician.
   Replace a damaged plug with a BS1363/A 13 Amp 3 pin plug. If in doubt contact a qualified electrician.

GENERAL SAFETY

• WARNING! Disconnect drill from mains power before changing accessories, servicing or performing any maintenance.
  DO

• Maintain the drill in good condition (use an authorised service agent).

• WARNING! Keep all guards and holding screws in place, tight and in good working order. Check regularly for damaged parts. A guard or any other part that is damaged must be repaired or replaced before the tool is next used, to ensure that it will operate properly and perform its intended function. The safety guard is a mandatory fitting where drill is used in premises covered by the Health & Safety at Work Act.
  DO

ASSEMBLY

Notes:

• Diagrams are illustrative and may differ in detail from your drill.
• Numbers in brackets refer to item numbers in the Parts List and Diagram

1. Place the column (4) on the base (2), align holes and secure with the bolts (5) provided.

2. Insert worm gear (9) into table bracket, meshing it with the lift gear (7) (fig.1).

3. Fit table bracket (6) onto column (4) together with rack (15) (fig.2), engaging gear (7) in bracket with rack.

4. Install the rack collar (93) and tighten set screw (94) firmly (fig.3).

5. Fit the table adjusting handle (10) (fig.3.A) and lock handle (14) (fig.3.B).

6. Tighten the adjusting handle set screw (11) onto the flat on the worm gear shaft (9).

7. Install the table (16) and table lock handle (14) (fig.4).

8. Ensure that the column head assembly (83) is approximately midway between the motor (69) and the spindle housing (25) and then insert locking shoe (88) into column head (84) (fig.5).

9. Place the head assembly over the column (4) and slide column head (84) down onto column. Tighten lock handles (fig.6).
   WARNING! If the column head assembly is not positioned midway there is a risk that the whole drill assembly may become unstable when the head assembly is fitted.

10. Screw the three feed handles and knobs (37/38) into the hub (35) of the pinion shaft.

11. To install chuck (46) open the chuck jaws completely by turning the chuck key (46A) counter-clockwise. Hold chuck on spindle and tap into place on taper with a hammer (fig.7).

12. Loosen clamp screw on safety guard mounting collar, pass guard up over chuck and fit collar round flange of quill (40). Ensure guard pivot is central and tighten clamp screw (see fig.8).

13. Open pulley cover (48), loosen butterfly set screw (36) on motor adjustment and fit belt (73) to pulleys(19/79). Pull motor (69) back to tension belt and retighten screw (36).

DRILL MOUNTING

WARNING! For stability and safety it is imperative that the drill base is securely bolted to the workbench (GDM790BR) or floor (GDM1630FR).

1. Ensure that the mounting surface is capable of supporting the drill together with the weight of the heaviest likely workpiece.

OPERATION

WARNING! Ensure the drill is unplugged from the mains power supply before commencing.

1. INSTALLING DRILL BIT

2. Insert drill bit into chuck jaws to 1” (25mm) deep (avoid inserting small bits too far) and centre bit in chuck before tightening.

3. ADJUSTING THE TABLE

4. To adjust table up or down, loosen lock handle (fig.3.B) then turn bracket handle (fig.3.A). Once at correct height tighten lock handle.

5. To adjust table tilt, loosen the work table bolt (fig.3.C), adjust table to the desired angle, then re-tighten bolt.

6. To turn the table around the column, loosen the rack collar slightly, then loosen the lock handle (fig.3.B).

7. Turn the table to the desired position then secure the lock handle and rack collar.

8. ADJUSTING THE SPEED
   NOTE: the belt cover is fitted with a micro-switch to prevent drill operation with the cover open.

9. Open the pulley cover (48) and loosen the motor adjustment screw (36).

10. Choose the speed for the drilling operation (see drill speed chart – Section 7) and move the belt to the correct pulley grooves for that speed, as shown on the pulley chart – Section 7.

11. BELT TENSION

12. With the motor adjustment clamp screw (36) loose and using hand pressure on the motor, set tension so that belt give is no more than 10mm each side, at centre span, under finger pressure. Tighten clamp screw (36).

13. POSITIONING THE WORKPIECE

14. Rest the workpiece on a piece of wood to prevent the drill bit damaging the table when it breaks through the workpiece. The wood should rest on the table so that one end of it is against the left side of the column. This will prevent the wood spinning when the drill bit breaks through into it.

15. For small workpieces that cannot be clamped to the table, use a drill vice (not included). Vice must be bolted to table.

16. SETTING THE DRILL DEPTH

17. Use the scale on the side of the drill head near the drill handle.

18. Loosen locking screw (36) and set the scale to the depth required. Tighten locking screw.

19. When ready to drill, simply pull the feed handle. The drill will stop at the set depth.

20. SETTING THE DRILL HEAD

21. Fore and aft movement

22. Loosen clamping lever (fig.9.A) and turn feed knob (fig.9.B) to move head to the required position. Re-tighten clamping lever.

23. Horizontal rotation

24. Loosen clamping lever (fig.10.A) and rotate head on column to required position (360° rotation is available). Re-tighten clamping lever.

25. Tilting

26. Loosen clamping lever (fig.9.A), Pull out and turn – to hold out – vertical lock (fig.10.B). Head may now be tilted up to 45° clockwise and 90° anticlockwise. Angular position is shown by line (fig.9.C) against scale (fig.9.D). When set, re-tighten clamping lever. After returning head to the vertical position always re-engage the vertical lock.

27.  Head square to table

28. Confirm that head is in the ‘vertical’ position, that the vertical lock (fig.10.B) is engaged and that the clamping lever (fig.9.A) is tight.

29. Using a spirit level check that table is horizontal and, if necessary, adjust as in para.6.2.2.

30. Clamp a straight rod, or a drill bit, in the chuck and use a machinist’s square to check that the rod is perpendicular to the table.

Adjust drill head as necessary by loosening the two set screws (fig.11.A) either side of the spindle housing and rotating the housing on the horizontal tube (81). When correctly positioned, re-tighten set screws.

DRILL SPEEDS

The chart below shows recommended drill speeds for various bit diameters and materials. Select the available drill speed that is the same as, or nearest to, the one recommended for the task in hand.

Drill Speed (rpm)

MAINTENANCE

1. Clean the drill after each use. A coat of automobile-type wax applied to the table and column will help to keep the surfaces clean.
2. Blow out any dust that may have accumulated in the motor.
3. Periodically lubricate the table elevation rack/gear/worm mechanism.
4. BELT CHANGING Please note that an instructional video for this product is available to view on our YouTube channel.
5. Open the pulley cover (48) and loosen the motor adjustment screw (36).
6. With the tension released, remove the belt and fit a replacement to the same specification as the original.
7. With the motor adjustment clamp screw (36) loose and using hand pressure on the motor, set tension so that belt deflection is no more than 10mm each side, at centre span, under finger pressure. Tighten clamp screw (36).
