1. Disconnect the drill press from its power supply before changing the speed.
2. Remove the single Phillips screw that secures the Pulley Cover (4). It is above the Drive Belt
Tension Adjuster. Open the Pulley Cover.
3. The speed is adjusted by the belt that connects the Spindle Pulley (8) and the Motor Pulley (9).
4. To move the belt, loosen the Drive Belt Tension Adjuster and pull the Motor (2) towards the front
of the drill.
5. Position the belt onto the desired step on the pulleys according to the table above or the
provided table inside the lid of the Pulley Cover.
IMPORTANT: Only operate the drill with the belt level. Operating the drill press with the belt angled
will result in serious damage to the tool and will invalidate the guarantee.
6. Lever the motor away from the front of the drill to tension the belt, then tighten the Drive Belt
Tension Adjuster and refit the Pulley Cover securing screw.
Note: Low tension will cause the belt to slip and may cause the drill bit to lock in the material. Over
tensioning will cause excessive wear and noise. Correct tensioning is tensioning at the first point
where the belt can't slip in use and will provide maximum life for the belt. As the belt ages and
stretches tension will have to be increased again. Eventually a replacement belt may be required.
Note: The Pulley Cover has a safety device which prevents the tool working if the Pulley Cover is
not closed and can be seen inside the cover. If the tool fails to operate make sure the Pulley Cover
is closed correctly.
Operation
WARNING: ALWAYS wear eye protection, adequate respiratory and hearing protection when
working with this tool.
Plunge handles
The Plunge Handles (11) should always be used to feed the drill bit into the material. Pull down on
the handle to make the Chuck (7) move downwards towards the Table (13). The plunge mechanism
will automatically return to a high position removing the drill bit from the workpiece if the Plunge
Handles aren't turned. Always control this ascent, do not let go of the Plunge Handles in use.
Operating the chuck
WARNING: Never fit any attachment with a maximum speed lower than the no load speed of
the belt position speed that the drill has been set to.
The Chuck (7) can be opened or closed by using the provided chuck key. It is capable of securing drill
bits with shanks from 1.5 - 13mm.
Note: Ensure that the Chuck is fully tightened before attempting to drill as it could cause severe and
permanent damage to the Chuck and may invalidate the guarantee.
ON/OFF switch
WARNING: Do not operate this tool for longer than 30 minutes in one continuous operation and
allow the tool to cool between long operations.
To start the drill, press the 'I' button of the ON/OFF Switch (3).
To stop the drill, press the 'O' button.

Table
The Table (13) can be adjusted for height, rotation and tilt. It has 2 slots for securing a vice (not
supplied) to the Table surface and a central hole for allowing a drill bit to pass through the material
being drilled without damaging the surface of the Table.
Position adjustment
• Loosen the Table Locking Handle (12).
• Move the Table (13) to the height and rotation position for the required hole in the material
being drilled.
• Tighten the handle once Table position has been confirmed.
• To adjust tilt, loosen Table Tilt Bolt (17) with a spanner (not supplied) and adjust using the Table
Tilt Angle Scale (16) to give the approximate required angle or set the Table exactly level using a
spirit level. Then re-tighten the bolt.
• Note: Ensure that the Table is securely tightened in position prior to use.
Drilling depth
You can adjust the drilling depth by limiting the movement of the Chuck (7)/Spindle (21).
• Adjust the 2 nuts on the thread parallel to the Drilling Depth Gauge (5). Set between 0 and
50mm as shown on the gauge.
• Locking the 2 nuts together at maximum height will give the full 50mm of travel.
CAUTION! Applying excess pressure does not result in faster or more efficient drilling. If the
pressure applied to the drill has a noticeable effect on the speed of the drill then reduce the
pressure. Overloading the drill will reduce its service life.
As the drill bit penetrates the material being drilled, it may 'catch' or 'snag'. This may cause the
machine to suddenly 'kick'. To prevent any possibility of injury always ensure the material is held
securely by a vice or a clamp and use sharp drill bits.
Drilling wood
WARNING: DO NOT inhale wood dust. Wear adequate breathing protection. Some wood dusts
may be toxic.
• Ensure that drill bits are suitable for wood and have a maximum rpm above the set speed of
the drill.
Drilling metal
• Ensure that drill bits are suitable for the grade of metal being drilled and have a maximum rpm
above the set speed of the drill.
• Only apply moderate pressure to the drill bit, ensuring efficient cutting and prolonged drill
bit life.
• Use a countersink bit to remove sharp burrs from the hole, preventing cuts and other kinds
of injury.
WARNING: The drill bit and the workpiece will become very hot when drilling metal. DO NOT
touch the bit and never allow it to come into contact with combustible materials when hot. Always
use a suitable lubricant or cutting fluid, and drill at appropriate speeds.
Accessories
• A full range of accessories including vices, drill bits, holesaws, wire brushes etc. is available from
your Silverline stockist.
• Spare parts can be purchased from your Silverline dealer or online at www.toolsparesonline.com
Maintenance
WARNING: Always disconnect from the power supply before carrying out any maintenance
or cleaning.
General inspection
• Regularly check that all the fixing screws are tight. They may vibrate loose over time.
• Inspect the supply cord of the tool, prior to each use, for damage or wear. Repairs should be
carried out by an authorised Silverline service centre. This advice also applies to extension cords
used with this tool.
