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, as well
as suitable gloves, when working with this tool.
WARNING: ENSURE gloves and clothes worn do not have loose threads that could get caught
by the rotating spindle and drag your hand or head into the rotating spindle causing severe injury.
It is recommended to wear gloves that are not fabric based.
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 move downwards towards the table. 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
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.
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.
ON/OFF switch
To start the drill, press the 'I' Button of the ON/OFF Switch (3)
To stop the drill, press the 'O' Button
WARNING: Do not operate this tool for longer than 15 minutes in one continuous operation and
allow the tool to cool between long operations.
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 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/spindle. 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
• Ensure that drill bits are suitable for wood and have a maximum rpm above the set speed of
the drill
WARNING: DO NOT inhale wood dust. Wear adequate breathing protection. Some wood
dusts may be toxic.
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
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.
• 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
Accessories
• A full range of accessories including drill bits, holesaws, wire brushes etc. is available from your
Silverline dealer
• Drill Press Vice 65mm
• Drill Press Vice 100mm
• Quick Release Drill Vice 100mm
Maintenance
WARNING: Always disconnect from the power supply before carrying out
any maintenance/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
Lubrication
This drill press comes correctly lubricated with grease and oil for the spindle mechanism parts which
will be sufficient for years of normal occasional use. However if the drill press is frequently used
it may need to be re-lubricated on a yearly basis. Instructions on dismantling and re-assembling
the spindle section are beyond the scope of this manual. However, general advice for lubrication
is as follows;
1. After dismantling, clean the components removing the old lubrication and check for component
excessive wear or damage
2. Lubricate the Bearings (19) with a good quality lithium-based grease. For sealed bearings check
functionality and grease them externally. Fill the Spline Sleeve (18) and Spindle Sleeve (20) with
grease and ensure the Spindle (21) is also greased
3. A light coating of engine oil can be applied for parts where grease cannot be applied or where
there is surface friction
Cleaning
WARNING: ALWAYS wear protective equipment including eye protection and gloves when cleaning
this tool.
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly, and
shorten the device's service life
• Clean the body of your machine with a soft brush, or dry cloth
• Never use caustic agents to clean plastic parts. If dry cleaning is not sufficient, a mild detergent
on a damp cloth is recommended
• Water must never come into contact with the tool
• Ensure the tool is thoroughly dry before using it
• If available, use clean, dry, compressed air to blow through the ventilation holes
