FEATURES
This 305 mm disc sander is ideal for finish fitting, altering bevel angles, sanding
convex curves - ‘to the line’, and sanding end grain, without burning etc.
The machine is provided with a work table which is capable of tilting to 45
degrees, and a mitre gauge, in which the work may be held, and which
moves in a mitre gauge slot, parallel to the disc. The Mitre gauge is capable of
adjustment to 60 degrees. The table must ALWAYS be perfectly secure before
starting work.
Considerable dust is produced when using this machine and it is most
important that a suitable face mask is worn at all times. We also strongly
recommend that a dust extractor is fitted to the outlet provided, and similarly,
used at all times.
If you are not familiar with sanding machines, it is strongly recommended that
you consult a qualified person, or obtain relevant tutorials. Like all power tools,
this machine can be extremely dangerous in the wrong hands or if used
incorrectly. Used correctly however, it is a highly efficient and intensely labour
saving device.

OPERATING INSTRUCTIONS
ADJUSTING THE WORK TABLE
1. Adjust the work table to the
desired angle by slackening the
two table clamps, one either side,
2. Move the table to the required
angle.
3. Retighten the clamps.
• The clamps are spring loaded.
Turn the lever clockwise to
clamp, as far as possible.
• Then pull the lever out against
spring pressure which allows the
lever to be turned
anticlockwise without
unclamping.
• Allow the lever to spring inwards again, then proceed to turn it
clockwise once more.
NOTE: Repeat the process until the table is securely clamped.....but DO
NOT overtighten, otherwise damage to the mechanism will occur.

TO STOP THE DISC SANDER
1. Press the RED STOP button marked
‘O’ and wait for the disc to stop

dust.
• Take care, the disc may take
some time to come to a full
stop.
• If required, press the brake on
top of the disc sander to help
slow the disc.
MITRE GAUGE
If the angle is critical, a mitre gauge
should be used between the table
and disc to ensure accuracy. For
right angles, simply slide a square on
the table, up to the disc, and adjust
accordingly. The angle should be
correct when slight pressure is placed
on the table.
For greater accuracy, the mitre
gauge is used so that the work may
be held at a required angle and
moved across the disc as shown.
Use a slight pressure ONLY... let the
disc do the work. Pressure should be
on the DOWNWARDS direction of
motion of the disc ONLY. i.e. on the
left half of the disc as shown.
NOTE: Applying the workpiece to
the right hand side of the
disc may cause kickback.
