ADDITIONAL PRECAUTIONS FOR BELT & DISC SANDERS
1. ALWAYS wear ear protectors/defenders when using this machine.
2. ALWAYS wear a dust mask when using this machine. Be aware of harmful or
toxic dust produced when sanding some woods, paint, etc.

4. Always check to ensure that the table, belt support and attachments are
secure before starting.
5. ALWAYS maintain a clearance of 1.5-2mm between the table and the
sanding belt or disc.
6. ALWAYS hold the workpiece firmly so that it cannot be pulled from your
hands.
7. ALWAYS feed the workpiece against the direction of rotation of the disc. i.e
the LEFT side of the disc.
8. ALWAYS keep the mains cable well away from the machine and ensure an
adequate electrical supply is close at hand so that the operation is not
restricted by the length of the cable.
9. ALWAYS use a dust extraction device, properly connected to the dust
extraction port.
10. ALWAYS ensure that nails or any foreign objects have been removed from a

DUST EXTRACTION
The sander is provided with a dust extraction facility. Please note however,
that this does not preclude the user from wearing a face mask to prevent the
inhalation of dust particles.
It is an EEC requirement that a dust extraction facility be provided on power
tools, however, due to the nature of the sander, some of the dust produced
will be forced into the surrounding atmosphere and will not be collected.

in the Upper Disc Cover to the
extent that the Locking Levers
can be screwed in as shown
overleaf, ensuring flat washers are
used on the locking lever threads.

3. Secure with four screws (arrowed).
FEET
The four feet may be very gently eased into the holes at the base of the
machine. Alternatively, the machine may be mounted on a workbench or a
wooden base, using the four holes in the base as mounting holes. In order to
maintain complete stability when in use, the wooden base should be secured
to a workbench using ‘G’ clamps.
ADJUSTMENTS BEFORE USE
BELT TABLE ADJUSTMENT
1. With the belt correctly tensioned
(See Maintenance), adjust the
Belt Support so that it is square
and bears very lightly on the back
of the Sanding Belt.
2. Ensure the two hex socket head
securing screws (arrowed) are
tight. A hex. socket wrench is
provided.
3. Slacken the Table Locking Lever
and position the table so that a
gap of 1.5 - 2 mm exists between
the slot in the table and the belt, then lightly secure the table using the
locking lever.

4. Place an engineers square on the
table so that it butts up against
the belt, then unlock the adjuster
by unscrewing the locknut at B.
5. Screw the adjuster A, clockwise or
anticlockwise whilst bearing down
on the table at a point adjacent
to screw A, until the square
indicates that the table is at right
angles.
6. Lock the adjuster, ensuring the nut is tight, then, maintaining pressure on
the table, finally secure the table using the locking lever. by turning
anticlockwise.
7. Finally, check to ensure the gap between the table and belt is between 1.5
- 2 mm.
8. It is possible to set the table to any angle up to 45 degrees, simply by
slackening the locking lever and positioning the table using a protractor or
angle setter, then retightening the locking lever.
DISC TABLE ADJUSTMENT
1. Place an engineers square on the
table and slacken the locking
levers slightly.
2. Adjust the table so it is at right
angles to the disc, using the
square, then tighten the levers.
3. If necessary, adjust the pointer,
adjacent to the angle indicator
beneath the table, so that it
registers zero.
4. Slacken the upper disc cover securing screws (A on page 8) using the
wrench supplied, and adjust so that a gap of 2-3mm exists between the
disc and the table and the table is square. Tighten the securing screws.
5. It is possible to set the table to any angle up to 45 degrees, simply by
slackening the locking levers and positioning the table using the angle
indicator, then retightening the locking levers. If the angle is critical, a
protractor or angle setter should be used.
6. If required, slide the quadrant into its groove in the table.
NOTE: The quadrant may be used to hold a workpiece at any desired
angle for sanding that angle with accuracy.

OPERATION
IMPORTANT: Ensure that ALL components are secure, ALL correct
adjustments have been carried out, and ALL safety precautions have been
observed BEFORE plugging the machine into the mains supply, and
switching ON.
1. Attach a vacuum cleaner or
other dust extraction device to
the relevant extraction port
(depending upon the medium to
be used) and switch it ON.
2. Switch the machine ON by
pressing the Green ON button.
3. If using the belt, check to ensure it
is tracking properly...adjust if
necessary.
4. Holding the workpiece firmly, place it on the table and gently slide it into
contact with the belt or disc. Do not force it, only a light pressure is
required.
IMPORTANT: When using the sanding disc, ALWAYS use the left half of the
disc ONLY, i.e. that, side where the direction of rotation of the disc is down
towards the table.
MAINTENANCE
Always inspect the sander before use and ensure it is in top condition.
Ensure all air vents are clear. (Use compressed air to clean the machine where
possible).
Check the power cable to ensure it is sound and free from damage. Avoid
using solvents when cleaning plastic parts, (most plastics are susceptible to
damage from the various types of commercial solvents).
All bearings in this tool are lubricated with sufficient high grade lubricant for
the machine’s lifetime under normal operating conditions, therefore no further
lubrication is required.

CHANGING THE SANDING BELT
1. Remove the belt table
completely by unscrewing and
removing the table locking lever.
2. Remove the two side cover
securing screws (A), followed by
the upper roller pivot screw (B),
then pull off the side cover.
3. Turn Adjuster (C) anti-clockwise,
sufficiently for the sanding belt to
be slipped off the rollers.
4. Replace the sanding belt ensuring
it is central about the rollers, and
the arrow (D) is pointing down
towards he table.
5. Turn the belt by hand and observe
how it moves on the rollers,
indicated by its position on the
support.
6. This will determine whether or not
it is tracking correctly. If it moves
sideways, turn the adjuster (C), so
that it stabilises over the middle of
the support.
• At this point the belt is tracking
properly. It is tensioned auto-
matically & cannot be adjuste
• Turning the adjuster clockwise will cause the belt to move one
way...turning it anticlockwise and it will have the opposite effect.
CHANGING THE DISC
1. Remove the disc table and lower cover/dust extraction port.
2. Slacken the two screws securing the upper disc cover and slide it back.
3. Using a sharp instrument, tease off a portion of the sanding disc, sufficient
for it to be grasped by hand and peeled off. Remove all residual adhesive
and finally clean the disc with solvent.
4. Peel the backing from the replacement sanding disc and fix to the disc
ensuring it is central. Press it firmly to ensure it is secure.
5. Replace the table and lower disc cover, and adjust gap between table
and disc by positioning and securing the upper disc cover.
