Rating

Rating Description
Hobby: Suitable for Weekend DIY'ers and woodworking enthusiasts.
Generally lighter weight machines with lower power ratings and smaller tooling capacities. Typically only
ever used by one person for short periods of time or longer periods of time infrequently. Machinery should
be well maintained in a clean, dry environment such as a home workshop, garage or timber shed.
Expected maximum use of 100 hours annually.
Please Note: Using a product in excess of its rating will void the manufacturer’s free warranty.

Unpacking
All items are contained in one
cardboard box.
Carefully unpack and check that
all items are included as in the
photograph.
Assembly
Attach the Disc Worktable using
two locking handles and washers.

Ensure the gap between the disc
and rear edge of the worktable is
a maximum of 1.6mm in order to
prevent finger trapping.
Using a set square ensure that
the table is at 90 degrees to the
sanding disc and lock in position.

If necessary, adjust the red index
pointer to align with the zero
degree mark on the angle scale
using a cross point screwdriver.
Loosen the belt angle locking
screw using a 5mm hex key and
raise the belt bed into a vertical
position.
Re-tighten the screw.
Locate the Belt Worktable onto
the circular slot in the belt bed.
Secure using the threaded knob
and washer.

Again, using a set square, adjust
the Worktable to 90 degrees to
the sanding belt and lock into
position.
Set the red index pointer to align
with the zero degree mark on the
angle scale.
Thread the open end of the Dust
Bag through the retaining clip and
attach to the dust port. The
tightness of the clamp can be
adjusted by turning the clamping
handle prior to locking it. Take
care not to over-tighten.
Alternatively the sander can be
connected to a suitable dust
extractor. In this case the filter
bag is removed and the extractor
hose connected directly to the
extractor port using an
appropriate adapter.

The port is 64mm/57mm
external/internal diameter.
Setting Up
Tracking the belt
Ensure the machine is disconnected
Slowly rotate the belt by hand by
turning the sanding disc, ensuring that
it is travelling in the direction of the
arrow.
Note if the belt is tending to slide off
the bed and to which side.
If the belt doesn’t slide sideways it is
already correctly tracked.
Viewed from the switch end, if the belt
moves sideways towards the disc:
Turn the tracking knob clockwise
(1/4 turn is usually sufficient).
If the belt moves sideways away from
the disc:
Turn the knob ant-clockwise.
Continue adjustments until the belt
remains central on the rollers.

Using The Sander
This sander is designed for use with wood and wood-based products only.
It should not be used for sanding metal and any such use would invalidate the warranty.
Sanding with the belt in the horizontal
position
The worktable must always be used
as a support when carrying out edge
or face sanding in the horizontal
position.
Move the workpiece across the belt
while keeping one edge against the
worktable.
Do not use excessive pressure and
take extra care when sanding thin
material.
Sanding internal curves
With care the idler drum end of the
sanding belt can be used for
smoothing & shaping the inside of
curved workpieces.
Never present the end of a workpiece
to the drum as this can cause it to
kick back.

Sanding with the belt in the
vertical position
Sometimes the sanding on the belt is
more convenient with it positioned
vertically –or any angle in between 0
& 90 degrees.
To adjust, loosen the locking screw
using a 5mm hex key. Position the
belt bed as required and then re-
tighten the screw.
Always use the worktable to support
the workpiece.
Sanding with the Disc
The disc sander is ideally suited to
smoothing end grain and fine-tuning
angled cuts with the aid of the mitre
guide.
Whenever possible use the front half
of the exposed disc as this will hold
the workpiece against the table.
If it is necessary to use the full width
of the disc, care must be taken to
hold the workpiece firmly as the rear
half will tend to cause it to lift.
Keep the workpiece moving to
achieve the best finish.

Maintenance
Replacing the Sanding Disc
Always ensure the machine is
disconnected from the power supply
before changing the sanding disc.
Remove the disc worktable and then
the disc cover which is secured with
six screws.
Carefully remove the existing self-
adhesive sanding disc with the aid of
a flat bladed scraper.
Remove any residue from the
sanding plate using mineral /
methylated spirit.
Peel the backing from the new
sanding disc and apply to the
sanding plate. Ensure that it is
positioned centrally on the plate, then
press firmly into place.
Re-fit the disc cover plate, tightening
all screws, re-attach the worktable.
A Velcro Conversion Backing Pad (VB300) can be attached to the plate in the same way as a
self-adhesive sanding disc. This enables Velcro backed sanding discs to be used which provide
easier changing without damage to the discs.

Replacing the Sanding Belt
Remove the belt worktable.
Position the belt horizontally by
loosening the hex head screw with a
5mm hex key.
Loosen this screw
Remove this screw
Release the tension on the sanding
belt by pulling out the tension lever.
Slide off the dust collecting cover
Loosen the two screws at the rear of
the belt which hold the bottom tray.
Slide and remove the tray.
It is now possible to remove the
sanding belt.
Locate the new belt over the two
rollers. Ensure that the arrow on the
inside of the belt corresponds to the
direction marked on the machine.
Replace the exhaust cover and
bottom tray, refitting/tightening all
screws. Re-tension the belt by
closing the tension lever.
Track the belt as in previous
instructions.
