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 carton.
Carefully unpack and check that all the
items are present.
Assembly
Place the sander on a flat surface.
Use a 14mm spanner to adjust the
supporting leg so that the belt bed is
horizontal.
To do this you might need to loosen the
hex
head bolt which clamps the bed in
position.

The table can be fitted in either of two
positions, depending upon whether you
are using the sanding disc or the sanding
belt.
To attach the table when using the
sanding disc:
Locate the table bracket into the curved
slot next to the disc.
Fix in place using the clamping screw &
washer provided.
Adjust the angle of the table using a set
square so that it is at right angles to the
disc.
Ensure that the gap between table & disc
is no more than 1.6mm. This will prevent
fingers from becoming trapped when
sanding.
Tighten the clamping screw.
Use a cross head screwdriver to adjust
the red pointer to ‘0’ degrees against the
scale.
Pointer
Locking screw

The sanding belt can be used in the
vertical or horizontal position - or any
angle in between.
When using the belt sander, either the
back stop or the sanding table must be
fitted.
The back stop is attached using the two
socket head screws and washers
provided.
Adjust the stop so that there is a
maximum gap of 1.6mm to the belt.
To adjust the angle of the sanding belt:
Loosen the hex socket clamping bolt
Lift the sanding belt into the vertical
position.
Re-tighten the bolt.
Remove the back stop.
Fit the sanding table in the same manner
as when using it with the sanding disc.
Secure using the clamping screw/washer.

Adjust the table so that it is at 90 degrees
to the belt.
Ensure a maximum gap of 1.6mm.
Adjust the red pointer so that it indicates
‘0’ degrees against the scale.
Pointer
Locking screw
The mitre guide is fitted to the slot in the
table.
It can be adjusted to any angle in a 120
degree range.
It is used to guide the work piece and
give an accurate angle.

It is advisable to use dust extraction when
using your sander. There are separate
extraction ports for the belt and disc with
an outside diameter of 37mm.
An appropriate adapter may be required.

Setting Up
Tracking the belt
Ensure the machine is disconnected from
the power supply.
Slowly rotate the belt by hand in the
direction shown.
If the belt is moves off to one side it
requires a tracking adjustment.
If the belt stays central 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 anti-clockwise.
Continue adjustments until the belt
remains central on the rollers.
Tracking knob.

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.
The machine should be placed on a firm level surface before use.
Sanding with the belt in the horizontal
position
The work table or back stop 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 stop.
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 sanding on the belt is more
convenient when it is positioned vertically
–or at any angle in between 0 & 90
degrees.
To adjust, loosen the locking screw using
the 5mm hex key. Position the belt bed
as required and then re-tighten the
screw.
Always use the work table or back stop 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 down 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 off the table.
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 work table and then the
disc cover which is secured with four
screws.
Carefully remove the existing self-
adhesive sanding disc using 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 and tighten both
screws. Re-attach the work table.
The sanding disc can be converted to use the Hook & loop type discs.
A conversion backing pad (VB150) can be attached to the plate, then allowing Velcro-backed sanding
discs to be used. The great advantage of this system is that discs can be swapped in seconds and discs
can be remounted multiple times, allowing the user to work through different grits to achieve the desired
finish.

Replacing the Sanding Belt
Remove the bed support bolt using a
14mm spanner.
Remove the work table or tool rest if
fitted.
Loosen the two screws indicated and
slide off the drum dust cover.
Release the tension on the sanding belt
by pulling out the tension lever.
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 drum dust cover and bottom
tray, refitting/tightening all screws.
Re-tension the belt by closing the lever.
Track the belt.
Re-fit the bed support bolt and re-attach
the work/table or tool rest as required.
The life of the belts and discs can be greatly extended by regular cleaning with the BC01 Abrasive Disc &
Belt Cleaner which will remove any build-up of sawdust and resin.
