Connect the mains lead to a standard, 230 volt (50Hz) electrical supply through a
fused good quality 13 amp BS 1363 plug, or a suitable fused isolator switch.

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in the mains lead are coloured in accordance with the
following code:

Green & Yellow - Earth

Blue - Neutral

Brown - Live

As the colours of the flexible cord of this appliance may not correspond with the

ASSEMBLY

1. Assemble the stand in the manner shown in Fig.2.
The four top panels are secured with a single bolt,
with flat washer, in each corner, and the legs are
then bolted on, followed by the leg braces.

Do not tighten the nuts until all bolts are in place
and the stand is rocked vigorously to ensure it is
stable. When satisfied, tighten securely.

Fig.2

2. WITH ASSISTANCE, considering its
weight, raise the machine and
place it on top of the
stand.
Manoeuvre it so that the
bolt holes, viewed from
below, line up. Enter the
M6 screws fitted with flat and
lock washers and tighten securely.

3. Screw the Belt Tensioning Lever (see Fig.4) securely into its housing.

NOTE:
Except for the table, your Sander is now fully assembled. The location of the Table will depend
upon the job in hand, i.e. either adjacent to the disc or the belt. Table fitting and adjustments
are described on pages 8 and 9.

The machine is fitted with a Sanding Disc and Sanding Belt at the factory.

CHECKS BEFORE USE

As with all machinery, it is important to ensure that the various components are properly
secure and in good order before use.

The machine is designed so that when switched ON, both the belt AND the disc will rotate.
It is also important therefore, to ensure that the belt runs true on the rollers, referred to as
‘Tracking’. Although the necessary adjustments have been carried out at the factory, it is
nevertheless prudent to perform this check when first setting up your machine, in the event
it has been disturbed during transit.

Belt Tracking Check

The rollers must run parallel, otherwise the
belt will be driven off to one side. To
perform the check, ideally the belt
should be in the vertical position, as this
position provides greater safety for the
operator.

To raise the belt to its vertical position,
slacken off the two securing screws, one
of which is shown in Fig. 3, the other is
diametrically opposed. Then raise the
arm, and retighten the two screws.

- 7 -

Fig. 3

With the belt raised, ensure that nothing can interfere
with the disc or belt, and that the Belt Tensioning Lever
(1, Fig.4), is pushed fully to the rear - in the direction
of the arrow.

Plug in to the mains supply and press the GREEN ON
button, marked ‘I’ to start the machine. keeping well
away from the belt.

Observe the belt as it passes over the front (top)

roller....there should be no creep to one side. If it does

creep, switch OFF by pressing the RED OFF button,
marked ‘O’.

Adjacent to the belt tensioning lever, is the Roller
Adjustment Knob (2, Fig.4). Slacken the locknut as
shown in fig. 4 and back the nut off a turn or two.

Restart the machine, and screw the Adjuster Knob
very gently in or out to compensate for the creep.
When the belt is running true, switch OFF and tighten
the locknut, ensuring you do not allow the adjuster knob to turn. When satisfied, restart and
check. If necessary, repeat until the belt runs true.

Fig. 4

FITTING THE TABLE

A ...to the Disc

The Table is mounted on a Support Bar (6, Fig.1 and 1, Fig.5). ‘Flats’ are milled at each end
of the bar. Insert the end with the shorter length flat into the housing on the machine.

NOTE: It may be necessary to unscrew the two securing screws (2,Fig.5) in order for the bar
to be inserted fully.

Tighten the securing screws.

Fig. 5

Slide the table assembly on to the
support bar, and bring the table to within
2mm of the disc, then tighten the two
securing screws (1, Fig.6).

To ensure the table is at exactly 90o to
the disc, place a small engineers square
on the table and bring up to the disc.
Slacken off the Table Angle Adjustment
Knob, shown in Fig.5, and adjust
accordingly so that the table is true.

Tighten the adjustment knob, and if
necessary, zero the pointer, adjacent to
the scale, by slackening the securing
screw and repositioning.

- 8 -

B...to the Belt

Before attempting to attach the table to
the belt mounting, raise the belt arm and
secure with the two securing screws, as
explained under ‘Checks Before Use’, p7.

Slide the Table Support bar into the
mounting as shown in fig. 6 with the shorter
flat on the end of the bar - inwards. Tighten
the two securing screws.

Mount the table on the support bar, bring
to within 2mm of the belt and tighten the
securing screws (1, fig 6).

To ensure the table is square, proceed
as previously described for squaring the
table to the disc.

When using the table with the sanding
belt, remove the work stop from the belt
by removing the two securing bolts as
shown in fig. 7.

Ensure the screws are replaced and
tightened before use. The lower screw
also secures the Lower Belt Guard. Ensure
this is properly in place when tightening.
Ensure also, the flat washer is used with
the upper bolt.

ENSURE the work stop is relaced correctly

- see Using the Belt on page 10.

METHODS OF USE

WARNING! Always observe the proper safety precautions before use.
Remember, failure to observe these precautions could be extremely
hazardous.

A. Using the Disc

Check to ensure the table is no more
than 2mm from the disc, before switching
ON.

Hold the work firmly, as shown in fig. 8 and
ALWAYS hold the workpiece against the
left half of the disc. i.e. that half moving
downwards towards the table.

DO NOT exert too much pressure. A light
touch is all that is required.

- 9 -

Fig. 8

Fig. 8A shows the table being used in

conjunction with the Mitre Gauge.

Set the gauge to the angle you require
and hold the workpiece firmly against
the gauge, feeding it gently into the
disc.

Keep the workpiece in contact with the
left side of the disc as far as possible.

Fig. 8B shows the table set to an angle.
The mitre gauge may also be used with
this setup.

Angles up to 45o may be set.

If accuracy is required, check angle
using a suitable square or template.

Fig. 8A

Fig. 8B

B. Using the Belt

The Work Stop must be in place when
using the belt horizontally.

Bolt on as shown in Fig.9, ensuring the
flat washer is used between the inner
face of the fence and the body on the
upper bolt.

The lower bolt also secures the lower
blade guard.

When tightening the bolts, ensure a
gap of no more than 2mm exists
between the belt and the work stop,
as indicated.

The belt is used for long pieces, as shown
in Fig. 9A. The workpiece is held firmly
against the work stop.

DO NOT exert too much pressure - a light
touch is all that is required.

...or the belt used in the vertical position

as shown in Fig.9B.

NOTE: The work stop has been removed.

Fig. 9B

DUST EXTRACTION

Provision is made for forced dust
extraction on both the disc AND belt.
The dust extraction outlets are shown in
Fig.10 and have an outside diameter
of 56mm (21/4”).

Connect a suitable hose to a vacuum
cleaner via a reducer, or Dust Extraction
device (see your Clarke dealer).

MAINTENANCE

CAUTION: Before carrying out any maintenance or servicing, ALWAYS ensure the
plug is disconnected from the mains supply.

A. Changing the Belt

1. Raise the table and secure in the vertical position.

2. Remove the lower Belt Cover, by

slackening the four securing screws
sufficiently for the cover to be
slipped off.

3. Remove the screw securing the dust

hand (or rear) mounting.

4. Slide the Belt Tension Lever fully

FORWARD. (As the Belt Arm is vertical,
this would be - UPWARDS).

The belt may now be slipped off and
replaced by a new one.

5. Tension the belt by sliding the tensioning lever backwards (downwards), then replace

the belt cover.

6. Proceed to check belt tracking, as described on page 7

B. Changing the Disc

Fig. 11

Fig. 12

1 Remove the disc side cover as shown

in Fig. 12, then peel off the disc.

2. Clean any excess adhesive from the

face of the disc, if any, and replace
with a new disc, ensuring it is firmly
attached.

3. When satisfied, replace cover.
