ELECTRICAL INFORMATION
SPECIFICATIONS
In the United Kingdom, the ELECTRICITY AT WORK ACT 1989 requires all por table electrical
appliances, if used on business premises, to be tested by a qualified electrician, using a Portable
Appliance Tester (PAT), at least once a year. The HEALTH & SAFETY AT WORK ACT 1974
makes owners of electrical appliances responsible for the safe condition of the appliance and the
safety of its operator. If in any doubt about electrical safety, contact a qualified electrician.
ELECTRICAL SAFETY
• An RCCB (Residual Current Circuit Breaker) should be fitted in the mains electricity distribution
board. If the power supply is not protected by an RCCB, it is highly recommended that an RCD
(Residual Current Device) is used with all portable electrical products.
• Do not use any adaptor plugs.
• Do not carry or yank the tool by the cord/hose.
• Never expose power tools to rain or wet conditions as this will increase the risk of electric shock.
• Use an outdoor extension cord when operating a power tool outside.

POWER TOOLS
Your sander has been shipped assembled with the exception
of the sanding disc, disc guard, mitre gauge, sanding stop, and
worktable. Carefully remove all par ts from the box.
Do not discard the packaging until the parts have been
checked against the list in Fig.2 and the sander has been fully
assembled and tested to make sure it is working correctly.
Unless you need to move the sander regularly it is always best
to securely mount it on a workbench using hexagon bolts,
washers and locking nuts (not supplied) to fix it using the holes
in the base mounting flanges.
ASSEMBLY
WARNING Always ensure the sander is
unplugged before attempting assembly, installation
or changing parts or accessories.
1. Remove the disc guard as shown in Fig.3.
2. Remove the backing paper from the sanding disc (10) and
carefully place centrally on the sanding plate, aligning with
edges and making sure it is pressed firmly into place all
over, leaving no loose edges.
3. Replace the disc guard as shown in Fig. 3.
4. Fix the worktable (2) to the support arm (3) using the
Hex. bolts and washers (4). Attach the work table assembly
to the main body of the sander by (a) placing the spigot
of the support arm into the hole in the body and (b) screw
the fixing screw into the threaded hole next to it to secure
it at the required angle a shown in Fig.4.
5. Attach the sanding stop (6) to the rear of the machine using
the M8 Hex, head cap screws (7) as shown in Fig.5. Loosely

KOBE
INDUSTRIAL
POWER TOOLS
WARNING Some dust created by power sanding contains chemicals that may cause
cancer, birth defects or other harm. Some examples of these chemicals are: lead from lead-
based paint, and arsenic and chromium from chemically treated timber.
DUST EXTRACTION
Sanding operations are inherently dusty. To reduce the amount of dust pervading the air,
the sander has a dust extraction port which is 57mm (21/4”) in diameter which can easily be
connected to a dust collection system. It is strongly recommended that users employ a dust
collection system when using this sander.
Use of a mask or respirator is still required even
when a dust collection system is in use.
ON/OFF SWITCH
The ON/OFF switch is situated bottom right on the front of the
machine. The buttons are marked with international convention
being green for on and red for off. The green “ON” button is
recessed into the switch making it difficult to accidentally switch
the machine on, whereas the red “OFF” button stands out from
the switch making it easy to locate and press should emergency
require it.
NO VOLT RELEASE SWITCH
In the event of a power failure, the NO VOLT RELEASE SWITCH
automatically reverts to the OFF position. This eliminates
accidental start up of the machine when mains power is restored.
BELT SANDING – HORIZONTAL or VERTICAL
This sander can be used in vertical or horizontal mode.
To change the position of the belt sanding bed:
1. Using the Hexagon Key supplied, loosen the 6m cap screw
which clamps the drive mechanism as shown in Fig.17.
2. Raise the belt sanding bed as shown in Fig. 18.
3. With the belt sanding bed in the vertical position as shown
in Fig.19, tighten the cap screw in order to lock the bed in
place as shown in Fig 20.
Note: When sanding long workpieces, with the belt in the vertical
position, place the workpiece on the sanding stop and work
evenly across the belt. Fig. 21

KOBE
INDUSTRIAL
POWER TOOLS
BELT SANDING – HORIZONTAL
When sanding flat, broad sur faces on the belt sander, hold
the workpiece firmly but lightly onto the surface of the belt
and against the sanding stop, Fig.22 keeping fingers away
from the belt. Apply only enough pressure to remove material
from the workpiece. Too much pressure will cause undue
load on the machine’s motor, create heat on the bed and
shorten the lifeof the belt.
Note: Use extra caution when sanding very thin pieces and
when sanding long pieces, remove the sanding stop.
BELT SANDING – CURVED PIECES
When sanding inside curves on the belt sander, always sand
on the idler drum (right hand) end of the bed Fig.23. Hold the
workpiece firmly, keeping fingers away from the sanding belt.
Keep the curve pressed firmly against the idler drum, moving
the work evenly back and forth across the drum.
DISC SANDING – CURVED PIECES
When sanding outside curves on the disc sander, remove
the mitre gauge and work with the workpiece flat on the
table. The point of contact between the disc and the
workpiece should always be on the left hand side of the
disc so that it is in the downward motion, decreasing the
chance of wood splintering away from the main body of the
workpiece.
DISC SANDING – MITRED ANGLES
To sand mitred angles on the disc sander, set the mitre
gauge to the required angle (up to 60°to the left or right)
and tighten the locking knob as shown in Fig.24.
DISC SANDING – COMPOUND MITRES
A compound angle can be achieved by setting the angle
of the work table to the horizontal plane first (up to 45°to
the horizontal) and then setting the angle of the mitre gauge
(up to 60°to the left or right) to the disc as shown in Fig.25.
DISC SANDING – SMALL END GRAINS
Use of the sliding mitre gauge is recommended for sanding
small end grain surfaces on the sanding disc.
Note: Always move the workpiece across the sanding disc
from left to right holding the workpiece tightly onto the
surface of the work table.

WARNING Always ensure the sander is unplugged before attempting assembly,
installation or changing parts or accessories.
SANDING BELT
The belt will wear at different rates depending on the
type of material being sanded and the pressure being
applied to the workpiece.
1. Slide the tensioner to the right to release belt tension
as in Fig. 6.
2. Remove the worn belt from the drive mechanism as
shown in Fig. 7, taking note of the direction of travel
of the belt (towards the left hand end of the machine
denoted by the dust extraction port).
3. Place the new belt in position over the drums as
shown in Fig.8, with the edge of the belt aligned with
the rear of the drums then release the tensioner to
grip the belt.
4. Before using, check the tracking as described in
“Belt Tracking“ and adjust as necessar y.
BELT TRACKING
The belt-tracking adjustment is set at the factory so that
the abrasive belt will run true on the drums. If however,
the belt should track to one side or the other, an
adjustment can be made by turning the tracking knob,
which is located on the top right hand side of the front of
the machine Fig. 9. Turn the knob clockwise to make the
belt track onto the back of the machine or anti clockwise
to track towards the front of the machine.
WARNING Be careful if turning anti
clockwise as this could make the belt
track off the side of the machine and
possibly cause personal injury.
To properly track the sanding belt:
1. Plug in the sander.
2. Turn the power switch on and then off, taking note of
whether the belt moves in its track to one side or the
other or stays with it’s edge against the rear of the
drums.
3. If it does not move then the tracking is set correctly.
4. If the belt moves towards the front of the machine,
turn the tracking knob clockwise a 1/4turn.
5. Turn the power switch on and then off again, taking
note of any belt movement.
6. Readjust the tracking knob another 1/4turn, as
necessary.
