You have purchased a quality industrial product that is designed for high performance
and long service life. If correct use, safety and maintenance procedures are observed
this machine will last for many years.
SAFETY INSTRUCTIONS
KOBE INDUSTRIAL POWER TOOLS have been specifically designed to help you work SAFELY
and EFFICIENTLY. Your care and good judgement are the best protection against injury, but always ensure
that the appropriate safety equipment is worn. All possible hazards cannot be covered here, but the most
important ones have been highlighted.
PERSONAL PROTECTION
Always wear eye protection that complies with a recognised standard (CSA or ANSI).
Wear a mask or respirator when dust is generated.
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 lumber. To reduce exposure to these chemicals, work in a well-ventilated area;
use approved safety equipment; and use dust masks that are specially designed to filter out
microscopic particles.
Keep bystanders out of the work area while operating the tool.
ALERTNESS
Always stay alert, watch what you are doing and use common sense when operating this tool.
Never operate the sander when tired or under the influence of alcohol or prescription/non-prescription
drugs.
Do not wear loose clothing or jewellery. Keep hair tied back.
ELECTROCUTION
Always keep dry. Do not use in rain, snow or near water.
Always place the Sander on a non conductive surface.
Always switch the power off prior to plugging in the tool.
Grounded tools must be plugged into an outlet that has been properly installed and grounded in
accordance with all local legislation. Never remove the grounding prong from the plug or modify it in any
way. Do not use adaptor plugs. If in doubt as to whether the outlet is properly grounded, consult a
qualified electrician.
Never touch with wet hands.

THE ENVIRONMENT
Always dispose of unwanted tools, accessories and packaging materials in an environmentally
friendly manner.
A comprehensive repair and
service facility is available
through your local Kobe agent for
all your electric tools.
This sander requires little
maintenance other than clean or
vacuum dust any from around the
motor housing, extraction port
and other sander parts.
Dress sanding surfaces and replace discs/belts as required - a worn belt or disc leads to inefficiency and
extra wear on the machine due to increased pressure required to do the job.

UNPACKING
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 necessary.
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.

OPERATING INSTRUCTIONS
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

POWER TOOLS
OPERATING INSTRUCTIONS
BELT SANDING – HORIZONTAL
When sanding flat, broad surfaces 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 life
of 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.
