Your sander has been shipped assembled with the exception of the sanding disc, disc guard, mitre gauge, sanding stop, and worktable. Carefully remove all parts 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.
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.

OPERATING INSTRUCTIONS
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 leadbased 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. Fig. 17 Use of a mask or respirator is still required even when a dust collection system is in use.
OPERATING INSTRUCTIONS
BELT SANDING –
HORIZONTAL
Note: Use extra caution when sanding very thin pieces and when sanding long pieces, remove the sanding stop.
ON/OFF SWITCH
BELT SANDING –
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.
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 – Fig. 18
Fig. 22
CURVED PIECES
CURVED PIECES
Fig. 23
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.
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 –
Fig. 21
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.
HORIZONTAL or VERTICAL
DISC SANDING –
This sander can be used in vertical or horizontal mode.
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.
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.
DISC SANDING –
2. Raise the belt sanding bed as shown in Fig. 18.
Fig. 24
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.
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
DISC SANDING –
SMALL END GRAINS
Use of the sliding mitre gauge is recommended for sanding small end grain surfaces on the sanding disc.
Fig. 20
Note: Always move the workpiece across the sanding disc from left to right holding the workpiece tightly onto the surface of the work table.
