Assembly

1. Belt Table

Gently ease the table into place with the belt support entering the slot in the table.
Screw the Table Locking Lever into place, ensuring a flat washer is used on the levers’ threads noting that the locking lever has a LEFT HAND thread, i.e. turn anticlockwise to tighten.

2. Disk Table

Slide the table pegs (Fig 2) into the slots in the Upper Disk Cover (Fig. 3) to the extent that the
Locking Levers can be screwed in as shown in Fig. 4, ensuring flat washers are used on the locking lever threads
With the table secured, position the
Disk Cover/Dust Extraction Port asshown, with the locating pin on the cover ‘A’, engaged in the slot in the hinged cover ‘B’.
Secure with four screws (arrowed)

3. Feet

The four feet may be very gently eased into the holes at the base of the machine.
Alternatively, the machine may be mounted on a workbench or a wooden base, using the four holes in the base as mounting holes. In order to maintain complete stability when in use, the wooden base should be secured to a workbench using ‘G’ clamps.

Important Adjustments – Before Use

Belt Table Adjustment
With the belt correctly tensioned (see Maintenance), adjust the Belt Support so that it is square and bears very lightly on the back of the Sanding Belt. Ensure the two hex socket head securing screws (arrowed) are tight. A hex. socket wrench is provided.
Slacken the Table Locking Lever and position the table so that a gap of 1.5 – 2 mm exists between the slot in the table and the belt, then lightly secure the table using the locking lever.
Place an engineers square on the table so that it butts up against the belt, then unlock the adjuster by unscrewing the locknut at 7B. Screw the adjuster 7A, clockwise or anticlockwise whilst bearing down on the table at a point adjacent to screw 7A, until the square indicates that the table is at right angles.
Lock the adjuster, ensuring the nut is tight, then, maintaining pressure on the table, finally secure the table using the locking lever. by turning anticlockwise.
Finally, check to ensure the gap between the table and belt is between 1.5 – 2 mm.
It is possible to set the table to any angle up to 45 degrees, simply by slackening the locking lever and positioning the table using a protractor or angle setter, then retightening the locking lever.

2. Disk Table Adjustment

Place an engineers square on the table and slacken the locking levers slightly.
Adjust the table so it is at right angles to the Disc, using the square, then tighten the locking levers.
If necessary, adjust the pointer, adjacentto the angle indicator beneath the table, (B Fig.4), so that it registers zero
Slacken the upper disc cover securing 8
It is possible to set the table to any angle up to 45 degrees, simply by slackening the locking lever and positioning the table using a protractor or angle setter, then retightening the locking lever. screws (A Fig.4) using the wrench supplied, and adjust so that a gap of 2-3mm exists between the disc and table, and the table is square. Tighten the securing screws.
It is possible to set the table to any angle up to 45 degrees, simply by slackening the locking levers and positioning the table using the angle indicator, then retightening the locking levers. If the angle is critical, a protractor or angle setter should be used.
If required, slide the Quadrant into its groove in the table

NOTE: The quadrant may be used to hold a workpiece at any desired angle for sanding that angle with accuracy

Operation

IMPORTANT!
Ensure that ALL components are secure, ALL correct adjustments have been carried out, and ALL safety precautions have been observed BEFORE plugging the machine into the mains supply, and switching ON.

Attach a vacuum cleaner or other dust extraction device to the relevant extraction port (depending upon the medium to be used), and switch it ON.
Switch the machine ON by pressing the Green ON button.
If using the belt, check to ensure it is tracking properly…adjust if necessary.
Holding the workpiece firmly, place it on the table and gently slide it into contact with the belt or disk. DO NOT force it, a light force only is necessary.

IMPORTANT!

When using the sanding disk, ALWAYS use the left half of the disk ONLY, i.e. that , side where the direction of rotation of the disk is down towards the table.

Maintenance

IMPORTANT!
Whenever making adjustments or carrying out maintenance tasks, ALWAYS switch OFF the machine and disconnect from the power supply

1. Changing the Sanding Belt

1.1 Remove the belt table completely by unscrewing and removing the table locking lever.
1.2 Remove the two side cover securing screws (9A), followed by the upper roller pivot screw (9B), then pull off the side cove

1.5 Turn the belt by hand and observe how it moves on the rollers, indicated by its position on the support. This will determine whether not it is tracking correctly. If it moves sideways, turn the adjuster – 10C, so that it stabilises over the middle of the support.
At this point the belt is tracking properly. The belt is tensisioned automatically and cannot be adjusted

1.3 Turn Adjuster (10C) anticlockwise sufficiently for the sanding belt to be slipped off the rollers.
1.4 Replace the sanding belt ensuring it is central about the rollers, and the arrow (10D) is pointing down towards he table.
1.5 Turn the belt by hand and observe how it moves on the rollers, indicated by its position on the support. This will determine whether not it is tracking correctly. If it moves sideways, turn the adjuster – 10C, so that it stabilises over the middle of the support.
At this point the belt is tracking properly. The belt is tensisioned automatically and cannot be adjusted.
NOTE: Turning the adjuster clockwise will cause the belt to move one way…turning it anticlockwise and it will have the opposite effect.

2. Changing the Disk

2.1 Remove the disk table and lower cover/dust extraction port (see fig.5)
2.2 Slacken the two screws securing the upper disk cover and slide it backwards.
2.3 Using a sharp instrument, tease off a portion of the sanding disk, sufficient for it to be grasped by hand and peeled off.
Remove all residual adhesive, and finally clean the disk with a solvent.
2.4 Peel the backing from the replacement sanding disk and fix to the disk ensuring it is centralised. Press it firmly to ensure it is secure.
2.5 Replace the table and lower disk cover, and adjust gap between table and disk, by positioning abd securing the upper disk cover.
