Originally supplied with glued-on disc, a Velcro backing has now been fitted to make discs more easily changeable (coarse grit ->> finer grits).

The Velcro-attachment makes the sanding action slightly 'softer' - see, for example discussion on woodworking forum sites.

There is a thin metal disc to use as a separator in the drawers cabinet under the Belt/Disc sander. To use this and change the sanding disc:

1. Unplug the sander from the mains.
2. Remove the yellow disc guard.
3. Separate the sanding disc backing from the machine half of the Velcro at the top of the disc, being careful not to tear the machine Velcro away from the machine.
4. Gradually work the separator into the gap, while rotating the disc assembly by hand until the entire disc comes away.

To fit a new sanding disc:

1. Place the separator plate against the machine Velcro.
2. Place a sanding disc against the plate and align it with the machine disc.
3. Move the separator slightly away so that the Velcro starts to grip.
4. Slowly remove the separator completely, massaging the two halves of the Velcro together.
5. Make sure that the sanding disc is flat and centred correctly before replacing the yellow guard.

Maintenance: The Velcro backing is made from the widest strip size, 6", available at the time. A replacement 12" disc is available from Martins Supplies, see this page.

Supplied with glued-on disc. A stock of replacement discs in various grits exists, together with some for Velcro attachment should we change to that in future.

Drive belt is easily changed: there is a single posi screw on back that holds on a cover plate. The drive belt is "142XL037" (e.g. from ebay bearing suppliers).

See BDS150 manual

Which gives details of how to tension the drive belt, and lubricate the machine.

Belt and Disc Cleaning

Silverline 224688 Sanding Belt Cleaning Block

As abrasive discs and belts are is used they fill up with waste material. To remove this, apply the belt/disc cleaning block to the surface of the abrasive, and 'sand away' the accumulated waste. This restores the abrasive's original colour, and greatly extends it life.

Do not allow discs and belts to get clogged up - this reduces the abrasives effectiveness, and they, and the workpiece overheat, and it takes more effort to achieve the results you want.

Belt Cleaner: Toolstation Item 37031(deadlink April 2019) / Silverline 224688 or 218490 .

Dust Extraction and Safety

All of the sanders in the dusty area are connected to the large green extractor. This is switched on at a central location. Please remember to switch it off when the job is done as this saves electricity.

Remember that breathing dust can be hazardous to health. Wear a dust mask when using these tools. You may also find ear defenders useful as the ShopVac is rather noisy in operation!

Clean Up Afterwards!

Even with vacuum extraction, using these machines still creates a lot of dust. Always brush / vacuum away after use so as to leave the equipment ready for the next person.
