Holzmann BT 203_914

After being commissioned, this machine will sit in the metal workshop, next to the grinding stones on a wooden box containing the manual and the accessories.

It is a combined disc and belt sander with a 200mm rough sanding disc and a 914x100mm belt sander. Both are always simultaneously driven by the 550W motor. Belt speed is 9,5m/s and disc speed is 2850 min-1.

This type of machine is helpful for all sanding tasks that require a fixed angle. Both sander sides have adjustable sanding tables and a slot for a miter gauge to guide your workpiece in a defined agle against the sanding disc or belt.

Materials

As by the makers specification, the machine is permitted to process wood, and wood-like materials.

Use the disc sander for rough shaping, or to create outside curves. Use the belt sander to sand your the wood/ material.

Should you use it to process other materials or light metals, such as Aluminium, adhere to the special precautions mentioned in the machine introduction, and make sure that the mounted sanding belt/ disk supports your material.

Proper Use

Always check the following before you start to work with the machine

All cables and plugs
Loose screws and connections. Damaged parts have to be replaced immediately, no operation of the machine in the meantime!
Tight fit of table and safety fence
The free and centered run of sanding belt and disc
Attention! To prevent ﬁngers from being squeezed between the band and table a minimum separation of 2 mm has to be maintained between the table and grinding band. Check that this is the case.

Configure the machine for your use case (table-angles etc).

The angle stop can be used for angles of up to 45°, to the left or right, by releasing the locking button and adjusting the angle stop to the desired angle.
The backing plate of the grinding belt has to be adjusted so it almost touches the grinding belt. In order to adjust it, release the two screws holding the plate in the machine rack. Tighten the screws again after you adjusted the plate.
To remove the plate to perform special jobs (e.g. polishing or contour-grinding), loosen the two attachment screws

To turn the machine on, press "I" (green). Turn the machine off, press "O" (red).

When working with the machine, do not apply too much pressure to the sanding abrasive.

As the machine offers no possibility to clamp your material, it is important, that complete work piece maintains a firm grip on the worktable!
