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.


Features

As by the producer, the machine has the following features

  • pivoting aluminium table for disc and belt sander (up to 45°)
  • sanding belt unit tiltable from 0-90° horizontally and vertically
  • mitre fence for precise angle sanding
  • suction device
  • fast and easy belt change due to quick clamping device
  • suitable for longitudinal and front edges, round and mitre sanding and plane faces

The following is included in the delivery: 1 sanding belt, 1 sanding disc, mitre gauge, 2x ALU-table.

In the original version, the sanding disk is glued. After modification, it is possible to install velcro-backed abrrasive discs.

Refer to the manual to learn more about how you can change parameters or table-angles.

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!

Safety

Adhere to the following safety-rules

  • Always use the proper abrasive for your material, that is in perfect condition. Always change worn-of abrasives immediately! Never use a damaged abrasive! Only use abrasive that is allowed for this machine!
  • Never use the machine with defective or without mounted guard (HIGHEST RISK OF INJURY)
  • Never leave the machine running unattended! Before leaving the working area switch the machine off and wait until the machine stops.
  • Always disconnect the machine prior to any actions performed at the machine.
  • Avoid unintentional starting
  • Do not use the machine with damaged switch.

Maintenance

The machine does not require extensive maintenance. Service malfunctions and defects by trained persons only. Regular maintenance:

  • After each workshift: Remove chips and sanding dust from the device
  • After 10 hours of operation: Check all screw connections and tighten if necessary
  • Before first operation as well as later on every 100 operation hours you should lubricate all connecting parts.
  • Check regularly the condition of the security stickers. Replace them if required.
  • Check regularly the condition of the saw band and the saw band guide.
  • The good condition and perfect adjustment of the guiding rollers is essential for a smooth band guidance and a clean cut.
  • Store the machine in a closed, dry location

Refer to the manual in order learn more about the process to change the grinding belt and the disk.

Note: The installation of other than original spare parts voids the warranty!
