6. Before putting the machine into

operation The machine has to be set up where it can stand firmly, e.g. on a work bench, or it must be bolted to a strong stand. All the covers and safety devices have to be properly fitted before the machine is switched on. The sanding/grinding belt and sanding/grinding disk must be able to run freely. When working with wood that has been processed before, watch out for foreign bodies such as nails or screws etc. Before you actuate the On/Off switch, make sure that the sanding/grinding paper is correctly fitted and that the machine’s moving parts run smoothly. Before you connect the machine to the power supply, make sure the data on the rating plate is the same as that for your mains.

Fit the rubber feet (2) to the base (5). Fasten the plastic guard (16) using the screws (17) (Fig. 2). Mount the sanding/grinding disk (13) on the shaft (Fig. 3). Tighten the screw (18) with the socket-wrench (19) to fasten the sanding/grinding disk (13) (Fig. 3/4). Mount the bottom disk guard (20) using the screws (21) (Fig. 4). Mount the sanding/grinding table (14) and fasten using the screw (22) (Fig. 5). The sanding/grinding table (14) can be infinitely adjusted to any angle between 0° and 45° using the mitre scale (23) and the knurled screw (2). The adjustable cross stop (7) is for ensuring that the workpiece is guided properly. Caution! The sanding/grinding disk (13) must be able to run freely. However, the gap between the sanding/grinding table (14) and the sanding/grinding disk (13) must not exceed

Turn the sanding/grinding belt clamp to the right (9) to unclamp the sanding/grinding belt (11). Remove the sanding/grinding belt (11) by lifting out towards the back. Mount the new sanding/grinding belt by proceeding in reverse order. Caution! Check the running direction: On the casing (28) and on the inside of the sanding/grinding belt! 7.3. Adjust the sanding/grinding belt (11) (Fig. 1) Move the sanding/grinding belt (11) slowly by hand in the direction of running. The sanding/grinding belt (11) must run dead- center on the sanding/grinding section (6). If it does not do so, readjust it using the knurled screw (10). 7.4. Adjusting the sanding/grinding position of the sanding/grinding belt (11) (Fig. 10/11) Slacken the two nuts (29). Push the sanding/grinding belt (11) upwards to the desired position.
