Keep the sander in motion while the drum is working or marks will appear which are very difficult to remove with further sanding. Always work from left to right. Fig. 27 In order to obtain satisfactory sanding, the sander should be passed over the surface several times with different sizes of sanding grain. Passes New floors Old floors first grit 30-35 grit 24 second grit 60 grit 36-40 third grit 100 grit 60 fourth We recommend that the sander be passed over the surface at least three times if the floor is new. If the floor in question has already been varnished we recommend that the sander be passed four times, according to the following chart: grit 100 – 10 – MAINTENANCE Changing and Adjusting the Belt It is important to check the tension of the Poly - V belt and change it if necessary. Loosen the screw to adjust or change the belt and then tighten it. The belt must not be too tight or too loose. Remember that an over-tight belt makes it difficult to start the motor and that the drum will turn freely if they are too loose (fig. 28). Fig. 28 Sanding Drum Maintenance Check that the drum surface is in good condition and that there is no sawdust inside it, as this could throw it off balance (fig. 29). Clean the sanding drum from time to time, using air to clean out the drum chamber. Fig. 29 Maintenance of the Wheels Check the wheels periodically (fig. 30). • Make sure that the surfaces do not have glue or debris stuck to them. • Change them when worn. • Clean the bearings with air. Fig. 30 Prevention Maintenance In order to avoid inconvenient setbacks, we suggest that you carry the following along with your normal tools: • a Poly - V belt. • a dust bag. • a set of capacitors. In this way you will be sure that your machine will always function. – 11 – TROUBLESHOOTING • Below we offer a series of suggestions which Chances are that the machine will have sucked will enable you to resolve some of the most in a nail, a piece of wood or any other foreign frequent problems which arise when sanding body which will have blocked the blades of the wooden floors. fan.
