Structure and Function 6 6.3 Function The belt grinder consists of two functional groups: A grinding arm [1] with the grinding belt [4] and a polishing station [8] with polishing wheel [9]. The polishing station is mounted on the left and the grinding arm is mounted on the right of the housing. The switch [6] and the four machine bases [7] are fixed to the housing The specified direction of rotation for the polishing wheel [9] and the grinding belt is marked on the belt grinder.
Putting into operation 7 7. Putting into operation 7.1 Installing the belt grinder WARNING Risk of injuries in the event of slipping, falling or tilting belt grinder • Install the belt grinder on a stable table or other stand or substructure, which has sufficient stability to carry the weight of the belt grinder. • The stand must not be mobile or fitted with wheels or castors.
Putting into operation 7 The belt grinder is installed on the machine bases [1] on a slipproof, clean and flat surface. 7.3 Setting & adjusting the belt grinder CAUTION Risk of injuries due to rotating machine parts • Remove the plug from the socket before carrying out any adjustment work.
Putting into operation 7 The distance [2] between the deflection plate [1] and the polishing wheel [3] must not exceed 2 mm. 1 Undo the knurled nut [4], 2 Adjust the distance [2], 3 Tighten the knurled nut [4]. 7.4 Adjusting the belt alignment and running DAMAGE TO THE BELT GRINDER DUE TO SKEW STARTING UP OF THE GRINDING BELT! A misaligned, skew-running belt damages the housing. • Before switching on the belt grinder, check the running of the grinding belt, to ensure it is straight.
Putting into operation 7 1 Release the clamping lever [2] and undo the knurled lock nut [5] of the belt tensioner [3]. 2 Turn the grinding belt by hand and at the same time check whether it drifts to the side. 3 If necessary, use the knurled adjusting screw [4] so that the belt runs in the middle of the deflection pulley [1]. 4 Re-tighten the knurled lock nut [5]. 5 If necessary, readjust while the motor is running. 7.5 Adjusting and dismantling the water tank 2 1 3 4 Figure 7.
Putting into operation 7 Adjusting the water tank The quantity of water on the grinding belt is controlled by turning the eccentric [2]. 1 Turn the star handle of the eccentric so that the water tank swings upwards. The water level should just touch the belt and therefore wet the grinding belt with water. 2 After using the machine, swing the water tank [4] back downwards.
Putting into operation 7 7.7 Switching on the belt grinder WARNING Risk of injury due to damaged or incorrectly mounted machine parts Using the belt grinder with damaged electric parts or power cables can cause injuries due to electric shocks or malfunctions. Damaged grinding belts can be partly spun off the machine. • • Missing or damaged covers expose rotating parts and can cause injuries due to crushing and drawing in.
Putting into operation 7 CAUTION Risk of injuries on touching the belt grinder Touching the grinding belt or polishing wheel while the belt grinder is switched on causes injuries. • • • • Do not touch any abrasives while the belt grinder is switched on. Do not use any objects to brake rotating abrasives. The switched on belt grinder must be inaccessible to persons not working at the belt grinder, especially to children.
Putting into operation 7 Switch on the belt grinder as follows: 1 Insert the plug into the socket. 2 Check the belt running (see "Setting & adjusting the belt grinder" on page 17). 3 Adjust the water level (see "Adjusting the water tank" on page 20). 4 Press the green button (switch) at the switch. 5 Check the direction of rotation when starting up the belt grinder. - The direction of rotation is given by arrows on the covers. 7.

Servicing and maintenance 9 1 Remove and clean the water tank, 2 Undo the fastening screws and remove covers, 3 Remove residual abraded material from the machine, e.g. using a brush. 4 Re-attach covers and screw tight. 9.2 Changing the grinding belt Change the grinding belt if it has become blunt. (Interval: approx. 100 – 150 grinding operations). Replace the polishing wheel as follows: 1 2 Figure 9.
Servicing and maintenance 9 3 4 5 7 6 Figure 9.
Servicing and maintenance 9 9.3 Changing the polishing wheel The polishing wheel must be replaced if the distance between the deflection plate and polishing wheel can no longer be adjusted (see "Adjusting the deflector plate" on page 17). 1 2 3 4 5 Figure 9.
Servicing and maintenance 9 After finishing all repairs and servicing work, check that all dismantled parts have been completely and correctly installed, especially the covers. After changing a trial run must be carried out for 1 minute. In case of unusual behaviour, switch off the machine and correct the cause.
