3.3 Maintenance of the belt arm
Regularly empty the spark arrester (A) (see fig.: 3.3 ) to prevent hot sparks in
destroying or deforming the grinding belt and contact wheel. If the machine is
supplied with KU 12-exhaust unit regularly check if the suction channels need
cleaning. The dust bag is emptied or changed whenever necessary. The contact
wheel (B) should be replaced if the edges have been worn round or the lane is
defective. Change the graphite pad (C) on the grinding surface when necessary.
Fig.: 3.3
When changing the contact wheel the grinding belt (D) is removed as described
as above.
The nut (E) is unscrewed and the flange (F) is taken of together with the contact
wheel (B). The new contact wheel (B) is mounted in reverse order.
3.4 Operating the belt arm
Grinding on the belt arm can take place both at the contact wheel on the grinding
surface. It is also possible to dismount the grinding surface and grind on the
grinding belt alone. Lead the work piece slowly towards the grinding belt and avoid
uneven grinding. Always use a light but firm pressure to avoid destroying the
grinding belt and overloading the motor.
