3.3 Maintenance of belt arm
Empty the spark arrester (A) regularly (see
fig.: 3.3
) to prevent warm sparks in
destroying or deforming grinding belts or contact wheel. If the machine is
equipped with a VFCB-exhaust system please control if the suction hoses need
cleaning. The dust bag must be emptied or changed whenever necessary. The
contact wheel (B) should be changed when the edges have been worn round or if
the lane is defective. Change the graphite pad (C) on the grinding surface when
needed.
Fig.: 3.3
When changing the contact wheel first dismount the grinding belt (D), as
described above.
The nut (E) is unscrewed and the flange (F) is taken off together with the contact
wheel (B). Mount the new contact wheel (B) in reverse order.
3.4 Operating the belt arm
Grinding on the belt arm can be done at the contact wheel or on the grinding
surface. It is also possible to dismount the grinding surface and grind freely on the
grinding belt. Lead the work piece slowly towards the grinding belt and avoid
uneven grinding to prevent destroying the grinding belt or overloading the motor.
