Unscrew the hand grip and pull back the protective sleeve as shown in the illustration below.
Remove contamination and swarf from the mechanical section of the unit (as shown in the
illustration below) and blow out carefully with compressed air.
If the sections of the protective sleeve that seal against the crusher arms are clearly worn or
torn, you should replace the entire sleeve.
10.2.3 Main checks
The mechanical transmission elements on the device are subject to very high mechanical
loading and must therefore be checked at least every 500 operating hours. These inspections
enable the early detection of wear and tear, which means that breakages can be prevented
by punctual replacement of these wearing parts.
Parts that are undamaged can be reassembled after careful greasing with LUKAS special
grease.
Parts showing slight wear (scuff marks) can be repaired by polishing and can be refitted after
greasing as required.
More severe signs of wear require replacement of the damaged parts (in pairs).
After these intervals a crack test of the crusher arms is also essential. Therefore a special
crack testing kit is available.
Clean the outside of the device from time to time and wipe it with oil to prevent corrosion.
