Inspections to be carried out:
Visual inspection
Concrete Crusher
• Opening width of the crusher arms at the tips (see chapter “Technical data”),
• General tightness (no leaks)
• Operability of the star grip,
• Handle present and secure,
• Labels complete and legible,
• Covers in perfect condition,
• Check of the torque of the pivot bolt (torque M
A
see “Technical Data”),
• Couplings must be easy to couple,
• Dust protection caps must be present.
• Dirt in the protective sleeve (this dirt must be removed immediately!)
• Check of the protective equipment on / around the recycling equipment, especially the
protective cover for the moving parts (this must be free of cracks!).
Crusher arms
• Crusher arms free of cracks and without any chipped spots or deformations on the cutting
surfaces,
• Cutting surfaces pass over each other without making contact,
• Bolts and retaining rings of the blade arms must be present and in correct working order,
• Tips must be present, clean and with an edge, without cracks.
9. Care and Maintenance
The equipment is subject to very high mechanical stresses. A visual inspection must be
carried out after every use: however, at least one visual inspection must be carried out every
six months. These inspections enable the early detection of wear and tear, which means that
breakages can be prevented by punctual replacement of these wearing parts. Also regularly
check the torque of the pivot bolt. (Torque M
A
see “Technical Data”)
Every 500 operating hours a crack test of the crusher arms is also essential. Therefore a
special crack testing kit is available.
Every 500 operating hours or if there is any doubt regarding the safety or reliability of the
equipment, a function test must also be performed. (Please also observe the relevant valid
national and international regulations pertaining to service intervals of recycling units).
CAUTION!
Clean the device before checking for contamination!
When cleaning the equipment, take care not to use any cleaning agent that has
a pH value outside the range 5 - 8!
WARNING / CAUTION!
To perform maintenance and repairs, workshop and personal safety equipment
appropriate for the work is an absolute requirement.
