Disassembly - Assembly
Disassembly: (see Spare Parts Drawing)
Prior to disassembly, disconnect equipment from air
supply! Only experienced maintenance personnel may
assemble or disassemble this equipment.
After repair or maintenance, verify that equipment runs to specification!
Principally, use only DEPRAG original spare parts. Otherwise, a reduction
in equipment power-output and an increased maintenance-requirement
occurs. If NON-DEPRAG parts are installed, DEPRAG is justified to void
any existing warranty and liability obligations.
Attention:
Motor- and gearing parts may be damaged if dropped!
Attention:
Never clamp motor housing into a vice, without the usage of the
protective chucking jaws, since damage to motor-housing and
internal parts is unavoidable.
