6 Disassembly - Assembly
Disassembly: (see Spare Parts Drawing)
CAUTION
Prior to disassembly, disconnect equipment from air
supply in order to avoid the unintentional start of the
tool which may result in hand injuries!
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
Never clamp motor housing into a vice, without the usage of the
