Mounting gearbox on motor:
First the motor shaft (2), the bore of the clamping
hub (5) and, if present, the sleeve (6) must be
degreased. Then insert the sleeve into the
clamping hub until the stop is reached. The
clamping hub (5) must be positioned so that the
clamping screw (7) can be tightened via the
access hole. The cover plate (8) is removed for this
purpose. The motor shaft (2) is guided (centered)
into the clamping hub (5) until the motor flange
(3) makes contact with the adapter plate (1).
Ensure that the motor shaft does not jam in the
clamping hub. The fixing holes on the motor
flange and adapter plate must match precisely.
The motor is mounted on the gearbox with four
appropriate mounting screws (4), with a screw-in
depth into the adapter plate of 15 to 25 mm.
Tighten clamping screw (7) to 115 Nm with torque
wrench, socket wrench extension and hex socket
insert (WAF 10). If necessary, block the output
shaft (9). Close off the access hole again with
cover plate (8).
