5. Assembling the machine
5.1
Armature
5.1.1
Place the cover plate (120) onto the armature shaft.
5.1.2
Press on the ball bearing (450).
5.1.3
Press on the packing ring (130).
5.1.4
Press the grooved ball bearing (50) on the
commutator side on.
5.2
Motor housing
5.2.1
Insert the pre-assembled armature (100) into the
intermediate bearing (200).
5.2.2
Insert the pole housing (490) into the motor housing
(90).
5.2.3
Place the air conducting ring (110) in the motor
housing (90). (Pay attention to the position).
5.2.4
Insert the pre-assembled intermediate bearing with
armature into the motor housing and screw on.
Insert the sliding switch (480).
5.2.5
Assemble the brush holder assembly (60) with
carbon brushes (70) and connect.
Warning: The brush holder assembly is supplied
with the carbon brushes pre-assembled.
After mounting the new brush holder assembly, the
carbon brush latch on the side must be released by
slightly bending up (Fig. 1).
The carbon brush can now move freely and is
positioned on the commutator. The latch should only
be released when the armature is mounted.
When releasing the latch ensure that the guideway
of the carbon brush is not bent.
Then check that the carbon brush can be moved
easily. If only the carbon brush is to be changed the
latch on the carbon holder does not need to be
released.
5.2.6
Pre-mount the cable (580) to the strain relief (30)
(conduct the cable and protective hose through the
cover beforehand).
5.2.7
Connect switch (540) to the electronics module (40)
and screw on the mains cable (580) according to the
connection diagram. Pay attention to the bolster
