Fig. 73 Inserting the belt disc into the V-belt.
Fig. 72 Install the five screw including washers for fas-
tening the attachment to the fan housing. Do not
tighten the screws firmly!
Fig. 75 Using the countersunk screws to tighten the bear-
ing unit of the sanding disc wheel.
Fig. 74 For simplified assembly, insert a screwdriver from
above through a hole in the attachment into a hole
in the bearing unit of the sanding disc wheel.
14 Pull the V-belt forward on the sanding disc wheel side. Make
sure that the V-belt is in the V-belt groove of the motor belt
pulley. The attachment can then no longer fall off the fan
housing.
15 To fasten the attachment to the fan housing, install the five
hexagon socket screws including the respective washers
(Fig. 72). Do not tighten the screws!
16 Push the attachment all the way back.
17 At the front of the attachment, insert the belt pulley of
the bearing unit of the sanding disc wheel into the V-belt
(Fig. 73).
18 To make sure that the hole pattern of the attachment and
the fixture of the sanding disc wheel line up properly, insert
a screwdriver from above through a hole in the attachment
into a hole in the fixture of the sanding disc wheel (Fig. 74).
19 Insert the bearing unit of the sanding disc wheel into the at-
tachment.
20 Screw the countersunk screws on the attachment into the
bearing unit of the sanding disc wheel (Fig. 75). Make sure
that the bearing unit is correctly seated in the attachment.
Then tighten the countersunk screws firmly.
21 Tighten the V-belt, as described in detail in Section 7.3 , by
pulling the attachment all the way forward until you feel a
slight resistance.
22 With 3 to 4 additional rotations of the belt-tensioning screw,
you will then tighten the belt exactly as required.
Do not tighten the V-belt too tightly since this will increase
the degree of wear and tear on the belt pulleys and V-belts
unnecessarily!
23 Tighten the five screws with which the attachment is fastened
to the fan housing carefully.
24 Place the UNICO down on its wheels again. Use a suitable
screwdriver to tighten the retaining screws of the bear unit
of the sanding disc wheel once more.
