Remove the locking device from the assembly head.
Move the assembly head into position as high and as far back as
possible and lock it again.
Now turn the assembly tower backwards.
Wheel rims with asymmetric drop-centres should be positioned so
that the narrow bead seat is facing up.
In order to prevent damage to alloy wheels when clamping, it is
recommended to only clamp these from the outside and to use
plastic protectors.
Gently press down the gear change pedal to set the required wheel
rim size (e.g. for a 20" wheel rim, set the clamping claws to 21").
Release the pedal as soon as this has been set.
The pedal is now in the first rest position.
Position the wheel so the clamping claws only touch the tyre.
Press the wheel rim down until the rim flange touches the clamping
claws.
For hard tyres, the assembly arm can be used on the blank holder
with a cone adapter.
