MACHINE PREPARATION
9. ASSEMBLING THE BRUSHES
1. Connect the power supply connector
2. Start up the motor and accelerate after a few minutes
3. Use the lever to lower the base until it lightly touches the floor (do not lower it completely)
4. Decelerate and turn the key to the OFF position (2) until the motor switches off, then
remove the key from the board
WARNING: carrying out the brush assembly operations with the power supply
connected may cause injuries to the hands.
5. loosen the knobs (1) shown in the figure
6. Remove the bases by pulling on them
7. Raise the bases with the aid of a tool that is suitable for both the weight (60kg) and the
type of hooks (see the special labels)
8. With the base up, insert the brushes in the plate housing beneath the base, turning them
until the three pins enter the niches in the plate itself; turn until the pin is pushed towards
the coupling spring and is locked into place. The photo shows the rotation direction to hook
up the right-hand brush; for the left-hand one, rotate in the opposite direction.
9. Reassemble the bases on the base support
10. Retighten the knobs
11. You are advised to invert the right and left-hand brushes every day. If the brushes are not
new however, and have deformed bristles, it is better to reassemble them in the same
position (the right-hand one on the right, and the left-hand one on the left), to prevent the
different inclination of the bristles producing an overload on the brush motor as well as
excessive vibrations.
