3 Remove parts that hinder motor replacement. These parts include the vacuum
pump, duct, and the belt.
4 Remove the motor, then remove the pulley from the motor.
5 Mount the pulley on the new motor, then set the motor and vacuum pump on
the base. The bolts that secure the pulley, motor, and vacuum pump should be
tightened finger-tight at this time.
Final tightening should be completed after adjusting the pulley deviation and
the distance between the vacuum pump pulley and motor pulley (distance noted
at step 2). The pulley deviation should be 0.3 mm or less.

6 Adjust the tension of the new belt. If the belt tension is outside the prescribed
range, move the motor position in 0.1 mm increments to adjust length "L".
7 Reassemble the remaining parts in the reverse order of the disassembly proce-
dure, then connect the wire connectors.

6.9 Vacuum Hoses
Procedure
1 Remove all 16 nozzle holders.
2 Move the placing head whose vacuum hose is to be replaced to ST9 at 180°, and
then replace the vacuum hose.
3 Connect the vacuum hose to manifold position 4 as shown in the figure below.
WARNING
• Press EMERGENCY STOP before performing this procedure.
• Spring recoil may cause the cam to rotate suddenly if not at its
origin position (0°). Working inside the machine is dangerous
and requires special care.
