2. Check the stator winding insulation resistance. If
the resistance is less than 1 megohm, call Graco
Customer Service for assistance.
3. With power disconnected, connect all the electrical
leads as indicated in the wiring diagram.
ELECTROCUTION HAZARD
Contact with electricity can be fatal! To
reduce risk of serious injury or death,
make sure the power supply lines to the
agitator are disconnected from the power supply
when servicing and repairing the equipment.
NOTE: The blade rotation should be clockwise, look-
ing down from the motor to the blade. To change the
direction of rotation, disconnect power from the agita-
tor power supply lines, and change the leads as indi-
cated in Fig. 3.
