3A VCWS14 CONTROL BOX REMOVAL AND INSTALLATION
If the control box needs to be returned for repair, it must first be removed from the table. It
is also advisable to remove the microswitch and send it along with the control box to the
Valpar plant. Refer to part 3B for instructions for removing the microswitch. On models made
prior to 1985 there are two mounting screws, which go through the control box and into the
table. On models made 1985 and later, there are four mounting screws on the lip of the control
box. Unplug the work sample from the wall outlet. Pull out the plug in the back of the control
box. Remove the mounting screws and the control box will come off the table. Reverse these
steps to remount the control box after it has been repaired.
3B MICROSWITCH REMOVAL AND INSTALLATION
The microswitch is located under the table about one inch behind the control box. Unplug
the control box from the wall outlet. Disconnect the microswitch by loosening the terminal
screws that connect the wires to the switch. Remove the two Phillips head mounting screws
from the table. The microswitch should come loose. Remove the two machine screws that hold
the microswitch to the angle bracket.
Reverse the above steps to remount the microswitch to the table. Mount the microswitch to
the angle bracket. Be sure the roller (small microswitch wheel) is to the left when the angle
faces toward the front. On the VCWS14 manufactured prior to 1985, three wires will need to
be connected to the microswitch. For units manufactured after 1985, only two wires are
connected. On both models the red wire connects to the common terminal and the white wire
connects to the normally open terminal. On the earlier models the black wire will connect to the
normally closed terminal.
3C MOTOR REMOVAL AND INSTALLATION
Unplug the VCWS14 from the wall outlet. When removing the motor, first remove the
microswitch so it will not be damaged. Refer to part 3B for removal instructions. Turn the
work sample upside down on a table or on the floor.
