Lift the microswitch off
of the posts.
Remove the 3 screws
securing the gearbox/
motor assembly to the
chassis. Note: two of the
three screws may thread
into a nut.
Unplug the motor and
lift the gearbox/motor
assembly from the
chassis.
*If the motor wires are
attached to the circuit
board and can only be
unplugged from the
bottom of the motor,
mark which color wire
goes to each terminal
to prevent the burr from
spinning the wrong way
after reassembly (it
should spin clockwise).

Remove the on/off
switch nut by using
pliers.
Remove the PCB from
the chassis by removing
the two lower mounting
screws. Let it dangle
to the side, or unplug it
entirely.
Remove the screw which
mounts the switch to
the chassis. The switch
should come free easily.
The on/off switch ports
are labeled on the back
of the switch. Transfer 1
connection at a time to
avoid confusion. A wiring
diagram is at the end of
this guide for reference.
The wires are secured
in the switch by push-
grip connectors. Insert
a paperclip or straight
pick into a port on the old
switch, which will loosen
the connector’s grip
on the wire and allow
removal. Locate the
correct port on the new
switch and push the wire
in to insert.

sure to plug the power
cord into the connector.
