Drive Handle
Removing and disassembling the drive handle
is a prerequisite to other procedures for
servicing the hour meter, drive switches, and
potentiometer.
1. Using a 14mm socket and extension,
unscrew the 5 screws (A) that secure the
drive handle to the machine.
• Make sure to support the handle as you
loosen the last screw.
• It is best to leave the screws and washers
in place, versus removing them. This
reduces the likelihood of dropping any
of them in the cavity below the solution
control.
2. Move the handle away, and disconnect the
harness connector (B).
3. Remove the 11 screws (C) that hold the two
halves of the handle together.
4. With the handle laying face-down, gently
separate the front and rear halves. There are
6 springs associated with the Go switches.
