Gap between the base of the main shaft pin and the drive pin
Setting the Solenoid (Continued)
With the arm timing set correctly, the roller switch needs to be adjusted back in to
the correct position. Before making any adjustment ensure that the machine is in
the
DIS-ARMED/SAFE
position. It is best to move the roller switch back in towards
the trap about 2-3mm (1/8") at a time. The motor needs to be stopping just as the
arm goes over centre, so that when the arm and motor have both stopped there is
a gap of about 3mm (1/8") between the main shaft drive pin (under the nylon
spring roller that the spring hooks to) and the 10mm Allen key bolt (that drives the
base of the main shaft). See diagram below.
