Section 9 CLUTCH ASSEMBLY
Clutch Position Switch ................................................ Fig 9.81
9.8 ...... Clutch Position Switch
The clutch position switch controls the feed so that only one sheet
at a time is numbered. It is adjusted as shown in Fig. 9.81.
Using a 5.5mm wrench or spanner, loosen the two micro switch
fixing screws and move the switch up or down so that the tip of the
stop collar operates the micro switch 2 to 3mm (3/32” to 1/8”)
before the end of the lever.
The clutch must be operated and the machine turned by hand to
check this adjustment. You will hear a "click" as the switch
operates, or, if this is not possible, a meter may be used between
the common and one of the other terminals on the switch.
Note ....... Before using a meter, switch the power off at the mains
and set the meter to read resistance (
