OEM Pins
Attachment or bucket pins are constructed of a different grade of steel
than OEM or Excavator pins. It is vital that the correct pins are used in the
appropriate places or excessive wear can occur.
Lock Out Switch
The Power-On/Power-Off switch for the attachment changeover sequence
must be have ‘lock-out’ capability, which prevents accidental deactivation
during the operation. This switch may be the standard fitment switch pre-
installed in the carrier machine, or a third party Lock-Out switch installed
with the coupler. Note that in some carrier machines this switch may be a
‘missile’ switch with a cover (see Fig. 8.0.1 for examples). For the purposes of
this manual we will call it the Lock Out switch, and it refers to the Power On/
Power Off in-cab switch that operates the coupler control system.
