Outrigger Proximity Switch (Version 2)
On newer versions of the 800D, the OMS and RCL use
proximity switches to determine if the outriggers are fully
extended. The switches are located between the operator’s
cab and A-frame outriggers. The proximity switch (1,
Figure 2-7) uses a tab (2) on the outrigger arm to determine
when the outrigger is fully extended.
