May have affected dust counts in OSB labs when stopped and when restarted(?)  

Found that the pitch actuator ram operates normally when decoupled from the fan variable pitch/vane assemblies (toggling power with 4-20ma signal removed resets position counter and causes ram to fully retract.  Re-landing 4-20ma signal wires, once reset, allows remote control of ram position).  

The exhaust variable pitch/vane assembly is easy to manually stroke through its range when mechanically decoupled from the actuation system but the intake variable pitch/vane assembly feels dry and has excessive friction.  It is quite difficult to stroke through its range even whilst decoupled from the actuator/crank/exhaust vane.  I had to use a heavy sledge hammer and "tap" with authority to get it to stroke and to change pitch -> For now, I manually left the pitch at reduced flow from the "as found" state then re-coupled everything but I did not re-energize the actuator ram.  As such, no remote pitch adjustment can be made.  The mechanical force needed to stroke the front pitch/vane assembly is too much for the 500lb max. force of the actuator ram.  Also, SF06 is "viby" when compared to SF05.
