1.  Ensure that the governor control line from the 

reservoir is located at or near the top of the 
reservoir. (This line, if located near the bottom of 
the reservoir, can become blocked or restricted 
by the reservoir contents e.g. water or ice.)

Park vehicle, chock 

wheels, and follow all standard safety procedures. 
Remove the governor and install a 

fi

unloader port.  Add a section of air hose (min 
1 ft long for a 1/2" diameter line) and a gauge 
to the

compressor.  Shut off the air supply and observe 
the gauge.  A steady reading indicates no leakage 
at the unloader port, but a falling reading shows 
that the unloader mechanism is leaking and needs 
to be serviced.
