sticking in open position when fluid pressure is
applied. Always have a 5/16 in. nut driver available to
quickly close manual valves on coupling block.
Do not exceed 1000 psi (7 MPa, 70 bar)
maximum fluid working pressure even in
static de-triggered conditions, or check
valve damage may result.
Follow when gun is out of service for any
length of time. Daily disassembly of gun for
cleaning is not recommended if it has been
operating properly. However, if you remove
the gun from the coupling block, flush and
clean thoroughly.
