Safety unloader valve
Safety unloader valve (4) († Fig. 2) is not
serviceable. Replace if malfunction is
apparent. Upon reassembly, tighten to
10 ft-lbf (13,5 Nm).
Safety unloader valve (4) is set to open at
3 750 to 4 250 psi (259 to 293 bar) lubricant
pressure. If pressure switch fails to operate
and shut off hydraulic supply to pump, safety
unloader will open at approximately
4 000 psi (275 bar) to relieve lubricant
supply line pressure (safety unloader is
preset and not adjustable).
WARNING
Do not operate without safety unloader.
Safety unloader ships with pump
assembly, but is not pre-installed.
Safety unloader must be installed
before using pump.
Failure to comply may result in death
or serious personal injury.
WARNING
Do not plug outlet of safety unloader.
Plugging safety unloader outlet will
result in pressure build up.
Failure to comply may result in death
or serious personal injury.
