Pressure Relief

SKIN INJECTION HAZARD

High-pressure fluid from dispense device, hose leaks, or
ruptured components will pierce skin. This may look like

you stop dispensing and before cleaning, checking, or
servicing equipment.

Relieve pressure in system by using two wrenches
working in opposite directions on pump element and
pump element fitting to only loosen fitting.

NOTE: When loosening pump element fitting, do NOT
loosen pump element. Loosening pump element will
change the output volume.
