Flushing
• Flush out old fluid with new fluid, or flush out old
fluid with a compatible solvent, such as toluene,
naptha, or mineral spirits before introducing new
fluid.
• Use lowest possible pressure when flushing.
• To flush entire system, circulate through gun fluid
manifold (with manifold removed from gun).
• Always leave hydraulic oil or a non-water based,
non-water absorbent fluid in system. Do not use
water.

Flush equipment only in a well-ventilated area. Do not
spray flammable fluids. Do not turn on heaters while
flushing with flammable solvents.
Only use flush solvents that are compatible with Fluo-
roelastomer seals. Non-compatible solvents will dam-
age seals and cause hazardous conditions, such as
high pressure leaks and pressure switch failure.
