injury from injection, splashing fluid, or electric
shock, follow the Pressure Relief Procedure in your
separate gun instruction manual before installing this
kit or repairing the gun.
WARNING
Fire, Explosion, and Electric Shock

To reduce the risk of fire, explosion, or elec-
tric shock, never operate the gun with a
