Fluid Tip
The fluid tip may be removed either with the tur-
bine in place, or the turbine off the unit. “Fluid Tip
Removal” figure shows removing the tip with the
turbine in place.
This allows removal and replacement of the fluid
tip while the applicator is on line.
Fluid Tip Removal
Replacement
Ensure the tip openings are fully open and
clean. Apply an O-ring lubricant to the O-ring
to help hold it in place on the fluid tip. Insert
the O-ring into the undercut groove on the
tip. Place the tip on the tool and tighten in a
counter-clockwise direction into the fluid tube.
Do not over-tighten. There will be a small gap
between the flange of the fluid tip and the fluid
tube (see “Fluid Tip/Tube Gap” figure). Ensure
the O-ring is properly positioned when complete.
Tighten to 25-30 lbs•in (2.83-3.4 Nm) torque.
