TUBING & HANDPIECE MAINTENANCE INSTRUCTIONS
1. Empty abrasive from the tank before removing the tubing from the bottom fitting of the sand tank.
See illustration 2 for instructions on quick fittings.
2. Remove the handpiece assembly from inside the cabinet by pulling the tubing through the rubber
grommet.
3. Unscrew the nozzle cap
²
and remove the tip
±
and the sealing washer
°
.
Using a pair of pliers,
grasp the handpiece insert
¯
and with a twisting motion pull the tubing through the handle
®
. Try
not to damage the part with piliers. Pull the handpiece insert from the tubing by twisting and pulling.
NOTE: On some units, a steel barbed nozzle may be in the tubing - this should be removed from the
tubing and discarded it can no longer be used with the new long lasting polyurethane tubing. It may
be necessary to moisten the tubing and/or soak the tubing in warm water to ease onto the barb at
the bottom of the sand tank.
4. Using the new piece of tubing, push the tubing through the handle-using a twisting motion. When
the tubing is through the handle, pull in out several inches and press the handpiece insert
¯
all the
way onto the end of the tubing, until the tubing is flush with the front of the insert (see inset). It may be
necessary to moisten the tubing to ease the installation of the handpiece insert.
5. Pull the tubing back into the handle until the collar on the handpiece insert is butted-up to the end of
the handle. Pull the tubing through the rubber grommet and re-attach it to the jar assembly by pushing
it into the quick-release fitting. Re-assemble the sealing washer, tip and nozzle cap to the handle.
6. Blow out tank bottom fitting and press tubing back into the tank. Visually make sure the tube travels
past the black seal looking through the transparent raised area.
