After each use:
Clean the surface with an air blaster or medium
bristle brush to remove any remaining abrasive material.
Changing ceramic nozzles:
Periodically (depending on the amount of grit accu-
mulated in the nozzle and the amount of use), the ceramic
nozzle will become worn, causing the spray to become
irregular or to stop.
1.
Disconnect the sandblaster from the air supply.
2.
Remove the nozzle tip (A) and carefully pull out the ceramic nozzle (B) .
3.
Gently insert the new ceramic nozzle, being careful not to dislodge the internal tooth washer (C).
4.
Replace the nozzle tip (A).
NOTE: For replacement ceramic nozzles, contact Coleman® Powermate® at the number on the back of this
manual
Changing orifices:
Occasionally (after approximately 6-8 nozzle replacements), the nozzle orifice will need to be replaced.
1.
Disconnect the sandblaster from the air supply.
2.
Loosen the allen socket screw (D) from the tool with the hex key wrench (included).
3.
Remove the nozzle assembly (E).
4.
Remove the orifice (F). NOTE: If the orifice is stuck, tap the nozzle assembly lightly until the orifice is
dislodged.
5.
Place a new washer (G) on the new orifice (F).
6.
Gently drop the new orifice into the nozzle assembly.
7.
Reassemble the nozzle assembly and tighten the allen socket screw.
This sandblaster kit comes with standard 1/8", 3/32" and 5/64" orifices.
