6.4 INSTALL A COLLET IN THE MODEL 301QL
1. Select the proper size Collet for the outside diameter of the tube or pipe to be
squared. The size of the Collet is determined by the outside diameter of the
tube or pipe to be squared.
2. Do not drop the Collet.
3. Remove the Ball Lock Pin from the Collet Clamping Assy of the Model 301QL
by pulling it straight out.
4. Be sure that the Toggle Clamp Lever is in the up position to allow the pin to be
pulled out.
5. Swing the Clamping Head Assy upward to allow the Collet slide into place.
6. Insert the Collet into the tapered Collet Clamping Model 301QL.
7. Swing the Collet Clamping Assy down into position.
8. Insert the Ball Lock Pin completely into the hole provided for it in the Collet
Clamping Assy.
9. Be sure that the Toggle Clamp Lever is in the up position in order to permit
the pin to be pushed into the Collet Clamping Assy.
10. Insert the pipe or tube to be machined into the Collet.
11. Verify a clearance of 1/16” (1.6 mm) between the Tool Bits(s) and the pipe or
tube face as held by the Collet.
12. As the Collet closes, the tube is drawn toward the Tool bit. Do not let the Tool
Bit touch the pipe or tube at this time. To do so will cause damage to the Tool
Bit or the Tube Squaring Machine when power is applied.
13. Lock the tube or pipe in position by pushing the Toggle Clamp Lever all of the
way down.
14. Attach the power supply to the Model 301QL and pull the Trigger to start the
