8.  For each turn of the pipe, turn the cutting knife handle about 1/10 turn.  

Caution:

  Cut with moderate speed and force to avoid the distortion of the pipe and the damage of the 

cutting knife.

Inner Beveling 

1.  Turn the fore and rear chucks clockwise. Then loosen the three claws and install the pipe from behind the 

rear chuck, passing it through the fore chuck and past it by about 4 inches (100 mm). 

2.  Holding the pipe, turn the fore and rear chucks counterclockwise to secure the pipe then moderately 

tighten the hammer disk by turning it counterclockwise (Fig. 5). 

3.  Rotate the die head and cutting knife rack (Fig. 9) up out of the way then rotate the beveling rack (reamer, 

Fig. 10) in. 

4.  Move the gear shift to Fast (Fig. 7) and start the threader.  

5.  Rotate the sledge handle (Fig. 5) to move the beveling device (reamer) to the pipe then apply force to the 

handle to start beveling the pipe.

7.  Loosen the fore and rear chucks, by turning them clockwise, and remove the pipe from the rear chuck. 
 

 

After Each Use  

 

Unplug power when the machine is not in use.  

 

Clean the machine of metal scraps and excess oil. 

 

Coat corrosion resistant oil on working surfaces 

 

Store the pipe threader when it will not be used for a long time. Inspect the threader for good working 
condition prior to storage and again before re-use. Store it in a dry, secure place out of the reach of 
children. Please refer to Maintenance for more information.
