Section 5.0
Threading Operation
Install Collets and Die Chasers
5.1
Select the appropriate sized collet and die chasers using
Table #5 and tube size. Install collets as described in
Install Collet Section (steps 4.12 through 4.17)
5.2
Set the locks on the cart’s wheels.
5.3
Install die chasers in die head.
Note:
The die head has three positions; closed, open
and extreme open position.
When the die head is in the closed (cutting) position, the
die chasers are in position to cut threads.
In the open position, the die chasers are moved away
from the tubing. This is the position the die head should
be in when the threading operation is completed and
when adjusting thread depth.
In the extreme open position, the die chaser slots in the
die head are exposed permitting the dies to be installed
or removed.
Note:
Chasers are ground in matched sets of four (4) and
available in sets only.
5.3.1
Trip die head into open position.
With the die head in the closed position, push arms
mounted on trip yoke toward the motor causing
head to trip into open position.
5.3.2
Move die head to extreme open position.
5.3.3 You may have to start and stop the machine
quickly to get the die head to stop spinning in a good
position to have access to the head release lever.
Turn the machine off and unplug the power cord.
Next, press head release lever in (located on adjust-
ing ring) with an implement, such as a screwdriver,
to allow the die head to spring back into extreme
open position (Figure 8). The die chaser slots should
now be fully exposed with the die head in this position.
5.3.4
Insert chasers into die head slots.
The chasers and slots are each numbered 1 through
4. It is critical that the numbered chaser is placed
into the matching numbered slot.
For example, No. 1 chaser in No. 1 slot, No. 2 chaser in
No. 2 slot, etc.
