Note: Plug or cap the free end of tubing not being coned
or threaded to prevent cutiing oil from spilling onto the
ground.
5.16 Close the die head by pulling the two handles on the die
head trip yoke away from the motor.
5.17 Turn the machine on. Ensure the chasers are thoroughly
lubricated by the cutting oil.
5.18 Carefully slide the collet assembly with mounted tube
forward until the cone of the tube touches the chasers.
5.19 Squeeze the two handles on each side of the trip yoke
and collet assembly together to feed the tube into the
chasers until you see the threads being cut. Once all four
die chasers are cutting, let go of the handles and the die
head will self-feed.
5.20 When preset length has been threaded, the trip yoke is
actuated and will automatically open the die head.
5.21 Turn off the machine and clean the chips out of the die
head assembly to prevent damage when the yoke
assembly is pulled away from the die head. Pull collet
assembly away from die head.
5.22 Loosen the collet nuts and remove tube. Allow any oil
inside the tubing to drain back into the machine.
Note: The coning and threading machine is furnished
with a lubrication pump. This is used to supply cutting
fluid to the points of cone cutting and threading. A
sufficient supply of cutting fluid shall be maintained
during machining operations for successful coning and
threading.
Note: An optional thermostatically controlled immer-
sion heater is available for use in cold weather. Cutting
fluid should be Prestige 1246LV (AE Part No. P-8699) or
equivalent.
5.23 To Remove Chasers
5.23.1 Trip die head into open position.
If the die head is in the closed position, push on trip
yoke arms toward the motor causing head to trip into
open position.
5.23.2 Move die head to extreme open position.
You may have to start and stop the machine quickly
to get the die head to stop spinning in a good posi-
tion to have access to the head release lever.
CAUTION: Unplug the machine before proceeding.
Next, press head release lever in (located on adjusting
ring) with an implement, such as a screwdriver, to allow
the die head to spring back into extreme open position.
The die chaser slots are now fully exposed with the die
head in this position (Figure 8).
5.23.3 Remove chasers.
Place a clean cloth or pad against the bladed portion of
the chaser, then push the chaser outward until it pops
loose. Chaser spring plungers prevent chasers, before
removal, from falling into chips and oil.
Note : Chaser removal is done without removing the die
head from the machine.
Section 6.0
Assembly and Make Up of Coned Connection
After coning and threading operations, use Figure 12 and Table 4
for properly connecting and torquing coned connections.

Collar
Figure 12
Assembly and Make up of Connection
Step 1 Slip gland onto tubing as shown and thread collar on
tubing until one (1) to two (2) threads are exposed be-
tween collar and cone.
Step 2 Insert tubing into connection, engage gland and tighten
“finger-tight”.
Step 3 Tighten gland to specified torque.
