numbers over the die head slot. Fully insert the die
with the numbered side up.
6. Pull out the cam plate knobs and rotate cam plate to
correct size for the application as marked on the die
head. Release knobs to lock in place.
7. Replace the stop screw in the selector plate.
Set-Up and Operation
WARNING
Always wear eye protection. Wear steel toe foot -
wear to help protect from tipping tools and falling
pipe.
Do not wear gloves or loose clothing. Keep sleeves
and jackets buttoned. Loose clothing can become
entangled in rotating parts and cause crushing and
striking injuries.
Keep hands away from rotating pipe and parts. Do
not reach across the machine or pipe. To prevent
entanglement, crushing or striking injuries, allow
equipment to come to a complete stop before touch-
ing.
Properly secure the geared threaders to the thread-
ing machine/power drive and pipe. Improperly se -
cured tools can slip and fall and cause striking and
crushing injuries.
Do not use a power drive or threading machine
without a properly operating foot switch. Never
block a foot switch in the "ON" position. A foot
switch provides better control by letting you shut off
the machine motor by removing your foot. If entan-
glement should occur and power is maintained to
the motor, you will be pulled into the machine. This
machine has high torque and can cause clothing to
bind around your arm or other body parts with
enough force to crush or break bones or cause
striking or other injuries.
One person must control both the work process
and the foot switch. Do not operate with more than
one person. In case of entanglement, the operator
must be in control of the foot switch.
Set up and operate the geared threader according to
these procedures to reduce the risk of injury from
machine tipping, entanglement, crushing, striking
and other causes, and to help prevent equipment
damage.
Geared threaders can be used a variety of ways, with the
primary difference being whether the pipe is stationary or
turns during threading.
Model 141/161 Receding Geared Threaders
If the pipe is held stationary (such as in a pipe vise), the die
head end of the geared threader rotates around the pipe
during threading. Threading can be done by hand with a
D-1440 ratchet or by using an 840A Universal Driveshaft
and a threading machine. Use of the 840A driveshaft is
often referred to as "rear mount".
Alternately, geared threaders with the proper accessories
can be driven by a variety of threading machines. In
these cases, the die head end of the geared threader is
stationary and the workholder and pipe rotate. This method
is often referred to as "front mount" or "close coupled".
Stationary Pipe Set-Up
1. Locate a work area that has:
• Adequate lighting.
• Clear level, stable, dry location for all of the equip-
ment and the operator.
2. Clean the work area before setting up any equip-
ment. Wipe up any oils or liquids.
3. Inspect the pipe to be threaded and associated fittings
and confirm that the 141 or 161 Geared Threader is a
correct tool for the job. See the Specifications.
4. Confirm that equipment to be used has been properly
inspected.
5. Make sure that pipe to be threaded is solidly mount-
ed and stable. Pipe and mounting must be able to
withstand the weight of the geared threader and the
force and torque required for threading without mov-
ing or turning. When using a pipe vise, make sure that
it is properly sized and secured to prevent tipping
during use. Tristands must be bolted to the floor. For
longer lengths of pipe, use appropriate pipe stands to
support extra length.
6. If using with 840A Universal driveshaft, the centerline
of the pipe must be at same level as the centerline of
threading machine spindle.
7. Confirm that the pipe end is squarely cut and reamed/ -
de burred. Improperly prepared pipe can chip dies,
increase threading force and give improper threads.
8. Properly adjust the geared threader for the work to be
done. Make sure that the die head is correctly backed
off to make an appropriate sized thread. See "Ad -
justing Geared Threaders".
9. Use appropriate equipment to lift the geared thread-
er and place over the end of the pipe orienting one jaw
