1. Confirm that the equipment is properly set up.
2. Confirm that the pipe end is squarely cut and reamed/ -
deburred. Improperly prepared pipe can chip dies,
increase threading force and give improper threads.
3. Support pipe with pipe stands to prevent the pipe
and threading machine from tipping or falling. Place
the pipe stands in line with workholder. Longer pipe
may need multiple pipe stands. Only use pipe stands
designed for this purpose. Improper pipe supports
or supporting the pipe by hand can cause tipping or
entanglement injuries.
4. Carefully insert/center end of pipe in throat of the dies.
Turn workholder scroll to tighten jaws on pipe. The end
of the socket wrench can be inserted in the holes in the

scroll for tightening. Do not strike the scroll to tighten –
this can damage the scroll. Use the socket wrench to
tighten the clamp screw in the jaw. Make sure that the
pipe is secure to the geared thread er and is stable and
properly aligned (Figure 20) .

5. If using a 300 Power Drive, place 418 Oiler bucket
under the geared threader. If using 300A Power Drive
or a threading machine, route the flexible oil spout so
nozzle applies oil between chaser #1 and 2 (Figure
18) . Turn the oil spout valve to on position.
6. Set up guards or barricades to create a minimum of
one meter (three feet) of clearance around the equip-
ment and pipe. This helps to prevent non-operators
from accidentally contacting the machine or pipe and
causing tipping or becoming entangled in the rotating
parts.
7. Place the foot switch to allow a proper operating posi-
tion. With dry hands plug in the threading machine and
place the threading machine switch in FOR position.
8. Assume a proper operating position to help maintain
control of the machine and process (Figure 21) .
• Stand on the FOR/OFF/REV switch side of the
threading machine with access to the switch.
• Be sure that you can control the foot switch. Do not
step on foot switch yet.
• Be sure that you have good balance and do not
have to overreach.
