operating Instructions

WARNING
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. Stop
the machine before wiping threads or screwing on fit-
tings. do not reach across the machine or pipe. To
prevent entanglement, crushing or striking injuries,
allow machine to come to a complete stop before
touching the pipe or machine chucks.
do not use this machine to make or break (tighten or
loosen) fittings. This can cause striking or crushing
injuries.
do not use a threading machine without a properly
operating foot switch. Never block a foot switch in
the oN position so that it does not control the
threading machine. A foot switch provides better
control by letting you shut off the machine motor by
removing your foot. If entanglement 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.

Follow operating instructions to reduce the risk of
injury from entanglement, striking, crushing and
other causes.
1. Make sure that machine and work area is properly set
up and that the work area is free of bystanders and
other distractions. The operator should be the only per-
son in the barricaded area while the machine is oper-
ated.
The cutter, reamer and die head should be up away
from the operator, do not place in the operating posi-
tion. Make sure they are stable and will not fall in the
work area.
Fully open the chucks of the threading machine. For
Manual Chuck machines, turn the front chuck hand-
wheel clockwise (see Figure 16). For Auto Chuck ma -
chines, move the REV/OFF/FOR (2/0/1) Switch to the
REV (2) position, depress and release the foot switch.
2. Insert pipe shorter than 2' (0,6 m) from the front of the
machine. Insert longer pipes through either end so that
the longer section extends out beyond the rear of
the threading machine. Confirm that pipe stands are
properly placed.
3. If needed, mark the pipe. Place pipe so that the area to
be cut or end to be reamed or threaded is approxi-
mately 4" (100 mm) from the front of the chuck. If
closer, the carriage may strike the machine during
threading and damage the machine.
4. Chuck the pipe.
For Manual Chuck machines: Turn the rear center-
ing device counterclockwise (viewed from rear of
machine) to close down onto pipe. Make sure that the
pipe is centered in the jaws. This improves pipe sup-
port and gives better results.
