Pre-Operation Inspection
WARNING
Before each use, inspect your threading machine
and correct any problems to reduce the risk of
serious injury from electric shock, crushing injuries
and other causes, and to help prevent threading
machine damage.
1. Make sure that the threading machine is unplugged
and the REV/OFF/FWD switch is in OFF position.
2. Clean any oil, grease or dirt from the threading
machine, including the handles and controls. This
aids inspection and helps prevent the machine or
control from slipping from your grip. Clean and main-
tain the machine per the maintenance instructions.
3. Inspect the threading machines for the following:
• Condition of the cords and plug for damage or
modification.
• Proper assembly, maintenance and completeness.
• Any broken, worn, missing, misaligned or binding
parts or other damage.
• Presence and operation of the foot switch. Confirm
that foot switch is attached, in good condition, that
it cycles smoothly and does not stick.
• Presence and readability of warning labels (Fi-
gures 1 & 2).
• Condition of the dies, cutter wheel and reamer cut-
ting edges. Dull or damaged cutting tools increase
required force, produce poor results and increase
the risk of injury.
• Any other condition which may prevent safe and
normal operation.
If any problems are found, do not use the threading
machine until the problems have been repaired.
4. Inspect and maintain any other equipment being
used per its instructions to make sure it is functioning
properly.
300 Compact/1233 Threading Machines
Machine and Work Area Set-Up
WARNING
Set up the Threading Machine and the work area
according to these procedures to reduce the risk of
injury from electric shock, machine tipping, entan-
glement, crushing and other causes, and to help pre-
vent threading machine damage.
Secure machine to stable stand or bench. Properly
support pipe. This will reduce the risk of falling
pipe, tipping and serious injury.
Do not use the Threading Machines without a prop-
erly operating foot switch. A foot switch provides
better control by letting you shut off the machine
motor by removing your foot.
1. Check work area for:
• Adequate lighting.
• Flammable liquids, vapors or dust that may ignite.
If present, do not work in area until source is iden-
tified, removed or corrected, and area is completely
ventilated. The threading machine is not explosion
proof and can cause sparks.
• Clear, level, stable, dry location for all equipment
and operator.
• Good ventilation. Do not use extensively in small,
enclosed areas.
• Properly grounded electrical outlet of the correct
voltage. Check the machine serial plate for required
voltage. A three-prong or GFCI outlet may not be
properly grounded. If in doubt, have outlet inspect-
ed by a licensed electrician.
2. Inspect the pipe to be threaded and associated fit-
tings. Determine the correct equipment for the job, see
specifications. Do not use to thread anything other
than straight stock. Do not thread pipe with fittings or
other attachments. This increases the risk of entan-
glement.
3. Transport equipment to work area. See Preparing
Machine for Transport for information.
4. Confirm equipment to be used has been properly
inspected and assembled.
5. Confirm that the REV/OFF/FWD switch is in the OFF
position.
6. Check that the correct dies are in the die head and
are properly set. If needed, install and/or adjust the
