methods is the responsibility of the system designer
and/or installer. Before any installation is attempted, care-
ful evaluation of the specific service environment, includ-
ing chemical environment and service temperature should
be completed.

Pre-Operation Inspection

WARNING
Before each use, inspect your geared threader and
correct any problems to reduce the risk of serious
injury from electrical shock, crushing injuries and
other causes and prevent machine damage.
1. If the geared threader is attached to a threading
machine or a power drive, make sure the equipment
is unplugged and the directional switch is set to OFF
position.
2. Clean any oil, grease or dirt from the geared thread-
er, including the handles and controls. This aids
inspec tion and helps prevent the tool or control from
slipping from your grip. If necessary, clean the work -
holder jaws with a wire brush. Remove metal shavings
and chips from the die head.
3. Inspect the geared threaders for the following items:
• Proper assembly and completeness.
• Broken, damaged, missing, misarranged or binding
parts.
• Presence and readability of warning label (see Fi -
gures 1 and 2) .
• Any other condition that may prevent the safe and
normal operation .
If any problems are found, do not use the geared
threader until the problems have been repaired.
4. Inspect the cutting edges of dies for deformation,
chips or other issues. Dull or damaged cutting tools
increase the amount of force required, produce poor
quality threads and increase the risk of injury.
5. If necessary, lubricate the geared threader per the
maintenance instructions. Wipe any excess lubricant
from the equipment.

6. Inspect and maintain any other equipment being
used per its instructions to make sure it is functioning
properly.
If using a threading machine or power drive, make
sure that the foot switch is attached to the machine
and that it and the cord are in good condition. Press
the foot switch pedal and confirm that it cycles
smoothly and does not stick.
Do not use threading machines or power drives that
do not function properly.

Adjusting the Geared Threaders

procedures to reduce the risk of injury and to help
