SCHEDULED MAINTENANCE
Section I. INTRODUCTION
4-1. PREVENTIVE MAINTENANCE.
Preventive maintenance is the responsibility of the
equipment operator.
Preventive maintenance should be conducted in accordance with this Manual and consist of inspecting,
servicing, and cleaning. Inspections will also reveal the need for repairs. Periodic Limited Technical
Inspections (LTI) will be required to ensure the torch kit is safe and serviceable. Regulator repairs should
only be performed by qualified technicians. Oxygen cylinder inspection and testing must only be conducted
by certified technicians.
Prior to conducting any maintenance, ensure proper shut down procedures are followed. Ensure
oxygen cylinder is shut off and all oxygen hoses are disconnected.
Always disconnect the torch and striker plate power cables from the battery when the torch is not in
use
.
Always use a clean, dry, oil-free cloth to wipe any part of the torch kit. Mild soap and water may be
used to wash components.
Never use compressed air to purge any part of the oxygen system as oil contamination may result.
Always use oxygen.
Always replace any worn or damaged parts with authorized replacement parts.
Always use Viton o-rings only.
a. After each use, wipe the torch assembly, striker plate assembly, battery, oxygen cylinder, and
regulator with a clean, dry, oil-free cloth.
b. Remove the collet nut, collet, collet washer, flash arrestor, and flash arrestor screen. Inspect for
damage and wear. Clean, replace as necessary, and reassemble.
c. Before and after each use, conduct a close inspection of the cables and hoses. Check for cuts,
burns, or any other sign of damage or wear. After every use, wipe down all cables and hoses with a
clean, oil-free cloth.
d. If the torch assembly has been used and/or transported underwater, dip the torch in fresh water
while depressing the valve lever to clean the exterior and flush the interior.
e. If any rods have been taken into salt water, rinse with fresh water and let dry before returning to
storage.
f.
If any rod igniters have been in salt water, rinse them with fresh water and dry before returning to
storage.
g. Any torch, rod or igniter which has become wet must be completely dry before being placed into
long term storage. Flush the interior with oxygen, argon, or nitrogen gas to displace residual
moisture.
