clean cloth. If the valve stem is bent, or the seating
surface is nicked or marred, replace it with a new
assembly (09M24).
3. The sealing 'O'-ring located in the front end of the
handle, behind the attaching nut, may require re-
newal periodically. Remove it by catching it with a
scriber, orastiffwire hook, and pull it out. Squeeze
a new ring (P/N 85W64) into the head, and then
pushitevenlyintothe recess behind the locking nut
with a blunt instrument.
4. Each torch tip is equipped with a filter-screw, which
holds a mixer disk in place. If flow of gas through
the tip appears to be restricted, remove the filter-
screw with a 1/8-in. socket key ('Allen wrench') and
replace both filter-screw and mixer disk.
PRECAUTIONS & SAFE PRACTICES
A. DO NOT let acetylene or LP-Gas escape near
any possible source of ignition. Accumulations
of either in certain proportions may explode if
ignited.
B. NEVER store acetylene or LP-Gas tanks (cylin-
ders) in a closed or confined space, such as a
closet, tool box, or automobile trunk.
C. NEVER solder a container that contains or has
contained flammable liquids or vapors (includ-
ing gasoline, benzene, solvents, and other simi-
larmaterials) unlessthe container has been thor-
oughly purged of all traces of flammable mate-
rial and vapors.
D. Before starting work always test for leaks
around all joints with a soapy water solution.
E. NEVERuse a flameto test forleaks of flammable
gases.
F. NEVER use a tank with a leaking valve.
G. DO NOT attempt any repairs to an acetylene or
LPGastank,except totighten the packing-gland
nut on the valve.
H. NO NOT abuse or drop tanks or handle them
roughly.
I. NEVER use a tank as a roller or support.
J. NEVER use a hammer, wrench, or pliers on a
tank valve equippedwith a handwheel. Onsmall
acetylene tanks, always use PREST-O-LITE
valve wrench (box type, P/N 505L00).
K. DO NOT open tank valve more than 1-1/2 turns.
(Preferably no more than 3/4 of a turn.)
L. Leave valve wrench on tank valve stem so that
tank valve can be closed quickly in caseof emer-
gency.
M. NEVER allow full tank pressure to enter the
hose. Always use a regulator when there is a
needle valve on the torch handle.
N. NEVER lay a torch down unless the gas flow
has been shut off. If you want to maintain a
pilot flame when you stop work for short inter-
vals, provide a rack or stand for the torch, away
from combustible materials. Do not leave it
unattended unless you are sure there is no dan-
ger of it being disturbed by unauthorized per-
sons.
O. Examine your hose for leaks frequently. Dip-
ping it in a bucket of clean water, with the pres-
surein the hose,is the quickest andeasiest way.
P. DO NOT use hose that is worn, or any equip-
ment that is in need of repairs.
Q. Do NOT start fires. Be very careful when work-
ing near combustible material.
R. Fuel gas tanks (cylinders) are equipped with
fusible-metal safetydevices. NEVER store tanks
near radiators, furnaces, or other heat sources.
