403 TORCH HANDLE

Part No. 02X93

!

CAUTION

These INSTRUCTIONS are for experienced operations. If you are not fully familiar with the principles of operation and safe practices for air-fuel gas equipment, we urge you to read our booklet "Precautions and Safe Practices,"

From 2035. Do NOT permit untrained persons to operate this equipment. Do NOT attempt to operate this equipment until you have read and fully understand these INSTRUCTIONS. If you do not fully understand these INSTRUC-

TIONS, contact your supplier for further information.

This sheet covers use of PREST-O-LITE tips which attach directly to the 403 handle. Supplementary instructions are supplied with SWIRLJET air-fuel gas (F-

15-132), SWIRLJET air-acetylene tips (F-15-132), and with leak detectors (F9372).

REGULATOR

TEST FOR LEAKS

CONNECTING:

1. Attach a regulator to your acetylene or fuel gas tank, follow the instructions supplied with the regulator.

2. Connect a 3/16-in. hose assembly with 'A'-size lefthand-thread fittings to the regulator outlet and to the handle. Tighten the connection nuts with a wrench.

3. Then insert the tip into the locking nut at the front of the handle. Holding tip in position, tighten the locking nut by hand to lock the tip in place.

TEST FOR LEAKS:

Close the shutoff valve on the 403 handle. Open the tank valve, set the regulator to deliver 10 psi (see instructions supplied with regulator) and check for leaks, using a thick solution of soap and water, at the points indicated on the adjoining sketch.

LIGHTING & FLAME ADJUSTMENT:

1. If you have set the regulator to 10 psi delivery pressure for testing, you may wish to reset it before lighting the flame, since only a few tips require a pressure that high. Unless you are sure 10 psi is needed, we suggest the regulator be reset for 5 psi before you light your torch.

NOTE: When using SWIRLJET tips, be sure to follow the pressure recommendations given in the instruction sheets supplied with those tips.

2. Having set or reset your regulator to 5 psi delivery pressure, open the needle valve on the 403 handle, and light the gas at the tip with a friction lighter.

3. After lighting the torch, adjust the flame size, if necessary, by changing the setting of the regulator pressure-adjusting screw or partially closing the torch

SHUTTING OFF:

1. For short intervals, merely close the needle valve on the torch handle.

2. For longer periods, or if you are going to leave the outfit unattended, close the tank valve as well as the torch valve.

MAINTENANCE

1. If the needle valve turns too freely, or there is gas leakage around the valve stem, tighten the valve stem packing nut. If leakage persists, replace the valve stem assembly (P/N 09M24).

2. If the needle valve does not shut off completely, remove the valve stem assembly and wipe the seating surfaces on the stem and in the body with a

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 renewal periodically. Remove it by catching it with a scriber, or a stiff wire hook, and pull it out. Squeeze a new ring (P/N 85W64) into the head, and then push it evenly into the 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 filterscrew with a 1/8-in. socket key ('Allen wrench') and replace both filter-screw and mixer disk.

B. NEVER store acetylene or LP-Gas tanks (cylinders) 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 (including gasoline, benzene, solvents, and other similar materials) unless the container has been thoroughly purged of all traces of flammable material and vapors.

D. Before starting work always test for leaks around all joints with a soapy water solution.

E. NEVER use a flame to test for leaks of flammable gases.

F. NEVER use a tank with a leaking valve.

G. DO NOT attempt any repairs to an acetylene or

LP Gas tank, except to tighten 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 equipped with a handwheel. On small 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 case of emergency.

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 intervals, provide a rack or stand for the torch, away from combustible materials. Do not leave it unattended unless you are sure there is no danger of it being disturbed by unauthorized persons.

O. Examine your hose for leaks frequently. Dipping it in a bucket of clean water, with the pressure in the hose, is the quickest and easiest way.

P. DO NOT use hose that is worn, or any equipment that is in need of repairs.

Q. Do NOT start fires. Be very careful when working near combustible material.

R. Fuel gas tanks (cylinders) are equipped with fusible-metal safety devices. NEVER store tanks near radiators, furnaces, or other heat sources.
