The R-1 0-40-600 adjustable pressure regulator (0 - 40 psi) was designed for industrial use with FG-2 (propylene), propane, or Mapp® gas
supplied in disposable 14 - 16 oz. cylinders and PREST-0-LITE® Swirljet® LPG air/fuel tips sizes 3, 4, and 5.
Do NOT use the SJ-6LPG Swirljet® tip with the R-10-40-600.
ATTACHING PRESSURE REGULATOR TO CYLINDER AND TIP.
1. Make sure the regulator valve knob is in the closed
position by turning knob in the clockwise direction. Do
NOT use excessive force which may cause the knob to
bind. Closing the knob prevents fuel gas from escaping
while attaching the regulator to the cylinder.
2. Attach Swirljet® tip to the swivel nut part of the regulator and then by holding tip in the desired position, hand
tighten the swivel nut to lock the tip in place.
3. Attach the regulator to the cylinder by turning cylinder
clockwise and tighten HAND TIGHT.
Be sure this information reaches the operator.
You can get extra copies through your supplier.
Do not use the SJ-6LPG tip with the regulator.

SAFETY PRECAUTIONS
Every worker should be familiar with the following personnel protection and fire prevention
measures:
1. Read and follow all precautions on the cylinder label.
2. Keep cylinder and appliances out of the reach of children.
3. ALWAYS disconnect regulator from cylinder when not in use. Be sure to close the valve knob whenever unit is not in actual operation.
4. This regulator is for use with FG-2 (propylene), propane and Mapp® gas only. NEVER use acetylene
or any other gas.
5. Fuel gas is extremely flammable when mixed with air and may form explosive mixtures with air.
Operate appliances ONLY in well-ventilated areas.
6. Always check for gas leaks. Light the torch and then (using a brush) apply soapy water around the
regulator cylinder connection, at the tip-to-regulator connection, and at all regulator joints. If leakage
is indicated, by bubbling at any of these points, shut off the torch and tighten the connections. Relight
and retest. Do NOT continue to use leaky equipment. Do NOT test for leaks with a flame.
7. Never store cylinders in areas of habitation such as inside home or office.
8. NEVER store or transport cylinders in car trunks, drawers, cabinets or other confined spaces, or in
any location where the temperature may exceed 120° F (49° C), or where sparks, flames, or combustible material may be present.
9. Do NOT use lighted torch in any place where flammable or explosive gases, liquids, or other materials may be accidentally ignited.
10. Do NOT leave lighted torch unattended. ALWAYS turn off torch when stopping work or when leaving
work area.
11. DO NOT solder or heat a container that contains or has contained flammable liquids or vapors, such
as gasoline, unless the container has been completely purged of all traces of flammable liquids and
vapors.
12. Do NOT attempt to force heat or warm the cylinder in any way to increase cylinder pressure or gas
flow. Move cylinder to a warm location if necessary.
13. When the cylinder is exhausted, ALWAYS discard it in a safe place. Do NOT puncture or incinerate.
NEVER attempt to refill it with any gas or liquid.
14. Do NOT alter equipment.
15. Fumes and gases can harm your health. Keep your head out of the fumes. Do not breathe fumes and
gases caused by the flame. Use enough ventilation. The type and amount of fumes and gases
depend on the equipment and supplies used. Air samples can be used to find out what respiratory
protection is needed.
16. Heat rays (infrared radiation from the flame or hot metal) can injure eyes. Wear correct eye and body
protection.
17. For more information on safety and health, refer to the following publications: (1) ESAB Form 2035;
(2) OSHA Title 29 CFR 1910, Sub-part Q, available form U.S. Government Printing Office, Washington, D.C. 20402; (3) American National Standard Z49.1, available from the American Welding Society, 550 N.W. LeJuene Rd. Miami, FL 33126.
LIGHTING TORCH AND FLAME ADJUSTMENT
1. Open the regulator knob one full turn (counter-clockwise), and immediately light flame at tip with a friction
lighter. Do NOT use a match. Use of a match can seriously burn your hand.
2. After the tip has been lit, adjust regulator valve for the
proper flame setting. See Figure 2 Flame Settings
below.
3. As contents of the cylinder are withdrawn, pressure in
cylinder may drop slightly. Be sure to readjust the regulator as necessary to maintain the correct flame setting.
4. Shut off the regulator when work is completed. Always
remove regulator from cylinder when not in use.
Correct Adjustment
Concentrated flame. Dark blue points extend from tip approx. 1-1/2 tip
diameters beyond end of tip. Tip operates cool when correctly adjusted.
Too Little Gas
Soft Flame - pressure too low. Tip will overheat. Dark blue portion of
flame barely visible from end of tip. Flame pink in color.
INVERTED OPERATION
1. When using FG-2 (propylene) or propane, the cylinder
may be used in an inverted or horizontal position when
using Swirljet® tips size 3 and 4. However, prolong use
in this position may cause liquid fuel to enter the regulator and cause the flame to flare. If this happens, turn
the cylinder upright or close the regulator knob until the
liquid evaporates permitting normal operation. Inverted
use with Swirljet tip size 5 is not recommended.
2. When using Mapp
inverted or horizontal position is not recommended.

SWIRLJET® TIP DATA
TIP COPPER TUBING SIZE, IN. DIA. APPROX. WORK TIME
SIZE SOFT-SOLDER SILVER-SOLDER OF DISPOSABLE CYLINDER
3 1/4 TO 1 1/8 TO 3/8 6 HR.
4 3/8 TO 1- 1 /2 1/4 TO 5/8 3 HR.
5 1 TO 2-1/2 5/8 TO 1-3/8 1 HR.
MAINTENANCE
1. If the flame length cannot be maintained, resulting in
overheating the tip, the orifice nozzle P/N 21478 SJ-3LPG, P/N 21479 - SJ-4LPG, P/N 21480-SJ-5LPG
or filter screw (P/N 998311) in the back end of the tip
may be clogged. Use an 1/8 in. Allen wrench to remove filter screw, and then tap the tip lightly to dislodge the nozzle. Blowing air through the front end of
the orifice nozzle may dislodge any dirt or grit that may
have lodged in the small orifice. Do not clean orifice
hole with a wire or similar object. The orifice hole can
easily become enlarged causing improper operation. If
orifice nozzle cannot be cleaned, replace both orifice
nozzle and filter screw.
2. Periodically, check for leakage by brushing soapy water solution around all regulator valve joints and connections after lighting the torch. If leakage is noted by
bubbling of the solution at any point and it cannot be
stopped by simply HAND tightening, then the regulator
should be replaced. Do NOT operate with regulator in
faulty condition. Do NOT attempt to repair the regulator.
