November, 1996
This sheet covers use of PREST-O-LITE tips which
attach directly to the 403 handle. Supplementary in-
structions are supplied with SWIRLJET air-fuel gas (F-
15-132), SWIRLJET air-acetylene tips (F-15-132), and
with leak detectors (F9372).
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 left-
hand-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 lock-
ing 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 in-
structions 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 pres-
sure for testing, you may wish to reset it before light-
ing the flame, since only a few tips require a pres-
sure 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 nec-
essary, by changing the setting of the regulator pres-
sure-adjusting screw or partially closing the torch

needle valve.
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, re-
move the valve stem assembly and wipe the seat-
ing surfaces on the stem and in the body with a
