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

MAINTENANCE
1. If the needle valve turns too freely, or there is gas
