4. Prior to installation, make sure the nozzle has no clogged orifices.
5. For 15,000 psi models - Apply 3 - 4 wraps of Teflon tape to male
connection thread on the barrel. Apply anti-seize compound over the
sealant tape for additional protection against galling in connection
threads. Wrench connection 1 1/2 - 2 turns past hand tight. A minimal
thread engagement of four (4) threads should exist on all Jetstream NPT
pipe connections.
For 22,500 psi models - Apply anti-gall compound to the gland threads
and male cone on control gun front barrel. DO NOT use Teflon tape.
Check blast nozzle size before installing the nozzle. Make sure the nozzle
orifices are not too small in order to prevent excessive system pressure
when the gun's control valve trigger/pedal is depressed.

smooth jaw plier wrench (JS PN 64119) to tighten nozzle. Avoid using
pipe wrench as wrench marks will cause nozzles to crack and fail.

installed prior to use or the nozzle may unscrew from the lance while in
service and cause the lance to blow back toward the operator.
8. With nozzles requiring adjustment, always read applicable instructions.
9. Blocked orifice(s) can cause excessive system pressure and failure. If
orifice(s) appear clogged or partially blocked with dirt or debris, remove
nozzle from control gun or lance and clean immediately.
10. Remove nozzle from service if:
A. Nozzle is split or damaged;
B. Nozzle sidewall is worn by more than 25% at any point;

lances must have a minimum 22,500 psi burst rating. 8,000 psi operat-
ing pressure flex lances must have a minimum 18,000 psi burst rating.
3. Do not use a flex lance that has an unknown burst or unknown
manufacturer's operating pressure rating.
