INSTALLATION
5. The nozzle is installed onto the blast hose
by screwing the bell shaped inlet end of the
of the nozzle into the nozzle holder. Make
sure the nozzle washer is located as shown
below.
6. Continue to screw the nozzle into the nozzle
holder until the nozzle reaches the end of
the nozzle holder thread, then tighten the
nozzle until it is hand tight. Do not over-
tighten the nozzle in the nozzle holder or
use any tools to tighten the nozzle.
7. If the nozzle is to be used without the
silencer, the bump guard must be installed
and securely fitted to the outlet end of the
nozzle. Hand tighten the bump guard in the
same way the nozzle is hand tightened.
Note:
The bump guard thread is different to
the nozzle inlet thread to ensure the nozzle
cannot be installed backwards.
8. When the nozzle is installed into the nozzle
holder as per the instructions above,
check to make sure the connection is tight
and there is no movement between the
nozzle holder and the nozzle. Check that
the nozzle holder is firmly secured to the
blast hose.
9. The nozzle is removed in the reverse order
to the above sequence.
Note:
Ensure the system pressure is
isolated prior to removing the nozzle.
