1. HANDPIECE INJECTABLE PRODUCTS
Refer schematic diagram No 2: Handpiece component
breakdown.
Before commencing, attention must be given to following
the chemical manufacturer’s safety instructions at all times
and gloves must be worn at all times to prevent chemicals
contacting the hands. Please ensure the handpiece and
feed tube have been thoroughly cleaned and ushed out as
covered by section III of this booklet, care and maintenance
of injector.
a. The injector has been supplied with a 15ml injectable
cylinder.
Please refer to the pharmaceutical manufacturer’s
administration instructions for selection of needle to be
used.
b. Fit the selected needle as specied in the pharmaceuticals
manufacturer’s administration instructions, to the luer
tting (diag. 2 -1).
c. Using pliers and 9/16” AF open ended spanner, unscrew
the inlet adaptor (diag. 2 - 26) from the handpiece
and check that the inlet valve and spring (diag. 2 -
25) are clean, and facing in the direction as shown in
the handpiece diagram. Re-t the inlet adaptor to the
handpiece and hand tighten with pliers and open ended
spanner.
dThe handpiece is now set up ready for connection
to the draw off system for the injectable treatment of
livestock.
2. INJECTOR OPERATED BY LP-GAS PORTABLE
OR PROCESSOR
Refer Schematic Diagram No 3: Applicator setup for
operation by LP-Gas Portable or Processor.
WARNING: You must not t or use faulty, poor quality
or incompatible associated parts or components, and in
particular the use of a gas regulator and valve assembly
other than those components supplied with the product.
You must not repair, alter or modify the product, other
than those carried out by NJ Phillips Pty Limited or it’s
authorised agent, and in particular interference with or
modication in any way to the injector gas tube or other
components relating to the use of LP gas to operate the
product. Any occurence of these issues will VOID the
warranty. See warranty statement page 10.
a. Fill the gas cylinder with liquid propane gas (LPG).
WARNING: Gas cylinders must only be lled by
authorised lling agents.
NOTE: DO NOT OVERFILL GAS CYLINDER: It is
important not to overll the gas cylinder as liquid gas
may enter the injector and freeze the trigger valve. When
lling, shut off the lling exhaust valve as soon as the
rst cloudy vapour is observed coming from the valve.
Do not ll until liquid gas is pouring out and freezing up.
If liquid gas enters the gas tube, release the regulator
tting on the gas tube, and the liquid will vaporise.
b. Connect the gas regulator and valve assembly to the gas
cylinder as covered by the instruction leaet supplied
with the regulator and valve assembly, and detailed in
sections 1 to 5 of that procedure.
c. Connect the gas tube to both the injector and the outlet
port on the regulator, and hand tighten.
Set the gas operating pressure at 414 to 550 Kpa (60-80
psi) on the pressure gauge as covered by sections 6 and
7 in the instruction leaet supplied with the regulator and
valve assembly.
NOTE: The gas pressure may require adjustment by the
regulator within the specied limits to achieve satisfactory
delivery of injectable products, and may vary depending
on climatic conditions, use of the injectable product in the
upright or inverted position, or the type of needle used.
d. The injector is now set up ready for the vaccine bottle to
be connected to the appropriate feed tube and the feed
tube to the injector.
e. Connect the one end of the feed tube to the inlet adaptor
on the applicator and the other to the draw off system.
Ensure the feed tube springs are securely screwed over
the feed tube in an anticlockwise direction. This will
prevent the feed tube kinking.
i. NOTE: The injector must only be used with the gas
cylinder placed in the upright or vertical position, so
that gas and NOT liquid LPG passes through the
valve on the gas tube. Otherwise the liquid LPG
will freeze up the valve and the injector will cease
to operate. In this case, release the regulator tting
on the gas tube for the liquid LPG to vaporise, then
re-tighten.
ii. It is essential, to prevent injury to the user, that you
refer to the WARNING STATEMENTS relating to
the use of the injector when operated by LP gas, as
covered in the Powermaster handbook page 2, and
the instruction leaet supplied with the regulator and
valve assembly, instructions for connection of gas
regulator to LP gas cylinder.
f. To prime the injector set the dose at 15ml and with the
instrument held vertically with the needle pointed upwards
depress the trigger a number of times until the injectable
product is expelled from the needle in an unbroken
stream and all air bubbles have been eliminated from
the cylinder.
g. To Set Required Dose:
iDose levels and application of the injectable product
must be set in accordance with the pharmaceutical
manufacturer’s administration instructions.
ii. Turn the dose adjustor in an anticlockwise direction to
decrease dose, and a clockwise direction to increase
the dose, as indicated by graduations on the dose
adjustor sleeve.
iii. To be sure of complete accuracy, the dose must be
checked with a calibrated measuring cylinder.
iv. Cylinder ll rate and delivery pressure can be varied
with adjustment to the gas pressure on the regulator
between 414 to 550 Kpa (60 - 80 psi).
The minimum pressure should be used to achieve
acceptable lling rate and delivery speed.
h. The injector is now set up ready for the injectable
treatment of livestock.
i. WARNING: Care must be taken to ensure the liquid
does NOT come into contact with any part of the
operators body. Chemicals may injure the operator.
WARNING: At the close of each days work, or
on completion of treatment of livestock, to avoid
possible unsafe or hazardous situations, the
regulator valve must be fully closed by turning in a
clockwise direction, as indicated
