3. DO NOT remove the regulator/flowmeter from a cylinder
without first closing the cylinder valve and releasing gas in
the regulator/flowmeter high and low pressure chambers.
4. TURN OFF when equipment is not in use for extended
periods of time, shut off the gas at the cylinder valve and
release the gas from the equipment.
5. OPEN the cylinder valve SLOWLY. Close after use.
USER RESPONSIBILITIES
This equipment will perform safely and reliably only
when installed, operated and maintained, and repaired in
accordance with the instructions provided. Equipment must
be checked periodically and repaired, replaced, or reset
as necessary for continued safe and reliable performance.
Defective equipment should not be used. Parts that are broken,
missing, obviously worn, distorted, or contaminated should be
replaced immediately.
The user of this equipment will generally have the sole
responsibility for any malfunction, which results from improper
use, faulty maintenance, or by repair by anyone other than an
accredited repairer.
CAUTION
Match regulator/flowmeter to cylinder. NEVER
CONNECT a regulator/flowmeter designed for a
particular gas or gases to a cylinder containing any
other gas.

OPERATING MANUAL
INSTALLATION
1. Remove cylinder valve plastic dust seal. Clean the cylinder
valve outlet of impurities that may clog orifices and
damage seats before connecting the regulator/flowmeter.
Crack the valve (open then close) momentarily, pointing
the outlet away from people and sources of ignition. Wipe
with a clean lint free cloth.
Match regulator/flowmeter to cylinder. Before connecting,
2.
check that the regulator/flowmeter label and cylinder
marking agree and that the regulator/flowmeter inlet
and cylinder outlet match. NEVER CONNECT a regulator/
flowmeter designed for a particular gas or gases to a
cylinder containing any other gas.
3. Connect the regulator/flowmeter inlet connection
to cylinder or pipeline and tighten it firmly but not
excessively, with a suitable spanner.
4. Connect and tighten the outlet hose firmly and attach the
hose to the welding machine with a suitable hose clamp.
Ensure no gas leakage. The flowmeter must be in the
vertical position to read accurately.
OPERATION
With the regulator/flowmeter connected to cylinder or pipeline:
1. Stand to one side of regulator/flowmeter and slowly open
the cylinder valve. If opened quickly, a sudden pressure
surge may damage internal regulator/flowmeter parts.
2. Since the regulator is a preset type, no adjustments to the
regulator are necessary. Before opening the cylinder valve,
be sure that the flow adjusting valve is in a finger-tight
"OFF" position (clockwise).
3. Slowly and carefully, open the cylinder valve until the
maximum pressure registers on the high pressure gauge.
CAUTION
DO NOT purge oxidising or flammable gases in the
presence of flame, lit cigarettes, or other sources of
ignition or in a confined space.
