Always have a fire extinguisher nearby.
7
Never use oxygen or fuel gas to blow soot or dirt from your clothes.
7
DO NOT
wear ragged clothes, as sparks can ignite the ragged or loose ends.
3
Always wear goggles or a helmet with the appropriate shade lens.
7
DO NOT
use shaded safety spectacles or unshaded face shield visors for cutting or welding. They DO NOT stop the harmful rays which cause eye damage.
3
Use gauntlet type gloves made from heat resistant material.
3
Secure cylinders to a trolley, wall or post to prevent them from falling.
3
All cylinders should be used and stored in an upright position.
7
Never drop or strike a cylinder.
DO NOT
use cylinders that have been dented.
3
Cylinder caps should be used when storing or moving cylinders.
3
Empty cylinders should be kept in specified areas and clearly marked EMPTY.
7
Never use oil or grease on any inlet connections, outlet connections or cylinder valves.
3
Examine hoses for cuts, burns or worn areas before each use. Also inspect fittings for damage. If any damage is found, replace immediately.
7
DO NOT
repair hose with tape.
3
Always use reverse flow check valves on torch and regulator. This greatly reduces the possibility of mixing gases in the regulator or hoses.
Reverse flow check valves are an important safety precaution.
3
Working pressure on the acetylene regulator should NEVER be set above 15psi (1 bar).
3
Keep all threads and unions clean and free from oil, dirt or grease.
7
Never apply oil or grease to any thread.
3
These instructions cover the use of the kit on mild steel. If used on any other materials, extra precautions will have to be taken.
3
Make sure that there is a good flow of air to the user and the tip, at all times. Use a welding fume extractor if conditions are poor or space is confined.
7
Never leave the gun alight and unattended.
3
For safety advice regarding gas bottles (oxygen and acetylene) refer to the supplier of the bottles.
3
Make sure bottle keys are in place at all times so that in the event of an emergency the valves can be turned off quickly.
3
If this kit is used in on business premises, extra safety is available by fitting Sealey SGA3/RFA or MFA and SGA4/RFA or MFA flashback arresters.
3
Keep hoses away from flame at all times. Make sure that hoses are laid flat where possible and not in a position where they can be run over
by vehicles, which would result in permanent damage.
3
LEAKING HOSES CAN KILL.
Check all joints weekly to make sure there are no leaks.
3
If hoses are not long enough, join them together with the manufacturers couplings only.
7
DO NOT
join damaged hoses, they must be replaced immediately.
3
Remember at all times
BLUE
= OXYGEN O
RED
= ACETYLENE A
3
At no time may you interchange parts contained in this kit with those of other manufacturers.
Only Sealey replacement items should be used.
3
Acetylene fittings have a left-handed thread and notches on hose unions to indicate this.
3
The regulators in this kit have no user-serviceable parts. All repairs/calibrations must only be
undertaken by a BCGA approved service agent.

2. CONTENTS
3.1.1. Make sure that the cylinders are secure as noted in safety precautions.
3.1.2. Whilst standing on one side crack each cylinder valve. Cracking is to quickly open and close the valve allowing gas to escape and
clear the valve of any foreign bodies.
p
WARNING!
If grease or oil is found, discontinue use of cylinder immediately and contact your gas supplier.
3.1.3. Attach oxygen and acetylene regulators to the appropriate cylinders. A wrench should be used to ensure tight connections. To tighten,
turn CLOCKWISE for OXYGEN, and ANTI-CLOCKWISE for ACETYLENE.
3.1.4. Regulator adjusting screws should be turned anti-clockwise to relieve the pressure on the diaphragm before opening the cylinder valves.
If this is not done, pressure from the cylinder can damage the diaphragm and render the regulator inoperative.
3.1.5. Both cylinder valve-to-regulator connections should be checked for leaks. Stand so that the cylinder valve is between you and the regulator.
Slowly open the cylinder valve. Use an approved leak detector.
