Safety And Operating Instructions.

Helium is a natural non flammable gas, which with simple instructions that are followed is easy to use.

The following safety and operating instructions are advised to be practiced and followed every time a balloon inflator is attached to a cylinder. All caution statements must be strictly followed; Failure to adhere to these instructions may result in personal injury or property damage.

Caution. This balloon inflator is designed to fill balloons quickly and safely. Exercise extreme caution when handeling pressurised gas cylinders.

Cylinder Care.

Secure the cylinder to be used so that it will not fall over. The best option is to use a specially designed cllinder stand or trolly.

Rip off the plastic cap from the cylinder outlet and inspect the cylinder valve for thread damage, dirt, dust, oil or grease.

Crack open the cylinder valve quickly prior to use, this will remove any foreign objects from the inside of the valve port.


If the cylinder valve is opened too much without the cylinder being secured it may fall over due to the force of the gas escaping.

Always stand to the side of the cylinder when completing this operation and DO NOT stand infront of the valve !

  • DO NOT move the cylinder with the inflator connected.
  • DO NOT drop or strike the cylinderor inflator.
  • DO NOT store in direct sunlight or apply heat.


Attaching the inflator to the Cylinder.

Ensure the O ring on the inlet of the inflator is in place and that it is not damaged and attach the inflator to to the cylinder by turning the thread or hand tightening ring clockwise into the cylinder valve thread. Never use grease or oil under any circumstances on either the cylinder valve or the inflator seal. Open the valve anti-clockwise slowly or the sudden rush of released cylinder pressure may make your inflator defective.

Check all connections for leaks before filling balloons. Put the neck of the balloon over hte rubber nozzle, hold the balloon firmly, gently bend the nozzle to inflate the balloon and release when the desired balloon size is reached.

Removing The Inflator from the Cylinder.

Make sure that the cylinder valve is fully turned off.

Release the pressure from the inflator by pushing or bending the balloon-filling nozzle of your inflator.

Turn your regulator or hand tightening ring anti-clockwise and continue until the inflator is fully disengaged.

Inflate balloons no earlier than two hours before function, as latex balloons will start to deflat after 8 hours.

Do's & Don'ts to keep you safe when using Helium.

  • Read the safety precautions on the cylinder label before using the Helium.
  • Always store Helium cylinders in a well ventilated area and secure in an upright position so that they cannot fall over damaging the equipment and things around it.
