Assembly  
It is important that your read the entire manual to become familiar with the unit BEFORE you use the  
Propane Torch. Before preparing to use your Propane Torch, be sure that you have all parts described in the  
Parts List.  
Your Propane Torch comes fully assembled.  
Operation  
To assist you with operation please refer to the Operational Figure on this page. You should also refer  
to the Assembly Diagram on page 7 and the Parts List on page 6.  
Never force the tool or attachment to do the work of a larger industrial tool. It is designed to do the  
job better and more safely at the rate for which it was intended.  
This tool is designed to be used and operated on L.P. Gas (Propane) which is found in a disposable  
Propane bottle.  
Step 1)  
Make sure that the Hand Wheel (13) is tightened completely before attaching the torch.  
Firmly insert the Gas Inlet (1) into the Propane canister and screw the Gas Inlet into place. It  
is normal for some propane to escape while doing this. If you continue to smell or hear gas  
leaking, tighten to torch or reinstall it.  
Warning: Make sure the work area is clear of people and animals. Always move the  
Burner Nozzle in a controlled manner. Always be alert to the path of the flame!  
Step 2)  
Step 3)  
While making sure that you are clear of the outlet of the Torch, open the Hand Wheel slightly  
to allow L.P. gas to flow to the Burner Nozzle (20). Draw out the flame by placing a long lit  
match stick or similarly lit device near the Propane Torch’s Burner Nozzle. This will create a  
flame.  
Adjust the flame to a reasonable level by turning the Hand Wheel (13).  
Note: The lit burner should operate with a blue flame with a small yellow tip.  
Adjust the knob if the flame is sputtering or popping.
