Remove main body cap, then place the refillable fuel cell into 

the holder. Replace the body cap tightly. (Refer to diagram.)   

To ignite, Push Safety Lock toward Flame Nozzle. Place thumb 

on Ignition button and apply downward pressure. Your MT-11 

is now ignited and ready to use. Note: If no flame appears, 

adjust the regulator on the fuel cell and activate the ignition 

button again. As the gas in the fuel cell is consumed, the 

regulator may need to be adjusted to ensure a proper flame. 

When the ignition button is released, there will be a short delay 

before the flame is completely extinguished and the Safety Lock 

will move to locked position. When the MT-11 is not in use, 

remove the fuel cell.
TO FILL/REFILL FUEL CELL:

Use only Master Ultratane® Butane fuel to fill fuel cell. Remove 

fuel cell from Microtorch or package. Hold fuel cell firmly with 

refill valve pointing up. Place nozzle of butane canister down 

onto refill valve and press butane canister down and up in 

short durations until fuel cell is filled. A pumping action is 

required when filling fuel cell. It typically requires two or three 

quick pumps to fill fuel cell. If you do not follow proper filling 

instructions, the valve may stick open, causing butane to leak.

After filling fuel cell, please verify that valve has seated 

properly by visual inspection. Consult factory if problem 

exists. Read and follow instructions before using. Keep away 

from children. After filling: fuel cell contains gas under 

pressure. Do not use near open flames, heaters or 

combustibles. Store properly when not in use. Always make 

sure Microtorch is cool before removing fuel cell. Remove fuel 

cell before storage. Do no store fuel cell above 104°F/40°C. 

CAUTION: Flame appears invisible in sunlight and could cause 

severe injury if not used with extreme caution.
