3. Turn both valve connectors to the OFF position.
a. Turn the MAPP valve connector knob
(Fig. 2-1) clockwise until it stops.
b. Twist the oxygen valve connector cap
(Fig. 2-2) clockwise until it stops.
4. Twist each fuel cylinder into the correct valve
connector until hand-tight. Twist the MAPP fuel cylinder clockwise and the
oxygen cylinder counterclockwise.
5. Position both cylinders at a 45º angle with the valves at the top, to prevent
unwanted fuel from entering the hoses. The cylinders must be secure to
prevent rolling.
6. Wipe all torch and cylinder connections with a damp, soapy cloth. Bubbles
forming at the connections indicate a gas leak. Check the seating of all
components. Replace the cylinder with a new one if the problem persists at
the valve. Remove the tool from service if the problem persists as leaking
gas poses a fire hazard.
OPERATION
WARNING! Watch the hose for swelling when under pressure. A swollen hose
can rupture and become a fire hazard. Turn off the gas and remove the torch
from service for repairs if you do observe swelling.
The MAPP cylinder contains liquefied gas under pressure. The oxygen cylinder
contains pressurized gas only. Multiple oxygen cylinders will be used up before
replacing the MAPP cylinder is necessary. Conserve the limited supply of gas by
preparing the workpiece and work area before assembling the torch.
1. Open the MAPP gas valve (E) slowly until you hear a gentle hissing sound.
2. Point the torch away from bystanders, flammable materials or yourself.
Ignite the gas at the tip using a safe method. This will create a 4 to 6 inch
yellow flame. Black smoke may also issue from the torch.
3. Gradually open the oxygen valve (F) to introduce oxygen to the flame. The
flame colour will change to a bright blue and an inner flame will appear.
The outer flame must be no shorter than 4 inches to avoid damage to the
burner tip.
