5 Assembly
1.
Fit an air coupler nipple, not supplied, to suit the available air line system into the small intake valve shown in fig.1.
2. Fit the twin outlet barrel to the receiver securely, ensuring air tight integrity of the connection.
In use, it is required that the angle flange is carrying handle side (opposite side to air release
trigger) of the receiver when the task wheel is horizontal (fig. 2).
When the task wheel is vertical the angle flange should be the same side as the air release
trigger (fig. 3).
3. Check the integrity of the pressure gauge and safety relief valve connections.
6 Operation
6.1 Horizontal wheel mode (fig. 2)
1.
The assembled unit barrel angle flange will be on the opposite side to the air release trigger. See also 5.2.
2. Place the wheel with tyre on to a rim stand and clamp in position through the central hub.
The tyre and wheel must be off the ground. The bottom bead must already be correctly seated.
3. Connect an air line to the quick coupling and open the intake valve to pressurise the receiver to the working pressure.
Normal working pressure is from 6 to 8 bar / 87 to 120 psi.
The pressure required in the receiver will depend upon experience, the tyre size and the tyre condition.
4. With one hand on the carrying handle and the other on the trigger release handle, aim the twin outlets, directly opposite
(*180°) the tyre valve stem. Target the middle of the gap, an angle of 50° to 70° from the vertical to bring the angle flange
into contact with the rim of the wheel, now the stop or pivot point. Once positioned, keeping the angle of approach, move
the twin outlets away approximately 40 mm to avoid premature contact with the tyre as it quickly expands with the force of
mains air.
5.
Apply a steady flow of air into the valve stem whilst simultaneously returning the twin outlets toward the tyre and rim
fulcrum position.
6.
Hold this position firmly and gently press the air release trigger with your index finger, directing the receiver air into the
gap between the tyre and rim.
6.1.
Horizontal wheel mode. (fig.2)
6.1.1. The assembled unit barrel angle flange will be on the opposite side to the air release trigger. See also 5.2.
6.1.2. Place the wheel with tyre on to a proprietory rim stand and clamp in position through the central hub.
The tyre and wheel must be off the ground. The bottom bead must already be correctly seated.
6.1.3. Connect an air line to the "quick" coupling and open the intake valve to pressurise the receiver to the 'working pressure'.
Normal working pressure is from
87
to 1
20
psi /
6
to
8
bar.
The pressure required in the receiver will depend upon experience, the tyre size and the tyre condition.
6.1.4. With one hand on the carrying handle and the other on the trigger release handle, aim the twin outlets, directly opposite (*180°) the tyre
valve stem. Target the middle of the gap, an angle of 50° to 70° from the vertical to bring the angle flange into contact with the rim of
the wheel, now the stop or pivot point. Once positioned, keeping the angle of approach, move the twin outlets away
approximately 40mm to avoid premature contact with the tyre as it quickly expands with the force of mains air in 6.1.5..
6.1.5. Apply a steady flow of air into the valve stem whilst simultaneously returning the twin outlets toward the tyre and rim fulcrum position.
6.1.6. Hold this position firmly and gently press the air release trigger with your index finger, directing the receiver air into the gap between the
tyre
and rim.
6. OPERATION
6.2.
Vertical wheel mode. (fig.3)
6.2.1. The assembled unit barrel angle flange will be on the same side as the air release trigger. See also 5.2.
6.2.2. Place the wheel with tyre against a wall, for example.
The tyre must be off the wall and the back bead must already be correctly
seated.
Use
a wedge if required to set the bead.
6.2.3.
Connect an air line to the "quick" coupling and open the intake valve to pressurise the receiver to the 'working pressure'.
Normal working
pressure is from
87
to
120
psi /
6
to
8
bar.
The pressure required in the receiver will depend upon experience, the tyre size and
the tyre condition.
6.2.4. With one hand on the carrying handle and the other on the trigger release handle, aim the twin outlets, directly opposite (*180°) the tyre
valve stem. Target the middle of the gap, an angle of 50° to 70° from the horizontal to bring the angle flange into contact with the rim of
the wheel, now the stop or pivot point. Once positioned, keeping the angle of approach, move the twin outlets away approximately 40mm
to avoid premature contact with the tyre as it quickly expands with the force of mains air in 6.2.5..
6.2.5. Apply a steady flow of air into the valve stem whilst simultaneously returning the twin outlets toward the tyre and rim stop position.
6.2.6. Hold this position firmly and gently press the air release trigger with your index finger, directing the receiver air into the gap between the tyre
and rim.
6.3.
Notes for both horizontal and vertical process
6.3.1. If above procedure does not set the bead, repeat the procedure at a higher pressure or try with the receiver vertical in (fig.2); horizontal
in (fig.3).
6.3.2.
After the bead has set to the wheel, stop the air flow to the valve stem, fit a valve core in the stem, move the wheel assembly to a tyre
inflation cage and inflate the tyre to the manufacturer's recommended operating pressure.
6.3.3. * In some instances on smaller wheels it may be better to position the barrel closer to the valve stem (fig.4). See also 6.1.4 and 6.2.4.
