Usage Notes - YIHUA 706 Series Instruction Manual

4. The brushless fan comes with three standard nozzle sizes: large, medium,
small. When using the smaller nozzle the Hot air volume must be adjusted to
the maximum rate or set the temperature low and maintain it in a short time, to
avoid prolonged use which could damage the hot air unit.
5. In regards to the usage requirements, choose the appropriate Hot air nozzle,
different Hot air nozzle will cause the temperature to be slightly different, and
please maintain the distance between the outlet and the object must be at lea-
st 2mm.
6. When the soldering iron used for the first time, pay attention to check the iron
tip warming situation, let it temperature just be able to melt the tin wire, then
the iron tip layer deposited on the tin,then set to the desire temperature value.
7. Iron Tips temperature cannot be too high, high temperature will weaken tip
function. Interval not in use, should be adjusted low temperature.
8. Should clean up iron tip by use of clean sponge periodically, after using it,
pleae keep it clean, a new tin-plated layer to prevent tip oxidation.
VII. Display Notes
1. When the LED digital displays " --- ", it means the outlet temperature is below
100°C, the hot air rework station is in standby mode , and the handle is placed
on the handle's rack.
2. When the LED digital displays " S - E ", it means the soldering iron, Hot air
rework's sensor is having a problem or handle is un-plugged,if the case hasn't
been resolved it needs to replace the heating element (heating core's element
and sensor components).
VIII. Usage Notes
1. DO NOT install/Deinstall Nozzles with excessive force.
2. Only install nozzles when the unit is cool (room temperature).
3. When the first use the unit might started initially with white smoke, but this
soon will go away. Do not touch heat pipes, or let hot air spray face, it will hurt
human body.

4. Replace heater, be careful not to damage the grounding line!!
5. Replace the cable should pay attention to the order and color, can not take a
wrong!!
6. Replace the same type of heater or heating core!!
*Machine through the standard tested, then the actual temperature of the
aging test, part of the air gun steel barrel outlet slightly yellowish, are
normal, hereby instruction!
IX. Replacement Parts Instruction
Replacement of Hot Air rework heating element(Figure 2/Figure 3)
1. Ensure the Hot Air Rework is fully cooled down before replacing the element.
2. Figure, loosen the two screws on the handle
3. Turns the handle anti-clockwise until it comes off and then remove the
handle's cover.
4. Gently takes out the fan, loosen the three screws to remove the fixed wiring
board.
5. The wiring board vice versa, apart from the heater wiring board connection
cable, pay attention to the connection location.
6. Remove from the heat pipe heat body wrap body with mica paper, careful not
broken ground wire of the steel.
7. Wraps well with the new heater mica, inserted into the tube, the attention
heater to install in place.
8. According to the original location of the connection to connect heater.
9. As per the reverse procedure by open and back to the installed handle.
Replacement of the soldering iron's tip and
soldering iron heating core's element (Figure 4)
1. Unscrews the nut NO.1, and then removes the steel tube NO.2, followed by
removing the tip which is going to be replaced.
2. For the replacement of heating core's element can be performed by unscrewi-
ng the plastic cap NO.4,pulls out gently the heating core's element NO.6 along
with the circuit board NO.7, please carefully remember the connection of spri-
ng NO.5.
3. The iron core from the circuit board welding, the replacement of the heating
core, can be fitted well. Note that the order of the iron core wire connection.
