A. Replacing the Hot Air Gun heating element
1. Remove the screws which secure the handle and slide the cord
tube.
2. Open the handle. Disconnect the ground wire and remove the
pipe.
3. Remove the heating element by disconnecting the terminal.
4. Insert a new heating element and reconnect the terminal. Handle
the heating element with care. Never rub its wire. Reconnect
the ground wire after replacing the element.
5. Assemble the handle in the reverse order of disassembly.
B. Care for the Soldering Iron tip.
Always keep the solder­plated section of the tip coated with a small
amount of solder. If the tip is coated with oxide, the tip’s heat conductivity
will be lowered. Coating the tip with a small amount of fresh solder
ensures maximum heat conductivity.
OPERATING PROCEDURE
E.. SMOKE ABSORBER
1. Wait until the soldering iron reaches the set temperature and
stabilizes.
2. Set Vacuum Control to
smoke absorber
.
3. Check if the Vacuum Indicator lights up.
4. Fumes absorbed will pass through a filter and be blown out thru the
hot air gun. So the smoke that is blown out from the hot air gun
during soldering is already filtered.
IMPORTANT: Filters should be cleaned and replaced
regularly so that it would not clog up the air path and will
effectively clean the toxic fumes produced during soldering
process.
CARE and MAINTENANCE

A. Soldering Iron
1. Install the solder wire to the soldering iron holder as in Figure 2.
2. Connect the soldering iron cord assembly to the 5­pin output
terminal found at the lower portion of the main unit. Please refer to
item 8 from the Control Panel Guide.
3. Place soldering iron to the soldering iron stand as shown above.
B. Hot Air Gun
The Hot Air Gun holder was installed on the station upside down
for packaging purpose. To set up the Hot Air Gun holder:
1. Loosen the two screws that secure the holder to the station.
2. Turn the holder right upside.
3. Fasten the two screws back.
4. Place the hot air gun on the holder in preparation for usage.
Note: Make sure the screw at the center of the base of the main unit
has been removed. This holds the pump in place during transportation
and needs to be removed before using the equipment.
C. Smoke Absorber
Attach the smoke absorbing tube to the vacuum cap. Make sure that
the cord connections are free from any tangles.
