MAINTENANCE: REPLACING THE VENTURI
If vacuum is still low after checking and cleaning the
Venturi, it will have to be replaced.
1. Open the Desoldering Handle.
2. Remove the Chamber filter.
3. Use an appropriate slotted screwdriver to
remove the Venturi cartridge. The
cartridge should screw out normally. Do
not force.
4. Use a torque driver to install the Venturi
Cartridge to a torque of 10 to 15 inch-
pounds.
MAINTENANCE: CLEANING THE DESOLDERING HANDLE
1. Remove the Desoldering Cartridge from the handle.
2. Disconnect the power cord and air hose from the handle.
3. Remove the cartridge and chamber seals.
4. Clean the handle in a mild vapor degreaser or ultrasonic bath.
5. Allow time for the tool to dry, and then replace the seals.
MAINTENANCE: CLEANING THE WORKSTAND
The exterior of the workstand can be cleaned with a soft bristle brush and a mild
detergent. The cradle can be cleaned separately by removing the attachment screw,
located on the bottom of the workstand.
MAINTENANCE: REPLACING THE SWIVEL BUSHING
1. Turn off shop air.
2. Unscrew air hose from the desolder tool.
3. Using an adjustable wrench, unscrew the swivel bushing.
Note: the swivel bushing is secured in the tool with a sealant so it may be
difficult to remove.
4. When you remove the swivel bushing, you will see a spring. Keep it in place.
5. Make sure the area where the swivel bushing screws in is clean of foreign
materials (this may require removing the spring temporarily).
6. Wrap Teflon pipe sealant around the end of the swivel bushing and with the
spring in place, screw the swivel bushing into the back of the desolder tool
using a torque wrench to 30-50 in-lbs.
7. Screw in the air hose onto the swivel bushing.
8. Turn on shop air and check for leaks.
MAINTENANCE: REPLACING THE UPPER CHAMBER
For an illustration of many of the steps in this technique, see following page.
1. Remove the power cord from back of the upper chamber.
2. Open the upper chamber.
3. Insert a long, thin tool in the back hinge where the upper chamber hinges to
the tool handle assembly.
4. Push tool inwards and pull the upper chamber away from the tool handle
assembly.
5. Completely remove upper chamber.
6. Remove old pins and springs from the front and back pin bores.
7. Insert two new springs, and two new hinge pins, into the pin bores on either
end of the tool handle assembly. Ensure that the smaller, tapered ends of the
hinge pins, are pointing outward.
8. Install upper chamber assembly onto tool handle assembly by pushing the
hinge pins into their bores until the arms of the upper chamber assembly will
slide onto the handle assembly. The hinge pins should slide out into their pilot
holes in the arms of the upper chamber.
