Maintenance: Replacing The Swivel Bushing; Maintenance: Replacing The Upper Chamber - Metcal MX-500 Manuel D'utilisation

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.
For an illustration of many of the steps in this technique, see opposite 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.
9. Check the functioning of the slide latch and hinge by operating the latch, opening
and closing the upper body a few times. The parting lines (gaps) between the rear
of the chamber and the top rear of the right handle should be parallel.
