Pressure Relief Procedure
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure in your spray gun
manual or in the SuperCat instruction manual.
Disassembly
1. Relieve the pressure.
2. See your spray gun manual to remove the power
cartridge. For the SuperCat alternator, remove six
screws, open the housing, and remove the power
cartridge.
3. Remove the turbine alternator.
4. Test the Coil: Measure the resistance between the
two outer terminals of the 3-pin connector (101a).
The resistance should be 2–5 ohms. Measure the
resistance between each outer terminal of the
3-pin connector and the turbine alternator housing
(B). The resistance should be infinite. If the readings vary from these values, replace the coil.
5. Remove the plastic plug (A).
6. Pro Xs Models only: Remove the retaining ring
(H) from the turbine alternator housing (B).
7. Insert a center punch or small metal shaft into the
hole in the back of the turbine alternator housing
(B). Hold the housing and lightly tap out the turbine
assembly (G).
8. Remove the larger bearing (2).
9. Slide the coil assembly (101) off the armature (D).
Inspect the coil for wear or damage and replace if
necessary.
NOTE: If only replacing the coil (101), continue by
following steps 5 through 11 on page 3.
10. Using a drift punch or small metal shaft, tap the
armature (D) out of the bearing (1) and fan (3).
CAUTION
To avoid demagnetization of the armature (D), never
place it in contact with, or in close proximity to, any
other armature or other ferromagnetic objects.
11. Clean the armature (D) shaft with a soft cloth.
Inspect the shaft for wear or damage. Replace the
armature (part no. 217590) if necessary.
