SECTION 1:
7300/8300 TOUCH PANEL/CIRCUIT BOARD MOISTURE / CORROSION INSPECTION: (TSB No. 017300- -00)
FOR SAFETY:
Before leaving or servicing machine, stop on level surface, set parking brake, turn off
machine, and remove key.
1. Disconnect battery cables from the batteries.
WARNING:
Always disconnect battery cables from machine before working on electrical
components.
2. Remove the touch panel from the machine instrument panel housing.
3. Remove the surrounding rubber bezel. (Refer to FIG. 1)
4. Inspect the lower outside perimeter of the touch panel assembly for green copper oxide formations. Refer to
Fig. 1.
5. Replace the touch panel assembly if excessive corrosion is found.
6. If the touch panel assembly does not need to be replaced, add clear dielectic grease (TENNANT PN# 86385)
to the lower outside perimeter of the touch panel.
7. Clean the inside channel of the bezel and attach the bezel to the touch panel assembly. Wipe any exposed
dielectic grease from the assembly surfaces.
8. Ensure the switch plugs did not pull away from switches, before reinstalling touch panel. Reconnect the touch
panel and the battery cables to the machine.
9. Check the machine functions and run the self test.
