P2 - Replace Grommet
IMPORTANT NOTE: There are NO serviceable parts inside the pneumatic Hand Control .
1. If an air leak is suspected but there is no detected failure from test P1, there may be an air
leak at the lift grommet because the airline pins do not fit tightly. This lift grommet may be
replaced using the following steps.
2. Follow steps 1 - 1
1
in section B1.
3. Remove the battery on the side of the lift nearest to the grommet. See section E1.
4. Before starting, take note of the positions of the individual airline tubes inside the lift unit.
These should be marked in a way that they can be replaced in the exact same places.
Check the wire diagrams if not sure.
5. Lift away the blue oval plate to access the damaged grommet & clasp & flatten the rubber
using pliers to reduce the diameter enough to fit through the mounting hole. Then gently rock
the grommet back and forth while PUSHING the grommet through the lift control panel.
6. Disconnect the airline tubing from PCB to the grommet & discard the damaged grommet.
7. Replace the new grommet by gently PULLING the grommet through the lift control panel.
8. Reattach the internal air tubes and replace covers to reattach hand control airline.
9. Retest the entire pneumatic system to ensure that all hand control buttons function.
