P2 - Replace Grommet
There are NO serviceable parts inside the pneumatic Hand Control.
1. If an air leak is suspected but there is no detected failure, 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 - 11 in section B1.
3. 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.
4. 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.
5. Disconnect the airline tubing from the grommet & discard the damaged grommet.
6. Reattach the internal air tubes and replace covers to reattach hand control airline
7. Replace the new grommet by gently PULLING the grommet through the lift control
panel.
8. Retest the entire pneumatic system to ensure that all hand control buttons function.
