M2 - Replace Trolley Wheels
Ensure that the lift is always fully supported. Take great care in
protecting the PCB. There is a tendency to turn the lift over, thus
damaging or breaking the aluminum standoffs that support the PCB.
1. The same procedure is used to replace any manual or charger trolley wheel assembly.
2. Insert the pin ends of the snap ring removal tool into the trolley wheel snap ring holes.
3. Slowly, firmly squeeze the handles of the snap ring removal tool together to open the
snap ring out of the trolley wheel shaft groove to remove it.
4. Carefully slide the trolley wheel free from the shaft while taking care not to lose the
washer.
5. Place the new trolley wheel onto the shaft past the snap ring groove.
6. Place a new snap ring centered against the shaft and slightly pry it apart gently with the
snap ring tool until it is open enough to allow it to be slipped into the groove. Ensure that
trolley wheels are straight and inline with each other.
