WARNING!
If the baseplate is removed, the axle assemblies
may fly out, because they are held in place by
compressed springs.
Removal of the plate is a two person operation:
One person needs to push down on the wheels
while the other slides out the base plate.
Replacing the Wheel-Axles Assemblies
1. Detach the end cap at the rear of the cart by remov-
ing the two screws from the rear end cap as shown.
NOTE:
The screws that secure the end caps to
either end of the Dynamics Cart are thread
forming screws and may require substantial force
to remove and reinstall. A #1 Phillips point screw
driver is required.
Replacing the Front End-Cap Attachments
