must be correctly oriented with the wheel bracket nearly vertical, as shown in Figure 17, before

applying pressure on the leverage bar.

the end being raised must be leveraged downward at the same time by two technicians.

4. The quick-release pins are re-inserted into their holes once the caster swing plates are leveraged

downward to lock them into place.

when moving the scanner. To switch from locked to unlocked, pull the spring-loaded ring out of the

deep groove (see following figure), rotate the ring 90 degrees to the shallow groove and release it.
