3. Caster Height: Raising and Lowering
• Raise or lower casters (to adjust case height) by
rotating casters’ vertical adjustment rings.
• Rotate vertical adjustment ring clockwise to lower
caster (and increase height of case).
• Rotate vertical adjustment ring counter-clockwise
to raise caster (and decrease height of case).
4. Caster Rolling Capability: Unlocking
• Important! Case is shipped with caster mechanisms
factory set at ON (locked) to prevent case from rolling.
• Unlock casters by pressing OFF on the caster
mechanism.
• See illustration at right.
5. Carefully Remove Case From Skid
• Check that casters are lowered as far down as
they will go (as instructed in step #4).
• Use handles to carefully slide case to edge of
skid (see illustration at right).
• Caution! 4 people are required for this task!
• Carefully lower to floor (using ramp if available).
• Slide skid from under case as required.
• Support case at all times or case may fall.

6. Casters: Locking
• After case is at desired position (and height),
use level to check that case is level and plumb.
• Readjust height as needed (as instructed in
step #4 above).
• Locking Height: After proper height (and
positioning) of case is attained, tighten the two (2)
set screws to lock each caster’s height in place.
• Locking Movement: Then, to prevent casters’ rolling
capability, lock casters by pressing ON atop the
“ON” and “OFF” lever mechanism (shown at right).
Case will now be secured at its new location.
