INSTALLATION: CASE REMOVAL (VIA LEVELERS & CASTERS)
Ramp
Skid
Support case
while rolling
down ramp.
2. Remove Case From Skid (Casters)
Remove shipping brackets that secure casters to skid
• Important! Case is shipped with levelers in the
DOWN position (for stability). To prevent damage to
the case, all levelers must be raised ALL THE WAY
UP before moving unit off skid and into position.
• After levelers are raised all the way up, place ramp
up against skid (to allow case to smoothly roll off
from skid).
• Maintain support of case at all times or center of
gravity may cause case to fall.
• Roll unit to rear of skid. Roll down ramp and off skid.
Various Types Of
Case Shipping
Brackets
1. Removing Case Shipping Brackets That Are Attached To Skid
• Remove screws holding Case Shipping Brackets to skid.
• Remove Case Shipping Brackets from Skid.
• See illustrations below. Note: Shipping Brackets will vary in size, shape, material and location
depending upon case type and model.

6
INSTALLATION, CONT’D: POSITIONING & ALIGNING CASE / ADJUSTING LEVELERS
3. Position & Align Alongside Other Cases
• Before adjusting levelers, make certain that the case is in proper position.
• This may require the repositioning of the case you are installing or the already positioned case(s).
4. Adjusting Levelers
• Important! After case is in proper position, levelers must then be LOWERED to floor.
• Adjust levelers so the case is level and plumb.
• You may need to remove front and/or rear toe-kick to access levelers.
• Use adjustable wrench to adjust leveler.
• Depending upon case weight it may be necessary to use a pry bar to accomplish this task.
• Do not use pry bar on toe-kick as it may buckle.
• Do not use pry bar on end panel as it may chip.
• Use pry bar ONLY on base frame to avoid damaging case.
• See illustrations below.
