Wall Mount Adjustments
Leveling
6
Your wall-mounted unit is leveled during
installation and should not require adjustment.
However, if the unit needs to be leveled, the
following procedures will help you.
Leveling Front-To-Back:
Two leveling setscrews are supplied with the unit.
These will be either in the top or bottom leveling
screw holes (see Figure 6).
If the unit tilts forward from the wall (see Figure 6A),
1. Place a leveling device on the work surface.
2. Loosen the bottom two mounting screws.
3. Install the leveling setscrews in the bottom two
holes, then tighten them until the unit is level.
4. Retighten the mounting screws.
Cascade 2615 Cart / Cascade 3175 Wall Mount
If the unit tilts toward the wall (see Figure 6B):
1. Place a leveling device on the work surface.
2. Loosen the top two mounting screws.
3. Place the leveling setscrews in the top two
holes, then tighten until the unit is level.
4. Retighten the mounting screws.

2. Place a leveling device on the work surface.
3. Using a 3⁄4" open-end wrench, gently turn the
leveling cam (see Figure 6) until the unit is level.
4. Retighten the mounting screws.

Arm Spring Tension
When you move the unit, it should stay where
you place it. If the unit tends to drift up or down,
the tension of the arm’s internal spring needs to
be adjusted.
NOTE
The spring tension should be adjusted with a
“normal” load on the work surface. The brake
on/off toggle should be in the OFF position.
1. Locate the adjustment screw under the arm
(see Figure 7).
1/4" HEX KEY
Figure 7. Arm Spring Tension Adjustment
2. Use a 1⁄4" hex key to make the adjustment.
• If the unit drifts down, turn the screw
clockwise to increase spring tension.
• If the unit drifts up, turn the screw
counterclockwise to decrease spring tension.

Cascade 2615 Cart / Cascade 3175 Wall Mount
Arm Brake Adjustment
NOTE
Adjust arm spring tension prior to arm brake
adjustment (refer to page 8). Retest the brake
after spring adjustment.
The air-actuated arm brake on your wallmounted unit has been set at the factory and
should not need further adjustment. If the
brake does not hold, first check to be sure that
the brake on/off toggle is in the ON position,
and that there is air (at least 60 psi) to the unit.
Refer to your Floor Box Owner’s Guide (A-dec Publication No. 85.2611.00) for complete
air pressure adjustment procedures.
If the brake will not hold, the brake may be
too loose. A brake which is too tight will cause
a screeching or scraping noise as you move the
unit up or down when the brake is not on.
To adjust the brake:
1. Move the brake on/off toggle to the OFF position.
2. Remove the plug from the access hole on the
left side of the arm (see Figure 8).

NOTE
Adjust the nut in small increments and retest

the adjustment nut may damage the brake.
4. Locate the adjustment nut under the arm
(see Figure 9).
• To tighten the brake, use a 7/16" open-end wrench
to hold the adjustment nut while you turn the
hex key clockwise
• To loosen the brake, use a 7/16" open-end wrench
to hold the adjustment nut while you turn the
hex key counterclockwise.

Cart Adjustments
Work Surface Height
WARNING
The cart is very heavy. Cart height adjustment requires two people to safely complete.
Firmly tighten the knob after adjusting the
cart height, serious bodily injury may result
if the knob is not secure.
1. Securely hold the cart top so it will not drop,
loosen the knob.
Figure 10. Cart Height Adjustment
2. Lift or lower the cart top until the work surface
is at the desired height.
3. Firmly tighten the knob. If the top lowers, the
knob was not tightened enough.

Work Surface Leveling
To level your assistant’s unit work surface:
1. Place a leveling device on the work surface.
2.Check for level front-to-back and side-to-side.
3.Locate the four mounting screws found in the
leveling plate on the underside of the work
surface (see Figure 12). Using a 3⁄16" hex key,

4. Locate the four leveling setscrews
(there is one in each corner of the leveling
plate underneath the unit work surface).
Front-to Back Leveling:
Face the work surface handle.
If the work surface tilts toward you, use a 3⁄16" hex
key and tighten the two leveling setscrews closest
to you until the work surface is level.
If the work surface tilts away from you, tighten the
two leveling setscrews furthest away until the
work surface is level.
Side-to-Side Leveling:
Face the work surface handle.
If the work surface tilts to the left, tighten the two
leveling setscrews on the left side of the leveling
plate until the work surface is level.
If the work surface tilts to the right, tighten the two
leveling setscrews on the right side of the leveling
plate until the work surface is level.
5. When you have completed these steps tighten
the four mounting screws, then check the work
surface again for level.
