Note: For Basic Assembly Instructions to the D4 Bench please use the D4 Assembly Instructions
included with your shipment. Before starting the assembly of the bench you must decide on the
desired starting height of the worksurface. The starting height will be used to establish the
location of many components of the adjustable height system and other bench options such as
electrical channels, shelving, footrests and suspended cabinets. When determining adjustment
height range of the worksurface, consider the height location of options such as electrical outlets

4
in the uprights. Some bench uprights have electrical outlets at 42" from the floor and interconnect
cables from upright to upright under the worksurface that could be damaged if the adjustable
range is not set correctly. If a higher starting height is needed you may need to make
modifications to your worksurface to avoid the outlets and power cords that may be plugged in
while the bench is in use. If a lower starting height is needed be sure to check that interconnect
cables are not affected bay any of the adjustable height system components. After assembly is
complete, test the movement of the system to be sure the outlets, power cords and interconnects
will not be damaged.
STEP 1: Locate basic bench hardware kit HWR214 for SINGLE SIDED. Locate the hardware kit
for the adjustable height unit. Use hardware kit HWR297.
STEP 2: Assemble the 2 uprights of the bench to the rear modesty panel as shown in Figure 2
below using 5/16-18 x .75 square head bolts, 5/16 flat washers and 5/16 hex keps nuts. The top
of the modesty panel must be placed 2.5" below the planed starting height of the top of the
worksurface. The floor glides in the bases of the uprights must be set so the uprights are parallel
to each other in both front to back and side to side. This alignment will make the rest of the
assembly go much smoother.
Important Installation Note:
If the bench has a standard or flip-up ergonomic footrest, the footrest brackets need to be
installed onto the uprights before mounting the cylinder support brackets shown in figure 3 on
page 5, item #2. For footrest assembly instructions refer to the Dimension 4 bench assembly
instructions.

STEP 3: The location of the bottom of the cylinder support brackets for a 30” worksurface starting
height is 7.5” from the floor. If your starting height is more or less than 30” add or subtract the
difference in starting height to or from 7.5” to locate the cylinder support brackets on the uprights.
EXAMPLE: for a worksurface starting height of 28" subtract 2" from 7.5" and set the brackets at
5.5” from the floor. Attach the cylinder support brackets shown in Figure 3 item #2, to the uprights
using 5/16-18 x .75 square head bolts, 1/4 flat washers, and 5/16 hex keps nuts and tighten the
nuts. DO NOT OVER TIGHTEN.
Figure 3
STEP 4: Remove the extruded guide assemblies, item 3 shown in Figure 3, from the worksurface
support assemblies’ item 1 shown in Figure 1 on page 3. Attach the extruded guide assemblies to
the uprights using 5/16-18 square head bolts, 1/4 flat washers, and 5/16-18 keps nuts. Slide the
guide assembly down to the top of the cylinder support bracket and tighten the nuts. DO NOT
OVER TIGHTEN.
STEP 5: To attach the worksurface support assemblies item 1 of Figure 4 position the motor
housing assembly between the bench uprights in front of the modesty panel. Plug the power cord
of the motor housing assembly into a 115 VAC power source. Using the motor switch turn the
motor system on in the UP direction so that the cylinder shafts extends approximately 8” out of
the cylinder housing. Being careful not to damage the hydraulic lines carefully align the

6
worksurface support assemblies extruded aluminum runners shown in Figure 4 over the guide
assembly attached to the uprights. Feed the end of the cylinder shaft into mounting hole in the
cylinder support bracket as shown. Attach the cylinder shaft to the cylinder support bracket
using10-32 x 1.00 phillips machine screw, #10 flat washers and 10-23 hex keps nuts as shown in
Figure 4. Tighten nuts. Repeat this for both sides of bench. DO NOT LOWER the pump system at
this time.
Figure 4
STEP 6: Attach the rear guard panel assembly item 4 Figure 5 to the back of the worksurface
support assemblies item 1 Figure 5 using 1/4-20 x .75 hex head bolts item E and 1/4 flat washers
item M as shown in Figure 5. DO NOT tighten this hardware. At this time lower the worksurface
support assemblies to check to make sure they are fitted correctly. To do this apply weight or
pressure to the top of both worksurface support assemblies and using the motor power switch
turn the motor on in the DOWN direction. Lower the worksurface support assemblies to the
bottom of their adjustment range. DO NOT turn the motor on in the down position without
applying weight or pressure to the top of the worksurface support assemblies as this will cause
damage to the hydraulic cylinders. Once lowered lift up and then push down gently on the front of
the worksurface support assemblies to feel for movement in the system. There should be very

7
little movement of the worksurface support assemblies. If there is too much movement please see
page 12 for instructions on making adjustments to remove the movement. Once any adjustments
needed have been made attach the cylinder outer covers items 6 and 7 shown in Figure 5 using
#10-32 x .50 phillips screws item D and #10 flat washers item N. Carefully align the cylinder
covers so that they are in line with the worksurface support assemblies and tighten these screws.
Using the motor power switch raise the worksurface support assemblies approximately 8” out of
the cylinder housing.

STEP 7: Being careful not to damage the hydraulic lines lift the motor housing assembly and
attach it to the back of the rear guard panel using 1/4–20 x .75 hex head bolts and 1/4 washers
through the front of the rear guard panel into the inserts in the motor housing assembly. Align the
top of the motor housing assembly so that its top flange is flush with the top flange of the rear
guard panel and tighten the hardware. Carefully organize the hydraulic lines, switch cord and
power cord so that they will not be damaged when the worksurface is attached.
Figure 6
STEP 8: Assemble the worksurface hat sections to the underside of the worksurface as
instructed in the D4 Assembly Instructions. Set the worksurface onto the worksurface support
assemblies as shown in Figure 7 sliding it back between the bench uprights carefully so that is
sits on top of the rear guard panel. Align the inserts in the underside of the worksurface with the
slots in the worksurface support assemblies and the rear guard panel and thread the 1/4-20 x .75
hex head bolts item E and1/4 flat washers item M into the inserts in the worksurface. DO NOT
TIGHTEN hardware at this time.
Figure 7
STEP 9: The bench frame must be squared, leveled and the worksurface centered between the
uprights making sure the gap between the side worksurface cutouts and the uprights is equal.
The gap between the front of the worksurface cutout and the front of the upright should be 1/16 of
an inch minimum. Once the worksurface is in place all worksurface and rear guard panel

9
mounting hardware must be tightened, being careful not to over tighten the bolts that go into the
worksurface. Using the motor power switch lower the worksurface to it’s lowest point making sure
the outer cylinder covers do not interfere with the worksurface hat sections and that all hydraulic
lines are not pinched or kinked in any way as this will cause damage to the hydraulic system.
Figure 8
STEP 10: Select the side of the bench you want the motor power switch mounted and attach the
motor switch bracket item T first using 2 1/4-20 x .500 square head bolts item D and 2 1/4-20 nuts
item H to the worksurface hat section by feeding the screws through the switch bracket and
loosely threading the nut onto the bolts. Slide the head of the Sq. Head bolt into the slot at the
end of the front worksurface hat section and position as needed. Tighten the hardware being
careful not to over tighten. Remove the pre-installed screws on the bracket and feed them
through the body of the motor control switch. Do not over tighten. Once all hardware is tightened
raise and lower the worksurface through it’s full adjustment range a few times making sure it
moves smoothly and that the hydraulic lines are not crimped or pinched in anyway and there are
no interferences between the frame parts. If the worksurface does not raise and lower at the
same rate on each end of the worksurface you may need to realign the worksurface mounting. To
do this lower the worksurface to its lowest point, loosen all mounting hardware and realign the
worksurface as described in step 7. Once realigning is complete tighten the hardware and test the
adjustment range again. If the problem persists please contact your factory representative or the
factory.

10
STEP 11: The hydraulic lines must be attached to the underside of the worksurface to prevent
them from being damaged. It is best to coil these lines to take up the slack and then position them
in places where they will not get pinched or crushed, such as between or behind the worksurface
hat sections, drawers or other accessories.
Using the motor power switch raise the worksurface to its highest point. Attach the plastic zip tie
holders item P to the underside of the worksurface in places where the hydraulic lines can move
freely but are out of the way using the #6 x .50 Phillips screws item C. Feed the zip ties item R
into the zip tie holders. Carefully coil the hydraulic lines, position them into the zip tie holders and
attach them using the zip ties. Gently tighten the zip ties around the hydraulic lines being careful
not to create any stress between the hydraulic lines and the cylinder fittings.
Moving the Completed Workstation:
When moving the workstation DO NOT lift workstation by the worksurface by hand or by forklift
device. This will cause severe damage to the hydraulic system and void the manufacturer’s
warranty. The workstation must be lifted by the uprights and upright bases only and transported
using furniture dollies of some kind. When the bench is in position it must be squared and leveled
before it is placed in use. Test the operation of the workstation several times to be sure it moves
freely throughout its adjustment range.

Adjusting Worksurface Support Assemblies
PLEASE NOTE: It is very important that you read through and understand all the instructions
below before making any adjustments to the worksurface support assemblies. If you need
assistance please contact IAC Industries customer service at 800-989-1422.
STEP 1: Lower the motorized system to its lowest point. Remove the inner cylinder cover from
the worksurface support assembly that you are adjusting. Loosen the five nuts “A” at the rear
edge of the worksurface support bracket as shown below with a 7/16” wrench. Loosen only 1/4 of
a turn. DO NOT over loosen or remove these nuts.
STEP 2: Locate the three guide adjustment set screws “B” found at the back of the worksurface
support assembly as shown. Using a 3/32” Allen wrench turn the set screw clockwise gently to
tighten the two (2) set screws found at the top and middle of the worksurface support assembly.
DO NOT over tighten. Raise the motorized system the minimum amount required to expose the
lowest set screw. Gently tighten this set screw. DO NOT OVER TIGHTEN THE SET SCREWS.
STEP3: When all three (3) set screws have been adjusted retighten the five nuts that were
lessened in Step 1. NOTE: these nuts are lock type so they do not need to be over tightened,
however it is important that they are tightened enough to hold the guild runner in place.
STEP 4: After making adjustments to the worksurface support assemblies that require it run the
motor system up and down through its entire adjustment range to make sure it moves freely and
does not bind. If it does not move freely the adjustments made are too tight. Lower the system to
its lowest point and readjust the set screw following the steps above. Once satisfied that the
system is adjusted correctly reattach the inner cover and return to page 7.
