ASSEMBLY Q CRANK TABLE BASE
STEP 1
With the table top facing down on a soft, clean surface, arrange the cross channels and top supports
as shown.
• Positioning does not need to be exact
at this time.
• Mounting tabs on cross channels face
inward, toward each other.
• Holes on the top supports are offset
to the rear.
STEP 2
Use a 5mm Allen key to loosen the M10 set screws on the
cross channels (two on each side of center).
STEP 3
Adjust the cross channels to their approximate nal
lengths, as shown.
• Center the inner piece in each cross channel.
STEP 4
Attach the side legs to the cross channels and top
supports with six M8x12 screws per leg.
• Use a 5mm Allen key.
• Two screws attach to each cross channel and
two screws attach to the top supports.

STEP 5
Attach a foot plate and foot to each of the side legs
with the M6x35 screws.
• First, place the foot plate onto the leg with the
smooth side up.
• Position the foot over the foot plate, as shown.
The short side of each foot should face the rear.
• Screw the foot securely in position using a 5mm
Allen key.
STEP 6
Adjust the position of the frame before screwing
it to the table.
• The top supports on each side should be
approximately 1" (25mm) from the ends of
the table.
• The rear of the feet should align with the rear
of the table.
STEP 7
Once in their nal position, attach the top
supports and cross channels to the table.
• Use ST4.8x19 screws (8 total required).
• Attach the screws through the mounting
tabs on the cross channels and through
the holes at the ends of the two top
supports.
STEP8
Tighten the M10 set screws in the cross
channels (8 total). Use the 5mm Allen key
to hand tighten.

STEP 9
Use a 2mm Allen key to loosen the set screws
on each end of the gear connector’s outer
cylinder.
• This will allow you to adjust the length of the gear
connector shaft so that you can insert the shaft into
gear drive of the two legs.
STEP 10
Center the outer cylinder of the gear connector
between the two legs. Then extend the inner shaft
on each side to insert the ends into the gear drive.
• Fully insert the shaft ends until they reach
the stop.
• After inserting the shaft, tighten the set screw
at each end.
• Check that the gear connector is securely
installed. There should be minimal play from
side to side.
STEP11
Prepare to install the crank handle by
loosening the set screw in the outer cylinder.
• The inner shaft of the handle is
available in three lengths: 7" (17.8 cm),
10½" (26.7 cm), and 14" (35.6 cm).
• The 7" shaft is pre-installed. The other
shafts may be substituted if table width
requires (see next step).
STEP12
Position the shaft and crank handle. The
handle may be installed on either the
left or right side of the table.
• Fold the crank handle as shown.
• Insert the shaft through the hole in the
cross channel to engage it into the
gear drive in the base of the leg.
• Choose the correct shaft length so
that there is 23/16" (55 mm) between
the edge of the table and the outer
edge of the crank handle gearbox.
• A minimum shaft length of 1" (25mm)
must remain in the outer cylinder.

STEP 13
Complete crank handle installation.
• Attach the crank handle gearbox with four
ST4.8x38 screws.
• Attach the crank handle bracket with two
ST2.9x19 screws. The bracket holds the handle
under the table when not in use.
• Check that the shaft is fully inserted against the
stop inside the base of the leg. Then tighten the
set screw on the outer cylinder.
STEP 14
With the assistance of a helper, turn the table
IMPORTANT: There must be 1" (25mm) of
clearance on all sides of the work surface
(and other moving parts) to ensure free,
unobstructed movement.
• Adjust the leveling glides on the feet
to level the work surface, if necessary.
STEP 15
Move the crank handle to its operating
position and test operation.
• Turning the handle clockwise raises the table.
Turning the handle counter-clockwise lowers it.
• If there are problems with operation, check
that all shaft ends are securely inserted. If
problems continue, call ESI Customer Service.

OPERATION
When not in use, the crank handle is typically
hidden under the work surface, held in place by
the crank handle bracket.
To use the crank to operate the table, pull
the handle out slightly and rotate it 90° to its
operating position.
Turn the handle clockwise to raise the table.
Turn the handle counter-clockwise to lower the
table.
Always position the handle under the table when
not in use to avoid accidental contact. Pull the
handle out slightly and “fold” it under the the
table. Push in the handle to secure it in the crank
handle bracket.
