Before attaching tabletop to base, use brake lever to lock
the upper structure in a position similar to Figure 5.
Lift tabletop and place on supports with front edge resting
on the tabletop lips as shown in Figure 5. This step requires
2 people to ensure tabletop does not fall to the floor.

Attach Tabletop
Center tabletop from left to right, as shown in Figure 6.
Using tabletop screws (E), attach tabletop to supports as
shown in Figure 7. For best results it is recommended that
holes be started with an awl or drill. Use great care not to
drill all the way through board.

Table base is spring-loaded and great care must be taken in
the following steps to avoid injury. Read instructions all the
way through before proceeding.
Be sure you are standing behind the table, as shown in
Figure 3, and all other persons are standing clear.
Be sure brake lever is in the locked position, as shown in
Figure 3.
Figure 3 Figure 4
While standing behind the table, cut the restraining cord.
The frame should not spring up when doing this because
it is being held in place by the brake lever.
While still standing behind the table, place right hand
on the crossbar as shown in Figure 3. Grasp firmly and
prepare for the bar to spring upward. Keep your head and
upper body back. Do not lean over table.
With left hand, slowly release the brake lever as shown in
Figure 4. Use your right hand to guide and control the
upward movement of the crossbar. Once brake lever
is fully released, the upper structure of the table frame
should come to rest.

Release brake lever on right side of table. This allows both
springs to return to their natural, relaxed positions.
Using the Allen wrench provided (G, 5mm), tighten the Tilt
Adjustment Bolt to increase the tilt strength or loosen the
Tilt Adjustment Bolt to reduce the tilt strength as shown in
Figure 11. This procedure will take some trial and error to
reach the desired spring tension.
The tabletop should tilt gently from the horizontal position
to the near-vertical position when the brake lever is released.
If it tilts too quickly or fails to tilt completely, adjust the Tilt
Control Spring as follows.

Release brake lever on right side of table. This allows both
springs to return to their natural, relaxed positions.
Elevate the left foot to gain access to the Lift Adjustment Nut
as shown in Figure 10.
Using the wrench provided (F, 17mm), tighten the Lift
Adjustment Nut to increase the lift strength or loosen
the Lift Adjustment Nut to reduce the lift strength. This
procedure will take some trial and error to reach the
desired spring tension.
The tabletop should rise gently to its uppermost position
when the brake lever is released. If it rises too quickly or fails
to rise completely, adjust the Lift Control Spring as follows.

Lift-Strength Adjustment
Figure 10
The Ensign table is designed to accommodate a variety of tabletop
sizes and weights. For best results, it is likely you will have to make
spring and tension adjustments before using your table.
There are 2 springs that control the functions of the Ensign table:
1. The spring inside the left leg controls the lift strength
2. The spring under the tabletop controls the tilt strength
Please refer to Figure 8 and Figure 9.

Release the brake lever
Loosen the outer nut, A, a few turns.
(No need to remove all the way)
Tighten inner nut, B, one revolution
Return brake lever to the locked position and test to see if
tabletop holds firmly in desired position. If not, release brake
and tighten nut B additional revolution(s). This procedure will
take some trial and error.
Once desired brake-locking strength is reached, tighten nut
A firmly up against nut B. Use care not to rotate nut B while
doing so.
The brake lever should hold the tabletop firmly at any height
or tilt position. If it fails to do so, follow this procedure to
increase the braking strength. Please refer to Figure 12.

After extended table usage, the brake-lock strength will gradually
diminish and it will be necessary to repeat this procedure.
