Figure 5. Swivel Brake
When engaged, the chair swivel brake restricts
rotation of the chair. With the brake released, you
can rotate the chair to any position within approx
imately 30° either side of center. To release the
swivel brake, push the brake lever to the right. To
engage the swivel brake, push the brake lever to
the left.
If the chair swivels left or right with the brake
engaged, or if it is difficult to move with the
brake disengaged, the swivel brake tension must
be adjusted.
Using a 3⁄16-inch hex key, adjust the swivel
brake tension. Turn the adjusting screw clockwise
to increase brake friction. Turn the screw counterclockwise to decrease brake friction.

Double-Articulating Headrest
Figure 6. Double-Articulating Headrest
The double-articulating headrest offers the
widest range of headrest positions possible. A
convenient locking knob allows you to easily
accommodate most patients and procedures.
To position the headrest, release the locking
knob by turning the knob out (counterclockwise),
then adjust the headrest as necessary to fit the
head and neck. Lock the headrest in the desired
position by turning the knob in (clockwise).
To move the headrest higher or lower, simply pull
up or push down on the headrest until it is at the
desired height. (Refer to for Headrest Drift Adjustment
on page 12.)

The headrest can be used to accommodate
wheelchair patients. Slide the headrest up until it
is free from the chair, turn it 180°, then slide it
back into the backrest and push it all the way
down. Run the chair to its full Back Up position.

NOTE
The back cover does not have to be removed to
adjust glide bar tension.
If the headrest drifts downward, or if you find the
headrest difficult to move up or down, the glide bar
tension must be adjusted (see Figure 8). Remove the
headrest glide bar to access the adjusting screw.
Using a Phillips screwdriver, adjust the glide bar
tension. Turn the adjusting screw clockwise three
to four revolutions to increase friction and hold the
headrest more securely. Turn the screw counterclockwise three to four revolutions to decrease
friction and allow the headrest to move up and
down more freely. Reinstall the headrest and
recheck glide bar tension.

Safety Considerations for
Accessory Equipment
The use of accessory equipment not complying with
the equivalent safety requirements of this equipment
may lead to a reduced level of safety of the resulting
system.
Consideration relating to the use of accessory equipment shall include:
Evidence that Safety Certification of the accessory
equipment has been performed in accordance to the
appropriate IEC 601 and IEC 601-1 Harmonized
National Standards.
Transporting the Decade Unit
When transporting the dental unit the chair base
should be fully down, and the chair back should be
fully up. The chair body should be secured to the
chair baseplate. Do not lift the chair by the chair
body.
20
