DROP OPERATION AND TENSION SETTING
1. Advise your patient prior to setting the tension.
2. With the patient on the table, cock the drop section with an upward motion of the cocking lever. There must be sufficient
tension on the drop to hold the patient's head or body weight.
3. Decrease the tension control knob by turning it counter-clockwise until the section drops.
4. Increase the tension by turning the tension control knob clockwise 3-4 half turns. As a general rule, the drop is now
set for the patient's weight, which may vary according to the practitioner's preference.

Headpiece & Table Operation

MAXIMIZING FACIAL COMFORT
For patients sensitive to pressure on the eyes, slightly raise the
back end of the headpiece. This will take pressure off of the
eyes, supporting the weight of the head at the mandible and
zygomatic arches. This maneuver, in combination with slight
flexing of the headpiece, will provide optimal facial comfort for
some patients.
Knob pushed in BEFORE cocking
The drops on the headpiece and table have adjustable tension and cock with an upward movement of the cocking lever.
Following is a general guideline for setting the tension.
PRIOR to cocking the headpiece, set for straight drop by pulling
out the headpiece straight drop/forward motion knob until you
feel it is “set” into position. This will be just short of coming
into contact with the cocking bar. If you pull the knob out too
far, simply push it back in.
PRIOR to cocking the headpiece, set for forward motion drop
by pushing in the headpiece straight drop/forward motion knob.
Cock the headpiece with an upward motion on the headpiece cocking lever.
Please note: Be sure to change the headpiece drop function
before cocking the headpiece to prevent an ineffective drop and
damage to the drop mechanism.
Set the desired tension by turning the tension control knob clockwise (increasing tension) or counterclockwise (decreasing tension).
WEIGHTS FOR BACK LEGS
Place weights on the crosspiece of the back legs for counterbalance.
