4. The Retractor Arms and the Handrest can be attached to either a Primary Bar or a Floating
Secondary Bar. Position the Retractor Arm or the Handrest where it is needed and tighten
the clamp until there is no movement (Figure 4).
Once the Retractor Arm or the Handrest is in position, tighten the tension-setting knob
to hold it in position. For adjustments to the Retractor Arm or the Handrest, loosen the
tension-setting knob first before moving and then re-tighten.
The Pattie Tray and Retractor Blades are attached to the ends of the Retractor Arms.
CAUTION:
Forcing the Retractor Arms or the Handrest to move against their tightened tension
may cause the cable in the arm to wear and possibly break. The ball joint segments
may become scored and the arm may tend to drift. After a period of time, drifting may
be experienced even though the knob is tight. This is usually due to the drawbar threads
becoming worn, necessitating replacement of the part.
