Resetting the Drawbar to Zero

WARNING:

Reset the drawbar to zero after each use to help prevent drifting of the flexible arms

and damage to the drawbar. Do not store or sterilize the Retractor Arms or the

Handrest while the cable is under tension.

Each Retractor Arm and Handrest is received by the customer with the drawbar at zero

setting: the jointed arm has little or no slack and the drawbar is totally recessed in the well

of the tension-setting knob. The flexible arm is stiffened during surgery by rotating the

tension-setting knob clockwise. The hub of the drawbar will protrude slightly as the cable

is pulled. After much use, the drawbar may begin to protrude excessively (Figures 8 and 9).
