SIDERAIL LATCH ADJUSTMENT
Required Tools:
1/8 Hex Allen Wrench
WARNING
The siderail latch adjustment is pre–set at the factory, and should not normally need adjustment. If adjustment
must be done, it is important to follow the procedure below. If it is not done properly, injury could occur.
Adjustment Procedure:
1. Using a 1/8 hex Allen wrench, adjust the hex Allen screw located on the latch assembly opposite the latch.
Turning the screw clockwise will
DECREASE
the amount of ”play” in the latching mechanism. Turning
counterclockwise will
INCREASE
the amount.
NOTE
The amount of ”play” in the siderail, when in full up engaged position, should be approximately 1/8 to 3/16”.
CAUTION
Too much ”play” when the siderail is in the full up engaged position will give the siderail the appearance of
being unstable and could also cause premature wearing of the latch system.
Too little ”play” will obstruct the latch and keep it from engaging completely in the full up position, which may
cause damage to the latch and/or injury to the patient or user.
