Service Information

PNEUMATIC FOWLER ADJUSTMENT

Required Tools:

5/32” Hex Allen Wrench 1/2” Open End Wrench

1. Refer to the pneumatic Fowler assembly drawing on page 44 for parts reference.

2. For easier access, raise the Fowler to 75 or higher.

3. Using a 1/2” open end wrench, loosen the hex nuts (item E) in the actuator arms on the end of the trip
bar (item M).

4. To adjust the Fowler, use a 5/32” hex Allen wrench to turn the Allen screws (item J) 1 to 2 turns count­er−clockwise if the Fowler will not move or 1 to 2 turns clockwise if the Fowler will not hold its position.

5. Retighten the hex nuts. Be sure the Fowler travels from flat up to 90 and down again and holds its posi­tion when weight is applied before returning the stretcher to service.

FOLDDOWN SIDERAIL LATCH ADJUSTMENT

Required Tools:

1/8” Hex Allen Wrench

WARNING

The siderail latches are preset at the factory, and do not normally need adjustment. If adjustment must be
done, it is important to follow the procedure below. If adjustment is not done properly, injury to the patient
or user could result.

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
inches.

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
result in damage to the latch and/or injury to the patient or user.
