Cleaning
4
Hand wash all surfaces of the stretcher with warm water and mild detergent. Dry thoroughly. DO NOT
STEAM CLEAN, PRESSURE WASH, HOSE OFF OR ULTRASONICALLY CLEAN. Using these methods
of cleaning is not recommended and may void this product’s warranty.
In general, when used in those concentrations recommended by the manufacturer, either phenolic type or
quaternary type disinfectants can be used. Iodophor type disinfectants are not recommended for use be-
cause staining may result. The following products have been tested by the Herculite Laboratory and have
been found not to have a harmful effect WHEN USED IN ACCORDANCE WITH MANUFACTURERS REC-
OMMENDED DILUTION.*

Quaternary Germicidal Disinfectants, used as directed, and/or Chlorine Bleach products, typically 5.25% So-
dium Hypochlorite in dilutions ranging between 1 part bleach to 100 parts water, and 2 parts bleach to 100
parts water are not considered mild detergents. These products are corrosive in nature and may cause dam-
age to your stretcher if used improperly. If these types of products are used to clean patient handling equip-
ment, measures must be taken to insure the stretchers are rinsed with clean water and thoroughly dried fol-
lowing cleaning. Failure to properly rinse and dry the stretchers will leave a corrosive residue on the surface
of the stretcher, possibly causing premature corrosion of critical components. Failure to follow the above
directions when using these types of cleaners may void this product’s warranty.
REMOVAL OF IODINE COMPOUNDS
This solution may be used to remove iodine stains from mattress cover surfaces.
1. Use a solution of 1−2 tablespoons Sodium Thiosulfate in a pint of warm water to clean the stained area.
Clean as soon as possible after staining occurs. If stains are not immediately removed, allow solution to
soak or stand on the surface.
2. Rinse surfaces which have been exposed to the solution in clear water before returning bed to service.

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 occur.
Adjustment Procedure:
1. Using a 1/8”hex Allen wrench, adjust the Allen screw located on the latch assembly opposite the latch.
Turning the screw clockwise will DECREASEthe amount of ”play”in the latch. Turning counterclockwise
will INCREASE the amount. 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
cause damage to the latch and/or injury to the patient or user.
