WARNING / CAUTION / NOTE DEFINITION
The words WARNING, CAUTION and NOTE carry special meanings and should be carefully reviewed.
WARNING
The personal safety of the patient or user may be involved. Disregarding this information could result in injury
to the patient or user.
CAUTION
These instructions point out special procedures or precautions that must be followed to avoid damaging the
equipment.
NOTE
This provides special information to make maintenance easier or important instructions clearer.
WARNING
Patients should be discouraged from sitting directly on the ends of the stretcher. Excessive weight will cause
the litter surface to tip up, possibly causing patient injury.
Always apply the caster brakes when a patient is getting on or off the stretcher. Push on the stretcher to ensure the brakes are securely locked. Always engage the brakes unless the stretcher is being moved. Injury
could result if the stretcher moves while a patient is getting on or off the stretcher.

Cleaning
Clean Velcro AFTER EACH USE. Saturate Velcro with disinfectant and allow disinfectant to evaporate. (Appropriate disinfectant for nylon Velcro should be determined by the hospital.)
In general, when used in those concentrations recommended by the manufacturer, either phenolic type or
quaternary type disinfectants can be used with Staph–Chek fabrics. Iodophor type disinfectants are not recommended for use on Staph–Chek fabrics because staining may result. The following products have been
tested by the Herculite Laboratory and have been found not to have a harmful effect on Staph–Chek fabrics
WHEN USED IN ACCORDANCE WITH MANUFACTURERS RECOMMENDED DILUTION.*

RECOMMENDED
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 damage to your stretcher if used improperly . If these types of products are used to clean Stryker patient handling
equipment, measures must be taken to insure the stretchers are rinsed with clean water and thoroughly dried
following 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

SIDERAIL LATCH ADJUSTMENT
Required Tools:
1/8 Hex Allen Wrench
WARNING
The siderail latch adjustment is pre–set at the factory, and there should not normally be a need for readjustment. If adjustment must be done it is important to follow the procedure below. If it is no t don e pro per ly, injury
to the patient or user 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 Allen screw clockwise will DECREASE the amount of ”play” in the latching mechanism. Turn-
ing 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
cause damage to the latch and/or injury to the patient or user.
