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 en-
sure 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
4.1
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.
Clean Velcro AFTER EACH USE. Saturate Velcro with disinfectant and allow disinfectant to evaporate. (Ap-
propriate 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. Iodophor type disinfectants are not recommended. The following
products have been tested and have been found not to have a harmful effect WHEN USED IN ACCOR-
DANCE WITH MANUFACTURERS 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 cor-
rosive residue on the surface of the stretcher, possibly causing premature corrosion of critical components.
NOTE
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 and foam footrest pad 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.

Service Information
PNEUMATIC FOWLER ADJUSTMENT
Required Tools:
5/32”Hex Allen Wrench 1/2”Open End Wrench
Adjustment Procedure:
1. Refer to drawings 1210–31–120 or 1710–31–120 (Pneumatic Fowler Assembly, page 45 or page 47) for
parts reference.
2. For easier access, move Fowler to 75 degrees or higher.
3. Using a 1/2”open end wrench, loosen the nuts (item K) in the actuator arms on the end of the trip bar (F).
4. To adjust the Fowler, use a 5/32”hex Allen wrench to turn the Allen screws (item N) 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 nuts. Be sure the Fowler will travel from flat to 90_and down again and will hold its position
when weight is applied before returning the stretcher to service.
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 readjust-
ment. If adjustment must be done it is important to follow the procedure below. If it is not done properly, 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 DECREASEthe 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.

Adjustment Procedure:
1. Pump the litter up to full height.
2. Lift the base hood, separating the hood from the base frame. Using the wooden blocks, support the base
hood.
3. To adjust the foot end descent pedal, use a 5/32 hex Allen wrench to loosen the set screw (C) in the stop
collar (D) on the release rod. Hold the pedal parallel to the floor and slide the collar up to the bracket on
the release rod. Tighten the set screw on the stop collar. Be sure the head end and foot end descent
pedals are level with each other. Repeat for the head end pedal, if necessary.
4. Once the pedals are level, be sure the paddle on the end of the release rod for the foot end jack is slightly
touching the actuating stem on the jack base. If it is not, use a 3/32 hex Allen wrench to loosen the set
screw on the paddle hub. Adjust the paddle to JUST touch the stem of the jack. Tighten the set screw
in the paddle hub. Repeat for the head end jack, if necessary.
5. Depress the pedal for the foot end jack. The jack should start to descend about the same time the paddle
on the end of the rod contacts the sleeve on the jack actuating stem. The bracket on the foot pedal body
should hit the stop screw (B). Any further movement could cause damage to the stem components inside
the jack housing. To adjust the stop screw, use a 1/2 open end wrench to loosen the hex jam nut (A).
Turn the screw and re–tighten the hex jam nut. Repeat for the head end jack.
6. Pump the litter up to full height.
7. Step on both descent pedals at the same time. Both ends of the litter should lower with the foot end lower-
ing slightly faster than the head end. If it does not, refer to the procedure for adjusting the jack descent
rate.
8. Remove the wooden blocks supporting the base hood. Use the pedal cut–outs on the side of the hood
as a guide for proper re–positioning.
