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
Always apply the caster brakes when a patient is getting on or off the Stretcher Chair. Push on the Stretcher
Chair to ensure the brakes are securely locked. Always engage the brakes unless the Stretcher Chair is being
moved. Injury could result if the Stretcher Chair moves while a patient is getting on or off the Stretcher Chair.

Cleaning
5
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 with Staph–Chek fabrics. Iodophor type disinfectants are not rec-
ommended 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.*

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.

JACK DESCENT RATE ADJUSTMENT
Required Tools:
Bungee Cords
Adjustment Procedure:
1. Pump the litter up to full height
2. Lift the base hood, separating the Velcro holding it to the base frame.
3. The adjustable descent valve is located on the base of the jack and has a blue knob on the end. To adjust,
loosen the silver locking ring by turning it counterclockwise. Turning the blue knob clockwise will increase
the rate of litter descent. Turning it counterclockwise will decrease the rate of descent.
4. Adjust the valve so that the jack at the foot end of the Stretcher Chair will descend slightly faster than
the jack at the head end.
5. Remove the bungee cords supporting the base hood and secure the hood to the base frame.
NOTE
The jack descent rate was preset at the factory to drop the foot end 3–7 seconds faster than the head. It is
recommended that the foot drops faster to avoid patient disorientation.
STEERLOCK SPRING REPLACEMENT
Required Tools:
3/32”Hex Allen Wrench 11/32”Wrench
Bungee Cords Pliers
Replacement Procedure:
1. Raise the litter to full–up.
2. Lift up the plastic base hood, separating the Velcro holding it to the base frame and, using the bungee
cords, suspend it from the litter.
3. Using a 3/32”hex Allen wrench and a 11/32”wrench, remove the 8–32 fastener, washer and nut holding
the steerlock arm onto the base.
4. Holding onto the extension spring, twist the steerlock arm back and forth to remove it from the spring.
5. Using pliers, remove the spring from the steerlock weldment over the caster and discard it.
6. Grease the end of the steerlock weldment and install the replacement extension spring onto it until the
spring reaches the bend in the steerlock weldment arm.
7. Grease the end of the steerlock arm and, while holding the extension spring, insert the steerlock arm into
the spring until it reaches the bend in the steerlock arm (rotating the steerlock arm while pushing on it
may help).
8. Reconnect the steerlock arm to the base with the 8–32 fastener, washer, and nylon lock nut and tighten.
9. Actuate the brake steer pedal and ensure the steerlock latch engages into the notch in the locking caster.

BRAKE/STEER PEDAL REPLACEMENT
Required Tools:
Two (2) 7/16”Wrenches 3/16”Drive Pin Loctite 409 or Equivalent
Hammer 3/8”Box End Wrench Bungee Cords
Replacement Procedure:
NOTE
It may require two people to safely perform this procedure.
1. Apply the brakes, if possible, with the remaining good brake/steer pedal. If this is not possible, have
someone assist you with the following: Using a large wrench or pry tool, push down on the brake bar
(compressing the spring) and manually move the molded plastic brake cam over to the brake position
at both ends of the base.
2. Raise the litter to full up. Raise the Fowler and the siderails.
3. Suspend the base hood from the litter and out of the way with bungee cords. Or, for better access, re-
move the litter by following the next 3 steps.
4. Using a 3/8”wrench, remove the bolt in the litter support tube above the black bellows on both ends.
5. With the assistance of another person, lift off the stretcher litter and set it aside, taking care not to damage
the leg section linkages, or other litter components.
6. Lift off the plastic base hood, separating the Velcro holding it to the base frame.
7. Using the 7/16”wrenches, remove the bolt, nut and washers holding the square brake drive link assembly
on the brake actuator on both sides of the base.
8. While lifting one end (head or foot) of the base, rotate the brake/steer pedal so its bottom is facing up.
9. Use a hammer and 3/16”drive pin to remove the groove pin (part number 26–261) from the plastic brake/
steer pedal (part number 715–201–201). Be sure that you are driving the pin out from the bottom of the
pedal towards the top of the pedal.
10. Once the groove pin has been removed, remove the brake/steer pedal from the brake rod (use of a ham-
mer may be required).
11. Repeat step 8 so the brake actuators are upright.
12. Fit the replacement brake/steer pedal onto the brake rod.
13. Align the holes in the brake/steer pedal with the holes in the brake rod and use a hammer to install the
replacement groove pin. Drive the pin in from the top of the pedal until it is flush to the top of the pedal.
14. Reverse step 7 to reattach both brake drive link assemblies to the base (When the pedal is reconnected
it will already be in the brake position).
15. Actuate the brake/steer pedal to ensure the unit functions fully in brake, neutral and steer modes.
16. Reinstall the base hood, securing it to the Velcro.
17. With the assistance of another person, place the litter back on the base (if necessary).
18. Use a 3/8”wrench to install the bolts in the litter support tubes above the black bellows on both ends of
the litter.
