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
5
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

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 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
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.

HYDRAULIC TROUBLESHOOTING
Be sure the pedal linkage has been adjusted properly before beginning service on the jacks (see page 9).
PROBLEM/SYMPTOM SOLUTION
Jack will not raise to full height. Add hydraulic fluid (see p.13). Check for leaks.
Jack will not hold in raised position. Close the needle valve completely. If the jack
holds, replace the release valve (see p.15).
Jack will not pump up and the jack actuator rod
does not move. Close the needle valve. If the jack will now pump
up, replace the release valve (see p.15). If the jack
still will not pump up after closing the needle valve,
replace the poppet valve (see p. 15).
Jack will not pump up but the jack actuator rod
does move when the pump pedal is activated. Replace the check valve (see p. 14).
Jack will not pump up and the jack actuator rod
may or may not move. Remove excess air (vacuum) in system (see be- low).
Contact Stryker technical service at 1–800–327–0770 for further assistance.
REMOVAL OF EXCESS AIR (VACUUM) FROM THE HYDRAULIC SYSTEM
Procedure:
1. Verify all hydraulic linkages are secure and operating properly (see pedal linkage adjustment procedure
page 9).
2. Using pump pedal, actuate system several times. This will force the air through the system and the jack
should now pump up.

CHECKING HYDRAULIC FLUID LEVEL
Required Tools:
3/8 Open End Wrench 3/4 Open End Wrench
Procedure:
WARNING
To avoid personal injury or damage to the stretcher, remove the litter and the base hood before beginning
service on the jacks.
1. Using a 3/8 open end wrench, remove square head set screws from both head and foot end jack support
tubes. Remove litter top and set aside.
2. Lift base hood off base frame and set aside.
3. Be sure there are no hydraulic leaks. If there are, jack replacement will be necessary.
4. Lower the jack to the full down position.
5. Using a 3/4 open end wrench, slowly turn the fill plug located on the side of the reservoir counterclockwise
to allow excess system pressure to vent. Remove the fill plug.
6. The hydraulic fluid should be visible at the bottom of the fill hole. If it is not, add Mobil Aero HFA hydraulic
fluid (Stryker part number 2020–70–475) until the fluid is visible at the bottom of the fill hole. Replace the
fill plug.
CAUTION
Use of other types of oil may damage hydraulic units.
7. Replace the hood and the litter.
JACK DESCENT RATE ADJUSTMENT
Required Tools:
Screwdriver Bungee Cords (or equivalent)
Adjustment Procedure:
1. Pump the litter up to full height.
2. Lift the base hood, separating the hood from the base frame. Using the bungee cords, support the base
hood.
3. The descent rate needle valve is located on the base of the jack. Turning the needle valve clockwise, with
a screwdriver, will decrease the rate of descent. Turning it counterclockwise will increase the rate of de-
scent.
4. Adjust the needle valve so that the foot end of the stretcher descends slightly faster than the head end.
NOTE
The larger percentage of a patient’s weight is located in the torso area. Adjust descent rate accordingly.
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 faster than the head. It is recommended
that the foot drop faster to avoid patient disorientation.
