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.

Preventive Maintenance
5
CLEANING
1. Hand wash all surfaces of the stretcher with warm water and mild detergent. Dry thoroughly.
2. 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.)
NOTE
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.

PNEUMATIC FOWLER ADJUSTMENT (OUTSIDE MOUNTED CYLINDERS)
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 56 or page 58) 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.

Service Information
FOLDDOWN SIDERAIL LATCH ADJUSTMENT (1210 or 1710)
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 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.

Service Information
HYDRAULIC SYSTEM TROUBLESHOOTING
NOTE
Be sure the pedal linkage has been adjusted properly before beginning service on the jacks (see page 10).
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 valve #1 (see p. 14). If the jack
does not hold, replace valve #2 (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 valve #1. If the jack still will not pump
up after closing the needle valve, replace valve #3
(see p. 15).
Jack will not pump up but the jack actuator rod
does move when the pump pedal is activated. Replace valve #2 (see p. 15).
Jack will not pump up and the jack actuator rod
may or may not move. Remove excess air (vacuum) in system (see p. 13).
Contact Stryker technical service at 1–800–327–0770 for further assistance.

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 wooden blocks, support the base
hood.
3. The descent rate needle valve is located on the base of the jack. Turn the needle valve clockwise with a
screwdriver to decrease the rate of descent. Turn it counterclockwise to increase the rate of descent.
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 wooden blocks 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.
