INTRODUCTION
This manual is designed to assist you with the maintenance of the 1212 Emergency Care Stretcher. Read
it thoroughly before using the equipment or beginning any maintenance on it.

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.

Preventative Maintenance
CLEANING
1. Hand wash all surfaces of the bed 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.

HYDRAULIC SYSTEM TROUBLESHOOTING
NOTE
Be sure the pedal linkage has been adjusted properly before beginning service on the jacks (see page 8).
PROBLEM/SYMPTOM SOLUTION
Jack will not raise to full height. Check for leaks. Add hydraulic fluid (see p. 11).
Jack will not hold in raised position. Check linkage to ensure it is not engaged. If link-
age is engaged, use a 7/16”socket or wrench to
back off the nut until the jack drift stops.
If the jack still does not hold, replace valve #1 (see
p. 12).
Jack will not pump up and the jack actuator rod
does not move. Close the needle valve. If the jack still will not
pump up after closing the needle valve, replace
valve #2 (see p. 13).
Jack will not pump up but the jack actuator rod
does move when the pump pedal is activated. Replace valve #2 (see p. 13).
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
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.
(The factory settings are 3/4 turn from closed for the head end and 1 1/2 turn from closed for the foot 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.

HYDRAULIC CHECK VALVE REPLACEMENT
Required Tools:
3/8 Open End Wrench Stiff Wire (with bent, pointed end) Small Needle Nose Pliers
3/4 Open End Wrench Torque Wrench (with Ft. Lbs. adjust.) 7/32 Hex Allen Wrench
1/2 Inch Diameter Rod
Replacement of Valve #1
WARNING
To avoid personal injury or damage to the stretcher, remove the litter and the base hood before beginning
service on the jacks. Lower the jack rod completely to relieve the pressure on the pump piston side of the
jack. This will prevent large hydraulic fluid loss and possible damage when the base plugs are removed.
1. Remove the base plug (3) and discard the seal (4).
2. Remove the valve plug (5).
3. Using a stiff wire with a bent, pointed end, remove the valve (1) and the seal (6) and discard the seal.
4. Install the new seal (6) flat to the bottom of its hole with a 1/2”diameter rod.
5. Install the new valve (1) with the beveled end out (as shown in the illustration).
6. Install the valve plug (5) and tighten to 10 foot–pounds torque.
7. Install the new seal (4) with the base plug (3) and tighten to 10 foot–pounds torque.
8. Pump up the jack to the maximum height.
9. Be sure there are no hydraulic leaks before replacing the base hood and the litter.

HYDRAULIC CHECK VALVE REPLACEMENT (CONTINUED)
Replacement of Valve (Poppet) #2
WARNING
To avoid personal injury or damage to the stretcher, remove the litter and the base hood before beginning
service on the jacks. Lower the jack rod completely to relieve the pressure on the pump piston side of the
jack. This will prevent large hydraulic fluid loss and possible damage when the base plugs are removed.
1. Remove the base plug (7) and discard the seal (8).
2. Remove the compression spring (9).
3. Using a small needle nose pliers, remove the poppet (2).
4. Install the new poppet (2).
5. Install the compression spring (9).
6. Install the new seal (8) and the base plug (7) and tighten to 10 foot–pounds torque.
7. Pump up the jack to the maximum height to check its operation.
8. Check for hydraulic leaks before replacing the base hood and the litter.
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 8).
2. Using pump pedal, actuate system several times. This will force the air through the system and the jack
should now pump up.
