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.
CONSTANT FLOW 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 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 lower the foot end 3−7 seconds faster than the head. It
is recommended to have the foot end lower faster to avoid patient disorientation.
