HYDRAULIC FLUID LEVEL CHECK (HYDRAULIC BASE)
TOOLS REQUIRED:
•
(2) Bungee Cords (or equivalent)
•
3/4 in. Socket
•
3/8 in. Drive Ratchet
•
Mobil Aero HFA Hydraulic Fluid (Stryker p/n: 2020-070-475)
PROCEDURE:
1. Raise the rails to the highest position and lower the litter to the lowest height. Apply the brakes.
2. Ensure there are no hydraulic fluid leaks. If leaks are present, replace the jack
(see page 1-35)
.
3. Remove the bottom part of the bellows from the base hood and support them using bungee cords (or equivalent)
to gain access to the fill plug.
4. Using a 3/4 in. socket, slowly turn the fill plug (located on the side of the reservoir) counter-clockwise to allow
excess system pressure to vent. Remove the fill plug.
5. The hydraulic fluid should be visible at the bottom of the hole. If the fluid cannot be seen, add Mobil Aero HFA
hydraulic fluid (p/n 2020-070-475) until the fluid level reaches the bottom of the hole. Replace the fill plug.
CAUTION
Using hydraulic fluids other than the recommended Mobil Aero HFA may cause damage to the jacks.
6. Verify proper jack operation before reinstalling the bellows and returning the stretcher to service.
