Stryker Stretcher 5051

Refer to drawing 5050–33–1 (page 56 & 57) for part reference.

Apply the Stretcher Chair brakes. For easier access, move Fowler to 70 or higher.

Remove the push bar (see page 22 or 23).

Using a 3/32” hex Allen wrench and a 3/8” box end wrench, remove the fasteners (item A), nuts (item S) and spacers (item AF) holding the Fowler covers (items AN & AP) located on the under side of the fiberesin. Remove the left and right Fowler covers and set aside.

Using a 3/32” hex Allen wrench, remove set screws (item Z), located in center of yokes (item AM).

Using a 5/8” box end wrench and a 5/16” hex Allen wrench, remove the pivot bolts (item E), flat washers (item L) and hex nuts (item W) holding the gas cylinders (item AK) to the litter frame.

To adjust the Fowler, turn the gas spring 1 to 2 turns counterclockwise if the Fowler will not move and 1 to 2 turns clockwise if the Fowler will not hold its position.

Replace the pivot bolts (item E) and check the Fowler adjustment. Lower the Fowler approximately 10 to 20, release the handle and apply weight to the Fowler to assure it will hold its position. If the Fowler will not lower or will not hold its position when weight is applied, repeat step 7.

When the Fowler is properly adjusted, replace the washers and hex nuts to secure the pivot bolts.

Pump the litter up to full height

Remove both the large nuts (A) from the top of the pneumatic cylinder using two 17 mm. wrenches

Remove the nut (B) and bolt (C) from the bottom of the cylinder using a 5/16” hex Allen wrench and an 11/16” open end wrench

Raise the Fowler to 90 and remove the cylinder

Press down on the release pin on the replacement cylinder to fully extend the cylinder

Put the large nut on the new cylinder and screw it down securely

Install the nut (B) and bolt (C) on the bottom of the cylinder using a 5/16” hex Allen wrench and an 11/16” open end wrench

Pump the stretcher litter up to full height

Move the Fowler to 70 or higher

Loosen the two nuts (A) on the adjustment screw (B) using (2) 3/8” wrenches

Repeat for the other side of the Fowler

Raise the Fowler to the full up position

Pull down on both sides of the Fowler, squeeze both release handles and verify both pneumatic cylinders release equally

Loosen the two Phillips head screws on the handle linkage

Release the handle tension spring on the patient’s left side

Adjust the handles so there is a 3/4” gap between the outer Fowler frame and the handle

Tighten the two screws on the handle linkage bar and reattach the spring

It may be necessary to adjust the pneumatic cylinders (see page 25)
