Cleaning
Hand wash all surfaces of the stretcher with warm water and mild detergent. Dry thoroughly. DO NOT
STEAM CLEAN, PRESSURE WASH, HOSE OFF OR ULTRASONICALLY CLEAN. Using these methods
of cleaning is not recommended and may void this product’s warranty.
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.)
In general, when used in those concentrations recommended by the manufacturer, either phenolic type or
quaternary type disinfectants can be used. Iodophor type disinfectants are not recommended for use because staining may result. The following products have been tested and have been found not to have a harmful effect WHEN USED IN ACCORDANCE WITH MANUFACTURERS RECOMMENDED DILUTION.*

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 damage 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.
NOTE
Failure to follow the above directions when using these types of cleaners may void this product’s warranty.
REMOVAL OF IODINE COMPOUNDS
This solution may be used to remove iodine stains from mattress cover and foam footrest pad surfaces.
1. Use a solution of 1–2 tablespoons Sodium Thiosulfate in a pint of warm water to clean the stained area.
Clean as soon as possible after staining occurs. If stains are not immediately removed, allow solution to
soak or stand on the surface.
2. Rinse surfaces which have been exposed to the solution in clear water before returning bed to service.

Small Standard Screwdriver (1/16” max. blade thickness x 1/4” width)
7/16” Diameter Rod, Dowel or Punch (Optional)
HEAD SECTION REMOVAL PROCEDURE
(Refer to drawing number 1068–232–10 pages 70 & 71 for part reference)
1. Raise the bed to a comfortable working height.
2. Remove the plastic neck piece cover (item X). Rotate the neck piece so it is parallel to the ground.
3. Using an 1/8” roll pin punch, punch out the 1/8” roll pin (item AX) in the back of the anti–rotation gear
(item K).
4. To loosen the anti–rotation adjustment wedge, use the screwdriver to hold the anti–rotation adjustment
screw (item M) from underneath the neck section and, using the 3/8” wrench or socket, loosen the lock
nut on top (item AK). (It is not necessary to completely remove the lock nut or adjustment screw).
5. Allow the head and neck assembly to drop down for easier access to the jam nuts (item AL) and flange
nuts (item AF) on the neck pivot rod (item T). Loosen the jam nut and the flange nut closest to the left
side (the gear and wedge side) on the pivot rod and spin the nuts as far to the left as possible.
WARNING
Support the head/neck assembly to prevent it from falling and causing damage or injury during the removal
of the neck pivot rod.
6. From the left side, push the neck pivot rod (item T) as far right as possible. A thin nylon washer (item AT)
may fall out from between the neck assembly and the Fowler adapter bracket on the left.
7. Spin the the jam nut and flange nut that were loosened in step 5 to the left and remove them from the rod.
Remove the second jam nut and flange nut. Being sure to support the head/neck assembly , push the
pivot rod out to the right. Another thin nylon washer may fall out from between the neck assembly and
the Fowler adapter bracket on the right.
HEAD SECTION INSTALLATION PROCEDURE
(Refer to drawing number 1068–232–10 pages 70 & 71 for part reference)
1. Put some grease on one of the thin nylon washers (item AT) and stick it to the left side of the Fowler adapter
bracket.
2. Slip the new head/neck assembly around both ends of the Fowler adapter bracket, keeping the nylon
washer in place between the assembly and the Fowler adapter bracket.
3. Align the holes on the left side of the head/neck assembly, the adapter bracket and the nylon washer. If
you have the optional 7/16” diameter rod, insert it through the holes to keep the parts in place.
CAUTION
It is important to put only one of the thin nylon washers on the left side. More than one can adversely affect
adjustability and functionality of the head/neck assembly.
4. On the right side of the assembly, insert nylon washers (items AS and AT) as needed to fill the gap between
the head/neck assembly and the Fowler adapter bracket.
5. Align the holes in the right side of the head/neck assembly with the Fowler adapter bracket and the nylon
washers. Insert the pivot rod (item T) from the right side with the small diameter end of the rod going in
first. With the pivot rod part way through, slip a jam nut (item AL) and a flange nut (item AF) with the flange
facing to the left and spin them on as far to the right side of the rod as possible.
6. Push the pivot rod just past the left side of the transfer link (item R) and insert the other flange nut (with
the flange facing to the right) and the other jam nut. Be sure both of these nuts are on the left side of the
transfer link and the two nuts put on in step 5 are on the right. Push the pivot rod through the support tab.
7. Put grease on the angled surface of the back of the anti–rotation gear (item K). Put the gear in place with
the angle side of the anti–rotation gear facing the adjustment wedge (item N) and the anti–rotation gear
teeth engaging the teeth of the gear on the Fowler adapter bracket.
8. Push the pivot rod through as far as it will go. Adjust the jam and flange nuts as necessary to allow the
pivot rod to move through the left side of the assembly. (If you used the optional 7/16” rod, the pivot rod
will push it out at this time. The 7/16” rod does allow the pivot rod to go through with minimal effort).
9. Rotate the head/neck assembly to a level position if you haven’t already done so.
10. Place a punch or other object through the hole on the right side of the pivot rod to provide something to
grasp when moving and aligning the rod. Align the hole on the back of the anti–rotation gear with the hole
in the left side of the pivot rod. The alignment can be checked by inserting a 1/8” roll pin punch through
the holes. Hammer the roll pin (item AX) into the holes through the gear and rod until it is flush with the
surface of the gear.
11. Spin the flange nut on the left side until it is touching the transfer link (item R). Pull the left release handle
and spin the flange nut closer to the transfer link. Let go of the release handle and see if the anti–rotation
gear is in full contact with the other gear. Continue this procedure until the handle snaps into the locked
position when released. There should be some resistance on the handle just before it reaches the locked
position to ensure full engagement of the gear teeth, but not so much that the handle doesn’t reach the
locked position.
12. Pull the left release handle again and adjust the flange nut on the right side inward until it touches the
right side of the transfer link. Release the handle. While holding the flange nut with a thin 3/4” wrench,
use the other 3/4” wrench to bring the jam nut up tight to the flange nut.
HEAD SECTION INSTALLATION PROCEDURE (CONTINUED)
(Refer to drawing number 1068–232–10 pages 70 & 71 for part reference)
13. Pull the left release handle again and be sure the anti–rotation gear pulls back as far as the adjustment
wedge will allow it to go. If it doesn’t go all the way, adjust the right side flange nut and jam nut to the
left until the anti–rotation gear reaches its full travel. While holding the flange nut with a thin 3/4” wrench,
use the other 3/4” wrench to bring the jam nut up tight to the flange nut. Repeat steps 11–13 until proper
adjustment of the release handle is achieved. When the adjustments are finished, be sure all the flange
and jam nuts are firmly locked together.
14. From under the head section, turn the anti–rotation adjustment screw (item M) counterclockwise until it
stops. Do not force it tighter! (You can adjust the neck section up high enough to see both sides of the
head section if it is easier).
15. While lifting lightly up and down on the head piece, push the adjustment wedge down as far as you can.
While holding the wedge down, turn the adjustment screw clockwise until you feel it contact the bottom
of the wedge. Holding the adjustment screw in this spot, tighten down the nut (item AK) on top of the
adjustment wedge.
16. Check the wedge adjustment by pulling and releasing the left handle and verifying the anti–rotation gear
has returned to its locked position against the other gear. If it hasn’t, the wedge is too tight. Adjust the
wedge by holding the adjustment screw and loosening the nut on top of the wedge. Turn the adjustment
screw clockwise in small amounts and tighten the nut again. Repeat the adjustment until the anti–rotation
gear is locking properly against the other gear.
17. If the neck section seems loose when it is lifted up and down, the adjustment wedge is too loose. The
adjustment procedure is the same as above except the adjustment screw is turned counterclockwise to
adjust the wedge tighter.
18. When all adjustments are complete, reinstall the plastic neck piece cover (item X).

Service Information
SIDERAIL LATCH ADJUSTMENT
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 readjustment. If adjustment must be done it is important to follow the procedure below. If it is no t don e pro per ly, 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 screw clockwise will DECREASEthe amount of play in the latching mechanism. Turning
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.
