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.

Service Information
PNEUMATIC FOWLER ADJUSTMENT
Required Tools:
3/32 Hex Allen Wrench Towel or Cloth
Channel Lock Pliers Thread ”Locktite”
Adjustment Procedure:
1. Refer to drawings 1026–127–31 (Full Length X–Ray Pneumatic Fowler Litter Assembly, page 40) and
926–175–55 (Pneumatic Fowler Assembly, page 42) for parts identification.
2. For easier access, move Fowler to 75 degrees or higher.
3. Using a 3/32 hex Allen wrench, remove set screws ”AL”(see drawing 1026–127–31) located in inside cen-
ter of item ”P”(see drawing 926–175–55).
4. Wrap a towel or cloth around the gas cylinder actuator shaft(s) so as not to mark the shaft. Using channel
lock pliers, turn the actuator shaft ”into”item ”P”for more positive contact with the control handle, or ”away”
from item ”P”for less contact with the control handle.
NOTE
More contact is necessary when activation of the cylinders is difficult. Less contact is necessary when the
Fowler does not support the weight of the patient.
5. Replace the set screws ”AL”using ”Loctite”and tighten completely.
6. Be sure that the Fowler activates and holds properly before returning the stretcher to service.
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 5 or 6).
2. Using pump pedal, actuate system several times. This will force the air through the system and the jack
should now pump up.

5
Service Information
PEDAL LINKAGE ADJUSTMENT – DUAL SIDE CONTROL BASE
Required Tools:
3/32 Hex Allen Wrench
7/16 Open End Wrench
1/2 Open End Wrench
(2) Wooden blocks (10 –12 inches in length)
Adjustment Procedure:
1. Pump the litter up to full height.
2. Lift the base hood, separating the hood from the base frame. Using the wooden blocks, support the base
hood.
3. To adjust the foot end descent pedal, use a 5/32 hex Allen wrench to loosen the set screw (C) in the stop
collar (D) on the release rod. Hold the pedal parallel to the floor and slide the collar up to the bracket on
the release rod. Tighten the set screw on the stop collar. Be sure the head end and foot end descent
pedals are level with each other. Repeat for the head end pedal, if necessary.
4. Once the pedals are level, be sure the paddle on the end of the release rod for the foot end jack is slightly
touching the actuating stem on the jack base. If it is not, use a 3/32 hex Allen wrench to loosen the set
screw on the paddle hub. Adjust the paddle to JUST touch the stem of the jack. Tighten the set screw
in the paddle hub. Repeat for the head end jack, if necessary.
5. Depress the pedal for the foot end jack. The jack should start to descend about the same time the paddle
on the end of the rod contacts the sleeve on the jack actuating stem. The bracket on the foot pedal body
should hit the stop screw (B). Any further movement could cause damage to the stem components inside
the jack housing. To adjust the stop screw, use a 1/2 open end wrench to loosen the hex jam nut (A).
Turn the screw and re–tighten the hex jam nut. Repeat for the head end jack.
6. Pump the litter up to full height.
7. Step on both descent pedals at the same time. Both ends of the litter should lower with the foot end lower-
ing slightly faster than the head end. If it does not, refer to the procedure for adjusting the jack descent
rate.
8. Remove the wooden blocks supporting the base hood. Use the pedal cut–outs on the side of the hood
as a guide for proper re–positioning.

Adjustment Procedure:
1. Pump the litter up to full height.
2. Lift the base hood, separating the hood from the base frame. Using the wooden blocks, support the base
hood.
3. The descent pedals should be level with each other and there should be approximately 4 inches between
the floor and the bottom of the pedal. To raise the pedal height, use a 1/2 open end wrench to loosen the
hex jam nut (E). Using your hand, turn the screw (D) into the bracket. To lower the pedal height, loosen
the screw. Tighten the hex jam nut (E) after the correct height is achieved.
4. Once the pedals are level, the release rod can be adjusted. Using a 7/16 wrench, turn nut (B) clockwise
to shorten the release length and counterclockwise to increase the length.
5. Depress the pedal and be sure the jack descent is triggered when the pedal is approximately one inch from
the floor. The descent should stop when the pedal is released and the jack height should hold. Repeat
the above procedures for the descent pedal at the other end of the bed.
6. After adjusting each descent pedal individually, depress both pedals at the same time. Both jacks should
start descending when the pedals are approximately one inch from the floor. The foot end should lower
slightly faster than the head end. If it does not, see procedure for adjusting the jack descent rate.
7. Remove the wooden blocks supporting the base hood and secure the hood to the base frame.
