2. PREVENTATIVE MAINTENANCE
2.1 BED CLEANING AND MATTRESS CARE
Always unplug the bed power cord from the wall outlet when cleaning or servicing the bed.
Do not use harsh cleaners, solvents or detergents. Do not steam clean, hose off or
ultrasonically clean the bed. Do not immerse any part of the bed. The bed electrical parts may
be damaged by exposure to water.
Germicidal disinfectant, used as directed, and/or Chlorine Bleach products are not considered
mild detergents. These products are corrosive in nature and may cause damage to your bed if
used improperly. If these types of products are used, ensure the beds are wiped with clean
water and thoroughly dried following cleaning. Failure to properly rinse and dry the beds will
leave a corrosive residue on the surface of the bed, possibly causing premature corrosion of
critical components. Failure to follow the above directions when using these types of cleaners
may void this product warranty.
CLEANING BEDS
Hand wash all surfaces of the bed with a soft cloth moistened with a solution of lukewarm water
and a mild detergent.
Wipe the bed clean and dry thoroughly to avoid build up of cleaning solution.
MATTRESS CARE
Inspect the mattress after each use. Discontinue use if any cracks or rips, which may allow fluid
to enter the mattress, are found in the mattress cover. Failure to properly clean the mattress, or
dispose of it if defective, may increase the risk of exposure to pathogenic substances and may
bring about diseases to the patient and user.
•Inspection
Implement local policies to address regular care, maintenance, and cleaning of mattresses and
covers. The cover cleaning procedure can be found below and on the mattress label.
Inspect mattress cover surface (also zip fasteners and cover inner surface if mattresses have
zip fasteners) regularly for signs of damage. If the mattress cover is heavily stained or soiled, or
is torn, remove the mattress from service.
•Cleaning
Stains: Wash with lukewarm water using a mild detergent. Rinse with water and let dry. For
tough stains use bleach diluted with ten parts of water.

2.3 PREVENTATIVE MAINTENANCE PROGRAM
When servicing beds, use only identical replacement parts provided by Stryker.
ANNUAL CHECKLIST
⎯All fasteners secure.
⎯Inspect for excessive wear the oil-impregnated bronze shoulder spacers found at the bed
hinge points. Replace as needed. Do not lubricate these spacers.
⎯Check the grease present on the actuator screws, lubricate if needed (see section2.2). The
actuator screws need lubrication every two years.
⎯On both sides of the bed, depress fully down the side of the pedal identified with a red
sticker and ensure that the brakes are applied and the bed immobilized. Toggle the pedal to
neutral and ensure the brakes are released.
⎯On both sides of the bed, depress fully down the side of the pedal identified with a green
sticker and ensure that the steer wheel is engaged. Toggle the pedal to neutral and ensure
that the steer wheel disengages.
⎯Siderails move, latch and stow properly.
⎯All functions of the foot end control panel working properly, including LEDs.
⎯All siderail controls working properly.
⎯Ensure that the optional nurse call works properly and that the alarm sounds in the nurse
station.
⎯Verify the CPR emergency release (optional) using both CPR release handles: raise the
Fowler fully up and, using the CPR handle, lower the Fowler gradually to flat position by
pulling, holding and releasing the handle several times. Ensure the Knee Gatch (if raised)
also starts flattening when the Fowler is completely down. Following the complete lowering
of the Fowler, wait approximately 30 seconds - the time for the Fowler control motor to reset
itself - and verify that the motor has indeed reset itself by raising the Fowler fully up using
the Fowler up control.
⎯Verify the Fowler, Knee Gatch and Hi-lo movements to ensure that the limit switch
integrated to the four electric actuators is operating properly.
⎯Auxiliary outlet (option available only with 120V beds) working properly.
⎯Night light (optional) working properly.
⎯No cracks in the boards, siderails, caster covers and 5th wheel hood (optional).
⎯Head end bumpers tightly secured to frame and working properly.
⎯No rips or cracks in mattress cover.
⎯Power cord not frayed.
⎯No cables worn or pinched.
⎯All electrical connections tight.
⎯All grounds secure to the frame.
⎯All casters roll properly. Check caster for cuts, wear, etc.
⎯Measure current leakage and grounding continuity of the bed and the optional auxiliary
outlet. Check with our Technical Service department for the acceptable values.

3. TROUBLESHOOTING
Please consult the following troubleshooting guide before calling the Technical Service department
(see section 1.2).
3.1 TROUBLESHOOTING GUIDE
PROBLEM/FAILURE WHAT TO CHECK
No power to bed
•Is the bed power switch at the head end of
the bed turned on?
•Is the power cord connected to the power
connector and plugged into the wall outlet?
•Is the power cord severed? Replace if
needed.
•Are the two fuses inside the power
connector still operational (see page 34)
•Verify power at wall outlet.
No bed up or down motion when:
•the siderail command is used
•the foot end command is used
•Is the total lockout activated (LED (padlock)
on) ? If so, deactivate it.
•Is the cable of the siderail control panel
properly connected to the bed receptacle
under the mattress support?
•Check points of the “No power to bed”
problem described above.
No Fowler up or down motion when:
•the siderail command is used
•the foot end command is used
•Is the Fowler lockout activated (LED
(padlock) on) ? If so, deactivate it.
•Is the total lockout activated (LED (padlock)
on) ? If so, deactivate it.
•Is the cable of the siderail control panel
properly connected to the bed connector
under the mattress support?
•Check points of the “No power to bed”
problem described above.
The Fowler does not fully raise This situation happens when the CPR handle
is used to partly lower the Fowler. The use of
the CPR mechanism for this purpose creates a
situation where the Fowler motor is out of sync
with the actual position of the Fowler. To
correct the situation:
•Completely lower the Fowler using the
CPR handle or the Fowler down control to
enable the Fowler motor to reset itself.
Refer to the "CPR Emergency Release"
section of the Operations Manual for more
information.

Do not reuse the self-sticking parts removed since their self-adhesive coating considerably
looses its efficiency once they are removed. We recommend that you have replacement stickers
at hand (see Recommended Spare Parts on page 13).
4. Using a Phillips screwdriver, remove the eight screws (D) holding the cover to the siderail
and remove the cover.
The eight screws (D) used to hold the siderail cover cannot be used more than once because
their Scotch-Grip coating is less efficient once they have been tightened and removed
thereafter. They must be replaced with new identical screws.
5. Remove the yellow locking lever (E).
6. Using a 3/16" Allen key, remove the four Allen screws (F) holding each pommel to the
siderail arms. Leave one loosened screw on each pommel until ready to remove both
pommels.

Apply medium-strength thread locker on the screw threads before replacing the screws.
7. While supporting the rail, remove the two last screws, the pommels, the bungee cord (if
applicable) and finally the rail.

Note the position of the pommel with the lock when the siderail is fully raised. The rail will not
lock in high position if the pommel is positioned differently.
