2. PREVENTATIVE MAINTENANCE
2.1 BED CLEANING AND MATTRESS CARE
Do not use harsh cleaners, solvents or detergents. Equipment damage could occur. 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 bed label.
Inspect the mattress cover inner and outer surfaces and the 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 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. Do not lubricate these spacers. Replace as needed.
⎯Check the grease present on the actuator screws, lubricate if needed (see section 2.2). 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 is 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 controls of the foot board panel working properly, including LED's.
⎯Calibrate the optional scale (see the scale calibration procedure on page 42).
⎯All siderail controls working properly.
⎯Ensure that the nurse call alarm sounds in the nurse station.
⎯Ensure that the Communication package controls operate properly.
⎯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 - and verify that the motor has indeed reset itself by raising the Fowler fully up.
⎯Verify the Fowler, Knee Gatch and Hi-lo movements to ensure that the motion interrupt
switch integrated to the four electric actuators is operating properly.
⎯Auxiliary outlet (option available only with 120V beds) working properly.
⎯Night light (option) working properly.
⎯No cracks in the boards, siderails, wheel covers, steer wheel hood (optional) and molded
shells of the head and foot sections. Velcro strips of items previously enumerated match
properly.
⎯Head end bumpers tightly secured to frame and working properly.
⎯No rips or cracks in mattress cover.
⎯Power cord not frayed.
⎯No cables pinched or worn.
⎯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 (see section 1.2) 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 power cord connected to the power
connector and plugged into the wall outlet?
•Is the bed power switch at the head end of
the bed turned on?
•Is the power cord severed? Replace if
needed.
•Are the two fuses inside the power
connector still operational (see page 37)?
•Verify power at wall outlet.
No bed up or down motion when:
•the siderail command is used
•the foot board 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 board 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 "Emergency CPR Release"
section of the Operations Manual for more
information.

switches.
Improper operation of the CPR positioning:
Knee Gatch does not lower and/or the Fowler
actuator does not reset.
•Check and replace if needed (see pages
45 and 46) the two CPR limit switches.
The weight shown on the scale display is
incorrect. •Zero the bed without the patient in it (see
the "Weigh System Usage" section in the
Operations Manual).
•Calibrate the scale (see page 42).
Scale display reads OVERLOAD or shows
incorrect weight. •The weight present on the bed is superior
to the scale capacity, which is 500 lb (227
kg). If the patient weight is superior to 500
lb (227 kg), do not use the scale.
If it is not the case, zero the scale after
having removed the patient from the bed.
This situation often results from equipment
added to the bed without using the
add/remove equipment procedure. The
weight of this equipment is then added to
the patient's weight.
•One or more load cell cable not properly
connected or completely disconnected from
the scale control board (see figure 4.3E,
page 38 for the connecting positions of the
load cell cable).
Angle shown on the scale display is incorrect
•Calibrate the scale (see page 42).

All lockout LEDs (padlock icons) flash or the
word Error appears at the bottom of the LCD
display.
•The scale is unable to measure the
weight due to an electrical problem.
Please contact our Technical Service
(see section 1.2).
Bed Exit system does not operate properly. •Verify that the load cell cables are properly
connected to the scale control board (see
figure 4.3E, page 38) for the illustration of
the load cell cable connecting positions).
Bed Exit system does not work at all or alarm
goes off when Bed Exit is activated.
•Check points of the “No power to bed”
problem described above.
•One or more load cell cable are not
properly connected or are completely
disconnected from the scale control board
(see figure 4.3E, page 38 for the load cell
cable connecting positions).
Nurse call or Bed Exit signal does not reach
the nurse desk. •Check points of the “No power to bed”
problem described above.
•Check the wall outlet.

4. MAINTENANCE PROCEDURES
Only field technicians from Stryker or service personnel trained by Stryker should perform the
procedures detailed in this maintenance manual, especially those related to the Scale (option)
and Bed Exit (option) systems. Failure to observe this restriction can result in serious damage to
material and/or severe injury to people.
To prevent injury when working under the bed with the bed in the high position, always place
blocks under the mattress support frame and apply the brakes.
Always unplug the bed power cord from the wall outlet when servicing or cleaning the bed.
NOTE
Throughout this maintenance manual, the words “right” and “left” refer to the right and left sides
of a patient lying face up on the bed.
