Safety Tips and Guidelines
Before operating the 2030, it is important to read and understand all information in this manual. Carefully read
and strictly follow the safety guidelines listed on this page.
It is important that all users have been trained and educated on the inherent hazards associated with the
usage of electric beds.
WARNING
The 2030 is not intended for use with patients less than two years of age.
Powered bed mechanisms can cause serious injury. Operate bed only when all persons are clear of the
mechanisms.
To help reduce the number and severity of falls by patients, always leave the bed in the lowest position
when the patient is unattended.
Leave the siderails fully up and locked when the patient is unattended. When raising the siderails, listen
for the ”click” that indicates the siderail has locked in the up position. Pull firmly on the siderail to ensure
it is locked into position.
Siderails are not intended to be a patient restraint device. It is the responsibility of the attending medical
personnel to determine the degree of restraint necessary to ensure a patient will remain safely in bed.
Always keep the caster brakes applied when a patient is on the bed (except during transport). Serious
injury could result if the bed moves while a patient is getting in or out of bed. After the brake pedal is
applied, push on the bed to ensure the brakes are locked. When moving the bed, toggle the steer pedal
to put the bed in the steer mode. This locks the swivel motion of the right foot end caster and makes the
bed easier to move.
When large spills occur in the area of the circuit boards, 110 volt cables and motors, immediately unplug
the bed power cord from the wall socket. Remove the patient from the bed and clean up the fluid. Have
maintenance completely check the bed. Fluids can affect the operational capabilities of any electrical
product. DO NOT put the bed back into service until it is completely dry and has been thoroughly tested
for safe operation.
Do not steam clean or hose off the bed. Do not immerse any part of the bed. The internal electric parts
may be damaged by exposure to water. Hand wash all surfaces of the bed with warm water and mild
detergent. Dry thoroughly. Quaternary Germicidal Disinfectants, used as directed, and/or Chlorine
Bleach products, typically 5.25% Sodium 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 PROD-
UCTS ARE CORROSIVE IN NA TURE AND MAY CAUSE DAMAGE TO YOUR BED IF USED IMPROPERLY. If these types of products are used to clean Stryker patient care equipment, measures must be
taken to insure 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’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.)
Preventative maintenance should be performed at a minimum of biannually to ensure all bed features
are functioning properly. Close attention should be given to safety features including, but not limited to:
safety side latching mechanisms, frayed electrical cords and components, all electrical controls return
to off or neutral position when released, caster braking systems, no controls or cabling entangled in bed
mechanisms, leakage current 100 MA maximum, scale and bed exit systems calibrated properly.
Always unplug bed during service or cleaning. When working under the bed with the bed in the high posi-
tion, always place blocks under the litter frame and set the brakes to prevent injury in case the Bed Down
switch is accidently pressed.
Explosion Hazard – do not use bed in the presence of flammable anesthetics.
page 1–4
Safety Tips and Guidelines
WARNING
If your bed is equipped with the Epic II+ Option:
Always unplug the power cord and push the battery power on/off switch to the “OFF” position before ser-
vice or cleaning. When working under the transport frame, always place blocks under the litter frame to
prevent injury in case the Litter Down switch is accidently activated.
The battery tray assembly weighs 50 pounds. T ake care when removing the two hex head screws secur-
ing it to the base frame or personal injury could result.
Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known
to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after
handling.
WARNING
Potential pinch points
page 1–5
Set–Up Procedures
It is important that the 2030 is working properly before it is put into service. The following list will help ensure
that each part of the bed is tested.
Plug the bed into a properly grounded, hospital grade wall receptacle and ensure the ”Power” LED light
at the foot end of the bed comes on.
WARNING
The 2030 is equipped with a hospital grade plug for protection against shock hazard. It must be plugged directly into a properly grounded three–prong receptacle. Grounding reliability can be achieved only when a
hospital grade receptacle is used.
Plug the optional interface cable into the 37 pin connector under the litter frame at the head end of the
bed, and into the ”Patient Station”, ”Head Wall”, ”Docker Station”, or equivalent (whichever applies). Test
the interface cable to verify it is functioning properly.
WARNING
Use only a Stryker supplied interface cable. Use of any other cable may cause the bed to function improperly
which may result in patient or user injury.
Ensure the siderails raise, lower and store smoothly and lock in the up and intermediate positions
Ensure that all four casters lock when the brake pedal is engaged
NOTE
Ensure that the ”Brake Not Set” LEDs located on the outside of the head end siderails and on the foot board
control panel come on when the brakes are disengaged.
Run through each function on the foot board control panel to ensure that each function is working properly.
Run through each function on both head end siderails to ensure that each is working properly.
If your bed is equipped with the Epic+ Option:
Unplug the power cord from the wall socket. Push the battery power switch located on the lower left cor-
ner of the head end to the “ON” position. Again, verify each function on the foot board and siderails is
operating properly.
If any problems are found during bed set–up, contact Stryker Customer Service at 800–327–0770.
Damaged Merchandise
ICC Regulations require that claims for damaged merchandise must be made with the carrier within fifteen
(15) days of receipt of merchandise. DO NOT ACCEPT DAMAGED SHIPMENTS UNLESS SUCH DAMAGE
IS NOTED ON THE DELIVERY RECEIPT AT THE TIME OF RECEIPT. Stryker Customer Service must be
notified immediately. Stryker will aid the customer in filing a freight claim with the appropriate carrier for damages incurred. Claim will be limited in amount to the actual replacement cost. In the event that this information
is not received by Stryker within the fifteen (15) day period following the delivery of the merchandise, or the
damage was not noted on the delivery receipt at the time of receipt, the customer will be responsible for payment of the original invoice in full.
Claims for any short shipment must be made within thirty (30) days of invoice.

Optional Inverter Protection Features and Voltage Points
The optional Epic+ inverter has several features to prevent internal damage:
1. Low Battery Voltage – If the battery voltage at the inverter drops below the low voltage cut–off, an alarm
will sound and the inverter will shut of f. When battery voltage increases to 95% of nominal battery voltage,
the inverter will restart.
2. High Battery Voltage – If the battery voltage input rises above the high voltage cut–off, the inverter will
shut off. When the battery voltage input drops back within the normal voltage range, the inverter will restart.
3. Over–Temperature – If the inverter gets too hot, it will shut off. The overheating may be caused by high
ambient temp er a t u r e , b l o c k e d a i r f l o w o r a n ov e r load condition. When the inverter reaches an acceptable
temperature, it will restart.
4. Over–Power – The inverter will source up to its maximum power rating. If the load requires more, the
output voltage will be lowered to supply no more than its maximum power so the maximum power from
the inverter is reduced to a safe amount.
WARNING
The optional inverter generates 115VAC, the same as a wall receptacle. To prevent injury, do not put anything
into the electrical outlets other than an appliance power cord. Keep the outlets covered when not in use.
Do not submerge the unit or subject it to moisture.

GENERAL INFORMATION
This section contains tool lists and step–by–step procedures to assist with the maintenance and servicing
of the litter portion of your equipment.
In the text, the words “right” and “left” refer to the right and left sides of a patient lying face up on the bed.
1. Calibrate Scale: This is required in the field if a CPU board or a load cell is replaced.
2. Display Corner: This function displays the individual reference numbers for each load cell assembly and
can be used to isolate a defective load cell.
3. Init. to Defaults: This may be required in the field when replacing a CPU board or a load cell.
4. Erase E–prom: This is a factory setting not used in the field.
5. Display Factor: This is a factory setting not used in the field.
5. Exit Diagnostics: Changes made in the diagnostic mode must be saved in permanent memory using this
function. Switching off power without saving will reset all variables to their previous values.
Diagnostic Mode:
NOTE
It requires two people to enable the diagnostic mode for the scale system.
1. To enter diagnostic mode, unplug the bed’s power cord from the wall socket.
2. Press and hold down the LBS/KGS button.
3. While still holding the LBS/KGS button, plug the bed’s power cord into the wall socket.
4. After two seconds, release the LBS/KGS button. The LCD should display “CALIBRATE SCALE”. The
diagnostic mode is now active.
Displaying Individual Load Cell Outputs:
A defective load cell can be detected by entering diagnostics and displaying individual load cell outputs.
1. Enter the diagnostic mode. The LCD will display “CALIBRATE SCALE” when the diagnostic mode is acti-
vated.
2. Repeatedly press and release the up or down arrow button (ZERO or SCALE ON/OFF) until the LCD dis-
plays “DISPLAY CORNER”.
3. Press and release the ENTER button (LBS/KGS). The LCD should display “PICK CORNER NOW”.
The four buttons listed in the group below function as POSITION buttons corresponding with the four corners of the bed’s litter. Whenever the LCD displays “PICK CORNER NOW”, press one of these buttons
to select the load cell assembly at the desired corner.
A. ZERO = head end, patient’s left side
B. CHANGE EQUIP. = head end, patient’s right side
C. TREND/FOWLER ANGLE = foot end, patient’s right side
D. LBS/KGS = foot end, patient’s left side
4. Press and release the position button that corresponds with the load cell to be checked. The LCD should
display “X/X=NNN.N”. ”X/X” represents the initials of the selected corner, i.e. H/R will be displayed for
the patient’s head end, right side. ”NNN.N” represents the resistance of the load cell.
5. Repeat step four for each corner. Head end weight readings will normally be lower than foot end weights.
Weight readings should be constant. A drifting 000.0 or 999.9 weight, or a reading that does not change
when weight is applied to that corner of the bed indicates a problem with the selected load cell assembly
or load cell cable.
6. When all the load cell outputs have been checked, repeatedly press and release the SCALE ON/OFF but-
ton until the LCD displays “EXIT DIAGNOSTICS”. Press the ENTER button (LBS/KGS) to exit diagnostics.

Scale System Diagnostics and Calibration
Verifying Scale Accuracy:
1. Zero the empty bed. Place a known weight on the center of the bed; the heavier the better and no less
than 100 pounds. The displayed weight should be within 1% of the actual weight.
2. If the displayed weight is not accurate, remove the weight from the bed and proceed to the Scale Calibration
section.
Scale Calibration:
NOTE
It requires two people to enable the calibration mode for the scale system.
Raise the siderails when calibrating the scale to avoid getting inaccurate scale readings due to possible interference between the siderails and the casters.
Calibrate the scale system with a known 200 pound weight. If exactly 200 pounds is not available, the factory
default for calibration will have to be changed as described in step 8.
1. To enter the calibration mode, unplug the bed’s power cord from the wall socket.
2. Press and hold down the LBS/KGS button.
3. While still holding the LBS/KGS button, plug the bed’s power cord into the wall socket.
4. After two seconds, release the LBS/KGS button. The LCD should read “CALIBRATE SCALE”. The cal-
ibration mode is now active.
5. Using the up or down arrow button (ZERO or SCALE ON/OFF), toggle through the menu until “INIT . TO
DEFAULTS” is displayed. Press and hold the ENTER button (LBS/KGS) until “SAVING DEFAULTS” is
displayed. Release the ENTER button.
6. Using the up or down arrow buttons (ZERO or SCALE ON/OFF), toggle through the menu until “CALI-
BRATE SCALE” is displayed.
7. Press and hold the ENTER button (LBS/KGS). Zero the bed, following the displayed instructions. When
the bed is zeroed, the LCD should display “REF X100=<2 0000”. This is the factory default for 200
pounds. If 200 pounds will be used to calibrate the scale, proceed to step 9.
8. If exactly 200 pounds is not available, change the display to match the weight you are using. Pressing
the TREND/FOWLER ANGLE button will move the cursor position to the right. Pressing the up arrow
(ZERO) button will increase the numbers. Pressing the down arrow (SCALE ON/OFF) button will decrease the numbers. Scroll through the numbers until they match the weight you will use for calibration.
9. Press and release the SCALE ON/OFF button and the LCD will display “PRESS REV. TREND”. Press
the button with the Reverse Trendelenburg symbol (feet down/head up) until the bed reaches full reverse
Trend. Release the button and the LCD will display “DO NOT TOUCH BED”.
10. The LCD will display “PRESS TREND.” Press the button with the T rendelenburg symbol (feet up/head
down) until the bed reaches full trend. Release the button and the LCD will display “DO NOT T OUCH BED”.
11. The LCD will display “CALIBRATE SCALE”. This indicates the calibration procedure is complete.
12. Exit scale calibration by pressing the up arrow button (ZERO) until the LCD displays “EXIT DIAGNOSTICS”. Press the ENTER (LBS/KGS) button to exit.
13. Level the bed at a full up or full down position. Remove the weight and zero the bed.
14. Verify scale accuracy and functionality before returning the bed to service.

Load Cell Replacement
Required Tools:
9/16” Socket Wrench9/16” Open End WrenchSaw Horse (or Equivalent)
Wire Cutters
Replacement Procedure:
1. Raise the Fowler or knee section, depending which end of the litter needs service.
2. Unplug the load cell connector from the load cell cable.
3. Using wire cutters, remove the wire ties holding the cable to the frame.
4. Using a 9/16” socket and a 9/16” open end wrench, remove the two bolts holding the load cell to the litter
cross tube and remove the load cell.
5. Using a saw horse, support the litter at the end where the load cell was removed. Reverse the above
procedure to install the new load cell.
NOTE
Scale calibration procedure must be performed after the load cell is replaced (see page 7–3).
1. Run the litter to the full up position and remove the mattress from the bed.
2. Fold the foot section back toward the head end of the bed. Electrically run the knee section to full up.
If the knee section will not move electrically, pull the foot section toward the head end of the bed while
pulling the CPR release handle (located at the head end of the bed). The knee section will raise.
3. Using a T27 torx, remove the four screws holding the cover to the actuator box and remove the cover.
4. Remove the two CPR release cables from the CPR release bracket. Using a 3/8” socket wrench under-
neath the actuator box, remove the two bolts holding the release bracket to the actuator box and remove
the bracket from the actuator box.
5. Disconnect all the electrical connections going to the head motor and move aside any wiring that could
interfere with the removal of the motor.
6. Using a 3/8” socket wrench underneath the actuator box, remove the four bolts holding the motor mount-
ing bracket to the actuator box. Lift up and out on the motor to remove it.
7. Remove the motor mounting bracket from the old motor and install it on the replacement motor.
8. Reverse steps 3 through 6 to install the replacement motor.
9. Verify the bed is working properly before returning it to service.
1. Run the litter to the full up position and remove the mattress from the bed.
2. Fold the foot section back toward the head end of the bed. Electrically run the knee section to full up.
If the knee section will not move electrically, pull the foot section toward the head end of the bed while
pulling the CPR release handle (located at the head end of the bed). The knee section will raise.
3. Using a 7/16’ socket wrench, remove the mounting bolt on the litter for the knee dampening cylinder. This
leaves the knee dampener mounted only to the seat panel.
4. Using a T27 torx, remove the four screws holding the cover to the actuator box and remove the cover.
5. Remove the two CPR release cables from the CPR release bracket. Using a 3/8” socket wrench under-
neath the actuator box, remove the two bolts holding the release bracket to the actuator box and remove
the bracket from the actuator box.
6. Disconnect all the electrical connections going to the knee motor and move aside any wiring that could
interfere with the removal of the motor.
7. Pull the foot panel toward the head end of the bed. This causes the knee motor linkage to roll past center
and allows the motor to be removed without supporting the knee section.
