Safety Tips and Guidelines
Before operating the 2040 Patient Transport Frame, it is important to read and understand all information in this manual.
Carefully read and strictly follow the safety guidelines listed on this page. To ensure safe operation of the transport
frame, methods and procedures must be established for educating and training hospital staff on the intrinsic risks
associated with the usage of motorized electric units
WARNINGS
• The 2040 Patient Transport Frame 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.
• Serious injury can result if caution is not used when operating the unit. Operate the unit only when all persons are
clear of the electrical and mechanical systems.
• To help reduce the number and severity of falls by patients, always leave the bed in the lowest position 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 attending medical personnel to determine the degree of restraint and the siderail positioning
necessary to ensure a patient will remain safely in bed.
• Always apply the caster brakes when a patient is getting on or off the bed. Always keep the caster brakes applied
when a patient is on the bed (except during transport). Injury could result if the bed moves while a patient is getting
in or out of bed.
• Ensure the brakes are completely released prior to attempting to move the unit. Attempting to move the unit with
the brakes actuated could result in injury to the user and/or patient.
• Put the drive wheel in the neutral position and release the brakes before pushing the unit manually. Do not attempt
to push the unit manually with the drive wheel engaged. The unit will be difficult to push and injury could result.
• The CPR emergency release requires assistance to lower the Back if the angle of the Back is above 80°. Attempting
to lower the Back in this position without assistance may result in injury to the operator.
• The power save mode is activated after one hour on battery power with no motion release switch activation.
Functions, including Bed Exit scale and motion, will cease to operate when the unit enters the power save mode.
Injury to the patient could occur if proper patient monitoring protocol is not observed.
• The Bed Exit System is intended only to aid in the detection of a patient exiting the unit. It is not intended to replace
patient monitoring protocol. The bed exit system signals when a patient is about to exit. Adding or subtracting
objects from the frame after arming the bed exit system may cause a reduction in the sensitivity of the bed exit
system.
• To avoid pinching your fingers, place the I.V. pole in the upright position before using the drive handle.
• Always unplug the power cord and push the battery power on/off switch to the “Off” position before service or
cleaning. When working under the frame, always place blocks under the litter frame to prevent injuries in case the
Bed Down switch is accidently activated.
• 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.
• The 2040 Patient Transport Frame is intended for use by trained hospital personnel only.
Service only by qualified personnel. Refer to maintenance manual.
• Do not modify the 2040 Patient Transport Frame. Modifying the unit can cause unpredictable operation resulting
in injury to the patient or operator. Modifying the unit will also void its warranty.
• When using any mattress and/or mattress overlay that increases the overall height greater than 6” extra caution
and/or operator supervision is required to help reduce the likelihood of a patient fall occurring.
Summary of Safety Precautions
Return To Table of Contents

www.stryker.com 2040-309-002 REV B 11
Safety Tips and Guidelines (Continued)
To avoid possible injury and to assure proper operation when using a powered mattress replacement system such as
XPRT:
• Confirm proper scale system operation following mattress installation. For best results, secure the therapy mattress
power cord to prevent damage to the cord or interference with the bed frame and the scale system.
• Do not zero bed scales or weigh patient with Percussion, Vibration, Rotation or Turn-Assist active. Patient motion
and position resulting from the dynamic therapy mattress may adversely affect scale system performance.
• Do not initialize (“Arm”) bed exit with Percussion, Vibration, Rotation or Turn-Assist active. The patient motion and
position resulting from the dynamic therapy mattress may adversely affect bed exit system performance.
• When using an XPRT Therapy Mattress extra caution and/or operator supervision is required to help reduce the
likelihood of a patient fall occurring.
CAUTIONS
• Use caution while maneuvering the unit with the drive wheel activated. Always ensure there are no obstacles
near the unit while the drive wheel is activated. Injury to the patient, user, bystanders or damage to the frame or
surrounding equipment could occur if the unit collides with an obstacle.
• Use caution when transporting the unit down halls, through doors, in and out of elevators, etc. Damage to the
siderails or other parts of the unit could occur if the unit comes in contact with walls or door frames.
• If unanticipated motion occurs, unplug the power cord from the wall socket, push the battery power on/off switch
to the “Off” position (the LED will not be illuminated) and actuate the drive wheel pedal to the neutral position.
• The siderails are not intended to be used as a pushing device. Damage to the siderails could occur.
• The use of a mattress overlay may reduce the effectiveness of the siderail.
• When attaching equipment to the frame, ensure it will not impede normal operation. I.E.: Hooks on hanging
equipment must not actuate control buttons, equipment must not hide the nurse call button, etc.
• Use caution when lowering the bed with items attached to the optional accessory rail. If caution is not used, items
may contact the floor resulting in damage to the items and/or injury to the patient or user.
• The lockout buttons on the foot board lock the Fowler, Gatch and Bed Up/Down functions and prevent motion of
the bed. It is the responsibility of attending medical personnel to determine whether these functions should be
locked and to use the buttons accordingly.
• Scale function may be affected by siderail/caster interference. With the litter fully lowered or lowered in Reverse
Trendelenburg, the siderails tucked under the litter in the storage position and the casters turned, there is the
potential for interference between the siderail and the caster. Raise the siderails when lowering the litter to the full
down position to prevent the interference from causing the bed’s scale system to weigh inaccurately.
• If large fluid spills occur in the area of the circuit boards or motors, immediately unplug the power cord from the
wall socket and push the battery power on/off switch to the “Off” position. Remove the patient from the unit and
clean up the fluid. Have maintenance completely check the unit. Fluids can short out controls and may cause
the unit to operate erratically or make some functions completely inoperable. Component failure caused by fluids
could even cause the unit to operate unpredictably and could cause injury to the patient. Do not put the unit back
into service until it is completely dry and has been thoroughly tested for safe operation.
• Preventative maintenance should be performed at a minimum of annually to ensure all features are functioning as
designed. Close attention should be given to safety features including, but not limited to:
• Safety side latching mechanisms,
• Caster braking systems,
• Leakage current 300 microamps max.
• No controls or cabling entangLED in frame mechanisms.
• Frayed electrical cords and components.
• All controls return to off or neutral position when released
• The battery tray assembly weighs 50 pounds. Take care when removing the two hexagonal head screws securing
it to the base frame or personal injury could result.
• The 2040 Patient Transport Frame is not intended for pediatric use or for patients under 50 pounds.

Summary of Safety Precautions
Return To Table of Contents
Safety Tips and Guidelines (Continued)
• Because individual beds may have different options, foot boards should not be moved from one bed to another.
Interchanging foot boards between beds could result in unpredictable bed operation.
• The weight of the I.V. bags should not exceed 40 pounds.
• Do not add or remove weight when the bed exit system is armed.
• The cleanliness and integrity of both ground chains must be maintained to minimize static build up and
discharge.
• I.V. Poles should not be used as a bed push/pull device.
The following Caution statements apply to the optional 110V outlet:
• Maximum total load 5A receptacle rating: 125 VAC, 5A, 60 Hz.
• The total system chassis risk current should not exceed 300 uA.
• Grounding continuity should be checked periodically.
