Summary of Safety Precautions
The following is a list of safety precautions that must be observed when operating or servicing this unit. The
precautions are repeated throughout the manual, where applicable. Carefully read this list before using or
servicing the unit.
WARNING
SImproper usage of the Cot can cause injury to the patient or operator and/or damage to
the cot. Operate the cot only as described in this manual.
SAlways use all restraint straps to secure the patient on the cot. An unrestrained or partially restrained
patient may fall from the cot and be injured.
SSiderails are not intended to serve as a patient restraint device. Refer to pages 17 & 18 for proper restraint
strap usage. Failure to use the siderails properly could result in patient injury or damage to the cot.
SNever leave a patient unattended on the cot or injury could result. Hold the cot securely while a patient
is on the cot.
SThe wheel lock is only intended to help prevent the cot from rolling while unattended. The wheel lock may
not provide sufficient resistance on all surfaces or under loads.
SNever apply the optional wheel lock while a patient is on the cot. Tipping could occur if the cot is moved
while the wheel lock is applied, resulting in injury to the patient or operator and/or damage to the cot.
SNever install or use the wheel lock on a cot with excessively worn wheels. Installing or using the wheel
lock on a wheel with less than a 6” diameter could compromise the holding ability of the wheel lock, resulting in injury to the patient or operator and/or damage to the cot or other equipment.
SHigh obstacles such as curbing, steps or rough terrain can cause the cot to tip, possibly causing patient
or operator injury. If possible, obtain additional assistance (see page 31 for a reference chart) or take an
alternate route.
SHave the vehicle safety hook installed by a certified mechanic. Improper safety hook installation can
cause injury to the patient or operator and/or damage to the cot.
SFailure to install the safety hook can cause injury to the patient or operator. Install and use the safety
hook as described in this manual.
STo avoid injury, verify the safety bar has engaged the safety hook before removing the cot from the patient
compartment.
SThe Cot must have at least 5/8 inch of clearance between the ambulance bumper and
the cot to disengage the safety bar when unloading the cot from the ambulance. Verify the legs lock into
the load position and visually inspect the lock pin (see page 30) before disengaging the safety bar from
the safety hook. Failure to properly lock the cot into position can cause injury to the patient and/or operator
or damage to the cot.
SWhen the optional head end storage pouch is being used, ensure the pouch does not interfere with the
operation of the safety bar and or safety hook. Injury to the patient or operator and/or damage to the cot
could occur.
SLoading, unloading and changing the position of the cot requires a minimum of two trained operators work-
ing together. The operator(s) must be able to lift the total weight of the patient, cot and any other items
on the cot. (If additional assistance is needed, see the reference chart on page 31).
SWhen changing the height of the cot, always verify the base frame is securely locked into position before
releasing your grip on the litter frame. Visually inspect the locking pin on the patient leftside of the cot
to verify the lock pin is properly engaged (see page 30).
STo avoid injury, verify the has engaged the safety hook before removing the cot from the patient compart-
ment.

Summary of Safety Precautions
WARNING
SBe sure the undercarriage has engaged and locked before removing the loading wheels from the patient
compartment floor of the vehicle.
SAlways verify the base frame is securely locked into position before releasing your grip on the litter frame.
Visually inspect the locking pin on the patient left side of the cot to verify the lock pin is properly engaged
(see page 30). An unlocked base frame will not support the cot and injury to the patient or operator could
result.
SUnlock the auxiliary lock only to fold, change height position or load the cot. Improper use can cause injury
to the patient or operator.
SPractice folding, changing height position and loading the cot until operation of the auxiliary lock is fully
understood. Improper use can cause injury. Unlock the auxiliary lock only to fold, change height position
or load the cot.
SDo not allow untrained helpers to assist in the operation of the cot. Untrained technicians/helpers can
cause injury to the patient or themselves and/or damage to the cot.
SDo not step or ride on the base of the Cot. Damage to the cot could occur, resulting in
injury to the patient or operator.
SFailure to properly clean or dispose of contaminated mattress or cot components will increase the risk of
exposure to bloodborne pathogens and may cause injury to the patient or the operator.
STo avoid accidental release of the Pedi−Matet, and possible injury to the infant, ensure the buckle is lo-
cated away from obstructions on the cot or head end storage pouch.
SIf the cot has an optional foot end oxygen bottle holder, hold the leg rest on the sides to avoid pinching
your hand between the cot frame and the oxygen bottle when lowering the leg rest.
STo avoid equipment damage and/or injury to the patient, remove all items from the optional base storage
tray before loading or lowering the cot.
SWhen necessary, modify the vehicle to fit the cot. Do not modify the Cot. Modifying the
cot can cause unpredictable operation resulting in injury to the patient or operator or damage to the cot.
Modifying the cot will also void its warranty.
SDamage to the cot can occur if the cot is lowered in the shortened position. Use only positions 2 − 5 (see
page 15) when the cot is shortened.
SOperating the cot with the breakaway head section lowered may cause injury to the patient or operator
or damage to the cot. Use only positions 4−5(see page 14) when using this configuration.
CAUTION
SInstall the safety hook at least 1/8 inch from the edge of the rear ambulance door. After installation, verify
the cot legs lock into the load position without contacting the ambulance bumper.
STo properly engage the safety hook, a height limit kit is recommended for ambulance deck heights less
than 30 inches (76 cm) − Stryker part number 6092−202−010.
SDo not store items under the cot mattress. Storing items under the mattress can interfere with the opera-
tion of the cot.
SDo not steam clean, pressure wash, hose off or ultrasonically clean this unit. High pressure water
or steam can remove lubricants and cause corrosion. Clean the cot as described on page 37.
STo avoid damage, the weight of the I.V. bags should not exceed 40 pounds.
SImproper maintenance can cause injury to the patient or operator and/or damage to the unit. Maintain
the cot as described in this manual. Use only Stryker approved parts and maintenance procedures. Using
unapproved parts and procedures could cause unpredictable operation, damage to the cot and/or injury

Vehicle Safety Hook Installation
Ambulance Configuration
The vehicle safety hook is a device shipped with the cot. The safety bar and hook are designed to keep the
cot from being accidently removed from the ambulance and to provide increased operator assurance and
confidence when unloading. The vehicle safety hook was designed to ensure compatibility and proper operations of the cot during unloading when used in an ambulance vehicle compliant with Federal Regulation KKK−
A−1822.
According to federal regulations (reference KKK−A−1822), the bumper height of the ambulance shall be
installed equidistant 2 inches (5 cm) from the ambulance floor to the ground level, defined as the ambulance
deck height (Figure 3). The bumper step shall have a minimum depth of 5 inches (13 cm) and a maximum
depth of 10 inches (25 cm). If the bumper length is greater than 7 inches (18 cm), then the bumper must be
able to fold. Installation of the safety hook into any ambulance vehicle compliant with this federal specification
will provide adequate clearance for the cot base to lower to its fully extended position (Figure 4). The cot is
compatible with all ambulance deck heights up to 32 inches as long as the ambulance meets the federal specifications outlined in KKK−A−1822.
Height limit kit is recommended for ambulance deck heights less than 30 inches (76 cm) − Stryker part number
6092−202−010.
Installation of the safety hook should be done by a certified mechanic familiar with ambulance construction.
Consult the vehicle manufacturer before installing the safety hook and be sure the installation of the safety
hook does not damage or interfere with the brake lines, oxygen lines, fuel lines, fuel tank or electrical wiring
of the vehicle.
Required Hardware for Installation of the Safety Hook (Not Supplied)
(2) Grade 5, 1/4”−20 Socket Head Cap Screws *
(2) Grade 5, 1/4”−20 Flat Head Cap Screws *
(2) Flat Washers
(2) Lock Washers
(2) 1/4”−20 Nuts
* The length of the socket head cap screws depends on the thickness of the vehicle floor. Use screws long
enough to go completely through the patient compartment floor, washer and nut by at least two full threads.

Vehicle Safety Hook Installation
Positioning and Installing the Safety Hook
WARNING
Have the vehicle safety hook installed by a certified mechanic. Improper safety hook insatllatino can cause
injury to the patient and/or operator or damage to the cot.
Failure to install the safety hook can cause injury to the patient or operator. Install and use the safety hook
as described in this manual.
Install the safety hook at least 1/8 inch from the edge of the rear ambulance door. After installation, verify
the cot legs lock into the load position without contacting the ambulance bumper.
To avoid injury, verify the safety bar has engaged the safety hook before removing the cot from the patient
compartment.
Note: Stryker recommends that, prior to installation, the certified mechanic plan the placement of the safety
hook in the rear of the vehicle.
Procedure:
1.Remove the cot from the fastener and unload it
from the vehicle.
2.While the cot is being removed, note the position of
the loading wheels and the safety bar.
3.Center the safety hook on the cot safety bar, with
the hook facing the front of the vehicle (Figure 5a).
For best results, the face of the safety hook which
engages the safety bar should be at least 3−3/4”
from the leading edge of the door sill (Figure 5b)

4.Mark the position of the safety hook on the patient compartment floor. The safety hook should be installed
as close as possible to the rear of the vehicle while allowing the vehicle doors to close and checking that
the load wheels always remain on the patient compartment floor (i.e. wheels do not roll off the door sill
when the cot safety bar engages the safety hook) when the cot is loaded and unloaded from road and/or
curb height (Figure 6).
5.Ensure the bumper and bumper step do not interfere with the operation of the cot.
6.Drill the holes for the socket head cap screws.
7.Fasten the safety hook to the patient compartment floor and verify that the safety hook always engages
the cot safety bar when the cot is unloaded from the vehicle (Figure 7).

Cot User Tips
Disengaging the auxiliary lock
The auxiliary lock must always be disengaged to lower the cot from the load position or to load the cot into
the ambulance. It is located at the foot end of the cot on patient’s left side. Push the lock lever towards the
head end to disengage the auxiliary lock.
Auxiliary lock resets automatically
The auxiliary lock automatically resets after the red release handle is squeezed and released. If this occurs
while the cot is still in the load (or highest) position, you must disengage the auxiliary lock again before loading
or lowering the cot.
Auxiliary lock only locks in the load position
When the cot is in any position other than the load position (highest position), there is no need to disengage
the auxiliary lock.
Built in safety feature (lift then squeeze)
The cot has a built in safety feature which requires both operators to lift the cot slightly before the foot
end operator squeezes the red foot−end release handle. This feature ensures both operators are pre-
pared to lower the cot and decreases the chance of injury to the operators and/or patient. With an empty cot,
the operators may have to generate a downward force after squeezing the foot end release handle to start
the cot on its downward descent.
Squeeze foot−end release completely
After raising the cot slightly from both ends, squeeze thefoot end release handle all the way to the grip
to begin lowering the cot. Relaxing your grip on the handle once the cot starts downward allows the cot to
lock in any of the height positions. When raising the cot to a higher position, completely squeeze the foot
end release handle.
Transport at load−height position
You may transport the cot in the load height position. This eliminates the need for changing the height of the
cot prior to loading the cot into the vehicle. Note: Transport in the lowest height position appropriate to ensure
patient safety.
Cot is not flat in highest transport position
The cot litter is at a slight head−up/foot−down angle (reverse Trendelenburg) when it is in its highest transport
position to facilitate easy loading.
Unloading from Ambulance
It is not necessary to squeeze the foot end release handle when lowering the cot out of the ambulance.
One−step cot positioning
You can raise the cot from any position to the load position in one step.

Cot Operation
Using Restraint Straps
WARNING
Always use all restraint straps to secure the patient
on the cot. An unrestrained or partially restrained
patient may fall from the cot and be injured.
Always secure the patient on the cot with all the restraint straps. Buckle the restraints across the patient’s chest/shoulders, waist and legs (Figure 8).
WARNING
Never leave a patient unattended on the cot or injury
could result. Hold the cot securely while a patient
is on the cot.
When attaching the restraint straps to the cot, keep
in mind the attachment points should provide strong
anchorage and proper restraint position while not interfering with equipment and accessories. Wrap
the strap around the cot frame and back through the
loop on the end of the strap as shown in Figures 9
and 10. The arrows indicate alternate attachment
areas.
Figure 9 − Head Section Restraints
Keep the restraint straps buckled when the cot is not
being used with a patient to avoid damage to the
buckles and straps.

Figure 11 − Buckling the Restraints
When the cot is put into service, the restraints are opened and placed to either side of the cot until the patient
is positioned on the cot mattress. The restraint is lengthened, buckled around the patient and shortened until
the required tightness is achieved.
To open the restraint, press the red button (A) on the front of the buckle ”receiver”. This releases the buckle
”tang” (B) which can then be pulled out of the receiver (Figure 11).
To close the restraint, push the tang into the receiver until a ”click” is heard. When fastening the chest restraint
be sure the tang passes through both links (C) on the shoulder strap (Figure 11).
B
Figure 12 − Lengthening the Safety Restraints
Figure 13 − Tightening the Safety Restraint
To lengthen the restraint, grasp the buckle tang, turn it at an angle to the webbing, then pull out (Figure 12).
A hemmed tab at the end of the webbing prevents the tang from coming off the strap.
To shorten the restraint, grasp the hemmed tab and pull the webbing back through the tang until the required
tightness is achieved (Figure 13).
Whenever a restraint is buckled on a patient, the attendant should verify the tang is fully engaged and the
extra webbing is not tangled in the cot or hanging loose.
Inspection of the restraints should be done at least once a month (more frequently if used heavily). Inspection
should include checking for a bent or broken receiver or tang, torn or frayed webbing, etc. Any restraint showing wear or not operating properly must be replaced immediately.

the wheel lock is applied, resulting in injury to the patient or operator and/or damage to the cot.
ROLLING THE COT
1.Make sure all the restraint straps are securely
buckled around the patient (see pages 16 & 17 for
restraint strap usage instructions).
2.Place the cot in positions 2−5 for rolling (see page
14 for cot positions).
3.When rolling the cot, position an operator at the foot
end and one at the head end or the side at all times.
(If additional assistance is needed, see the reference chart on page 31).
4.During transport, approach door sills or other low
obstacles squarely and lift each set of wheels over
the obstacle separately.
Figure 20 − Rolling the Cot
WARNING
High obstacles such as curbing, steps or rough terrain can cause the cot to tip, possibly causing patient or
operator injury. If possible, obtain additional assistance (see page 31 for a reference chart) or take an alternate route.
Operating the Cot with the breakaway head section lowered may cause injury to the patient or operator or
damage to the cot. Use only positions 4−5 (see page 14) when using this configuration

CHANGING COT HEIGHT
WARNING
Loading, unloading and changing the position of the cot requires a minimum of two trained operators working
together. The operator(s) must be able to lift the total weight of the patient, cot and any other items on the
cot. (If additional assistance is needed, see the reference chart on page 30).
When changing the height of the cot, always verify the base frame is securely locked into position before releasing your grip on the litter frame. Visually inspect the locking pin on the patient left side of the cot to verify
the lock pin is engaged (see page 29).
Do not step or ride on the base of the Cot. Damage to the cot could occur, resulting in injury
to the patient or operator.
The EZ−PROr R4 has five height positions (see page 14):
SThe highest or loading position,
Sthree intermediate Transport positions,
Sa “Folded” position.
CHANGING BETWEEN LOADING AND FOLDED POSITIONS:
Changing From the Loading to the Folded Position:
1.To lower the cot from its loading position to its folded
position, two operators stand at opposite ends of the
cot and grasp the litter frame with palms facing up (as
shown in Figure 21).
2.The foot end operator unlocks the cot’s auxiliary lock,
located at the foot end on the patient’s left side. (The
auxiliary lock provides added security to help prevent
inadvertent drops.)
3.Both operators lift the cot until the weight is off the
latching mechanism (approximately 1/4”).
4.The foot end operator squeezes and holds the release handle and both operators lower the cot to the
folded position.

LOADING THE COT INTO A VEHICLE
When loading the cot into a vehicle, an operator should remember the following important information:
SThe higher the operator must lift the cot, the more difficult it becomes to hold the weight. The operator
may need help loading the cot into a vehicle if he/she is too short or if the patient is too heavy for the operator to lift safely. The operator should only lift the cot to a horizontal position when loading the cot. (If additional assistance is needed, see the reference chart on page 30).
SThe operator must be able to lift the cot high enough for the cot’s base frame to unfold completely and
lock when the cot is unloaded. A shorter operator will have to raise his/her arms higher to enable the base
frame to unfold. (If additional assistance is needed, see the reference chart on page 30).
WARNING
Loading, unloading and changing the position of the cot requires a minimum of two trained operators working
together. The operator(s) must be able to lift the total weight of the patient, cot and any other items on the
cot. (If additional assistance is needed, see the reference chart on page 30).

Thoroughly clean the cot once a month. 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.)
Washing Procedure:
Foollow the cleaning solution manufacturer’s dilution recommendations exactly.
In general, when used in those concentrations recommended by the manufacturer, either phenolic type or
quaternary type disinfectants can be used. Iodophor type disinfectants are not recommended for use because staining may result.
Chlorinated Bleach Solution (5.25% − less than 1 part bleach to 100 parts water)
Avoid over−saturation and ensure the product does not stay wet longer than the chemical manufacturer’s
guidelines for proper disinfecting.
WARNING
SOME CLEANING PRODUCTS ARE CORROSIVE IN NATURE AND MAY CAUSE DAMAGE TO THE
PRODUCT IF USED IMPROPERLY. If the products described above are used to clean Stryker patient care
equipment, measures must be taken to insure the cots are wiped with clean water and thoroughly dried following cleaning. Failure to properly rinse and dry the cots will leave a corrosive residue on the surface of the
cots, possibly causing premature corrosion of critical components.
NOTE
Failure to follow the above directions when using these types of cleaners may void this product’s warranty.
REMOVAL OF IODINE COMPOUNDS
Use a solution of 1/2 tablespoons Sodium Thiosulfate in a pint of warm water to clean the stained area.
Clean as soon as possible after staining occurs. If stains are not immediately removed, allow solution to
soak or stand on the surface. Rinse surfaces which have been exposed to the solution in clear water before
returning unit to service.
WARNING
Failure to properly clean or dispose of contaminated mattress or cot components will increase the risk of exposure to bloodborne pathogens and may cause injury to the patient or the operator.
