Warranty
Stryker EMS, a division of the Stryker Corporation, offers two distinct warranty options
in the United States:
One (1) year parts and labor. Under this option, Stryker EMS warrants to the original
purchaser that its products should be free from manufacturing non−conformances that
affect product performance and customer satisfaction for a period of one (1) year after
date of delivery. Stryker’s obligation under this warranty is expressly limited to supply-
ing replacement parts and labor for, or replacing, at its option, any product that is, in
the sole discretion of Stryker, found to be defective.
Two (2) year parts. Under this option, Stryker EMS warrants to the original purchas-
er that non−expendable components of its products should be free from manufactur-
ing non−conformances that affect product performance and customer satisfaction for
a period of two (2) years after date of delivery. Stryker’s obligation under this warranty
is expressly limited to supplying replacement parts for, or replacing, at its option, any
product which is, in the sole discretion of Stryker, found to be defective. Expendable
components, i.e. mattresses, restraints, IV poles, storage nets, storage pouches, O2
straps, and other soft goods, have a one (1) year limited warranty with this option.
Under either warranty option, Stryker Medical EMS products are designed for a 7 year
expected service life under normal use, conditions, and with appropriate periodic
maintenance as described in the maintenance manual for each device. Stryker war-
rants to the original purchaser that the welds on its EMS products will be free from
structural defects for the expected 7 year life of the EMS product as long as the original
purchaser owns the product. Original purchasers will also obtain a three (3) year limit-
ed parts warranty for the X frame components of the MX−PRO R3 stretcher provided
they also purchase X−frame guards at the time of the original purchase and the guards
are installed on the MX−PRO before it is put into service.
If Stryker requests, products or parts for which an original purchaser makes a warranty
claim, the purchaser shall return the product or part prepaid freight to Stryker’s factory.
Any improper use or alteration or repair by unauthorized service providers in such a
manner as in Stryker’s judgment affects the product materially and adversely, shall
void this warranty. Any repair of Stryker products using parts not provided or autho-
rized by Stryker shall void this warranty. No employee or representative of Stryker is
authorized to change this warranty in any way.
This statement constitutes Stryker EMS’s entire warranty with respect to the aforesaid
equipment. STRYKER MAKES NO OTHER WARRANTY OR REPRESENTATION EI-
THER EXPRESSED OR IMPLIED, EXCEPT AS SET FORTH HERIN. THERE IS NO
WARRANTY OF MERCHANTABILITY AND THERE ARE NO WARRANTIES OF FIT-
NESS FOR ANY PARTICULAR PURPOSE. IN NO EVENT SHALL STRYKER BE LI-
ABLE HEREUNDER FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES ARIS-
ING FROM OR IN ANY MANNER RELATED TO SALES OR USE OF ANY SUCH
EQUIPMENT.

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
S Improper 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.
S 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.
S Siderails 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.
S Never leave a patient unattended on the cot or injury could result. Hold the cot securely while a patient
is on the cot.
S The 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.
S Never 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.
S Never 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.
S 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.
S Have 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.
S 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.
S To avoid injury, verify the safety bar has engaged the safety hook before removing the cot from the patient
compartment.
S The 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.

Summary of Safety Precautions
WARNING
S Be sure the undercarriage has engaged and locked before removing the loading wheels from the patient
compartment floor of the vehicle.
S 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 properly engaged
(see page 30). An unlocked base frame will not support the cot and injury to the patient or operator could
result.
S Unlock the auxiliary lock only to fold, change height position or load the cot. Improper use can cause injury
to the patient or operator.
S Practice 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.
S Do 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.
S 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.
S 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.
S To 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.
S If 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.
S To avoid equipment damage and/or injury to the patient, remove all items from the optional base storage
tray before loading or lowering the cot.
S When 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.
S Damage 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.
S 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.
CAUTION
S 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.
S To 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.
S Do not store items under the cot mattress. Storing items under the mattress can interfere with the opera-
tion of the cot.
S Do 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.
S To avoid damage, the weight of the I.V. bags should not exceed 40 pounds.
S Improper 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

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.

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 the foot 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.
For Pedi−Matet restraint instructions see page 18
and 19.

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.

2. Remove the sleeve (B). Rotate the sleeve counterclockwise to increase the pedal locking force and
clockwise to decrease the locking force. Insert the sleeve into the pedal. Reinstall the hex socket screw.
3. Test the pedal locking force before returning the cot to service.
LOADING THE COT INTO A VEHICLE
When loading the cot into a vehicle, an operator should remember the following important information:
S The 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).
S The 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).

Cot Operation
LOADING THE COT INTO A
VEHICLE (CONTINUED)
1. Place the cot in the loading position (see page 15).
2. Roll the cot to the open door of the patient
compartment, approaching the vehicle squarely.
3. Fold the vehicle bumper to the raised position (if
available).
4. Push the cot forward until both loading wheels are
on the patient compartment floor and the safety
bar passes the safety hook.
5. Operator 1 − Release the auxiliary lock.
WARNING
Unlock the auxiliary lock only to fold, change height
position or load the cot. Improper use can cause injury
to the patient or operator.
6. Operator 1 − Grasp and support the cot litter frame
at the foot end using an underhand grip.
7. Operator 1 − Lift the foot end of the cot until the
transport wheels are off the ground and the cot is
horizontal (Figure 32). Squeeze and hold the foot
end release handle and push the cot into the vehicle.
8. Operator 2 − As Operator 1 pushes the cot into the
vehicle, lift on the base frame to help the base
frame fold as the cot loads into the vehicle (Figure
33).
9. Both operators − Push the cot into the patient
compartment (Figure 34), engaging the cot fastener (not included).
10. Operator 1 − Let go of the foot end release handle.
NOTE
Loose items or debris on the patient compartment floor
can interfere with the smooth rolling of the cot and the
operation of the cot fastener. Keep the patient
compartment floor clear.

IMPORTANT NOTE
To recover from a loading attempt halted by the auxiliary lock, do the following:
1. Release the foot end release handle.
2. Be sure the auxiliary lock is in the locked position.
3. Return the cot to its transport wheels, and verify
the base frame is securely locked into position.
4. Retry the folding or loading procedure.

Cot Operation
UNLOADING THE COT FROM A VEHICLE
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).
Disengage the cot from the cot fastener.
Operator 1 − Grasp the foot end of the cot frame using an underhand grip. Pull the cot from the patient
compartment. As the cot is pulled out of the patient compartment, the base frame unfolds and the safety bar
catches the safety hook. The Operator must keep the foot end of the cot high enough for the base frame
to unfold completely and lock into place before the transport wheels make contact with the ground.
WARNING
To avoid injury, verify the safety bar has engaged the safety hook before removing the cot from the patient
compartment.
Operator 2 − As Operator 1 pulls the cot out of the patient compartment, grasp the base frame where indicated
by the lift here label and lower it to its fully extended position. Visually inspect the locking pin on the patient
left side of the cot to verify the pin is engaged as shown in Figure 35 on page 29.
WARNING
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 properly engaged (see
page 29). An unlocked base frame will not support the cot and injury to the patient or operator could result.
Operator 1 − When the base frame is unfolded and securely locked, lower the cot until the transport wheels
are on the ground. Pull the cot away from the ambulance until the loading wheels clear the patient compartment floor.
NOTE
The cot may be transported in the load height position although it may need to be lowered to an intermediate
position depending on conditions and operator preference.
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 30 for a reference chart) or take an alternate route.
