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 supplying 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 purchaser that non­expendable components of its products should be free from manufacturing 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, I.V. poles, storage nets, storage
pouches, Oxygen straps, and other soft goods, have a one (1) year limited warranty with this option.

Under either warranty option, Stryker 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 warrants 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 limited 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 authorized 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 EITHER EXPRESSED OR
IMPLIED, EXCEPT AS SET FORTH HEREIN. THERE IS NO WARRANTY OF MERCHANTABILITY
AND THERE ARE NO WARRANTIES OF FITNESS FOR ANY PARTICULAR PURPOSE. IN NO
EVENT SHALL STRYKER BE LIABLE HEREUNDER FOR INCIDENTAL OR CONSEQUENTIAL
DAMAGES ARISING 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

• Improper usage of the Stryker Evacuation Chair can cause injury to the passenger or operator. Operate the Stryker
Evacuation Chair only as described in this manual.

• Do not modify the Stryker Evacuation Chair. Modifying the chair can cause unpredictable operation resulting in
injury to the passenger or operator. Modifying the chair will also void its warranty.

• Improper maintenance can cause injury or damage to the unit. Maintain the Stryker Evacuation Chair as described
in this manual. Use only Stryker approved parts and maintenance procedures. Using unapproved parts and
procedures could cause unpredictable operation and/or injury and will void the product warranty.

• Do not allow untrained helpers to assist in the operation of the Stryker Evacuation Chair. Untrained technicians/
helpers can cause injury to the passenger or themselves.

• An unlocked chair can fold during use, causing injury to the passenger or operator. Always make sure the chair is
locked in the unfolded position before use.

• To avoid injury, always verify the lift handles are locked in place before using them to lift the chair.

• Always use all restraint straps to secure the passenger on the chair. An unrestrained passenger may fall from the

chair and be injured.

• Never leave a passenger unattended on the chair or injury could result. Hold the chair securely while a passenger
is on the chair.

• The Stryker Evacuation Chair is not recommended for use with suspected cervical, spinal, or fracture injuries.

• To avoid injury when a passenger weighing more than 200 pounds is on the chair, use a minimum of two operators

to transport on stairs. If more people are required to safely control the chair, see page 1-25 for the proper
positioning of each helper.

• Only use the wheel locks during passenger transfer or without a passenger on the chair. Tipping could occur if
the chair is moved while wheel locks are applied, resulting in injury to the passenger or operator and/or damage
to the chair.

• Never use a wheel lock on a chair with excessively worn wheels. Using a wheel lock on a wheel with less than a
5” diameter could compromise the holding ability of the wheel lock, possibly resulting in injury to the passenger or
operator and/or damage to the chair or other equipment.

• To avoid injury, always verify the Stair-TREAD™ system is securely locked in place before transporting the
passenger.

• Water, ice and debris on the stairs can affect operator footing and proper operation of the Stair-TREAD™ system.
To avoid injury, clear the path or consider an alternate route.

• Condensation, water, ice and/or debris on the Stair-TREAD™ system can cause unpredictable performance,
resulting in a sudden change in the weight the operators must support. To avoid injury, and to aid proper operation
of the Stair-TREAD™ system, ensure the belts are clean and dry before transporting the passenger.

• Never lubricate the Stair-TREAD™ system. Lubrication on the system can cause inconsistent operation possibly
resulting in injury to the passenger or operator.

• To avoid injury to the operators and/or the passenger, operators should never attempt to transport passenger loads
greater than what they can safely lift.

• Do not sand the track teeth. Deformation of the teeth can cause unpredictable chair performance resulting in injury
to the operators and/or passenger.

English

CAUTION

• Casters are not suitable for all surfaces. Caution should be used at all times.

• Wheel locks are only intended to help prevent the empty chair from rolling while unattended and to aid in passenger

transfer. The wheel lock may not provide sufficient resistance on all surfaces or under loads.

• Release the red track release bar before clicking the Stair-TREAD™ system into the locked position. Failure to follow
this procedure could result in the track failing to lock. Always verify the Stair-TREAD™ system is locked by trying
to fold it before descending stairs.

USING RESTRAINT STRAPS - CONTINUED

• To lengthen the restraint, grasp the buckle, turn it at an angle to the webbing and pull it out. A hemmed tab at
the end of the webbing prevents the buckle from coming off the strap.

• To shorten the restraint, grasp the hemmed tab and pull the webbing back through the buckle until the required
tightness is achieved.

• When the chair is put into service, open the restraints and place them at either side of the chair until the passenger
is positioned on the seat. Lengthen the restraint, buckle it around the passenger and shorten it until the required
tightness to properly secure the passenger is achieved.

• To open the restraint, press the tabs on the side of the buckle to release the buckle and pull the tang out of the
receiver.

• To close the restraint, push the tang into the receiver until a “click” is heard.

• Whenever a restraint is buckled on a passenger, the attendant should verify the tang is locked and the extra

webbing is not tangled in the chair 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.

English

Operation Guide

TRANSPORTING THE PASSENGER DOWN STAIRS - CONTINUED

7. Both operators - Maintaining the angle, guide the Stryker
Evacuation Chair over the edge of the stairs, allowing the Stair­TREAD™ system to engage the first step.

8. Both operators - Glide down the stairs until the treads are level
across the edges of two or three steps.

9. Head end operator - Apply slight downward pressure on the
extendable upper control handle while the foot end operator
applies slight upward pressure on the foot end lift handles to
keep the chair from rocking forward as it glides down the stairs.

WARNING

• The Stair-TREAD™ system may not work the same on all
stair surfaces and in all environmental conditions. Based on
conditions, varying amounts of resistance may be encountered.
Avoid getting dirt or other obstructions inside the tracks. Water, ice
and/or debris on the stairs can affect operator footing and proper
operation of the Stair-TREAD™ system. To avoid injury, clear the
path or consider an alternate route. Condensation, water, ice and/
or debris on the Stair-TREAD™ system can cause unpredictable
performance, resulting in a sudden change in the weight the
operators must support.

• To avoid injury, and to aid proper operation of the Stair-TREAD™
system, ensure the belts are clean and dry before transporting the
passenger.

• To avoid injury to the operators and/or the passenger, operators
should never attempt to transport passenger loads greater than
what they can safely lift.

Figure 24 - Transporting down the stairs

10. Foot end operator (if necessary) - when the track reaches the
last step, release the front handles. Head end operator - allow the
chair to tip forward until all four wheels are on the ground. Roll
the chair as described on page 1-18.

11. To fold the Stair-TREAD™ system, pull the red track release bar
toward the black cross bar and fold the track up toward the chair.
Verify the Stair-TREAD™ system is locked in place.

Figure 25 - “Resting position”

CAUTION

Release the red track release bar before clicking the Stair-TREAD™
system into the locked position. Failure to follow this procedure could
result in the track failing to lock. Always verify the Stair-TREAD™
system is locked by trying to fold it before descending stairs.

If, while descending the stairs, either operator needs to pause or rest,
tilt the chair forward just enough to allow the rear wheels to rest in
the crook of the stair. To continue down the stairs from the resting
position, the head end operator exerts slight downward pressure on
the upper control handle while the foot end operator provides slight
upward pressure to tilt the chair back and engage the Stair-TREAD™
system.

Figure 31 - Wheel Locks

To activate the wheel locks:

1. Press down on the pedals (A) until they stop.

2. To release the wheel locks, depress the upper face of the pedal with your foot or lift up with your toe under the
pedal. The upper portion of the pedal will rest against the chair frame when the wheel lock is released.

WARNING

• Only use wheel locks during passenger transfer or without a passenger on the chair. Tipping could occur if the
chair is moved while the wheel locks are applied, resulting in injury to the passenger or operator and/or damage
to the chair.

• Wheel locks are only intended to help prevent the empty chair from rolling while unattended, and to aid in
passenger transfer. A wheel lock may not provide sufficient resistance on all surfaces or under loads.

• Never leave a passenger unattended on the chair or injury could result. Hold the chair securely while a passenger
is on the chair.

• Never use a wheel lock on a chair with excessively worn wheels. Using a wheel lock on a wheel with less than a
5” diameter could compromise the holding ability of the wheel lock, possibly resulting in injury to the passenger or
operator and/or damage to the chair or other equipment.
