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

• Do not modify the Stair-PRO® Stair Chair. Modifying the chair can cause unpredictable operation resulting in injury

to the patient or operator. Modifying the chair will also void its warranty.

• Do not allow untrained helpers to assist in the operation of the Stair-PRO® Stair Chair. Untrained technicians/

helpers can cause injury to the patient or themselves.

• An unlocked chair can fold during use, causing injury to the patient 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 patient on the chair. An unrestrained patient may fall from the chair

and be injured.

• Do not push the Model 6252 with the upper control handle in the fully extended position. Pushing the chair with

the handle in the fully extended position may cause the chair to tip when obstacles are encountered.

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

the chair.

• The Stair-PRO® Stair Chair is not recommended for use with suspected cervical, spinal, or fracture injuries.

• To avoid injury, transporting the patient on stairs requires a minimum of two operators. If more people are required

to safely control the chair, use the chart on page 29 as reference for proper positioning of the helpers.

• Only use the wheel locks during patient transfer or without a patient on the chair. Tipping could occur if the chair

is moved while wheel locks are applied, resulting in injury to the patient 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 (Model 6252) or a 6” diameter (Models 6250/6251) could compromise the holding ability of the wheel
lock, possibly resulting in injury to the patient or operator and/or damage to the chair or other equipment.

• To avoid injury, always verify the Stair-TREAD™ system on the Model 6252 is securely locked in place before

transporting the patient.

• 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 patient.

• Never lubricate the Stair-TREAD™ system. Lubrication on the system can cause inconsistent operation possibly

resulting in injury to the patient or operator.

• To avoid injury to the operators and/or the patient, operators should never attempt to transport patient loads greater

than what they can safely lift.

• Use any appropriate personal safety equipment (goggles, respirator, etc.) to avoid the risk of inhaling contagion. Use

of power washing equipment can aerate contamination collected during the use of the cot.

CAUTION

• Improper usage of the Stair-PRO® Stair Chair can cause injury to the patient or operator. Operate the Stair-PRO

Stair Chair only as described in this manual.

• Improper maintenance can cause injury or damage to the unit. Maintain the Stair-PRO® Stair 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.

• 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 patient

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.

Operation Guide

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 patient

is positioned on the seat. Lengthen the restraint, buckle it around the patient and shorten it until the required
tightness to properly secure the patient 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 patient, 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.

PROPER LIFTING TECHNIQUES

When lifting the Stair-PRO® Stair Chair and patient, remember these five basic guidelines:

• Keep your hands close to your body.

• Keep your back straight.

• Coordinate your movements with your partner and lift with your legs.

• Avoid twisting.

• Always operate the Stair-PRO® Stair Chair as described in this manual.

safely control the chair, use the chart on page 29 as reference for proper positioning of the helpers. To avoid injury,
always verify the lift handles are locked in place before using them to lift the chair.

Models 6250 and 6251

1. Foot end operator - descend in front of the Stair-PRO® Stair Chair.

2. Head end operator - approach the stairs squarely.

3. Foot end operator - push each red foot end lift handle button and pull out each handle until it stops. Release the
button and verify the handle is locked securely in position.

4. Head end operator - unfold the head end lift handles and face down the stairs.

5. Foot end operator - either face backward for improved patient monitoring or forward for an improved view of the
stairs and easier maneuvering around obstacles.

Note: Although the front operator can face either direction while lifting and carrying,
any applicable protocols for carrying chairs should be followed.

6. Both operators - simultaneously lift the chair, using the head and foot end lift handles and following the
proper lifting techniques (see page 19). Carry the chair slowly down the stairs, avoiding any obstructions.

TRANSPORTING THE PATIENT DOWN STAIRS - CONTINUED

Model 6252 - Continued

7. Both operators - Maintaining the angle, guide the Stair-PRO® Stair
Chair over the edge of the stairs, allowing the Stair-TREAD™
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 patient.

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

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 37 - Wheel Locks

(6250 Shown)

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 patient transfer or without a patient on the chair. Tipping could occur if the chair is
moved while the wheel locks are applied, resulting in injury to the patient 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 patient
transfer. A wheel lock may not provide sufficient resistance on all surfaces or under loads.

• Never leave a patient unattended on the chair or injury could result. Hold the chair securely while a patient 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 (Model 6252) or a 6” diameter (Models 6250/6251) could compromise the holding ability of the wheel
lock, possibly resulting in injury to the patient or operator and/or damage to the chair or other equipment.
