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.

WARNING
• Always use all restraint straps to secure the patient on the chair. An unrestrained patient may fall from the chair
and be injured.
• Only use the 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.
• Condensation, water, ice and/or debris on the Model 6252 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.

Figure 10-18 - Attaching the leg strap
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.

Figure 20 - Transporting the Patient on a Model 6252
CAUTION
Casters are not suitable for all surfaces. Caution should be used at all times.
Model 6250
To roll the Model 6250 Stair-PRO® over flat surfaces, use either the locking rear lift handles (if equipped), or the
backrest tube to tip the chair back. Once the chair is tipped back, use either the head end lift handles or the backrest
tube to roll and guide the chair. Lift the chair over and around obstructions with the head end and foot end lift handles.
Model 6251
To roll the Model 6251 Stair-PRO® over flat surfaces, push and guide the chair from the rear of the patient, using either
the head end lift handles or the backrest tube. Lift the chair over and around obstructions with the head end and foot
end lift handles.
Model 6252
To roll the Model 6252 Stair-PRO® over flat surfaces, follow the same method as above for the Model 6251. In addition
to the head end lift handles, the extendable upper control handle can be used in any position to roll and guide the chair.
Extend the upper control handle by pulling the red release cable with one hand, and pulling up on the control handle
with the other. Release the cable to lock the handle in either the intermediate or fully extended position. Lift the chair
over and around obstructions with the head end and foot end lift handles.
WARNING
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.

TRANSPORTING THE PATIENT DOWN STAIRS - CONTINUED
Model 6252
WARNING
• To avoid injury, always verify the Stair-TREAD™ system on the
Model 6252 is locked in place before transporting the patient.
• 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.
• To avoid injury, always verify the lift handles are locked in place
before using them to lift the chair.
1. Roll the chair to the stairs and align it squarely with the edge of
the first step.
2. Foot end operator - Extend the foot end lift handles by pushing
the red release buttons and pulling the handles out until they stop.
Release the buttons and verify the handles are locked.
3. Head end operator - Use one hand to pull the red upper control
handle release cable while using the other hand to pull up and
fully extend the handle. Release the cable and verify the handle
is locked on both sides in the fully extended position.
4. Head end operator - Squeeze the red track release bar against
the black cross tube. Relax your grip on the release bar and
forcefully pull the Stair-TREAD™ system to the fully extended
position until both sides lock securely. Always verify both sides of
the Stair-TREAD™ system are locked by trying to fold it back up.
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.

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.

10. Foot end operator - 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 20.
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.

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.

TRANSPORTING THE PATIENT UP STAIRS
WARNING
• 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.
• To avoid injury, always verify the lift handles are locked in place
before using them to lift the chair.
All Models
1. Roll the chair to the bottom of the stairs with the patient’s back
to the stairs.
2. Foot end operator - extend the foot end lift handles by pushing the
red buttons and pulling the handles until they stop. Release the
button and verify the handle is locked.
3. Head end operator - unfold the head end lift handles.
4. The foot end operator faces up the stairs. The head end operator
may either face backward for improved patient monitoring or
forward for an improved view of the stairs and easier maneuvering
around obstacles.
Note: Although the head end operator can face either direction
while carrying, any applicable protocols for carrying chairs should
be followed.
5. Both operators - simultaneously lift the chair, using the head and
foot end lift handles and following proper lifting techniques (see
page 19). Carry the chair slowly up the stairs, avoiding any
obstructions.

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.
