Summary of safety precautions
Always read and strictly follow the warnings and cautions listed on this page. Service only by qualified personnel.
WARNING
• Always make sure that the chair is locked in the unfolded position before use. An unlocked chair may fold during
use.
• Do not use the chair with suspected cervical, spinal, or fracture injuries.
• Do not leave an occupant unattended. Hold the product while an occupant is on the product.
• Always use all restraint straps to secure the occupant on the product. An unrestrained occupant may fall from the
product.
• 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 you encounter obstacles.
• Always lock the Model 6252 Stair-TREAD system in position before you transport an occupant.
• Avoid getting dirt or other obstructions inside the tracks. The Stair-TREAD system may not work the same on all
stair surfaces and in all environmental conditions. Based on conditions, you may encounter varying amounts of
resistance. Water, ice, 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, or debris on the
Stair-TREAD system can cause unpredictable performance that results in a sudden change in the weight that the
operators must support.
• Always clean and dry the Stair-TREAD system before you transport an occupant.
• Do not attempt to transport occupant loads greater than what you can safely lift.
• Do not install or apply a wheel lock on a product with worn wheels that are less than 6 in. diameter.
• Always lock the lift handles in position before you use the handles to tip the chair back.
• Always make sure that you secure all tubes, regulators, and ancillary accessories for the oxygen bottle to prevent
interference with the tracks, wheels, or other mechanisms of the stair chair.
• Failure to properly clean or dispose of contaminated stair chair components will increase the risk of exposure to
blood borne pathogens and may cause injury to the patient or the operator.
• Always use any appropriate personal protective equipment while power washing to avoid inhaling contagion. Power
washing equipment may aerate contamination.
• Always wipe the product with clean water and dry after cleaning. Some cleaning products are corrosive in nature
and may cause damage to the product. Failure to properly rinse and dry the product leaves a corrosive residue on
the surface of the product and may cause premature corrosion of critical components.
CAUTION
• Improper usage of the product can cause injury to the patient or operator. Operate the product only as described in
this manual.
• Do not modify the product or any components of the product. Modifying the product can cause unpredictable
operation resulting in injury to patient or operator. Modifying the product also voids its warranty.
• Always clear any obstacles that may interfere and cause injury to the operator or patient before operating the
product.
• Always use caution when using casters. Casters are not suitable for all surfaces.
• Always release the red track release bar before you click the Stair-TREAD system into the locked position. Try to
fold the chair before you descend the stairs to make sure that the Stair-TREAD system is locked.
• The elastic oxygen bottle holder is for use only with RUGGED® Stair-PRO stair chairs and D-size oxygen bottles.
• Failure to properly secure the oxygen bottle and oxygen bottle accessories could interfere with the operation of the
stair chair.
• Always make sure that you secure the oxygen bottle to the elastic oxygen bottle holder using the red Velcro strap.

Summary of safety precautions
CAUTION (CONTINUED)
• Always make sure that the oxygen bottle is secure in the elastic oxygen bottle holder and that the regulator valve of
the oxygen bottle does not protrude from the width of the stair chair.
• Always remove the oxygen bottle from the elastic holder before attempting to fold or store the stair chair.
• Do not steam clean or ultrasonically clean the product.
• Do not exceed 180 °F (82 °C) as the maximum water temperature.
• Do not exceed 1500 psi (130.5 bar) as the maximum water pressure. If you are using a hand held wand to wash the
product, keep the pressure nozzle at a minimum of 24 in. (61 cm) from the product.
• Always allow to air dry.
• Do not clean, service, or perform maintenance while the product is in use.

WARNING
• Always transport the occupant on stairs with a minimum of two operators.
• Always lock the lift handles in position before you use the lift handles to lift the chair.
• Always lock the Model 6252 Stair-TREAD system in position before you transport an occupant.
• Avoid getting dirt or other obstructions inside the tracks. The Stair-TREAD system may not work the same on all
stair surfaces and in all environmental conditions. Based on conditions, you may encounter varying amounts of
resistance. Water, ice, 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, or debris on the
Stair-TREAD system can cause unpredictable performance that results in a sudden change in the weight that the
operators must support.
• Always clean and dry the Stair-TREAD system before you transport an occupant.
• Do not attempt to transport occupant loads greater than what you can safely lift.
CAUTION
Always release the red track release bar before you click the Stair-TREAD system into the locked position. Try to fold
the chair before you descend the stairs to make sure that the Stair-TREAD system is locked.

1. Roll the chair to the stairs and align it with the edge of the first step.
2. Foot end operator: Push the red release buttons to extend the foot end lift handles and pull the handles out until
they stop. Release the buttons to lock the handles.
3. Head end operator: Use one hand to pull the red upper control handle release cable. Use the other hand to pull up
and fully extend the handle. Release the cable and make sure that 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
make sure that both sides of the Stair-TREAD system are locked by trying to fold it back up.
5. Operators face each other while you descend the stairs.
6. Head end operator: Tilt the chair back just far enough to allow the Stair-TREAD system to contact the floor.
7. Both operators - Maintaining the angle, guide the chair over the edge of the stairs. Allow the Stair-TREAD system to
connect with 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.
