The words WWAARRNNIINNGG,CCAAUUTTIIOONN, and NNOOTTEE carry special meanings and should be carefully reviewed.
WWAARRNNIINNGG
Alerts the reader about a situation which, if not avoided, could result in death or serious injury. It may also describe
potential serious adverse reactions and safety hazards.
CCAAUUTTIIOONN
Alerts the reader of a potentially hazardous situation which, if not avoided, may result in minor or moderate injury to the
user or patient or damage to the product or other property. This includes special care necessary for the safe and effective
use of the device and the care necessary to avoid damage to a device that may occur as a result of use or misuse.
NNoottee -- Provides special information to make maintenance easier or important instructions clearer.
SSuummmmaarryy ooff ssaaffeettyy pprreeccaauuttiioonnss
Always read and strictly follow the warnings and cautions listed on this page. Service only by qualified personnel.
WWAARRNNIINNGG
• Always make sure that the chair is locked in the unfolded position before use. An unlocked chair may fold during use.
• Always use all restraint straps to secure the occupant on the product. An unrestrained occupant may fall from the
product.
• Do not apply a wheel lock when an occupant is on the product or when you move the product to avoid the risk of tipping.
• Always avoid getting dirt or other obstructions inside the tracks. The SSttaaiirr--TTRREEAADD 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 SSttaaiirr--TTRREEAADD
system. To avoid injury, clear the path or consider an alternate route. Condensation, water, ice, or debris on the SSttaaiirr--
TTRREEAADD system can cause unpredictable performance that results in a sudden change in the weight the operators must
support.
• Do not allow untrained helpers to assist in the operation of the product. Untrained helpers may cause injury to the
occupant or themselves.
• Always transport an occupant weighing more than 200 lb on stairs with a minimum of two trained operators.
• Do not attempt to transport occupant loads greater than what you can safely lift.
• Do not use the chair with suspected cervical, spinal, or fracture injuries.
• Do not allow the occupant to stand on the footrest to avoid injury or equipment damage.
• Always lock the SSttaaiirr--TTRREEAADD system in position before you transport an occupant.
• Always lock the lift handles in position before you use the lift handles to lift the chair.
• Always clean and dry the SSttaaiirr--TTRREEAADD system before you transport an occupant.
• Do not leave an occupant unattended. Hold the product while an occupant is on the product.
• Do not install or apply a wheel lock on a product with worn wheels that are less than 5 in. diameter.
• Always make sure that you secure all tubes, regulators, and accessories for the oxygen bottle to prevent interference
with the tracks, wheels, or other mechanisms of the chair.
• Always properly clean or dispose of contaminated chair components to avoid risk of exposure to blood borne pathogens
and injury to the occupant or 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.

CCAAUUTTIIOONN
• Improper usage of the product can cause injury to the occupant 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 occupant or operator. Modifying the product also voids its warranty.
• Always release the red track release bar before you click the SSttaaiirr--TTRREEAADD system into the locked position. Try to fold
the chair before you descend the stairs to make sure that the SSttaaiirr--TTRREEAADD system is locked.
• Always use caution when you use casters. Casters are not suitable for all surfaces.
• The elastic oxygen bottle holder is for use only with Stryker Evacuation Chairs and SSttaaiirr--PPRROO® Stair Chairs. Use only
D-size oxygen bottles with the elastic oxygen bottle holder.
• Always properly secure the oxygen bottle and oxygen bottle accessories so they do not interfere with the operation of
the chair.
• Always make sure that you secure the oxygen bottle to the elastic oxygen bottle holder using the red VVeellccrroo® strap.
•Always make sure that you secure the oxygen bottle in the elastic oxygen bottle holder and that the regulator valve of
the oxygen bottle does not protrude from the width of the chair.
• Always remove the oxygen bottle from the elastic oxygen bottle holder before you attempt to fold or store the 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

Buckle one restraint across the occupant’s chest and the other across the occupant’s lap. Buckle the ankle restraint across
the occupant’s legs.
Secure restraint straps to the product in the required attachment locations (Figure 3 and Figure 4). Restraint strap
attachment locations should provide strong anchorage and proper restraint position. Do not allow restraint straps to
interfere with equipment or accessories. Buckle restraint straps when the chair is not in use.
Open the restraint straps and place them at either side of the chair while you position the occupant on the seat. Lengthen
the restraint straps, buckle them around the occupant, and shorten them to tighten.
• To open the restraint strap, press the tabs on the side of the buckle receiver. This allows you to release the buckle latch
plate and pull it out of the receiver.
• To close the restraint strap, push the latch plate into the receiver until you hear a click.
• To lengthen the restraint strap, grasp the buckle latch plate, turn it at an angle to the webbing, then pull it out. A hemmed
tab at the end of the webbing prevents the latch plate from coming off of the strap.
• To shorten the restraint strap, grasp the hemmed tab and pull the webbing back through the latch plate to tighten.
When you buckle a restraint strap around an occupant, secure the latch plate and remove any loose webbing from the
chair.
