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.

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.
