SECTION 1—GENERAL GUIDELINES SECTION 1—GENERAL GUIDELINES WARNING SECTION 1 - GENERAL GUIDELINES contains important information for the safe operation and use of this product. The information in this manual pertains to wheelchairs without powered seating systems only. Refer to the powered seating system service manual for specific information about servicing those systems.
SECTION 1—GENERAL GUIDELINES ALWAYS keep hands and fingers clear of moving parts to avoid injury. NEVER leave an unoccupied wheelchair unattended on an incline. DO NOT engage or disengage the motor locks until the power is in the off position. DO NOT tip the wheelchair without assistance. Tire Pressure Ensure the wheelchair has the proper tire pressure (P.S.I.) before use. DO NOT overinflate the tires. Failure to follow these recommendations may cause the tire to explode and cause bodily harm.
SECTION 2—SAFETY/HANDLING OF WHEELCHAIRS SECTION 2—SAFETY/HANDLING OF WHEELCHAIRS Pinch Points WARNING TDX and TDX SP Wheelchairs Only - Pinch points exist between the headtube cap and walking beam.

SECTION 3—EMI INFORMATION SECTION 3—EMI INFORMATION WARNING CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE EFFECTS OF ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED WHEELCHAIR.
SECTION 3—EMI INFORMATION WARNING Powered Wheelchair Electromagnetic Interference (EMI) Because EM energy rapidly becomes more intense as one moves closer to the transmitting antenna (source), the EM fields from hand-held radio wave sources (transceivers) are of special concern. It is possible to unintentionally bring high levels of EM energy very close to the powered wheelchair's control system while using these devices. This can affect powered wheelchair movement and braking.
SECTION 4—SAFETY INSPECTION/TROUBLESHOOTING SECTION 4—SAFETY INSPECTION/ TROUBLESHOOTING Safety Inspection Checklist NOTE: Initial adjustments should be made to suit the end userʹs personal body structure needs and preference.
