II Safety Precautions IMPORTANT: BEFORE USING YOUR Metro Power III, PLEASE READ AND UNDERSTAND THE FOLLOWING SAFETY PRECAUTIONS. Maintenance Protect your Metro Power III by having it serviced regularly. Whenever any part of your wheelchair is not functioning properly, a hazardous situation could result. Only excellent condition is acceptable where safety is concerned. Periodic inspection, adjustment, and replacement of worn parts will provide many years of superb performance.
Warning: Do not enter or exit the wheelchair without first turning the wheelchair power switch OFF, and ensuring that the drive engagement levers are engaged, to prevent wheelchair movement. Warning: Operate only with anti-tippers in place. Warning: Disengaging the rear wheel levers will also disengage the electromechanical park brakes and allow the wheelchair to roll. Warning: Do not lean over the top of the wheelchair back. This could cause the wheelchair to tip.
Warning: Do not switch programmer into PROGRAM mode while wheelchair is moving. Warning: Do not disconnect the wheelchair batteries while the programmer is connected to the integral controller. Warning: Do not use any adaptive control devices other than those provided or recommended by Graham-Field. Warning: Do not connect accessories to the batteries; it will decrease driving range and shorten battery life. Do not connect ANYTHING to only one battery; this will cause premature battery failure.
Electromagnetic interference (EMI) from radio wave sources It is very important that you read this information regarding the possible effects of electromagnetic interference on your Everest & Jennings Metro Power III power wheelchair. Powered wheelchairs may be susceptible to electromagnetic interference (EMI), which is interfering electromagnetic (EM) energy emitted from sources such as radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios, and cellular telephones.
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.
III Handling Tips The Everest & Jennings Metro Power III been designed and engineered to perform as a stable and well balanced unit when used for its intended purpose. However, it is possible to tip the Metro Power III over if it is used improperly. We urge you to learn the characteristics of your wheelchair. It is most important to learn safe methods to perform the daily activities basic to your lifestyle.
Reaching / bending forward or sideward Warning: Do not attempt to reach objects if you are required to move forward in the seat. Do not attempt to retrieve objects from the floor if you must reach down between your knees. Do not shift your weight in the direction that you are reaching and/or bending; this could cause the wheelchair to tip. 1. Maneuver the wheelchair as close as possible to the object you wish to reach. 2. Rotate both casters fully forward.
Always inspect the ramp for hazards such as holes, slippery or uneven surfaces, etc. before starting up or down. If you can not see the entire ramp, ask someone to inspect it for you. Ascent Lean the upper part of your body slightly forward as you ascend the incline. If it becomes necessary to stop on the incline, avoid any sudden forward movement as you resume climbing; this could cause tipping.
IV Getting Started The Metro Power III is designed to provide the highest degree of independence and mobility. The tested range of the Metro Power III is approximately 16 miles on a hard level surface (tested with a 250 lb. user and fully charged U1 size batteries). Actual range will vary according to your weight, the amount of start/stop driving, ambient temperature, and the terrain on which you travel with your wheelchair.
Power Drive System The Metro Power III power drive system consists of two independent rear drive wheels, an integral controller, independent, direct drive right and left motors, and two twelve volt batteries (not supplied by Graham-Field) that provide power.
