Page 4: Safety Precautions
IMPORTANT: BEFORE usING YOuR Metro Power III, PLEAsE READ AND uNDERsTAND THE FOLLOWING sAFETY PRECAuTIONs. 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. - Page 5 Warning: Disengaging the rear wheel levers will also disengage the electromechani- cal 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: Before leaning or reaching forward: To reduce the risk of tipping, sit back in the seat and rotate casters fully toward front of wheelchair.
- Page 6 Warning: The use of non-Graham-Field replacement parts could create a hazardous condition, which could result in serious injury. Warning: standard weight capacity for the Metro Power III wheelchair is 300 lb. (136 kg). Warning: Do not tow any loads or “piggyback” passengers or heavy packages.

Page 7: Electromagnetic Interference (Emi) From Radio Wave Sources
(HAM) transmitters, two-way radios, and cellular telephones. The interference (from radio wave sources) can cause the powered wheelchair to release its brakes, move by itself, or move in unintend- ed directions. It can also permanently damage the powered wheelchair’s control system. The intensity of the interfering EM energy can be measured in volts per meter (V/m). -
Page 8: Important Information
(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 brak- ing. -
Page 9: Handling Tips
Proper balance is the key to maintaining the stability of your wheelchair. Reaching, bending, and transferring to or from a wheelchair will change the weight distribution and center of gravity of you and your wheelchair. When performing such activities, do so as instructed in the following para- graphs to avoid tipping the wheelchair. -
Page 10: Ramps And Inclines
Warning: Do not lean over the back upholstery; this could cause the wheelchair to tip. 1. Maneuver the wheelchair as close as possible to the object. The rear wheels will limit how close you can get. 2. Rotate both casters fully forward. If otherwise, go forward and then back the wheelchair toward the object to swing the casters fully forward. -
Page 11: Curbs And Steps
If possible, lean slightly backward to increase stability. It is critical to keep the wheelchair under control at all times. Descent should be made slowly and steadily, allowing the wheelchair’s control system to maintain a safe speed. Upon stopping, electro- mechanical park brakes will engage to prevent the wheelchair from rolling. -

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. As you become more acquainted with your wheelchair, its range and performance capa- bilities will become more apparent. -
Page 13: Power Drive System
The JOYSTICK controls the speed and direction of wheelchair travel. The further you push the joy- stick from the rest position the faster your wheelchair will move. When the joystick is returned to the neutral (center) position or released, the control system will bring the wheelchair to a smooth stop. -
Page 14: Battery Gauge
The battery gauge gives you a more accurate reading about a minute after you start driving the wheelchair. The battery gauge also provides a diagnostics display when wheelchair electrical system problems occur. See TROUBLESHOOTING for a description of the battery gauge diagnostics. -
Page 15: Operating Instructions
2. Engage the rear wheels by turning the drive engagement levers (on the tops of the motors at rear of wheelchair) inward, toward the battery boxes; see picture above. 3. With the joystick in neutral, turn wheelchair power on (press the ON/OFF switch). The battery gauge will blink and then turn on after a second. -
Page 16: Adjustments
The Metro Power III offers several adjustments to enhance driving ease and comfort. Adjustments should be performed with wheelchair power off and the wheelchair unoccupied.

Page 32: Check Tires
If the nut is too loose, the caster will flutter or shimmy; if the nut is too tight, the wheelchair will be difficult to steer. If the caster stem requires adjustment, or the caster stem bearing requires replacement, visit a qualified Graham-Field dealer. Ensure that stems are firmly attached to forks, and that forks and stems are not bent. - Page 33 These signs indicate that the bearings are becoming worn and may require replacement. The caster bearings should be inspected every six months and replaced as needed. This should be performed by an Graham-Field dealer. Metro Power III Owner’s Manual GF0600059RevB06, November 2006...

Old batteries discharge much more quickly than new batteries under the same driving conditions. This results in a decrease in the distance the wheelchair can travel before batteries need to be charged. This decrease is often misinterpreted as a problem with the wheelchair system, when in fact the bat- teries have simply reached the end of their useful life and should be replaced. - Page 35 Red & yellow None Charge battery if possible; controller and electrical system OK. bars lit Red bars only None Low batteries; controller and electrical system OK.
