2 SAFETY 2 Safety The Safety section contains important information for the safe operation and use of this product. 2.1 General Guidelines ! WARNING DO NOT use this product or any available optional equipment without first completely reading and understanding these instructions and any additional instructional material such as owner’s manuals, service manuals or instruction sheets supplied with this product or optional equipment.
2 SAFETY 2.2 Operation Information Setup WARNING Before using the scooter, verify that the motor is plugged into the harness. Transport WARNING DO NOT operate on roads, streets or highways. TIE-DOWN RESTRAINTS AND SEAT RESTRAINTS Powered scooter users should NOT be transported in vehicles of any kind while in the powered scooter.
2 SAFETY WARNING STAIRWAYS AND ESCALATORS DO NOT attempt to move an occupied powered scooter between floors using a stairway. Use an elevator to move an occupied powered scooter between floors. If moving a powered scooter between floors by means of a stairway, the occupant MUST be removed and transported independently of the powered scooter. Extreme caution is advised when moving an unoccupied powered scooter up or down the stairs.
2 SAFETY Repair or Service Information WARNING Scooters should be examined during maintenance for signs of corrosion (water exposure, incontinence, etc.). Electrical components damaged by corrosion should be replaced IMMEDIATELY. Set-up of the Electronics Control Unit is to be performed only by a qualified technician. The final adjustments of the controller may affect other activities of the scooter. Damage to the equipment could occur if improperly set-up or adjusted.
2 SAFETY To assure stability and proper operation of your powered scooter, you MUST, at all times, maintain proper balance. Your powered scooter has been designed to remain upright and stable during normal daily activities. Many activities require the scooter owner to reach, bend and transfer in and out of the powered scooter. These movements cause a change to the normal balance, the center of gravity, and the weight distribution of the powered scooter.
2 SAFETY WARNING When negotiating ramps, if the throttle control lever is released while in the forward motion, the powered scooter will roll back approximately one foot before the brake engages. If the throttle control lever is released while in the reverse motion, the powered scooter will roll back approximately three feet before the brake engages. DO NOT attempt to drive over curbs or obstacles. Doing so may cause your powered scooter to turn over and cause bodily harm and/or damage to the scooter.
2 SAFETY Storage WARNING Scooters that are used by incontinent users and/or are frequently exposed to water may require replacement of electrical components more frequently. RAIN TEST Invacare has tested its powered scooters in accordance with ISO 7176 “Rain Test”. This provides the end user or his/her attendant sufficient time to remove his/her powered scooter from a rain storm and retain powered scooter operation. DO NOT leave the powered scooter in a rain storm of any kind.
2 SAFETY Electrical and Grounding Ꮨ WARNING Check to ensure that all electrical connections are secure at all times. GROUNDING INSTRUCTIONS DO NOT, under any circumstances, cut or remove the round grounding prong from any plug used with or for Invacare products. Some devices are equipped with three-prong (grounding) plugs for protection against possible shock hazards.
2 SAFETY Weight Limitation WARNING The weight limitation is 300 lbs. Disposal WARNING This product has been supplied from an environmentally aware manufacturer that complies with the Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/CE. This product may contain substances that could be harmful to the environment if disposed of in places (landfills) that are not appropriate according to legislation.
2 SAFETY The sources of radiated EMI can be broadly classified into three types: 1. Hand-held Portable transceivers (transmitters-receivers with the antenna mounted directly on the transmitting unit. Examples include: citizens band (CB) radios, “walkie talkie”, security, fire and police transceivers, cellular telephones, and other personal communication devices). Some cellular telephones and similar devices transmit signals while they are ON, even when not being used. 2.
2 SAFETY WARNING 1) DO NOT operate hand-held transceivers (transmitters receivers), such as citizens band (CB) radios, or turn ON personal communication devices, such as cellular phones, while the powered wheelchair is turned ON; 2) Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming close to them; 3) If unintended movement or brake release occurs, turn the powered wheelchair OFF as soon as it is safe; 4) Be aware that adding accessories or components, or modifying the

5 INSPECTION 5 Inspection 5.1 Safety Inspection Checklists Every six months take your powered scooter to a qualified technician for a thorough inspection and servicing. Regular cleaning will reveal loose or worn parts and enhance the smooth operation of your powered scooter. To operate properly and safely, your powered scooter must be cared for just like any other vehicle. Routine maintenance will extend the life and efficiency of your powered scooter.
5 INSPECTION Inspect/Adjust Initially ❑ Ensure powered scooter drives straight (no excessive drag or pull to one side). ❑ Check frame for damage and corrosion. ❑ Ensure that the brake release lever is easy to engage/disengage. ❑ Ensure that tiller adjustment mechanism engages and disengages properly and securely. ❑ Ensure that the scooter stops completely when throttle is released (i.e., does not continue to roll as if the throttle is activated). ❑ Clean upholstery and armrests.
5 INSPECTION Inspect/Adjust Monthly ❑ Check brake for binding or interference with travel. ❑ Inspect front wheel/fork assembly for proper tension by spinning the wheel. The front wheel should come to a gradual stop. ❑ Tighten locknut if the front wheel wobbles noticeably or loosen locknut if the wheel binds to a stop. ❑ Inspect seat swivel for release and engagement (seat locks into the determined swivel positions). ❑ Inspect the seat positioning strap for signs of wear.
