m	11
Warning	11
Check all Allen screws that secure the footrest/raised footrest system to the wheelchair frame before using the wheelchair, especially if engaging in any contact sport.	11
Anti-tippers MUST be used at all times. When outdoors on wet, soft ground or on gravel surfaces, anti-tippers may not provide the same level of protection against tip over. Extra caution MUST be observed when traversing such surfaces. Inasmuch as the...	11
Engaging the wheel locks may not prevent the wheelchair from moving on all floor surfaces including those that may be wet or slick. ALWAYS exercise caution when transferring into or out of the wheelchair.	11
ALWAYS use the handrims for self-propulsion. Inasmuch as the handrims are an option on this wheelchair (you may order with or without the handrims), Invacare strongly recommends ordering the handrims as an additional safeguard for the wheelchair user.	11
DO NOT use the footplate as a platform when getting in or out of the wheelchair.	11

DO NOT attempt to lift a wheelchair by lifting on any removable (detachable) parts. Lifting by means of any removable (detachable) parts of the wheelchair may result in injury to the user or damage to the wheelchair.	17
ALWAYS check hand grips for looseness before using the wheelchair. If loose and/or worn, replace IMMEDIATELY.	17
Anti-tippers MUST be attached at all times. Inasmuch as the anti-tippers are an option on this wheelchair (you may order with or without the anti-tippers), Invacare strongly recommends ordering the anti-tippers as an additional safeguard for the whee...	17
DO NOT climb, go up, or down ramps or traverse slopes greater than 9°.	17
m	18
warning	18
Invacare strongly recommends proceeding down ramps or slopes slowly to avoid hard braking or sudden stops.	18
Be aware that carrying heavy objects on your lap while occupying the wheelchair may adversely affect the stability of the wheelchair, resulting in serious bodily injury to the user, damage to the wheelchair and surrounding property.	18
This wheelchair has been designed to accommodate one individual. If more than one individual occupies the wheelchair this may adversely affect the stability of the wheelchair, resulting in serious bodily injury to the user and passenger and damage th...	18
To assure stability and proper operation of your wheelchair, you MUST at all times maintain proper balance. Your wheelchair has been designed to remain upright and stable during normal daily activities as long as you DO NOT move beyond the center of ...	18
Virtually all activities which involve movement in the wheelchair have an effect on the center of gravity. Invacare recommends using seat positioning straps for additional safety while involved in activities that shift your weight.	18
DO NOT lean forward out of the wheelchair any further than stability will allow. Make sure casters are pointing in the forward position whenever you lean forward. This can be achieved by advancing the wheelchair and then reversing it in a straight line.	18
m	18
warning	18
DO NOT attempt to reach objects if you have to move forward in the seat or pick them up from the floor by reaching down between your knees.	18
The position of the footrest, camber tube, back angle, the tautness of the back upholstery as well as the user's condition are directly related to the wheelchair's stability. Any change to one or any combination of the five may cause the wheelchair t...	18
Many activities require the wheelchair owner to reach, bend and transfer in and out of the wheelchair. These movements will cause a change to the normal balance, the center of gravity, and the weight distribution of the wheelchair.	18
To determine and establish your particular safety limits, practice bending, reaching and transferring activities in several combinations in the presence of a qualified health-care professional before attempting active use of wheelchair.	18
Proper positioning is essential for your safety. When reaching, leaning, bending forward, it is important to use the front casters as a tool to maintain stability and balance.	18
• Lengthening the wheelbase will increase the stability and maintain standard maneuverability of wheelchair.	19
• Shortening the wheelbase will decrease the stability, increase the maneuverability and distribute additional weight onto the rear wheels.	19
Lengthening the Wheelbase	19
Reaching, Leaning and Bending - Forward	19
m	19
warning	19
DO NOT attempt to reach objects if you have to move forward in the seat or pick them up from the floor by reaching down between your knees.	19
Position the front casters so that they are extended as far forward as possible and engage wheel locks.	19
Reaching, Leaning - Backwards	19
m	19
warning	19
DO NOT lean over the top of the back upholstery. This will change your center of gravity and may cause you to tip over.	19
Position wheelchair as close as possible to the desired object. Point front casters forward to create the longest possible wheelbase. Reach back only as far as your arm will extend without changing your sitting position.	19
Reaching, Leaning, and Bending - Forward	20
4.3 Coping with Everyday Obstacles	20
Coping with the irritation of everyday obstacles can be alleviated somewhat by learning how to manage your wheelchair. Keep in mind your center of gravity to maintain stability and balance.	20
4.4 A Note to Wheelchair Assistants	20
When assistance to the wheelchair user is required, remember to use good body mechanics. Keep your back straight and bend your knees whenever tilting the wheelchair or traversing curbs, or other impediments.	20
m	20
warning	20
Do not attempt to lift a wheelchair by lifting on any removable (detachable) parts. Lifting by means of any removable (detachable) parts of a wheelchair may result in injury to the user or damage to the wheelchair.	20
Also, be aware of any removable (detachable) parts. These MUST NEVER be used to move the wheelchair or as lifting supports, as they may be inadvertently released, resulting in possible injury to the user and/or assistant(s).	20
When learning a new assistance technique, have an experienced assistant help you before attempting it alone.	20

m	21
warning	21
DO NOT tip the wheelchair without assistance	21
Do not let the wheelchair drop the last few inches to the ground. This could result in injury to the occupant.	21

5.3 Maintenance	28
Maintenance Safety Precautions	28
m	28
warning	28
After ANY adjustments, repair or service and before use, make sure all attaching hardware is tightened securely - otherwise injury or damage may occur.	28
Replace any labels that are missing, worn, or torn. Refer to Label Locations on page 12 for a listing of the labels and their locations	28
caution	28
DO NOT overtighten hardware attaching to the frame. This could cause damage to the frame tubing.	28
Suggested Maintenance Procedures	29
1. Before using your wheelchair, make sure all nuts and bolts are tight.	29
2. Check all parts for damage or wear and replace.	29
3. Check all parts for proper adjustment.	29
4. Keep quick/quad-release axles free of dirt and lint to ensure positive locking and proper operation. Refer to Adjusting Quick-Release Axles on page 63 or Adjusting Quad-Release Handles on page 64.	29
m	29
warning	29
DO NOT use WD-40®, 3-in-1 oil®, or other penetrating lubricants on quick-release axles or camber inserts. Otherwise, binding and/or damage to the wheelchair may occur.	29
5. Clean quick-release axles and camber inserts once a week with a Teflon® lubricant.	29
m	29
warning	29
DO NOT use your wheelchair unless it has the proper tire pressure (p.s.i.).	29
DO NOT overinflate the tires. Failure to follow these suggestions may cause the tire to explode and cause bodily harm. The recommended tire pressure is on the sidewall of the tire.	29
CAUTION	29
As with any vehicle, the wheels and tires should be checked periodically for cracks and wear, and should be replaced if damaged. Replace as recommended, refer to Replacing/Repairing Rear Wheel Tire/Tube on page 30 and Replacing/Repairing Caster Tire/...	29
6. Periodically adjust wheel locks in correlation to tire wear. Refer to Replacing/Adjusting the Wheel Locks on page 59.	30
i	30
Tire wear is excessive if:	30
• Pneumatic Tires - there is missing tread or the tires are bald.	30
• Urethane Tires - there are cuts, surface defects or the tires are loose on the rims.	30
• Rubber Tires - 30% or more of the tire has worn away.	30
Invacare recommends that rear wheel tire/tube and caster tire/tube be replaced every five years.	30
