NOTE: Before adjusting or replacing the high/undermount wheel locks, ensure that the tires are inflated to the recommended psi on the sidewall of the tire. Replacing the Wheel Lock 1. Remove the hex screws and remove the existing wheel lock from the wheelchair. 2. Install the new wheel lock and secure with the existing hardware. Adjusting the Wheel Lock 1. Engage the wheel locks. NOTE: Any wheel lock adjustment should embed the wheel lock shoe at least 3/16-inch into the pneumatic tire (1/8-inch for urethane wheels) when engaged. 2. If necessary, loosen the hex screw(s) that secure the wheel locks to the wheelchair frame and adjust position of the wheel lock until the 3/16-inch (1/8-inch for urethane wheels) measurement is obtained for correct wheel lock adjustment. 3. Securely tighten the hex screw(s). 4. Engage the wheel locks and push against the wheelchair and determine if the wheel locks engage the wheel locks enough to hold the wheelchair. 5.

NOTE: When changes to the left hand column occur, follow across the chart and refer to the X procedure to maintain the proper stability, safety and handling of the wheelchair.	12
To maintain maximum stability, position the rear wheels in the most rearward position in the axle mounting plate. Moving the rear wheels to any of the other mounting positions causes the wheelchair to decrease in stability.	12
Always ensure stability before moving the rear wheels forward. Test wheelchair before it is occupied by the enduser to ensure safety.	12
Repair and Service Information	13
Unless otherwise noted, all service and adjustments should be performed while the wheelchair is unoccupied.	13
Operating Information	13
To determine and establish your particular safety limits, practice bending, reaching and transferring activities in several combinations in the presence of a qualified health professional before attempting active use of the wheelchair.	13
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.	13
Mounting the front casters on the inside of the wheelchair frame will reduce the stability of the wheelchair. Try various front caster positions to find the safest front caster position for your needs.	13
DO NOT operate on roads, streets or highways.	13
DO NOT climb, go up or down ramps or traverse slopes greater than 9.	13
DO NOT attempt to move up or down an incline with a water, ice or oil film.	13
DO NOT attempt to ride over curbs or obstacles. Doing so may cause your wheelchair to turn over and cause bodily harm or damage to the wheelchair.	13
DO NOT stand on the frame of the wheelchair.	13
DO NOT attempt to reach objects if you have to move forward in your seat.	13
DO NOT attempt to reach objects if you have to pick them up from the floor by reaching down between your knees.	13
DO NOT lean over the top of the back upholstery to reach objects from behind as this may cause the wheelchair and/or seating system (if any) to tip over.	13
DO NOT shift your weight or sitting position toward the direction you are reaching as the wheelchair and/or seating system (if any) may tip over.	13
DO NOT tip the wheelchair without assistance.	13
DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur.	13
DO NOT use footplates as a platform. When getting in or out of the wheelchair, make sure that the footplates are in the upward position or swing footrests towards the outside of the chair.	13
Make sure the back is locked securely BEFORE using the wheelchair - otherwise injury can occur.	13
ALWAYS engage both wheel locks and reduce the gap distance BEFORE transferring to and from the wheelchair. Turn all casters parallel to the object you are transferring onto.	13
Do not sit or transfer into the wheelchair unless it is fully open and the seat rails are fully seated into the seat clamps.	14
Wheel locks are NOT brakes. DO NOT attempt to stop a moving wheelchair with the wheel locks.	14
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.	14
NEVER try to lift or tip the wheelchair by cantilever arms or T-arms, serious injury can occur.	14
DO NOT overtighten hardware attaching to the frame. This could cause damage to the frame tubing.	14
always keep hands and fingers clear of moving parts to avoid injury.	14

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.	14
Tire Pressure	15
DO NOT use your wheelchair unless it has the proper tire pressure (p.s.i.). DO NOT overinflate the tires. Failure to follow thes...	15
Replacement of a tire or tube must be performed by a qualified technician.	15
Make sure the detent pin and locking pins of the quick/quad-release axle are fully released before operating the wheelchair.	15
The locking pins must be protruding past the inside of the rear wheel axle bushing for a positive lock.	15

Virtually all activities which involve movement in the wheelchair have an effect on the center of gravity. Invacare recommends using seat/chest positioning straps for additional safety while involved in activities that shift your weight.	17
To assure stability and proper operation of your wheelchair, you must at all times maintain proper balance. Your wheelchair has ...	17
Coping with Everyday Obstacles	17
Coping with the irritation of everyday obstacles can be somewhat alleviated by learning how to manage your wheelchair. Keep in mind your center of gravity to maintain stability and balance.	17
A Note to Wheelchair Assistants	17
When assistance to the wheelchair user is required, remember to use good body mechanics. Keep your back straight and bend your knees whenever tilting wheelchair or traversing curbs or other impediments.	17
m warning	17
Do not attempt to lift or tilt a wheelchair by using any removable (detatchable)parts. Lifting by means of any removable (detatchable)parts of a wheelchair may result in injury to the user or damage to the wheelchair.	17
Also, be aware of detachable parts such as arms or legrests. 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).	17
When learning a new assistance technique, have an experienced assistant help you before attempting it alone.	17

After mastering the techniques of tipping the wheelchair, use this procedure to tackle curbs, short stairs, etc.	18
Method 1 - Wheelchair with Step Tubes	18
NOTE: For this procedure, refer to FIGURE 2.1.	18
Apply a continuous downward motion until the balance point is achieved and the front casters clear the curb. At this point, the assistant will feel a difference in the weight distribution.	18
Roll the wheelchair forward and slowly lower the wheelchair in one continuous movement onto the sidewalk.	18
m warning	18
DO NOT let the wheelchair drop the last few inches to the ground. This could result in injury to the occupant.	18
Push the wheelchair forward until the rear wheels roll up and over the curb.	18

Follow this procedure for moving the wheelchair between floors when an elevator is NOT available:	19
1. If so equipped, rotate the anti-tippers so the wheels are facing up.	19
2. After the wheelchair has been tilted back to the balance point, one assistant (in the rear) backs the wheelchair up against the first step, while securely grasping a non- removable (non-detachable) part of the wheelchair for leverage.	19
3. The second assistant, with a firm hold on a non-detachable part of the framework, lifts the wheelchair up and over the stair and steadies the wheelchair as the first assistant places one (1) foot on the next stair and repeats STEP 1.	20
4. The wheelchair should not be lowered until the last stair has been negotiated and the wheelchair has been rolled away from the stairway.	20
5. If so equipped, rotate the anti-tippers so the wheels are facing down.	20
