COMFORT ADJUSTMENTS

The Synergy Seat is the standard seat assembly for your power chair. After you have become familiar with your power
chair’s operation, you may find the need to make adjustments to the seat to increase your comfort. Information on seat
adjustment is contained in separate manuals that accompany this product.
WARNING! If your power chair was configured at your Quantum Rehab Specialist or service
centre, please consult your healthcare professional before changing seat position or making any
other adjustment. Some of these adjustments may degrade your power chair’s performance and
safety by changing its centre of gravity.
ANTI-TIP WHEELS
The power chair’s mid-wheel drive design provides superior performance and safety. The anti-tip wheels are an integral
part of this design because they provide you with stability during deceleration. The anti-tip wheels are preset at the factory
to a height of 1.9 cm off the ground. This is the ideal setting for most power chair users. However, you may encounter
situations where you may need to adjust the anti-tip wheels. For instance, if you drive your power chair on surfaces such
as deep pile carpeting, you may notice that the anti-tip wheels have a tendency to drag on the carpet. In this case, you may
need to raise the anti-tip wheels. If you drive your power chair primarily on smooth surfaces such as linoleum or tile, you
may find that you tip forward more than is comfortable for you. (This may be more apparent for lighter users.) In this case,
you may need to lower the anti-tip wheels.
WARNING! Consult your Quantum Rehab Specialist before attempting to change the anti-tip wheel
height! Changing the anti-tip height affects handling under deceleration!
WARNING! The higher you raise the anti-tip wheels, the more you increase your power chair’s
tendency to tilt forward when coming to a stop. You can compensate for this by having your
Quantum Rehab Specialist make a small adjustment to the pre-programmed deceleration setting
in the controller or by moving the seat assembly farther to the rear of your power chair.
NOTE: Before making height adjustments on your anti-tips, consult your Quantum Rehab Special-
ist to make sure that your seat is positioned properly. Moving your seat rearward 2.54 cm may be
sufficient.
You can adjust the anti-tip wheels so that they are higher or lower.
Adjusting the anti-tip wheels also affects the stiffness of the suspen-
sion. Raising the anti-tip wheels stiffens the suspension while lowering
the anti-tip wheels softens the suspension.
To adjust the anti-tips:
WARNING! Make certain that your power chair is
powered off and is not in freewheel mode.
1. Use a hex key and a socket to loosen the nut and bolt that fasten
the anti-tip spring to the anti-tip arm. See figure 22.
2. Use a spanner and socket to remove the anti-tip wheel.
3. Use a hex key and socket to remove the anti-tip adjustment bolt.
4. Raise or lower the anti-tip wheel in .6-cm increments.
5. Replace the hardware into the appropriate holes and tighten.
6. Install the anti-tip wheel.
7. Tighten the nut and bolt that fasten the anti-tip spring to the anti-tip
arm.
