SEAT 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 Quantum Dynamo ATS was configured at your authorised Pride Dealer 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 Quantum Dynamo ATS 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 (3/4-in.) off the ground. This is the ideal setting for most Quantum Dynamo ATS 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 authorised Pride Dealer before attempting to change the anti-tip wheel height! Chang-
ing 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 authorised Pride Dealer make a
small adjustment to the pre-programmed deceleration setting in the controller or by moving the seat assembly
further to the rear of your power chair.
NOTE: Before making height adjustments on your anti-tips, consult your authorised Pride Dealer to make
sure that your seat is positioned properly. Moving your seat rearward 2.54 cm (1 in.) may be sufficient.
ANTI-TIP WHEEL ADJUSTMENT
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
suspension. Raising the anti-tip wheels stiffens the suspension while lowering the anti-tip wheels softens the suspension.
To adjust the anti-tips:
1. Make sure the power chair is not in freewheel mode.
2. 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 10.
3. Use a 1/2-in. spanner and 1/2-in. socket to remove the anti-tip wheel.
4. Use a 5/32-in. hex key and 7/16-in. socket to remove the anti-tip
adjustment bolt.
5. Raise or lower the anti-tip wheel in .6-cm (1/4-in.) increments.
6. Replace the hardware into the appropriate holes and tighten.
7. Install the anti-tip wheel.
