Preparing your wheelchair for use

Never attempt to adjust the seat angle with the user still occupying the chair. Never attempt to drive the wheelchair with set angle in excess of 15° from horizontal.

Removal of seat frame

To remove the seat frame press down the finger bar and pull backwards to release the seat stem and lift the seat upwards until it can be raised no further. With the tip of the seat stem resting in it’s receiving hole, pull the whole seat gently towards you (lifting at the same time) until the seat is clear of the powerbase.

Seat pan height adjustment

In addition to being able to adjust the single angle of the seat pan to the power base by selection of the appropriate hole in the seat stem, the height of the complete seat pan can be adjusted to suit the chair user (Fig. 8). The chair will normally be supplied with the seat pan at its lowest setting. To raise the rear of the seat pan, remove two nuts and bolts at either end of the seat location bar. The seat location bar may now be raised to the desired level and bolts reinserted.

Having raised the seat location bar, it will be necessary to select a higher position with the seat stem.

Armrests/skirt guard

To fit the armrest/skirt guard assembly, ensure that locking pin (A) (Fig. 9) is in the ‘unlocked’ position shown. Lower the armrest into the support cups and press down to ensure a firm location. Release the locking pin lever to lock position. To adjust the height of the armrest pull back the lever of locking pin (B) and hold. Lift or lower armrest to the required position and release pin to lock position, check armrest has seated properly.
