6.2.7 Adjustments in the case of a wheelbase extension

The manufacturer offers a wheelbase extension for this product. This allows the use of the wheelchair with an

adaptable handbike (wheelchair with double axle: see fig. 20) or a particularly passive setting for the wheelchair

(see fig. 21, item 1). Depending on the order, the wheelbase extension may already be installed when delivered.

All adjustments with the wheelbase extension installed are made in the same way as the adjustments without

wheelbase extension:

•

Adjusting the horizontal position of the drive wheel: see Page 9

•

Adjusting the drive wheel height: see Page 10

Special requirement: During adjustment of the drive wheel height, 4 Allen head screws must be loosened and

moved on each slider (see fig. 22, item 1).

•

Adjusting the track width: see Page 12

Special requirement: During adjustment of the track width with camber module 0°/3°, the clamps for the

wheelbase extension must be loosened (see fig. 22, item 2). Adjusting the track width with camber module

6°/9° is done by adjusting the fitting (see fig. 16).

•

Adjusting the drive wheel camber: see Page 11

Special requirement: During exchange of the camber modules, the clamps for the wheelbase extension must

be loosened (see fig. 22, item 2).

INFORMATION: For a wheelbase extension with a double axle, only certain camber modules can be

combined:

–

Front axle camber modules/drive axle camber modules: 0°/3°, 3°/6° or 6°/9°.

•

Adjusting the knee lever wheel lock: see Page 19

Special requirement: For extreme settings, the wheelbase extension must be used in combination with an

"upgrade" knee lever wheel lock (see fig. 21, item 2).

If necessary, the wheel lock holder must be moved behind the locking mechanism for the side panel supports.

CAUTION: Risk of falling, tipping over. If the wheelbase extension is used in combination with a

double axle, there is no braking function available when the drive wheels are moved to the drive axle

(e.g. for adaptation to a handbike). Inform the user.
