Adjusting The Track; Adjustments In The Case Of A Wheelbase Extension - Otto Bock Ventus Instructions For Use Manual

6.2.5 Adjusting the Track

INFORMATION
► The track must be adjusted after the following adjustments have been made:
→ Adjusting the track width: see Page 12
→ Adjusting the rear wheel camber: see Page 13
► The track setting must be checked and, if necessary, adjusted after the following adjustments have been
made:
→ Adjusting the horizontal position of the rear wheel: see Page 10
→ Adjusting the height of the rear wheel: see Page 11
INFORMATION
► Always make the track adjustment on both sides and check both sides.
► With each track adjustment, always check the symmetry of the track width setting. To do this, measure the
distance between the outer side of the camber module and the outer side of the clamping flange on both
sides (see fig. 11).
► The caster journal angle should be checked immediately after every adjustment to the track (see Page 17 ff.).
> The clamping screws on the clamping flanges must be loosened until the camber modules and the rear wheel
axle are only slightly clamped (see Page 12).
1) Place the wheelchair on an even surface. Avoid twisting the axle when doing this.
2) Pull the rear wheel out slightly in order to make room for the installation.
3) Place the spirit level on the camber module (see fig. 17).
4) Carefully twist the camber module until the spirit level is centred (not pictured).
If necessary ‒ after changing the wheel camber, for example ‒ twist the rear wheel axle carefully as well until
the spirit level is centred (see fig. 18).
5) Tighten the clamping screws on the clamping flanges to 10 Nm (see fig. 9, item 1).

6.2.6 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. 19) or a particularly passive setting for the wheelchair
(see fig. 20, 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 rear wheel: see Page 10
• Adjusting the rear wheel height: see Page 11
Special requirement: During adjustment of the rear wheel height, 4 Allen head screws must be loosened and
moved on each slider (see fig. 21, 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. 21, item 2). Adjusting the track width with camber module
6°/9° is done by adjusting the fitting (see fig. 12).
