Special Requirements for Adjustments to the Scissor Wheel Locks

Depending on the adjustment, it may be necessary to rotate or replace the support for the wheel lock. This makes

further wheel lock adjustments possible.

7.5.3 Adjusting the braking force of the drum brake

INFORMATION

After making adjustments, check that activating the manual brake lever creates a sufficient braking effect.

Note that the drum brake must still be able to produce sufficient braking force even when the manual brake lever

is locked into a ratchet position.

To achieve an optimum braking effect, the braking force is adjusted using the adjustment screw (see fig. 27, item

2).

Increase the braking force: Back off the adjusting screw.

•

Reduce the braking force: Screw in the adjustment screw.

1) Loosen the counter nut (see fig. 27, item 1) and back off the adjustment screw until a scraping noise can be

heard when the rear wheel is rotated.

2) Screw in the adjustment screw (see fig. 27, item 2) until the scraping noise at the rear wheel disappears and

the wheel runs freely.

3) Tighten the counter nut (see fig. 27, item 1) until the adjustment screw is fixed.

→ The braking force of both rear wheels must be adjusted equally.

The height of the back tube is adjustable. Adjustment can be made within the hole matrix at intervals of 25 mm over

a range of 100 mm.

1) Preparation:

→ Remove the drive wheels and secure the wheelchair by jacking it up.

→ Remove any add-on components attached to the back tubes that are in the way (for instance the side panel

mounts, see fig. 28).
