Adjustments; Prerequisites - Otto Bock discovery tmax Instructions For Use Manual

CAUTION
Incorrect air pressure
Risk of falling, uncontrolled driving characteristics, tyre rupture
► Maintain sufficient air pressure. Do not exceed the maximum specifications when filling the tyres (see the
chapter "Technical Data").
► Do not use the wheelchair with over/under-inflated or unequally inflated tyres.
► Note that a single tyre with low air pressure can lead to uncontrolled driving characteristics.
► Note that low rear tyre pressure can reduce the braking force of the knee lever wheel lock.
INFORMATION
In general, only metric screws are used on the product.
Exception: axle mounting of the 12" rear wheels (1/2" hexagon head screw + hexagon nut)
INFORMATION
With the combination of Allen head screw/hexagon nut, a higher torque can be transmitted using the hexagon nut
than the Allen head screw.
Please note that the Allen head screw is only intended to be held in place so it does not turn when tighten­
ing/loosening the hexagon nut.
1) For plug-on rear wheels: slide the rear wheels onto the wheel attachments of the wheel adapters. The quick-
release axles must not be removable after releasing the pushbutton.
2) Slide the footrests into the holders on the front frame tube.
3) Fold the footplates down. If necessary, insert the calf band and adjust it.
4) Prior to the adaptation of the seating shell/seating system, further wheelchair settings must be adjusted as
required (see Page 9 et. seq.).
