4.6.2. Back sag
A well-fitted back allows you to sit more relaxed in the long term and
reduces the risk of pressure points. Make sure that there is enough sag
in the pelvic area!
• First, completely remove the upholstery of the backrest covering
23
(Fig. 23).
• Loosen the Velcro Fasteners of the tensioning straps (Fig 24).
• Adjust the tapes in order, starting from the bottom.
• Put the upholstery back over the tensioning straps.
4.7. Brakes
The wheelchair is equipped as standard with parking brakes for ope-
ration by equipped for the wheelchair user. Optionally, you can extend
24
the equipment with a drum brake, which is used by an attendant.
To adjust the brake, contact your specialist dealer.
Remember that incorrectly adjusted brakes can have
life-threatening consequences.

Your specialist dealer can adjust the drum brake
using the installation instructions.
The parking brake must not be used as a service
brake, as there is a risk of fatal injury due to the risk
of falling!

Be aware of the risk of burns if your hands heat up
when braking over the push rims!
4.7.1. Actuation of the locking brake
The parking brake may only be used for parking. Only the hand rims on
the drive wheels (Fig. 25) or the optional drum brakes for escorts are
used to brake the drive.
• When braking, grasp the highest point of the handrims. First let the
handrims slide between your hands.
• Slowly apply the braking force via the holding force that you apply
to the gripping.
• To increase the braking force, slowly increase the holding force on
the handrims until the wheelchair stops.
• As soon as the wheelchair is stationary, push both brake levers
forward (Fig. 26). The wheelchair is safely braked when it can no
longer be pushed away and both brake levers are pushed forward
as far as they will go.
• Pull the lever back towards you to release the brake.
4.7.2. Operation with brake lever
extension (optional)
You can optionally equip your wheelchair with a brake lever extension.
The extended lever reduces the necessary effort and is therefore parti-
cularly recommended for people with reduced arm and hand strength.
• Bring the wheelchair to a standstill (see chapter 4.7.1).
• Push both brake levers forward. The wheelchair is safely braked
when it can no longer be pushed away and both brake levers are
pushed forward as far as they will go (fig. 26/27).
