The M4 threaded pins must then be loosened
again by several turns and the M6 tensioning
screws tightened again with a tightening torque
of 7 Nm and secured with screw locking fluid.
The threaded pins are then screwed in again
gently, making contact with the clamp. The
protruding pieces of tube can be shortened
using a metal saw and the tubes blocked with
the stoppers provided.

Assembly work on the wheelchair

For adapting to the wheelchair, one of the two
clamp cover stoppers (Fig. 53) supplied must
be mounted on the left as well as the right
frame tube.
In the first step, clamp the front adapter tempo-
rarily on the two frame tubes of the wheelchair.
To achieve this, the frame clamps are first
opened fully (turn clamp lever anti-clockwise).
Then the frame clamps must be attached to
the frame tube. By turning the clamp levers
clockwise, the frame clamps are then fixed
gently to the frame tube.
Now the correct fixing height must be achieved
by moving the adapter on the frame tubes. The
fixing height of the adapter on the wheelchair's
frame tubes is determined by the measure-
ments from the floor to the hook on the inser-
tion shaft on the steering head. This dimension
depends on the wheel size of the product to be
adapted. The guide values are shown below:

When the adapter sits temporarily in the rele-
vant position on the wheelchair's frame tubes,
the positions of the clamp cover stoppers can
be marked on the back of the wheelchair's
frame tube.
