– The two articulated parts at the top of the glide arm are
now upright and closed.
– Pull the clamping lever (25) upwards until the clamping
wedge is positioned between the two articulated parts at
the bottom of the glide arm.
– This locks the glide arm (28), which is pushed all the way
back.
Glide arm pulled all the way forward:
– Pull the glide arm (28) all the way forward.
– The glide mechanism is now completely extended.
– Pull the clamping lever (25) upwards until the clamping
wedge is positioned between the two articulated parts at
the bottom of the glide arm.
– This locks the glide arm (28), which is pulled all the way
forward.
