Otto Bock 476L52 Series Instructions For Use Manual page 30

INFORMATION
The clamping levers can be replaced by the provided screws to make it dif­
ficult for unauthorised persons to make adjustments (see Page 26).
The head support position is adjusted via the clamping levers on the clamp
fitting, the rotation joint at the upper end of the vertical tube (with
476L52=SK015/25) and the joints (with 476L52=SK035).
6.2.1.1 Clamp fitting: height and horizontal angle
The head support height and horizontal angle are adjusted via the clamping
lever on the clamp fitting. With the 476L52=SK015, the depth of the head
support can be adjusted here as well.
1) Release the clamping lever (see fig. 14, item 2).
2) Loosen the Allen head screw on the clamp plate (see fig. 14, item 1).
3) Slide the vertical tube to the desired height and turn it to the desired
horizontal angle.
INFORMATION: With the 476L52=SK015 mounting kit, the depth of
the head support can also be adjusted by turning the offset vertic­
al tube (see fig. 17, item 2). This requires readjustment of the rota­
tion joint (see Page 30).
4) Tighten the clamping lever.
5) Slide the clamp plate on the vertical tube onto the clamp fitting from
above. Tighten the Allen head screw.
6.2.1.2 Rotation joint (476L52=SK015/25): depth and angle
The head support depth and angle are adjusted via the clamping lever on the
rotation joint.
1) Release the clamping lever (see fig. 17, item 1).
2) Slide the horizontal tube to the desired depth (see fig. 17, item 4). Main­
tain an overhang of 50 mm.
3) Turn the rotation joint to the desired vertical and horizontal angle (see
fig. 17, item 3).
4) Tighten the clamping lever.
6.2.1.3 Joints (476L52=SK035): depth and vertical angle
The head support depth and vertical angle are adjusted via the clamping
levers on the joints.
1) Release one or both clamping levers as needed (see fig. 18, item 1).
2) Slide the head support to the desired position.
3) Tighten the clamping levers.
