Rail mounting hardware
Installing the rail mounting
1. Assemble the base and the two angles using four socket head cap screws
(M8 x 40 mm), washers for M10, spring washers for M8 and M8 nuts
(
Figure 6 on page 6 ).
Fit the four socket head cap screws (M8 x 40 mm) and washers for M10 to the side of
the angle so that the holes in the angles are covered.
2. Loosely bolt the mounting rail and a clamping plate to the top railing using four screws
(M8 x 120 mm) with washers for M8, spring washers for M8 and M8 nuts
(
Figure 7 on page 7 ). Do not tighten the screws until the entire rail mounting is aligned
and adjusted for height.
3. Loosely bolt the mounting rail and the second clamping plate to the bottom railing
using four screws (M8 x 120 mm) with washers for M8, spring washers for M8 and M8
nuts (
Figure 7 on page 7 ).
• To change the installation height of the mounting rail, slide the screws along the
slots or use other slots.
• To change the mounting height of the base, fit the base higher or lower.
• For railings that are not vertically positioned or have different diameters, align the
mounting rail vertically by fitting shims between the railings and the mounting rail.
4. Fit a clamp to the middle and end of the supporting pipe using one M8 x 40 mm screw
and spring washer for each clamp ( Figure 8 on page 7 ).
5. Bolt the fastening lug to the clamp on the end of the supporting pipe using four
M8 x 40 mm socket head cap screws, washers, spring washers and nuts
(
Figure 9 on page 8 ).
6. Insert the supporting pipe through the base and fit the third clamp between the angles
using one M8 x 40 mm socket head cap screw and spring washer
(
Figure 10 on page 8 ).
• Set the supporting pipe axial offset using the distance from the clamp between the
angles and the clamp in front of the base (see
Figure 3 on page 3 and section
Placing the probe in the service position on page 12 ).
• Lock the supporting pipe to avoid twisting using the clamp between the angles.
Secure the probe on the vertical axis.
Important note: Fit the pipe cap on the end of the supporting pipe facing the user to
prevent leg injuries due the sharp pipe edges. The pipe can be shortened as needed
before fitting the pipe cap.
7. Bolt the retaining strap for the spring locking pin to one of the angles using an M5
socket head cap screw. Secure the supporting pipe against axial movement by
inserting the spring locking pin into a hole (
Figure 11 on page 9 ).
8. Loosely bolt one of the three threaded brackets to one of the unthreaded brackets
using one M5 x 20 mm socket head cap screw and a spring washer. Push the bracket
onto the mounting pipe; pay attention to the bottom installation dimension (
Figure 12
on page 10 ). Tighten the screws.
