slot on the auxiliary bracket.
2. Slide the mounting brackets onto the angle steel horizontally and insert the square-neck
bolt into the slot.

Use a 16 mm (0.67 in.) M10 torque wrench to tighten the nuts to 40 N·m (354.03 lbf·in.) so that
the mounting brackets are secured onto the angle steel, as shown in
Figure 7-32 .
NOTICE
Tighten the nuts on the two square-neck bolts synchronously. After the main and auxiliary
brackets are secured properly, measure the spacing between the brackets on both sides and ensure
that the spacing is the same on the two sides.
