in two steps;
• Tighten the 18 attachment screws
crosswise to 100 Nm.
• Tighten the screws crosswise to 300

Tip
Use a torque converter between the screw
and the torque wrench, to facilitate the
tightening of the screws.

Note
Use caution when attaching the screws that
secure the gearbox.
If a screw is dropped, it will probably end
up in the recess underneath the gearbox
and be very difficult to reach. Using a
magnet will probably be the only way to get
hold of the lost screw.

• Person one: working under the base,
holding the torque wrench in place,
making sure the bit is correctly fitted.
• Person two: working beside the ro-
bot, working with the torque wrench.
