of the TTPM3 should carry out the adjustments.

4.4.2 Torque settings, and thread locking
Do not over-tighten the screws. The max torque for the different screw sizes are as
follows: M2 = 0,13 Nm, M2.5 = 0,26 Nm, M3 = 0,46 Nm, and M4 = 1.1 Nm.
Threadlock like Locktite 243 should be used on screws that hold plastic parts, for instance
the screws for the micro-switches.
