B. CRITICAL MAINTENANCE TIPS
1. Torque settings:
A torque setting is the optimum tightening which should be made on a particular fastener. It is
important to use proper torque settings where specifi ed. When not specifi ed, torque settings should
be: M5 fasteners = 5 Nm [44in-lbs], M6 fasteners = 7 Nm [62 in-lbs], M8 fasteners = 10 Nm
[88 in-lbs]. For all others torque setting should be 6.8 Nm [60 in-lbs]. All joints secured with threaded
fasteners will relax over time resulting in an actual torque that is lower than the initial torque setting.
This is especially applicable for joints with elastic components.
