1. Tightening Bolts & Nuts
Check all loader bolts and nuts for ghtness every 50 working hours. The movement of the loader
over rough terrain may cause bolts to come under pressure and over a long period of me some
slight stretching of the bolt may occur. The slack created may need to be taken up by ghtening.
Please refer below for recommended torque se ngs.
