1. Tightening Bolts & Nuts
Check all loader bolts and nuts for tightness 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 time some
slight stretching of the bolt may occur. The slack created may need to be taken up by tightening.
Please refer below for recommended torque settings.

DO NOT use these values if a different torque value or tightening procedure is given for a
specific application. Torque values listed are for general use only and include a +/- 10%
variance. Check tightness of fasteners periodically. DO NOT use air powered wrenches.
Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with
identical grade.
