Periodically check that the fan mounting bolts in the fan hub have not loosened. If, for any
reason, it becomes necessary to remove the fan or re-tighten the fan mounting bolts, apply a
good grade of commercially available thread locking compound to the bolt threads and tighten
to the torque value shown in the TORQUE SETTING TABLE later in this section. Fan belt(s)
should be check regularly for wear and correct tensioning.
FUEL SYSTEM

tank(s), it is advisable to top up after the machine is shut down or at the end of each working
day. Drain any sediment or condensate that may have accumulated in the tank(s). Refer to
MAINTENANCE CHART.
