9.2 Wear parts and screw connections
9.2.1 Checking wear-prone parts
Wear-prone parts are: spreader vanes, agitator head, outlet, hydraulic hoses
and all plastic parts.
Plastic parts are subject to a certain ageing process even under normal spread-
ing conditions. Plastic parts are e.g. protective grid locks, connecting rod.
Inspect wear parts regularly.
Replace these parts if they show signs of wear, deformation, holes or ageing.
Otherwise, the spreading pattern will not be correct.
The durability of wear parts depends, among other things, on the material being
spread.
9.2.2 Checking the bolted joints
Bolted joints have been tightened to the specified torque and locked at the facto-
ry. Vibrations and shocks, in particular during the initial operating hours, can loos-
en bolted joints.
With new machines, all screw connections are to be checked for their tight
seat after approx. 30 operating hours.
Check all the bolted joints regularly for tightness, and definitely before the
start of the spreading season.
Some components (e.g. spreader vanes) are mounted with self-locking nuts.
When mounting these components always use new self-locking nuts.
