If worn or defective components (high pressure hoses etc.) are not immediately replaced,
WAITZINGER
will
not accept product liability. Conveying pipes are not under stress when the distributor boom is stowed, and
can thus be replaced without problems at that time. If conveying pipes are replaced when the distributor boom
is deployed, stresses may be introduced during assembly.
墌
To ensure a long working life for the conveying pipes, after delivering approx. 6,000 m
3
, rotate all conveying
pipes 120
°
clockwise, and rotate the elbows 180
°
. Check the minimum wall thicknesses and operating pressure.
WARNING:
If you use compressed air for cleaning the conveying pipes, this is at your
own risk! WAITZINGER accepts no liability for the risks involved. If never-
theless you do use compressed air for cleaning, information can be found in
an additional sheet which can be requested from WAITZINGER as required.
