Power units and pumps
Only WEBER-HYDRAULIK power units and hand pumps may be used to drive the spreader.
Equipment from other manufacturers can only be used under certain conditions.
Therefore always consult with us before operating a device with a power unit from another
manufacturer!
ATTENTION!
Before using pumps and power units from other manufacturers always
contact WEBER-HYDRAULIK or an authorised dealer.
Incorrect application can lead to hazardous situations for which we cannot
accept any liability!
Hoses
The connection of the device with the power unit is carried out via high pressure hoses.
Hoses are available in lengths of 5 m, 10 m, 15 m and 20 m. As the length of the lines
increases so too does the associated pressure loss. With a line length of 50 metres this
pressure loss remains acceptable and has no significant effect.
CAUTION!
Do not use damaged hoses!
With damaged hoses there is a danger of escaping hydraulic medium under
pressure, or of the hoses whipping around.
Therefore:
» The hoses should be subjected to a visual inspection (leak-
tightness, surface damage such as kinks) after every use and
at least once per year
