Device Protection

Please be sure to heed the following information or instructions to prevent
the splitter from being damaged!
Before all splitting work, check whether the pressure surfaces of the split-
ting wedge and the pressure pieces are sufficiently lubricated! Lubricate
the pressure surfaces at the latest after 3 to 5 splittings! Solely use the
Darda special lubricant paste!
Avoid frequent full capacity utilization of the splitter by using multiple
splitters with the smallest possible borehole intervals! Constantly reach-
ing the maximum pressure and retraction of the splitting wedge in unsuc-
cessful splitting leads - particularly with insufficient lubrication - to pre-
mature wear in the splitting heads and in some cases to the breaking of
the wedge head!
During and after each splitting process, check whether the splitting wedge
correctly executes the desired movement after pressing the operating
lever!
If the splitter is still operated after the wedge head breaks, this usually
leads to the destruction of the splitter due to the uncontrolled meeting of
the piston rod and wedge!
Check the splitter for operational safety before any start-up!
Do not increase the pressure in the hydraulic circuit under any circum-
stances! The pressure limitation valve on the hydraulic aggregate must
limit the hydraulic pressure to a maximum of 50 MPa!
Exclusively use hydraulic oils approved by the manufacturer!
Never mix oils with different viscosities or from different manufacturers! If
in doubt, completely change the hydraulic oil!
Make sure that no foreign bodies (such as stones, sand, water) enter the
hydraulic circuit when the hydraulic hoses and couplings are dismantled!
Immediately cut off the hydraulic supply in case of a malfunction of the
splitter, secure it against accidental start-up and inform the superior in
charge about the malfunction!
Make sure (due to the danger of the hydraulic oil overheating) that the op-
erating lever is in the zero position on at least one splitter in the case of
long interruptions with a running hydraulic aggregate!
For the protection of the device, however, we recommend that you switch
off the hydraulic aggregate.
Remove the salt deposits after use under water by dipping and brushing
off the splitter in / with freshwater!
