HYDRAULIC SYSTEM 
E414 E415 E416 
CONTROL OF SINGLE-ACTING 
CYLINDER 
Single-acting hydraulic cylinder is always 
connected to quick coupling "1". 
Lifting  Lever in position "a" 
(pressure in quick 
coupling "1") 
End of lifting  Lever is shifted to 
position "b" – neutral 
Lowering  Lever is shifted to 
position “c“ – floating 
End of lowering Lever is shifted to 
position “b“ – neutral 
 
 
 
 
CONTROL OF DOUBLE-ACTING 
CYLINDER 
Double-acting hydraulic cylinder is 
connected to quick coupling "1" and "2". 
Movement in 
one direction 
Lever in position "a" 
(pressure in quick 
coupling "1") 
End of 
movement 
Lever in position "b"– 
neutral 
Movement in 
opposite 
direction 
Lever in position "d" -
(pressure in quick 
coupling "2") 
End of 
movement 
Lever in position "b"– 
neutral 
Lightened 
position 
Lever in position "c" 
(low pressure in 
quick coupling “2”)  
 
 
 
The outer circuit control lever 
must be moved as quickly as 
possible over position „c" (floating 
position) when working with 
double-acting cylinder, because 
both sides of cylinder are 
connected with the return line 
and it means that uncontrolled 
movement of the piston rod might 
occur.
