frayed, abraded or leaking.
Never move the pump by pulling the

hoses.
Do not work with hoses sharply bent or

kinked.
Do not handle hoses that are

HYDRAULIC CONNECTIONS
No control valve fitted.
Pump (P) and tank (T)
connections for single and
double acting cylinders
controlled by remote mounted
valves.
2 way valve for operating single
acting cylinders and tools
requiring advance and retract
but no "hold" function. For
example crimpers and cutters.
3 way valve for operating single
acting cylinders requiring
advance, retract and central
load hold position. For example
simple lifting operations
4 way valve for operating double
acting cylinders requiring
advance, retract and central
load hold position. For example
lifting and positioning requiring
more control.
