6. Start-up
•
At start-up, fill reservoir of the hydraulic assembly with 24 litters of hydraulic oil.
•
Adjust pressure switch according to the lubrication system application / design requirements.
Dual-line systems with ZV – distributors: 320 bar (standard).
Progressive systems with ZP-A and E4 distributors 160 bar. ZP-B distributors: 320 bar.
Single-line systems with ZE-C distributors: 160 bar.
Adjustment of the pressure switch is performed as follows:
•
Remove protective cap and loosen lock nut.
•
Loosen adjusting screw by turning it counter-clockwise until you cannot feel the spring tension.
•
Close lubricant outlet and activate electric motor.
•
While operating pump, turn adjusting screw clockwise until the desired pressure is indicated on the
system pressure gauge.
Maintenance of the hydraulic motor
•
For ease of handling, remove all hoses from pump before starting.
•
Clamp hydraulic motor housing in a vice and carefully move hydraulic piston to topmost position.
•
Unscrew cap from cylinder. Affix vice grips to piston rod and pull upward.
•
Unscrew cap from rod. Loosen the screws that connect the cylinder with the housing.
•
Carefully remove cylinder, taking care not to tilt it, so as to prevent bore from being damaged.
•
Push bow in lowest position, but do not put your fingers into the mechanism.
•
Remove locking wires from external valves, remove upper lock nut and unscrew valve stem.
Remove rubber valve.
•
Carefully check all disassembled parts for damage.
•
Push rollers downward and inward using vice grip, pliers or suitable object to lift them out of grooves.
•
Check spring clip and valve traverse (movement) while in installed position.
•
Remove the entire piston rod valve mechanism from bow and traverse.
•
Loosen clamps from cylinder if they are to be replaced.
•
Clean all parts in solvent and dry carefully.
•
Check all parts for damage and wear and replace if necessary.
