Operating Instructions LAA Hand pump ZPH 3 /. - . 84072/6680-85 GB Issue 7.
1 Basic operation and designated use of the machine 1.1 The machine has been built in accordance with state-of-the-art standards and the recognized safety rules. Nevertheless, its use may constitute a risk to life and limb of the user or of third parties, or cause damage to the machine and to other material property. 1.
.2 Before starting up or setting the machine in motion and during operation of the machine make sure that nobody is at risk. 3.3 Before transporting the machine always check that the accessories have been safely stowed away. 3.4 Make sure that there is enough lighting during work. 3.5 Avoid any operation that might be a risk to machine stability. 3.6 Check the machine at least after every operation for obvious damage and defects. Report any changes (incl.
5 Safety Instructions for Hydraulic hoses All instructions as to safe use of hydraulic hoses can be found in the booklet HR 1495 35 219 deliverd with the hoses. 6 Intended use The hand pump ZPH 3/... serves mainly for operation of LUKAS double-acting cylinders. Jt must be used only in connection with components out of the LUKAS Rerailing System or the Hydraulik Tools System 50 MPa, resp. 70 MPa.
8.3 Venting the cylinder Connect the cylinder with the pump. Extend the piston by half its stroke and turn the cylinder so that the piston is facing downwards. The highest point of the cylinder must be on a lower level than the pump. Fully extend the piston and retract again so that eventual air bubbles can escape into the oil container of the pump. Remark: The oil filler cap of the pump must be open during bleeding.
12.2 Special function „quick stop“ If you open the drain valve rapidly (rotation to the left), an existent quickstop only for 50 MPa cylinders StMu61-M (silver) is activated, i.e. a non-return valve, incorporated in the quick-connect coupling, will prevent the oil from flowing back. While the hose is at zero pressure, the cylinder remains under pressure. Pump and cylinder can now be separated and the pump can be used elsewhere.
14 Trouble shooting Problem Possible Cause Solution Cylinder does not Oil level in pump reservoir is low. Add oil according to the Maintenance instructions on 12.1 advance, advances slowy, Drain valve open Drain valve closed or advances in spurts. Loose hydraulic coupler Check that all couplers are fully tightened Load is too heavy Do not attempt to lift more than rated tonnage Air trapped in system Remove air according to the instructions on page 8.
