5. ctions in this document for Typical Applications and Load Capacities Pump Safety 1 DO NOT EXCEED THE MAXIMUM CAPACITY OF THE PUMP OR TAMPER WITH THE INTERNAL HIGH PRESSURE RELIEF VALVE Creating pressure beyond the rated capacity can result in personal injury 2 Completely retract the ram before opening the filler screw on the pump to add hydraulic fluid An overfill can Cause personal injury due to excess reservoir pressure created when rams are retracted Ram Safety 1 DO NOT EXCEED THE MAXIMUM CAPACITY OF THE RAM Creating pressure beyond the rated capacity can result in personal injury 2 DO NOT SET POORLY BALANCED OR OFF CENTER LOADS ON THE RAM The load may tip and cause personal injury Operating Instructions Setup The pump may be operated in a horizontal position or in a vertical position with the head pointing down as shown 1 Assemble the hose between the pump and ram 2 Determine the appropriate attachment for your application assemble the attachment to the ram piston Bleeding Air From the System Air can accumulate in the hydraulic system during the initial setup or after prolonged use causing the ram to respond slowly or in an unstable manner To remove the air Zinko Hydraulic Jack Models ZPK 20 Operating Instructions continued 1 Place the ram at a lower level than the pump with the piston end pointing down 2 Extend and retract the ram several times without putting a load on the system Air will be release
6. d into the pump reservoir 3 With the ram fully retracted the pump sitting level and no pressure in the hydraulic system remove the pump s filler screw Fill the reservoir with approved hydraulic fluid until the fluid level is within 1 2 from the top of the reservoir IMPORTANT The use of extension tubes or off center attachments greatly reduces the capacity of the hydraulic system When using extension tubes put the shortest tubes on the end Some components in this set do not match the maximum pressure rating of the pump and ram USE A PRESSURE GAUGE IN THE SYSTEM TO MONITOR HYDRAULIC PRESSURE Operation 1 Turn the pump s release valve clockwise to a closed position IMPORTANT HAND TIGHTEN THE VALVE ONLY 2 Work the pump handle up and down to send oil through the hose to the ram causing the piston to extend to the work piece 3 Monitor the pressure gauge while completing the application NOTE The pump is equipped with an overload valve that will bypass oil back into the pump reservoir in an overload situation when the system meets maximum pressure In this case continued pumping will have no effect on the system If an overload system commonly occurs a higher capacity set is needed 4 To release pressure slowly turn the release valve counterclockwise the release speed is controlled by how fast the valve is opened Zinko Hydraulic Jack Models ZPK 20 To prevent personal injury release pump pressure and disconnect
7. pump tighten all hose connections using the correct tools DO NOT OVER TIGHTEN Connections need only be secure and leak free Over tightening can cause premature thread failure or high pressure fittings to split at pressures lower than their rated capacities 2 Should a hydraulic hose ever rupture burst or need to be disconnected immediately shut the pump off and open the control valve to release all pressure NEVER GRASP A LEAKING PRESSURIZED HOSE WITH YOUR HANDS The force of escaping hydraulic fluid could cause serious injury 3 DO NOT subject the hose to any potential hazard such as fire extreme cold or heat sharp surfaces or heavy impact DO NOT allow the hose to kink twist curl or bend so tightly that the fluid flow within the hose is blocked or reduced DO NOT use the hose to move attached equipment Periodically inspect the hose for wear because any of these conditions can damage the hose and result in personal injury 4 Hose material and coupler seals must be compatible with the hydraulic fluid used Hoses also must not come in contact with corrosive materials such as creosote impregnated objects and some paints Consult the manufac turer before painting a hose NEVER PAINT COUPLERS Hose deterioration due to corrosive material can result in personal injury 5 Some components in this set do not match the maximum pressure rating of the pump and ram USE A PRESSURE GAUGE IN THE SYSTEM TO MONITOR HYDRAULIC PRESSURE Refer to the instru
