Operation is explained in Section 5. 3.1.5.For ground condition requirements, see Section 1 Safety. 3.1.6.For information on parts and materials requiring specialized repair techniques see Section 6 Maintenance. 4. ASSEMBLY/STORAGE 4.1. ASSEMBLY 4.1.1.Unpack the product and check contents against the parts list included with these instructions. Should there be any damaged or missing parts contact your supplier immediately. We recommend two people assemble the crane. 4.1.2.Lay out all the parts in the appropriate positions ready for assembly. 4.1.3.When assembling, ensure that you fit a plain washer, then a locking washer before fitting nuts on to bolts. fig.2 4.1.4.Assemble the crane main frame first, leaving the hydraulic ram assembly until last. NOTE: At this stage all nuts and bolts should be finger tight only. 4.1.5.Connect the base of the ram assembly to the ram assembly mounting. 4.1.6.Raise the lift arm and carefully move it until the ram fits the arm bracket. Engage the pin and secure with the fasteners provided. 4.1.7.Now tighten all the nuts and bolts on the main frame. Assemble and insert the legs and locate with the lock pins provided. 4.1.8.Before using crane place the pumping handle on the release valve and turn anti-clockwise. With the handle inserted in the pump socket, pump 20 times through the full stroke, thus bleeding from the hydraulic system any air which may have entered during transit. 4.2. STORAGE 4.2.1.Always store the crane fully closed so that the jib is in lowest position and the ram is closed (fig.2). 4.2.2.To save space the legs may be folded into the upright position and secured in place using the lock pins (fig.2). 5. OPERATION Refer to Section 6.2 regarding inspection before each and every use NOTE: ENSURE YOU HAVE READ AND UNDERSTOOD THE SAFETY INSTRUCTIONS AT THE BEGINNING OF THIS SECTION BEFORE YOU OPERATE THE CRANE. 5.2.1.Use the pump handle recess to tighten the release valve, turning firmly clockwise. 5.2.2. Place handle into pump socket and pump, the jib will raise. Continue to pump until the jib reaches the height at which the load can be secured. 5.2.3. Connect the crane hook to the load using a suitable certified sling or support beam. Ensure you are aware of the load weight, and check that it is within the capacity of the crane (at the jib extension you are using) and the sling or support beam. When removing engines ensure you know the weight to be lifted. Use only the lifting points recommended by the vehicle manufacturer. 5.2.4.Lift only from directly above the load. DO NOT LIFT THE LOAD AT AN ANGLE! 5.2.5. To lower load, position handle on release valve at base of ram and turn VERY SLOWLY anti-clockwise avoiding any sudden movement. 8 DO NOT allow the load to drop suddenly. 5.2.6. The crane is not a transportation device but may be used to reposition the load being worked on. To do so, lower load and jib with care, to the lowest possible point before attempting to move. DO NOT try to move crane in a sideways direction. The crane is not designed to support the load indefinitely. When you have repositioned the load, lower the load onto a secure and appropriate working base, being fully aware of your own and other persons locations in relation to the lowering load. © Jack Sealey Limited Original Language Version SC10.V4 Issue 4 (3) 26/05/21
