Unit Safety Instructions

JIMMY SERIES HYDRAULIC REBAR BENDERS — RULES FOR SAFE OPERATION

■All hose connections must be tightened with the proper tools before operating hydraulic power unit. DO NOT over tighten. Connections should only be tightened securely and leak-free. Over tightening can cause premature thread failure or high-pressure fittings to split at pressures lower than their rated capacities.

■Should a hydraulic hose ever rupture, burst, or need to be disconnected, immediately shut off the pump and release all pressure. NEVER attempt to grasp a leaking pressurized hose with your hands.The force of escaping hydraulic fluid could cause serious injury.

■NEVER subject the hose to potential hazard such as fire, sharp surfaces, extreme heat or cold, or heavy impact. DO NOT allow the hose to kink, twist curl, crush, cut, or bend so tightly that the fluid flow within the hose is blocked or reduced. Periodically inspect the hose for wear, because any of these conditions can damage the hose and possibly result in personal injury.

■NEVER use the hose to move attached equipment. Stress can damage the hose and possibly cause personal injury.

■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. Hose deterioration due to corrosive materials can result in personal injury. Consult the manufacturer before painting a hose. NEVER paint a coupler.

■Use only approved accessories and approved hydraulic fluid. Hoses, seals and all components used in a system must be compatible with the hydraulic fluid used.

■DO NOT exceed the rated capacities of the cylinders. Excess pressure can result in personal injury.

■Inspect each cylinder and coupler before each shift or usage to prevent unsafe conditions from developing.

■DO NOT use cylinders if they are damaged, altered or in poor condition.

■DO NOT use cylinders with bent or damaged couplers or damaged port threads.

■NEVER use extreme heat to disassemble a hydraulic cylinder or ram. Metal fatigue and/or seal damage will result and can lead to unsafe operating conditions.

DANGER - High Pressure Hazard

When extending a cylinder or ram under load, always insure that the couplers or port threads have not been damaged or do not come in contact with any rigid obstruction. If this condition does occur, the coupler’s attaching threads may

become stripped or pulled from the cylinder or ram resulting in the instantaneous release of high pressure hydraulic fluid, flying objects, and loss of the load. All of these possible results could cause serious injury or even death.

CAUTION - System Evaluation

Cylinder hoses, couplings and hydraulic pump must all be rated for the same operating pressure, correctly connected and compatible with the hydraulic fluid used. An improperly matched system could cause the system to fail and possibly cause serious injury. Always maintain the correct operating for optimal performance. If you have any questions, please contact your nearest MQ service center.

■Avoid pinch points or crush points that can be created by the load or parts of the cylinder. Do not wear loose jewelry when operating the rebar bender.

WARNING

Moving parts can crush and cut.

ALWAYS keep hands clear of rollers while rebar bender is operating.
