If any shipping damage isfound, notify carrier at once. Shipping damage is NOT covered by warranty. The carrieris responsible for all repair or replacement cost resulting from damage in shipment.SAFETY INFORMATIONWARNINGSTAY CLEAR OF LOADS SUPPORTED BY HYDRAULICS.A cylinder, when used as a load lifting device, should never beused as a load holding device. After the load has been raised,it should be blocked.WARNINGDO NOT EXCEED EQUIPMENT RATINGS.– Never attempt to lift a load weighing more than the capacityof the cylinder. Overloading causes equipment failure andpossible personal injury.– These cylinders are designed for a maximum pressure of10,000 psi (700 bar). Do not connect these cylinders to apump with a higher pressure rating.
WARNINGBE SURE SETUP IS STABLE BEFORE LIFTING LOAD.– The cylinder should be placed on a flat surface that can supportthe load. Where applicable, use a cylinder base for addedstability. Do not weld or otherwise modify the cylinder toattach a base or other support.– Avoid situations where loads are not directly centered on thecylinder plunger. Off-center loads produce considerablestrain on cylinders and plungers. In addition, the load may slipor fall, causing potentially dangerous results.– Distribute the load evenly across the entire saddle surface. Tiltsaddles are available to reduce offset loading (except 100ton models). Always use a saddle to protect the plungerwhen threaded attachments are not used.WARNINGUSE ONLY RIGID PIECES TO HOLD LOADS. Carefullyselect steel or wood blocks that are capable of supporting theload. Never use a hydraulic cylinder as a shim or spacer in anylifting or pressing application.WARNINGONLY USE HYDRAULIC CYLINDER IN ACOUPLED SYSTEM.Never use a cylinder with unconnected couplers. If the cylinderbecomes extremely overloaded, the coupler check ball and/orhydraulic oil may shoot out of the cylinder causing severepersonal injury.2
CAUTIONAVOID DAMAGING HYDRAULIC HOSE.– Avoid sharp bends and kinks when routing hydraulic hoses.Using a bent or kinked hose will cause severe back-pressure.Also, sharp bends and kinks will internally damage the hoseleading to premature failure.– Do not drop heavy objects on hose. A sharp impact maycause internal damage to hose wire strands. Applyingpressure to a damaged hose may cause it to rupture.– Do not use the hydraulic hose to carry a hydraulic component(i.e. pumps, cylinders and valves).CAUTIONKEEP HYDRAULIC EQUIPMENT AWAY FROMFLAMES AND HEAT.Excessive heat will soften packings and seals, resulting influid leaks. Heat also weakens hose materials and packings.For optimum performance DO NOT expose equipment totemperatures of 150oF (65oC) or higher. Protect hoses andcylinders from weld spatter.3
INSTALLATION1. Make hydraulic connections. Use a pump with a releasevalve or a 3-way valve and one hose for single-actingcylinders (1). Use a pump with a 4-way valve and twohoses for double-acting cylinders (2).IMPORTANT: Double-acting cylinders must have bothcouplers connected.Fully hand-tighten all couplers. Loose coupler connections will block the flow ofoil between the pump and the cylinder.2. Remove air from the cylinder as shown below.Single-acting cylinders: Position the cylinder so that the plunger is pointed down andthe cylinder lower than the pump. Fully extend and retract the cylinder 2 or 3 times.Double-acting cylinders: Lay the cylinder on its side and have the couplersfacing up. Fully extend and retract the cylinder 2 or 3 times.NOTE: Collar threads are rated for the full capacity of the cylinder when fullyengaged in attachments.NOTE: The use of cylinder attachments or extensions reduces the cylinder capacity byat least 50%.4
OPERATIONWARNINGDO NOT HANDLE PRESSURIZED HOSES. Escaping oilunder pressure can penetrate the skin,causing serious injury. If oil is injected under the skin, see adoctor immediately.Operate the hydraulic pump to advance and retract the cylinder.Some single-acting cylinders are spring-return, others are load return. The speed ofretraction is affected by the length of the hose and other restrictions in the line. Doubleacting cylinders are powered in both directions by the pump.The cylinder stop ring is designed to take the full load. However, to reduce cylinderwear, use less than full stroke when possible.MAINTENANCE1. Use dust caps when cylinders are disconnected from the hose. Keep entirecylinder clean to prolong cylinder life.2. Store cylinders up-right to prevent seal distortion.5
TROUBLE SHOOTINGThese cylinders should be repaired only by Authorized ESCO Technical ServiceCenters. Single-acting cylinders are spring loaded and require special disassemblytechniques to prevent personal injury.PROBLEMCylinder will not advance.POSSIBLE CAUSESPump release valve open.Coupler not fully tightened.Oil level in pump is low.Pump malfunctioning.Load is too heavy for cylinder.Cylinder advances part way.Oil level in pump is low.Coupler not fully tightened.Cylinder plunger binding.Cylinder advances in spurts.Air in hydraulic system.Cylinder plunger binding.Cylinder advances slower than normal.Leaking connection.Coupler not fully tightened.Pump malfunctioning.Cylinder advances but will not hold.Cylinder seals leaking.Pump malfunctioning.Leaking connection.Incorrect system set-up.Cylinder leaks oil.Worn or damaged seals.Internal cylinder damage.Loose connection.Cylinder will not retract or retracts slower than normal.Pump release valve is closed.Coupler not fully tightened.Pump reservoir over-filled.Narrow hose restricting flow.Broken or weak retraction spring.Cylinder damaged internally.Oil leaking from external relief valve.Coupler not fully tightened.Restriction in return line.6

The scheme of the hydraulic cylinder is shown in Fig. 1a. The hydraulic cylinder consists of a cylinder barrel, in which a piston connected to a piston rod moves back and forth. The barrel is closed on each end by the cylinder bottom (also called the cap end) and by the cylinder head where the piston rod comes out of the cylinder.
