If any shipping damage is found, notify carrier at once. Shipping damage is NOT covered by warranty.
WARNING BE SURE SETUP IS STABLE BEFORE LIFTING LOAD. – The cylinder should be placed on a flat surface that can support the load. Where applicable, use a cylinder base for added stability. Do not weld or otherwise modify the cylinder to attach a base or other support. – Avoid situations where loads are not directly centered on the cylinder plunger. Off-center loads produce considerable strain on cylinders and plungers. In addition, the load may slip or fall, causing potentially dangerous results.
CAUTION AVOID 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 hose leading to premature failure. – Do not drop heavy objects on hose. A sharp impact may cause internal damage to hose wire strands. Applying pressure 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).
INSTALLATION 1. Make hydraulic connections. Use a pump with a release valve or a 3-way valve and one hose for single-acting cylinders (1). Use a pump with a 4-way valve and two hoses for double-acting cylinders (2). IMPORTANT: Double-acting cylinders must have both couplers connected. Fully hand-tighten all couplers. Loose coupler connections will block the flow of oil between the pump and the cylinder. 2. Remove air from the cylinder as shown below.
OPERATION WARNING DO NOT HANDLE PRESSURIZED HOSES. Escaping oil under pressure can penetrate the skin, causing serious injury. If oil is injected under the skin, see a doctor immediately. Operate the hydraulic pump to advance and retract the cylinder. Some single-acting cylinders are spring-return, others are load return. The speed of retraction is affected by the length of the hose and other restrictions in the line. Doubleacting cylinders are powered in both directions by the pump.
TROUBLE SHOOTING These cylinders should be repaired only by Authorized ESCO Technical Service Centers. Single-acting cylinders are spring loaded and require special disassembly techniques to prevent personal injury. PROBLEM Cylinder will not advance. POSSIBLE CAUSES Pump 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.
