Hydraulic bottle jack 2 ton h 148-278mm SKYWAY with valve in box+bag - The fully metal construction of components and assemblies ensures high reliability and failure resistance. The relief valve protects the jack from breaking if the load weight exceeds its capacity. User manual: Lifting: Using the groove at the end of the handle, tighten the locking valve by rotating the handle clockwise, place the jack under the object to be lifted by rotating the adjustable upper part of the piston, ensure a secure contact with the object's surface, insert the handle into the plunger lever and, by pumping the handle, raise the jack piston to the desired height. Lowering: Disconnect the handle, using the groove at the end of the handle, slowly turn the locking valve counterclockwise, the jack piston will gradually lower, do not rotate the valve sharply under load to avoid possible damage to the object during fast descent. Attention: When lifting a load, make sure the load is centered on the support plate. The weight of the lifted load should not exceed the capacity of the tool. Install the jack only on a flat and sturdy surface. Install the jack strictly at a right angle to the lifted object. Safety rules: When operating the product at temperatures of -5°C to +45°C, use GB443-64HJ-10 oil, at temperatures of -5°C to +20°C, use synthetic oil GB443-64. Maintain the proper oil level to ensure the specified lifting capacity of the jack. Before starting to lift the vehicle, ensure the reliable contact between the upper part of the jack piston and the lifted object. When using multiple jacks simultaneously, lift the object at an equal speed to avoid tipping the vehicle. Before starting work, make sure: The vehicle is parked with the parking brake engaged. The wheels are securely fixed with wheel chocks. The body and components of the jack do not have cracks or other damages. Prohibited: Using the jack as a permanent support element. Being under a vehicle lifted with a jack. Moving loads lifted by the jack. Using foreign objects to increase the lifting height of the jack. Specifications: Capacity: 2 tons. Minimum lifting height: 148 mm. Maximum lifting height: 283 mm. Piston lift height: 85 mm. Lifting of additional support: 50 mm. Net weight: 2.2 kg. Included in the set - packaging box and storage bag. The use of innovative valves in the design ensures a high level of safety and failure resistance of SKYWAY hydraulic jacks, significantly increasing their service life compared to analogues.
