Compared with traditional&hellip;\" class=\"encyclopedia\">hydraulic jack<\/a> is an extremely practical tool. It is generally very wear-resistant. However, hoses, lines, sleeves, and valves can become leaky over time. The internal sealing rings in the cylinder also degrade over time. External leaks are easy to detect. They should be rectified immediately, as the device is no longer safe if it is leaking.     <\/p><p>Internal leaks are indicated by the load gradually sinking again. In this case, too, the <a href=\"https:\/\/www.bf-hydraulik.com\/en\/hydraulic-jack\/\" target=\"_self\" title=\"Hydraulic jack: lifting heavy loads with little effortHydraulic jacks are technically sophisticated tools that can be used to move even very large loads with minimal muscle power. Compared with traditional&hellip;\" class=\"encyclopedia\">hydraulic jack<\/a> should be disassembled and repaired. Spare parts are readily available for branded devices.  <\/p><p>When lowering the lifted load, the <a href=\"https:\/\/www.bf-hydraulik.com\/en\/check-valve\/\" target=\"_self\" title=\"Check ValveA check valve allows the flow of the medium to pass through in only one direction. In most applications, the medium is a fluid, hydraulic fluid, or gas. In&hellip;\" class=\"encyclopedia\">check valve<\/a> should only be opened carefully. Even a slight turn of the screw will cause the piston to retract. Caution: if the valve is opened too quickly, there is a high risk of injury due to the sudden descent of the load.
