German fetra tools fetra models fetra prices

fetra tools integrate hydraulic systems with conventional tools into a unified whole. They convert powerful hydraulic power into mechanical motions such as reciprocating linear motion, rotary motion, and cycloidal motion. A complete hydraulic tool system consists of five components: power elements, actuating elements, control elements, auxiliary elements, and hydraulic oil. Hydraulic tools include: hydraulic wrenches, electric pumps for hydraulic wrenches, hydraulic jacks, hydraulic bolt tensioners, hydraulic flange spreaders, hydraulic nut splitters, hydraulic pullers, etc. Hydraulic tools offer the advantages of high efficiency and convenience.

fetra tool applications and usage

The electric hydraulic oil pump can serve as the hydraulic pump for various hydraulic devices. When equipped with other hydraulic tools, the electric hydraulic oil pump enables tasks such as lifting, pressing, pipe bending, bar bending, straightening, shearing, assembly, and disassembly. This reduces labor intensity and improves work efficiency. During use, open the air release nut, open the valve on the oil collection block, connect the power supply, and attach the quick coupler to the quick plug on the corresponding hydraulic device. Press the power switch; after the motor runs for 1-2 minutes, close the switch to set it to the pressure-boosting state. At this point, the output hydraulic oil will perform various tasks, self-pressurizing as the load increases until 63MPA. After work is completed, open the valve to relieve pressure. Once the hydraulic oil has returned, remove the quick coupler, tighten the air release nut, unplug the power cord, and close the valve.

fetra tool usage

1) Select the appropriate saw blade for the workpiece. For example, use 14 teeth per inch for cutting solid or thick soft metals; use 18 teeth per inch for tool steel, iron pipes, and hard metals; and use 24 teeth per inch for cutting metal sheets, metal pipes, and thin iron bars. 2) Push the saw forward, and lift it slightly when pulling back. 3) Select a wrench of appropriate size according to the nature of the work. 4) When using an adjustable wrench, apply force to the fixed jaw, never to the adjustable jaw. 5) If the wrench jaws are worn or slip during use, do not continue using them to prevent slipping. 6) Do not use a wrench as a hammer for striking. 5) Do not fit a pipe over the handle end of a wrench to increase torque. 7) Press the inner side of the first leg of the square against the edge of the wooden board, and draw along the inner side of the second leg with a pencil to mark a perpendicular line. 8) Select the appropriate screwdriver based on the size and shape of the screw head slot. 9) Do not strike the screwdriver handle with a hammer; replace handles that are damaged immediately. 10) Do not use a screwdriver as a chisel or lever. 11) Use an electrician's screwdriver to test current; do not use a standard screwdriver to test high voltage. 12) Do not grind the screwdriver tip to avoid damaging the hardened surface. 13) Do not keep screwdrivers in shirt or trouser pockets to prevent injury from collisions or falls.

fetra tool usage

1) Inspect carefully before use. Ensure there is no external damage, the switch operates flexibly without sticking, and the power cord and tool housing are intact. Use a 500V megohmmeter to measure the insulation resistance between the winding and the housing; it must not be less than O.5 megohms. See the attached table for insulation resistance values. 2) Handheld electric tools with metal housings must have a reliable protective ground wire. The power cord should be a multi-core soft rubber-sheathed cable, with the ground protection wire securely connected at both ends. 3) Handheld electric tools should be used by dedicated personnel with appropriate professional knowledge. Strictly adhere to relevant safety operating procedures during use. 4) Before use, check that all related electrical and mechanical protective devices are intact and functioning normally. Also ensure that rotating parts move flexibly without sticking. 5) When using Class I handheld electric tools, users must wear prescribed protective equipment and use qualified protective gear. Take appropriate anti-electric shock safety measures as required, such as installing residual current devices (RCDs) in the power circuit, or having the user wear insulating gloves, insulating shoes, or stand on an insulating mat. When using Class II handheld electric tools in damp, confined spaces, install a leakage protection switch with an operating current of less than 1.5mA and an operating time of less than or equal to 0.1 seconds. The leakage protection switch should be placed inside the container and monitored by dedicated personnel. 6) Occupational hazards of using handheld electric tools. Arm vibration disease caused by long-term exposure to hand-transmitted vibration was listed as one of China's statutory occupational diseases in 1957, also known as local vibration disease, typically manifested by episodic white finger.
