German jas tools jas models jas prices

jas 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 dedicated to 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. A complete hydraulic tool system consists of five components: power elements, actuating elements, control elements, auxiliary elements, and hydraulic oil.

jas tool classification

1) Screwdriver: A tool used to turn screws to seat them, typically featuring a thin wedge-shaped tip that inserts into the slot or recess of the screw head—also known as a "screwdriver". 2) Wrench: A hand tool with an open end or box end that uses the lever principle to turn bolts, screws, nuts, and other threaded fasteners. Wrenches typically have jaws at one or both ends of the handle; applying external force to the handle allows turning of the bolt or nut. Apply external force along the direction of thread rotation to turn the bolt or nut. 3) Hammer: A tool used to strike objects to move or deform them. Most commonly used for driving nails, straightening, or splitting objects. Hammers come in various forms; a common form consists of a handle and a head. One face of the head is flat for striking, while the other is the hammer head. The hammer head can be shaped like a claw (for pulling nails) or wedge-shaped. There are also ball-peen hammer heads. 4) Test pen: Also called a voltage tester pen, abbreviated as "electric pen". It is an electrical tool used to test whether wires are live. The pen body contains a neon bulb; if the neon bulb lights up during testing, it indicates that the wire is live or is the live wire of a circuit. The tip and tail of the test pen are made of metal, while the pen shaft is made of insulating material. When using a test pen, you must touch the metal part at the tail end with your hand; otherwise, because the live object, test pen, human body, and earth do not form a circuit, the neon bulb in the test pen will not light up, leading to misjudgment that the live object is not energized. 5) Tape measure: A commonly used measuring tool in daily life. Steel tape measures are frequently seen, commonly used in construction and decoration, and are essential household tools. Types include fiber tape measures, leather tapes, waist tapes, etc. Lu Ban rulers, Feng Shui rulers, and Wen Gong rulers also belong to the category of steel tape measures. 6) Utility knife: A type of knife with a sharp blade used for cutting wallpaper and similar materials, hence the name "wallpaper knife," also known as a "craft knife." Frequently used in renovation, decoration, and signboard industries. 7) Electrician's knife: A cutting tool commonly used by electricians. A standard electrician's knife consists of a blade, cutting edge, handle, and clip. When not in use, retract the blade into the handle. The root of the blade is hinged to the handle, featuring scale lines and markings; the front end forms a screwdriver tip, both sides have file surfaces, the cutting edge has an inwardly curved notch ending in a point, and the handle has a safety button to prevent accidental blade retraction. The electrician's knife blade integrates multiple functions, allowing various wire connection operations to be completed with just one tool without carrying others, offering benefits such as simple structure, ease of use, and versatility. 8) Hacksaw: Includes hand saws (household, woodworking), pruning saws (branch trimming), folding saws (branch trimming), bow saws, veneer saws (woodworking), rip saws (woodworking), and crosscut saws (woodworking). 9) Spirit level: A spirit level contains a bubble vial and can be used to inspect, measure, and debug whether equipment is installed level. 10) Combination pliers: Combination pliers are clamping and cutting tools consisting of a head and handles. The head includes jaws, serrated grips, cutting edges, and wire cutters. The functions of the plier parts are: (1) The serrated grips can be used to tighten or loosen nuts; (2) The cutting edges can be used to strip rubber or plastic insulation from soft wires, and also to cut wires and iron wires; (3) The wire cutters can be used to cut harder metal wires such as electrical wires and steel wires; (4) The insulating plastic sleeves on the pliers withstand voltages above 500V, allowing live wire cutting. 11) Needle-nose pliers: Also called long-nose pliers, mainly used for cutting fine single-strand and multi-strand wires, bending loops on single-strand wire terminals, and stripping plastic insulation. They are also commonly used by electricians (especially indoor electricians). They consist of pointed tips, cutting edges, and handles. The handles of electrician's needle-nose pliers are covered with insulating sleeves rated for 500V. Due to their pointed tips, they are suitable for operations in narrow spaces. To bend wire terminals with needle-nose pliers: first fold the wire end to the left, then bend it clockwise to the right against the screw. 12) Wire strippers: Wire strippers are commonly used tools for indoor electricians, motor repair technicians, and instrumentation electricians; their appearance is shown below. They consist of cutting edges, wire crimping slots, and handles. The handles of wire strippers are covered with insulating sleeves rated for a working voltage of 500V. Wire strippers are suitable for stripping insulation from plastic and rubber insulated wires and cable cores. Usage: Place the wire end to be stripped into the blade opening of the head, squeeze the two handles together with your hand, then release; the insulation will separate from the core wire.

jas tool selection guide

1) Distinguish between household and professional use based on needs. Most power tools are designed for professionals; differentiate between professional and general household tools when purchasing. The difference usually lies in power rating; professional tools have higher power to reduce workload for professionals, while household tools have smaller workloads and thus do not require high input power. 2) The tool's outer packaging should have clear patterns, no damage, a sturdy plastic case, and durable latches. 3) The tool's appearance should have uniform color; plastic surfaces should have no visible flow marks or indentations, scratches, or impact marks. Assembly misalignment between housing parts should be ≤ 0.5mm. Aluminum castings should have smooth, attractive coatings without defects. The entire unit surface should be free of oil and stains. When holding, the switch handle should be flat. Cable length should generally be no less than 2 meters. 4) Nameplate parameters should match those on the CCC certificate. The manual should include the manufacturer's and factory's detailed address and contact information. The nameplate or certificate should include a traceable batch number. 5) Hold the tool, connect to power, and frequently operate the switch to start the tool repeatedly. Observe whether the switch on/off function is reliable. Simultaneously observe nearby TVs and fluorescent lights for abnormalities to confirm the tool is equipped with an effective radio interference suppressor. 6) Run the tool for one minute. While running, hold the tool; you should not feel any abnormal vibration. Observe commutation sparks; commutation spark level should not exceed 3/2. Generally, looking into the air inlet, there should be no obvious arcing on the commutator surface. There should be no abnormal noise during operation.

jas tool precautions

1) Before use, inspect hand tools for damage. Do not use unsafe tools. 2) Keep tools clean, especially the gripping areas, to prevent slipping during work. 3) Wear appropriate personal protective equipment such as goggles and gloves. 4) Use hand tools with correct posture and technique; maintain stable force application for safety, and avoid excessive force. 5) When using sharp tools, do not point blades or sharp parts towards others. 6) When not in use, protect blades or sharp parts with guards. Avoid carrying tools by hand or keeping them in pockets. 7) Do not misuse hand tools for other purposes. 8) Understand the characteristics of each hand tool and use them correctly.
