German HAIMER tools HAIMER models HAIMER prices

HAIMER tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism, are referred to as power tools. They are hand-held operating tools that use low-power electric motors or electromagnets as the power source to drive the working head via a transmission mechanism. Power tools are divided into two types: hand-held and portable. Hand-held power tools are more flexible, convenient, and widely used; many varieties have become essential tools for production and daily life. There are numerous power tool brands. Based on function and application, they are mainly classified into metal cutting power tools, grinding power tools, assembly power tools, and railway power tools. Common power tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.

HAIMER Tool Classification

1) Screwdriver: A tool used to turn screws to force them into position, typically with a thin wedge-shaped head that can be inserted into the slot or recess of the screw head—also known as a "screwdriver". 2) Wrench: A manual tool with an open end or box end that uses the lever principle to turn bolts, screws, nuts, and other threaded fasteners. Wrenches usually have jaws at one or both ends of the handle to apply external force; applying force to the handle allows turning the bolt or nut. When in use, apply external force to the handle 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. It is most commonly used to drive nails, correct shapes, or break apart objects. Hammers come in various forms; the common form consists of a handle and a head. One side of the head is flat for striking, while the other side is the hammer head. The shape of the hammer head can be like a claw (for pulling out nails) or wedge-shaped. There are also round-headed 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 end of the pen with your hand; otherwise, because the charged 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 a misjudgment that the charged object is not live. 5) Tape Measure: A tape measure is a commonly used measuring tool in daily life. Steel tape measures are frequently seen, commonly used in construction and decoration, and are also one of the essential household tools. They are divided into fiber tape measures, leather tapes, waist tapes, etc. Luban 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 "utility knife". It is frequently used in renovation, decoration, and signboard industries. 7) Electrician's Knife: An electrician's knife is a cutting tool commonly used by electricians. Ordinary electrician's knives consist of a blade, cutting edge, handle, and sheath. 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 blade section ending in a point, and the handle has a protection button to prevent the blade from snapping back. The blade of the electrician's knife integrates multiple functions; only one electrician's knife is needed to complete various operations for connecting wires, eliminating the need to carry other tools, offering benefits such as simple structure, ease of use, and multifunctionality. 8) Hacksaw: Includes hand saws (for household use, woodworking), pruning saws (for branch trimming), folding saws (for 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 horizontally. 10) Wire Pliers: Wire pliers are clamping and cutting tools composed of a head and handles. The head includes jaws, serrated grips, cutting edges, and wire cutters. The functions of the various parts of the pliers are: (1) The serrated grips can be used to tighten or loosen nuts; (2) The cutting edges can be used to strip the rubber or plastic insulation of 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 of the pliers have a voltage resistance of 500V or higher, allowing live wire cutting. 11) Needle-nose Pliers: Also called long-nose pliers, mainly used for cutting thin single-strand and multi-strand wires, bending loops for single-strand wire connectors, and stripping plastic insulation. They are also one of the commonly used tools for electricians (especially indoor electricians). They consist of a pointed tip, cutting edges, and handles. The handles of electrician's needle-nose pliers are covered with insulating sleeves rated for 500V. Due to the pointed head, needle-nose pliers are suitable for operations in narrow spaces. The method for bending wire connectors with needle-nose pliers is: first fold the wire end to the left, then bend it clockwise to the right tightly against the screw. 12) Wire Strippers: Wire strippers are one of the commonly used tools for indoor electricians, motor repair technicians, and instrument electricians; their appearance is shown in the figure below. They consist of cutting edges, wire crimping ports, 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 the insulation of plastic and rubber insulated wires and cable cores. The method of use is: place the wire end to be stripped into the blade opening of the plier head, squeeze the two handles together with your hand, then release, and the insulation will separate from the core wire.

HAIMER Tool Maintenance

1) Correct air supply system: The intake pressure at the tool inlet (not the air compressor outlet pressure) is generally 90PSIG (6.2Kg/cm^2). Pressure that is too high or too low will damage the tool's performance and lifespan. The intake air must contain sufficient lubricating oil to ensure adequate lubrication of the pneumatic motor inside the tool (place a white paper at the tool exhaust to check for oil stains; normal operation shows oil stains). The intake air must be free of moisture; it is inappropriate if compressed air has not passed through an air dryer. 2) Do not arbitrarily disassemble tool parts before operation, as this affects operator safety and may cause tool damage. 3) If the tool has minor faults or fails to achieve its original function after use, do not continue using it; inspect it immediately. 4) Regularly (approximately once a week) inspect and maintain the tool, adding grease (Grease) to rotating parts such as bearings, and adding oil (Oil) to the pneumatic motor parts. 5) When using various tools, strictly adhere to all safety regulations and operating instructions. 6) Select appropriate tools for the work; tools that are too large can easily cause work injuries, while tools that are too small can easily cause tool damage.

HAIMER Tool Usage

1) Before use, carefully inspect the tool to 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; the value must not be lower than O.5 megohms. See the attached table for insulation resistance values. 2) Hand-held power tools with metal housings must have a reliable protective grounding wire. The power cord should be a multi-core soft rubber sheathed cable, and the grounding protection wire at both ends must be securely connected. 3) Hand-held power tools should be operated by dedicated personnel with certain professional knowledge. Strictly observe relevant safety operating procedures during use. 4) Before use, first check whether the related electrical protection devices and mechanical protection devices are intact and functioning normally. Also pay attention to whether the rotating parts rotate flexibly without sticking. 5) When using Class I hand-held power tools, users must wear prescribed protective equipment and set up qualified protective gear. Take corresponding 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 hand-held power tools in damp and narrow places, install a leakage switch with a working current of less than 1.5mA and an action time of less than or equal to 0.1 seconds. The leakage switch should be placed inside the container and supervised by a dedicated person. 6) Occupational hazards of using hand-held power tools. Arm vibration disease caused by long-term hand-transmitted vibration work was listed as one of China's statutory occupational diseases as early as 1957, also known as local vibration disease, typically manifested as episodic white finger.
