German SERMA tools SERMA models SERMA prices

SERMA tools refer to electrical safety tools, which are various specialized tools and devices designed to prevent accidents such as electric shock, burns, falls, and stumbling, thereby ensuring the personal safety of workers. In power systems, operators must carry and use various safety tools to complete tasks smoothly without causing personal injury. For example, electrical safety tools are required when inspecting operating electrical equipment, changing operating modes, or performing maintenance and tests; climbing safety tools are needed during line construction; when working on live electrical equipment or in areas near live equipment, insulating safety tools must be used to prevent electric shock or arc burns. Electrical safety tools can be divided into four categories: personal protective equipment, insulating safety tools, climbing tools, and warning signs.

SERMA tool features

1) Air is easily accessible, operates at low pressure, and used air can be vented locally without requiring return pipelines. 2) Air has low viscosity and minimal flow resistance loss, facilitating centralized supply and long-distance transmission. 3) Pneumatic actuators offer high movement speeds. 4) Pneumatic systems have strong environmental adaptability, reliably operating in wide temperature ranges, humid and dusty conditions; minor leaks do not pollute the environment, there is no risk of fire or explosion, ensuring safe usage. 5) Simple structure, easy maintenance, and low cost. 6) Long service life of pneumatic components. 7) Pneumatic components provide lower output force compared to hydraulics, faster motion, strong adaptability, and can operate in harsh environments such as flammable, explosive, dusty, humid, and impact-prone areas without polluting the environment; they offer long service life, simple construction, easy maintenance, and low price.

SERMA 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; while 24 teeth per inch are suitable for cutting metal sheets, metal pipes, and thin iron bars. 2) Push the saw forward, and lift it gently when pulling back. 3) Choose a wrench of appropriate size according to the nature of the work. 4) When using an adjustable wrench, apply force towards the fixed jaw, never towards the movable jaw. 5) If the wrench jaws are worn or slip during use, discontinue use immediately to prevent slipping. 6) Do not use a wrench as a hammer for striking. 5. Do not slide a pipe over the wrench handle 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 for testing current; do not use ordinary screwdrivers 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 collision or falling.

SERMA tool maintenance

1) Tooth set: The set is adjusted using a tooth setter. When setting the teeth, engage the slot of the setter with the saw teeth and push them firmly to the left or right. The degree of set must meet the requirements for the kerf width. 2) Filing: When filing the saw teeth, clamp the saw blade in a vise so that the teeth protrude. Depending on the size of the teeth, use a triangular steel file 100 to 200 mm in length. File each tooth sequentially from right to left, applying uniform pressure with both hands. One face of the file should be held vertically and closely against the lower cutting edge of the tooth, while the other face rests against the upper edge of the adjacent tooth. If the tooth set is found to be irregular, place the saw blade flat on a steel plate and use a wooden mallet to flatten all the teeth. Then, reset and refinish the teeth. In addition, maintain the saw frame; if damage is found in the ropes, nuts, knobs, or wooden mortise-and-tenon joints, adjust or repair them promptly.
