German OTTER tools OTTER models OTTER prices

OTTER tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism, are called power tools. They are hand-held operating tools that use low-power electric motors or electromagnets as power sources to drive the working head via a transmission mechanism. Power tools are divided into handheld and portable types; handheld 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. According to their functions and applications, they are mainly classified into metal-cutting power tools, grinding power tools, assembly power tools, and railway-specific power tools. Common power tools include electric drills, electric grinders, electric wrenches and screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.

OTTER tool types

1) Frame saw. Also known as a buck saw, it consists of an H-shaped wooden frame, twisted rope with toggle, and saw blade. The two ends of the saw blade are fixed to the frame with knobs, which can also adjust the angle of the blade. After tightening the twisted rope, the blade is tensioned and ready for use. Frame saws are classified into coarse, medium, and fine types based on blade length and tooth pitch. Coarse saw blades are 650–750mm long, with a tooth pitch of 4–5mm; coarse saws are mainly used for cutting thicker lumber. Medium saw blades are 550–650mm long, with a tooth pitch of 3–4mm; medium saws are mainly used for cutting thin lumber or cutting tenons. Fine saw blades are 450–500mm long, with a tooth pitch of 2–3mm; fine saws are mainly used for cutting finer wood and cutting tenon shoulders. 2) Knife saw. A knife saw mainly consists of a cutting edge and a handle, and can be classified into single-sided, double-sided, and backed knife saws. Single-sided knife saws have a blade length of 350mm, with teeth on one side; depending on the function of the teeth, they can be divided into rip-cut and cross-cut types. Double-sided knife saws have a blade length of 300mm, with teeth on both sides; typically, one side is for rip-cutting and the other for cross-cutting. Backed knife saws have a blade plate length of 250–300mm; the back of the blade is reinforced with a steel strip, and the teeth are finer, available in rip-cut and cross-cut versions. 3) Groove saw. A groove saw consists of a handle and a saw blade, with the blade approximately 200mm long. Groove saws are mainly used for cutting grooves in wood. 4) Panel saw. Also known as a hand saw, it consists of a handle and a saw blade, with the blade approximately 250–750mm long and a tooth pitch of 3–4mm. Panel saws are mainly used for cutting wider boards. 5) Keyhole saw. The blade is narrow and long, with a pointed tip, approximately 300–400mm in length. Keyhole saws are mainly used for cutting small holes and slots. 6) Coping saw. Also known as a fret saw, its construction is similar to that of a frame saw, but the blade is narrower (approximately 10mm), mainly used for cutting arcs and curves. 7) Wire saw. Also known as a bow saw, it is made by bending a bamboo strip into a bow shape, with wire stretched between the two ends. Sawtooth-like projections are cut into the wire, using the sharp edges of these projections for cutting. The wire is approximately 200–600mm long, and the bow frame is 800–900mm long. Wire saws are mainly used for cutting complex curves and openings.

OTTER tool structure and components

The function of the power component is to convert the mechanical energy of the prime mover into hydraulic pressure energy. This refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps, and piston pumps. The function of actuating components (such as hydraulic cylinders and hydraulic motors) is to convert hydraulic pressure energy into mechanical energy, driving loads to perform linear reciprocating motion or rotary motion. Control components (i.e., various hydraulic valves) control and regulate the pressure, flow, and direction of the fluid in the hydraulic system. Depending on the control function, hydraulic valves can be divided into pressure control valves, flow control valves, and directional control valves. Pressure control valves are further divided into relief valves (safety valves), reducing valves, sequence valves, pressure relays, etc.; flow control valves include throttle valves, adjustment valves, and flow divider/combiner valves; directional control valves include check valves, pilot-operated check valves, shuttle valves, and directional control valves. Depending on the control method, hydraulic valves can be divided into on/off control valves, fixed-value control valves, and proportional control valves. Auxiliary components include oil tanks, oil filters, oil pipes and pipe fittings, sealing rings, pressure gauges, and oil level/temperature indicators. Hydraulic oil is the working medium that transmits energy in hydraulic systems, including various mineral oils, emulsions, and synthetic hydraulic oils.

OTTER 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 less than O.5 megohms. Refer to the attached table for insulation resistance values. 2) Handheld power tools with metal housings must have a reliable protective grounding wire. The power cord should be a multi-core soft rubber-sheathed cable, with the grounding protection wire securely connected at both ends. 3) Handheld power tools should be operated by dedicated personnel with appropriate professional knowledge. Strictly adhere to relevant safety operating procedures during use. 4) Before use, check whether the related electrical and mechanical protection devices are intact and functioning normally. Also ensure that the rotating parts move flexibly without sticking. 5) When using Class I handheld power tools, operators 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 operator wear insulating gloves, insulating shoes, or stand on an insulating mat. When using Class II handheld power tools in damp and confined spaces, install a residual current circuit breaker (RCCB) with an operating current of less than 1.5mA and an operating time of ≤ 0.1 seconds. The RCCB should be placed inside the container and monitored by dedicated personnel. 6) Occupational hazards associated with using handheld power tools. Arm vibration disease caused by long-term exposure to hand-transmitted vibration was listed as one of China's statutory occupational diseases as early as 1957, also known as local vibration disease, typically characterized by episodic white finger.
