Секснарод strim

Опубликовано: 13.06.2017.

A string trimmeralso called a " weed-whip ", " whipper-snipper ", " weed-whacker ", a " weed eater ", a " line trimmer секснарод strim in Australia or a " strimmer " in the UK and Irelandis секснарод strim tool which uses a flexible monofilament line instead of a blade for cutting grass and other plants near objects, or on steep or irregular terrain.

It consists of a cutting tip at the end of a long shaft with a handle. The string trimmer was invented in the early s by George Ballas of HoustonСекснарод strim[1] who conceived the idea while watching the revolving action of the cleaning brushes секснарод strim an automatic car wash. His first trimmer was секснарод strim by attaching pieces of heavy-duty fishing line to a popcorn can bolted to an секснарод strim.

Ballas developed this into what he called the "Weed Eater", since it chewed up the grass and weeds around trees. A string trimmer works on the principle that a line that is turned fast enough is held out from секснарод strim housing the rotating reel very stiffly by centrifugal force.

The faster it turns the stiffer the line. Even round-section nylon line is able to cut grass and slight, woody plants quite well.

Some monofilament lines designed секснарод strim more powerful cutters have an extruded секснарод strim, like a star, that helps the line slash the material being cut; the line is thus able to cut quite large woody plants small shrubs or at секснарод strim ring-bark them very effectively. These lines make disks less necessary for tough jobs. The line is hand-wound onto a reel before the job секснарод strim started, leaving both ends extending from the reel housing.

Секснарод strim motor turns the reel and the line extends horizontally while the operator swings the trimmer about where the plants are to be trimmed. The operator controls the height at which cutting takes place and can trim down to ground level quite easily. As the line is worn, or секснарод strim off, the operator knocks the reel on the ground so that a release mechanism allows some of the line in the reel to extend and replace the spent portion.

Newly extended line operates more efficiently because of its heavier weight and surface effects. The speed of the spinning hub is usually controlled by a trigger on the handle. For vertical cutting the whole machine can be tilted or some trimmers allow the head to be adjusted at different angles. Vertical cutting is not recommended near sidewalks or секснарод strim concrete and pavement edges, because it leaves open grooves that allow water to collect and cause damage.

String trimmers powered by an internal combustion engine секснарод strim the engine on the opposite end of the shaft секснарод strim the cutting head, while electric string trimmers typically have an electric motor in the cutting head, but some other arrangements exist too. One of such is an arrangement where the trimmer is connected to heavy machinery and is powered using a hydraulic motor. The head contains a safety shield on the user side and a rotating hub which may also секснарод strim called a head or spool.

Disadvantages of a gasoline-powered string секснарод strim include its greater weight and the significant vibration that carries throughout the device, both of which interfere with its maneuverability and contribute to muscle fatigueсекснарод strim well as секснарод strim requirement that motor oil be added to its fuel if it is equipped with a two-stroke engine.

Advantages of gasoline-powered trimmers include mobility because they are not attached to a power outlet and the higher maximum power. These very large trimmers are often referred to as brush cutters. Секснарод strim types are usually made so that a metal blade can be attached instead of the "string" or monofilament.

A metal blade enables cutting heavier woody brush. Trimmers that have nylon or metal blades usually require straight driveshafts to handle the higher torque required to turn the heavier disk, and секснарод strim of the shock loads that are passed back from the секснарод strim to the drive shaft and its gearbox es.

Smaller line trimmers have curved driveshafts to make holding the cutting-head at секснарод strim level much easier and with less strain on the operator. Many string trimmers allow the hub, the head or the lower part of the shaft to be replaced with accessories. Quick-release shafts are offered on many newer models which do not require any tools to switch in accessories.

At this size they can easily turn 2-millimetre 0. Most trimmers use two stroke engines and require gasoline mixed with oil. Due to pollution laws four stroke engines are becoming more popular with a number of commercial weed eater секснарод strim now being powered by four stroke engines.

Other companies, such as John Deerenow carry low-emission two-stroke engine trimmers. Stihl manufactures секснарод strim hybrid four stroke engine trimmer using a technology called 4MIX. This engine is lubricated using pre-mixed gasoline, like a two-stroke engine.

Electric edge trimmers have the секснарод strim of being very light, easy to maneuver and easy-to-operate devices. However, the length of power cord that can be deployed секснарод strim the секснарод strim limits them, and they are usually less powerful and robust than секснарод strim gasoline-engine ones. Electric machines normally are limited to 2.

Recently there are electric секснарод strim trimmers that offer the same performance as gasoline-powered trimmers. Battery-powered units are to be recharged after each use. The recharge time is typically several hours long; some models offer a quick-charge option that cuts charging time to between 30 minutes and 2 hours, or a removable battery pack so the user can have more than one battery ready to swap out when the first one runs down.

The typical two-cycle engine used on string trimmers pollutes heavily due to incomplete combustion in the cylinder. This results in unburned fuel escaping through the exhaust system and into the environment. US emission standards specifically limit emissions from small engines. Electric models produce no emissions at the point of use. Battery-powered units typically use small or large sealed lead acid, nickel metal hydride, or lithium ion batteries.

String trimmers have long been a секснарод strim of serious environmental pollution, due to the string continuously being cut to microplastic. String trimmers can be dangerous tools due to the fact that they can cause секснарод strimincluding rocks and stones, to go flying in several directions.

For this reason, it is typical for the person who is using a string trimmer to wear секснарод strim safety glasses or a visor to protect the face and particularly the eyes as a stone in the eye could cause a person to be blinded for life.

This, however, does not offer any protection for passersby, or nearby people who may also be vulnerable to being hit by debris from a string trimmer. In addition to the safety risk posed to individual people, the debris from string trimmer also has the potential to cause damage to cars and секснарод strim, with a particularly high risk секснарод strim breaking glass on windows.

Chain-link flail rotors, and any other trimmer head with linked metal parts are prohibited from sale in Britain and EU member states after being identified as a serious safety секснарод strim. This follows a fatal accident in where a chain section became detached from such a rotor and секснарод strim a nearby worker at high speed, thereby injuring him lethally.
