description of a manual can openerAlthough they are simple, they are not all created equal. Cheap can openers may be uncomfortable on the hand and difficult to use, while more expensive, better-made openers function smoothly and last for many years. Handles The body of a manual can opener consists of two handles connected with a single rivet or bolt, allowing them to be drawn apart and pushed together, pivoting on the point where they are joined. Higher-quality can openers have rubber grips on the handles, making them easier and more comfortable to grip. Crank A crank that can be turned by hand is attached to one of the handles. The axle of the crank goes through the handle and has the traction gear attached to the other side. When you use the can opener to open a can, you separate the handles of the opener, place the traction gear beneath the lip of the can and the cutting wheel above it, then bring the handles together, trapping the lip of the can between the traction gear and the cutting wheel. With the opener in this position, you can turn the crank to turn the traction gear and propel the cutting wheel around the rim of the can. Traction Gear The traction gear is a small, round metal wheel with notches in it to increase its grip on the lip of the can. When it and the cutting wheel are pressed tightly against opposite sides of the lip of the can, the pressure against the surface of the traction gear causes it to grip the surface of the metal can when you turn the crank. Cutting Wheel The cutting wheel has a sharp edge around its circumference. When you force the cutting wheel against the metal of the can by pushing the handles of the opener together, its sharp edge cuts through the metal. When you turn the traction gear by rotating the gear, the cutting wheel rotates as well, cutting through the metal as it advances around the lip of the can. His primary areas of writing include surrealism, Buddhist iconography and environmental issues.http://www.flying-vikings.net/UserFiles/bosch-motion-detector-manual.xml

Although preservation of food using tin cans had been practiced since at least 1772 in the Netherlands, the first can openers were not patented until 1855 in England and 1858 in the United States. These early openers were basically variations of a knife, though the 1855 design continues to be produced. The first can opener, consisting of the now familiar sharp rotating cutting wheel that runs round the can's rim to cut open the lid, was invented in 1870, but was considered very difficult to operate for the ordinary consumer. A successful design came out in 1925 when a second, serrated wheel was added to hold the cutting wheel on the rim of the can. This easy-to-use design has become one of the most popular can opener models.These featured a robust and compact design with a pull cutting blade hinged to a corrugated handle with a pivot. Electric can openers were introduced in the late 1950s and met with success. The development of new can opener types continues with a recent redesign of a side-cutting model.Freshly caught salmon were cleaned, boiled in brine, smoked and placed in tin-plated iron boxes. This canned salmon was known outside the Netherlands, and in 1797 a British company supplied one of their clients with 13 cans. Preservation of food in tin cans was patented by Peter Durand in 1810. The patent was acquired in 1812 by Bryan Donkin, who would later set up the world's first canning factory in London in 1813.Each food-type had its own can-type, and came with its own can-opener-type. Tinned fish and meat were sold in rectangular cans.It consisted of a sharp sickle, which was pushed into the can and sawed around its edge. A guard kept the sickle from penetrating too far into the can.http://www.kosmetykalekarska.pl/_kosmetykalekarska/bosch-mono-jetronic-manual.xml The opener was made of cast iron and had a very similar construction to the Yeates opener, but featured a more artistic shape and was the first move towards improving the look of the can opener.Then, the length of the lever had to be adjusted to fit the can size, and the lever fixed with the wingnut.It featured the now standard pliers-type handles, when squeezed would tightly grip the can rim, while turning the key would rotate the cutting wheel, progressively cutting the lid along the rim.The left end is a can piercer and the right end is a bottle cap lifter. The same opener was used for piercing those cans.The P-38 and P-51 are small can openers with a cutter hinged to the main body. The P-38 can opener is keychain -sized, about 1.5 inches (38 mm) long, and consists of a short metal blade that serves as a handle (and can also be used as a screwdriver ), with a small, hinged metal tooth that folds out to pierce the can lid. A larger version, called P-51, is somewhat easier to operate. P-38 was developed in 1942 and was issued in the canned field rations of the United States Armed Forces from World War II to the 1980s. The P-38 and P-51 are cheaper to manufacture and are smaller and lighter to carry than most other can openers. As with some other military terms (e.g., jeep ), the origin of the term is not known with certainty. The P-38 and P-51 openers share a designation with the Lockheed P-38 Lightning and North American P-51 Mustang fighters, however this is coincidental.They are also still seen in disaster recovery efforts and have been handed out alongside canned food by rescue organizations, both in America and abroad in Afghanistan.A non-folding version of the P-38 used to be very common in Israeli kitchens, and can still be found in stores, often sold in packs of five.Electric openers were re-introduced in 1956 by two Californian companies.Lid still on can.http://www.drupalitalia.org/node/70877 Whereas most other openers remove the lid by cutting down through the lid from the top just inside the rim, removing the top and leaving the rim attached to the can, these use a roller and cutting wheel to cut round the side of the can just below the rim, removing the top and rim. The can is left with a relatively safe, non-jagged edge, and the top can be set back on top as a cover, although it does not provide a seal.Retrieved 8 August 2009. Retrieved 8 April 2015.

The basic parts hold the can steady—whether by hand or with a mounted or built-in base--and cut the can open, which makes accessing the contents of metal cans much easier. The first can opener, which punctured the can's metal top, was designed in 1858. The device we all know today with a round knife was invented in 1870 and allows for a continuously smooth edge on the lid; nearly 60 years later, the first electric can opener was invented. In mounted can openers, usually screwed into a countertop or wall-mounted, the base keeps the can steady and, in electric can openers, the built-in base helps maintain can position during opening. Some wall- and counter-mounted can openers have an adjustable crank shaft to accommodate different sized cans. The gear is connected to an electric crank or by a manual crank, which is maneuvered by the operator.

Santo 5.0 out of 5 stars I didn't think I could be so excited over a can opener, but seriously it's been the best can opener I've ever owned - electric and manual. Like the product description states, I really felt like it ripped through my can of coconut milk like butter. From my experience, the canned items I get from the Asian market seems to be a thicker metal material and my previous can opener would struggle to even make the first puncture. Once that happened, it would never make a straight cut and I'd end up seeing shreds of paper from the label on my counter top and the raised lips along the lid would show the amount of struggle it took just get it off. Not sure on the longevity of it, but take a chance on this product, it really works as stated.The first time I tried to use it, it locked up after cutting about one inch of a can, and I ended up with the opener in one hand and the loose turning knob in the other - it snapped right off. I'm not a very strong person - in my 70's and only marginally fit, and it didn't feel to me like I was squeezing or turning any harder than I did with the old can opener (which is a bit dull and hard to use, thus the new one). It took me a while to figure out what happened. There are two gears that mesh when the handle is closed, so the blade and the can guide both turn. Instead of meshing when I went to cut the can, the two gears sat with the tips of two teeth of each gear touching, and just stayed that way. When I squeezed to cut the blade into the can, the gears stayed on the tips of the teeth and still didn't mesh. Instead, the two lower teeth bent as the blade cut into the can.www.cir.cloud/wp-content/plugins/formcraft/file-upload/server/content/files/1626faa0287374---bose-awr1-1w-user-manual.pdf When I started to turn the knob, all was well for the first inch or so around the can, but when the bent teeth got back to the other gear it stopped solidly and the knob snapped off. I tried the old can opener to see if I could balance the gears on two teeth so they wouldn't mesh. I could, a little, but if I started to squeeze they always slipped off and meshed. With this opener, once the tooth tips locked together they would not slip off. The handle has to be opened and the gear turned manually to a place where it will mesh, or the teeth get bent. These need to be manufactured with the gear teeth shaped properly so they can't lock, and made of a stronger material so they don't get damaged so easily. The knob is thin plastic where it attaches to the shaft, and it broke easily. I filled the center of the knob with hot glue and pushed it back on, making it much stronger than it was originally, and straightened the teeth out as well as I could, but they were partly broken. I got finished with my 4 cans, but it still bound a few times. My partner tried it, but the first time it bound it hurt her wrist enough that she refuses to try it again. So now it's just a piece of worthless scrap metal. Oh, and I saw another problem while working on it. The blade was nicked up, and I discovered that when closing the handle to put it away, the blade doesn't always go next to the can guide wheel, sometimes it hits it. That's not a situation where it would get squeezed that way - just shake it a little and close it again. But it must have been happening fairly often, because the blade looked nicked all around. The mechanism should be built with enough precision that the blade doesn't hit the other parts.She has arthritic hands. She had no problems using the can opener. The can opener is built very sturdy and is very easy to use. Definitely would recommend for people with wrist problems or arthritis.Is very smooth and easy to turn.www.cpfledlighting.com/userfiles/file/car-maintenance-pdf I have had trouble with openers in the past, but this one works like a charm. I wish i had gotten one a long time ago!The handles are rounded so it is comfortable to hold but also enables you to apply more grip pressure as needed. The blade is sharp and the magnet really helps to get that lid out of the can without spilling contents.Sturdy and so far very good.I've used it 3 times now, and it opens cans with ease. The 1st time using it, was a little rough, but once it gets broken in, it works perfectly. It cuts the cans and leaves no rough edges. I just hope it lasts for awhile, because it's so hard to find a good can opener that actually lasts these days.Blade rolls smoothly over the lid with no slippage. Grip design is easy to hold. Ease of use for arthritic persons is more problematic, as gripping pressure needed is more challenging. For a woman with arthritis, the grip may be too big and heavy. Great for those not yet needing an electric opener.In order to navigate out of this carousel please use your heading shortcut key to navigate to the next or previous heading.

Tina 4.0 out of 5 stars I thought it would open the can a lot smoother. You need to use a little umph turning the handle.The can opener itself Works real well I am very pleased with my purchase. And by the way this is my first how to video ever for a product I purchased through AmazonNothing is more irrating than to realize your can opener does not work properly. This can opener does not disappoint. And it is much more convenient than other ones.I completely recommend purchasing this item!It actually opens dog food cans. I had so much trouble with other brands opening the cans I had to toss them in frustration. It's so far so good since my first purchase in October.The extra blades are a nice bonus!It's easy to turn the handle and I don't have to struggle using it. It seems durable and I think if it was going to break, it would've broke by now. I luv the bright color!!I'm not sure why it's so hard to make a good can opener, but I've not had a good one for many years. The gears clearly don't line up so I need to turn the handle much more than I should to get it to move along the edge of the can. The gears slip and it's very frustrating. Don't waste your money on this one. Ill try to attach a photo to show that the gears are out of alignment. I never forced this can opener and I never expected anymore more from it. It just doesn't do it's primary function. If I still had the box, I'd return it.And this can opener is worse than the ancient one I had when I was eighteen living in a house of first year students. First time I used it, the teeth didn't catch on the metal, it took a lot of effort to get the cutter around the whole can. Third time I used it, I can already feel it giving and falling to pieces. It's just frustrating and difficult to use.It really easy to use and opens the cans really easily. It is really sharp and seems durable and great quality. It also comes with extra blade. Great addition to my kitchen. Definitely a life saver.After 4 months of minimal use it is basically garbage. It is made of very cheap, overly malleable metal that has already started rusting. Avoid the headache, buy a different can opener.The handles are so flimsy they are constantly bending. It takes two hands to pry it open to remove it from the can. The spare gears are provided because they will fail after a very short time. I have had this 3 months and it is now garbage.In order to navigate out of this carousel please use your heading shortcut key to navigate to the next or previous heading.Call 1300 60 60 24. We have 8 tips to help you avoid injury. And 147 workers were killed at work. Never lift more than what you can manage safely. It may be that the work can be completed somewhere else to avoid lifting the item over a distance. Or there may be lifting aids to help them complete the task mechanically. Perhaps someone else could help too. If this isn't possible, consider re-arranging the task to minimise the risk. Employees may be able to push instead of pull or break up the distance with more rest points. Can it be made more stable, or easier to grasp. Should circular or irregular-shaped items be packed into boxes instead to prevent rolling? Check the walkway - are there uneven surfaces, gradients or blind corners. Avoid steps, ramps, twists and turns. Consider whether the lighting needs to be improved and what personal protective equipment to use. Before starting, employees should decide exactly what will be done and how. It might help to have someone walking in front or behind to warn others and watch out for hazards. Plans need to be communicated to others too, including colleagues who work in the vicinity. Pinpoint the optimum time for lifting - perhaps when the area is quieter. For example, by using real work-related scenarios specific to your company. This will help keep staff engaged and help to embed the right behaviours and practices. But it should also cover a diverse range of areas. Depending on the individual employee’s role, training may cover everything from manual handling, to managing work-related stress and dealing with violence and aggression. With this in mind, it’s also important to have checklists visible to all staff to serve as a reminder. We are happy to help!

Failure to ensure the health and safety of employees when working with large or heavy loads can lead to serious injury and may come at a great cost to your business. This includes lifting, putting down, pushing, pulling, carrying, maneuvring or transporting. Our Health and Safety in the Workplace booklet provides advice on the subject, together with several other health and safety common issues that everyone should be aware of. However, these can also present their own additional risks. A minor issue or concern identified may receive informal advice whereas more serious issues (for example a lack of manual handling risk assessment) could result in enforcement action being taken. If an officer believes that there has been a material breach of health and safety regulations, an improvement notice may be issued. If this breach presents a risk of serious injury, then a prohibition notice may be provided which stops the activity from being conducted until the problem has been resolved. It is estimated that 21 of all non-fatal workplace injuries are attributable to manual handling injuries and that one-third (some 156,000) of musculoskeletal disorder injuries are also caused through manual handling activities. These are a combination of the load, the task, the environment and the individual. A manual handling risk assessment may also be required at this stage. The HSE has provided guidance on reasonable weight limits based on the lifting ability of an average fit male or female (see the below image). Situational factors to consider are the strength, fitness, and underlying medical conditions the person might have. Then weight to be lifted and distance to be carried, the nature of the load, the postures to be adopted and the availability of equipment to facilitate the lift. However, this can present additional problems including obscured vision during the activity and uneven distribution of weight and content. In such cases, the operation of the equipment must be conducted by a competent person in a safe manner.
