Snap-on (NYSE: SNA) is a leading U.S. designer, manufacturer and marketer of tools and equipment to professional tool users. It was founded in 1920. Snap-on is located in Kenosha, Wisconsin, and employs thousands of people worldwide. Snap-on also made an appearance in the movie Swordfish as well as other key television shows, such as American Chopper. In 1999 it acquired the Swedish tool-maker Bahco. History The modern socket wrench, with interchangeable sockets, was invented by an American J.J. Richardson, of Woodstock, Vermont. The tool was patented through the Scientific American Patent Agency on June 18, 1863. The first illustration of the tool appears on pg. 248 of the April 16, 1864 issue of Scientific American. Pioneering the idea of interchangeable sockets and wrench handles, Joseph Johnson and William Seidemann formed the Snap-on Wrench Company in 1920. The company manufactured and marketed ten sockets that would "snap on" to five interchangeable handles, a concept t...

An internal combustion engine is an engine that is powered by the expansion of hot combustion products of fuel directly acting within an engine. A piston internal combustion engine works by burning hydrocarbon or hydrogen fuel that presses on a piston; and a jet engine works as the hot combustion products press on the interior parts of the nozzle and combustion chamber, directly accelerating the engine forwards. By way of contrast, an external combustion engine such as a steam engine, does work when the combustion process heats a separate working fluid, such as water or steam, which then in turn does work. Jet engines, rockets and gas turbines are classed as internal combustion engines, but the term "internal combustion engine" is often loosely and incorrectly used to refer to piston internal combustion engine in which combustion is intermittent and the products act on reciprocating machinery, the most common subtype of this kind of engine. Operation All internal combustion e...

The two-stroke cycle of an internal combustion engine differs from common four-stroke cycle by having only two strokes (linear movements of the piston) instead of four, although the same four operations (intake, compression, power, exhaust) still occur. Thus, there is a power stroke per piston for every engine revolution, instead of every second revolution. Two-stroke engines are used most among the smallest and largest reciprocating powerplants, but less commonly among medium sized ones. The smallest gasoline engines are usually two-strokes. They are commonly used in outboard motors, high-performance, small-capacity motorcycles, mopeds, scooters, karting, model airplane and motorized garden equipment like chainsaws and lawnmowers. In each application, they are popular because of their simple design (and consequent low cost) and very high power-to-weight ratios (because the engine has twice as many combustions per second as a four stroke engine revolving at the same speed). For handhel...

Preventive maintenance has the following meanings: The care and servicing by personnel for the purpose of maintaining equipment in satisfactory operating condition by providing for systematic inspection, detection, and correction of incipient failures either before they occur or before they develop into major defects. Maintenance, including tests, measurements, adjustments, and parts replacement, performed specifically to prevent faults from occurring. Preventive maintenance can be described as maintenance of tools and equipment before fault occurs. It can be divided into two subgroups: Planned maintenance and condition-based maintenance. The main difference of subgroups is determination of maintenance time, or determination of moment when maintenance should be performed. While preventive maintenance is generally considered to be worthwhile, there are risks such as equipment failure or human error involved when performing preventive maintenance, just as in any maintenance operation. Pr...

Determining the best chainsaw chain depends on the specific needs of the user and the type of cutting tasks they intend to perform. Chainsaw chains come in different styles, sizes, and materials, each designed for specific applications. The following are common types of chainsaw chain. Full Chisel Chain A full chisel chain is a type of chainsaw chain that is characterized by square-cornered teeth. These chains are designed for aggressive cutting in demanding situations, making them well-suited for tasks that require high cutting speeds through hard or dense wood. Full chisel chains are known for their aggressive cutting performance. The square-cornered teeth bite deeply into wood, making them effective for tasks that require a high level of cutting speed and efficiency.  Due to the design of the teeth, full chisel chains tend to have a faster cutting speed compared to other types of chains. This makes them suitable for professional logging, felling large trees, and other heavy-duty...

Oil change steps Change the engine oil with the engine warm and in a horizontal position to assure complete and rapid draining. 1) Remove the oil filter cap, dipstick and drain bolt. Allow the oil to drain completely. 2) Reinstall the drain bolt and tighten it to specified torque (23 Nm, 17 ft-lb) 3) Fill the crankcase with the recommended engine oil to the outer edge of the oil filler neck. Reinstall the filler cap and dipstick. Honda GX240K1, GX270, GX340K1 and GX390K1 oil capacity = 1.1 liter (1.16 U.S. qt, 0.97 Imp. qt) Honda engine oil recommendations Use Honda 4-stroke oil or an equivalent high-detergent premium quality motor oil certified to meet or exceed U.S. automotive manufacturer's requirements for Service Classification SG.SF/CC.CD. Motor oils classified SG.SF/CC.CD. will show this designation on the container. SAE 10W-30 is recommended for general all temperature use.

Purchase only the amount of fuel that will be used in 30 days. Fuel deteriorates over time. Deterioration begins with the most volatile compounds evaporating. Once evaporation reaches a certain point it will be hard or impossible to start the machine. As more compounds evaporate, the fuel will form brown gummy deposits in the system. Given enough time the gummy deposits will become a hard varnish. Gummy deposits and varnish can plug passages in the carburetor preventing the engine from running or causing the engine to run poorly (surging, lack of power, stalls, etc.). Deposits can also cause the carburetor to leak fuel if they prevent the float needle from sealing properly. Add fuel stabilizer to the fuel the day you buy it. Most fuel stabilizers form a layer over the top of the gasoline and greatly reduce the rate the fuel’s volatile compounds evaporate. They also prevent the absorption of moisture by the fuel. If fuel stabilizer is added to gasoline the day the gasoline is purchased,...

Anytime a carburetor is replaced, it might need some preliminary adjustments. New replacement carburetors are often shipped with the plastic limiter caps not permanently seated. Only after the final adjustments are made to the carburetor should the limiter caps be pushed down over the serrated part of the adjustment needle. After a new replacement carburetor in installed and before any adjustments are made, start and run the equipment until it is at its full operating temperature (around 4 or 5 minutes). If the equipment will not start, back out the idle screw slowly until you can see a gap between the lever and the screw. Then turn the screw back in slowly until it touches but does not move the lever. Now turn the screw in 1/2 to 3/4 turn more to move the lever (which will open the throttle valve slightly). Next remove the limiter caps by gently pulling up on them with needle nose pliers. Now close both adjustment  needles very slowly clockwise, until each gently bears against its...

All adjustments should be checked at least once each season. Always observe the safety rules when performing any  maintenance. BEFORE EACH USE 1. Check engine oil level. 2. Check for loose fasteners. 3. Check controls to be sure they are functioning properly. AFTER EACH USE Clean and inspect the snow blower Do not use a garden hose to clean your snow blower unless the electrical system, muffler and carburetor are covered to keep water out. Water in engine can result in shortened engine life. For best performance, keep snow blower housing free of any dirt or trash. Clean the outside of your snow blower after each use. • Once a year, you should replace the spark plug, change engine oil and check belts for wear. A new spark plug will help your engine run better and last longer. TIRES • Maintain proper air pressure in both tires  • Keep tires free of gasoline and oil, which can harm rubber. NOTE: To seal tire punctures and prevent flat tires due to slow leaks, tire sealant may be ...
