Hand-held Power Tool Safety Technology

Hand-held power tools are divided into I, II, III class in accordance with security requirements.
Class I hand-held power tools rated voltage exceeds 50V, is non-secure voltage, It must be ground or zero for protection, but also must be connected leakage protection to ensure safety.
Class II hand-held power tools rated voltage exceeds 50V, but it uses double or reinforced insulation additional security measures. Double insulation means that  in addition to insulation work, as well as a protective insulating layer. When damage the insulation, operator isolate to charged body, it will not shock.
Class III hand-held power tools use safe voltage, it needs to have a good two-winding transformer isolated power supply, transformer rated voltage does not exceed 50V. So they is not necessary to connect ground, but be sure to install leakage protection.
Hand-held power tools must be installed isolation switch, short circuit protection, overload protection or leakage protection.

What Is The Hand Rivets?

Hand rivet is used of riveting one side of the workpiece. Usually dedicated to the blind rivet. Hand rivet is used for fastening riveted various types of sheet metal, pipes and other manufacturing industries.
Hand rivet is now widely used in the automotive, aviation, railway, refrigeration, elevators, switches, instruments, furniture, decoration and other mechanical and electrical products. To solve the sheet metal, thin tube welding fusible nut, it can be riveted, riveting has high efficiency solid, easy to use.
There are many types of hand rivet, hand rivet is divided into electric, manual and pneumatic according to the power type, manual rivet is the most widely used, easy to operate, with the appropriate tools, such as electric hand drill, impact drill and others to use.

Chain Saw Maintenance

Chain saw maintenance, the most important is that the saw chain. Proper maintenance and sharpening the saw chain saw only a small pressure can be easily into the wood. When routine maintenance, pay attention to check whether there are cracks and broken rivets, replace any damaged or worn parts on the chain saw, then  match with new parts with the same shape and size as the original one.
If the filter of the chain saw is stuck by dirt, you need special filter to clean, and dry. Do not use a brush to clean wool filter.
Note that, even if the regulations require the use and maintenance of the chain saw, some parts of the power tool will have normal wear and tear, and therefore must be based on the model and use of parts and promptly replaced. These components include: chain, guide plate, transmission parts (clutch, clutch drum sprocket), filters, starter, spark plugs and shock absorber system parts.

How to Gasoline Chainsaw?

Gasoline chainsaw is one of many garden products, it has the most wide range and the highest frequency of use. Because it comes with sharp sawtooth for high-speed cutting of wood. Therefore, when using it, we need to take more stringent safety precautions. Any non-standard operations, not timely maintenance, will form a certain security risk, we need to pay attention.
First of all, when you start the chainsaw, do not start hove to end. Gently pull the starting handle until the stop position, then quickly pulling force, while pressing down the front handle.
Next, after the long-time operation of the engine at maximum throttle, let it idle period, so that flow of cooling air, release most of the heat in engine.
Again, if the engine power is decreased, it may be caused by dirty air filter. Remove the carburetor cover and remove the air filter, clear dirt around the filter.

Garden Tools Cutting Tips

In the cutting operation, for garden tools, it is more complex to fell trees or cut large diameter trunk. When felling trees, first, clear branches and leaves in the tree roots work area, clean out the foundation of the work area of the tree, in order to find a secure foothold. Then cut tree grooves with a hand saw, first longitudinally then laterally cut the tree at the selected foundation, can make use of the chain saw housing cover analyzer to determine fallen direction of the tree, fallen direction of the tree is vertical to tree groove, the groove should be as close to the ground, cutting depth of about 1/5 to 1/3 the diameter of the trunk.
