A, definitions,

Chain saw is also called the chain saw, hand saw powered by gasoline engine, it is mainly used for logging and building material, its working principle is to rely on interlaced L saw chain blade lateral movement for shear action

Second, the species

Chain saw is a kind of broken device, which can be divided into motor chain saw, non-motor chain saw, concrete chain saw, etc.

Three, notice the matter

Always check the chain tension, turn off the engine when checking and adjust, and wear protective gloves. A good condition is that when the chain is attached to the bottom of the guide plate, the chain can be pulled by hand.

There must always be a little oil in the chain. Every time before work, you must check the oil in the chain lubrication and lubricating oil tank. No lubrication in the chain, such as working in a dry chain, can cause damage to the cutting device.

Never use old oil. The old engine oil is not suitable for lubrication, not for chain lubrication.

If the oil in the tank does not decrease, it may be a failure of lubrication. Should inspect chain lubrication, check oil road. A contaminated filter can also cause bad oil supplies. Clean or replace lubricating oil filters in tanks and pumps.

After replacing the new chain, the chain needs two to three minutes of grinding time. After the mill is closed, check the chain tension and adjust it as necessary. The new chain needs to be tightened more often than the chain that has been used for a while. The chain must be attached to the bottom of the guide when cold, but the chain can be moved by hand. If necessary, tighten the chain again. At operating temperature, saw chain expansion slightly pendulous, transmission section at the bottom of the guide can't emerge from the chain slot, change jobs, or the chain will need to reopen the tension chain.

The chain must be relaxed after work. The chain will contract when it cools, and no loose chain will damage the crankshaft and bearing. If the chain is tight at work, the chain contracts when it is cooled and the chain is too tight to damage the crankshaft and bearing.

The use of oil products

Chain saw needs to use petrol, engine oil and chain saws.

Gasoline can only be used for unleaded gasoline above 90. When adding gasoline, the cap and filler must be cleaned before refueling, so there is no debris entering the tank. The high branch saw should be placed in a flat place to cover the top of the tank. Don't let the petrol spill out of the tank, and you can't fill it up too much. Always use your hand to tighten the lid of the tank.

The engine oil can only use the high quality two-stroke engine oil to ensure that the engine has longer service life, and do not use the ordinary four-stroke engine. When using the other two stroke engine oil, its model should reach the tc grade quality. Poor quality of gasoline or oil can damage engines, seals, oil lines and tanks.

The mixture proportion of gasoline and oil is 1:50, that is, 1 oil and 50 gasoline. Use other engine oil that conforms to tc level 1:25, which is 1 oil and 25 gasoline. The hybrid approach is to put the oil in a fuel tank that allows the fuel to be filled, then fill it with gasoline and mix well. The gasoline mixture will age, and the general configuration will not exceed one month's use. It is important to avoid direct contact with the skin and avoid the gas that evaporates from the gas.

Use high quality chain saw chain lubricating oil to keep lubricants not below the oil level to reduce the wear and tear of chain and serrated. Due to the chain saw lubricating oil will completely discharge into the environment, ordinary lubricating oil is a petroleum base, non-biodegradable, will pollute the environment, suggest to use biodegradable environmental protection oil chain saw, many developed countries have a hard and fast rules about this matter to avoid the pollution of the environment.

The selection basis of the saw bladeClassification of material attributes according to sawingReal wood: cut and cut vertically.Crosscutting need to cut the wood fibre, aspect demand level off, can't have a knife, and there can be no burr, the saw blade used in the outer diameter of 10 or 12 inches and teeth should be 60 to 120 tooth, the thinner material using the more teeth machine accordingly. Feed speed also need to be slow. The number of teeth on the slitting saws is relatively small, feeding speed will be faster, so very tall to the requirement of chip removal, so the requirements of ...
