Gasoline saw use method
One, gasoline saws is two stroke power, use from power, transmission and tool three aspects of attention, it can ensure the normal use of the machine:
In 1, the engine:
A, qualified gasoline and oil, ensure its mixing ratio ( 25: 1);
B ( 25 hours ), regular inspection and replacement of air filter check spark plug;
C, a box of oil, should rest 10 minutes, after each operation cleaning machine for gasket, guarantee the heat dissipation;
D, storage, must clear off the body, fuel mixture, carburetor fuel burning clean; remove the spark plug, cylinder to join 1-2ml two stroke engine oil, pull starter 2-3, fitted with spark plug.
In 2, the transmission: regular (25 hours ) to replenish the lubrication grease
In 3, the tool: regular (25 hours ) to check on blade clearance, and the timely adjustment of ( interval for bolt semi thread interval), to maintain a sharp edge. For each hour of work to the filling, pruning diameter ' = 10mm.
In two, minus 30 degrees C using chain saw having those matters needing attention?
In 1, recommendations fuel mixing ratio 20: 1 to 15: 1 ( must use high quality air cooled two stroke oil mixed ), saw chain lubricating oil should be added in 10% ~ 30% diesel ( oil or oil ) were mixed before use, to ensure proper concentration. Its proportion should be based on the saw chain squirting oil quantity and decided to join the degree, but should control in 10% ~ 30% range.
2, idling speed should be adjusted as: 2500 ~ 3000 rpm, and the room temperature when the idle speed is 2000 rpm.
Three, two stroke mechanical fuel mixture ratio?
General two stroke mechanical fuel with turbine oil blend ( including oil for two stroke engine oil ), ratio criterion, steam oil ratio of about 25 to about 1, ( I suggest 20: 1) as the use of circumstances, if the use is not a long time high speed operation, may be appropriate to improve concentration, if use often keep a high-speed rotation, should be appropriate to reduce the concentration of, put some more oil, ensure that the cylinder internal moving parts of the normal lubrication, but attention should be given to remove the muffler, removal of exhaust passage in coke, so as to avoid excess carbon deposit into the cylinder, causing scuffing.
