A hedge trimmer to use the note
The hedge trimmer is a two-stroke power should power transmission and tool attention to three aspects, to ensure the normal use of the machine:
1, engine:
A qualified gasoline and oil to ensure that the mixing ratio (25:1);
B, on a regular basis (25 hours) check and replace the air filter to check the spark plug;
C, and a box of oil per work should rest for 10 minutes to clean the machine after each work loose gaskets ensure heat dissipation;
D, storage, you must clean up the body, let go of the mixed fuel, burning fuel in the carburetor net; remove the spark plug, adding 1-2ml two-stroke engine oil to the cylinder and pull the starter 2-3 times, fitted with a spark plug.
Transmission: add grease on a regular basis (25 hours)
3, the tool: (25 hours) on a regular basis to check the upper and lower edge of the gap, and timely adjustment of the semi-circle thread interval (interval bolts), keep a sharp edge. Per hour of work filling the oil to the blade, trim diameter <= 10mm.
Second, the use of brush cutters should pay attention to?
Two-stroke brush cutter power should power use and tool to pay attention to three aspects, to ensure the normal use of the machine:
1, engine:
A qualified gasoline and oil to ensure that the mixing ratio (25:1);
B, on a regular basis (25 hours) check and replace the air filter to check the spark plug;
C, and a box of oil per work should rest for 10 minutes to clean the machine after each work loose gaskets ensure heat dissipation;
D, storage, you must clean up the body, let go of the mixed fuel, burning fuel in the carburetor net; remove the spark plug, adding 1-2ml two-stroke engine oil to the cylinder and pull the starter 2-3 times, fitted with a spark plug.
Transmission: on a regular basis (25 hours) to the gear box to add grease lubrication to the junction of the drive shaft upper clutch disc.
Tool: nylon cable head should control its length <= 15cm, knife films, should ensure the balance of the blade, do not use the blade vibration.
Third, in minus 30 ℃ oil saw those considerations?
First, the proposed fuel mixing ratio of 20:1 to 15:1 (with the quality of the air-cooled two-stroke oil must be mixed), the saw chain within the lubricating oil should be added to the 10% to 30% of diesel (kerosene or light oil, ) mixed before use, to ensure that the appropriate concentration. Its proportion of the saw chain spray oil and to decide to join, but lies in the range of 10% to 30%.
, Idle speed should be adjusted as follows: from 2500 to 3000 rev / min, and at room temperature when idle speed of 2000 rev / min.
Four, two-stroke mechanical fuel ratio?
General two-stroke machinery fuel oil steam mixture (including oil for two-stroke engine oil), the ratio standard steam oil ratio is about 25:1 or so, depending on usage, if the use is not a long time high-speed operation, may be appropriate to improve concentration, use often maintain high-speed dynamic change, will have to be appropriate to reduce the concentration, put some more oil, ensure the normal lubrication of the moving parts of the interior of the cylinder, but attention should be given to remove the muffler, clear exhaust Road coke, in order to avoid too much coke into the cylinder, causing the pull cylinder.
