What are the key points for the use and maintenance of brush cutter? Posted by : admin / Posted on : Jan 25,2021

The brush cutter is a two-stroke power, and attention should be paid to power, transmission and cutting tools during use to ensure the normal use of the machine.
1. Engine
The engine is a two-stroke engine, and the fuel used is a mixture of gasoline and engine oil. The ratio of the mixed oil is: two-stroke special engine oil: gasoline=1:50. The gasoline should be above No. 90, the engine oil should be two-stroke engine oil, the symbol is 2T, you must use brand-name engine oil, it is best to use special engine oil, four-stroke engine oil is strictly prohibited. It is recommended that the new machine be equipped with 1:40 in the first 30 hours and the normal ratio of 1:50 after 30 hours. Do not exceed 1:50, otherwise the concentration will be too thin and the machine will pull the cylinder. Please dispense oil strictly according to the oil dispenser attached to the machine, not arbitrarily according to estimates. The mixed oil is best prepared for immediate use, and it is strictly prohibited to use the mixed oil that has been stored for a long time;
Before the machine works, run it at low speed for a few minutes before working. When the machine is working, use the high speed throttle normally. After each tank of oil work, you should rest for 10 minutes, and clean the loose gasket of the machine after each work to ensure heat dissipation;
The spark plug should be removed every 25 hours of use, and the dust on the electrode should be brushed with a wire, and the electrode gap should be adjusted to 0.6-0.7mm;
The air filter removes dust every 25 hours of use, and the dust should be more frequent. The foam filter element is cleaned with gasoline or washing liquid and clean water, squeezed to dry, and then soaked in oil, squeezed out the excess oil to install. If it is printed with "DON NOT OIL", there is no need to add oil;
Every 50 hours of use of the muffler, remove the muffler and clean up the carbon deposits on the exhaust port and muffler outlet.
The fuel filter (suction head) removes impurities every 25 hours.
2. Transmission part
Replenish grease to the gearbox (working head) every 25 hours, and at the same time refill the joint between the upper part of the drive shaft and the clutch disc.
Third, the tool part
The length of the nylon cable head should be controlled, not more than 15 cm. The blade must be installed upright and balanced.
Fourth, use safety
Before operation, no people or animals are allowed to move within 20 meters. Be sure to check whether there are angle irons, stones and other debris on the grass, and remove the debris on the grass.
Five, storage
When storing, you must clean the body, drain the mixed fuel, and burn the fuel in the vaporizer; remove the spark plug, add 1-2ml of two-stroke engine oil to the cylinder, pull the starter 2-3 times, and install the spark plug.
