Use and maintenance of irrigation machines

The cutting machine is a two-stroke power system, and attention should be paid to power, transmission, and cutting tools during use to ensure the normal use of the machine.

engine

The engine is a two-stroke engine, using a mixture of gasoline and engine oil. The ratio of the mixture oil is: two-stroke special engine oil: gasoline=1:50. Gasoline should be grade 90 or above, and engine oil should be two-stroke engine oil with the symbol 2T. It is necessary to use branded engine oil, preferably specialized engine oil, and the use of four stroke engine oil is strictly prohibited. It is recommended to mix 1:40 oil for the first 30 hours of the new machine, and then mix 1:50 oil according to the normal ratio after 30 hours. It is strictly not allowed to exceed 1:50, otherwise the concentration is too thin and may cause the machine to pull the cylinder. Please strictly follow the oil dispenser provided with the machine to dispense oil, and do not dispense oil arbitrarily according to estimates. It is best to prepare and use mixed oil on site, and it is strictly prohibited to use mixed oil that has been prepared for a long time;

Before starting the machine, run it at low speed for a few minutes before starting. When the machine is working, just use the high speed throttle normally. After working on a box of oil, take a 10 minute break and clean the loose gasket of the machine to ensure heat dissipation;

◆ Spark plugs should be removed every 25 hours of use. Use a steel wire brush to remove dust and dirt from the electrodes, and adjust the electrode gap to 0.6-0.7mm;

The air filter should remove dust every 25 hours of use, and dust should be removed more frequently. The foam filter element shall be cleaned with gasoline or detergent and clean water, squeezed and dried, soaked with engine oil, and then squeezed to remove excess engine oil for installation. If it is printed with "DON NOT OIL", there is no need to add oil;

◆ After using the muffler for every 50 hours, remove the muffler and clean the carbon deposits on the exhaust port and muffler outlet.

The fuel filter (suction head) removes impurities every 25 hours.

Transmission part

Add lubricating grease to the gearbox (working head) every 25 hours, and also add lubricating grease to the joint between the upper part of the transmission shaft and the clutch disc.

Tool section

Nylon cable heads should be controlled in length, not exceeding 15 centimeters. The blade must be installed correctly and balanced.

Use Safety

Before homework, no one or animals are allowed to walk within 20 meters of the surroundings. Be sure to check for angle iron, stones, and other debris on the grass, and remove any debris from the grass.

Storage

When storing, the body must be cleaned, the mixed fuel must be discharged, and the fuel in the vaporizer must be burned clean; 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.
