Points for attention in the use and maintenance of brush cutters

Posted by sere on November 30th, 2020

Brush cutters, also known as grass brush cutter, is divided into electric power and internal combustion power through different powers. Internal combustion power is divided into two-stroke and four-stroke gasoline engines. Through different transmission methods, it is divided into flexible shaft transmission and straight rod transmission. It has a wide range of uses, which mainly used for landscaping, garden maintenance, road cleaning, forest fire prevention, crop harvesting, etc.

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

1. Engine

The engine is a two-stroke engine. 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, and the engine oil should be two-stroke engine oil. The symbol is 2T. You must use brand-name engine oil, preferably 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. It is firmly not allowed to 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 dispense oil as estimated. The mixed oil is best prepared for immediate use, and it is strictly forbidden 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 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 the muffler outlet.

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

2. Transmission part

Replenish the gearbox (working head) with grease every 25 hours, and at the same time fill the joint between the upper part of the drive shaft and the clutch disc with grease.

3.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.

4.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.

5.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.
