2. The gasoline engine should be started with no load, the throttle should be minimized, and the new gasoline engine should have a running-in period. When the gasoline engine speed reaches 1500 ~ 2000 rpm or more, the clutch can be engaged.
3. Gasoline engine fuel must be prepared in strict accordance with the volume ratio of gasoline to engine oil of 20: 1. The fuel volume ratio is 15: 1 within 5 hours after the new gasoline engine is put into use.
4. It is forbidden to operate without air filter because of the big wind and sand in the field.
5. The feed speed of the grinding wheel of this machine should be moderate at a time, generally 0.05 ~ 0.2 mm, which should match the walking speed. When the feed speed is high, the walking speed should be slowed down accordingly. 1. The speed of the gasoline engine has been adjusted at the factory, and the positions of the speed limiter and the spring cannot be changed at will. If the maintenance changes the position, it must be re-checked.
2. The speed control chamber of gasoline engine is lubricated by flying grease, and the oil level in the speed control chamber must be checked every 50h (the machine must be put down so that the cylinder is in an upright position of 10 ~ 15 min, and then the lubricating oil completely flows back to the oil pan of the speed control chamber, and then the oil dipstick is rotated for inspection.
3. After long-term use, the oil seal at the output shaft end of gasoline engine will leak out of the speed control chamber due to poor sealing, and should be replaced after 500h use.
4. The vertical and horizontal screws of the grinder should be lubricated with oil.
