Guide to the correct use and maintenance of lever action grease guns

In the field of industrial and mechanical equipment maintenance, lubrication is one of the key steps to ensure smooth operation of equipment and extend its service life. Among them, lever action grease guns, as an efficient and convenient lubrication tool, are widely used in grease filling operations for various bearings, sliding surfaces and rotating parts. However, to give full play to its effectiveness and ensure operational safety, correct use methods and meticulous maintenance are indispensable. This article will discuss in detail the inspection preparation, operation skills and maintenance precautions of lever action grease guns before and after use, aiming to provide operators with a comprehensive and practical guide.

1. Inspection and preparation before use

1. Component integrity inspection

Before using a lever action grease gun, the first task is to conduct a comprehensive component inspection. This includes but is not limited to checking whether the gun body has cracks, deformation or wear, whether the piston rod is smooth and free of rust, whether the handle is firm and not loose, and whether each connection part (such as the connection between the gun nozzle and the gun body, and the connection between the piston rod and the handle) is tight and leak-free. Any slight damage or looseness may affect the normal operation of the grease gun, and even cause failures or safety accidents, so it must be inspected in detail.

2. Butter preparation

Choosing the right butter is crucial for lubrication. According to the equipment's use environment, operating temperature and lubrication requirements, choose butter with appropriate viscosity, antioxidant properties and extreme pressure properties. At the same time, ensure that the butter is clean and uncontaminated to avoid mixing impurities that affect the lubrication effect or damage the equipment.

2. Tips for filling butter

1. Control the pressure and speed

When filling butter, the force and speed of the operating handle should be moderate. Excessive pressure or too fast operation may cause excessive injection of butter, which not only wastes materials, but also may cause abnormal pressure inside the equipment and affect normal operation. On the contrary, insufficient pressure or too slow speed may cause insufficient injection of butter and poor lubrication effect. Therefore, the operator needs to flexibly adjust the pressure and speed according to the lubrication requirements of the equipment and the performance of the grease gun.

2. Observe the overflow of butter

During the filling process, it is very important to closely observe the overflow of butter from the lubrication part. When the butter overflows evenly around the lubrication point, it indicates that the part is fully lubricated. At this time, the filling should be stopped in time to avoid waste or pollution caused by excessive lubrication. If the butter does not overflow smoothly or there is no obvious overflow, it may mean that the lubrication channel is blocked or the filling position is incorrect, and it needs to be checked and adjusted in time.

III. Cleaning and maintenance after use

1. Cleaning the grease gun

After use, cleaning the lever grease gun immediately is the key to preventing blockage and corrosion. Use a special cleaning agent or solvent to thoroughly clean the remaining butter inside the gun body, especially the piston rod, gun nozzle and other parts that are prone to blockage. The outside should also be wiped clean to remove oil and dust. After cleaning, the grease gun should be dried to avoid rust caused by residual moisture.

2. Storage and preservation

After cleaning and drying, the lever grease gun should be stored in a dry and ventilated place, away from humid environments and corrosive substances. Avoid direct sunlight to prevent material aging. At the same time, it is recommended to conduct secondary inspections and maintenance of the grease gun regularly (such as every quarter or half a year), including lubricating moving parts, checking sealing, etc., to ensure that it is always in good condition.
