Precautions and maintenance of grease gun

Precautions and maintenance of grease gun
1. Before use, check whether the valve spring, steel ball and other parts are in short supply, the sealing condition of piston and oil gun head, and pay attention to check the squeezing effect to ensure the smooth maintenance.
2. If the running equipment is checked and filled with oil, it shall be marked with stop operation.
3. During oil injection, the oil nozzle at the front of the oil injection rod shall be aligned with the grease nozzle, and the inclination shall not be greater than 8 °.
4. When filling lubricating grease into the oil reservoir, it is not allowed to use the deteriorated and contaminated lubricating grease (diluted and containing mud, sand and sundries) to prevent affecting the lubricating effect or blocking the oil passage.
5. The lubricating grease shall fill the whole oil reservoir tightly.
6. When operating the hand pressure bar, the hand pressure bar should be opened and closed to the maximum position. If the hand pressure bar is pressed back and forth several times without resistance, and the handle remains in place, it means that the lubricating grease has not been injected into the grease nozzle. The following aspects should be checked:
The valve spring at the head of the grease gun: if the valve spring is broken or fatigued, replace it with a new one;
Whether there is air in the gun barrel: if there is air in the barrel, loosen the screw and lower the hand-pressure bar to exhaust the air, and then tighten the screw (if the hand-pressure bar can see grease overflow without crackling, the air has been exhausted);
The grease can not be squeezed out and there is no resistance feeling when pressing down the hand pressure rod. The pull rod also enters the cylinder completely, indicating that the lubricating grease in the cylinder has been completely filled, and new grease should be refilled.
7. After equipment maintenance, put the grease gun in the tool box to prevent mud and sand from entering. If it is not used for a long time, the lubricating grease in the grease gun shall be squeezed out and the inside and outside of the barrel shall be cleaned and placed in a proper position to avoid compression and deformation.
8. Do not use the grease gun as a hammer to hit other objects to prevent damage or deformation.
