1, before use should check the valve spring, steel ball and other parts are short of, piston, oil gun head sealing, and pay attention to check the squeeze injection effect, to ensure that the maintenance work is carried out smoothly.
2、If the running equipment is checked and oiled, the mark of stopping operation should be made.
3、When oiling, the oil injection nozzle at the front end of the oil injection rod and the grease nozzle should be aligned, and the inclination should not be more than 8 °.
4、When filling lubricating grease into the oil storage cylinder, the lubricating grease which has been deteriorated and polluted (diluted and containing mud, sand and debris, etc.) shall not be used in order to prevent affecting the lubricating effect or clogging the oil channel.
5、Lubricating grease should be tightly filled with the whole cylinder.
6, operation of the hand lever, should make the hand lever open and close to the maximum position, if the hand lever back and forth several times under pressure and no resistance to the feeling, and pull the hand to keep the original position does not move, indicating that the lubricating grease is not injected into the grease nozzle, attention should be paid to the following aspects of the inspection:
Valve spring in the head of grease gun: if the valve spring is broken or fatigue relaxation, it should be replaced with a new spring;
Whether there is air in the barrel: If there is air in the barrel, the screw should be loosened to press down on the lever to exhaust the air, and then tighten the screw can be (press down on the lever to see the grease overflow without popping sound, the air has been exhausted);
Squeeze out the grease and no resistance feeling when press down the hand lever, and all the tie rods into the cylinder, indicating that the cylinder lubricating grease has been fully injected, should be re-injected with new grease.
7、Equipment maintenance should be placed in the toolbox grease gun, to prevent mud and sand into. If it is not used for a long time, the grease gun should be squeezed out of the lubricating grease and clean the inside and outside of the barrel, and put it in a proper position to avoid deformation under pressure.
8, the grease gun can not be used as a hammer to beat other objects, in order to prevent damage or deformation and can not be used.
