If your grease gun won’t pump, there are a few potential causes and solutions. First, ensure you are using the correct type of grease for the gun, as trying to use incompatible types can create blockages.
Check you are inserting the grease cartridge the correct way and are firmly pressing the cartridge until it clicks into place. Also make sure the plunger is pushed all the way down before each use.
You can also try to unclog the nozzle if any grease residue is preventing proper lubrication. To do this, press a wire brush down the nozzle, twisting it to work any residue away and back towards the cartridge.
Check the o-rings to make sure they are undamaged. If any are missing or damaged, you will need to replace them. The seal at the end of the plunger may also need to be replaced if it is worn or damaged.
If these measures do not rectify your problem, then you may need to take apart the gun to check for corrosion or blockages caused by hardened grease. If needed, you can use a lubricant like WD-40 to help clear any blockages.
Lastly, check rubber or plastic parts for any cracks or other damage, as these can result in inefficiency when pumping.
How do you prime a pump grease gun?
Priming a pump grease gun is a relatively simple process that requires few supplies. First, make sure the grease gun is loaded with the appropriate amount and type of lubricant. Connect the grease gun to the grease fitting of the item to be lubricated, then open the pressure release valve located on the top of the grease gun.
With the pressure release valve open, pump the plunger several times to create a vacuum, then close the pressure release valve. Next, squeeze the trigger of the grease gun and continue to pump and squeeze the trigger until lubricant is discharged from the nozzle.
Once grease is seen coming from the nozzle, your pump grease gun is primed and ready for use. Make sure to follow the product instructions for the appropriate type and amount of lubricants, as well as any safety precautions.
Why do grease guns fail?
Grease guns fail for a variety of reasons. The most common causes for grease gun failure include air pressure problems, air line blockages, blocked grease fittings, grease gun breakdowns and inadequate lubrication.
When air pressure is too low, meaning either the air hose or regulator is set at a lower than required pressure, grease cannot be efficiently forced through the system. This will cause an inefficient transfer of grease, or in some cases, a total lack of delivery.
If any air lines or hoses become restricted in any way or blocked, then the grease pressure will not be delivered at the right levels that are needed, again leading to a inefficient or a total lack of delivery.
The grease fittings can become blocked due to a build up of gunk on the outside of the fitting from either old grease that has been congealed, dirt or other contaminants, or a build up of sludge from previously used grease.
Once the blockage has occurred, the fitting must be cleaned to allow for the effective delivery of grease.
If a grease gun becomes damaged in any way, for example by accidental dropping, alteration through improper use or by a manufacturing defect, then it will need to be repaired or replaced in order for it to work correctly.
Finally, inadequate lubrication can also lead to grease gun failure, as insufficient grease can result in ineffective lubrication, leading to the potential for corrosion, scarring and even mechanical failure.
Ultimately, effective maintenance of a grease gun and proper lubrication play a major role in the efficacy of grease gun performance.
How do I know if my grease gun is working?
To determine if your grease gun is working, you will want to first make sure the fitting is securely attached to the grease nipple. Then, check the pressure in the barrel of the gun by squeezing the trigger and actuating the release valve.
This will let the pressure escape from the barrel if the pressure is too high and the pump is working correctly. If the pressure is not escaping, it is likely that the barrel is not being filled correctly.
You should also inspect the plunger and move it back and forth to make sure it is functioning correctly. If there is any deformation within the plunger, then it is likely the plunger is not functioning correctly.
The last step is to add grease to the barrel and test the gun on the grease nipple. If the grease is not being released after actuating the trigger, then it is likely that the gun is not working correctly.
Can you leave grease in a grease gun?
Although it is possible to leave grease in a grease gun, it is not recommended. Grease left in the gun can become thick and harden, which can prevent grease from flowing easily, or result in clogs. Also, if the gun is not sealed properly, or if the grease inside is exposed to air, the grease could become contaminated.
This could ruin the grease and lead to equipment failure. If you decide to leave grease in your gun, it is important to make sure that it is properly sealed and stored in a cool, dry place. Be sure to inspect all fittings and connections before use.
Additionally, it is important to replace the grease after a few months to ensure that the correct amount is being dispensed and that the proper lubrication is being provided.
Which end of grease tube goes in first?
The end of the grease tube that is rounded and has a pointed tip is the end that should be inserted first. This end will make it easier to insert the tube into the opening of the greasing fitting. You should also make sure that the opening of the fitting is clear of any debris before attempting to insert the grease tube.
Once the pointed end of the tube is inside the fitting, you can slowly squeeze the other end of the tube to begin the flow of the grease. Once the grease has begun to flow, you can continue to squeeze in intervals to make sure that all of the bearing surfaces are adequately lubricated.
After you are finished greasing, be sure to wipe away any excess grease with a paper towel and discard properly.
How much grease is in a grease gun pump?
The amount of grease in a grease gun pump depends on the size of the grease gun, as larger grease guns may hold more grease than smaller ones. Generally, grease gun pumps of the standard size will hold up to 3-4 ounces of grease.
The lubricant typically comes in bulk-sized containers and must be manually loaded into the reservoir of the gun. Depending on the type of grease you are using, many times the container or tube of lubricant will come with a designated plunger or adapter for easy filling of the grease gun.
Why is my grease gun not pumping?
First, it is important to ensure that the nozzle is properly attached and sealed to the grease gun in order to ensure an air-tight seal. If air is leaking in, this will prevent the grease from being properly pressurized.
Additionally, make sure the nozzle is undamaged and the threads are in good condition.
Second, ensure that the spring-loaded plunger is not stuck and that the pump is able to move freely. If the plunger is stuck, it will prevent the grease from being pumped out. Try cleaning the plunger and thoroughly lubricating it before attempting to work again.
Third, check for any obstructions in the tip of the gun. If the nozzle is clogged with debris, this can easily prevent the grease from being pumped out. To clean the nozzle, unscrew it from the grease gun and make sure no debris is blocking the opening before reattaching it.
Lastly, make sure that the grease is still in a usable condition. If the grease has thickened, it will require more pressure to be able to exit the gun, so it may be necessary to warm the grease before attempting to use the gun again.
If after trying all of the above steps, your grease gun still isn’t pumping, it may be necessary to consult a professional or purchase a new grease gun.
Are you supposed to push the plunger in on a grease gun?
Yes, you should push the plunger in on a grease gun. The plunger is what forces the grease out of the gun and into the desired area. As long as the barrel of the gun is filled with grease and the plunger is in the ‘down’ position, you should be able to press it in and the grease will come out.
Be sure to pull the plunger all the way out before refilling the barrel with grease so that the plunger’s seals don’t get clogged with excess grease. You may need to hold the barrel of the gun securely as you push the plunger in so that the gun does not vibrate and move around too much.
It is also important to make sure that the head of the gun is positioned firmly over the area where you want the grease to go before pushing in the plunger. When you are done greasing, make sure to clean the barrel and plunger of extra grease so the gun is ready to use the next time.
What are the parts of a grease gun?
A grease gun is a handheld tool used to apply lubricating grease to mechanical equipment. The parts of a grease gun typically include:
• The barrel, which is the main body of the grease gun where fresh grease is loaded.
• A handle, which is used to pump grease out of the barrel.
• A plunger, which pushes the grease from the barrel through the nozzle and into the desired spot.
• A trigger, which is used to release grease from the barrel once the nozzle is in position.
• A nozzle, which is a fitting connected to the end of the barrel to direct the flow of grease.
• A seal and release valve, which allow for easy release of grease from the barrel and prevent leakage when the trigger is released.
• A follower rod, which helps to evacuate air from within the barrel as well as draw fresh grease into the barrel.
• A priming pump, which is used to force grease into the barrel before pumping it out.
