What are common signs that my Milwaukee grease gun needs troubleshooting?
Common signs that your Milwaukee grease gun requires troubleshooting include inconsistent grease flow, excessive noise during operation, or the unit not priming at all. If you notice that grease is not being dispensed smoothly or there are air pockets within the grease, this can indicate a blockage or a need for priming. Additionally, if you hear unusual sounds such as grinding or clicking, these may be indicators of internal issues that need attention.
Another sign to watch for is a decrease in pressure when using the grease gun. If you find it takes significantly longer to lubricate fittings than usual or if the grease gun feels unusually light, these may also suggest that it has lost its efficiency or that there’s a more serious underlying problem. Addressing these signs early can help prevent further complications.
How do I prime my Milwaukee grease gun?
Priming your Milwaukee grease gun is a crucial step for ensuring efficient operation. To start, make sure the grease gun is clean and free from any old grease. Unscrew the grease cartridge cap and load a new cartridge of grease, ensuring that the opening is facing down. After doing this, pull back on the plunger mechanism to create a vacuum and allow the grease to flow into the pump. You may need to repeat this process several times if air has entered the system.
Once you’ve pulled the plunger back, activate the grease gun by pressing the trigger while pointing it toward a waste bin or rag, which will help expel any trapped air from the nozzle. Keep doing this until you see a smooth stream of grease coming out. This ensures that you’ve effectively primed the gun and eliminated any air bubbles which can hinder performance.
Why is my Milwaukee grease gun leaking grease?
If your Milwaukee grease gun is leaking grease, it may be due to a few potential issues. One common cause is that the grease cartridge is improperly installed or has been damaged.
