Grease doesn't come out defective
I would think this grease would work for all Makita Hammer Drills. Unless yours operators manual mentions a specific type! https://www.homedepot.com/p/Makita-100-ml-Hammer-Bit-Grease-194683-7/205182387?mtc=Shopping-B-FBT-G-Multi-NA-Multi-NA-Feed-PLA-Catchall-NA-NA&cm_mmc=Shopping-B-FBT-G-Multi-NA-Multi-NA-Feed-PLA-Catchall-NA-NA-71700000014585962-58700001236285396-92700010802552397&gclid=EAIaIQobChMIudj60JXi5AIVB_5kCh0ZxQ-KEAQYAiABEgK-W_D_BwE&gclsrc=aw.ds
I just pressed down on the top plunger a couple of times to pump out grease. I don't believe the grease is pressurized. Try pumping a few more times!
