Greasing will always be a mess but it Doesn't have to be a Pain this is the Milwaukee M18 grease Gun and it's the model number 2646 now pretty cool features on this Gun as well as there's a pretty cool Accessory we're going to show you as Well let's get started this is the Milwaukee M18 grease gun this is not an M18 fuel it is not a brushless motor Tool however we'll cover that here in a Moment the model number is the 2 646 -20 If you just want the tool or -21 if you Want the Tool uh with the charger uh With the bag in the back and the uh the Strap right here um and the tool Obviously and the 1 and2 amp hour 18vt Battery here on board so if you want the Kit -21 bar tool -20 now there's several Cool features on this grease gun and in Fact this is not a new grease gun this Has been released I believe at least a Couple of years uh if if not a few years But I did want to cover it because there Are some cool features on this and it's A very usable item that's that's great For maintenance in fact mandatory for uh Many maintenance items especially on Motor vehicles and heavy equipment uh Now there's a dial here that is not a Speed dial that is a dispensary dial or The amount of grease that it dispenses We'll cover that here in one moment we Also have a speed switch right here one
And two and we'll actually discuss what All that means in a moment as well right Here on the front of the tool we have a Light so you're getting that boat ready Uh for the next morning so you're up Really early or or you're up late at Night and rather than carrying a Flashlight you need a light to uh to Actually deliver that grease to those Hubs push that button right there you Get a little bit of light there on board The tool as you're using it now on board The tool we have a clip and a little Holder right there so you know keep that Nice and tidy while as tight as you can Keep a grease gun uh it'll probably get Greasy over time but still know the end Sticks in right there and then a little Clip to hold it nice and secure and then I believe that's a I don't know 3 or 4T Hose now max PSI on this grease gun is 10,000 uh however you can drop that down To 5,000 as well and we'll go over that Here in one moment uh we have a little Hole right here that is for this Strap and so if you're utilizing this Strap so maybe you're working on heavy Equipment or carrying around a tractor And rather than holding it by the handle Which is not that heavy but still you Can put this strap on throw it around Your shoulder however one Hook's right Here and the other one is hidden right Here in front of the battery in fact if
You little got this little stick up Right there if you push on that up Pops A little eyelet and now you can hook the Other end of that strap right there and Again make it easy to throw over your Shoulder and carry that around now the Wide base on this makes it really easy To sit up by itself in fact there's a Rubberized coating right here that makes It it feel nice as well when you're Setting it there it's not all gritty and And plasticky as well as the uh the tube Right here the steel tube has some very Heavy knurling right here for so it's Easy to grab even with greasy hands to Spin off this and and replace that Cartridge as you need to and we'll show How to do that here in just one moment Uh there's also another accessory that Is going to be very handy to use on Something like this especially if you're Using different greases and Then right here on the front of the tool Is a very important item a lot of times On grease guns you'll see a little thumb Screw a little nled screw uh this does Not need that we just got a little push Button and we'll show you what that is Here in just one moment now this is not A brushless tool as I mentioned it's not An M18 fuel it's an M18 grease gun when You see the M18 fuel designation that Tells us it has a brushless motor you Look in here you can kind of see the
Canned motor here this is one of those Tools that does not need a brushless Motor the brush motor does absolutely Fine it's plenty efficient to last all Day long it's also plenty powerful Enough to deliver that 10,000 PSI of of Grease dispensing um for any of your Heavy equipment out there cars trucks Things like that so there's no need for A brushless motor in this until Brushless motors get so cheap that They're cheaper than the regular canned Brushed motors but again no need for it At this moment let's go ahead and load Up this grease gun and get it ready for Use so the first thing I'm going to do Now right now I know there's no grease In here there's a little bit uh from the Factory that's in the hose there uh but There's none in this tube at least Nothing more than a little bit of Residual but before I release that Especially if there were grease in here Or grease cartridge the first thing I Want to do is pull this handle out which When you do that you're going to be Pulling against the spring and so it's Going to be a little Bit of a pain to do and Once you pull it All the way out you pull it over into This groove right here there's a Groove Actually on this Rod right here and you Slide it over so that locks it into Place so now you've got a spring that's
All coiled up here in this metal tube so That now we can put a new tube of grease In so once we have that handle all the Way Out we can spin this Off and there we have it so we can see Down the tube there there's a rubber Plunger that's now pulled all the way Back because we've pulled this Rod this Tea handle all the way back and locked It into place maybe see better right There how we pulled it back and then Slid it over it's like a keyhole right There and now that's got it locked in so That plunger is locked in all the way Back there in the Back if you want to you can clean out This grease or probably be just fine to Leave in there as well now you don't Have to get all nasty when you're Loading your grease guns and let me show You how to do that so when you get a Tube of Grease or your typical grease Cartridge sometimes you can get get These in like a sausage pack and you can Also do this in bulk where you're just Kind of sucking the grease up in the Tube but if you're doing that I'm sure You know exactly how to do that I'm not Going to go over that right now but when You get a typical grease cartridge You've got a pull top here looks like an Old soda can right there where you can Pull the top on it or maybe like your
Vienna sausages if you like those anyway And on the other end you have a just a Probably a plastic lid maybe a foil foil Cap but in this case a plastic lid Take your plastic lid off but leave your Metal tab on and so what you're going to Do is take the open end now and shove it Inside the tube now you may get a little Air pressure here but it should be fine You should be able to shove it in there And it's going to push air out that Little Keyhole right there so push that In until it bottoms out so once that Metal ring gets to the bottom right here Now we can lift this tab now there Really shouldn't be any pressure on this Pushing it out And be careful when opening your tab Because you might have a little bit of Excess Grease and you canot worry about it or You can Be kind of a pain like I am and want to Get every last piece in There and throw that Away but by the way keep your cap around Show you why Later so now we're ready to go in our Grease gun do not release this Rod yet We want to now go in our grease gun Might have to give it a little bit of Pressure and get the thread Started there we go and just seat that By hand okay now we've got our grease in
There now we need to Release this handle here so we're just Going To pull it back a little bit and Over and now we're going to shove that Rod all the way down in there now the Plunger is being pushed by a Spring but the rod is now sticking all The way through the grease so you've got This Rod sticking all the way through There and you got the plunger probably About right here with a spring behind That pushing on that and we'll take it Apart here in just one moment again and Show you what we're talking about now We're not ready to dispense yet because There's probably somewhere between the End of this tube and the actual pump There's probably a little bit of air Somewhere let me show you what to do With that So now before we dispense any liquid I'm Going to push this and we'll see if we Can't Hear okay we didn't really hear anything Uh but sometimes there's air in there And when you push that you'll hear it Actually hiss out if I pull the trigger Let's see Here so I'm not getting anything let me Push this still nothing let me show you A little Trick so I'm pull my handle back until I Get to the plunger and once I get in
There there's like a keyhole in that Plunger as well so I'm going to pull This Back and I'm going to turn it to where I Can lock it into that Plunger and now I'm going to push and I'm going to push at the same Time pull that handle at the same time As pushing This and now you see I've just squeezed Out some grease so now I know I've got Grease all the way to the head of my Pump so now I'm completely primed I've Got grease all the way to the head of The pump as well as all the way down the Hose and now I'm dispensing grease so Sometimes you may have to actually push In on that while pushing this right here To actually Prime all the air out of That you could probably run the pump for A while and do that but sometimes it's Just as easy to do that and now I know That it's primed and I need the rod back In there I can just put a little Pressure on it and turn it until I feel It go back through that Keyhole and now It will slide in and again I'll show you That on the plunger here in just one Moment now right now I have this on the On setting on this dial that means that As long as I have the trigger pulled It's going to run that pump so until I Let go of that trigger it's going to Keep dispensing grease forever or until
It runs out of Grease or until I let go Of the trigger now if I put it on one Now let's watch what it does so I've now Put the counter on one and I'm going to Pull the trigger and hold It okay it dispense that much grease and Do it Again again dispensing that much grease So basically the one is counting the Number of Strokes of the Piston so it's Delivering one stroke of Grease if I put It on five we should hear it do that Five Times which by the way I don't know if You notice here there's kind of a dead Men switch on here a lock if you will That I have to slide this over in order To engage the trigger if I have it slid Over the other way it's locked that out So push this over and now I've got it on Five I'm going to hold the Trigger and there you go so quite a bit Different of a look so this is set on One this is set on five we'll do that One more Time so you see we're dispensing the Same amount of Grease each time when We're using that dial when it's not on The on setting and we can go all the way Up to 50 and where it will count those 50 Strokes I'll just turn that down let's Turn that down to 10 and now we'll try 10 so here's 1 here's five and here's
10 now this is also in speed one now if I go to speed two what it's going to do Is increase the speed at which it Delivers however the PSI is going to Drop so in speed one I get 10,000 PSI With 3 and 1/2 o per minute of delivery Speed in speed two my PSI drops in half To 5,000 PSI but I get 10 ounces per Minute of delivery speed so I'm more Than threefold or right at threefold of Speed however my pressure has dropped in Half so now we're in speed two we're at The same 10 now let's see how quick that Will deliver That so now we're just delivering that a Lot Faster Back to speed One back to speed Two that's very interesting so the Number of Strokes at 10 basically at Double so You're uh you also have to to take that Into account as well so if you up your Speed with the same amount of counts You're going to get less dispensing of That grease so just understand that when You're using this again you're going to Drop in pressure in speed too but you're Going to increase the speed but it's Really only increasing the speed of the Pump it's not pumping more Grease okay now let's talk about a Process as well as a cool accessory to
Have with this tool Now when using Grease a lot of times you may be doing Kind of General lubrication and then you May need something for waterproof and You may need something for high temp Like wheel bearings things like that and I could go on here and I could say Okay Um I'm just going to put GP here for my General purpose grease or maybe HT for High temp or something like that however Now I'm responsible to keep that Somewhat clean so I can see it also to Be able to take some brake clean or Something and wipe that off so I can put Whatever else on it when I replace it However there's another option that will Cost you a little bit of money but I Think it's a pretty cool option so let's Go ahead and get this ready remember we Got to pull our plunger Out we don't want grease going Everywhere now we'll spin this Off and so I could definitely take that Tube out but let's do something else Right now I'm going to take the backside Off again make sure that You're got that locked out of place or You'll have spring going crazy on You probably still going to make a Little bit of a mess right Here okay so let's get this Out so now rather than using this tube I Can lay this aside fact I'll just lay it Right
Here stand it right there and look what We have right here so now we have a Clear acrylic tube which by the way Understand this uh there's no pressure Pressure in this tube or very limited Pressure so don't think that this has Got to hold up to 5 or 10,000 PSI all That pressure is Downstream of the pump So none of that pressure has to be here Yes it needs to be heavyduty enough to Be be to beat around but again this is Not a high pressure system on this side Of the pump or in this cartridge here But now what we have is when I have my Grease in There I can absolutely see what's in There I don't have to guess I can see oh That's my red high temp grease well cool Deal now let's get this in there because You can't just screw it in there if you Watch Here it doesn't even fit in and that's Because we've got a spacer right Here A Philip screw right Here and then there's a tab here and a Tab on the opposite side I need to push Those and slide this back and this Spacer right here slides out out of There put that on my other Tube and Now first let me pull the tab on This now my tube a slide in There now I can see that that's my high Temp Mystic jt6 grease in there you see
The red tube tells me right away what I'm running now before I put this cap on Let's go over this as I was Mentioning so you see the rubber plunger Right here and then we have the spring That's coiled up right there and so I'm Going To do my best to not hurt myself Here and you can see what's going on There I hope I can get that compressed Without it going crazy on me but that's What's happening inside that tube Also again right here on this plunger if I go down and turn it you see it's not Down to the bottom because it's as I was Mentioned kind of not in that Keyhole But if I turn this certain spot then it Bottoms all the way out and now I can Actually push on that as I need To so it can be kind of free plunging in In there if you will and you can also Get to a point where you can lock it out And then be able to push on that plunger As well so after hurting some cats I Finally got my plunger back in where it Needs to be and now we can push that in Here and you can see how tight that Plunger fits in that tube pressing Against the Side now we release our plunger and now We're ready to go with our high temp Let's see if we have to actually Prime And release the air out of this or Not go back to
On There we Go so now we've got our high temp ready To Go so pretty cool little accessory there To be able to see the actual grease that You've got in the gun and now if I Wanted to swap that out Again and now I've got my general Purpose grease in There now I've got pressure push that And it's already coming Out So now I'm down to my multi-purpose Grease Now now you can get the Milwaukee 2646-20 which means bare tool you get The tool no battery uh no charger just The case and the tool without the Battery and with the uh the steel or the Aluminum housing there and that's going To run you $229 now here's the kicker I just Checked the pricing on it typically it's $300 for the kit with the charger uh the Case the battery um and the tool and the Strap usually that's $300 or $299 right Now it's $229 so literally for the price Of the bare tool you can get the 1 and2 Amp hour battery the charger and the Case so I'd highly recommend it if you Don't already have a cordless grease gun Uh the accessory here the clear Accessory that's 50 bucks for that tube
Not everybody's going to want that or Even need that but I would say if you're Using the same tool to do a different Types of greases it comes in very handy Even if you can just see the color there Typically you know what color your Cartridges are and what that pertains to As far as what type of Grease it is so It still comes in very handy I will say The cardboard cartridges and you Probably know what I'm talking about Looks like paper like you see right here Fit in the acrylic tube absolutely fine However this is a plastic tube and it's A couple of thousand bigger than the Cardboard I measured it with my Micrometer it does not fit well in this So you can jam it in there but you will Have a heck of a time getting it out so If you are going to use the acrylic tube Highly recommend that you make sure that You're using the paper cardboard tube Tubes and not the plastic tubes I don't Know why this is coming in at a larger Diameter but it is again I use my Digital micrometer to check that and by The way 5year warranty on the tool 2-year warranty on the Battery as we mentioned on the pricing It makes sense to buy the kit right now Since it's the same price as the bear Tool now not sure how long it will stay That way but might be something you want To jump on or you might say you know
