User questions & answers

Question:	Why would you lose more air when the air chuck is covering the valve stem as much as possible and it’s in the locked position
Answer:	The valve stem may be too short for the chuck to fully engage. I've had that happen before and switched a different device. You may already be doing this but, be sure the chuck is fully unlocked, then press down hard and lock while maintaining pressure to get more of the stem in the chuck. If it's already at the bottom of the stem, you'll need to have a mechanic install longer stems. Yeah, I know, pain in the neck. But, the compressor is great. Our daughter loves it.
Question:	I have a slow leak in my tire and the plug in the car doesn't work. how many psi can you do at a time. and how long does the battery last stored
Answer:	Hello, you can preset psi according to the normal value of tire pressure. The maximum PSI you can set is 100. The battery can be stored for quite a long time if you don't use it often. It has a capacity display and can let you know when it should be charged.
Question:	Can I operate this tire inflator by plugging it directly into the wall
Answer:	No. This inflator can be powered either by the 20V DC battery pack or the 12V DC Car Adapter pack. The AC charger unit can only be used to charge the battery.
Question:	Where can I get another battery? I don't find it on Amazon
Answer:	This is probably what you're looking for: https://www.amazon.com/Rechargeable-Real-time-Indicator-Compatible-Masterworks/dp/B07JHZ5CST Right here on Amazon and advertised to work with all 20V Master Works tools

User questions & answers

Question:	Do you sell the inflator holder that goes on the bike
Answer:	The cycplus a3 without a holder, but cycplus air pump A3 come with a mount.
Question:	Does it work on presta valves
Answer:	They include a presta adaptor to shrader. I ordered a presta/shrader quick Connector. (Cost 1/2 as much as the pump for a good one). I love it. The quick connect they include pulls out of the hose. I had to add an O-ring to make the new connector seal properly. It all took 15 minutes or so.
Question:	Would you recommend using this for topping off a cars tire
Answer:	Absolutely! I use mine to top off tires on my car, pickup, and motorcycle. It works great.
Question:	How long does it take to fill a mountain bike tire. Is the seal good? No leaks on removal
Answer:	I used it to put air in my tire on my car when it was low..It did not take long at all. The seal is tight. I bought this to blow up flat 10 inch play balls for my dog. It fills them rather quickly. I am impressed by this product, better than I thought it would be. Hope that helps.

Question:	Can I use a 18v battery

Question:	Can this inflate a air matress
Answer:	Yes
Question:	They should make this in 18v
Answer:	Invest in both M12 and M18, and enjoy the best of both worlds.
Question:	Will this work to top off a 2 gallon water heater expansion tanks? Need 60 psi
Answer:	Yes, it should be able to do that... as the highest setting is 120psi. On average with a fully charged 3.0ah battery... I can put about 25psi into 6 tires before the battery needs to be recharged... so get a 4.0ah or higher battery to handle the duration it would take to completely fill that tank.

User questions & answers

Question:	What is the warranty term on this item and what happens if defective
Answer:	according to the picture, D8EE is the 8000 grit. But for sure check their website at DMT for specs for D8EE
Question:	Does this device read the psi in the tire? (i mean before setting desired psi
Answer:	I’m not sure. I ordered three different ones and they all said DMT on them. I’ve had them for a few years now and they work great. Definitely worth it.
Question:	Can the adapter handle 220V electricity
Answer:	I just left the DMT corporate headquarters 2 hours ago. I went over there to buy an Extra Course bench stone direct from them. It was more expensive than these are on Amazon and I made point to mention it to them. They said they do not sell any of their products for less than their distributors and said that any deeply discounted stones may be suspect. If they don't have the DMT Logo on them they may be knock offs. They will knock off anything in China these days. I bought some sneakers which looked EXACTLY like the real things except the inner soles were different and they were made in colors not available by And1. Obviously knock offs. Take that for what it is worth. I have had 3 of the 11x2.5" bench stones for more than 20 years. I bought them from Highland Hardware, now Highland Woodworking, of Atlanta, Georgia. I also have another 1/2 dozen smaller 6x1" hand stones for portable knife sharpening, ranging from Extra Coarse up through Extra Extra Fine, with some duplication. I have not had any issues with any of them. DMT told me that they will replace any defective stones. The secret to using these effectively is to not strong arm them. They pointed out to me just today that it only takes light pressure to make them work well. These diamond stones do have to be cleaned of the swarf after use. I use Comet or similar cleaner with a Scotchbrite sponge. This is how you clean Alumina or ceramic Crock Sticks as well. I always dry the stones with paper towels and then let them air dry before I put them away. These stones do require break in. When they are new they may leave larger scratches in the blade than after they are broken in. You will also notice that they make more noise before they are broken in. You may notice the difference more in the finer grits. You don't have to do anything besides use them to break them in but they will seem to become quieter and smoother after a little use but they do not lose any effectiveness. In fact just the opposite. They will work better. If want you can use a lower quality blade to break them in particularly if you are using very fine grits on expensive knives.
Question:	What type of battery? Is it lithium ion
Answer:	My rule of thumb is to only double the git for each sharpening step. So, from 250 grit coarse to 400, then to 800, then to 1200, then to 2000, then to 4,000, then to 8,000. The last three grits are mainly for polishing. If you skip a grit, it is like skipping a grit in sanding a wood project, in that you have to spend a lot more time with the higher grit, then if you had used a medium grit. So I would say no, do not go from 1200 grit to 4000. Instead, go from 1200 to 2,000. DMT makes a 2,000 grit diamond stone by the way.
