Just got the polisher. using a Kobalt 155psi, 3gal compressor with 1/4 in rubber air hose. slows down fast. what do I need to do to sustain speed.

Air Compressor is to small, need bigger..These eat air pressure..Go Electric..

You have plenty of pressure but not enough air reserve. You need a larger air tank for volume.

I think you will find the amount of air per minute (CFM) is not large enough to power the polisher. That polisher uses several CFM and requires at least a medium compressor, and the three gallon is likely too small.

you need to get a bigger compressor. To run those type of air tools I would suggest at least 33 gal for constant pressure.

With my use I usually only ran 40-50 lbs for good rpm control, and light load, and a 3/8 hose, possibly your load is overriding the torque, but at 150 lbs of pressure it is quite likely that you will need a 3/8 or larger hose for this to produce its max torque under a fairly heavy load. Dan

I have used it to polish other items. A good tip would be to reduce the amount of air pressure because of the very high RPM's it can turn using 100 psi+. I use it to polish various metal items around 40 psi so as to reduce how fast it turns. Other wise you can actually cause buffing and polishing pads to fly apart. It's well made and has been working for over 2 years of seeing lots of work!

For the first time/ new to the trade person this is a good question. " they assume we all know a air compressor is needed. that being said I would visit you tube and do your homework. all your questions should be answered there. its what helped me a great deal. pay special attention to the cutting heads and consumables. the more you know the longer they last. also study what kind of regulator you may want. this one works for a short time but you get what you pay for. good luck have fun.

One could always install a Rheostat (just like on a Router Table) and control the speed from "0" to what ever speed it will do. The low speed is plenty slow for turning or polishing anything..............if one desires very, very slow........consider the "Mini Lathe". Just suggestions.

I have not had any issues with this so far. I slow my machine down some and that seems to be the trick. Hope that helps!

I can't imagine why you would want or need this to go faster unless you have an insufficient air supply coming to it now. Make sure your air hose is large enough in diameter for the length of hose you're using and make sure your air line connectors aren't restricting your air flow. I use 3/8" air line (25 feet) and I do NOT use the standard common/cheap quick connectors that are found everywhere. Home Depot has a larger size (same thread size but larger diameter hole through the center) quick coupler that I use to make sure the air volume stays adequate.

For best result you need diferents pads an apropiate chemical, remember low speed is for buff, dont use more that # 5 to polish

I believe the manual stated 70. I found it to be ok but I get a cleaner cut when using 75 psi for 3/16 to 1/4. Speed, distance of tip to metal, clean tips, type of metal, etc. also play an important role. I set my compressor regulator to 90 and adjust the plasma cutter regulator to desired setting. Looking at buying an inline regulator on Amazon and eliminate the plasma cutter regulator and set the compressor's regulator to max (110) for quick easy adjustments for the cutter or my other air tools versus going back and forth.

That's a tough one. Seems I have to actually start using slight force at about 30 PSI. My tires need 50, so from 30 to 50 it gets a bit tiring. Still not hard, just a lot of pumping. Also seems the faster I pump the better it works. Slow and steady doesn't seem to move the gauge.

The density (type) of hardwood is going to make some amount of difference, but I was using 90psi for 3/4" maple. Can't tell you CFM because I have 150psi tank and the compressor kicks on at ~ 120psi; I was never dealing with a tank pressure anywhere near or below 90psi where the compressor was running. And I mean ... it would also depend on how fast you were nailing; it's not like this is a tool that runs continuously. Given that I would think almost anything would give you enough CFM @ 90psi unless you've got a crew all working off the same compressor with multiple pneumatic tools causing it to be continuously running (Or, you were 'Bishop' from 'Aliens' and firing 120 nails a minute, I suppose).

I own several Hitachi NR83A3 framing nailers and this compressor keeps up. If one takes the cfm of air per cycle needed for that nailer and divides it into 4.1 you get 64 cycles per minute. I do not know of anyone who can keep that up. The CFM rating of 4.1 is at 90psi and not 120 which I run my framing nailers at. I bought this compressor because I wanted a compressor I could use in conjunction with another when I needed more CFM like when I texture drywall. I like the idea that this compressor is 100% duty cycle. None of these compressors I am aware of are all that good at starting in freezing weather but this compressor seems to be the best of its type. I have other compressors which are belt driven with more power and they are much better in freezing weather but they cost a lot more and are much heavier. When the compressor first starts with no air in the tank it has a check valve at the top of the compressor that allows air to bypass the tank until it has been running for a short time. This seems to help it start when it is cold and the air compressor has not run all night. Once there is some air in the tank you never hear it again until after you drain the tank. Before I bought this compressor I looked for one with a 100% duty cycle rating and found that there are very few available. While this compressor may look like most others it is my favorite hand carry compressor. After a short time I started using synthetic compressor oil because I think that helps a compressor start easier in cold weather and helps it to last longer. Before I changed the oil I spoke with someone at the company and they were great about helping me.

It will work if you reduce the air pressure thus reducing the RPM. I use mine for sanding and polishing a lot and do not want it running at it's full RPM because it' to fast. That quickly destroys sanding and polishing disks. I generally use it around 35 to 40 psi which of course requires less CFM. My compressor is very large so CFM is not an issue. I have a small 6 gal pancake compressor for my nail guns etc. I'll hook up the grinder today and report back how it performs.

A compressor with at least a 2 gallon capacity is recommended, but 4 gallons and above is better. You don't need to sustain the power blast for 3-4 minutes nonstop, you can clean several feet, let the compressor rebuild pressure, then continue cleaning.

I would suggest at least 4-1/2" or larger in diameter. For polishing I use a least a 7"-9" polisher that is variable speed and runs at the right speed for the material you are polishing. Grinders are too fast for polishing. Some materials require a higher speed but grinders are way too fast for polishing.

If your using portable compressor, it most likely will not have a lubricator attached, unless you have added one. If that is the case, keep doing what you're doing, add a few drops directly in the coupling on the tool every 2-3 hours. Be sure to keep your tank drained of any water that might accumulate. Moisture makes the seals sticky and can cause erratic behavior with your nailer. Clean, dry air and lubricated seals makes for a happy nail gun.

"what kinda of compressor should i use for these?" Hi, I found a very nice compressor... V-Power 21 gallons and 2.5HP and max at 125psi.... It is just enough to give intermittent blasts on the impact wrench. I might add an extra storage tank to possibly kick it up to 30-ish gallons? The perfect world is 30 gal. and with 5HP might be the better spec. Hope this helps.

We run our compressors to cycle between 115psi off and 95psi on,have not had any problems yet ,keep it lubricated
