AIR VOLUME REQUIRED

it is a 5 hp motor and 15 amps 230 , rewiring it would require 120 vac breaker rated at 60 amps. The power would have to upgraded to #10 AW there is is no receptacle available, so the answered is no. . the the answer upgrade to 220 Vac

Oil coming out of the sander indicates that too much oil is flowing into the the supply air. The rule of thumb for oiling an air motor is 1 drop of light machine oil per minute, per 10 cfm of air.

I would not recommend it for that purpose. A polisher has a much SLOWER RPM than a sander and you would probably cause paint damage from burning, secondly the polishing pad might not be rated for this higher RPM.

Hi and welcome to FixYa, I am Kelly.

Air Tool consumptions are based on 15 seconds per minute (25%) of tool use.

Usage rates refer to the total time that air is flowing through the tool. If your applications result in more extensive usage, calculate air tool requirements as

follows.

(25%) 15 seconds = rated scfm x 1

(50%) 30 seconds = rated scfm x 2

(75%) 45 seconds = rated scfm x 3
(100%) 60 seconds = rated scfm x 4

Your impact wrench is rated a 8 CFM Cubic Feet Per Minute Usage

SCFM is Standard Cubic Feet per Minute (pre-compressed air volume)

I would be more concerned that the plumbing from the compressor tank could support the 8 CFM required by the 1/2" Impact. Remember the Air compressor will recover the pressure loss regardless of size. The only problem your going to have for "small jobs" is if you use too small of an air line to supply the impact wrench you are not going to get the full torque that it will produce to the drive head. In other words... a 1/4" supply line or 1/4 fittings anywhere in the system just isn't going to cut it even at 120 PSI. If you have the patience... a 5 gallon tank compressor that has the output volume required should be all that you need. I have been a mechanic over 4 decades and rarely have to use a 1/2 in impact for very long. Examples of 1/2" vs 3/8" useage. Wheel nuts, crankshaft pulley center bolt, some starters, steering, suspension and rear end parts. Other than that a 3/8" Impact works great.

One other thing you can do if you have an Air-Peen portable tank (with added fittings) is to add that in line with your output hose when your using the impact wrench so that you have longer use times.

I know this does not answer your what SCFM compressor is required question but it will resolve your needs. I just can't see telling someone that is a "small jobs" user to buy a larger compressor when really all they need is more volume for a brief period of time. The re-plumbed 1/2 inch output / in-line Air-Peen tank is a much cheaper and reasonable work around and you can disconnect that tank when your not using the impact wrench.
Lastly... if your inpact wrench has a SMALL male air fitting everything above will be a waste of time. You have to get that volume into the tool without restriction so that the rool will work properly for you.

check the exhaust muffler. or just take it off and see what happens.

there is usually an inlet air adjustment on the palm sander itself one of these will correct your sander.
if not, and your air supply is good. put some air oil in it or even a light weight oil will work.
if none of this is the correct action to get it going. its probably toast!

One of the cool things about the Dynaorbital Spirit sanders is that, they were designed to be the lightest sanders out there (as opposed to the Dynaorbital supreme). This is nice as it keeps hand fatigue to a minimum. Another cool thing about the spirit, is that it was designed to be able to change out the entire drive motor all at once. The drive motor being the rotor with the vanes on it. These motors are available from dynabrade directly. replacing one vane only will tear the sander body up fast. I would recommend you get the replacement motor from them. They can be found here:http://www.dynabrade.com/dyn09/intro/selregmark/index.html

TIP: When replacing the motor, be very careful not to compress the sander body (i.e. bench vice).Dynabrade sells a rubber grip collar for this operation. then you just R and R (remove and replace) the motor and yer' good to go!!

You can get new pads at the automotive paint stores in your area. They are not expensive. Most of these wholesalers have a service department that can r&r yours. Hope this helps you, Rick

Try DW40, Q20 or another penatration flued. It might be that the aluminium oxidized over time and made the surfaces powdery. If there is a rubber seal inside it would be brittle and not doing it's job any more.

* Proper match between air compressor and tool ratings. * Correct fittings that match the tool and air hose. * Well-maintained air compressor and air hose. * Correct air pressure adjustment for the tool being used.
