Hello Canibal, 2000 watts is the starting watt so approximately 1600 continuous watts
There is a rocker, on/off switch on the unit, to turn it on and off.
Please check with the paint sprayer manufacture for specifications on what compressor will work best with their product.
Don't need to change oil. Just make sure it's filled to fill line. DO NOT over or under fill.
Yes, but designed for that purpose.
Ham sandwich, it has electrical components. Keep it covered with a waterproof tarp and u should be ok.
Wish I could tell you. We use it frequently on jobs for crown molding and baseboard. Noise is not bad.
No. You will be under powered with this unit.
Not sure what the pressure is at the tool you’re using. For us the volume of air supplied to our nail guns is important. We run 2 nail guns. If you’re using a DA I would contact the Mfgr.
