tighten all the way the side that flaps should be flush to head

Check your wiring, Line to line, load to load. Line is power coming in, load is to the motor. Check for packing that should have been removed. Inspect the pressure switch contacts to make sure they open at desired psi and adjust as necessary. A nut or screw pushing on a spring adjusts tank psi. Loose unloaded spring is less pressure, tight compressed spring is more pressure before cut off..

If it's gunked up with tar, I would spray WD40 to clean it up. Silicon spray is a good lubricant for maintenance of certain tools

I would first make sure there is power going to it, switch it on, tap on the pressure/power/control switch, open it up and visual inspection of the contacts to varify the contacts are closed or on. Look for a reset button, the electric motor may have on on its end bell. Use a voltage tester as needed, caution, electricity may cause injury and even *****.

Requires 120VAC to start - will not start with an extension cord unless heavy duty cord is used due to voltage drop and high starting current demand of compressor motor.

You don't say how old this unit is. I had an older one and it had a small rust hole in it's tank. Had to get rid of it because the tank was rusted bad on the inside. Also check all the lines as they could be leaking as well. Also the one I have now leaked air because the compressor was low on oil. I got compressor oil and its ok now. Do not over fill as it will blow oil all over.

if safety is jamming, its either bent or the pin that keeps it in place is missing/broken, you can find the pin right in front of the trigger. now as far as the nails jamming could be a few things. 1. wrong nails 2.right nail but may have gotten a defective batch 3. bucket that holds nails is adjusted to wrong size. 4.nails have been dropped/ squished and coil is not round anymore 5. nose is very worn and two nails are trying to come out at a time 6. driver is worn/broken and is trying to push out two nails at one time

Could be safety foot adjustment, broken driver or worn piston oring. Remove nails from gun and point nose of gun up then down again. If the driver moves within the nailer, replace oring. If driver oring ok, dry fire the gun on soft wood. The driver should leave an impression on the wood about 1/6 to 1/8 in deep. If the tip is broken, no impression will be left in the wood or the impression will be uneven. Replace driver as needed. If driver is good then adjust safety foot to level desired. Good luck

check rigid's website or use google

replace the orings around the trigger, or buy a oring kit and replace all orings
