Question about Porter Cable Cable 12" Compound Laser Miter Saw 3802L
Porter cable 3802L laser is out. Trying to find out if replacing the power supply is the way to go (<$50) but not finding any 'known issues with saw. Local tool repair will price repair & part at least at $150.
I dont know if it is like mine,but if you can let the air out of it and remove the regulator knob,and it`s components,you may can set it to just to be open all the time,in other words,by pass the control knob valve.Shout back at me if I can help.

Remove 2 screws from under front grip and the swivel foot should slide forward and out (might need a bit of a twist to loosen) plastic grip should now slide forward and off.

Check the parts breakdown for your model and see if seal #894737 is listed. This seal is cause of problem that you describe. It is included in the rebuild kit or available separately. If this seal is not listed, then problem is fine scratches on oring contact surfaces in head. Use magnify glass to examine surface and remove fine scratches with 400 grit paper. Apply silicone paste lube to all surfaces that contact orings and seals. (Silicone lube is available at Lowes in plumbing department, used for faucet orings). Parts for gun are available at Dewalt service center or at www.toolpartsdirect.com. Good luck with your repair.
