The pin on my Dewalt dc616 cordless finish nail gun is ceasing up. How can i lubricate it? can i spray silicon into the nose of the gun?

Could be lack of lubricant or safety foot not pushing trigger valve pin all the way in. Easy to check. Remove nails and remove trigger to expose the trigger valve firing pin. Connect air and with very quick action depress the firing pin all the way in with finger. If gun fires adjust safety so it pushes on trigger pin completely. If no fire, remove head and head valve and apply plenty of white grease or silicone paste to orings and reassemble for retest. Good luck

check and see if the magazine is being obstructed are the nails feeding properly?

Probably the accuator.

Thanks,
Jeff

It sounds like the battery has a low charge or is defective, have it tested.

The bestthing to do is get you a good screw driver and just sit down and start prying it out of there, will take a minute or 2 but will eventually come out

Make sure the area where the nails slide through is nice and clean. Lubricate with some spray silicone. They may not be seating all the way against the nail driver mech.

Argh...

Had the same problem, but only after about 4-5 nails. Once it jammed 4 times in a row - very frustrating.

I read the manual, took the unit apart, checked the driver - it was straight. I took a file and filed the back end of the driver down a bit so it would miss the second nail and so far it seems to be working famously.

Great unit...

make sure the track is clean and lubricated, also spray we40 in the nose

I have both the DC616 and 618 and have used them sucessfully for about three years. Two main things go wrong. There is a drive belt that breaks (drives the spool that give the energy to drive in the nails), second are two small rubber bands on either side of the drive head that break. The bands can be accessed by taking off the front silver cover, the drive belt is access by spliting the case. Make sure you are using the correct nails or the drive pin may become bent and will jamb repeatedly. Hope that helps!
