Various reasons, secondary switch faulty. gas out of date, gas is colld, iar leak, faulty spark unit.

Suggest you get it checked out at a repair centre.

Use 34 degree, paper collated, clipped head nails. They were always the most common strip nails years ago as Senco, Paslode, and a number of other nailers used them.

lbrication

Often a trigger leak in the NR83A is caused by a bad gasket in the head #877-327. If this is improperly installed, cracked, or overcompressed it will cause the trigger to leak.
It is uncommon for the trigger itself to be the problem.

Trigger may be dirty, as an electrical switch the contacts can be intermittent. Also check to see if the safety plunger is set to correct depth and moving freely. Dirt can build up here......

the pin pushing your nails is loose and the guides are warned .
try to change the guides and you will see that this problem will will be gone .
one last thing , make sure the coils are in good shape as it may create some feeding problems and push 2 nails at once

Hi,
Did it get dropped? The lower safety might be bent. If not, when`s the last time it was cleaned and lubed.

The NR83a has an adjustment just below the triggering plunger. It is a 6mm hex head bolt with a locking nut. Loosen the nut and adjust screw out several turns and re-test. Make adjustment as necessary. I have seen many of these gun without the locking nut which allows the bolt the adjust itself all the way down. AS parts wear this screw needs to be adjusted. The pushing lever and the plunger are wearing smaller/shorter, that is unless the locking nut was missing. Remove gun from air supply for safety when making adjustments. Good Luck an email if you have other qustion about this gun.
