Rn46 skipping nails what should i check first

The Bostitch rn46 is a very good nailer however suffers from the problem that you are experiencing. Easy to fix. Remove the nails and connect to air pressure (100psi). With side door open and trigger depressed, cycle the gun against old coiled rubber hose or soft wood. As you cycle the gun, check that the feeder is moving back and forward with speed and the driver is moving down then up again. If the feeder seems to move in slow motion back and forth the air passage that feeds air to the feed piston is restricted or oring/spring to feed piston is worn. If the feeder moves very fast then suspect worn driver oring. To check driver oring, remove nails and air supply and leave open side door. Point nose of gun up then down to see if the driver seems loose and is moving up and down the cylinder. When the driver oring is good, the driver will stay at the top of the cylinder. If the driver oring seems ok and the feeder moves very fast then suspect feeder spring weak or missing. I usually find that debris from lower bumper and driver piston oring shavings have entered/clogged the air passage to feed piston. Replace parts as needed. Good luck.

The bostitch nailer rn45 has an adjuster for depth on the front. Rotate the black knob for proper depth. If adjuster does not have an effect, most likely the driver oring is worn. Ez check for worn driver oring. Open side door and remove nails. Point nose of gun up then down again. If the driver moves up and down, replace the oring. The driver should stay in the upper position at all times. Good luck.

See if the driver blade is going all the way back up.

Look under the latch for debris or the check feeder pin is pushed up out of place not letting the latch close. Push the pin down into the retaining oring that fits into a slot below the check feeders. If the retainer oring is split, it will not hold the pin down.

SOUNDS LIKE YOU MAY HAVE RIPED THE DIAFRAM THAT CONTOL THE PLUNGER MOST OF THE TIME I REMOVE IT IF BAD I REPLACE IT

I would return it for an exchange, sounds like the firing valve is sticking or you might want to check for a jammed nail in the nose area. UNPLUG from air hose first.

This is a very popular gun, very light and powerful. Skipping nails is not a common problem. Here are a few things to check that would cause the issue. (First remove air hose and nails.) Worn piston oring (piston will be in the down position). Open side door and check that piston is at top. If oring ok, check feed spring under feeder claw. If spring is in place, push feeder in manually. It should be very difficult to move feeder shaft. If it moves easily then spring inside feeder chamber is broken. If ok, connect air to gun, leaving side door open (nails removed) and bump fire gun against hard rubber (or coiled rubber hose ) very rapidly. While bump firing rapidly, look at feeder moving back and forward. It should be moving very quickly keeping up with speed of driver. If it appears to be moving slowly compared to driver there is an air feed restriction to feeder chamber. Check for debris in small air passage to chamber. Remove two allen screws holding nose of gun to body and examine the small white teflon oring between nose and body(part #149885). Sometimes this oring traps dirt and grime or just simply gets pressed so tightly that center hole is restricted. You must use the correct teflon oring here because the nose and body fit so tightly together that a rubber oring will close air path. Good luck.

neither one, could be a jammed nail or an o ring issue, check for the jammed nail first and if not let me know and I will try and help.

if u are right nails for gun,then make sure when u put coil in and feed in front of firing pin the nails are straight with pin and connecting wires are not bent causing nails to fall out of alingnment.
