Question: Loose Driver

Jeremy

If I tilt my rn46 back and forth with no nails the driver slides back and forth (will not stay in the returned position) when I opened it up, a steel ball fell out, also the piston ring didn't fit the sleeve very tightly. Thanks in advance for any asistance.

Question: Will Not Work When It's Cold

josh

have a rn46 works great when it's warm out, but when it is cold it just blows air though center of the trigger has been cleaned and has repair kit in it please help me

Question: Rn46

replace bumper

Question: Driver Sticks

the beave

When I fire my gun the driver fails to retract after it drives the nail. What is the cause of this?

Reply: Driver Sticks

Chuck Nelson

The rubber covering the holes to the plenum chamber is off. Pull cylinder and replace check valve cover

Reply: Driver Sticks

curtis

When I fire my gun 2 nails will pop out.

Question: Difficult Start

Larry

The RN46 piston will not retract to the firing position. After pushing it in several times, it might start to operate and will then operate OK. However, if the air hose is removed, and pressure is lost, it is difficult to start it again.

I suspect gummed up lubricant. Would dismantling and cleaning with naptha solve my problem? Or is it a defective part?

Reply: Difficult Start

Chuck Nelson

Do not use naphtha. Replace rubber with RN46-RK

Question: Rn46 Misfire

mark

I have rn46 when you fire, 2 nails come out.
What do I need to replace?

Question: RN46 MISFEED

NEIL CHEN

The nail gun double fires, but only one nail comes out. Failure to advance next coil nail. Please advise what part has been damaged and needs replacing.
Thanks
Neil Chen

jeff

It may be:
There is a rubber damper ( item#61) on the piston sleeve,it controls air flow.
If it has broken or fallen down on the sleeve the piston will not hit the bumper hard enough to reset piston and not advance next nail.

let me know how it goes

Question: NOSE REPLACEMENT

JOHN

Hello,

Question: Help W/ Troubleshooting Roofing ...

PENSKESUX

I have a BOSTICH RN 46 NAILER that is feeding every other nail. Will a rebuild kit take care of this problem?. I have disassembled the feed piston assbly and cleaned it. Every thing looks good(no nicks or flat spots on o-rings). Are there any other things that could cause this problem?

Thanks

Mike

A broken feed spring could be part of the problem but usually misses all not every other. The most likely cause is a worn piston o ring. The piston is not being pulled back up with each shot. If you have had a broken o ring or bumper the problem can be "trash" in the supply line from the body to the feeder valve. When the gun cycles, the exhaust goes to the feed valve to power it. It will blow any particles in the body into the supply line, and not let enough air pass to power the feed valve. Ken
