Question about Stanley Bostitch Mcn150 Strapshot Metal Connector Nailer

1 Answer

Strapshot loses pressure after each nail. Removing & reattaching hose consistently fixes for just 1 more nail.

It worked wonderfully for several jobs. My compressor and hose are not the problem. Also, I hear no leaks.

I have a Bostitch SB-1850BN air nail gun (brand new) I used it for about 4 hours last week and it worked fine. Went to start using it again and it won't fire a nail at all. Is their any fixes?

Hmmmmm he said wisely.
Wonder if it got adequate lubrication?
Wonder if there was water in the air supply?
Wonder if there is adequate air pressure now?
Wonder if there is a nail jammed in the mechanism.
Wonder if there is a manufacturers defect?

Old dude recommendation?????
I'd suggest that you bring the gun back to where you purchased it and let them look. Hopefully they will spot the problem and coach you through so that you will be a happy customer.

Why dose p e come up and how bo i fix it please

"PE" error is related to the Harmonic pressure switch. Since the
part is electronic, I would suspect a clog at the air dome at the
bottom of the tub located at the rear of the machine. The pressure
switch is located at the top. Unplug the washer from power, you will need a small piece of 1/4" plastic tubing or copper tubing. Locate
the pressure switch, disconnect the 1/4" tube from PS. Attach the
PS hose to your plastic or copper extension tube. Try and blow thu.
You should hear bubbling of air. Draw alittle water in by sucking and
blowing several times. This should clear any thing lodged in the lower
air dome. Before you reattach the hose to pressure switch, first trim
1/4 '" of hose off, for a tight fit. But before attaching hose, plug in washer and Press POWER, Press SPIN SPEED, Press START
to activate pump to remove all the water left in the tub. Next lower the
Pump's Trap Door at the bottom left corner of the cabinet. Using a kitchen trash bag, Extend the black rubber hose into trash bag and remove the plug. Turn off the machine when all water has been
evacuated.. Unplug washer and reattach the hose to the pressure
switch and try again.. IF error returns replace Pressure Switch..

I have a bostitch MCN 150 strapshot that does not work in cold weather, under 50 degrees. Is there a fix for this?

Most likely worn orings in the trigger valve (# TVA14). Cold weather usually does not affect the gun, however using wrong oil would. Replace the trigger valve and /or try using power steering or brake fluid as lubricant for your gun during cold weather and regular nailer oil during warm weather as these other fluids may have a long term effect on the orings (cause them to swell slightly). You can test the other fluids for long term effect by placing an old oring in a cap full of oil for a week or so. I use two orings of the same size, one for control to compare against the one in the oil. No big deal. Also check for worn parts in the safety foot and /or worn trigger. If you have a single shot trigger (light color plastic) try using the bump fire trigger. Good luck.

Hi i have a problem with my stanly bostitch nail gun .i was using it ok for a little while then the nail stop coming out ,now all i hear is a putting sound only ,sounds like no air ,but my compressor and...

Your nailer model number is N75C-1 shares design features with many other bostitch coil nail guns. Usually, when you only hear a puff of air coming from the trigger area or within gun, the driver or headvalve is stuck. Usually easy to fix. First check the driver by removing air supply and inserting metal rod into nose of gun pushing the driver all the way up to top of cylinder (open latch and note position of driver, should not be visible). If driver is stuck due to debris, clear and retest gun. If driver is all the way up then remove head and see if the driver moves down (should move with light pressure). Headvalve should move inward with strong thumb pressure and move back out. Repair as needed and lube with silicone paste lube (sold at Lowes in plumbing department and swimming pool supplies). If both driver and headvalve look ok, then suspect trigger valve under the trigger. Good luck

Pull the trigger, no nail, only continuos air until I release tyhe trigger. not jammed, gun is clean, very new. acted that way right out of the box then it worked and then not and so on, worked...

Safety foot and lever inside of trigger are not pushing the trigger pin all the way in. To verifty that the gun will fire, remove the nails to allow for dry fire. Remove the trigger to reveal the trigger valve. Hold the gun against old coiled rubber hose or soft wood. Very quickly depress the trigger pin all the way in. If the gun fires, adjust safety foot and trigger so that the trigger pin is fully depressed when your bump fire. If the gun will not fire after adjustment, remove the head and lube headvalve/orings with silicone paste lube.

My nail gun will not fire a nail. Do I need to oil it or something?

Hello, W/D here.

Here's a couple of things to do or check:
1. Put a couple of drops of a light oil in the nailer with the trigger depressed, and the gun disconnected from the hose. Set it to the side for now, with the air inlet facing up.
2. Check the compressor outlet pressures. The gauge nearest the tank is the air pressure on the tank. The gauge closest to to the hose is the tool supply pressure. Between the gauges id the regulator, where you can increase or decrease the pressure to the tool.
3. Check your required air pressure for your nailer, and make sure that your regulator is supplying at least that much to operate the nailer.
4. Connect the nailer to the hose, Spray the underside of the nailer head (the slide assembly where the nails are driven) and try to drive several nails into scrap wood.
5. If the nailer operates properly, all's well. If it still fails to operate, place a few more drops into the air inlet (while holding the trigger down) and wait a few minutes, then try the gun again.
There are other things that can be done, but oiling the nailer should get you going. BTW, you should oil the nailer before each use, and when you put it away.
Best regards, --W/D--

The gun is difficult to get to shoot. you have to wiggle it and push the nail down to get it to shoot

Unfortunatly that is a common problem for those nailers. If you replace the contact housing assembly,that usually fixes the problem. P/N 174084 Bostitch service center will have the proper parts.

Bostitch nail gun loss of pressure, won't fire nail

Hello. I can help you. The nail gun you have uses 18 gauge brads. I would use only original Bostitch 18 gauge.

The one MM of difference you mention is the reason why you do not have the pressure you did have. Get rid of those 31MM brads and get the 18 gauge. Home Depot carries the Bostitch line. I would go there or to
