20 Most Recent NRS Paslode 501000 Powermaster Plus Clipped Head Nailer Questions & Answers

Your o-rings are wore out. Paslode makes(made) a Tool Repair Kit, PN219235 and Trigger Valve Kit, PN219224 for your gun. Always use all of the o-rings in the kit and liberally lubricate them before installing them using grease in the kit or nail gun oil. If the kits are no longer available you'll have to get a breakdown of the gun, (www.paslode.com/uploadedFiles/PowerMaster_Plus_Parts_Diagram_Schematics.pdf) and order all of the o-rings. Be very carefull to put everythng back together properly, you are working with a gun.

Remove the 4 head screws and the head assembly. With the head upside down make sure the head valve works freely by pushing it down with your thumbs then releasing. If working correctly there should also be a small bit of air that comes out of the hole in the head casting when you are pushing and releasing the valve. You can feel the air by holding the head near your cheek while working the valve. Also make sure that the big round seal on top of the cylinder is not broken or has any imperfections.

DO NOT USE!!! You will destroy the tool. This symptom indicate that gasket is blown, you need to change gasket and new o-ring. It is simple job, you can do it yourself or send to repair centre.

This can be more serious problem like cracked casing or piston but these are rare, most "popular" is gasket.

Paslode framer has a lever inside of trigger that may be bent or missing. Easy to check. Remove air line and nails. Remove trigger by pulling pin. Check under trigger for missing parts. Test gun by connecting to air and place nose of gun against wood or hard rubber and then depress firing pin. If gun fires then problem is with lever under trigger or safety mechanism which is in two parts. Check safety for bent or broken piece, usually upper part will be missing lip that actually pushes on the lever. If however gun does not fire when firing pin is depressed, time for replacing orings in gun. Parts are available at www.toolpartsdirect.com . Good luck with your repair and post again if you have other questions.

Most common cause for driver not returning is a worn or missing blade seal which is a washer with a slot found under lower bumper. Remove head and cylinder. Check that driver is not bent and slides snuggly thru slot in washer. If washer seems ok then check for missing check seal oring found at lower end of cylinder. Clean the holes under check seal. Finally check oring at driver piston. Oring should just hold piston in place without sliding down cylinder. The driver should not be too tight nor too loose. Re-assemble using silicone paste on all orings (small tube of silicone available at Lowes plumbing department, used to lube faucet orings). Good luck and post again if you have other questions.

There is a large diaphram inside the nailer (inside) that is out of place or damaged.

Remove the 4 screws to access the diaphram and inspect it.

You should just be able to pull the cartriage slide at the back of the loader. it sometimes sticks, give it a good yank/

Hi,
Sounds like you need a trigger repair kit. That`s around $15
Thanks,

Take 4 bolts off of head . Clean and lube head valve with air nailer oil. Not wd40

it's usually one of the "O" rings not sealing the air completely. it will probably get worse with use, and when it's cold

This is usually indicative of a broken tank check valve. It's a valve on the pressure line from the pump to the tank. It let's air into the tank then closes so the pressure switch can bleed the air out of the pressure line and head through a plastic or copper line so the motor can restart when the pressure drops. Rarely you can remove the valve and clean the seat and valve but more often than not it has to be replaced.

Often this is caused by a brad being bent and causing the striker to stick. clear any jams, oil it and try again.

how to solve the this alaram what is the reason getting this alaram ,how to fault finding

Not being sure about this model but do you have the air hose connected to the tire vent and does it meet the minimum requirements? This may be the only way that the compressor can know how much pressure is in the tire and to start counting.

I have not been able to purchase replacement parts for these nail guns , however, have repaired them using parts from Bostitch framers and or just make the part. If the seal fits over the top of the cylinder, then try using seal from Bostitch framer part #N70155 fits a bit tight but works. Heat with a hair dryer to soften and install. If the seat is incorporated within the head valve, just dig it out and replace it with liquid two part urethane. Just mix and pour it in. After cleaning out the old seal, place head valve on level surface and pour in the mixed urethane till slightly over full to give the seal a nice crown. The finish nailer might also be repaired using other brand of seals. Remove the old part and take it to service center for a possible match. Good luck with your repair.

Change of Pressure sensor. Or Recalibrating is required.
