My paslode nail gun is broken. I put the battery in and it will fire a few nails, but then the fan stops and the light will flash green then red. I have to reinsert the battery. Any ideas?

see if someplace around you sells dielectric grease. automotive store. what that does is: increase the electrical current between things, assuming that you have poor contact so few dabs of this stuff should be perfect it fills the gap between where the contact is lost and back in business.

Nail gun will not fire green light on gas ok after drop on congrete floor

A quick diagnostic check. First remove gas cell press nose against solid surface to dispose of any gas that may be in chamber.
1. Insert battery - LED should flash.
2. Press nose against solid surface - LED should be lit permanently (if still flashing possible fault moulded circuit board or fan motor micro switch lever, if flashing red green high possibility motor fault). Listen to hear fan running if not heard fan blade may have fallen off motor.
3. While still pressed against solid surface press trigger and watch LED - LED should blink off then light again (may flash red on guns newer than 2006) If does not blink fault either Spark unit (controller) or moulded circuit board trigger micro switch. To test for LED blink again release pressure on nose then press again. The blink indicates that a spark has been sent to the spark plug.
4. If 1 to 3 are OK problem most likely gas related or leak in seals. Ensure driver blade not still forward a possible fault of sticking forward after being dropped is nose slightly bent this traps the driver blade when first fired and does not return. (jammed nail gives a similar fault.) If nose is the fault it will require a new sleeve.
The moulded circuit board is normally cheapest then spark unit and sleeve roughly about same price the motor is most expensive.

Hope this has been some help to you.

Make sure that you dry the top of the motor housing and connections.Make sure that the piston is up as far as it can go.
When you depress the nose against the work the motor should run and if you look at the flashing light on the side it will stay constantly on and momentarily flash when you pull the trigger. If it goes red then check the battery is charged otherwise there coiuld be a fault with the motor.
Is the inlet Valve facing the correct way with the bottom of the "V" facing down into the machine.
Check the date of the gas, make sure it is not out of date.
Is the gas cold? warm the cylinder up by putting it in your trouser pocket for 10 min. Paslode make winter gas for these cold days.

I have a paslode airless framer that wont fire. New batterry & fuel cell. It make the noise but wont fire

Hello harderconstr, I have that nail gun myself, and when it's working good it is a great tool to have.
Here are a few suggestions.
1. Remove the battery, make sure that you don't have a nail jammed in the the firing chamber, that has happened to mine before.

2. Adjust the depth tension on the end of the gun. You should have an alen wrench to loosen the adjuster at the tip. Slide the adjuster away from the gun, ( out ) as far as it will go and then tighten it back down. Reinstall the battery and try it again. You can re-adjust the tension after you see if this helps the problem. The adjuster on my gun was worn and I needed to adjust the tension to get it firing again.
3. I also got a new battery for my gun, and what I found was I really had to slide the battery in pretty hard to get it to click in place. Also, when you hold the gun in your right hand, the thumb side of the handle should have a very small LED light, red means it's not ready to fire, green means it is ready to fire. Make sure you have a green light.
I hope this helps you my friend!

Paslode 1st fix gun .battery fully charged and placed into gun.the light flashes green and the gun will fire once after which the light flashes red and the gun will not fire.any ideas.i have tryed other...

I would look at the fuel cell on the bottom is a expiration date and they will not fire older fuel. Also do you remove the battery and it does the same thing? When you depress the safety on the work can you hear the fan motor? You say the tool is clean does it have enough lube to move all items freely. Just a couple thoughts, Also look at the spark plug wire for being broke or coming out of the spark unit. Let me know and we will go into this deeper.
