I want to know what a lever in a fire place is

That lever operates the iron plate which goes from vertical to flat to shut off the flow of air up the chimney. When the fireplace is not in use, it needs to be closed to prevent drafts or air flowing in or out the chimney. It must be open to use the fireplace. Look up inside to see if you see daylight for it to be open. If it is not open when you build a fire, the smoke will come out into the room instead of going up the chimney.

Sometimes after a good knock on the side the cylinder will bind and not work correctly. Remove the head and make sure that the cylinder moves easily up and down. If cylinder is ok, then most likely the adjustment on the pushing lever set too low. New pushing lever does not come with the adjustment screw and lock nut. Adjust the screw up or down for best firing position. If the adjustment screw is in place and adjusted, make sure that the plunger is not sticking within the valve(plunger makes contact with the adjustment screw on the pushing lever). With pushing lever removed, the plunger should move easily in and out. Good luck

Check the bulbs, if OK replace switch.

Not all nailers have the ability to bump-fire. It depends on the type of trigger and the firing valve that the trigger contacts. Remove gun from air supply and remove the nails (for safety). Take a close look at the trigger itself looking for a bump fire setting. It will have a rotary dial to select single or repeat fire. If no setting, look at how the safety foot contacts the trigger's inner trip lever (the trip lever inside the trigger is what actually contacts the firing valve pin). With trigger pressed in, push the safety foot in and notice if the safety contacts the inner trigger lever. On bump fire trigger, the safety foot mech. will push up on the inner lever each time that you press in safety (and you will see that the inner lever will depress the firing pin). On single fire trigger, with trigger pressed, when you push on safety foot, the mech. will not contact inner trigger lever because the lever is too short to allow safety to make contact with it. On single fire triggers, the inner lever can make contact with safety only when trigger is in the resting position. With trigger released, depress safety and notice that safety contacts inner trigger liver and will remain in contact untill you press the trigger at which time the inner lever will depress the firing pin then fall away from safety. If you are a tinker-er, you can make adjustment to inner lever so that it will make constant contact (the rotary dial on triggers that are made to give you a choice of bump or single actually make the inner lever longer or shorter ). If you make any adjustments, make various and numerous tests with-out nails to make sure that it will not fire accidently.

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.

I don't know what you did, but when you beat on something that is supposed to glide with ease, something is wrong. Send me that thing, I'll fix it. I have been sitting around here bored to death lately. Where do you live? I was wondering what would happen if yo took the old gas tube, put crimp in it, to slow it down, and try it, see what happens. The locking lever? You mean the bolt? Is jumping out of it's track? Yikes!

Shimano make an "EZ fire" which is an integrated shifter/brake lever combination and cheaper than buying seperate shifters and levers.

It sounds like the latch is broken. Unless you are very comfortable opening appliances and know very well what you are doing, it is best to have the toaster replaced. Check if it's still under warranty, or buy a new one.
Any workarounds to block the lever in its down position are very dangerous and a potential fire hazard. You may be able to wiggle the lever into place so it catches whatever is left of the latch, but make sure it will pop up easily when the toast is ready.
I hope this helps.

from underneath most of the time

Start by making sure the dark slide is removed, the camera will not fire with it in place. The next step is to check the rotating back to make sure it is locked in either the vertical or horizontal position. Without film in the magazine, the multi-exp lever on the back must be set to show the red dot under the advance lever. You can check the camera without the back by removing the rotating back using the latch on the bottom of the camera
