I am looking to fix my trigger on my hp1501. The trigger cover fell off and of course the two springs flew away to never been heard from again. can these springs be purchased or replaced? Or do I have to buy the whole trigger assembly? Any thoughts?

hey that's an electric lawnmower handle , you cant fool me posting this in the chainsaws section ,!!

the spring u mention it goes right back in center it holds two red handles away from switch (black thing in center) of course when your hands hold down on red handles it compresses spring and closes switch , motor brushes are most common cause of mowers not running

It is possible your linkage arm fell off or there's junk blocking that arm from releasing - you'll need to remove the top cover and inspect the linkage arm for blockage or a missing cotter or compression pin. Remove said cover and look for the trigger linkage arm off the trigger assembly. follow to the carb, watching for blockage or missing pin(s). The natural vacuum of the carb should pull the accelerator to idle, unless the configuration ( linkage) is bent or blocked. With some saws, you may need to remove more then just the top cover, and some require the removal of the safety brake bar, which can be difficult as they usually have a hidden spring that like to fly away, taking other crucial small parts with it ( I have a saw that is now brakeless because of that mean little spring!). Depending on your level of mechanical aptitude, you may want to consider taking it to a reputable shop.
Hope this helps!!

I'll send you a link of the parts diagram.

The n60fn uses two triggers, rapid fire trigger (black metal) is pictued with your post and does not need a spring. Just replace the 3 mm roll pin that holds trigger to the body of the gun and you should be good to go. The other trigger is the white plastic sequential. The sequential trigger uses a fine spring between the trigger and centered on the tva6 trigger valve. Parts and breakdown at www.toolpartsdirect.com. Good luck

There is sensor beside this cover ,surly its broken then you can : repair with new sensor or unplug the wire with this sensor..

I had the same problem with my printer. There is a switch that tells the printer that the cover is open or closed. Unplug the printer. Open up the printer cover and look on the inside right side edge. About half way back, you'll see a 3/4 inch by 1/2 inch hole where this switch resides. If you put your finger into it, you may be able to push on a lever and it will go down. It should spring back up when you pull your finger out. If you can feel the lever but it just sits at the bottom then there either this lever is broken or the spring fell off.

The problem with my printer was the spring had popped out. To access the switch, you'll need to remove the right side cover. Do this by removing the two screws in the back on the right side. Open the printer cover and find the third screw. It is located on the right hand side, near the front of the printer, on the top. Remove this screw and pop out the cover and see if you can find the spring that is attached to the lever. Make sure you do this in an area that if a small piece fell out you could find it.

Look at the switch and lever. If there is no spring attached to the lever then it is most likely the problem, otherwise the switch may be bad or the electronics inside the printer. There is a hook on the lever and one on the printer. Reconnect the spring and it should fix the problem. I found my spring had completely fallen out and fell on the floor when the cover was opened. It is possible that this spring if fallen out can fall back inside the printer so you may have to shake the printer to find this little spring. It is about 1/2 inch long. Hope this helps.

Those springs in the feed tray come out from time to time.  Glad you got it fixed.
