The plastic triger on my husky impact tool comes off,

If you are experiencing issues with the trigger on your Husky 2190 HFC framing nailer and don't have the user manual, here are some general steps you can take to troubleshoot and potentially fix the problem:
1. Safety Precautions: Before attempting any repairs, ensure that the nailer is disconnected from the power source and there are no nails in the magazine.
2. Visual Inspection: Inspect the trigger mechanism for any visible damage, debris, or misalignment. Look for any loose or broken parts that may be affecting the trigger's operation.
3. Lubrication: Apply a small amount of lubricating oil specifically designed for nail guns to the trigger mechanism. This can help ensure smooth movement and proper functioning of the trigger.
4. Check Spring Tension: The trigger mechanism relies on springs for proper operation. Check if the springs are intact and properly tensioned. If a spring is damaged or too loose, it may affect the trigger's performance.
5. Adjust Trigger Depth: Some nailers have a depth adjustment feature that allows you to control how far the nail is driven into the material. Ensure that the trigger depth setting is properly adjusted to the desired level.
6. Test the Trigger: Reassemble the trigger mechanism if you had to disassemble it for inspection. Test the trigger to see if it operates smoothly and consistently. Check if it engages and releases properly.
7. Seek Professional Assistance: If the trigger still doesn't function correctly after attempting these steps, it is recommended to seek assistance from a professional tool repair technician or contact Husky customer support for guidance. They will have the expertise and access to specific parts and information to help you resolve the issue.
It's important to note that working on power tools can be dangerous if you are not familiar with the proper procedures. If you are unsure or uncomfortable with any step, it is best to seek professional help.

MUITO OBRIGADO EU NAO ACHEI EM LUGAR ALGUM?
TANK VERY MUCH.

In the 400 series of Huskies I have fixed, the handle comes apart with several screws. Sounds like the simple problem might be in the handle/trigger assembly. The more complex problem is if the throttle linkage rod popped out of the throttle. The outside trigger interacts with a black plastic insert and spring that provides pressure outward to keep the throttle low. This assembly connects to a thin metal rod that looks like the path a drunk would take doing a sobriety test after too many martinis. The rod goes into the housing and connects into a hole in the throttle assembly, then is locked in place with a plastic piece that slides down to keep the rod from falling out. In order to see this area, the cover needs to come off. I'll be honest. The last one I had, the rod fell out of both ends. It took me two days of pondering, playing around, cursing, getting up and walking away, then coming back to finally figure out where the ends went. The blue plastic piece had slid down, covering the hole, so I was at a loss as to where it attached to the throttle. NOTE: When removing the handle, try real hard to keep it together until all screws are removed. THEN VERY CAREFULLY begin to take it apart, looking in from the top of the handle. You might get one good glimpse of how the parts fit together before they fall apart on you. Husky does have a good website for exploded view diagrams, but sometimes they leave a little to be desired for 2-Dimensional art vs. 3-D Reality. Good luck.

get some air tool oil and put it in the hose connection and manually turn the socket end by hand,the air vanes have frozen in place and can't hold the air in to operate the unit,make sure when you do this squeeze thge trigger to let the oil into the units barrel,then connect to an air supply and try it,you may need to help get it started by hand,then let it run and add some more air tool oil again to keep it lubed

Page 5 The connectors are 1/4 pipe threads . remove plastic plug and install male fitting into gun.

The seal is bad inside leaking air pressure to the gun without squeezing the triger. Get a reseal kit from Sears

there is a neoprene O ring in the trigger area ,that breaks down ,it needs a service by an air tool repairer ,it is not expensive. dont use wd40 or the like if dont have airtool oil use auto transmission fluid and this wont happen too often

try lubricating it with air tool oil, put ten drops in at the air nipple, try tapping unit on table as you press trigger in and out.
