Stihl Hs45 Hedge trimmer problem

[Cactusjack1993]

Hi, 

 

I have a problem with my stihl hedge trimmer. The trigger seems to have lost its tightness at the top and now the blades won't rotate at all. Anyone know what would be the fix? All else fine. Photo attached

Is this screw loose? Might be a good place to start. I'd assume you've got a cable or linkage problem due to something coming loose.

Okay thanks mate I will take a look and keep you updated. 

 

Just had a look now, unfortunately hasn't made a difference. Feels like there is no spring in the top trigger

They usually have some adjustment by the carb to take the slack up from the throttle cable. 

A strimmer but same type of adjustment

The top throttle lock will only pop up if the throttle trigger is fully released which it isn't in your pic. This can be due to the carb throttle spring being broken or the spring on the throttle trigger breaking. you really need to pop the air filter cover off and look at the cable end and see if the cable has chafed/broken, if the carb spring has broken etc

Does it start and rev up and the blades still dont move? Usual problem of the blades not moving is the pin on the main drive gear has snapped.
