ms400 throttle trigger lockout issue

[johnsayen]

Hi all

haven’t even fired up the saw for the first time yet and it feels like there’s an intermittent issue with the throttle trigger lockout blocking the trigger from depressing, when the lockout is in the depressed position. I can’t tell if something is bent or needs adjustment or even a full replacement of the mechanism. Dealer service guy is off for a couple weeks so I figured I would check here first to see if anyone has any tips or has heard of this before?

thank you

Looks like this might be a quite rare problem. I’ll be sure to update once the dealer returns and I get it straightened out

About all you can do besides bringing it back to the dealer is take the top cover off and have a look around the linkage as you try to pull the trigger. Might try moving the linkage manually around the carb. If you can't get it to move then wait for the service guy to return and let them have a go of it.

I think I may have been over-reacting, the lockout issue / behavior only happens when you depress the lockout farther than it is when you hold it in a typical running stance. For example if you use one finger and press the lockout as far as it will go, the trigger hardens up which doesn’t happen with any other saw (251, 261, 500i) that I’ve run.

I confirmed it’s normal behavior today. I feel foolish now.

Likely a burr from the plastic mold. If it bothers you take it apart and smooth out any burrs with an exacto knife or some sand paper.

Montana - pick up a 400 before spring too. Then we can both roll with the 261, 400, 500i trifecta of perfection

I have to win the lottery first. Or at least another Covid stimulus check.

Your 500 was basically free though!

I'm already there. I live in a small cabin. My heat is all from the wood stove, except for the small electric thing in the bedroom that turns on at midnight.

Yup. Needs Biden to send me moor mooney for anutter saw.

I have noticed the lock on the 400 feels spongy best way I can describe it.
