Instruction using a McCulloch chain saw.

here is the manual.

page 15-16 are not clear to me.

there are two triggers under the handle.

the one in the front can be pressed, when the one in the back is pressed.

the unknown is how to get the chain to turn.

Does the chain-break bar move forward and backward? Backward should be OFF (chain will move).

If the bar moves but the chain isn't released, then either the chain-break itself is not releasing, or the chain is too tight.

Can you put the chain down any at all? About midway on the bar, you should be able to pull the chain far enough out of the track to see about half of the "guide".

>> ...chain-break bar move forward and backward

Check this with the chainsaw OFF. Sometimes the Safety bar is hard to move, if it has been sitting awhile.

Does the chain-break bar move forward and backward?
...........no.............

If the bar moves but the chain isn't released, then either the chain-break itself is not releasing, or the chain is too tight.
..................the chain saw has not been touched since it last started and worked fine, so chain too tight or chain break not releasing, appear not to be a problem. I'm not getting past the "press the trigger, press the throttle button, release the trigger," step.

..................the chain is not tight on the bar, it is normal and started and ran fine, last time at my Uncle's house. It was turned off, into my car, stayed there for a week, taken out, started fine.
I can not get the trigger to do what is explained on pages 15-16 of the manual.

If the chain break bar is the part shown in the first photo, it is not moving with the engine on or off.
I am not clear on the trigger - throttle button - trigger release

There are two triggers under the handle. Then a black button on the side of the handle with a spring. None of these parts stay where I put them, they all release.
With the engine running for about 5 minutes or more, I could not get the blade to move or the break bar (top photo) to release. It all worked fine and cut wood, the very last time out.

It's full of oil, fuel, chain not too loose or too tight, etc.

coral47: The best I can tell from the pics and manual, the 'rear trigger' is another safety. That needs to be pressed before the 'front trigger' (actual throttle) will work. The 'button' should be the 'throttle lock'. With the throttle (front trigger) pressed, push and hold the 'button', release the trigger, then the button. The throttle should stay in it's 'run at speed' setting.
-------------------------------------------------------------

Ugly photo, but I think I have the sequence now.
Pressing trigger A, allows trigger B to be pressed.
Then press the button at C, and release the B trigger, and the B trigger holds.
I'll try this and see what happens once the engine is started. Rain will be over in a couple days.

>> I'll try this and see what happens once the engine is started

Sounds good.

Now you just need to get the Safety Bar to move, so the chain will unlock.

I ran it for about 5 minutes last weekend trying to get the safety bar to move, etc.
It smoked a little.

The rain is about gone,
I'll try this again on the weekend.

The rope broke, so I need a new rope.

The safety bar was just fine. It needed more force. It moves maybe an inch when on versus off.

Removing the cover, to fix the rope, showed a air filter that was at least 95% blocked. It should start fine with a new rope.

the question was asked, about the sequence of events to get the triggers to operate as they should.

Thank you much.    : )

>> The rope broke...

That sounds about right.   : /
