I bought my husband a 2 pc. chainsaw set. Blue Max 14"-20" It will not stay powered up to make a cut, after it is started. We need to know where to take it for service, or what process is needed for a

Question edited for clarity.
Question moved to our only Bluemax category.

The plug gap should be at 0.5 mm or .020"

The carb is factory set you need to remove carb you will then see two screws one marked L and the other H with a small hacksaw cut a slot across both screws don't worry about cutting into carb body this can't be helped screw both screws fully in then back them off 1 and 1/4 turns this rough sets high and low running start saw set low speed first adjust screw in or out to get best low running then rev saw to max.and adjust max revs do the same as you did with the low speed screw to obtain max revs this should solve your problem.

if it runs ok after you get it started it could be the starter pulley. the blue max saws have that problem

adjust the L screw in fully till right in,then out 1.5 turns,same with H screw.Then start saw,adjust L screw in or out slowly till you get max revs.You may need to lower idle via idle screw if revs too high.When screw cant acheive better revs,reset idle.Then,rev saw to max revs,adjusting H screw to get max revs,then when max revs acheived,turn screw anti clockwise 1/4 turn out.That gives it enough petrol to cool the tip of the plug

I also have a BlueMax 45cc chainsaw that I could not start right out of the box. I got lucky a couple of times after many (20 or 30 pulls) but normally I just gave up. Many others online seem to be having this problem with this chainsaw.

It turns out the solution for me was that the starting instructions in the manual are not really complete, there is another step that aids in starting: it needs some throttle. The chainsaw does not like to start with power at idle. After setting the switch to on and setting the choke, as the manual says, before attempting to start, squeeze the throttle while pressing the side button to lock it. For me, this allowed it to FINALLY start with only a few pulls. I learned this when I ran across this video:
How to start BlueMax Chainsaw 45CC

Hope this helps anyone else who runs into this.

without knowing which drill you have or the number of settings available I would start about four positions back from max power and try that.Thank you.

IN SOME MODELS THERE IS 2 SCREWS NEAR THE CARB.THE SMALL ONE IS FOR LOW REVS AND THE BIGGER IS FOR HIGH.START THE MACHINE AND PLAY AROUND WITH THE SMALL ONE UNTIL YOU GET THE RIGHT LOW REVS,LEAVE THE HIGH AS IT.

I ALSO SUGGEST TO DO A TUNE UP.

If you need more help post back!
Thumbs and testimonial are welcome! .

Two things that can cause this problem. 1. Your carburetor is not set properly and is not letting the engine get enough fuel under a load. 2. Your chain is binding when you put the chain bar down on the log. Make sure your front chain sproket is turning free and is not too sloppy.

Every year the spark plug must be replaced on chainsaws for the best performance.

So your current plug is probably fouled or has an incorrect gap from last years use.

Record your chainsaw's make and model number then go to your local large hardware store and to the lawn area, they will have a replacement spark plug. And if you don't have a ratcheting socket wrench set with spark plug removal socket, this is a great time to get one. the size will be 5/8 inch.


Always use Safety glasses and ear protection.
