Check and be sure you didn't install it backwards.

Most likely loose wiring inside the casing of some kind. When it comes to chainsaws gas really is better. You can pickup a 14" at Lowes or Home Depot for a little over $100. Take care of it like the manual says and it'll last much longer than an electric one.

Sometimes saw dust and shavings block the oil port and track strip down the bar and chain there maybe a cover over the oil port remove this and clean carefully replace all remember to clean the bar put the chain on do not over tighten run the saw if there is no oil you may have damage to the oil pump this can happen if the saw was used with no oil or a blocked oil way some of the pumps will overheat causing damage hope this helps good luck

Hi, you can use any chain oil you like, manufactures recommend bio degradeable because they like to be seen as being green. Regards Phil.

Release the chain brake if equipped. Remove the drive end cover plate from the rear of the bar. Remove the bar and chain. Lay the chain out on a table or bench to inspect for sideways bending, breakage, or drive tooth damage. Inspect and clean the bar and it's oil passages in the drive end, particularly the small passages that run out to the chain groove from the large oil holes on each side. Inspect the drive sprocket for any tooth damage. Run the motor without the bar and chain for a few moments--oil should ooze out of a port on the side of the motor case where the bar fits to. If all ok, insert the bar into the space for it, pass the chain over the sprocket with the bottom run of teeth cutting toward you, and work the chain over the bar. Pull the bar outwards to tighten the chain, and fit the cover back in place (you may have to back off [CCW] the chain adjustment screw several turns). Fit clamp nut(s) (bolts) finger tight, then adjust the chain screw CW until the lower chain pulls up to the bar, but not so tight that the chain can't be moved by hand. Tighten the cover nuts and recheck chain tension. Make sure the chain is fully and carefully sharpened as a dull chain will quickly loosen due to heat and be thrown off again. Hope this helps!

If your Makita demo saw has an auto decompression feature but is not decompressing when attempting to start, there could be a few potential causes for this issue. Here are a few things you can check:

1. Check that the decompression valve is functioning properly. It could be clogged or stuck and not allow the engine to decompress.
2. Check the air filter. A dirty air filter can restrict airflow to the engine, making it difficult for the saw to start. Clean or replace the air filter as needed.
3. Check the spark plug. A fouled or worn spark plug can also make it difficult for the saw to start. Clean or replace the spark plug as needed.
4. Check the fuel filter. A clogged fuel filter can restrict fuel flow to the engine, making it difficult for the saw to start. Clean or replace the fuel filter as needed.
5. Check the carburetor. A dirty or clogged carburetor can restrict airflow and fuel flow to the engine, making it difficult for the saw to start. Clean or rebuild the carburetor as needed.
6. Check the fuel level. If the saw runs out of fuel, it will not start. Make sure the fuel tank is filled with fresh fuel.

It's worth mentioning that if the saw is still under warranty, it is best to contact Makita's customer service and ask for assistance. If you are not comfortable working with the engine, it is best to consult a professional or refer to the service manual for your specific saw.

Taking the carb completely off is not the same as just shooting gas into the manifold opening. Way to much air will keep the motor from firing. Before just reinstalling the carb remove the float bowl and check the pilot jet to make sure it is clear and not clogged. Most likely it will have a clogged pilot jet. If you just put the carb back on without checking to see if the jet isn't clear, you can try squirting gas into the back of the carb to see if it fires up. It should at least fire up for a quick second and then die out. If that happens it is a dirty clogged pilot jet. Reaffirming you will need to service your carb.

Here is the manual for it. https://www.makita.ca/data/upload/owners_manuals/DPC7311-HD%20&%20DPC7321HD-%20ENG_owner_English.pdf?tm=1645358236 Skipping at high revs could be both. I presume you put a new spark plug in and checked the gap? ..
