Ryobi 105r overheating

There could be a few potential causes for this issue with your Ryobi battery-operated trimmer:

1. Battery issue: If the battery is low on charge or not able to provide enough power to the trimmer, it may shut down when operating at full throttle. Try charging the battery fully and see if the issue persists. If the battery is old or damaged, it may need to be replaced.
2. Overheating: If the trimmer motor or battery overheats, it may shut down to prevent damage. Try using the trimmer for shorter periods of time and allowing it to cool down between uses.
3. Trimmer head or cutting line issue: If the trimmer head or cutting line is damaged or worn, it may cause the motor to work harder than normal, leading to overheating and shutdown. Check the trimmer head and cutting line for damage and replace as necessary.
4. Trigger or motor issue: If the trigger or motor is faulty, it may cause the trimmer to shut down when operating at full throttle. Contact Ryobi customer support or a professional repair technician for assistance in diagnosing and repairing the issue.

Overall, it's best to start with the simplest potential causes first (such as the battery charge level or trimmer head condition) before moving on to more complex issues like faulty triggers or motors.

I been having the same problem with mines as well and it smokes sometimes when it cuts off

problem in the motor
smoking from the motor indicates burnt wires
make sure that you have the correct teeth pitch for the material being cut
is the voltage for the moor the same as the mains voltage supplied

Overheating can be caused by blown head gasket ,coolant leak from pipes, radiator, water pump faulty or lack of water
the boom you have a blown engine requiring a stripdown and quote for rebuild may be cheaper to fit a reconditioned motor

I would make sure your blade depth is just above the material.And make sure you have the proper blade for the material it seems the more teeth per inch help but also if it` s carbide or diamond tipped.

Check that the chain is on the right way around. The cutting edge of the teeth on the chain, at the bottom of the bar should face towards you and away from you on the top. It's most likely that the chain is facing the wrong way. If you don't know how to fit a chain look at the video on http://www.ehow.co.uk/video_4419336_replace-chainsaw-chain.htm

If that's not the problem then the chain is blunt and needs to be sharpened badly. You can sharpen it, with a special file which can be got from chainsaw dealers, or take it to a garden tool hire centre and have it sharpened professionally. It has to be sharpened professionally from time to time anyway to keep it cutting straight so if it's that blunt I'd recommend you get done professionally now.

The smoke if it's coming from the chain is caused by overheating from trying to cut with the chain which is too blunt or turned the wrong way. If the smoke is coming from the engine check your fuel. You should have petrol mixed with 2 stroke oil. The saw manual will give the ratio of 2 stroke oil to petrol. If you use too much oil or if it's not 2 stroke it will cause smoke from the engine. Also if you use cheap oil it can cause smoke. It's best to use good quality oil like husqvarna or stihl 2 stroke. These also protect the saw better than the cheap brands you get at car service stations which are really only meant for boats which are water cooled.

After you line up the two triangles, push in and lift. Only the top piece will come off, then the spool is inside. I kept trying to lift the whole head and then the top popped off and I realized what I was doing wrong. It is actually quite easy once you figure out the correct way and where to pull.

Sounds like the run capacitor has given up. Or, maybe the worst is it overheated and burned the motor winding. You'll probably have to take it apart. If there is a smoked capacitor, that's probably the one you should replace. If the winding is scorched, might as well get a new motor. If both are the case, then replace the capacitor before you give up on the winding.

You need to Change the Thermostat.

there is an overheat stat and this is cutting the oven off
things to check are.
is casing fan running ok? (this is the tangential fan inside the casing at the back and not the fan inside the fan oven)
this second fan is turned on by a fan stat. maybe this is faulty
is there plenty of ventilation?
is oven in fact overheating?
