Chainsaw won’t start smoothly? Here are some common problems that you can check and before taking your chainsaw for servicing. Most of them are handy to maintain & chainsaw owner’s manual is great support for all of time. Particularly Chainsaw won’t start mostly be one of three things, the power cord, the starter switch, or the motor. Service technicians are expected to rely on their knowledge and experience when faced with a situation where no service information is available. You can sort out the unwanted difficult situation by best chainsaw maintenance at home.
If you have a volt/ohm meter (buy best one from Amazon) and are comfortable working around live electricity you can make a few checks that will help you diagnose the problem. Always unplug or de-energize electrical equipment before removing covers or starting service. Be careful and wear appropriate hand protection when working around sharp metal parts. First checking the outlet you are using with say a electric shaver known or else to be in working condition, then if needed check the household breakers. Next with the covers removed and the unit plugged in, check across the two wires leading into the switch. You should have 120 VAC. If not the cord is bad and will need to be replaced or repaired. If you have voltage into the switch, check voltage out of the switch with the switch in the run position. It should be 120 VAC. If not the switch is bad. Other than that, if your motor is bad you will need to replace your chainsaw.
Then you’ve checked everything: cleaned air filter, removed air filter, replaced plug, checked gap, checked spark and flywheel, adjusted lean, adjusted rich, replaced fuel, left tank cap loose, replaced fuel line.
The Chainsaw does not start?
Starting a Chainsaw, Brush saw or hedge trimmer, is simple, but in many cases you can make a small mistake that prevents the engine from starting even if you pull the rope.
It is something that can happen to users who do not have experience. Even professionals face something like that several times.
The small mistake is “Pull the rope many times than gas applied at the wrong time“.
This error results in more fuel getting into the cylinder than the machine can burn. If we keep pulling the rope, it will continue to get even more fuel, and this will make starting even more difficult. It is often said in these cases, the machine “is choked”.
And when it is choked, how is it solved?
- Make sure the switch is in the ON position
- If the machine has a fuel pump press the primer about 6 times.
- Put the air lever in the Cold Start position and then change it to Hot Start. (This will drive an axle that would keep the engine somewhat accelerated)
- Without pressing the accelerator, pulls the rope several times trying to start the engine. (Respecting all security measures)
- You may need to pull between 5 and 10 times of the rope. If there was not really, a fault it will start.
In any case, these tips are valid only when the steps to start the engine properly at the beginning.
Check for any a spark
The spark plug may be defective .Check carefully if there is any spark. The spark plug ignites the air-fuel mixture and initiates ignition. Inspect it, if the porcelain insulator is cracked, an electrode has been burned away or damaged, or there is heavy carbon deposit at the electrode. Brush the spark plug lightly with a steel brush to clean it. If this process doesn’t solve the issue, replace the spark plugs with new ones. The oil/gas mixture damaged the spark plug more quickly, so be sure to replace the spark plug once a year & adjusting the gap as advised in the owner’s manual.
If your used chainsaw idol or unused for a longtime, then the fuel may have become bad. As a unstable components of the fuel would have evaporated leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburet, generally after 8 weeks – and it won’t ignite. Drain your old oil and change tank with fresh fuel. Otherwise, you can’t start the chainsaw. Always replace the fuel once a year no matter how much you used.
Correct fuel mixture
Two stroke engines of chainsaw require a mixture of gasoline and oil. A 50-1 mixture is recommended for almost all engines of this type, use synthetic oil designed for two-cycle. Never to use automotive or boat oil. That’s 2 1/2 ounces of oil for every gallon of gas. Make sure you are using two-cycle oil. To ensure the correct mixture, drain the oil from your engine. Mix the gas and oil in a fuel can and shake it properly. Put the fresh fuel in your gas tank. Mix the Right Oil and Right Gas in the Right Ratio. Your chainsaw manual guide the specifies the ratio to mix for your chainsaw.
Is smoke coming from chainsaw? When you smell of fuel while you try to start your chainsaw, your engine may be flooded. Remove the spark plug to check for moisture. Too much fuel on the engine is a cause of moisture. Through the fuel with spark plug hole and put in a fresh spark plug.
Dirty air filter
Most starting issues are caused by dirty air filters. Check the air filters of your chainsaw. If it is blocked, it will produce too much gas in comparison to the amount of air – as if the choke is always on – or it will block the flow of fuel. Dirty air filter decrease the performance & life of chainsaw. Keep the air filter clean. It is wise to check air filter on the unit and cleaned every 5 hours of use. Remove the air filter and wash it in warm, foamy detergent water. Rinse it in fresh clean water. Allow the filter to dry completely before reinstalling. Also check the muffler after every 25 hours of use. Inspect like spark plug, if found any damaged, replace it….Check Amazon Price
You might also pay attention to if your best Chainsaw won’t start
The rope won’t be able to recoil onto the chainsaw pulley if the rewind spring is broken. The rewind spring recoils the starter rope onto a pulley. As a result, the engine may be difficult or impossible to start.
The engine won’t turn over and the chainsaw won’t start, if the recoil starter assembly is defective. Remove the starter assembly and observe closely if it is functioning properly.
Recoil Starter Pulley
The recoil starter pulley retracts the starter rope when the rope is not in use. It won’t retract the starter rope, if the recoil pulley is broken or stuck. As a result, the engine will not start.
Always maintain Chainsaw if won’t start
- Spark Plug
- Ignition Coil
- Engine lacks power
- Engine smokes
- Chain doesn’t move.
- Chain clatters
- Check the Guide Bar
- Inspect the chain brake
