We will now discuss the ms 661 problems, their reasons, and their symptoms. Already we have shown the possible causes as you can see in the table. Let’s start discussing.
Reasons And Solutions Of Not Enough Power
If your chainsaw is not producing enough power, there are some things you can do to make it more efficient.
When your chainsaw is not producing enough power, it could be because the engine is dirty. This could happen if you use the saw in wet conditions or cut damp wood. What’s the remedy? Remove the exhaust system and switch to a different ignition system to ensure proper operation.
If that doesn’t work, then your problem may lie in your fuel tank. Your fuel tank may be too full. There will be no room for extra fuel when this happens, so the engine cannot get enough of its required power to run at max efficiency. To fix this problem, use a hose to siphon out some of the energy from your tank, so there’s ample room for it to continue running smoothly.
Reasons And Solution Of Chain Slipping
The MS661 has the power to cut through logs of up to 15 inches in diameter and with a 3/8-inch cutting depth. The chain can cut through anything you throw at it. However, this power comes with some limitations, and if the chain slips for any reason, it will just stop working.
Reasons And Solution Of Poorly Aligned Teeth
It has a vibrating chain bar that cuts the wood by moving back and forth. It does this at a high-speed rate, which can wear out the alignment of your teeth.
This means that one tooth might be over the other. It will make it difficult to cut through a material—or worse, cause you to break your chain.
- Use the depth gauge tool to measure how much clearance is between two teeth;
- Remove any excess material from the top jaw with a file; and
- Turn the depth gauge up or down accordingly so that there is no clearance between two teeth.
Reasons And Solution Of Hard Starting
When a chainsaw starts, it needs to overcome a certain amount of inertia before the engine is fully engaged and starts spinning. If you have a hard time getting your chainsaw to start, this means that the starting cord is too taut.
If you’re having an issue with your chainsaw starting, we recommend cleaning your air filter and fuel tank and making sure that they are not damaged in any way.
If you still have problems starting your chainsaw after this, we recommend checking for any signs of dust or dirt on the spark plug and adjusting the carburetor screws as needed.
Reasons And Solution Of Chain Overload
An overloaded chain is one whose inclination and location just on bars are out of alignment. There will be a deep groove on one side of the bar and a very shallow groove on the other side when this happens. The more external track will have a more noticeable curve than the other side.
The first step to fixing this problem is to loosen your bar bracket bolts so you can move your chain cage up or down as needed. The next step is to tighten those same bolts so you can lock in your desired position.
It’s important to note that if you don’t want to constantly readjust your chain cage, then you should alternate between using left and right-handed cuts instead
Reasons And Solution Of Chain Breaks
Chain breaks happen when the chain becomes worn out and breaks. The best way to recognize a chain brake is to inspect your chainsaw for a ticking sound. If you hear a ticking sound, this means that the chain is about to break and may need to be replaced soon. So basically, you can say this is Stihl ms 661 cm problems too.
But other signs that indicate a chain break are:
- The power of the saw drops;
- The chain may stop moving or pull off the bar; and
- Poorly aligned teeth on the chain.
Luckily, you can use some easy solutions to fix a broken chain. One of the most common ways is by using a vice grip so that it doesn’t run away from you while removing it from the saw. Another solution involves using pliers to loosen up the tabs on the side of your saw so that they can slide out easily. When you have removed one of them, use two pliers on either side of the rest of the tabs and then pull them out as well.
When replacing your chainsaw’s chain, remember not to over-tighten it because doing so will cause it to go back too far when cutting, which will lead to another problem down the road.
