What to Look for in Best Stihl Ms 170 Chainsaw

Drive Link Count Precision

When selecting a replacement chain for your MS 170, the drive link count is the most critical technical specification to verify before purchase. Most standard 16-inch bars for this model require exactly 55 drive links to seat properly within the sprocket and guide rails. If you choose a chain with 56 or 54 links, the tensioning system will be unable to compensate, leading to either a chain that is too loose to operate safely or one that cannot be mounted at all. Always inspect the stamped numbers on your existing bar or original packaging to ensure the 55DL configuration matches your specific hardware. Using the incorrect link count causes premature wear on the drive sprocket and can lead to dangerous chain throwing during operation, which is particularly hazardous when working near sensitive irrigation lines or raised garden beds.

Pitch and Gauge Compatibility

The MS 170 is engineered for a specific cutting geometry, typically utilizing a 3/8-inch Low Profile pitch combined with a .043-inch gauge. The pitch refers to the distance between drive links, while the gauge determines the thickness of the tang that rides in the bar groove. Deviating from these dimensions will prevent the chain from tracking correctly, causing excessive friction and heat buildup that can ruin your guide bar. For garden maintenance, such as clearing encroaching tree limbs near your raised beds, maintaining this precise .043-inch gauge is essential for smooth, vibration-free cutting. Always check your bar’s laser-etched specifications, as some regional variations may exist. Ensuring these three factors—pitch, gauge, and link count—align perfectly is the foundation of a safe and efficient pruning workflow in your outdoor space.

Carburetor Reliability and Tuning

The MS 170 relies on a delicate fuel-to-air ratio to maintain its lightweight power, and the carburetor is often the first component to suffer from ethanol-related degradation. When replacing your carburetor, look for units that offer OEM-spec performance to ensure the engine idles smoothly and accelerates without hesitation. A poorly tuned or clogged carburetor will cause the saw to bog down under load, making it difficult to perform precision cuts when pruning ornamental trees or clearing debris from your irrigation paths. Investing in a high-quality replacement carburetor ensures that your saw remains a reliable tool rather than a source of frustration. Look for units that include necessary gaskets and mounting hardware, as these small seals are vital for preventing air leaks that can lean out the mixture and cause internal engine damage.

Multi-Pack Value for Maintenance

For serious gardeners who perform regular seasonal clearing, purchasing chains in multi-pack bundles is a highly practical strategy that saves both time and money. Having a fresh, sharp chain ready to swap out when one becomes dull allows you to continue your garden cleanup without stopping to manually sharpen in the field. When buying 3-pack or 5-pack sets, ensure that each chain is manufactured with hardened steel alloy to resist stretching and maintain tension longer. This approach is particularly beneficial when cutting through dry, abrasive wood that dulls cutters quickly. By keeping a rotation of sharp chains, you reduce the strain on the MS 170 engine, improve fuel economy, and ensure your cuts remain clean and precise, which is essential for promoting healthy healing in pruned plants and shrubs.

Material Quality and Durability

The durability of your chainsaw components is directly tied to the quality of the raw materials used in manufacturing. Seek out chains made from industrial-grade steel that have been heat-treated for edge retention. High-quality chains feature chrome-plated cutters that resist corrosion, which is a major advantage if you store your tools in a shed or garage where humidity levels fluctuate. When assessing replacement parts, look for evidence of precision machining on the drive tangs and tie straps. Inferior metal will stretch rapidly under heat, requiring constant tension adjustments that interrupt your workflow. A high-quality chain will hold its tension throughout an entire afternoon of clearing garden debris, allowing you to focus on your landscape projects rather than constantly stopping to adjust the tensioning screw on the side of the housing.

Safety Features and Kickback Reduction

Safety should be the primary consideration when selecting any cutting component for your MS 170. Look for chains that feature low-kickback design elements, such as ramped depth gauges and bumper drive links. These features are specifically engineered to reduce the severity of kickback, which occurs when the upper quadrant of the bar nose strikes an object. In a garden setting, where you are often maneuvering the saw in tight spaces near irrigation pipes or raised beds, the risk of accidental contact is higher. A low-kickback chain provides a critical layer of protection for the operator. Always verify that the chain you purchase is compatible with the existing chain brake system on your MS 170 to ensure that the safety mechanism can stop the chain rotation effectively in an emergency situation.

Ease of Installation and Tensioning

The ease with which a chain can be installed and tensioned is a testament to its design quality. A well-manufactured chain should seat into the bar groove with minimal effort and move smoothly around the nose sprocket. When choosing a chain, look for consistent manufacturing tolerances that prevent binding or kinking during the installation process. Proper tensioning is vital; the chain should be snug against the bottom of the bar but still pull freely by hand. If a chain is difficult to install or refuses to tension correctly, it may be defective or improperly sized. For the MS 170, a tool-less tensioning system or a standard side-access tensioner works best when paired with a chain that has been pre-stretched at the factory, minimizing the need for constant adjustments during your first few hours of use.

Frequently Asked Questions

How often should I replace the chain on my MS 170 for optimal garden performance?

You should replace your chain whenever the cutters have been filed down to the wear indicator mark or if you notice the saw pulling to one side during cuts. In a garden environment, where you might encounter dirt or debris near the soil, chains dull faster than in clean timber. If you sharpen your chain regularly, you can expect to get several months of moderate use, but if you hit a stone or wire, the chain may be damaged beyond repair. Always keep a spare sharp chain on hand to swap immediately when performance drops, ensuring your pruning remains clean and efficient for plant health.

Will a 16-inch bar and chain combo fit all versions of the MS 170?

The 16-inch bar and chain combo is the standard configuration for the MS 170, but you must confirm the drive link count and pitch before purchasing. While most models use a 3/8-inch Low Profile pitch with 55 drive links, some older or specialized regional versions might differ. Always check the markings on your current bar or consult your owner's manual to ensure the new combo matches your specific powerhead. Installing an incompatible bar or chain can cause immediate mechanical failure, damage the sprocket, or create a significant safety hazard for the operator while working in the garden.

Why does my MS 170 chain lose tension so quickly during use?

A chain that loses tension quickly is often a sign of a new chain stretching during its break-in period, or it could indicate that the drive links are worn and no longer seating properly in the bar groove. During the first few tanks of fuel with a new chain, it is normal to need frequent adjustments as the metal settles. However, if the issue persists, check for excessive heat buildup caused by a dull chain or insufficient bar oil. Always ensure your oiler is functioning correctly, as a dry bar will create friction that causes the metal to expand and the chain to sag.

Can I use a different gauge chain than the one recommended for my MS 170?

No, you must strictly adhere to the manufacturer's recommended gauge, which is typically .043 inches for the MS 170. Using a different gauge, such as .050, will prevent the chain from sitting correctly in the bar groove, leading to dangerous chain derailment or severe damage to the bar rails. The gauge must match the bar groove width precisely to maintain stability during high-speed operation. Using the wrong gauge is a common mistake that ruins both the bar and the chain, and it significantly increases the risk of the chain flying off the saw during use.

How do I know if my MS 170 carburetor needs replacement rather than just cleaning?

If your chainsaw struggles to start, fails to hold an idle, or bogs down significantly under load even after you have cleaned the jets and replaced the air filter, the carburetor likely needs replacement. Internal diaphragm failure or worn needle valves are common issues that cannot be fixed by simple cleaning. If the engine runs erratically or requires constant adjustment of the high or low-speed screws to keep running, it is time to install a new carburetor. A fresh unit will restore the factory-set performance, providing reliable power for your garden maintenance tasks and eliminating the frustration of a stalling saw.

What is the best way to clean my MS 170 after working near soil and raised beds?

After working near soil and garden beds, use a soft brush or compressed air to remove sawdust and dirt from the cooling fins and the area around the sprocket. Debris buildup can cause the engine to overheat and block the chain oiler ports. Remove the side cover regularly to clean out the bar groove and the oil hole, ensuring that the oil can flow freely to the chain. Keeping the saw clean prevents abrasive dirt from entering the carburetor intake and ensures that all safety mechanisms, like the chain brake, remain free of gunk and fully operational.

Is it better to buy single chains or a multi-pack for an MS 170?

For most gardeners, a multi-pack is the superior choice because it provides backup chains when you accidentally strike a hidden obstacle, such as a wire or a rock in the garden. Having multiple chains allows you to rotate them, which extends the life of each chain and the guide bar by ensuring you are always cutting with a sharp edge. A sharp chain requires less pressure, which reduces engine wear and makes your work safer and faster. Investing in a 3-pack or 5-pack is a cost-effective way to ensure you are never stalled mid-project due to a dull or damaged cutting edge.

How does the pitch of the chain affect the cutting speed of my MS 170?

The 3/8-inch Low Profile pitch is specifically designed for the lower horsepower output of the MS 170, balancing cutting speed with the engine's torque capacity. A larger pitch would require more power than the MS 170 can provide, causing the saw to stall frequently. By sticking to the recommended pitch, you ensure that the saw remains efficient and easy to handle. This pitch is optimized for small-to-medium pruning tasks, allowing for smooth, controlled cuts that are ideal for shaping shrubs or clearing small branches without overwhelming the engine or compromising the safety of the operator.

What safety gear is essential when using the MS 170 in a garden?

When using your MS 170, always wear chainsaw-rated chaps, a helmet with a face shield, hearing protection, and sturdy, non-slip gloves. In a garden setting, you are often working in awkward positions near irrigation lines or raised beds, which increases the risk of slips or accidental contact. Proper PPE is your final line of defense against injury. Additionally, ensure your footwear provides good ankle support, as uneven terrain near garden beds can lead to trips. Never operate the saw while tired or distracted, and always maintain a clear path to retreat if a branch falls unexpectedly.

How can I tell if my MS 170 bar is worn out and needs replacement?

You should replace your bar if you notice the rails are uneven, if the groove has become too wide to hold the chain upright, or if there is significant burring along the edges. A worn bar will cause the chain to lean, resulting in crooked cuts that can damage the tree or shrub you are pruning. Additionally, if the nose sprocket is seized or shows excessive play, the bar is no longer safe to use. Inspecting your bar every time you sharpen the chain is a best practice; a smooth, straight bar is essential for the precision required in garden maintenance.
