What to Look for in Best Stihl Ms 170 Chain

Drive Link Count Importance

When selecting a replacement for your Stihl MS 170, the drive link count is the most critical technical specification to verify. For the standard 16-inch bar configuration, you typically require a 50-drive link chain. If the count is incorrect, the chain will either be too tight to rotate freely or too loose to maintain tension, posing a significant safety risk. In the context of maintaining raised garden beds or clearing small orchard debris, a chain with the wrong link count can cause premature wear on the sprocket and guide bar. Always count the teeth on your current chain before ordering a replacement to ensure a perfect fit, as even a one-link discrepancy will prevent the chain from seating correctly in the bar groove, leading to dangerous derailments during operation.

Pitch and Gauge Compatibility

The Stihl MS 170 typically utilizes a 3/8-inch Low Profile (LP) pitch and a 0.043-inch or 0.050-inch gauge. These measurements define how the chain interfaces with the drive sprocket and the bar rail. Using the wrong gauge can cause the chain to wobble within the bar groove, leading to uneven cuts and potential metal-on-metal friction that overheats the guide bar. For backyard gardeners managing irrigation piping or wooden trellis structures, precision is paramount. A chain that matches the exact gauge ensures that oil is distributed evenly along the bar, preventing the overheating that often occurs during prolonged trimming sessions. Always verify your bar’s stamped specifications against the chain packaging to avoid irreversible damage to your saw's drive system during routine garden maintenance.

Cutter Profile and Sharpness

The cutter profile, specifically the chisel or semi-chisel design, dictates how aggressively the chain bites into wood. For the MS 170, a semi-chisel chain is often preferred for general garden tasks because it holds an edge longer, especially when cutting near the ground where soil contact is inevitable. Soil contains abrasive silica that dulls blades rapidly. If you are trimming branches that hang over raised beds, a semi-chisel chain provides the durability needed to withstand minor debris contact without losing its cutting efficiency immediately. While full-chisel chains offer faster cutting speeds, they require more frequent sharpening in dirty conditions. Choosing the right profile allows you to maintain your garden landscape efficiently without spending your entire afternoon performing repetitive manual sharpening tasks on the workbench.

Material Durability and Hardness

Look for chains constructed from high-grade, heat-treated steel alloys that offer superior resistance to stretching and wear. A chain that stretches under load requires frequent tensioning, which disrupts your workflow when managing irrigation lines or clearing brush. Premium chains, such as the Stihl OEM options, undergo rigorous tempering processes that maintain hardness even under the high temperatures generated by friction. In small-space gardening, where you might be cutting treated lumber for planters or clearing overgrown woody shrubs, the ability of the metal to resist deformation is vital. A high-quality chain will maintain its integrity and tension longer, reducing the risk of the chain jumping off the bar and ensuring that your saw remains a reliable tool for seasonal garden bed layout adjustments and tree maintenance.

Anti-Vibration and Kickback Protection

Safety features like bumper drive links and depth gauge designs are essential for the MS 170 user, who may be operating in confined spaces near garden structures. Anti-kickback chains are engineered to reduce the force of a sudden recoil if the nose of the bar strikes an object. When working in tight quarters—such as pruning low-hanging branches near delicate irrigation emitters or raised-bed corners—the unpredictability of the wood's reaction is higher. A chain with integrated safety features helps dampen vibrations, reducing operator fatigue during long sessions. This is particularly important for home gardeners who may not use the saw daily; the added stability allows for better control, ensuring that your cuts remain precise and your garden infrastructure remains protected from accidental damage caused by a bucking saw.

Ease of Maintenance and Sharpening

Consider how easily the chain can be sharpened with standard files or electric grinders. A chain with a consistent cutter geometry allows for uniform sharpening, which is essential for maintaining a straight, clean cut. If you are frequently cutting wood that has been in contact with soil—common when trimming around the base of raised beds or clearing ground-level brush—you will need to sharpen your chain often. Look for chains that feature witness marks on the cutters, which act as a guide for your file angle. This feature helps beginners and experienced gardeners alike maintain the correct sharpening angle, ensuring the saw continues to pull itself through the wood effortlessly. Easy-to-maintain chains save time and extend the overall lifespan of both the chain and the saw's guide bar.

Lubrication Retention Capabilities

The design of the chain's drive links often includes small reservoirs or channels that assist in carrying bar oil around the entire length of the guide bar. Proper lubrication is the lifeblood of your chainsaw; it reduces friction, dissipates heat, and flushes out sawdust that could otherwise clog the bar groove. In dusty garden environments, efficient oil distribution is critical. A chain that retains oil well will keep the bar cooler, even when cutting dense or dry wood. This is especially important when you are building or repairing wooden garden beds, as the friction generated by cutting through dense lumber can quickly dry out a poorly lubricated chain. Selecting a chain designed for optimal oil flow ensures your equipment remains reliable throughout the entire gardening season.

Frequently Asked Questions

How often should I sharpen my Stihl MS 170 chain?

You should sharpen your chain as soon as you notice the saw pulling to one side, producing fine sawdust instead of wood chips, or requiring significant downward pressure to make a cut. In a garden setting, if you accidentally nick the soil or cut through wood near the ground, you should inspect the cutters immediately. Soil contains abrasive particles that can dull a sharp edge in seconds. Generally, for light residential use around raised beds, a light touch-up with a file every two to three tanks of fuel is recommended to keep the cutting performance optimal and prevent excessive wear on the engine.

Can I use a non-Stihl brand chain on my MS 170?

Yes, you can use aftermarket chains, such as those from KAKEI or other reputable manufacturers, provided they match the exact specifications of your saw. You must ensure the pitch, gauge, and drive link count are identical to the original Stihl specifications. While OEM Stihl chains are often optimized for the specific hardness and heat-treatment requirements of Stihl bars, high-quality aftermarket options can perform well for standard garden maintenance. Always double-check the packaging for the '3/8 LP' pitch and '0.043' or '0.050' gauge markings to ensure the chain will seat properly in your saw's drive sprocket and bar channel.

Why does my chain keep coming loose during use?

A chain that frequently loses tension is often a sign of a worn-out drive sprocket, a damaged bar groove, or a chain that has reached its maximum stretch limit. When working on garden projects, heat buildup from friction can cause the metal to expand, which may temporarily loosen the chain. If the tensioning screw is maxed out, the chain has likely stretched beyond its usable life and needs to be replaced. Additionally, ensure that you are not running the saw with a dry bar, as excessive friction generates heat that accelerates chain stretching and can permanently damage the guide bar rails.

What is the difference between 0.043 and 0.050 gauge chains?

The gauge refers to the thickness of the drive link that fits into the guide bar groove. A 0.043-inch gauge is thinner than a 0.050-inch gauge. It is critical to match this measurement exactly to your guide bar; if you put a 0.050 chain on a 0.043 bar, it will not fit, and if you put a 0.043 chain on a 0.050 bar, it will be loose and unstable. Using the wrong gauge can cause the chain to lean, resulting in crooked cuts and potential damage to the bar rails. Always check the stamped numbers on the base of your guide bar before purchasing a replacement.

How do I know if my chain is installed in the correct direction?

The cutting teeth should always face forward toward the tip of the bar on the top side of the saw. When you look at the chain, the sharp, angled edge of the cutter should be pointing in the direction of rotation. If installed backward, the chain will simply rub against the wood without cutting, creating heat and smoke while potentially damaging the bar. Many Stihl chains have a small directional arrow stamped on the cutters to help you orient them correctly during installation. Always perform a quick test cut on a scrap piece of wood after installing a new chain.

Is a 16-inch chain the best length for the MS 170?

The MS 170 is designed to handle a 16-inch bar effectively, making it an excellent choice for general garden tasks like pruning, clearing small branches, and cutting lumber for raised beds. While a shorter bar might be slightly lighter and easier to maneuver in very tight spaces, the 16-inch configuration provides the best balance of reach and power for this saw's engine displacement. It allows you to tackle slightly larger logs without overloading the motor. If you primarily work in very cramped spaces, some users opt for a 14-inch bar, but the 16-inch remains the standard for versatile garden utility.

How does soil contact affect my chain's longevity?

Soil contact is the primary enemy of chainsaw chains. Dirt and sand are composed of silica, which is harder than the steel used in chain cutters. Even a brief touch against the ground can dull the entire chain instantly. When working near garden beds, try to elevate logs on a sawhorse or another piece of wood before cutting. If you must cut near the ground, use extreme caution to avoid contact with the soil. A chain dulled by soil will require significantly more effort to cut, leading to increased fuel consumption, higher engine stress, and a much higher likelihood of kickback.

What should I do if my chain starts smoking during a cut?

Smoking is a clear indicator of excessive friction, usually caused by a dull chain, a lack of bar oil, or a pinched bar. First, stop the saw and check your oil reservoir; if it is empty, refill it and ensure the oiler port is not clogged with sawdust. If the oiling system is working, your chain is likely dull and is 'burning' its way through the wood rather than cutting it. Stop immediately to sharpen or replace the chain. Continuing to operate a smoking saw will ruin your guide bar and can cause the chain to snap under the extreme heat generated.

How do I clean my chain after working in a garden?

After finishing your garden tasks, use a stiff brush to remove packed sawdust and resin from the chain and the bar groove. Resin from pine or other sap-heavy trees can harden, preventing the chain from moving smoothly and blocking oil flow. You can use a mild degreaser if the buildup is significant. Once clean, lightly coat the chain with a thin layer of oil to prevent rust, especially if you store your saw in a humid shed or garage. Keeping the chain clean ensures it remains ready for your next project and prevents the buildup of debris that can lead to premature wear.

Are there specific chains for cutting treated lumber for planters?

While there isn't a 'special' chain exclusively for treated lumber, you should use a sharp, semi-chisel chain for this task. Treated wood is often dense and can contain chemicals that are hard on blades. A semi-chisel chain offers a good balance of durability and cutting speed. Because you are often cutting lumber to specific dimensions for garden beds, precision is more important than raw speed. Ensure your chain is properly tensioned and sharp, as treated wood can be surprisingly resistant. Always wear appropriate personal protective equipment, as the dust from treated lumber should not be inhaled during the cutting process.
