Understanding Chainsaw Chain Basics: The Foundation for Cost-Effective Replacement

Before we dive into the tips, let’s get a handle on some fundamental chainsaw chain terminology. Knowing these terms will empower you to make informed decisions and avoid costly mistakes.

Chain Pitch: The Spacing Between the Links

The pitch is the distance between any three consecutive rivets on the chain, divided by two. It’s typically measured in inches. Common pitches for Poulan Pro 18″ chainsaws include .325″ and 3/8″.

Why it matters for cost: Using the wrong pitch will render your chain useless. You must match the pitch to your chainsaw’s sprocket and bar. Incorrect pitch matching can ruin the sprocket and bar.

Chain Gauge: The Thickness of the Drive Links

The gauge refers to the thickness of the drive links, the parts of the chain that fit into the groove of the chainsaw bar. It’s measured in thousandths of an inch. Common gauges are .050″ and .058″.

Why it matters for cost: Again, the gauge must match the groove width of your chainsaw bar. An incorrect gauge will either bind in the bar or be too loose, leading to poor cutting performance and premature wear.

Drive Links: The Teeth That Power the Chain

Drive links are the small teeth that fit into the chainsaw bar groove. The number of drive links determines the length of the chain needed for your particular bar.

Why it matters for cost: Chains are sold by the number of drive links. Knowing the correct number ensures you buy the right size chain the first time, preventing unnecessary returns or wasted purchases.

Chain Types: From Aggressive to Low-Vibration

Chains come in various designs, each suited for different cutting tasks. Common types include:

Full Chisel: These chains have square-cornered teeth for fast, efficient cutting in clean wood. They are more aggressive but require more frequent sharpening.
Semi-Chisel: These chains have rounded corners, making them more durable and forgiving in dirty or knotty wood. They are a good all-around choice.
Low-Profile (Micro-Chisel): These chains have smaller teeth and a lower kickback risk, making them suitable for beginners or occasional users.
Why it matters for cost: Choosing the right chain type for your cutting needs can extend the chain’s lifespan and improve cutting efficiency. For example, using a full chisel chain in dirty wood will dull it quickly, requiring more frequent sharpening or replacement.

Tip #1: Know Your Numbers: Identifying the Correct Replacement Chain

This is the most critical step. Buying the wrong chain is like putting the wrong size tires on your car – it simply won’t work. Here’s how to ensure you get the right replacement.

Locating the Information on Your Existing Chain or Chainsaw

Check the Chainsaw Bar: Most chainsaw bars have the pitch, gauge, and number of drive links stamped directly on them. Look closely near the mounting end of the bar. Sometimes this information is etched and can be difficult to see, so make sure the bar is clean.
Consult the Chainsaw Owner’s Manual: Your owner’s manual is a treasure trove of information. It will specify the recommended chain types and sizes for your Poulan Pro 18″ chainsaw model.
Examine the Old Chain (If Available): If you still have the old chain, look for markings on the drive links or the chain itself. Sometimes, manufacturers stamp the pitch and gauge on the chain.
Online Resources: Poulan Pro’s website and other online retailers often have chain selection guides where you can enter your chainsaw model to find the correct chain specifications.

Deciphering the Numbers: Pitch, Gauge, and Drive Links

Let’s say you find the following information on your chainsaw bar: “.325 .050 72 DL.” This translates to:

.325: Pitch is .325 inches.
.050: Gauge is .050 inches.
72 DL: 72 Drive Links.

Cross-Referencing with Retailers: Avoiding Compatibility Issues

Once you have these numbers, cross-reference them with online retailers or your local hardware store. Many retailers have chain finders where you can input these specifications to find compatible chains. Always double-check the information before making a purchase.

Beware of Generic Chains: While generic chains can be cheaper, they may not always meet the quality standards of name-brand chains. This can lead to premature wear and poor cutting performance.
Read Customer Reviews: Before buying a chain online, read customer reviews to see what other users have experienced with that particular chain.

Cost Implications: Buying the wrong chain is a complete waste of money. A decent quality 18″ chainsaw chain can cost anywhere from $20 to $40. By taking the time to identify the correct chain, you can avoid the cost of returning the wrong chain and buying the right one.

Personal Anecdote: I once made the mistake of assuming that all 18″ chains were the same. I bought a chain that was the wrong gauge, and it wouldn’t even fit on the bar. I ended up having to return it and order the correct one, wasting time and gas. Learn from my mistake!

Tip #2: Choosing the Right Chain Type: Matching Performance to Your Needs

As mentioned earlier, chains come in various designs. Selecting the right type for your cutting tasks can significantly impact performance, chain lifespan, and safety.

Full Chisel Chains: Speed and Efficiency for Clean Wood

Full chisel chains are designed for speed and efficiency. Their square-cornered teeth slice through clean wood with ease.

Pros: Fastest cutting speed, ideal for felling trees and bucking logs in clean conditions.
Cons: Dull quickly in dirty or knotty wood, higher kickback risk, require more frequent sharpening.
Cost Considerations: While full chisel chains may cost slightly more upfront, their faster cutting speed can save you time and fuel in the long run. However, the need for more frequent sharpening can increase maintenance costs.

Semi-Chisel Chains: Durability and Versatility for Mixed Conditions

Semi-chisel chains are a good all-around choice for users who encounter a variety of cutting conditions. Their rounded corners make them more durable and forgiving in dirty or knotty wood.

Pros: Good balance of cutting speed and durability, more resistant to dulling in dirty conditions, lower kickback risk than full chisel chains.
Cons: Slower cutting speed than full chisel chains, may require more force to cut through large logs.
Cost Considerations: Semi-chisel chains are generally less expensive than full chisel chains. Their durability and resistance to dulling can reduce maintenance costs and extend chain lifespan.

Low-Profile (Micro-Chisel) Chains: Safety and Ease of Use for Beginners

Low-profile chains are designed with safety in mind. Their smaller teeth and lower kickback risk make them suitable for beginners or occasional users.

Pros: Lowest kickback risk, easy to use, suitable for pruning and light cutting tasks.
Cons: Slowest cutting speed, not ideal for felling large trees or bucking large logs.
Cost Considerations: Low-profile chains are typically the least expensive option. Their ease of use and low kickback risk can reduce the risk of accidents and injuries, potentially saving on medical costs.

Hardwood vs. Softwood Considerations: Adapting to the Wood Type

The type of wood you’re cutting also plays a role in chain selection. Hardwoods like oak and maple require more durable chains, while softwoods like pine and fir can be cut with faster, more aggressive chains.

Hardwood: Semi-chisel or full chisel chains with hardened cutters are recommended for hardwoods.
Softwood: Full chisel chains can be used for softwood, but semi-chisel chains may be a better choice if the wood is dirty or knotty.

Cost Implications: Choosing the wrong chain type for the wood you’re cutting can lead to premature wear and poor cutting performance. This can increase the frequency of chain replacements and the cost of sharpening. For instance, if you’re consistently cutting hardwoods, investing in a chain specifically designed for this purpose can save you money in the long run by reducing wear and tear.

Data Point: According to a study by the U.S. Forest Service, using the correct chain type for the wood being cut can increase chain lifespan by up to 25%.

Tip #3: Mastering the Installation Process: Avoiding Costly Mistakes

Step-by-Step Guide to Chainsaw Chain Installation

Safety First: Always wear gloves and safety glasses when handling a chainsaw chain. Disconnect the spark plug wire to prevent accidental starting.
Loosen the Bar: Loosen the bar nuts on the side of the chainsaw to allow the bar to move freely.
Position the Chain: Place the chain around the sprocket and into the groove of the bar. Make sure the cutting edges of the teeth are facing forward in the direction of chain rotation.
Adjust the Tension: Use the tensioning screw to adjust the chain tension. The chain should be snug against the bar but still able to be pulled around by hand.
Tighten the Bar Nuts: Once the tension is correct, tighten the bar nuts securely.
Check the Tension Again: After tightening the bar nuts, check the chain tension again to make sure it hasn’t changed.

Common Installation Mistakes and How to Avoid Them

Incorrect Chain Direction: Make sure the cutting edges of the teeth are facing forward. Installing the chain backward will prevent it from cutting.
Over-Tightening the Chain: Over-tightening the chain can cause it to bind on the bar and wear out prematurely.
Under-Tightening the Chain: Under-tightening the chain can cause it to come off the bar, which is dangerous and can damage the chainsaw.
Forgetting to Tighten the Bar Nuts: Forgetting to tighten the bar nuts can cause the bar to come loose, which can also be dangerous.

Ensuring Proper Chain Tension: The Key to Longevity

Proper chain tension is essential for chain longevity and safe operation. Here’s how to check and adjust the chain tension:

Check the Tension Regularly: Check the chain tension before each use and after every few cuts.
Adjust the Tension When Necessary: Adjust the tension if the chain is too loose or too tight.
Use the Tensioning Screw: Use the tensioning screw to adjust the chain tension.
The “Pull-Around” Test: A properly tensioned chain should be snug against the bar but still able to be pulled around by hand.

Cost Implications: Incorrect chain installation can lead to chain damage, bar damage, and even chainsaw damage. Replacing a chainsaw bar can cost anywhere from $30 to $60, while repairing a damaged chainsaw can cost even more. By taking the time to install the chain correctly, you can avoid these costly repairs.

Personal Anecdote: I once saw a guy who installed his chain backward. He spent an hour trying to cut a log before he realized what he had done. He not only wasted a lot of time and energy, but he also dulled the chain significantly.

Tip #4: Sharpening Your Chain: Extending Lifespan and Saving Money

A sharp chain is a safe chain. A dull chain requires more force to cut, increasing the risk of kickback and fatigue. Sharpening your chain regularly will not only improve cutting performance but also extend the chain’s lifespan and save you money on replacements.
