Handling a chainsaw requires meticulous attention to safety and proper techniques. One crucial aspect of chainsaw operation is ensuring the correct installation of the chain. A loose or improperly placed chain can lead to hazardous situations, such as kickbacks or chain derailment. Therefore, it’s essential to master the art of putting a chain on a chainsaw effectively and safely. This guide will provide step-by-step instructions to help you tackle this task confidently.

Before embarking on the chain installation process, gather your necessary tools and materials. You will need a pair of work gloves for protection, a screwdriver or wrench for tensioning the chain, and a file or sharpening stone for preparing the chain. Additionally, ensure your chainsaw is unplugged or the fuel valve is closed to prevent accidental starting during the procedure. Moreover, placing the chainsaw on a stable surface or workbench will provide a safe and convenient working environment.

Now that you have prepared your chainsaw and gathered the necessary tools, let’s delve into the step-by-step process of putting a chain on a chainsaw. First, locate the guide bar and the drive sprocket on your chainsaw. The guide bar is the long, flat metal rail that runs along the bottom of the chainsaw, while the drive sprocket is the gear at the end of the engine that drives the chain. Place the chain around the guide bar and the drive sprocket, ensuring that the cutting teeth are facing in the correct direction. The direction of the cutting teeth will vary depending on the specific chainsaw model, so it’s crucial to consult your chainsaw’s user manual for guidance.

Choosing the Right Chain

Selecting the appropriate chain for your chainsaw is crucial for optimal performance, safety, and longevity. Consider the following factors when making your choice:

Chain Pitch:

The chain pitch refers to the distance between three consecutive rivets on the chain. Common chainsaw pitches include 0.325″, 0.375″, and 0.404″. Choose a chain pitch that matches your chainsaw’s guide bar:

Guide Bar Length	Common Chain Pitches
Up to 16″	0.325″
16″ – 20″	0.375″
20″ and above	0.404″

Chain Gauge:

The chain gauge represents the thickness of the drive links. It must correspond to the width of the guide bar’s groove. Common chain gauges are 0.043″, 0.050″, and 0.058″. Ensure that both the chain and guide bar gauge values align:

Guide Bar Thickness	Chain Gauge
0.043″	0.043″
0.050″	0.050″
0.058″	0.058″

Chain Length:

The chain length is determined by the guide bar’s length. Match the number of drive links on the chain to the number of inches in the guide bar:

Guide Bar Length (inches)	Number of Drive Links
16″	50
18″	56
20″	62

Chain Type:

Chainsaws employ two primary chain types: semi-chisel and full-chisel. Semi-chisel chains are less aggressive but easier to maintain and suitable for occasional users. Full-chisel chains offer higher cutting efficiency but require more frequent sharpening and are recommended for experienced operators.

Measuring the Guide Bar Length

Determining the correct chainsaw chain size requires accurate measurement of the guide bar. Here’s a step-by-step guide to measure the guide bar length:

Step 1: Remove the Chain and Guide Bar

To begin, remove the existing chain and guide bar from the chainsaw, ensuring that the fingers or body are not near moving parts.

Step 2: Place the Guide Bar on a Flat Surface

Lay the guide bar flat on a stable surface, with the tip of the bar facing away from the user. Ensure the surface is level and provides adequate space for measurement.

Step 3: Measure from the Tip to the Drive Link End

Using a measuring tape or ruler, carefully measure the distance from the tip of the guide bar (where the chain would start) to the opposite end, where the drive link would engage with the sprocket. This measurement represents the guide bar length.

Step 4: Round Up to the Nearest Inch

Guide bar lengths are typically specified in inches. Once you have the measurement, round it up to the nearest whole inch. This value will be used to determine the correct chain length.

For example, if the measured length is 17.5 inches, round it up to 18 inches. Rounding up ensures that the chain is long enough to securely wrap around the guide bar and engage with the sprocket.

Installing the Chain

Installing the chain on a chainsaw is a straightforward but crucial task. It ensures the proper functioning and safety of the tool. To begin, follow these steps:

1. Gather the Necessary Tools

You will need the following:

Thread the chain around the guide bar’s tip and ensure a snug fit.

4. Adjust Chain Tension

Proper chain tension is essential for optimal cutting performance and safety. Use the wrench or socket set to adjust the tension until the chain is snug but not too tight. You should be able to pull the chain around the bar by hand with some resistance.

5. Lubricate the Chain

Chainsaw chains require regular lubrication to reduce friction and prolong their lifespan. Apply a chain lubricant to the chain at the manufacturer’s recommended intervals.

Tightening the Chain

Once the chain is placed on the chainsaw, it needs to be properly tightened. Tightening the chain is critical for the safety and performance of the chainsaw. Here are the steps to tighten the chain:

1. Hold the chainsaw by the rear handle, with the bar pointing away from you.

2. Locate the chain tension adjustment knob or screw, which is usually located on the side of the saw, below the guide bar.

3. Turn the adjustment knob or screw clockwise to tighten the chain. The chain should be tight enough so that it does not sag when you lift it off the ground, but not so tight that it binds when the saw is running.

4. To fine-tune the chain tension, follow these steps:

Step	Description
a.	Check the chain tension by pulling up on the chain with your fingers. It should be tight enough so that it does not sag more than 1/4 inch.
b.	If the chain is too loose, turn the adjustment knob or screw clockwise to tighten it.
c.	If the chain is too tight, turn the adjustment knob or screw counterclockwise to loosen it.
d.	Repeat steps a-c until the chain tension is correct.

5. Once the chain is properly tightened, tighten the bar nuts. These nuts are located on either side of the guide bar, and they help to hold the bar in place.

Lubricating the Chain

Lubricating the chain is essential to prevent wear and overheating. There are three main types of chain lubricants: oil, grease, and spray.

Oil is the most common type of chain lubricant and is typically applied with a brush or oil can. Grease is thicker than oil and provides longer-lasting lubrication, but it can be more difficult to apply. Spray lubricants are convenient to use, but they can be more expensive than oil or grease.

To lubricate the chain, first clean it with a degreaser. This will remove any dirt or debris that could clog the oiler. Next, apply a thin layer of lubricant to the chain. Be sure to cover all of the surfaces of the chain, including the links, rollers, and teeth. Finally, run the saw for a few minutes to distribute the lubricant.
