When working with a jointer, or any woodworking tool for that matter, prioritizing your safety is paramount. This starts with the gear you wear. This isn’t just a recommendation; it’s a fundamental practice for anyone stepping into a woodworking shop.

First and foremost, protect your eyes. Wood chips and sawdust are inevitable, but eye injuries don’t have to be. Safety glasses or goggles are non-negotiable. They shield your eyes from flying debris that can cause serious harm. For even better protection, consider using face shields, especially when you’re working on tasks that generate a lot of dust and chips.

Hearing protection is another critical piece of safety gear. Jointers, like many woodworking machines, are loud. Prolonged exposure to this noise can lead to hearing loss over time. Use earplugs or earmuffs every time you turn on your jointer. It’s a simple step that can have a significant impact on your long-term health.

Lastly, be mindful of what you wear. Loose clothing, jewelry, or anything that dangles can easily get caught in moving parts, leading to severe injuries. Opt for fitted clothes and keep sleeves short or tightly rolled up. Remove all jewelry before starting your work. This includes rings, bracelets, necklaces, and anything else that could potentially catch on the machine.

1) Use Push Blocks


Utilizing push blocks is a fundamental safety practice that cannot be overstated when working with a jointer. They are specifically designed to keep your hands safely away from the cutterhead, significantly reducing the risk of accidents and injuries.

Push blocks provide several key advantages for woodworkers. Firstly, they offer a secure grip on the workpiece, allowing for stable and controlled movement across the jointer’s blades. This stability is crucial for achieving smooth, even cuts and maintaining consistent pressure throughout the jointing process.

One of the primary benefits of push blocks is their ability to apply even pressure across the surface of the material. This is especially important when face jointing, as it helps ensure a flat, uniform finish. The non-slip surface on the bottom of most push blocks grips the workpiece firmly, providing precise control and minimizing the risk of the wood kicking back or slipping.

Moreover, push blocks are designed with the user’s safety in mind. They allow woodworkers to keep their hands at a safe distance from the fast-spinning blades of the jointer. By effectively extending your reach, push blocks eliminate the need to place your fingers anywhere near the danger zone.

2) Set the Correct Cutting Depth

Setting the correct cutting depth on your jointer is a crucial step that significantly impacts both the safety and quality of your woodworking projects. A common and wise tip among woodworking professionals is to take small bites out of the wood rather than trying to remove too much material in a single pass. Generally, it’s recommended to set the cutting depth to no more than 1/16” at a time.

This approach does more than just protect the jointer’s blades from unnecessary wear and tear; it also reduces the risk of kickback, a dangerous situation where the wood is thrown back toward the operator at high speed. By removing smaller amounts of material with each pass, you maintain better control over the workpiece, leading to safer and more predictable outcomes.

Additionally, setting the jointer to a shallow cutting depth helps achieve smoother cuts. It allows for the gradual removal of material, which is particularly beneficial when dealing with hardwoods or pieces that have irregularities, such as knots or varying grain directions. This methodical approach ensures that the final surface is flat and smooth, requiring less sanding and preparation for finishing.

To adjust the cutting depth, you typically lower the infeed table to the desired height below the outfeed table. This setting determines how much material will be removed with each pass over the cutterhead. It’s important to make these adjustments carefully and to always double-check the depth before starting your work.

3) Keep the Jointer Beds Waxed

Applying paste wax to the beds of your jointer ensures that the wood glides smoothly over the surface, which is essential for both safety and the quality of your work.

When the jointer beds are not properly maintained, friction can increase between the wood and the metal, making it harder to feed the workpiece evenly and smoothly. This not only makes the job more physically demanding but also increases the risk of inaccuracies in your cuts and can even lead to dangerous situations like kickback.

To apply paste wax, first ensure that the jointer beds are clean and free of any sawdust, resin, or other debris. Apply a small amount of paste wax with a clean, lint-free cloth, spreading it evenly over the entire surface of the infeed and outfeed tables. After the wax has had a few minutes to dry, buff it to a smooth, shiny finish with another clean cloth. This will leave the beds slick and ready for your next project.

4) Maintain Proper Workpiece Control

Maintaining proper control over the workpiece is a critical aspect of safe and effective jointer use. This involves securely holding and guiding the wood through the jointer to ensure accurate and smooth cuts, while also minimizing the risk of accidents. The emphasis on this practice comes from its direct impact on both the quality of your work and your safety.

Secure control of the workpiece helps prevent kickback, a dangerous occurrence where the wood is forcefully ejected back towards the operator, potentially causing injury. It also reduces the likelihood of the wood making unintended contact with the cutterhead, which can result in damage to both the workpiece and the machine, as well as pose a significant risk to the operator.

To achieve proper workpiece control, it’s essential to use both hands to guide the wood, applying steady pressure and keeping the workpiece flat against the jointer table and fence. This ensures that the cuts are uniform and that the wood travels straight through the cutterhead. For longer or wider pieces, using outfeed supports can help maintain control and prevent the wood from tipping or veering off course.

Avoiding awkward positions while operating the jointer is equally important. Standing in a stable, balanced position, with your body to the side of the cutterhead path, allows you to maintain control without placing yourself directly behind the workpiece. This positioning not only facilitates better control but also reduces the risk of being struck by the wood in the event of kickback.

Furthermore, always be mindful of where your hands are in relation to the cutterhead. Push sticks and push blocks should be used whenever your hands would otherwise be close to the cutting action, providing a safe means to control the workpiece without putting your fingers at risk.

5) Always Use the Blade Guard

The blade guard on a jointer is a critical safety feature designed to minimize exposure to the cutterhead, significantly reducing the risk of accidental injury. It acts as a physical barrier between the operator and the sharp blades, ensuring that during normal operation, there’s less chance of fingers or hands coming into contact with the moving parts. The importance of always using the blade guard cannot be overstressed; it should be in place and properly adjusted for every operation.

When setting up your jointer for a task, the first step should always be to check that the blade guard is functioning correctly. It should move freely, covering the blades automatically when the workpiece is not in contact with the cutterhead. Before starting the machine, verify that the guard returns to its protective position over the blades. This simple check can be the difference between a safe work environment and a dangerous accident.

In addition to protecting the operator from direct contact with the blades, the blade guard also helps to control the ejection of chips and sawdust, directing them away from the user and reducing the risk of these materials causing distractions or visibility issues that could lead to accidents.

It’s worth noting that there might be specific operations where the blade guard needs to be temporarily removed, such as when performing certain types of cuts or adjustments. In these cases, it’s crucial to follow the manufacturer’s instructions carefully and to replace the guard as soon as the task is completed. Never operate the jointer without the blade guard in place unless it is absolutely necessary, and even then, take extra precautions to ensure your safety.

6) Check and Maintain the Jointer Regularly

Regularly checking and maintaining your jointer is essential for both safety and the quality of your woodworking projects. This routine should include checks for the sharpness of the blades, the cleanliness of the machine, and its proper setup before each use. These maintenance tasks are commonly advised because they directly impact the jointer’s performance and the operator’s safety.

Sharp blades are crucial for efficient and clean cuts. Dull blades can lead to rough finishes, require more effort to push the workpiece through, and increase the risk of kickback. Regularly inspect the blades for dullness or damage, and sharpen or replace them as needed. Keeping the blades sharp ensures that the jointer operates smoothly and reduces the physical strain on both the machine and the woodworker.

The cleanliness of the jointer cannot be overlooked. Sawdust and debris can accumulate on the machine, interfering with its operation and potentially leading to safety hazards. Before and after each use, clean the jointer beds, fence, and cutterhead area. This not only helps to maintain the jointer’s efficiency but also prevents the buildup of materials that could catch on the workpiece or obscure the cutterhead.

Proper setup is another critical aspect of jointer maintenance. This includes ensuring that the infeed and outfeed tables are parallel, the fence is square to the tables, and the cutting depth is set appropriately for the task at hand. An improperly set up jointer can produce inaccurate cuts and pose a safety risk to the operator. Take the time to check these settings before starting your work, making adjustments as necessary.

7) Understand the Material You’re Working With

Understanding the material you’re working with is crucial when using a jointer. Knowing when this tool is the right choice for the job and recognizing the limitations based on the thickness and length of the material is a key piece of advice that’s often repeated by woodworking experts. This knowledge not only ensures the safety of the operator but also protects the integrity of the workpiece and the jointer itself.

A jointer excels at flattening the faces and squaring the edges of boards, making it an essential tool for preparing rough lumber. However, it’s important to be aware of the size limitations for materials that can be safely and effectively processed. Generally, very thin, short, or narrow pieces may not be suitable for jointing because they pose a higher risk of kickback and can be difficult to control during the operation.

For materials that are too small or too thin, alternative methods such as using a planer with a sled for face jointing or employing hand tools like planes may be more appropriate. These methods can offer greater control and safety for handling challenging pieces.

Additionally, understanding the wood’s grain direction and how it affects the jointing process is vital. Feeding the wood into the jointer against the grain can lead to tear-out, where chunks of wood are ripped away, leaving a rough surface. This not only ruins the aesthetics of the piece but can also be dangerous if it causes the woodworker to lose control of the workpiece. Always inspect the grain direction before jointing and adjust your approach accordingly.

8) Focus and Avoid Distractions

Staying focused on the task at hand and not allowing distractions is a key safety tip echoed across numerous woodworking articles and guides. When operating a jointer, or any power tool for that matter, maintaining undivided attention is crucial for both the quality of the work and the safety of the woodworker. The jointer’s fast-moving blades require respect and vigilance to avoid accidents, and even a momentary lapse in concentration can lead to serious injury.

Distractions in the workshop can come from various sources—phones, conversations, or even one’s own wandering thoughts. It’s important to create a work environment that minimizes these distractions as much as possible. This might mean turning off your phone, working alone, or ensuring that you’re not rushed or trying to multitask while using the jointer.

Before starting the jointer, take a moment to clear your mind and focus solely on the task ahead. Plan out your actions, including how you will feed the workpiece through the machine, where your hands will be at all times, and what you’ll do once the cut is complete. This mental preparation helps ensure that you’re fully engaged with the operation and ready to react appropriately to any issues that may arise.

Additionally, recognizing signs of fatigue is vital. Tiredness can significantly impair your ability to concentrate and react quickly, increasing the likelihood of mistakes. If you feel yourself becoming fatigued, it’s time to take a break. Woodworking should never be a race against the clock. Safety and precision come from deliberate, focused actions.

9) Properly Adjust the Fence According to the Board Width

Properly adjusting the fence according to the board width is a crucial safety and operational tip for using a jointer, as highlighted in several woodworking guides. This practice minimizes exposure to the cutterhead, significantly reducing the risk of accidental contact while ensuring more precise and consistent results.

The fence on a jointer serves as a guide for the workpiece, helping to keep it straight and stable as it passes over the cutterhead. By adjusting the fence so that it closely matches the width of the board, you effectively limit the amount of the cutterhead that is exposed. This not only enhances safety by reducing the chance of your hands coming into contact with the blades but also improves the quality of the cut by providing better support to the workpiece.

For example, if you’re jointing a board that is four inches wide, you would adjust the fence so that only the portion of the cutterhead necessary for jointing that width is exposed. This adjustment is particularly important when working with narrower pieces, as it helps to prevent them from tilting or slipping during the jointing process.

Adjusting the fence is typically straightforward, involving loosening a locking mechanism, sliding the fence to the desired position, and then re-securing it. It’s important to ensure that the fence is both parallel to the cutterhead and perpendicular to the jointer table (unless you’re intentionally creating a beveled edge). Taking the time to make these adjustments can greatly improve the safety and effectiveness of your jointing operations.

10) Never Joint Too Short or Too Thin Pieces

A common guideline echoed across woodworking safety tips is to avoid jointing pieces that are too short or too thin. These types of workpieces pose a higher risk of kickback and injury due to their inability to be controlled safely during the jointing process. When a piece is too short, it becomes difficult to maintain adequate pressure and stability as it passes over the cutterhead, increasing the likelihood of the piece being caught by the blades and thrown back towards the operator. Similarly, thin pieces may flex or break under the pressure of the cut, leading to similar dangerous outcomes.

The specific dimensions considered too short or too thin can vary depending on the jointer’s design and the safety guidelines provided by the manufacturer. However, a general rule of thumb is to avoid jointing pieces shorter than 12 inches in length and thinner than 1/4 inch. These measurements provide a baseline for safety, but woodworkers should always exercise judgment and consider the capabilities of their specific equipment and their comfort level with the operation.

For workpieces that fall below these size thresholds, alternative methods should be considered. For example, using a planer with appropriate support jigs can safely thickness thin pieces, while a table saw with a crosscut sled or a handsaw can be used to square up shorter pieces. Additionally, when working with small or delicate pieces, hand planes and sanding can often achieve the desired results without the risks associated with power jointing.

11) Stand to the Side When Operating the Jointer

Standing to the side when operating the jointer, rather than directly behind the workpiece, is a critical safety measure designed to reduce the risk of injury from kickback. Kickback occurs when the jointer’s blades catch the wood improperly and propel it backward at high speed towards the operator. By positioning yourself to the side of the path of potential kickback, you significantly decrease the likelihood of being struck by the wood if it were to be ejected.

This stance not only prepares you to react more safely in the event of kickback but also provides a better vantage point for monitoring the progress of the workpiece as it passes over the cutterhead. It allows for a more natural movement with the wood, facilitating smoother, more controlled passes. Additionally, standing to the side helps maintain a consistent pressure and alignment with the fence, contributing to the accuracy and quality of the cut.

It’s important to adopt this position as a standard practice whenever using the jointer. Even if you’ve never experienced kickback, complacency can lead to dangerous situations. Woodworking machinery, while invaluable for the craft, demands respect and caution due to the inherent risks involved.
