When operating a planer, it is important to avoid wearing any item that can potentially get caught in the machine or cause injury. Lapel pins, finger rings, long earrings, and necklaces can all pose a risk while operating the planer. Therefore, all of the above items should not be worn when using the planer.

Before operating a planer, articles of clothing such as ties and coats should be removed. This is because loose clothing can get caught in the blades of the planer, causing serious injury. It is important to ensure that there are no loose or hanging items that could potentially get entangled in the machinery. Therefore, removing clothing items before operating the planer is the safest and most appropriate action to take.

All of the options listed can potentially lead to serious accidents while using a planer. "Horseplay" refers to engaging in playful or reckless behavior that can distract or endanger oneself or others. Carrying on a conversation with a friend can divert attention away from operating the planer safely. Standing behind a board as it travels through the machine is extremely dangerous as it can result in severe injuries if the board kicks back or gets pulled in forcefully. Therefore, all of these actions can cause serious accidents while using a planer.

Industrial quality protective equipment should be worn for the protection of eyes, ears, and feet. This is because working in an industrial environment can expose individuals to various hazards such as flying debris, loud noises, and heavy machinery. Wearing protective equipment like safety glasses, earplugs, and steel-toed boots can help prevent injuries and ensure the safety of workers. Therefore, the correct answer is "all of the above".

Before starting the planer, it is important to ensure that all guards are in place and securely fastened to ensure safety. Additionally, clearing the area of scraps, sawdust, oil, or grease is necessary to prevent any accidents or damage to the machine. Furthermore, clearing the machine and table area of chips, tools, or other matter is essential to maintain a clean and organized workspace. Therefore, all of the above actions should be taken before starting the planer.

The correct answer is 1 because the question asks how many boards can be fed safely through the planer at one time. This implies that only one board can be fed at a time to ensure safety.

When leaving the planer work area, it is important to turn the machine off and wait until all moving parts stop before leaving. This is necessary to ensure safety and prevent any accidents or injuries that may occur if someone were to leave while the machine is still running. Waiting for the machine to completely stop ensures that there is no risk of getting caught in any moving parts or being in the way of any potential hazards.

The depth of cut refers to the distance that the cutting tool penetrates into the material being cut. It is influenced by various factors, including the width of the lumber, rate of feed, and kind of lumber. The width of the lumber affects the amount of material being removed in each pass, the rate of feed determines the speed at which the tool moves through the material, and the kind of lumber can impact the hardness and density, which can affect the cutting depth. Therefore, all of these factors play a role in determining the depth of cut.

The correct answer is "all of the above". This means that all of the given options are reasons why one should never attempt to surface lumber. If the lumber is shorter than the distance between the infeed and outfeed rollers, it may not be properly supported and could cause damage to the machine or the lumber itself. If the lumber is less than 3/8 inch thick, it may not be stable enough to be surfaced. If the lumber is cracked, it may not be structurally sound and could cause issues during the surfacing process.

The maximum amount of cut recommended for a thickness planer is 1/16 inch. This means that when using a thickness planer, it is recommended to remove a maximum of 1/16 inch of material in a single pass. Removing more than this amount can put excessive strain on the machine and may result in poor quality cuts or damage to the planer. It is important to follow this recommendation to ensure safe and efficient operation of the thickness planer.

Lumber should be fed into the planer with the grain. This is because feeding the lumber with the grain allows for a smoother and more consistent cut. Feeding against the grain can result in tear-out and rough surfaces. Feeding on edge or only with the operator standing within 18" of the planer are not relevant to the feeding direction of the lumber.

Painted stock should never be run through the planer because the planer blades can damage the paint and cause it to chip or peel off, resulting in an uneven and unsightly finish. Additionally, the paint residue can clog the planer blades, reducing their effectiveness and potentially causing damage to the machine. Therefore, it is best to avoid running painted stock through the planer to ensure a smooth and consistent finish.

The purpose of the helper when using the planer is to support and move with the stock as it comes through the planer. This ensures that the stock remains stable and does not shift or wobble during the planing process. By moving with the stock, the helper can also help guide it through the planer, ensuring a smooth and even cut.

If the lumber being planed stops part way through the cut, it is important to stop the planer and remove and discard the board. Continuing to operate the planer with a stuck board can cause damage to the machine and potentially cause injury. It is necessary to stop the planer and safely remove the board before continuing with any adjustments or further cutting.

When using a planer, it is important to never stand or walk directly behind it while it is in operation because knots may fly out and hit you. This can pose a serious safety hazard as knots can be ejected with force and cause injury. It is crucial to always maintain a safe distance and position yourself in a way that minimizes the risk of being hit by flying debris.
