When setting the drill stop, is it necessary to have the air line attached to the drill motor?

When setting the drill stop, it is not necessary to have the air line attached to the drill motor because the setting process for the drill stop typically does not involve the operation of the drill itself. The drill stop is a mechanism that controls the depth of the hole being drilled, and this setting can often be done manually without the drill being powered on.

Having the air line disconnected allows for a safer environment to make adjustments, reducing the risk of any accidental activation of the drill motor while you are working on fine-tuning the drill's stop setting. Furthermore, it ensures that the settings can be made without the noise and potential hazards of the drill motor running.

This practice aligns with safety protocols, emphasizing that making adjustments or settings should be conducted with the machinery in a non-operational state to prevent any potential accidents or mishaps.
