Instructions for using the product:
• Remove the bracket from the packaging and check that all parts are present.
• Set the angle to the desired angle by moving the movable parts and securing them in the appropriate position.
• Place the square on the surface where you want to take measurements or mark an angle.
• Check that the angle is correctly adjusted and that it is horizontal using the built-in spirit level.
• Once you have reached the desired angle, mark it on the surface with a pencil or other suitable tool.
• After use, store the angle in a safe place.

Useful tips for work:
• Before use, check that all parts of the angle are properly attached and functioning properly.
• For the most accurate results, use a square on a flat surface.
• Check that the angle is correctly adjusted and horizontal using the built-in spirit level.
• When marking angles, use a pencil or other suitable tool that will ensure a clear and permanent marking.
• After use, store the angle grinder in a dry and safe place.
• Regularly check the condition of the angle and clean and maintain it as necessary.

Warnings:
• Before use, check that screws and moving parts are not loose.
• Do not use a deformed square as it may cause incorrect measurements.
• Do not use it as a lever or hammer.
• Be careful of your fingers when marking with a sharp pen.
• Store the square in a dry place and protect the measuring surfaces from impacts and scratches.

Same summary

The universal multi-purpose adjustable square 300mm is particularly suitable for users who want to cover a wide range of tasks with one measuring device - from marking right angles when assembling furniture to measuring and transferring arbitrary angles on larger elements. Due to the long measuring scale, the square is particularly useful when working with larger structures, fences or in assembly, where accurate marking on longer boards is important. However, for very small, detailed work, it may not be the most convenient due to its length. The adjustable function allows for greater flexibility, but it is important that the structure remains rigid enough for repeatable accuracy in work.

Answers to frequently asked questions

For what projects is the 300 mm angle length best suited?

The 300 mm length allows for comfortable and precise use in larger construction projects, fence installation, installation of longer wooden or metal elements, as well as in general carpentry and assembly work. For very small, interior work or furniture details, a shorter square is sometimes more convenient.

Is this protractor suitable for transferring and measuring different angles?

Yes, the square is adjustable, which means it is suitable for both checking squareness and transferring and marking other angles. It is recommended to ensure that the mechanism is well locked so that the angle does not change during work.

How important is the robustness of a square in everyday use?

Robust construction reduces the possibility of deformation and increases accuracy during repeated use, which is especially important on construction sites or during intensive work. Thinner or lighter versions are more sensitive in more demanding work.

Can I also use this square to mark and cut slanted lines?

Yes, the adjustable functionality is useful when marking slanted lines, which is practical when cutting or assembling various elements at an angle.

Is this angle grinder suitable for beginners in DIY projects?

Due to its easy adjustment and multifunctional use, the angle is suitable for both beginners and experienced users, as it allows multiple functions in one tool without the need to frequently change instruments.
