Tool Maintenance

If a tool damaged or not set correctly then at best it will not work properly and at worst it could be dangerous to use! Knowing how to set up, maintain and report faults with tools is important in the workshop, this will improve the quality of your work and make sure you and your colleagues stay safe. Throughout the course you will need to demonstrate you can do these things as you complete your work. For your exam you will need to show that you have good knowledge and understanding of:

  • Reporting faults and fault reporting systems

  • General condition before, during and after use

  • Position and condition of guards

  • Position and security of cutting tools on machine tools

  • Secure holding techniques

Before using any tool...

Does it look right?

Before using any tool you need to check that it is in the right condition to be used. In some instances if the tool is not set up right then it will just do a bad job, in other cases it could be dangerous. Below are some examples of the things you should look for before using a tool:

Sharpness.

A sharp too is a safe tool, blunt tools require more force to operate so check the tool is sharp whether it be a saw, scribe or lathe tool. If it isn't, don't use it, get it fixed.

Visible damage.

If the tool has been damaged if might be dangerous to use so always check first. Some examples may include:

  • A chipped or worn cutting surface on a lathe tool will mean the tool won't cut properly leading to overheating and a poor surface finish.

  • A chipped hammer is very dangerous, this can be a sign of internal cracks and the whole head could shatter into pieces

  • Mushroomed ends of cold chisels and other struck tools can splinter and lacerate the hand of the user#

  • A bent tool is dangerous to use especially if you need to strike it during use. When struck it will be forced at an angle and may fly out of control.

Loose parts.

Loose parts of tools mean that bits may fall off during use. A wobbly hammer head may come loose mid strike sending the head across the room.

Guards

Never use a tool without the guards in place. If they are there then you must use them for your own safety and the safety of others in the workshop. Simple. End of discussion.

There may be times when guards need to be adjusted for particular jobs. If this needs to be done then you MUST get the teacher to assist.

Machine Cutting Tools

These must be securely mounted in the machine and checked before the machine is turned on. Tools should also be checked for damage and sharpened if needed. If in doubt speak to your teacher

Reporting Faults

Reporting faults is very important. If you find a tool or machine which looks damaged, or if you damage one during use, tell the teacher! Most damage and faults occur due to normal wear and tear, accidents can also happen so always report them; if faults aren't fixed then they could injure someone else.
