- Safe practices should be observed when working on any electronic circuit or equipment.
When using hand tools, always observe the following precautions:
1. Always use the proper tool for the job. Use the right type and size tool for each application.
2. When carrying tools, always keep the cutting edge down.
3. Keep hands clean when using tools. Avoid grease, dirt, or oil on hands when using any tool.
4. Clamp small pieces when using a hacksaw, screwdriver, or soldering iron.
5. Avoid using chisels and punches with mushroomed heads.
6. Never use a file without a handle.
7. Never use plastic-handled tools near an open flame.
8. Keep metal rules clear of electrical circuits.
9. Disconnect all electrical devices by pulling directly on the plug, never the cord.
10. When cutting wire, always cut one wire at a time to avoid damaging the cutting tool.
Power tools
Power tools
When handling the power tools, always observe the following precautions:
1. Ensure all power tools have grounded three-prong plugs or an insulated housing approved by UL (Underwriters Laboratories).
2. Make all adjustments to the machine before turning it on.
3. Double-check any special setups before applying power.
4. Keep all safety guards in proper position at all times.
5. Clean the work area before using a power tool and keep it clean.
6. Keep power tools clean, and put away them when they are not in use.
7. Avoid treating power tools roughly, dropping them, or hitting them against things.
8. Keep all power tools in good condition with regular maintenance.
9. When finished using a power tool in the workshop, find a safe place to set it down when working.
Getting what you pay for
Getting what you pay for
With tools, the old mantra ‘you get what you pay for’ is generally true. Good tools that are manufactured from the best materials and with the best quality fetch a premium price. Cheap tools are, well, cheap.
Two main drawbacks apply to cheap tools:
✓ They don’t last. The business end of a cheap tool wears out very quickly. For example, each time you cut a wire with a pair of cheap wire cutters, you ding the cutting blade a bit. Pretty soon, the cutters can barely cut through the wire.
✓ When cheap tools wear out, they tend to damage the materials you use them on. For example, tightening a screw with a badly worn screwdriver can strip the screw. Likewise, attempting to loosen a tight nut with a worn-out wrench can strip the nut. We do, however, endorse spending money on cheap tools to help you get started in this fascinating hobby as inexpensively as possible. You can start with cheap tools and replace them one by one with more expensive tools as your experience, confidence, love of the hobby and, crucially, your budget increase.
