2. Increased. Never trust a tool lifter. Most jacks are not strong enough to support the side or lengthways movement of a device, especially when the machine is on uneven ground. If you pull the tow bar bolt, you will not be able to move quickly. If your foot is under your tongue, it can crash. Keep your feet out of the way and wear "pointy shoes" around equipment.
3. The color has been removed. Harmful vapors can be produced if a torch heats paint during the soldering process. Always remove paint in and around the area to be heated or welded. Wear an approved breathing apparatus to avoid breathing dust. When removing paint with solvent or paint stripper, wash with soap and water before welding. After all combustible materials have been removed, wait 15 minutes. I know there is always a hurry to get a machine running, but a fire tends to give undesirable time to a "quick" repair.
4. Redesigned thumbtack. The replacement PTO push pin part that was used to secure the implement yoke to your tractor's PTO shaft may be hard to find because the push pin has been redesigned. Older American PTO locks (sometimes referred to as "obsolete") can be a safety hazard because the adjustment clip used to secure the padlock can easily get caught on clothing or fly off, loosening the tool transmission. Be careful with the PTO transmissions.
5. Freedom of movement of the front wheels. Use caution when changing the spacing on the front wheels of a tractor. Never insert your finger into the hole in the two-piece shaft to remove a cap screw. When removing a cap screw, the shaft halves can separate in a shear motion. A friend of mine tried to remove a head screw with his finger and the shaft moved. Use three fingers to tell this story.
6. Loose drawers. Be careful not to open too many drawers in your foldable tool box at once (like I did). When the box begins to open, each unlocked drawer will open one at a time. All you can do is walk away. Don't waste your drawers! Keep her locked up.
7. The amplifiers have gone crazy. Use caution when working with electrical cables on your device. Just because the meter reads 12 volts DC doesn't mean it can't burn the wires and start a fire. A small wire will read approximately 12 volts and a large battery wire will read approximately 12 volts. However, the larger cord can carry many more amps and the uncontrolled amps can easily start a fire. Low resistances and high currents are dangerous, especially if the cables are not protected by fuses. Remove, disconnect, or cover any exposed battery cables before starting work.
8. Beat the air. Have you ever been slapped by one of those long, pointed blowpipes? Shot! It's like a super fuel jet engine. Air guns that mount directly on the air hose and are only 5 inches long are very easy to use. However, if you are buying one of these lengths to blow out your tractor's radiators or cab, be careful. When you grab the lever, hold it in place. This thing is going to come and hit your forehead. The length of the blowgun gives this jet-propelled object more weight than your hand can support.
9. Contact fire. I know the harness pins in a harness connection need to be cleaned. But be careful. I can tell you that the electronic compound cleaner can be highly flammable. After spraying the cleaner, use a plastic or nylon brush to clean the corroded pins. I used a steel wire brush once and the cleaner caught fire when I raked the plug.
10. Never ... never. Never weld near a battery, especially when it is being charged. The battery can explode. I have acid stains on my shop wall to prove this.
