Prevention of Hand Tool Injuries

 Compared with power tools, hand tools mainly rely on hands to twist or apply force to the tools. Most people are not trained before using hand tools, which leads to frequent accidental injuries. Every year, injuries caused by improper use of hand tools account for 7% to 8% of all accidental injuries. Therefore, Hand Tool Supplier recommends that you must understand their correct use methods, do good maintenance and management, and pay attention to use safety.

1.How to Use Hand Tools

Saw

① The saw blade should be selected correctly according to the hardness and thickness of the material to be processed; the tension of the saw blade should be appropriate and adjusted at any time according to the hand induction.

②The workpiece to be sawed should be clamped, and there should be no displacement and vibration during sawing; the sawing line should be close to the supporting point of the workpiece.

③When sawing, the saw bow should be straightened to prevent skewing, and the sawing should be stable.

④When sawing, when pushing the saw forward, your hands should be applied with proper force; when retreating the saw, you should lift the hand saw slightly without applying pressure. The amount of force should be determined according to the hardness of the workpiece to be cut, the greater the hardness, the greater the force, the less the hardness, the smaller.

⑤When installing or replacing a new saw blade, you must pay attention to ensure that the tooth tip of the saw blade is facing forward; after replacing the new blade in the middle of sawing, you should turn around and cut, and it is not advisable to continue to cut along the original saw; when the workpiece is about to be cut off, Use your hands to hold it, so as not to drop your feet.

Wrench

①The wrench of appropriate size should be selected according to the nature of the work.

②When using the adjustable wrench, force should be applied to the fixed side, never force to the movable side.

③If the opening of the wrench is worn or slipped during use, do not continue to use it to avoid slipping your hands.

④Do not use a wrench as a hammer to strike.

⑤Do not put a pipe on the end of the wrench to increase the torque of the wrench.

Pliers

①Pliers are only used to fasten, insert and remove various pins and nails, and to cut or tighten various wires.

②Pliers cannot be used to tighten or knock bolts or nuts.

③Do not tap or lengthen the handle of the pliers to increase the clamping or cutting power.

Do you really Understand Grease Gun?

 A grease gun is commonly used for lubrication in workshops and garages. The purpose of a grease gun is to apply lubricant through a hole to a specific point, usually from grease boxes to grease fittings.

1.Four Types Of Grease Gun

Manually driven, the grease is removed from the hole by manually shaking the trigger mechanism of the spray gun, which applies the pressure to the spring mechanism behind the lubricant, thus forcing the grease through the hole.

Hand-powered, without a trigger mechanism, the grease is pushed into the hole by the back pressure generated by the gun built to push the grease gun into the hole,  so that the piston slides through the tool body to pump the grease out of the hole.

Pneumatic, Where compressed air is guided through a hose to the spray gun, and air pressure is used to force grease through the holes.

Electric, driven by an electric motor high-pressure grease pump. These are usually battery-powered for portability.

2.The Correct Use Method of Grease Gun

Unscrew the grease gun head to separate the grease gun head from the barrel.

Dip the opening part of the gun barrel into the barrel of butter. When it is approximately 30 mm deep, hold the barrel tightly with one hand, and pull the driven handle at the tail of the barrel backward with the other hand to suck the butter into the barrel. 3. Install the oil gun head, press the locking piece at the end of the barrel, and push the driven handle into the barrel.

3.Matters needing attention of Grease Gun

This oil-loading gun is likely to have air left in it, which will cause the butter to fail. At this time, pull the driven handle at the end of the barrel to the end, and then press the vent with one hand, and press the button at the end of the barrel with the other. Lock the piece, and at the same time push the slave handle into the gun barrel to exhaust the air in the gun. This method is called the exhaust method for short. Another way of exhausting is when there is no exhaust valve on the grease gun, you can push the driven handle in the barrel several times, loosen the nozzle slightly to exhaust, and then tighten the nozzle.

4. Advantages of Grease Gun

Waste prevention. Proper lubrication is essential for any vehicle or machine, and the grease gun is an effective delivery system for grease, oil, or lubricating oil. Because you can calculate exactly how many trips are allocated per trip, you can prevent the overflow of wasted products.

Long product life. Not only will properly lubricate your vehicle for a long and smooth ride but also a properly maintained filling gun will stand the test of time. This feature is especially useful if you are a regular grease-using hobby or professional mechanic.

Better saturation. Many delivery systems spray oil over the entire area of the component. The grease gun allows you to transfer grease with higher accuracy so that the parts are properly soaked.

Accuracy and speed. grease guns help to collect grease quickly and accurately. This is especially useful if you are a shopkeeper, where every minute counts. With a grease gun, you can fill the entire bottom of the car in about a minute, which is much faster than using a push tank or other delivery system.

To save money. Because the grease gun is very accurate, you can save a lot of money on additional products and parts. Properly lubricated parts will last much longer than poorly maintained parts, saving you money on replacement costs.

How to Use the Glue Gun?

 A Caulking gun is a tool to hold a tube or box filled with the material used to seal gaps and faults in a home. Caulking materials can be made of silicone or latex and are used to bond various materials such as metals, glass, wood, and ceramics. The caulking material is usually placed in the pipe. You will need a caulking gun to remove the caulking agent from the tube. The gun not only helps you adjust how many caulks are released at a time but also makes the caulks appear exactly where you want them to.

The main points for attention when selecting a glue gun

Check the lever.

Squeeze the manual trigger with the manual caulking gun and push a lever into the back of the caulking agent tube, which in turn pushes the caulking agent out of the tip of the tube. There are two main types of guns with slightly different performance.

Ratchet: A seamed gun with a ratchet rod (a sawtooth rod that is "caught" in each hand) is inexpensive and suitable for light duty. The biggest problem with the ratchet rod is that the sealant seeps until you twist the end of the rod and pull it back to release pressure. This can cause confusion and lead to a waste of sealant.

Smooth slider: After applying the sealant with a smooth slider caulking gun (often advertised as "drip-free"), press the thumb lever to release the pressure on the sealant.

The application method of China Caulking Gun.

Use your thumb to press the release on the back of the gun and release the plunger on the back.

Fully pull back the plunger. Place the pipe into the spray gun with the nozzle in front.

Push the plunger firmly into the back of the tube and remove the thumb. The gun is loaded.

Cut the tip of the cartridge to match the size of the gap to be filled.

Drive a nail or tack through the hole to Pierce any internal seal.

Hold the gun at a 45-degree Angle along the gap to be sealed.

Squeeze the handle of the gun or trigger it slowly while pulling the gun towards you. When you can no longer squeeze the handle, release it. It will automatically bounce back. When it is in its original position, you can squeeze again. How hard you squeeze the trigger and how fast you move the gun will determine how much caulking is applied to each position. Keep in mind that there are more gaps at the end of each squeeze.

When finished, you can smooth out the gap with your finger.
