Precautions for the Use of Electric Circular Saws

The electric circular saw is an electric tool that realizes sawing with the high-speed rotation of the circular saw blade. The following matters should be paid attention to when using an electric circular saw.

What you need to pay attention to before starting your electric circular saw

1. Cracked or deformed circular saw blades are not allowed.

2. The moving cover is used to protect the circular saw blade and also to prevent personal accidents. For the electric circular saw, it is strictly forbidden to remove the moving cover.

3. All mechanical and electrical connections should be firm and reliable without loosening. When the circular saw is running, there is no abnormal noise.

4. Before inserting the power plug of the circular saw into the socket, check whether the power switch is in the off position.

5. Do not wear loose clothing during operation, so as not to be caught in the circular saw blade and cause an accident. Make sure you are wearing protective equipment such as dust covers, goggles, and gloves.

6. When operating a circular saw, Anti-recoil measures and protective devices should be provided to prevent the objects being cut from rolling to both sides of the circular saw blade when sawing log materials.

Get the right blade for your electric circular saw

The circular saw blade is the working tool of the electric circular saw. Before use, the sawing path should be corrected, the sawtooth should be ground, and the sawtooth should be shifted to the left and right in turn. This will adjust the angle appropriately. After the circular saw blade is installed, check whether its rotation direction is consistent with the direction of the arrow marked on the moving cover. You cannot install a circular saw blade in reverse. The oblique tooth circular saw blade (longitudinal cutting type) is used for sawing longitudinal fiber wood, and the straight tooth circular saw blade (transverse type) is used for sawing wood that is orthogonal to the fiber direction. The teeth of the circular saw blade should be kept sharp.

Electric circular saws should pay attention when sawing

1. Before sawing the material, check whether the movable cover is flexible, whether the size of the saw blade guide is suitable for the circular saw blade used, and make the following adjustments. The distance between the saw blade guide and the circular saw blade ring gear within the cutting depth range should not exceed 5mm, and the distance between the saw blade guide and the highest point of the lower circular saw blade should not exceed 3mm.

2. After the electric circular saw is started, the sawing can only be started after the speed is stable. The advancing speed of the electric circular saw is determined by the technical performance parameters of the electric circular saw and the hardness of the wood. Generally, the propelling speed of medium hardwood (white pine) is 1m/min. In addition, pay attention to the direction of wood fibers when sawing, adjust the propulsion speed, and the thrust should not be too strong. After the electric circular saw is processed, the method of pressing the side plane of the circular saw blade shall not be used for braking.

3. When using an electric circular saw to longitudinally cut materials with a width of less than 80mm, a sliding bar or similar device should be installed beside the longitudinal baffle, so that the sawed workpiece can be thrown away in time.

4. In order to ensure that the saw seam of the electric circular saw is parallel to the edge of the wood, the longitudinal baffle installed on the bottom plate can be adjusted, and the edge of the translated wood is close to the baffle to guide the sawing. The width of the wood to be cut is read from the slide rule attached to the baffle.

Home improvement Beginners, the Top 5 most Cost-Effective Cordless Drill on Amazon!

Why do you need a electric drill? The main reason is to save effort and time. The torque of an adult man screwing a screwdriver can generally reach 5 Nm, which can be completely replaced by the most common electric screwdriver.

Safety Tips for Operating an Angle Grinder

Power tools are usually engaged in high-speed motion which can cause danger if precautions are not taken.

Although the chance of injury is minimized using a Hychika angle grinder with a triple safety design( safety switch, auxiliary handle, and wheel guard), there are still a few guidelines to follow in order to stay injury-free all the time.

  1. Disconnect from the power source (the battery pack from the power tool) before making any adjustments, changing accessories, or storing power tools. Inspect parts for misalignment, binding, or breakage.

2. When not in use, store the battery away from other metal objects like paper clips, coins, keys, nails, screws, etc,

3. The outside diameter and the thickness of your discs must be within the capacity rating of your power tool.

4. Threaded accessories must match the grinder spindle thread. Or else the power tool will run out of balance.

5. Wear protective equipment such as a face shield, safety goggles, or safety glasses to stop small abrasive work-piece fragments.

6. Hold the power tool by insulated gripping surfaces only in case the cutting accessory may contact hidden wires.

7. Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and lose control.

8. Maintain a firm grip on the power tool to resist kickback forces. Always use an auxiliary handle for maximum control.

9. Never place your hand near the rotating accessory.

10. Do not “jam” the cut-off wheel or apply excessive pressure on it.

11. Do not attempt to make an excessive depth of cut. Over-stressing the wheel increases the chance of wheel twisting or binding.

13. Do not position your body in line with the rotating wheel.

14. When the wheel is binding or the cut interrupted for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop.

15. Do not restart cutting in the workpiece.

16. Be extra careful when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring, etc.

17. Large workpieces tend to sag under their own weight. Supportive pads must be placed under the workpiece near the line of cut.

Be acknowledged of the above, and now you are ready to go!

Corded

The corded grinder felt truly in its element on metalworking project, handling cuts and grinds nicely. The use of a dual micro-switch prevents accidental start-up and provides better user protection during use.

Tips for Using a Cordless Mini Chainsaw

Limit cutting material to wood only

Never use a mini chainsaw for cutting any non-wood material, including plastic, masonry, or metal. Never cut a tree or branch with a diameter wider than the length of the mini chainsaw’s guide bar. 

Tension the Chain Properly

Make sure that the chain is properly tensioned on the guide bar. A loose chain may whip free or draw materials into it. A tight chain may not move at all or have a higher risk of breaking down during heavy-duty operations.

A thumb of rule: pull the chain to check the tightness of fitting. Let the upper side of the down chain bite loosely with the guide bar but leave no clearance when you pull the down chain with force.

Avoid kickback

Kickback results from the tip of the moving chainsaw being allowed to come into contact awkwardly with an object. The tip may bounce wildly backward and injure the worker.

The guide bar of the mini chainsaw should be 1-2 inches longer than the diameter of what you need to cut. Chainsaws with a top flap or low kickback have a lower risk of kickback incurred injury.

Sharpen the chain regularly

There’s no hard-and-fast rule on how often you need to sharpen your chainsaw, but many experts recommend doing it every time you need to refuel the tool.

Follow the dressing code

Do not wear loose-fitting clothing, dangling jewelry, or anything else that could become caught in the chain of the saw.

Avoid Touching the Chain, Even When Stationary

Chainsaws’ chains are very sharp. Even when the chain is not moving, it can severely lacerate the skin. Be sure to keep the cover on the saw when not in use or remove the battery so the machine doesn’t start at all.

Lubricate the chain in a timely manner

The oil lubricates the bar and chain, preventing premature wear and possible derailing of the chain. 

After the oil is applied, run the chainsaw for a few seconds until it is spread evenly onto the chain. While manual oiling may be a little tricky to handle, there are auto oiling options that distribute a consistent, steady flow of oil onto the chain. Check the oil tank to keep track of the oil level for a timely refill.
