1. Preparation before operation
1. The saw blade, shell and handle do not appear cracks or breakage.
2. The cable cord and plug are intact, and the switch operation is normal to ensure that the connection is correct and firm
Solid reliability.
3. The saw blade is installed firmly, the bolts are tightened, and the inner and outer chuck clamps the saw blade tightly. The flatness of the saw blade
The surface is perpendicular to the horizontal axis of the circular saw.
4. Check to ensure that the rotation of the movable protective cover is flexible, without deformation, and will not rub against the circular saw blade.
The connection is reliable and guarantees that it will not fall off during normal operation.
5. Check to ensure that the cut workpiece is firmly fixed.
Second, the operation precautions
1. The circular saw must be in a suspended position when starting to prevent the circular saw from jumping and touching when starting
The workpiece to be cut.
2. After the circular saw is started, it should be allowed to idle for a period of time to observe whether the saw blade is running normally.
Whether there is a phenomenon of left and right swing, whether the circular saw vibrates too much, and whether the noise is normal. 3. The electric circular saw must pay attention to the position of its cable during operation to prevent it from being cut
Electric shock or short circuit accident. The cable should be bypassed behind the body and then connected to the power supply, and the body should not be connected with the cable
Contact.
4. When the electric circular saw is cutting, the fingers must not approach the saw operator who rotates at high speed
The body must be kept at an appropriate distance from the device.
5. Do not use the circular saw in the position higher than the top of the head to prevent the circular saw or the cut workpiece from taking off
Fall causes accidents.
6. The new saw blade is generally flat, and when sawing, the sight distance needs to be selected within the range of 5?, 20?. 7. After the tool is started, it should run without load for a while, and check and confirm that the tool linkage is flexible and unimpeded.
When working, the afterburner should be balanced and not exerted too strongly.
8. It is strictly forbidden to use overload. During the operation, attention should be paid to the sound and temperature rise, and the abnormal should be stopped immediately
Examine. When the working time is too long, the temperature of the machine rises by more than 60?, or the soup hand may have a burning smell,
It should be stopped and cooled naturally before operation.
9. During the operation, do not touch the cutting tool with your hands, and find that it has a dull, broken and abnormal sound,
In the case, the inspection should be stopped immediately, and the power must be cut off before repairing or replacing accessories,
And wait for the saw blade to stop completely.
10. When the saw blade is dull and needs to be filed, the power should be turned off, the plug should be unplugged, and the saw blade should stop completely
In order to remove the saw blade to do business.
11. Turn off the power of the circular saw when the power is cut off, resting or leaving the work site. 12. After processing, the power should be turned off, and the equipment and the surrounding site should be cleaned.
