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.
- 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!
