DeWalt DHS790AB Problems and Solutions

some common issues and problems with the DeWalt DHS790AB and their solutions:

• The saw won't start. This is usually caused by a problem with the power cord, the switch, or the trigger. To troubleshoot, check the power cord for any damage. If the power cord is in good condition, check the switch and the trigger. If the switch and the trigger are working properly, then the saw may need to be serviced.
• The saw cuts unevenly. This is usually caused by a dull blade. To sharpen the blade, use a sharpening stone or a power sharpener. If the blade is not the problem, then the saw may need to be aligned.
• The saw makes a loud noise. This is usually caused by a loose blade or a bearing that needs to be replaced. To tighten the blade, use a wrench to turn the blade nut clockwise. If the blade is tight, then the bearing may need to be replaced.
• The saw vibrates excessively. This is usually caused by a loose blade or a bent arbor. To tighten the blade, use a wrench to turn the blade nut clockwise. If the blade is tight and the saw is still vibrating, then the arbor may be bent.
• The saw overheats. This is usually caused by prolonged use or by using the saw in a dusty environment. To prevent the saw from overheating, allow it to cool down for a few minutes after each use. If the saw is overheating even after allowing it to cool down, then you may need to service the saw.

Here are some additional tips from experts on how to avoid common problems with the DeWalt DHS790AB:

• Always use the correct blade for the material you are cutting. Using the wrong blade can dull the blade quickly and can also cause the saw to vibrate excessively.
• Keep the blade sharp. A sharp blade will cut more smoothly and evenly, and it will also last longer.
• Lubricate the saw regularly. This will help to prevent the saw from overheating and will also extend the life of the saw's components.
• Store the saw in a cool, dry place. This will help to prevent the saw from rusting and will also extend its lifespan.

By following these tips, you can help to ensure that your DeWalt DHS790AB saw will last for many years to come.
