My thoughts:

Overall, the Makita GN900SE is a powerful and versatile circular saw that is perfect for a variety of tasks. The large blade and powerful motor make it easy to cut through even the toughest materials, and the laser guide helps you make straight, accurate cuts. The saw is also relatively lightweight and compact, making it easy to transport from job site to job site. However, the saw can be noisy when in use, and the blade guard can be difficult to remove. Overall, I think the Makita GN900SE is a great saw for the price, and I would definitely recommend it to anyone looking for a powerful and versatile circular saw.

Here are some additional thoughts on the Makita GN900SE:

• The laser guide is a very helpful feature, especially for making straight cuts. However, it can be difficult to see in bright sunlight.
• The dust blower is a nice addition, but it doesn't do a perfect job of keeping the work area clear. You'll still need to use a vacuum or broom to clean up after yourself.
• The saw is relatively lightweight and compact, but it's still not as portable as some other models. If you need a saw that you can easily carry with you, you may want to look at a different option.
• The saw is very powerful, but it can also be noisy. If you're sensitive to noise, you may want to wear ear protection when using this saw.

Overall, the Makita GN900SE is a great saw for the price. It's powerful, versatile, and easy to use. However, it's not the most portable saw on the market, and it can be noisy. If you're looking for a powerful and versatile saw that's still relatively lightweight and quiet, the Makita GN900SE is a great option.

Makita GN900SE Problems and Solutions

Sure. Here are some common issues and problems with the Makita GN900SE miter saw, along with solutions from experts:

• The saw blade does not spin. This could be due to a number of problems, such as a loose belt, a faulty switch, or a problem with the motor. To troubleshoot, first check the belt to make sure it is properly tensioned. If the belt is loose, tighten it according to the manufacturer's instructions. If the belt is not loose, check the switch to make sure it is functioning properly. If the switch is faulty, it will need to be replaced. If the motor is the problem, it will need to be serviced or replaced.
• The saw blade makes a loud noise. This could be due to a number of problems, such as a dull blade, a bent blade, or a problem with the bearings. To troubleshoot, first check the blade to make sure it is sharp. If the blade is dull, it will need to be sharpened. If the blade is not dull, check to see if it is bent. If the blade is bent, it will need to be replaced. If the bearings are the problem, they will need to be lubricated or replaced.
• The saw blade wanders. This could be due to a number of problems, such as a crooked fence, a loose miter gauge, or a problem with the blade alignment. To troubleshoot, first check the fence to make sure it is square to the saw blade. If the fence is not square, it will need to be adjusted. If the fence is square, check the miter gauge to make sure it is properly aligned. If the miter gauge is not aligned, it will need to be adjusted. If the blade alignment is the problem, it will need to be corrected.
• The saw blade binds. This could be due to a number of problems, such as a dirty blade, a dull blade, or a problem with the arbor nut. To troubleshoot, first check the blade to make sure it is clean. If the blade is dirty, it will need to be cleaned. If the blade is not dirty, check to see if it is dull. If the blade is dull, it will need to be sharpened. If the blade is not dull, check the arbor nut to make sure it is properly tightened. If the arbor nut is not tightened, it will need to be tightened.

If you are unable to troubleshoot the problem yourself, you should contact a qualified Makita technician for assistance.
