How to use

Place the sliding mitre saw on a stable, flat, and secure workbench or stand before starting operation. Ensure the workpiece is firmly clamped against the fence to prevent movement during the cut. Connect the tool to an appropriate AC power source.

Always wait for the blade to come to a complete stop before lifting it out of the cut or removing any debris.

What to consider before purchase

• Verify that the maximum cutting capacity of 70 x 270 mm meets your project requirements
• Ensure you have a stable workspace and compatible AC power supply
• Consider the weight and dimensions if you plan to transport the saw frequently

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and ear protection, when operating the saw. Regularly inspect the blade for dullness or damage and replace it as needed to maintain cutting accuracy. Keep the work area clean and ensure the dust extraction port is connected to a vacuum system to maintain visibility and a safe environment.
