3. Setup
Before operating the miter saw, ensure it is properly assembled and secured. Always work on a stable, level surface.
3.1 Unpacking and Inspection
- Carefully remove all components from the packaging.
- Inspect for any shipping damage. Do not operate the saw if damage is present.
- Ensure all listed components are present: miter saw unit, 216mm universal saw blade, workpiece supports, clamp.
3.2 Mounting the Saw
- Secure the miter saw to a workbench using bolts through the designated mounting holes in the base. This prevents movement during operation.
3.3 Installing Workpiece Supports and Clamp
- Insert the extendable workpiece supports into their respective slots on either side of the saw table. Adjust their length as needed for your material.
- Attach the screw clamp to the saw table. Position it to firmly hold the workpiece against the fence during cuts.

4. Operating Instructions
Always wear appropriate personal protective equipment (safety glasses, hearing protection, dust mask) when operating the saw.
4.1 Power Connection and Safety
- Connect the saw to a 230V AC power supply.
- Ensure the power cord is clear of the cutting path and cannot be damaged.
- Familiarize yourself with the location of the ON/OFF switch and the emergency stop (if applicable).
4.2 Adjusting Cutting Speeds
The HM90MP offers two cutting speeds to match different materials. Select the appropriate speed before starting the cut.
- Speed 1 (Lower RPM): Recommended for harder materials like metals (steel, aluminum, copper) and some plastics.
- Speed 2 (Higher RPM): Recommended for softer materials like wood and certain plastics.

4.3 Setting Miter Angles (Horizontal Cuts)
- Loosen the turntable locking knob.
- Rotate the turntable to the desired angle (between -45° and +45°). Use the angle scale for precision.
- Lock the turntable securely in place.
4.4 Setting Bevel Angles (Vertical Cuts)
- Loosen the bevel locking lever at the rear of the saw head.
- Tilt the saw head to the desired angle (up to 45° to the left). Use the bevel scale for accuracy.
- Securely tighten the bevel locking lever.

4.5 Using the Laser Guide and LED Light
- Activate the laser guide and LED work light using their respective switches.
- Align the laser line with your marked cutting line on the workpiece.
- The LED light provides optimal illumination of the cutting area, especially in low-light conditions.

4.6 Performing a Cut
- Place the workpiece firmly against the fence and secure it with the clamp.
- Ensure the saw blade is clear of the workpiece before starting the motor.
- Press the ON switch to start the motor. Allow the blade to reach full speed before beginning the cut.
- Slowly lower the saw head into the workpiece. For wider materials, utilize the pull function by pulling the saw head towards you, lowering it, and then pushing it through the material.
- Maintain a steady, controlled feed rate. Do not force the saw.
- Once the cut is complete, release the ON switch and allow the blade to stop completely before raising the saw head.
- Remove the workpiece only after the blade has stopped.
4.7 Cutting Different Materials
The HM90MP is designed for a variety of materials. Always select the correct speed and ensure the workpiece is properly supported and clamped.
- Wood (Hardwood & Softwood): Use Speed 2. Ensure the wood is free of foreign objects.
- Wood with Nails: The multi-function blade can cut through wood containing nails, but proceed with caution and a slower feed rate.
- Aluminum & Copper: Use Speed 1. Apply a suitable cutting lubricant if necessary to prevent blade overheating and material buildup.
- Steel: Use Speed 1. A slower, consistent feed rate is crucial.
- Plastic: Use Speed 1 or 2 depending on the type of plastic. Test on a scrap piece first to avoid melting or chipping.

5. Maintenance
Regular maintenance ensures the longevity and safe operation of your miter saw. Always disconnect the saw from the power supply before performing any maintenance or cleaning.
5.1 Cleaning
- After each use, clean the saw to remove dust, chips, and debris. Use a brush or compressed air.
- Pay special attention to the motor vents, blade guard, and moving parts to prevent buildup.
- Wipe down external surfaces with a damp cloth. Do not use harsh chemicals.
5.2 Blade Replacement
- Only use 216mm blades designed for miter saws and suitable for the materials you intend to cut.
- Refer to the detailed instructions in the full product manual for specific blade replacement steps, including locking the spindle and removing/installing the blade.
- Ensure the new blade is installed with the teeth pointing in the correct direction of rotation.
5.3 General Care
- Periodically check all screws and fasteners for tightness.
- Lubricate moving parts as recommended by the manufacturer (refer to the comprehensive manual).
- Store the saw in a dry, secure location, out of reach of children.
