2. Safety Instructions

Always adhere to general power tool safety guidelines and the following specific instructions when operating the Metabo CS 22-355 chop saw. Failure to do so may result in serious injury or damage to the tool.

• Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, and appropriate work gloves. A face shield is also recommended to protect against sparks and debris.
• Work Area: Ensure the work area is clean, well-lit, and free from flammable materials. Sparks generated during cutting can ignite combustible substances.
• Secure Workpiece: Always firmly clamp the material to be cut using the quick-positioning vise. Unsecured workpieces can move, causing kickback or inaccurate cuts.
• Blade Inspection: Before each use, inspect the abrasive cutting disc for cracks, chips, or damage. Never use a damaged disc.
• Proper Blade Type: Use only 14-inch x 1-inch arbor chop saw wheels rated for chop saw applications and suitable for the material being cut.
• Avoid Overreaching: Maintain proper footing and balance at all times. Do not overreach while operating the saw.
• Integrated Safety Switch: The tool features an integrated safety switch with a lock-out feature to prevent accidental start-up. Familiarize yourself with its operation.
• Ventilation: Ensure adequate ventilation to disperse dust and fumes generated during cutting.
• Power Cord: Keep the power cord away from the cutting area and moving parts. Inspect the cord for damage before use.

3. Unpacking and Contents

Carefully unpack your Metabo CS 22-355 chop saw and verify that all components are present and undamaged. If any items are missing or damaged, contact your supplier immediately.

Package Contents:

• Metabo CS 22-355 Chop Saw Unit
• Hexagonal Wrench
• Inner Support Flange
• Flange Nut
• Instruction Manual (this document)

4. Setup

Follow these steps to set up your chop saw for operation.

4.1. Workstation Preparation

• Place the chop saw on a stable, level, and secure workbench or surface capable of supporting the tool's weight and the forces generated during cutting.
• Ensure adequate clearance around the saw for the workpiece and for safe operation.

4.2. Abrasive Disc Installation

The Metabo CS 22-355 features an easy and quick disc change with a spindle lock mechanism.

1. Ensure the saw is unplugged from the power source.
2. Press and hold the spindle lock button to prevent the spindle from rotating.
3. Using the hexagonal wrench, loosen and remove the flange nut and outer support flange.
4. Place the new 14-inch abrasive cutting disc onto the spindle, ensuring it sits flush against the inner support flange. The disc's rotation arrow must match the arrow on the saw's guard.
5. Reinstall the outer support flange and flange nut. Tighten the flange nut securely with the hexagonal wrench while holding the spindle lock button. Do not overtighten.
6. Release the spindle lock button.

4.3. Adjusting the Quick-Clamping Vise

The quick-clamping vise allows for fast securing of various sized materials.

• To adjust the vise opening, rotate the handle to move the movable jaw.
• Position the workpiece against the fixed jaw and then tighten the movable jaw firmly against the workpiece.

4.4. Miter Angle Adjustment

Miter cuts from -15° to 45° are possible with the variable miter conversion feature.

• Loosen the locking mechanism for the miter fence.
• Adjust the miter fence to the desired angle (-15° to 45°). Refer to the angle scale for precision.
• Securely tighten the locking mechanism to fix the miter fence in place.

4.5. Adjustable Cutting Depth Limiter

The cutting depth limiter can be adjusted for optimal use of the cutting disc and to prevent cutting into the base unnecessarily.

• Adjust the screw or lever located on the saw to set the desired maximum cutting depth.
• Ensure the adjustment allows the disc to fully cut through the workpiece without excessive downward travel.

5. Operating Instructions

Before operating, ensure all safety precautions are understood and followed.

5.1. Powering On/Off

• Plug the saw into a suitable power outlet.
• To start the saw, press the safety switch (if applicable) and then the main trigger switch.
• To stop the saw, release the trigger switch. The integrated safety switch with lock-out feature protects against accidental start-up.

5.2. Cutting Procedure

1. Secure Workpiece: Place the material to be cut firmly against the miter fence and secure it tightly with the quick-clamping vise. Ensure the cutting line is clear of the vise jaws.
2. Positioning: Hold the saw's handle firmly. The large handle lateral to the cutting axis is designed for optimal force transmission during cutting.
3. Start Saw: Start the saw and allow the abrasive disc to reach full speed before beginning the cut.
4. Execute Cut: Slowly and steadily lower the cutting disc into the workpiece. Do not force the cut; allow the disc to do the work. Excessive pressure can damage the disc or motor.
5. Complete Cut: Continue lowering until the cut is complete.
6. Retract Saw: Once the cut is finished, release the trigger switch and allow the disc to stop rotating before raising the saw head.
7. Remove Workpiece: Unclamp and remove the cut workpiece. Be aware that the cut material and the disc may be hot.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your Metabo CS 22-355 chop saw.

• Cleaning: After each use, unplug the saw and clean off dust and debris from the motor vents, blade guard, and base. Use compressed air if available.
• Blade Inspection: Regularly inspect the abrasive cutting disc for wear, cracks, or damage. Replace worn or damaged discs immediately.
• Vise Mechanism: Keep the quick-clamping vise mechanism clean and lubricated to ensure smooth operation.
• Power Cord: Periodically check the power cord for cuts, fraying, or other damage. Replace a damaged cord immediately.
• Carbon Brushes: If the saw experiences reduced power or excessive sparking from the motor, the carbon brushes may need inspection or replacement. This should ideally be performed by a qualified service technician.

7. Troubleshooting

This section addresses common issues you might encounter with your Metabo CS 22-355 chop saw.

7.1. Saw Does Not Start

• Check Power: Ensure the saw is properly plugged into a functional power outlet.
• Circuit Breaker: Check if the circuit breaker has tripped.
• Safety Switch: Confirm that the safety switch and trigger switch are being engaged correctly.
• Power Cord: Inspect the power cord for any visible damage.

7.2. Poor Cutting Performance / Excessive Sparks

• Worn Disc: The abrasive disc may be worn out or dull. Replace it with a new, appropriate disc.
• Incorrect Disc: Ensure you are using the correct type of abrasive disc for the material being cut.
• Forcing Cut: Avoid applying excessive pressure. Let the saw's speed and the disc's abrasiveness do the work.
• Workpiece Secureness: Ensure the workpiece is clamped firmly. Movement during cutting can lead to poor performance.

7.3. Excessive Vibration

• Damaged Disc: Inspect the abrasive disc for damage, cracks, or imbalance. Replace if necessary.
• Loose Components: Check if the blade flanges or other components are securely tightened.
• Unstable Surface: Ensure the saw is placed on a stable and level surface.
