Frequently Asked Questions - FWS-125KN Ferm

How do I change the cutting discs on the Ferm FWS-125KN?

First, unplug the tool. Use the cam wrench and hex key provided to loosen the flange nut. Remove the old discs and install new ones, ensuring they are the correct size (125 mm diameter, 22.2 mm bore). Tighten the nut securely. Refer to the manual for detailed diagrams.

How do I adjust the cutting depth?

Locate the depth adjustment knob on the machine. Turn it to set the desired depth between 8 and 30 mm. Use the scale on the tool for reference. Always check the setting before starting.

Can I adjust the channel width?

Yes, the channel width can be adjusted from 8 to 26 mm. Use the width adjustment mechanism (a lever or knob) on the side of the tool. Refer to the manual for precise steps.

How do I connect the dust extraction system?

Attach the provided dust extraction adapter to the connection port on the tool. Connect it to a suitable vacuum cleaner or dust extractor. This helps minimize dust during operation.

What safety precautions should I take when using the wall chaser?

Always wear safety glasses and a dust mask. Ensure the work area is well-lit and free of flammable materials. Do not use in wet conditions. Check for concealed cables or pipes before cutting. Keep children and bystanders away. Use outdoor extension cords if working outdoors.

The motor cuts out during use. What could be the cause?

The overheat protection may have activated. Wait several minutes for the tool to cool down. If it still won't start, check the overload protection or the switch. If the motor is defective, take it to a Ferm dealer for repair.

Why does the machine vibrate heavily when cutting?

Heavy vibration is often caused by bent or overheated cutting discs. Replace the discs with new ones. Also, ensure the discs are properly mounted and the spindle is balanced.

How often should I clean the tool?

Clean the tool after each use. Use a dry cloth to remove dust from the ventilation slots. Do not use flammable liquids. Regular cleaning prevents motor overheating and ensures safe operation.

How should I store the wall chaser when not in use?

Store the tool in a dry, high, or lockable place, out of reach of children. Keep it in its original packaging or a suitable case. Disconnect the plug and store the cord loosely.
