Detailed Description

The motor drives a cutting bit through the 1/4-inch collet. The base seat rests on the workpiece and helps maintain a consistent relationship between the bit and the surface. A fixing knob and adjustment mechanism allow the cutting depth to be set before work begins.

The main controls and components include the switch button, base plate, base seat, depth indicator, fixing knob, adjusting screw, collet, clamping nut, and cutting bit. Two spanners are used when installing or removing a bit. The supplied guide bush supports template work, while the parallel guide and guide bar help maintain a fixed distance from an edge or create circular cuts. A bearing guide can follow the edge of furniture or another workpiece for controlled trimming.

For template routing, the bit passes through the guide bush while the guide follows the template outline. For edge work, the parallel guide or bearing guide provides a reference surface. Always choose an accessory that is supported by the tool and suitable for the intended operation.

Safety

Work Area

• Keep the work area clean, organized, and well lit.
• Keep children and bystanders away while the tool is operating.
• Do not use the trimmer where flammable liquids, gases, vapors, or dust could be ignited by sparks.
• Secure the workpiece so it cannot shift during routing.
• Remove screws, nails, nuts, and other metal objects from the workpiece before cutting.

Electrical Safety

• Use a matching electrical outlet and never modify the plug.
• Keep the power cord away from heat, oil, sharp edges, and moving parts.
• Do not carry, pull, or unplug the tool by its cord.
• Do not expose the trimmer to rain or wet conditions.
• When outdoor use requires an extension cord, use one rated for outdoor applications.
• If use in a damp location cannot be avoided, connect the tool to an RCD-protected supply.

Personal Protection

• Wear safety glasses, hearing protection, and a dust mask.
• Wear suitable non-slip footwear and keep stable footing.
• Do not operate the tool while tired or under the influence of drugs, alcohol, or medication.
• Keep loose clothing, jewelry, gloves, and long hair away from rotating parts.
• Keep both hands away from the cutting bit, even when wearing gloves.
• Hold the tool by its insulated handle surfaces, particularly when hidden wiring could be present.

Bit and Operating Safety

• Disconnect the plug before adjustments, accessory changes, inspections, or storage.
• Inspect the cutting bit before installation. Do not use a bit that is cracked, broken, or otherwise damaged.
• Install the bit securely with the correct size and compatible accessory.
• Do not touch the cutting bit during operation or immediately afterward; it can become very hot.
• Before switching on, make sure the bit is not touching the workpiece or another object.
• Run the tool briefly before cutting and check for unusual vibration, wobble, or poor bit installation.
• Maintain the correct feeding direction and keep the base plate firmly against the workpiece.
• Do not place the tool down until the switch is off and the bit has stopped completely.
• Remove a cutting bit only after the tool is switched off, unplugged, and fully stopped.
• Use only accessories approved for this type of tool.

Setup and Operation

Adjust the Cutting Depth

1. Switch the tool off and disconnect the plug from the electrical supply.
2. Loosen the fixing knob.
3. Move the base seat assembly until the desired cutting depth is reached.
4. Use the depth indicator and adjusting mechanism to help set the position.
5. Tighten the fixing knob securely before connecting power.

The maximum cutting depth is 3 mm. If a deeper result is needed, make several controlled passes instead of attempting the full depth in one cut.

Install or Remove a Cutting Bit

1. Unplug the tool and place it securely so the collet area is accessible.
2. Insert the compatible cutting bit into the collet.
3. Use the two spanners to tighten the clamping nut and secure the bit.
4. Check that the bit is seated correctly and cannot move.
5. To remove the bit, use the spanners and reverse the installation procedure only after the tool is unplugged and stopped.

Switch the Tool On and Off

1. Place the base on the workpiece without allowing the bit to touch the material.
2. Turn the switch button to the “1” position to start the motor.
3. Allow the tool to reach full speed.
4. Move the switch to the “O” position to turn the tool off.

Make a Basic Cut

1. Mark the intended cutting line and secure the workpiece.
2. Test the setup on a scrap piece of similar material.
3. Start the trimmer with the bit clear of the workpiece.
4. When full speed is reached, move the tool forward in the correct feeding direction.
5. Keep the base plate flat and firmly supported against the workpiece.
6. Advance at an even speed without forcing the motor.
7. At the end of the cut, switch off the tool and wait for the bit to stop before lifting it away.

Feeding too quickly can produce a poor finish and overload the motor or bit. Feeding too slowly can overheat the bit and mark the workpiece. A trial cut helps determine the appropriate speed for the material and bit.

Use the Parallel Guide

1. Attach the guide bar to the parallel guide with the bolt and wing nut.
2. Attach the parallel guide to the base plate with the fixing screw.
3. Loosen the wing nut and set the distance between the cutting bit and the guide.
4. Tighten the wing nut once the desired distance is established.
5. Keep the guide against the workpiece edge while moving the trimmer steadily.

The parallel guide is useful for edge trimming and grooves. When the required distance is too far for the guide to reach, fasten a straight plate securely to the workpiece and use that plate as a guide surface.

Install the parallel guide on the right-hand side of the feeding direction as specified for this tool.

Use the Guide Bush and Template

1. Disconnect the tool from power.
2. Remove the base plate by loosening its screws.
3. Position the guide bush on the base plate.
4. Reinstall the base plate and tighten the screws securely.
5. Fasten the template or logo guide to the workpiece.
6. Place the tool on the guide and move it forward so the guide bush follows the template edge.

The guide bush allows the cutting path to follow a template while keeping the bit aligned with the guide outline.

Cut Circles

The parallel guide can be configured as a circle-cutting guide. The usable cutting radius is 70 mm to 221 mm, except for the range from 172 mm through 186 mm.

• For radii from 70 mm to 121 mm, assemble the parallel guide in the smaller-radius arrangement.
• For radii from 121 mm to 221 mm, use the larger-radius arrangement.

1. Assemble the guide bar, wing nut, parallel guide, bolt, and center hole according to the intended radius.
2. Place the center hole over the center mark on the workpiece.
3. Insert a nail smaller than 6 mm through the center hole to hold the guide in place.
4. Move the trimmer clockwise around the center point while maintaining steady contact with the guide.

Use the Bearing Guide

1. Attach the bearing guide to the base plate using fixing nut A.
2. Loosen fixing nut B to adjust the distance between the cutting bit and the bearing guide seat.
3. Set the required distance and tighten fixing nut B.
4. During cutting, keep the bearing guide firmly against the workpiece edge.
5. Move the tool smoothly to maintain a consistent trim.

The bearing guide is useful for following furniture edges and similar profiles while keeping the cutting path controlled.

Cleaning and Maintenance

Routine Care

• Disconnect the plug before inspection or cleaning.
• Clean the tool with a brush. Do not use water or other liquids.
• Keep the air vents clear so the motor can cool properly.
• Check regularly that the tool components and fasteners remain secure.
• Inspect the housing for cracks or other damage.
• Inspect the power cord for cuts, abrasion, or other damage.
• Do not clean the base plate with solvent, oil, gasoline, or impregnating agents because these substances may damage it.

Replace the Carbon Brushes

Carbon brushes should be replaced if the motor does not run or produces excessive sparking. Burned, broken, or excessively worn brushes must be replaced, and both brushes should be changed at the same time using matching original-type replacements.

1. Disconnect the tool from the power supply.
2. Loosen the black brush-holder caps on the sides of the housing with a screwdriver.
3. Remove the worn brushes and clear dust from the holders with compressed air.
4. Install the new brushes in the reverse order.
5. Confirm that each brush moves freely in its holder.
6. Run the tool for several minutes so the new brushes can seat properly.

If brush replacement does not correct the problem, stop using the trimmer and have it inspected by a qualified repair person. Repairs should use identical replacement parts to preserve the tool’s safety.

Troubleshooting

• The tool does not start: Confirm that the plug is connected, the switch is in the “1” position, and the cord is undamaged. Worn carbon brushes may also prevent operation.
• The motor produces excessive sparks: Stop using the tool and inspect the carbon brushes. Replace both brushes if they are worn, burned, or broken.
• The cut is rough or inaccurate: Check that the bit is sharp, correctly installed, and free from damage. Confirm that the base remains flat and that the guide is secured.
• The bit or motor becomes too hot: Reduce the feeding speed, avoid forcing the tool, clear the ventilation openings, and use multiple shallow passes when greater depth is required.
• The tool vibrates or swings: Switch it off immediately, unplug it, and check the bit, collet, clamping nut, and base assembly. Do not continue until the cause has been corrected.
• The tool overloads: Reduce the cutting depth and feed rate. A maximum single-pass depth of 3 mm must not be exceeded.

Environmental and Symbol Information

The tool is double insulated for additional protection. Read the instruction manual before use and wear eye protection, hearing protection, and a dust mask during suitable operations.

Do not dispose of the trimmer with ordinary household waste. Electrical products should be directed to an appropriate recycling facility in accordance with local requirements.
