Setup

1. Attaching the Base

The trimmer base is designed for quick attachment and removal. Ensure the base is clean and free of debris before attaching it to the motor unit.

Figure 2: The clamp lever on the trimmer base allows for quick and secure fixation of the base to the motor unit. Push the lever down to lock and pull up to release.

2. Installing/Changing Routing Bits

Always ensure the trimmer is unplugged from the power source before changing bits.

1. Press and hold the spindle lock button to prevent the spindle from rotating.
2. Use the provided wrench to loosen the collet nut.
3. Insert the desired routing bit into the collet, ensuring it is fully seated.
4. Tighten the collet nut firmly with the wrench while holding the spindle lock. Do not overtighten.

Figure 3: The spindle lock feature allows for convenient bit changes using a single wrench, simplifying the process of attaching and detaching routing bits.

3. Adjusting Cutting Depth

The trimmer features a micro-adjustment ring for precise control over cutting depth.

1. Loosen the base clamp lever.
2. Rotate the screw-type adjustment ring to set the desired cutting depth. Turning the ring clockwise typically increases depth, while counter-clockwise decreases it.
3. Once the desired depth is set, firmly secure the base clamp lever.
4. Perform a test cut on a scrap piece of material to verify the depth setting before working on your main project.

Operating Instructions

1. Powering On/Off

The trimmer is equipped with a visible slide switch for easy power control.

• To turn ON: Slide the switch upwards.
• To turn OFF: Slide the switch downwards.
• For safety, when placing the tool down or during breaks, ensure the switch is in the "OFF" position.

Figure 5: The slide switch is clearly visible and easy to operate. Pushing it up turns the power ON, and pushing it down turns it OFF. The image shows the trimmer in operation.

2. General Operation Tips

• Always secure your workpiece firmly to prevent movement during operation.
• Maintain a firm grip on the trimmer with both hands.
• Start the trimmer before making contact with the workpiece.
• Move the trimmer smoothly and consistently across the material. Avoid forcing the tool, as this can lead to poor cuts and potential kickback.
• For deeper cuts, it is often better to make multiple shallow passes rather than one deep pass.
• Always route against the direction of bit rotation to maintain control.

Maintenance

Regular maintenance ensures the longevity and safe operation of your trimmer. Always unplug the tool before performing any maintenance.

1. Cleaning

• After each use, clean the trimmer body, base, and collet area with a dry cloth or soft brush to remove dust and debris.
• Do not use solvents or harsh chemicals, as they may damage plastic parts.
• Ensure ventilation openings are clear to prevent overheating.

2. Bit Care

• Keep routing bits sharp and clean. Dull bits can cause overheating, poor cuts, and increased strain on the motor.
• Store bits in a protective case to prevent damage.

3. Dust Collection (Optional)

For cleaner operation and to prolong tool life, consider using a dust collection system.

Figure 6: The trimmer can be connected to a dust collection system using an optional nozzle set and hose (sold separately) for a cleaner work environment.

Figure 7: Optional accessories include a dust collection adapter for connecting to a dust hose and a dovetail guide (10mm outer diameter / 8mm inner diameter) for precise template-based routing.
