5.2. Router Bit Installation
Always ensure the router is turned off and the battery is removed before installing or changing bits.
- Loosen Collet Nut: Use the provided wrenches to loosen the collet nut on the router base.
- Insert Bit: Insert the shank of the desired router bit into the collet. Ensure the bit is inserted far enough to provide a secure grip, but do not bottom it out.
- Tighten Collet Nut: While holding the spindle lock button (if present) or using the second wrench, firmly tighten the collet nut with the wrench. Do not overtighten.

5.3. Depth Adjustment
Adjusting the routing depth is crucial for precise cuts.
- Unlock Base: Loosen the locking lever or knob on the router base that secures the motor housing.
- Set Depth: Lower or raise the motor housing until the router bit reaches the desired depth relative to the base plate. Use the depth scale and fine adjustment knob for accuracy.
- Lock Base: Securely tighten the locking lever or knob to fix the depth setting.

6. Operating Instructions
6.1. Powering On/Off
To turn the router ON, press the power button. To turn it OFF, press the power button again. Always ensure a firm grip on the tool before starting.
6.2. Speed Control
The JEXUGK router features a 6-speed variable control, allowing you to match the speed to the material and bit type for optimal results. The speed can be adjusted from 0 to 35,000 RPM.
- Lower Speeds (1-2): Suitable for larger diameter bits, softer woods, or when more control is needed.
- Medium Speeds (3-4): Ideal for general routing tasks and medium-density woods.
- Higher Speeds (5-6): Best for smaller diameter bits, harder woods, and fine detail work.

6.3. General Operation
Always perform a test cut on scrap material before routing your final workpiece.
- Workpiece Securement: Ensure your workpiece is securely clamped to prevent movement during routing.
- Starting the Cut: Hold the router firmly with both hands. Start the router before the bit contacts the workpiece.
- Direction of Feed: Always feed the router against the rotation of the bit. This provides better control and prevents the router from running away.
- Dust Collection: Attach the dust collection hood to minimize sawdust and maintain a clear view of your work.
- Applications: This router is suitable for edge trimming, surface polishing, slot cutting, furniture rounding, mortise and tenon construction, and various DIY woodworking projects.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your router. Always disconnect the battery before performing any maintenance.
- Cleaning: After each use, clean the router body, base, and collet area with a soft, dry cloth. Use compressed air to clear dust from vents. Do not use harsh chemicals or abrasive cleaners.
- Router Bits: Keep router bits sharp and clean. Dull bits can cause kickback and poor cut quality. Clean resin and pitch buildup from bits using a specialized bit cleaner.
- Battery Care: Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. Do not store fully discharged batteries for extended periods.
- Inspection: Periodically inspect the power cord (if using a corded charger), switches, and housing for any damage. Replace damaged parts immediately.
