Operation

The following operating procedures apply to both the TDRILS213 and the TDRILS226. Where drill size ranges differ between models, the relevant range is noted.

A. Setting Up the Drill Bit in the ER Collet Chuck

1. Determine the diameter of your drill bit and select the appropriate collet and chuck.
2. Insert the collet into the chuck at a 45° angle and tighten the nut slightly.
3. Insert the drill bit so that approximately 35 mm extends beyond the chuck. Do not fully tighten yet.

B. Aligning the Drill Bit

1. Reset the scale ring by turning it fully clockwise, then anti-clockwise to match the drill size.
2. Insert the chuck set into the web adjustment shelf and tighten clockwise.
3. Push the drill fully in and turn it clockwise.
4. Tighten the chuck set securely, then gently remove.

C. Grinding the Point Angle

1. Switch on the power and allow 10 seconds for the motor to stabilise.
2. Insert the chuck set into the point angle grinding shelf, aligning pins correctly.
3. Move the drill gently left and right until the grinding sound stops.
4. Rotate and repeat for the opposite side.

D. Grinding the Lip Relief Angle

1. Insert the chuck set into the lip relief angle grinding shelf.
2. Move left and right until grinding sound stops, then repeat on the other side.

Maintenance

1. Cleaning & Rust Prevention

• Remove debris after use.
• Apply a rust inhibitor to metal parts before storage.

2. Lubrication & Inspection

• Lubricate bearings and moving parts regularly with heat-resistant grease.
• Inspect the grinding wheel for cracks or heavy wear. Replace immediately if damaged.
• Ensure all fasteners are secure.

3. Storage & Safety

• Store in a dry place, covered when not in use.
• Regularly inspect power cables, switches, and fuses.

Replacing the Wheel

A. Open the Wheel Cover

1. Ensure the power cord is unplugged before proceeding.
2. Use a 4 mm hex wrench to loosen the screw and open the cover.

B. Removing and Replacing the Grinding Wheel

1. Use a brush to clean the machine, then wipe the surface with a dry cloth.
2. If the machine was recently used, wait at least 3 minutes for the grinding wheel to cool down.
3. Hold the wheel firmly with your left hand. Using your right hand, turn the screw counterclockwise with a 4mm hex wrench to loosen it.
4. Remove the diamond grinding wheel from the machine.
5. Insert the new grinding wheel.
6. Place the wheel onto the motor's principal axis, then tighten the screw and reinstall the wheel cover to complete the replacement.
