- Attaching Auxiliary Handle:
The 2-position auxiliary handle can be screwed into either side of the grinder's gear housing. Choose the position that provides the best control and comfort for your application.
- Installing Wheel Guard:
Loosen the clamp screw on the wheel guard. Position the guard over the spindle collar, ensuring it covers the wheel adequately for your task. Tighten the clamp screw securely. Adjust the guard's position as needed for optimal protection.
- Mounting Grinding/Cutting Wheels:
Press and hold the spindle lock button. Place the inner flange onto the spindle. Position the desired grinding, cutting, or flap wheel onto the spindle, ensuring it sits flat against the inner flange. Place the outer flange over the wheel and tighten it with the spanner wrench. Release the spindle lock.
Operating Instructions
DCK Random Orbital Sander (KSA125)
- Power Connection:
Plug the sander into a standard 120V AC power outlet.
- Speed Control:
The sander features a 6-speed control dial. Rotate the dial to select the desired orbit per minute (OPM) from 4000 to 12000 OPM. Lower speeds are suitable for delicate work or polishing, while higher speeds are for aggressive material removal.

- Starting and Stopping:
To start, press the ON/OFF switch. To stop, release or press the switch again. Always hold the sander firmly with both hands during operation.
- Sanding Technique:
Place the sander flat on the workpiece before turning it on. Apply light, even pressure and move the sander in overlapping passes. Avoid tilting the sander or applying excessive pressure, as this can lead to uneven sanding and damage to the workpiece or tool.
DCK Angle Grinder (KSM09-115S)
- Power Connection:
Plug the grinder into a standard 120V AC power outlet.
- Starting and Stopping:
To start the grinder, slide the lockout switch forward and press the trigger. Some models may have a lock-on button for continuous operation. To stop, release the trigger or press the lock-on button again. Always ensure the tool is off before plugging or unplugging.
- Grinding/Cutting Technique:
Hold the grinder firmly with both hands. Allow the tool to reach full speed before contacting the workpiece. For grinding, use a slight angle and move the wheel smoothly across the surface. For cutting, use the edge of the wheel and make straight, controlled passes. Always direct sparks away from yourself and others.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your DCK power tools. Always disconnect the tool from the power source before performing any maintenance.
- Cleaning: Regularly clean the tool's exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Keep ventilation openings clear of dust and debris to prevent overheating.
- Dust Bag (Sander): Empty the dust bag frequently to maintain optimal dust collection efficiency. The bag is removable for easy cleaning.
- Carbon Brushes (Grinder): Inspect carbon brushes periodically. Replace them when they are worn down to approximately 1/4 inch (6mm) or if the motor sparks excessively. Refer to the grinder's specific user manual for brush replacement procedures.
- Wheel Inspection (Grinder): Before each use, inspect grinding and cutting wheels for cracks, chips, or damage. Replace any damaged wheels immediately.
- Storage: Store tools in a dry, secure location out of reach of children.
