This manual provides essential instructions for the safe operation and maintenance of the HiKOKI D 10VST (L) drill. Always read the safety warnings before use. Ensure the power source matches the product nameplate and that the switch is in the OFF position before plugging in the tool.
Safety Warnings
General Power Tool Safety: Keep the work area clean and well-lit. Do not operate in explosive atmospheres. Keep children and bystanders away. Use personal protective equipment, including eye protection. Prevent unintentional starting by ensuring the switch is in the OFF position before connecting to power.
Drill Safety: Hold the tool by insulated gripping surfaces when performing operations where the cutting accessory may contact hidden wiring. Always start drilling at low speed and apply pressure only in a straight line with the bit. Do not wear gloves made of material liable to roll up (e.g., cotton, wool).
Specifications
The drill features a 450 W power input and a no-load speed of 0–3200 min–1. It has a 10 mm drill chuck capacity. Drilling capacity is 10 mm for steel and 25 mm for wood. The tool weighs 1.3 kg.
Mounting and Dismounting Bits
For Keyed Chuck: Open the chuck jaws, insert the bit, and use the chuck wrench in each of the three holes to tighten clockwise. To remove, use the wrench counter-clockwise.
For Keyless Chuck: Hold the ring and turn the sleeve counter-clockwise to open. Insert the bit, then hold the ring and turn the sleeve clockwise to tighten. If difficult to loosen, fix the spindle with an open-end wrench and turn the sleeve counter-clockwise.
How to Use
Switch Operation: Pull the trigger to rotate the tool; release to stop. Pulling the trigger and pushing the stopper keeps the tool in the ON position for continuous running. Pull the trigger again to release the stopper.
Drilling: Start slowly and gradually increase speed. Apply pressure in a straight line. If the drill stalls, release the trigger immediately and remove the bit from the work before restarting.
Maintenance and Inspection
Regularly inspect drill bits for abrasion and replace or resharpen them. Check all mounting screws for tightness. Keep the motor winding clean and free of oil or water. Carbon brush inspection and replacement, as well as supply cord replacement, must be performed ONLY by a HiKOKI Authorized Service Center.
