Quick guide from the manual
This document provides essential operating instructions for the Hikoki DH 18DPA cordless rotary hammer. Key operations include battery installation, selecting between rotation and hammering modes, and utilizing the auto-stop function for consistent drilling. Always ensure the tool is switched off and the battery is removed before performing any maintenance or changing accessories.
Device Overview
The tool features a switch trigger, change lever for mode selection, side handle for stability, and a depth gauge. It is powered by a rechargeable lithium-ion battery. The display panel provides status indicators for the auto-stop function and protection alerts.
Operation
To operate, insert a charged battery. Use the change lever to select between Rotation + Hammering (for concrete/tile) or Rotation only (for wood/metal with optional chuck). The tool features a variable speed trigger; pull it gently for lower speeds and further for higher speeds. The Auto stop function can be used for continuous drilling by storing the drilling time in memory.
Safety and Protection
The tool includes a Reactive Force Control (RFC) feature to reduce jerking if the bit suddenly binds. If the tool stops due to overload or high temperature, the display lamp will flash. Allow the tool to cool or remove the cause of the overload before resuming. Always wear eye and ear protection.
Maintenance
Keep the tool and battery terminals free of dust and swarf, especially after drilling concrete. Use a dry cloth for cleaning. Do not use solvents that may melt plastic parts. Store the tool in a cool, dry place out of reach of children.
