Quick guide from the manual
The HiKOKI NH 18DSL is a cordless auto hammer designed for driving nails into wood and similar materials. This document provides essential safety, operation, and maintenance instructions. Always wear eye and ear protection during use. Never point the tool at yourself or others, and ensure the tool is firmly pressed against the workpiece before actuation.
Device Description
The tool features a firing head (outlet), a rod, an LED light, a trigger, a hook, and a battery compartment. It uses a magnetic system to hold nails in place during operation.
Operation
Before use, ensure the rod slides smoothly. To operate, insert the battery, press the nail outlet firmly against the material, and pull the trigger. The tool can be used by holding a nail with the magnet or with fingers (placing the nail tip on the target first). Always remove the battery and remaining nails when not in use, during maintenance, or when clearing a jam.
Safety
- Always assume the tool contains nails.
- Do not use for fastening electrical cables.
- Do not use on scaffolding or ladders.
- Keep hands and feet away from the firing head.
- Be aware of kickback; do not approach the top of the tool with your head.
- Do not use near flammable substances like paint, gasoline, or adhesives.
- The operating temperature range is 0°C to 40°C.
- Keep magnets away from the tool as it contains an internal magnet.
Maintenance and Troubleshooting
- Clearing a jam: Remove the battery, then use pliers to remove the jammed nail.
- Rod inspection: Periodically clean and lubricate the sliding part of the rod. If iron powder accumulates on the magnet, clean it with a cloth or adhesive tape to maintain magnetic holding power.
- Motor maintenance: Ensure the motor winding remains clean and dry.
- Cleaning: Use a soft dry cloth or a cloth moistened with soapy water. Do not use gasoline or chloric solvents.

Common problems
Motor stops during use
This may be due to the protection function. If the battery is low, charge it. If overloaded, release the trigger and remove the cause of the overload. If overheated, let the battery cool down.
Nail jam
Remove the battery, then use pliers to remove the jammed nail. If jams occur frequently, contact an authorized service center.
Reduced magnetic holding power
Clean the magnetized area inside the rod and the magnet outside the rod with a cloth or adhesive tape to remove iron powder.
Before use
- Ensure the rod slides smoothly.
- Check that all mounting screws are tightened.
