The HiKOKI NR 1890DCA is a cordless strip nailer designed for wood framing and construction. Before use, ensure the battery is fully charged and the correct nailing mode is selected. Always wear eye protection and keep hands away from the firing head. The tool features a brushless motor, LED light, and a dry-fire lockout mechanism.
Safety Warnings
- Eye Protection: Always wear safety goggles compliant with AS/NZS 1337.
- Trigger Safety: Keep fingers away from the trigger when not actively nailing.
- Kickback: Be aware of tool recoil; do not press against the workpiece with excessive force.
- Jam Clearing: Always remove the battery and all nails before attempting to clear a jam.
- Prohibited Use: Do not use the nailer on scaffolding or ladders. Do not use it as a hammer.
Charging the Battery
Use the UC18YSL3 charger. Insert the battery firmly. The charge indicator lamp will blink blue during charging and turn green when complete. If the lamp blinks red, check for proper insertion or overheating. Allow the charger to rest for 15 minutes between consecutive charging cycles.
Operation
The nailer features two operation modes (except for New Zealand models, which are Full Sequential only):
- Full Sequential Actuation: Press the push lever against the wood, then pull the trigger.
- Contact Actuation: Pull the trigger first, then press the push lever against the wood to drive a nail.
Trigger Lock: Always engage the trigger lock when the tool is not in use.
Depth Adjustment: If nails are driven too deep or shallow, use the adjuster on the firing head to change the depth in half-turn increments.
Maintenance and Inspection
- Cleaning: Regularly blow out the magazine and feeder mechanism to prevent jams.
- Jam Clearing: If a jam occurs, remove the battery and nails, then use the provided Torx bar wrench to remove the magazine bolts and clear the firing head.
- Storage: Store in a cool, dry place out of reach of children.
Troubleshooting
- Nailer won't turn on: Check battery charge or ensure the power switch was held for more than 1 second.
- Nailer won't fire: Ensure the push lever is pressed firmly against the workpiece and the trigger is pulled within 2 seconds of the push lever activation.
- Weak drive: Adjust the nailing depth or check battery charge.
