The Yato 18V cordless drywall screwdriver is powered by 18 V direct current (d.c.) and comes with a 4000 mAh Li-Ion battery. The key performance metric of the device is its rotational speed of 0–4000 min⁻¹, which is electronically adjustable via the switch. The high rotational speed is optimized for the rapid fastening of drywall and wood-based panels. The total mechanical weight of the tool is 1.49 kg, designed to reduce strain during prolonged installation work, such as in the construction of ceilings and partition walls.

The device comes standard with a 1/4″ (6.3 mm) hexagonal chuck, allowing the use of standard screwdriver bits. The included collated screw attachment is calibrated to support collated screws with a diameter of 3.5–4.2 mm and a length of 25–55 mm. This attachment automates screw feeding and ensures continuous installation work without manual screw placement. The rotation direction switch allows for quick screw removal and changes in installation direction.

The power supply is provided by the system's 4.0 Ah lithium-ion battery, which enables long autonomous operation without mains power. The battery has an integrated charge level indicator, allowing real-time power consumption monitoring. The included charger restores the battery to full electrical charge in exactly 2 hours.

The structural safety of the tool's casing meets the requirements of the IPX0 rating, meaning the device is not protected against moisture ingress. The motor's rotational speed and torque are continuously variable, ensuring a consistent screw embedding depth regardless of material thickness. The ergonomic design supports one-handed operation in challenging working angles, such as overhead installations.

Intended Use and Suitability:

The collated screw gun is designed for serial installations in the construction industry that demand efficiency. The device's automatic feed and high rotational speed make it a primary choice for large-scale installation projects.

• Partition Walls and Ceilings: The collated screw attachment and 0-4000 min⁻¹ rotational speed enable serial fastening of drywall panels to metal and wood studs. The device automatically feeds 25-55 mm screws, accelerating the sheeting process over large areas and eliminating manual handling of individual screws.
• Installation of Wood-Based Panels: The 1/4″ hexagonal chuck and adjustable speed support the fastening of OSB boards, plywood, and other construction panels. Electronic speed control prevents overtightening of screw heads and damage to the material.
• Mobile Installation Work: The 18V battery system and the device's own weight of 1.49 kg allow for prolonged installation work in locations without a fixed power grid. The battery's capacity and 2-hour charging time minimize downtime on unpowered construction sites.

Yato YT-82075 User Manual:

Mechanical procedures for setting up and operating the device in industrial settings.

• 1. Power Source Connection: Using the charger, ensure the 18V battery has reached full charge (2-hour charging cycle). Slide the battery into the rail at the bottom of the handle until the mechanical lock clicks into place.
• 2. Tool Preparation: Choose whether to use the device with the collated screw attachment or the direct 1/4″ chuck. Install the collated screw attachment over the chuck and feed a 25-55 mm collated screw into the feeding channel according to the mechanical guides.
• 3. Adjusting Screwing Depth: Adjust the depth stop of the collated screw attachment according to the screw length (25-55 mm) and the thickness of the drywall. This ensures the screw head is flush with the material without breaking the board's surface paper.
• 4. Screwing Process: Position the device perpendicularly to the surface. Press the trigger and simultaneously push the machine steadily against the surface to be fastened. The switch controls the speed in the range of 0-4000 min⁻¹. The feeding mechanism automatically advances a new screw after each installation.
• 5. Maintenance: Remove the battery after the work phase is completed. Clean the feeding mechanism of the collated screw attachment and the 1/4″ chuck from drywall dust with compressed air to prevent jamming.

Warnings:

Critical technical warnings to ensure electrical and occupational safety.

• Moisture and Electrical Safety: The IPX0 rating does not provide protection against water ingress. Water entering the electric motor or battery connections poses an immediate risk of short-circuit.
• Mechanical Hazards: The collated screw feeding mechanism contains moving parts. Fingers or clothing entering the feeding channel can cause pinching or cutting hazards.
• Dust Exposure: Screwing drywall produces fine gypsum dust, which can wear down the motor and irritate respiratory tracts. Use of a P2-class respirator is mandatory.
• Hidden Structures: Ensure the backgrounds of surfaces to be screwed before installation to prevent accidental piercing of live wires, gas pipes, or water pipes.

Frequently Asked Questions, FAQ:

• Can the Yato YT-82075 model use individual drywall screws instead of collated screws? Yes, the collated screw attachment is detachable, allowing the device to function as a traditional drywall screwdriver with a standard 1/4″ (6.3 mm) hexagonal chuck.
• What lengths of collated screws can the feeder handle without jamming? The feeding mechanism is mechanically calibrated to support industry-standard collated screws of 25–55 mm in length and 3.5–4.2 mm in thickness.
• What is the exact time it takes for the battery to charge from empty to full? The included fast charger recharges the 18V 4000 mAh (4.0 Ah) lithium-ion battery from empty to full electrical charge in exactly 2 hours.
• Is the 18V battery included with the device compatible with other Yato tools? Yes, the 18V 4.0Ah Li-Ion battery belongs to the Yato 18V battery ecosystem and is mechanically and electrically compatible with other devices in the same system.

Recycling Instructions:

Material-specific instructions for the proper industrial recycling of components.
