WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

CORDLESS HAMMER DRIVER DRILL SAFETY WARNINGS GEB056-4

1.Wear ear protectors with impact drilling. Exposure to noise can cause hearing loss.

2.Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.

3.Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

4.Hold power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring. Fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

5.Always be sure you have a firm footing.

Be sure no one is below when using the tool in high locations.

6.Hold the tool firmly.

7.Keep hands away from rotating parts.

8.Do not leave the tool running. Operate the tool only when hand-held.

9.Do not touch the bit or the workpiece immediately after operation; they may be extremely hot and could burn your skin.

Makita BHP444, BHP454 Specifications, Cordless Hammer Driver Drill Safety Warnings GEB056-4, English Original instructions

BHP454, BHP444 specifications

The Makita BHP444 and BHP454 are powerful and versatile cordless hammer drills, designed to meet the needs of both professionals and DIY enthusiasts. These tools are engineered with advanced technologies to enhance performance, durability, and user comfort.

One of the standout features of the BHP444 is its compact design, which makes it easy to maneuver in tight spaces. With a lightweight frame, this model offers a comfortable grip, allowing users to work for extended periods without fatigue. The BHP454, on the other hand, is slightly heavier but compensates with its enhanced power and battery life. Both drills come equipped with a 2-speed mechanical gear system, enabling users to adjust the speed to match the task at hand. This flexibility is essential for both drilling and fastening applications.

A notable technological advancement in these models is the incorporation of brushless motors. The BHP444 and BHP454 utilize Makita's efficient brushless technology, resulting in higher energy efficiency and longer tool life. The absence of brushes reduces friction, which not only enhances power delivery but also minimizes wear, leading to reduced maintenance requirements.

Both models feature a hammer function, allowing users to drill into tough materials such as concrete and masonry. The adjustable torque settings provide precise control for various applications, ensuring consistent results whether working with wood, metal, or concrete. The 13mm keyless chuck prevents bit slippage during operation, allowing for quick bit changes and increased productivity on the job.

Battery performance is another critical aspect of the BHP444 and BHP454. Both drills are compatible with Makita's 18V lithium-ion battery platform, known for its rapid charging capabilities and long runtime. The built-in battery protection circuit helps to extend the lifespan of the battery, making these tools a reliable choice for extended work sessions.

Safety features include an ergonomic handle designed to provide a firm grip and reduce vibration during operation. This design minimizes user fatigue and enhances control, which is crucial for precision work.

In conclusion, the Makita BHP444 and BHP454 hammer drills showcase a blend of power, technology, and user-friendly design. Whether tackling home improvement projects or professional construction tasks, these tools provide the reliability and performance needed to get the job done efficiently.
