IMPORTANT SAFETY

INSTRUCTIONSENC007-7

FOR BATTERY CARTRIDGE

1.Before using battery cartridge, read all instructions and cautionary markings on (1) battery charger, (2) battery, and (3) product using battery.

2.Do not disassemble battery cartridge.

3.If operating time has become excessively shorter, stop operating immediately. It may result in a risk of overheating, possible burns and even an explosion.

4.If electrolyte gets into your eyes, rinse them out with clear water and seek medical attention right away. It may result in loss of your eyesight.

5.Do not short the battery cartridge:

(1)Do not touch the terminals with any conductive material.

(2)Avoid storing battery cartridge in a container with other metal objects such as nails, coins, etc.

(3)Do not expose battery cartridge to water or rain.

A battery short can cause a large current flow, overheating, possible burns and even a breakdown.

6.Do not store the tool and battery cartridge in locations where the temperature may reach or exceed 50°C (122°F).

7.Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. The battery cartridge can explode in a fire.

8.Be careful not to drop or strike battery.

9.Do not use a damaged battery.

SAVE THESE INSTRUCTIONS.

Tips for maintaining maximum battery life

1.Charge the battery cartridge before completely discharged.

Always stop tool operation and charge the battery cartridge when you notice less tool power.

2.Never recharge a fully charged battery cartridge. Overcharging shortens the battery service life.

3.Charge the battery cartridge with room temperature at 10°C - 40°C (50°F - 104°F). Let a hot battery cartridge cool down before charging it.

4.Charge the battery cartridge once in every six months if you do not use it for a long period of time.

FUNCTIONAL DESCRIPTION

CAUTION:

•Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool.

Installing or removing battery cartridge (Fig. 1)

•Always switch off the tool before installing or removing of the battery cartridge.

•To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge.

•To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Always insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely. Install it fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.

•Do not use force when installing the battery cartridge. If the cartridge does not slide in easily, it is not being inserted correctly.

Battery protection system (Lithium-ion battery with star marking) (Fig. 2)

Lithium-ion batteries with a star marking are equipped with a protection system. This system automatically cuts off power to the tool to extend battery life.

The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

• Overloaded:

The tool is operated in a manner that causes it to draw an abnormally high current.

In this situation, release the trigger switch on the tool and stop the application that caused the tool to become overloaded. Then pull the trigger switch again to restart.

If the tool does not start, the battery is overheated. In this situation, let the battery cool before pulling the trigger switch again.

• Low battery voltage:

The remaining battery capacity is too low and the tool will not operate. In this situation, remove and recharge the battery.

Switch action (Fig. 3)

CAUTION:

•Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates

properly and returns to the “OFF” position when released.

To start the tool, simply pull the switch trigger. Tool speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop.

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.
