Safety Information

Always observe basic safety precautions when using power tools to reduce the risk of fire, electric shock, and personal injury. Read all instructions carefully before operation.

• Work Area Safety: Keep your work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
• Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Do not expose power tools to rain or wet conditions.
• Personal Safety: Always wear eye protection. Use hearing protection when operating the drill in hammer mode or for extended periods. Dress properly; avoid loose clothing or jewelry.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
• Battery Compatibility: The DHP487Z is designed for 18V Li-ion LXT slide type batteries. It is not compatible with G-Series batteries. Use of non-genuine or compatible batteries and chargers will invalidate the Makita guarantee.

Setup

1. Battery Installation and Removal

The DHP487Z uses 18V Li-ion LXT slide-type batteries. Ensure the battery is fully charged before use.

• To Install: Align the battery pack with the groove in the tool's handle and slide it in until it clicks into place. Ensure it is securely latched.
• To Remove: Press the release button on the battery pack and slide the battery out of the tool.

2. Bit Installation (Single Sleeve Keyless Chuck)

The drill features a single sleeve keyless chuck for quick and easy bit changes.

1. To open the chuck jaws, hold the chuck body and rotate the sleeve counter-clockwise.
2. Insert the drill bit or screwdriver bit fully into the chuck.
3. To tighten, hold the chuck body and rotate the sleeve clockwise until the bit is firmly secured. A clicking sound may indicate the chuck is fully tightened.

Operating Instructions

1. Power On/Off and Variable Speed Control

The trigger switch controls the tool's operation and speed.

• To start the tool, pull the trigger switch. The tool speed increases with increasing pressure on the trigger switch.
• To stop the tool, release the trigger switch.

2. Forward/Reverse Rotation

The forward/reverse switch is located above the trigger. Push the lever from either side to select rotation direction.

• For forward rotation (clockwise), push the lever from the right side.
• For reverse rotation (counter-clockwise), push the lever from the left side.
• When the lever is in the center position, the trigger switch is locked, preventing accidental startup.

3. Mechanical Gear Selection (2-Speed)

The DHP487Z features two mechanical gears for optimal performance in different applications.

• High Speed Mode (Gear 2): For speedy drilling in light-duty applications. Select this gear by sliding the gear selector switch to the "2" position.
• Low Speed Mode (Gear 1): For heavy-duty applications requiring high torque, such as driving large screws or drilling large holes. Select this gear by sliding the gear selector switch to the "1" position.
• Always ensure the tool is stopped before changing gear settings to prevent damage.

4. Torque Settings and Drill Mode

The torque setting ring allows you to adjust the clutch to prevent over-tightening screws or damaging materials. The drill also has a dedicated drill mode and hammer drill mode.

• Torque Settings (1-20): Rotate the ring to select one of the 20 torque settings. Lower numbers provide less torque, suitable for smaller screws or softer materials. Higher numbers provide more torque.
• Drill Mode (⚙ symbol): For general drilling applications without clutch action. The drill will operate at full torque.
• Hammer Drill Mode (⚒ symbol): For drilling into masonry materials. This mode engages the hammer mechanism for impact drilling.
