What are the electrical safety guidelines for using power tools?

Double insulated tools are equipped with a polarized plug. If the plug does not fit fully in the outlet, reverse the plug; if it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. Do not expose power tools to rain or wet conditions. Do not abuse the cord, and keep it away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”.

What should I know about using extension cords with power tools?

Make sure the extension cord is in good condition. Use a cord heavy enough to carry the current the product will draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge; the smaller the gauge number, the heavier the cord.

What are some important points about personal safety when using power tools?

Hold tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Always be sure to have a firm footing. Be sure no one is below when using the tool in high locations. Hold the tool firmly with both hands and always use the side grip. Keep hands away from rotating parts. Do not leave the tool running and operate it only when hand-held. Do not touch the bit or the workpiece immediately after operation, as they may be extremely hot and could burn the skin. Take caution to prevent working dust inhalation and skin contact, as some materials contain chemicals which may be toxic; follow material supplier safety data.

---

How should I handle the tool itself for safe and effective use?

Use clamps or another practical way to secure and support the workpiece to a stable platform. Do not force the tool and use the correct tool for the application. Do not use the tool if the switch does not turn it on or off. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Store idle tools out of reach of children and other untrained persons. Maintain tools with care and keep cutting tools sharp and clean. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation; if damaged, have the tool serviced before using. Use only accessories that are recommended by the manufacturer for the model.

---

What should I check before plugging in the tool?

Always check to see that the switch trigger actuates properly and returns to the “OFF” position when released. The switch can be locked in the “ON” position for ease of operator comfort during extended use, but apply caution when locking the tool in the “ON” position and maintain a firm grasp on the tool.

---

How do I start and stop the tool?

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. For continuous operation, pull the switch trigger and then push in the lock button. To stop the tool from the locked position, pull the switch trigger fully, then release it.

---

How do I adjust the speed of the tool?

A speed adjusting dial is provided so that the maximum tool speed can be limited (variable). Turn the speed adjusting dial clockwise for higher speed and counterclockwise for lower speed.

---

How does the reversing switch work?

The tool has a reversing switch to change the direction of rotation. Move the reversing switch lever to the position (A side) for clockwise rotation or the position (B side) for counterclockwise rotation. Always check the direction of rotation before operation. Use the reversing switch only after the tool comes to a complete stop, as changing the direction of rotation before the tool stops may damage it. If the switch trigger cannot be depressed, check to see that the reversing switch is fully set to position (A side) or (B side).

---

How do I change the speed range of the tool?

Two speed ranges can be preselected with the speed change knob. To change the speed, turn the speed change knob so that the arrow on the tool body points toward the “I” position on the knob for low speed or “II” position for high speed. If it is hard to turn the knob, first turn the chuck slightly in either direction and then turn the knob again. Use the speed change knob only after the tool comes to a complete stop, as changing the tool speed before the tool stops may damage the tool. Always set the speed change knob to the correct position; if you operate the tool with the speed change knob positioned halfway between the “I” and “II” position, the tool may be damaged.

---

How do I select the action mode (rotation with hammering or rotation only)?

This tool has an action mode change lever. For rotation with hammering, slide the action mode change lever to the right ( symbol). For rotation only, slide the action mode change lever to the left ( symbol). Always slide the action mode change lever all the way to the desired mode position; if you operate the tool with the lever positioned halfway between the mode symbols, the tool may be damaged.

---

How do I install the side grip (auxiliary handle)?

Always use the side grip to ensure operating safety. Install the side grip so that the teeth on the grip fit in between the protrusions on the tool barrel. Then, tighten the grip by turning clockwise at the desired position; it may be swung 360° so as to be secured at any position.

---

How do I install or remove a drill bit?

For Model HP2070, HP2070F: Place the bit in the chuck as far as it will go and tighten the chuck by hand. Place the chuck key in each of the three holes and tighten clockwise, ensuring all three chuck holes are tightened evenly. To remove the bit, turn the chuck key counterclockwise in just one hole, then loosen the chuck by hand. After using the chuck key, be sure to return it to its original position. For Model HP2071, HP2071F: Hold the ring and turn the sleeve counterclockwise to open the chuck jaws. Place the bit in the chuck as far as it will go. Hold the ring firmly and turn the sleeve clockwise to tighten the chuck. To remove the bit, hold the ring and turn the sleeve counter-clockwise.

---

What should I do if the keyless drill chuck cannot be loosened?

Hold the sleeve of the drill chuck firmly with water pump pliers or the like (Note: Do not hold the retaining ring portion). Place the wrench 19, adjustable wrench, or one of other appropriate wrenches on the hexagonal nut at the front of the drill chuck. Turn the wrench clockwise to loosen the drill chuck.

---

How do I use the depth gauge?

Loosen the side grip and insert the depth gauge into the hole in the side grip. Adjust the depth gauge to the desired depth and tighten the side grip. The depth gauge cannot be used at the position where it strikes against the tool body.

---

How do I perform hammer drilling operation?

When drilling in concrete, granite, tile, etc., move the action mode changing lever to the position of symbol to use “rotation with hammering” action. Be sure to use a tungsten-carbide tipped bit. Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool; light pressure gives the best results. Keep the tool in position and prevent it from slipping away from the hole. Do not apply more pressure when the hole becomes clogged with chips or particles; instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Failure to do so may result in the loss of control of the tool and potentially severe injury. There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete.

---

How do I use the tool for standard drilling?

When drilling in wood, metal, or plastic materials, move the action mode changing lever to the position of symbol to use “rotation only” action.

---

What is the best way to drill into wood?

When drilling in wood, the best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece.

---

How do I drill into metal?

To prevent the bit from slipping when starting a hole, make an indentation with a center-punch and hammer at the point to be drilled. Place the point of the bit in the indentation and start drilling. Use a cutting lubricant when drilling metals, except for iron and brass, which should be drilled dry.

---

What should I avoid when drilling?

Pressing excessively on the tool will not speed up drilling and will only damage the tip of the bit, decrease tool performance, and shorten the tool’s service life. There is a tremendous force exerted on the tool/bit at the time of hole break through; hold the tool firmly and exert care when the bit begins to break through the workpiece.

---

What should I do if the bit gets stuck?

A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool may back out abruptly if it is not held firmly.

---

What is the importance of securing workpieces?

Always secure small workpieces in a vise or similar hold-down device.

---

What does the indicator lamp tell me?

The green power-ON indicator lamp lights up when the tool is switched ON. If the indicator lamp is lit but the tool does not start, the carbon brushes may be worn out, or the electric circuit or the motor may be defective. If the indicator lamp does not light up and the tool does not start, the ON/OFF switch or the mains cord may be defective. The red service indicator lamp lights up when the tool is excessively loaded. Continued operation under such a condition will result in a failure or breakage of the tool; cool down the tool by running it under no load.

---

How do I maintain the tool?

The tool and its air vents have to be kept clean. Regularly clean the tool’s air vents or whenever the vents start to become obstructed.

---

Where should I go for repairs and maintenance?

To maintain product safety and reliability, repairs, carbon brush inspection and replacement, and any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.

---

What accessories are recommended for use with the tool?

Drill bits, hammer drill bits, hole saws, blow-out bulb, safety goggles, chuck key, grip assembly, depth gauge, and plastic carrying case. Only use an accessory or attachment for its stated purpose. The use of any other accessories or attachments might present a risk of injury to persons.

What are some potential hazards associated with power tool use?

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. Examples of these chemicals include lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically-treated lumber. To reduce exposure to these chemicals, work in a well-ventilated area and with approved safety equipment, such as dust masks specially designed to filter out microscopic particles.
