What is the intended use of the Makita M8100 and M8101 hammer drills?

These tools are designed for impact drilling in brick, concrete, and stone. They can also be used for drilling without impact in wood, metal, ceramic, and plastic.

---

What type of power supply should be used for these drills?

The tool should only be connected to a power supply of the same voltage as indicated on its nameplate. It operates on a single-phase AC supply and is double-insulated, meaning it can be used from sockets without an earth wire.

What safety precautions should be taken regarding noise levels?

• Sound pressure level (LpA): 98 dB(A)
• Sound power level (LWA): 109 dB(A)
• Uncertainty (K): 3 dB(A)
• Warning: Always wear ear protection when using the tool, as actual noise emission may vary depending on the workpiece and conditions of use.

---

What are the vibration levels for the Makita M8100 and M8101?

• Impact drilling into concrete:

  • Vibration emission (ah,ID): 16.5 m/s²
  • Uncertainty (K): 2.0 m/s²

• Drilling into metal:

  • Vibration emission (ah,D): 3.0 m/s²
  • Uncertainty (K): 1.5 m/s²

• Warning: The vibration levels may vary depending on how the tool is used and the workpiece being drilled. Safety measures should be taken to minimize exposure.

What are the general safety warnings for using the hammer drill?

• Read all safety warnings, instructions, illustrations, and specifications before use.
• Keep the work area clean and well-lit.
• Do not operate in explosive atmospheres.
• Keep children and bystanders away.
• Ensure power tool plugs match the outlet and never modify them.
• Avoid contact with grounded surfaces like pipes and radiators.
• Do not expose the tool to rain or wet conditions.
• Do not abuse the power cord.
• Use an outdoor-rated extension cord when operating outdoors.
• Use a Residual Current Device (RCD) when working in damp locations.
• Stay alert and avoid using the tool when tired or under the influence of substances.
• Wear appropriate personal protective equipment, including safety goggles, hearing protection, and dust masks when necessary.

How does the switch trigger function?

• To start the tool, pull the switch trigger.
• Speed increases with the pressure applied to the trigger.
• Release the trigger to stop the tool.
• For continuous operation, pull the switch trigger, push the lock button, and then release the trigger. To stop, pull the switch trigger fully and release it.
• Caution: The switch can be locked in the “ON” position for operator comfort, but this should be used carefully.

---

How does the reversing switch function?

• Move the reversing switch lever to the A-side for clockwise rotation.
• Move the reversing switch lever to the B-side for counterclockwise rotation.
• Caution: Always stop the tool completely before changing the direction of rotation to prevent damage.

---

How do you select the action mode?

• Use the action mode changing lever to select the desired operation:
  • Slide it to the right (hammer symbol) for rotation with hammering.
  • Slide it to the left (drill symbol) for rotation only.
• Caution: Always fully move the lever to the desired mode position to avoid damaging the tool.

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

1. Ensure the tool is switched off and unplugged.
2. Align the teeth on the side grip with the protrusions on the tool barrel.
3. Tighten the grip by turning it clockwise to the desired position.
4. The grip can be adjusted 360° for optimal positioning.

How do you install or remove a drill bit?

• For model M8100:

  1. Insert the drill bit into the chuck as far as it will go.
  2. Tighten the chuck by hand.
  3. Use the chuck key in all three holes to evenly tighten it.
  4. To remove, use the chuck key to loosen the chuck counterclockwise.

• For model M8101:

  1. Hold the ring and turn the sleeve counterclockwise to open the chuck.
  2. Insert the drill bit fully.
  3. Hold the ring and turn the sleeve clockwise to tighten.
  4. To remove, hold the ring and turn the sleeve counterclockwise.

---

How do you use the depth gauge?

1. Loosen the side grip.
2. Insert the depth gauge into the hole in the grip base.
3. Adjust to the desired drilling depth.
4. Tighten the side grip firmly.

• Note: The depth gauge cannot be used if it strikes against the gear housing.

---

How do you operate the hammer drilling mode?

1. Slide the action mode changing lever to the hammer drilling position.
2. Use a tungsten-carbide tipped drill bit.
3. Apply firm pressure, but do not force the drill.
4. If chips clog the hole, run the drill at idle and partially remove the drill bit to clear debris.
5. Use a blow-out bulb to clean dust from the hole.

• Caution: Sudden twisting forces may occur during hole break-through or if the hole becomes clogged. Always use the side grip and hold the tool firmly.

---

How do you operate the standard drilling mode?

1. Slide the action mode changing lever to the rotation only position.
2. Secure the workpiece in a vise or similar hold-down device.
3. Use an appropriate drill bit for the material being drilled.
4. Apply steady pressure but do not force the drill.

• Drilling in wood: Use wood drills with a guide screw to ease drilling.
• Drilling in metal: Use a center punch to make an indentation before drilling. Apply cutting lubricant except for iron and brass, which should be drilled dry.

How should you maintain the Makita M8100 and M8101 drills?

• Always turn off and unplug the tool before maintenance.
• Never use gasoline, benzine, thinner, or alcohol for cleaning, as they may cause discoloration or cracks.
• For safety and reliability, repairs and inspections should be performed by Makita Authorized or Factory Service Centers using genuine Makita replacement parts.
