Safety instructions for all operations

1. Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
2. Use the auxiliary handle(s). Loss of control can cause personal
3. Hold the power tool by insulated gripping sur­ faces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. 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. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations.
5. Hold the tool firmly with both hands.
6. Keep hands away from rotating parts.
7. Do not leave the tool running. Operate the tool only when hand-held.
8. Do not touch the drill bit or the workpiece immediately after operation; they may be extremely hot and could burn your skin.
9. Some material contains chemicals that may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
10. If the drill bit cannot be loosened even if you open the jaws, use pliers to pull it out. In such a case, pulling out the drill bit by hand may result in injury by its sharp edge.

Safety instructions when using long drill bits

1. Never operate at a higher speed than the maximum speed rating of the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
2. Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
3. Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend causing breakage or loss of control, resulting in personal injury.

SAVE THESE INSTRUCTIONS.

WARNING: DO NOT let comfort or familiarity with the product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to  follow the safety rules stated in this instruction manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking the function on the tool.

Switch action

WARNING: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.

► Fig.1: 1. Switch trigger 2. Lock button
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, push in the lock button and then release the switch trigger. To stop the tool from the locked position, pull the switch trigger fully, then release it.

CAUTION: Switch can be locked in the “ON” position for ease of operator comfort during extended use. Apply caution when locking the tool in the “ON” position and maintain a firm grasp on tool.

Reversing switch action

CAUTION: Always check the direction of rotation before operation.
CAUTION: Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool.

► Fig.2: 1. Reversing switch lever This 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 to the position (B side) for counterclockwise rotation.

Selecting the action mode

CAUTION: Always slide the action mode changing lever all the way to your desired mode position. If you operate the tool with the lever positioned halfway between the mode symbols, the tool may be damaged.

► Fig.3: 1. Action mode changing lever This tool has an action mode changing lever. For rotation with hammering, slide the action mode changing lever to the right ( symbol).  For rotation only, slide the action mode changing lever to the left ( symbol).

ASSEMBLY

Installing or removing the drill bit

CAUTION: Always be sure that the tool is switched off and unplugged before installing or removing the drill bit.

For model M8100
► Fig.5: 1. Drill chuck 2. Chuck key
To install the drill bit, place it in the drill chuck as far as it will go. Tighten the chuck by hand. Place the chuck key in each of the three holes and tighten clockwise. Be sure to tighten all three chuck holes evenly.
To remove the drill bit, turn the drill chuck key counterclockwise in just one hole, then loosen the chuck by hand.
After using the chuck key, be sure to return it to the original position.

For model M8101
► Fig.6: 1. Sleeve 2. Ring
Hold the ring and turn the sleeve counterclockwise to open the chuck jaws. Place the drill bit in the drill chuck as far as it will go. Hold the ring firmly and turn the sleeve clockwise to tighten the chuck.
To remove the drill bit, hold the ring and turn the sleeve counterclockwise.

Depth gauge

The depth gauge is convenient for drilling holes of uniform depth. Loosen the side grip and insert the depth gauge into the hole in the grip base. Adjust the depth gauge to the desired depth and tighten the side grip firmly.
NOTE: The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing.

OPERATION

CAUTION: Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations.
► Fig.8

Hammer drilling operation

CAUTION: It is a tremendous and sudden twisting force exerted on the tool/drill bit at the time of hole breakthrough, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. 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.

When drilling in concrete, granite, tile, etc., slide the action mode changing lever to the position of the symbol to use the “rotation with hammering” action. Be sure to use a tungsten-carbide-tipped drill bit. Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the drill bit partially from the hole. By repeating this several times, the hole will be cleaned out. After drilling the hole, use the blow-out bulb to clean the dust out of the hole.

Drilling operation

CAUTION: Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your drill bit, decrease the tool performance and shorten the service life of the tool.
CAUTION: Hold the tool firmly and exert care when the drill bit begins to break through the workpiece. There is a tremendous force exerted on the tool/drill bit at the time of hole breakthrough.
CAUTION: A stuck drill 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 you do not hold it firmly.
CAUTION: Always secure workpieces in a vise or similar hold-down device.

When drilling in wood, metal or plastic materials, slide the action mode changing lever to the position of the symbol to use “rotation only” action.
Drilling in 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 drill bit into the workpiece.
Drilling in metal
To prevent the drill 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 drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry.

MAINTENANCE

CAUTION: Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
NOTICE: Never use gasoline, benzene, thinner, alcohol, or the like. Discoloration, deformation, or cracks may result.

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