SAVE THESE INSTRUCTIONS.

OPERATING INSTRUCTIONS

CAUTION:

- Always be sure that the tool is switched off and unplugged before installing or removing the side grip, bit or other accessories.

Installing the side grip (Fig.1)

Always install the side grip on the tool and hold the tool firmly with both hands during operation. The side grip swings around to either side, allowing easy handling of the tool in any position. Swing it to the desired position and secure it by turning clockwise.

NOTE:

The side grip cannot swing 360^ when the depth gauge is installed.

Installing or removing the drill bit

For Model 8450, 8452

To install the bit, place it in the 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 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 the original position.

For Model 8451 (Fig.2)

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 counterclockwise.

Depth gauge (Fig.3)

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 side grip. Adjust the depth gauge to the desired depth and tighten the side grip.

Switch action (Fig.4)

For Model 8450, 8451

To start the tool, simply pull the trigger. Tool speed is increased by increasing pressure on the trigger. Release the trigger to stop. For continuous operation, pull the trigger and then push in the lock button. To stop the tool from the locked position, pull the trigger fully, then release it.

For Model 8452

To start the tool, simply pull the trigger. Tool speed is increased by increasing pressure on the trigger. Release the trigger to stop. For continuous operation, pull the trigger and then push in the lock button. To stop the tool while in the locked position, pull the trigger fully, then release it.

Reversing switch (Fig.5)

For Model 8450, 8451

These tools have a reversing switch to change the direction of rotation. Move the reversing switch lever to the ↑ position for clockwise rotation or the ↓ position for counterclockwise rotation.

CAUTION:

• Always check the direction of rotation before operation.
• 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.
• 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 you do not hold it firmly.

For ALL MODELS

CAUTION:

Before plugging the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released.

Action mode (Fig.6)

This tool employs the action mode changing buttons. For rotation only, press the button on the ▲▼▼ mark side fully. For rotation with hammering, press the button on the ⏱ mark side fully.

CAUTION:

Be sure to press the action mode changing button as far as it will go. Failure to do so may cause malfunction of the tool.

Operation (Fig.7)

1) Hammer drilling operation

When drilling in concrete, granite, tile, etc., press the button on the ⚡ mark side fully. Be sure to use a tungsten-carbide tipped 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 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.

2) Drilling operation

When drilling in wood, metal or plastic materials, press the button on the ▲▶ mark side fully. Drilling in wood

When drilling in wood, 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.

Drilling in metal

To prevent the bit from slipping when starting a hole, make an indentation with a centerpunch 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. The exceptions are iron and brass which should be drilled dry.

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 bit, decrease the tool performance and shorten the service life of the tool.
• There is a tremendous twisting force exerted on the tool/bit at the time of hole breakthrough. Hold the tool firmly and exert care when the bit begins to breakthrough the workpiece. Use both hands to help control the tool. Be sure to use the side grip to maintain proper control.
• 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 you do not hold it firmly.
• Always secure small workpieces in a vise or similar hold-down device.

MAINTENANCE

CAUTION:

Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.

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