FUNCTIONAL DESCRIPTION

CAUTION:

- Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool.

Installing or removing battery cartridge (Fig. 1)

CAUTION:

- Always switch off the tool before installing or removing of the battery cartridge.

To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge.

To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely.

CAUTION:

• Always install the battery cartridge fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.
- Do not use force when installing the battery cartridge. If the cartridge does not slide in easily, it is not being inserted correctly.

Battery protection system (Lithium-ion battery with star marking) (Fig. 2)

Lithium-ion batteries with a star marking are equipped with a protection system. This system automatically cuts off power to the tool to extend battery life.

The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

- Overloaded:

The tool is operated in a manner that causes it to draw an abnormally high current.

In this situation, release the switch trigger on the tool and stop the application that caused the tool to become overloaded. Then pull the switch trigger again to restart.

If the tool does not start, the battery is overheated. In this situation, let the battery cool before pulling the switch trigger again.

- Low battery voltage:

The remaining battery capacity is too low and the tool will not operate. In this situation, remove and recharge the battery.

Switch action (Fig. 3)

CAUTION:

- Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released.

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.

Lighting up the front lamp (Fig. 4)

CAUTION:

- Do not look in the light or see the source of light directly.

Pull the switch trigger to light up the lamp. The lamp keeps on lighting while the switch trigger is being pulled.

The lamp goes out 10 -15 seconds after releasing the trigger.

NOTE:

- Use a dry cloth to wipe the dirt off the lens of lamp. Be careful not to scratch the lens of lamp, or it may lower the illumination.

Reversing switch action (Fig. 5)

This tool has a reversing switch to change the direction of rotation. Depress the reversing switch lever from the A side for clockwise rotation or from the B side for counterclockwise rotation.

When the reversing switch lever is in the neutral position, the switch trigger cannot be pulled.

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.
• When not operating the tool, always set the reversing switch lever to the neutral position.

Speed change (Fig. 6)

To change the speed, first switch off the tool and then slide the speed change lever to the "2" side for high speed or, "1" side for low speed. Be sure that the speed change lever is set to the correct position before operation. Use the right speed for your job.

CAUTION:

• Always set the speed change lever fully to the correct position. If you operate the tool with the speed change lever positioned halfway between the "1" side and, "2" side, the tool may be damaged.
• Do not use the speed change lever while the tool is running. The tool may be damaged.

Selecting the action mode (Fig. 7)

This tool has an action mode changing ring. For drilling, turn the ring so that the arrow on the tool body points toward the mark on the ring. For screwing, turn the ring so that the arrow points toward the mark on the ring.

CAUTION:

- Always set the ring correctly to your desired mode mark. If you operate the tool with the ring positioned halfway between the mode marks, the tool may be damaged.

Adjusting the fastening torque (screwdriver mode “”) (Fig. 8)

The fastening torque can be adjusted in 21 steps by turning the adjusting ring so that its graduations are aligned with the pointer on the tool body. First, slide the action mode change lever to the position of symbol.

The fastening torque is minimum when the number 1 is aligned with the pointer, and maximum when the marking is aligned with the pointer. The clutch will slip at various torque levels when set at the number 1 to 21. Before actual operation, drive a trial screw into your material or a piece of duplicate material to determine which torque level is required for a particular application.

NOTE:

- The adjusting ring does not lock when the pointer is positioned only halfway between the graduations.

Empty signal for remaining battery capacity (Fig. 9)

Stop the tool and with the tool stopped press the button on the switch panel and the remaining battery capacity will be signaled on the panel.

The status displayed on the switch panel and the remaining battery capacity is shown in the following table.

LED indicator status Remaining battery capacity
	About 50 % or more
	About 20 % - 50 %
	About less than 20 %

012023

NOTE:

- Before checking the remaining battery capacity, be sure to stop the tool.

ASSEMBLY

CAUTION:

- Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

Installing side grip (auxiliary handle) (Fig. 10)

Always use the side grip to ensure operating safety. Insert the side grip so that the protrusions on the grip base and steel band fit in between the grooves on the tool barrel. Then tighten the grip by turning clockwise. To change the angle of the side grip, loosen and remove the grip, then turn and insert it again.

Installing or removing driver bit or drill bit (Fig. 11)

Turn the sleeve counterclockwise to open the chuck jaws. Place the bit in the chuck as far as it will go. Turn the sleeve clockwise to tighten the chuck. To remove the bit, turn the sleeve counterclockwise.

Installing bit holder (Fig. 12)

Fit the bit holder into the protrusion at the tool foot on either right or left side and secure it with a screw. When not using the driver bit, keep it in the bit holders. Bits 45 mm long can be kept there.

Hook (Fig. 13)

The hook is convenient for temporarily hanging the tool. This can be installed on either side of the tool.

To install the hook, insert it into a groove in the tool housing on either side and then secure it with a screw. To remove, loosen the screw and then take it out.

OPERATION (Fig. 14)

Screwdriving operation

First, slide the action mode change lever so that it points to the marking. Adjust the adjusting ring to the proper torque level for your work. Then proceed as follows. Place the point of the driver bit in the screw head and apply pressure to the tool. Start the tool slowly and then increase the speed gradually. Release the switch trigger as soon as the clutch cuts in.

NOTE:

• Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged.
• When driving wood screw, predrill a pilot hole 2/3 the diameter of the screw. It makes driving easier and prevents splitting of the workpiece.
• If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.

Drilling operation

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 bit into the workpiece.

Drilling in 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. The exceptions are iron and brass which should be drilled dry. First, slide the action mode change lever so that it points to the 1 marking. The adjusting ring can be aligned in any torque levels for this operation. Then proceed as follows.

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 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.
• 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.
• If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
- Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

Replacing carbon brushes (Fig. 15)

Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes.

Use a screwdriver to remove two screws then remove the rear cover. (Fig. 16)

Raise the arm part of the spring and then place it in the recessed part of the brush holder with a slotted bit screwdriver of slender shaft or the like. (Fig. 17)

Use pliers to remove the carbon brush caps of the carbon brushes. Take out the worn carbon brushes, insert the new ones. (Fig. 18)

Make sure that the carbon brush caps fit into the holes in brush holders securely.

Reinstall the rear cover and tighten two screws securely. (Fig. 19)

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