The MAKITA DFS451 tool is intended for screw driving in wood, metal, and plastic.

1. Hold the power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring. Fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

2. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations.

3. Hold the tool firmly.

4. Keep hands away from rotating parts.

5. Do not touch the bit or the workpiece immediately after operation; they may be extremely hot and could burn your skin.

6. Always secure workpiece in a vise or similar hold-down device.

7. Make sure there are no electrical cables, water pipes, gas pipes etc. that could cause a hazard if damaged by use of the tool.

1. Before using the battery cartridge, read all instructions and cautionary markings on (1) battery charger, (2) battery, and (3) product using battery.

2. Do not disassemble or tamper with the battery cartridge. It may result in a fire, excessive heat, or explosion.

3. If operating time has become excessively shorter, stop operating immediately. It may result in a risk of overheating, possible burns and even an explosion.

4. If electrolyte gets into your eyes, rinse them out with clear water and seek medical attention right away. It may result in loss of your eyesight.

5. Do not short the battery cartridge:

(1) Do not touch the terminals with any conductive material.

(2) Avoid storing battery cartridge in a container with other metal objects such as nails, coins, etc.

(3) Do not expose battery cartridge to water or rain. A battery short can cause a large current flow, overheating, possible burns and even a breakdown.

6. Do not store and use the tool and battery cartridge in locations where the temperature may reach or exceed 50 °C (122 °F).

7. Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. The battery cartridge can explode in a fire.

9. Do not use a damaged battery.

10. The contained lithium-ion batteries are subject to the Dangerous Goods Legislation requirements. For commercial transports e.g. by third parties, forwarding agents, special requirement on packaging and labeling must be observed.

11. When disposing the battery cartridge, remove it from the tool and dispose of it in a safe place. Follow your local regulations relating to disposal of battery.

12. Use the batteries only with the products specified by Makita. Installing the batteries to non-compliant products may result in a fire, excessive heat, explosion, or leak of electrolyte.

13. If the tool is not used for a long period of time, the battery must be removed from the tool.

14. During and after use, the battery cartridge may take on heat which can cause burns or low temperature burns. Pay attention to the handling of hot battery cartridges.

15. Do not touch the terminal of the tool immediately after use as it may get hot enough to cause burns.

16. Do not allow chips, dust, or soil stuck into the terminals, holes, and grooves of the battery cartridge. It may cause heating, catching fire, burst and malfunction of the tool or battery cartridge, resulting in burns or personal injury.

17. Unless the tool supports the use near high-voltage electrical power lines, do not use the battery cartridge near high-voltage electrical power lines. It may result in a malfunction or breakdown of the tool or battery cartridge.

18. Keep the battery away from children.

CAUTION: Only use genuine Makita batteries. Use of non-genuine Makita batteries, or batteries that have been altered, may result in the battery bursting causing fires, personal injury and damage.

1. Charge the battery cartridge before completely discharged. Always stop tool operation and charge the battery cartridge when you notice less tool power.

2. Never recharge a fully charged battery cartridge. Overcharging shortens the battery service life.

3. Charge the battery cartridge with room temperature at 10 °C – 40 °C (50 °F – 104 °F). Let a hot battery cartridge cool down before charging it.

4. When not using the battery cartridge, remove it from the tool or the charger.

5. Charge the battery cartridge if you do not use it for a long period (more than six months).

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

• 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. Always 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. Install it 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.

The MAKITA DFS451 is equipped with a tool/battery protection system that automatically cuts off power to extend tool and battery life. The tool will stop if it or the battery is placed under one of the following conditions:

Overload protection: This activates when the tool draws an abnormally high current. To reset, turn the tool off, stop the application that caused the overload, and then turn the tool on again.

Overheat protection: This activates when the tool or battery overheats. In this situation, allow the tool and battery to cool down before turning the tool on again.

Overdischarge protection: This activates when the remaining battery capacity is low. When this happens, remove the battery from the tool and charge it.

This feature is available only for battery cartridges with an indicator. Press the check button on the battery cartridge to see the remaining capacity. The indicator lamps will light up for a few seconds.

NOTE:

• Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.

• The first (far left) indicator lamp will blink when the battery protection system works.

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. The tool’s speed increases with more pressure on the switch trigger. Release the switch trigger to stop.

NOTE: Even with the switch on and motor running, the bit will not rotate until you fit the point of the bit in the screw head and apply forward pressure to engage the clutch.

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 remains lit while the switch trigger is being pulled. The lamp will go out 10 – 15 seconds after releasing the trigger.

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

The MAKITA DFS451 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.

The screwdriving depth can be adjusted by turning the locator.

• Turn it in the “B” direction for less depth.

• Turn it in the “A” direction for more depth.

One full turn of the locator equals a 2 mm change in depth.

Adjust the locator so that the distance between the tip of the locator and the screw head is approximately 3 mm. Drive a trial screw into your material or a piece of duplicate material. If the depth is still not suitable for the screw, continue adjusting until you obtain the proper depth setting.

To remove the bit:

1. Pull the locator off.

2. Grasp the bit with a pair of pliers and pull it out of the magnetic bit holder. It may help to wiggle the bit with the pliers as you pull.

To install the bit:

1. Push the bit firmly into the magnetic bit holder.

2. Install the locator by pushing it firmly back.

WARNING:

• Use the hanging/mounting parts for their intended purposes only, e.g., hanging the tool on a tool belt between jobs or work intervals.

• Be careful not to overload the hook as too much force or irregular overburden may cause damages to the tool resulting in personal injury.

CAUTION:

• When installing the hook, always secure it with the screw firmly. If not, the hook may come off from the tool and result in the personal injury.

• Make sure to hang the tool securely before releasing your hold. Insufficient or unbalanced hooking may cause falling off and you may be injured.

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

1. Fit the screw on the point of the bit.

2. Place the point of the screw on the surface of the workpiece to be fastened.

3. Apply pressure to the tool and start it by pulling the switch trigger.

4. Withdraw the tool as soon as the clutch cuts in, then release the switch trigger.

CAUTION:

• When fitting the screw onto the point of the bit, be careful not to push in on the screw. If the screw is pushed in, the clutch will engage and the screw will rotate suddenly. This could damage a workpiece or cause an injury.

• Make sure that the bit is inserted straight in the screw head, or the screw and/or bit may be damaged.

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.

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