NOTE:

 Depending on the conditions of use and the 

ambient temperature, the indication may differ slightly 

from the actual capacity.

NOTE:

 The first (far left) indicator lamp will blink when 

the battery protection system works.

Tool / battery protection system

The tool is equipped with a tool/battery protection system. This 

system automatically cuts off power to the motor to extend tool and 

battery life. The tool will automatically stop during operation if the 

tool or battery is placed under one of the following conditions:

Overload protection

When the tool/battery is operated in a manner that 

causes it to draw an abnormally high current, the tool 

stops automatically. In this situation, turn the tool off 

and stop the application that caused the tool to become 

overloaded. Then turn the tool on to restart.

Overheat protection

When the tool/battery is overheated, the tool stops 

automatically and the lamp will blink. In this situation, let 

the tool cool down before turning the tool on again.

Overdischarge protection

When the battery capacity is not enough, the tool stops 

automatically. In this case, remove the battery from the 

tool and charge the battery.

Switch action

CAUTION:

Before installing the battery car-

tridge into the tool, always check to see that the 

switch trigger actuates properly and returns to 

the "OFF" position when released.

 Switch trigger

To start the tool, pull the switch trigger. Tool speed is 

increased by increasing pressure on the switch trigger. 

Release the switch trigger to stop.

NOTE:

 The tool automatically stops if you keep pull-

ing the switch trigger for about 6 minutes.

Lighting up the front lamp

CAUTION:

Do not look in the light or see the 

source of light directly.

 Lamp

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 approximately 10 seconds after 

releasing the switch trigger.

NOTE:

 When the tool is overheated, the tool stops 

automatically and the lamp starts flashing. In this 

case, release the switch trigger. The lamp turns off in 

1 minute(s).

NOTE:

 Use a dry cloth to wipe the dirt off the lens of 

the lamp. Be careful not to scratch the lens of lamp, or 

it may lower the illumination.

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 dam-

age the tool.

CAUTION:

When not operating the tool, 

always set the reversing switch lever to the neu-

tral position.

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 coun-

terclockwise rotation.

When the reversing switch lever is in the neutral posi-

tion, the switch lever cannot be pulled.

Speed change

NOTICE:

Use the speed change knob only after 

the tool comes to a complete stop.

 Changing the 

tool speed before the tool stops may damage the tool.

NOTICE:

Always set the speed change knob 

carefully into the correct position.

 If you operate 

the tool with the speed change knob positioned half-

way between the position 1 and the position 2, the 

tool may be damaged.

NOTICE:

If the rotation speed significantly 

decreases during operation in the high speed 

mode, stop the tool and change the mode to the 

low speed mode.

 Otherwise, the motor may get 

overloaded and cause a malfunction or fire.

Two speed ranges can be preselected with the speed 

change knob.

To change the speed, turn the speed change knob so 

that the pointer points to the position 1 for low speed 

mode or the position 2 for high speed mode.

Electronic function

Electric brake

This tool is equipped with an electric brake. If the tool 

consistently fails to quickly cease to function after the 

switch trigger is released, have the tool serviced at a 

Makita service center.

Soft start feature

This function allows the smooth start-up of the tool by 

limiting the start-up torque.
