Fig.2: 1. Indicator lamps 2. Check button Press the check button on the battery cartridge to indicate the remaining battery capacity. The indicator lamps light up for a few seconds. makita-DHR400ZKU-Cordless-Rotary-Hammer-
fig-31

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

Tool / battery protection system

The tool is equipped with a tool/battery protection sys-tem. This system automatically cuts off power to the motor to extend tool and battery life. The tool will auto-matically stop during operation if the tool or battery is placed under one of the following conditions:

Overload protection
When the battery is operated in a manner that causes it to draw an abnormally high current, the tool automat-ically stops without any indication. 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 or battery is overheated, the tool stops automatically and the lamp blinks. In this case, let the tool and battery cool 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

WARNING: 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.

CAUTION: When not operating the tool, depress the trigger-lock button lock from side to lock the switch trigger in the OFF position.
► Fig.3: 1. Switch trigger 2. Trigger-lock button makita-DHR400ZKU-Cordless-
Rotary-Hammer-fig-4

To prevent the switch trigger from accidentally pulled, the trigger-lock button is provided. To start the tool, depress the trigger-lock button from A side and pull the switch trigger. Release the switch trigger to stop. After use, press in the trigger-lock button from B side.

Speed change

The revolutions and blows per minute can be adjusted by turning the adjusting dial. The dial is marked 1 (lowest speed) to 5 (full speed). ► Fig.4: 1. Adjusting dial Refer to the table below for the relationship between the number on the adjusting dial and the revolutions and blows per minute.

Number| Revolutions per minute| Blows per minute
---|---|---
5| 500| 2,900
4| 470| 2,700
3| 380| 2,150
2| 290| 1,650
1| 250| 1,450

CAUTION: Do not turn the adjusting dial when the tool is running. Failure to do so may result in the loss of control of the tool and cause an injury.
NOTICE: If the tool is operated continuously at low speed for a long time, the motor will get over-loaded, resulting in tool malfunction.
NOTICE: The speed adjusting dial can be turned only as far as 5 and back to 1. Do not force it past 5 or 1, or the speed adjusting function may no longer work.
NOTE: When the speed adjusting dial is set to “3” or higher, the tool automatically reduces the speed at
no-load to reduce the vibration under no-load. Once operation starts with a bit against concrete, blows per minute increase and reach the numbers as shown in the table. When temperature is low and there is less fluidity in grease, the tool may not have this function even with the motor rotating.

Lighting up the front lamp

Fig.5: 1. Lamp

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 approximately 10 seconds after releasing the switch trigger.
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.

Selecting the action mode

NOTICE: Do not rotate the action mode chang-ing knob when the tool is running. The tool will be damaged.
NOTICE: To avoid rapid wear on the mode change mechanism, be sure that the action mode changing knob is always positively located in one of the three action mode positions.

Rotation with hammering
For drilling in concrete, masonry, etc., rotate the action mode changing knob to the symbol. Use a carbide- tipped drill bit. ► Fig.6: 1. Action mode changing knob 2. Pointer

Hammering only
For chipping, scaling or demolition operations, rotate the action mode changing knob to the symbol. Use a bull point, cold chisel, scaling chisel, etc. ► Fig.7: 1. Pointer 2. Action mode changing knob

Torque limiter

NOTICE: As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool.
NOTICE: Drill bits such as hole saw, which tend to pinch or catch easily in the hole, are not appropriate for this tool. This is because they will cause the torque limiter to actuate too frequently.

The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the output shaft. When this happens, the drill bit will stop turning.

Constant speed control

Electronic speed control for obtaining constant speed. Possible to get fine finish, because the rotating speed is kept constant even under load condition.

Hammer drilling operation

CAUTION: There is tremendous and sudden twisting force exerted on the tool/drill bit at the time of hole break-through, when the hole becomes cloggedwith 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 opera- tions. Failure to do so may result in the loss of control of the tool and potentially severe injury. Set the action mode changing knob to the symbol. Position the drill bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole. 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 and normal drilling may be resumed.

NOTE: Eccentricity in the drill bit rotation may occur while operating the tool with no load. The tool auto-matically centers itself during operation. This does not affect the drilling precision.

Chipping/Scaling/Demolition
