NOTE

The recharging time may vary according to the ambient

temperature and power source voltage.

CAUTION

When the battery charger has been continuously used,

the battery charger will be heated, thus constituting

the cause of the failures. Once the charging has been

completed, give 15 minutes rest until the next charging.

4. Disconnect the charger’s power cord from the

receptacle.

5. Hold the charger ﬁ rmly and pull out the battery.

NOTE

Be sure to pull out the battery from the charger after use,

and then keep it.

Regarding electric discharge in case of new batteries,

etc.

As the internal chemical substance of new batteries and

batteries that have not been used for an extended period

is not activated, the electric discharge might be low when

using them the ﬁ rst and second time. This is a temporary

phenomenon, and normal time required for recharging

will be restored by recharging the batteries 2 – 3 times.

How to make the batteries perform longer.

(1) Recharge the batteries before they become completely

exhausted.

When you feel that the power of the tool becomes

weaker, stop using the tool and recharge its battery.

If you continue to use the tool and exhaust the electric

current, the battery may be damaged and its life will

become shorter.

(2) Avoid recharging at high temperatures.

A rechargeable battery will be hot immediately after

use. If such a battery is recharged immediately after

use, its internal chemical substance will deteriorate, and

the battery life will be shortened. Leave the battery and

recharge it after it has cooled for a while.

CAUTION

○ If the battery is charged while it is heated because it has

been left for a long time in a location subject to direct

sunlight or because the battery has just been used,

the pilot lamp of the charger lights up green or lights

for 1 second, does not light for 0.5 seconds (oﬀ for 0.5

seconds). In such a case, ﬁ rst let the battery cool, then

start charging.

○ When the pilot lamp ﬂ ickers in red (at 0.2-seconds

intervals), check for and take out any foreign objects in

the charger’s battery connector. If there are no foreign

objects, it is probable that the battery or charger is

malfunctioning. Take it to your authorized Service Center.

13

English

○ Since the built-in micro computer takes about 3 seconds

to conﬁ rm that the battery being charged with chargers

are taken out, wait for a minimum of 3 seconds before

reinserting it to continue charging. If the battery is

reinserted within 3 seconds, the battery may not be

properly charged.

SELECT OPERATION MODE

Pressing the changeover switch allows the selection of

rotation speed and the auto stop function.

○ Rotation speed (Low mode/Normal mode) (Fig. 18)

Select either Low mode or Normal mode and operate the

tool in the selected speed.

○ Auto stop mode (on/oﬀ ) (Fig. 19)

This product is equipped with an auto stop function to

support continuous drilling work. The function features a

memory mode for storing the work time for drilling from

switch ON to switch OFF, and an auto stop mode that

automatically stops the motor from the second drilling

onward should the work exceed the stored work time

while the switch is ON.

AUTO STOP FUNCTION

In selection mode, pressing the button for longer than two

seconds will move to memory mode. (Fig. 19)

(At the same time the auto stop lamp will blink.)

Conduct drilling when the auto stop lamp is ﬂ ashing. The

time between switching ON and switching OFF is stored by

the tool.

(At the same time, the auto stop lamp will light up.)

Conduct drilling when the auto stop lamp is ﬂ ashing.

Continuous drilling is possible as the memory storage time

will be recorded by the tool until the auto stop function’s auto

stop mode is cancelled.

The auto stop function is cancelled by pressing the

changeover switch once again for over two seconds.

(At the same time, the auto stop lamp will switch oﬀ .)

CAUTION

○ Switch ON the tool once you place the tip of the tool on

the work material.

○ The rotation speed and the level at which the switch is

pulled during drilling is not stored to memory.

○ Fully carry out drilling in one go during auto stop mode.

○ The motor will stop even if you switch OFF within the

memory storage time.

○ When you switch OFF within the memory storage time,

the count will be reset. If you rework a task in which a

hole has been partially drilled, the memory storage time

will be fully recounted.

○ The auto stop function will remain active until canceled.

REACTIVE FORCE CONTROL

This product is equipped with a Reactive Force Control

(RFC) feature that reduces jerking of the tool body.

If the tool bit is suddenly overburdened, any jerking of the

tool body is reduced by activation of the slip clutch or by

stopping of the motor by the sensor built into the tool body.

If the motor is stopped because of overburdening detection

by the controller, the display lamp will blink while the switch

is pulled. In addition, the lamp will continue blinking for

approximately three seconds after the switch is released.

The motor will remain stopped while the lamp is blinking.

(Fig. 23)

Because the RFC feature may not activate or its performance

may be insuﬃ cient depending on the working environment

and conditions, be careful not to suddenly overburden the

Allow the unit to cool

for 15 to 30 minutes.

When the temperature

goes down and the

display lamp blinking

stops, pull the switch

trigger to recover

operation.

Sudden

overburdening of

the tool bit has

activated the RFC,

stopping further

operation of the

tool.

RFC (See page 13

“REACTIVE FORCE

CONTROL”)

Release the switch

trigger and leave it

until the display lamp

blinking stops. Pull the

switch trigger again to

recover operation.

Before continuing

operation, remove

the cause of the

overburden.

NOTE

Despite taking steps to correct a problem, the display

lamp may continue to blink. Should this be the case, the

unit may require repair. If so, please contact the outlet

from which this product was purchased for repairs.

LUBRICATION

This Rotary Hammer is of full air-tight construction to protect

against dust.

Therefore, this Rotary Hammer can be used without

lubrication for long periods.

After purchase, periodically replace grease. Ask for grease

replacement at the nearest authorized Service Center.

CAUTION

A speciﬁ c grease is used with this machine, therefore,

the normal performance of the machine may be badly

aﬀ ected by use of diﬀ erent grease. Please be sure to let

one of our service centers to undertake replacement of

the grease.

MAINTENANCE AND INSPECTION

WARNING

Be sure to turned oﬀ the switch and remove the battery

before maintenance and inspection.

1. Inspecting the tool

Since use of as dull tool will degrade eﬃ ciency and

cause possible motor malfunction, sharpen or replace

the tool as soon as abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that

they are properly tightened. Should any of the screws be

loose, retighten them immediately. Failure to do so could

result in serious hazard.

3. Maintenance of the motor

The motor unit winding is the very “heart” of the power

tool. Exercise due care to ensure the winding does not

become damaged and/or wet with oil or water.

4. Inspection of terminals (tool and battery)

Check to make sure that swarf and dust have not

collected on the terminals.

On occasion check prior, during and after operation.

CAUTION

Remove any swarf or dust which may have collected on

the terminals.

Failure to do so may result in malfunction.

5. Cleaning on the outside

When the power tool is stained, wipe with a soft dry cloth

or a cloth moistened with soapy water. Do not use chloric

solvents, gasoline or paint thinner, for they melt plastics.

6. Cleaning the battery installation compartment and

the battery

After drilling concrete, if concrete dust has accumulated

on the battery installation compartment and the battery,

clean oﬀ the accumulated concrete dust with an air gun

or a dry cloth before using the tool. (Fig. 21)

Also, after cleaning, ensure that the battery can be

installed and removed smoothly from the tool.

CAUTION

Using the tool when the battery is covered with concrete

dust may lead to accidents such as the battery falling

during use.

Furthermore, such use may cause a malfunction or

contact failure between the battery and the terminals.

7. Storage

Store the power tool and battery in a place in which

the temperature is less than 40°C and out of reach of

children.

NOTE

Storing lithium-ion batteries.

Make sure the lithium-ion batteries have been fully

charged before storing them.

Prolonged storage (3 months or more) of batteries with

a low charge may result in performance deterioration,

signiﬁ cantly reducing battery usage time or rendering

the batteries incapable of holding a charge.

However, signiﬁ cantly reduced battery usage time may

be recovered by repeatedly charging and using the

batteries two to ﬁ ve times.

If the battery usage time is extremely short despite

repeated charging and use, consider the batteries dead

and purchase new batteries.

CAUTION

In the operation and maintenance of power tools, the

safety regulations and standards prescribed in each

country must be observed.
