䡬利用 ROTATION（旋鑽）動作︰

在金屬﹑木材和塑料上鑽孔-

作業之前

1. 電源

確認所使用的電源與產品名牌上標示的規格是否

相符-

2. 電源開關

確認電源開關是否切斷-若電源開關接通﹐則插

頭插入電源插座時電動工具將出其不意地立刻轉

動﹐從而招致嚴重事故-

3. 延伸線纜

若作業場所移到離開電源的地點﹐應使用容量足

夠﹑鎧裝合適的延伸線纜﹐並且要盡可能地短些-

4. 鑽頭的裝配和拆卸

對于帶夾盤扳手的鑽頭夾盤（圖 1）

將鑽頭插人夾盤並用夾盤扳手固定之﹐通過轉動

三個孔口固定夾盤-

選購附件可能不預先通告而徑予更改-

用途

䡬利用 ROTATION（旋鑽）和 IMPACT（沖擊）的

組合動作︰

在堅硬材料（混凝土﹑大理石﹑花崗岩﹑瓷磚

等）上鑽孔-

使用沖擊電鑽時應注意事項

1. 使用沖擊電鑽時要戴好耳罩-

暴露在噪聲中會引起聽力損傷-

2. 使用隨工具提供的輔助手柄-

操作失手會引起人身傷害-

3. 在鑽入牆壁﹑天花板或地板之前﹐務必確認其中

沒有埋設電纜-

4. 當在 IMPACT（沖擊）模式下鑽混凝土或類似的

堅硬材料時﹐請將鑽頭旋鑽開關杆設到 R（右）

側-（圖 8）

5. 請勿擰緊螺絲及螺帽﹑螺母等-擰緊后旋轉部分

會突然停止﹐不但機器會發生故障﹐還會使人受

傷-

08.9.11, 11:01Page 4

對于無鍵夾盤（圖 2﹑3）

(1) 裝配鑽頭

沿“AUF. RELEASE” 方向轉動鎖緊軸環並打開夾

盤-將鑽頭盡可能插人夾盤之後﹐沿“GRIP. ZU”

方向轉動鎖緊軸環-夾緊扣環並通過順時針（前

視）轉動套管關閉夾盤-

(2) 拆卸鑽頭

沿“AUF. RELEASE”方向轉動鎖緊軸環以解除剝

離力-夾緊扣環並通過逆時針轉動套管關閉夾盤-

注

如果擰不松套管﹐請將一普通扳手固定到軸上﹐握

緊普通扳手﹐然后用手轉動套管將其擰松- （圖

4）

5. 選擇合適的鑽頭

䡬混凝土或石材…請使用“選購附件”一節中規定

的鑽頭-

䡬金屬或塑料…使用通常的金屬用鑽頭-

䡬木材鑽孔：使用通常的木工用鑽頭-

但鑽開直經 6.5 毫米或更小的孔口時﹐宜使用金屬

用鑽頭-

6. 確認鑽頭旋轉方向（圖 5）

按換向開關控製杆的 R（右）側時﹐鑽頭順時針

（從后面看）轉動-而按該控製杆的 L（左）側

時﹐鑽頭逆時針（從后面看）轉動-

注意

○ 絕不能在鑽頭旋轉期間改變其轉動方向-

在改變鑽頭轉動方向之前﹐要把電源開關打到

關位置-否則﹐馬達會燒掉-

○ 當把它作為衝擊式電鑽時﹐總是在順時針方向

使用-

7. 邊柄的裝配

先將邊柄插在連接部-

然後﹐按順時鐘方向旋轉邊柄扣﹐將邊柄固定住-

請將邊柄設在適合於操作的位置﹐然後旋緊邊柄

扣-

8. 衝擊式到旋轉式的轉換（圖 6）

只要簡單地滑動轉換手柄﹐就能把衝擊式電鑽從

衝擊式（衝擊加旋轉）轉換為旋轉式（只旋

轉）-當鑽水泥﹑石頭﹑磚瓦或類似的板材時﹐

將轉換手柄向右滑-鑽頭在旋轉的同時對所鑽的

材料進行衝擊-當鑽金屬﹑木頭或塑膠時﹐把轉

換手柄滑到最左端-此鑽便象通常電鑽一樣只是

旋轉-

注意

若被鑽的材料用平常的只旋轉的方式就能鑽﹐就不

要用衝擊方式- 因為這種功能不僅會降低鑽的效

率﹐而且容易損壞鑽頭-

當轉換時﹐要保証將轉換手柄滑到頭-

9. 高速／低速的轉換

要改變速度﹐如圖 7 中箭頭所示轉動換檔控製杆-

刻在鑽機上的數碼“1”表示低速﹐數碼“2”表

示高速-

實際操作步驟

1. 速度調節和開關操作

䡬通過控製起動器的壓力﹐可以將鑽機的速度從 0 調

至最大- 對起動器的壓力越大﹐鑽機便鑽得越

快-當起動器被完全壓下時﹐轉速最大-

䡬拉起動器開關並推製動器﹐保持開關合上狀態﹐

便于連續運轉-當開關斷開時﹐通過再次拉起動

器﹐製動器便可釋放-

注意

在木材上開孔時﹐請用全速度開孔-

2. 作為電鑽或沖擊電鑽使用時

(1) 鑽機的壓力

即使您用必要以上的強力按壓鑽機﹐也不能加快

鑽孔速度- 這樣不僅損傷鑽頭尖﹐降低工作效

率﹐還會縮短鑽頭尖的使用壽命-

(2) 穿孔時

當被鑽的物體被鑽穿時﹐鑽頭可能被損壞-在穿

孔之前一定要降低壓力-

注意

在連續運轉中﹐完成鑽孔工作后﹐還會進行 5 秒鐘

無負荷運轉-

(3) 使用粗鑽頭時

使用粗鑽頭時您的手臂會承受更大反作用力-小

心不要被反作用力推得移動位置-為此﹐請找好

立腳點﹐用雙手握緊鑽機﹐垂直對被鑽物體-

3. 使用大口徑鑽頭

鑽頭口徑越大﹐手上受到的反力也越大﹐因而必

需注意會不會因反力過大而失去控制-

為了獲得良好的控制﹐腳步要站穩﹐並用雙手牢

靠地握住鑽機- 同時﹐鑽頭與被鑽面要保持垂

直-

08.9.11, 11:01Page 5

4. 進行穿孔作業時

穿孔作業時﹐常因操作不慎使鑽機突然移動而損

壞鑽頭或鑽機主體-因此﹐必需提高警覺準備隨

時放鬆推力-

維護和檢查

1. 檢查鑽頭

繼續使用已磨損或損傷的鑽頭﹐不僅使工作效率

大為降低﹐同時又會導致電動機過載-因此﹐鑽

頭必須時常檢查﹐並根據情況需要換新件-

2. 檢查安裝螺釘

要經常檢查安裝螺釘是否緊固妥善-若發現螺釘鬆

了﹐應立即重新扭緊﹐否則會導致嚴重的事故-

3. 電動機的維護

電動機繞線是電動工具的心臟部-應仔細檢查有

無損傷﹐是否被油液或水沾濕-

4. 維修

電動工具一旦發生任何異常﹐應毫不遲疑地商詢

服務中心-

GENERAL SAFETY RULES

WARNING!

Read all instructions

Failure to follow all instructions listed below may result in

electric shock, fire and/or serious injury.

The term “power tool” in all of the warnings listed below

refers to your mains operated (corded) power tool or battery

operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

1) Work area

a) Keep work area clean and well lit.

Cluttered and dark areas invite accidents.

b) Do not operate power tools in explosive

atmospheres, such as in the presence of flammable

liquids, gases or dust.

Power tools create sparks which may ignite the

dust of fumes.

c) Keep children and bystanders away while operating

a power tool.

Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet.

Never modify the plug in any way.

Do not use any adapter plugs with earthed

(grounded) power tools.

Unmodified plugs and matching outlets will reduce

risk of electric shock.

b) Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and

refrigerators.

There is an increased risk of electric shock if your

body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk

of electric shock.

d) Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges or

moving parts.

Damaged or entangled cords increase the risk

of electric shock.

e) When operating a power tool outdoors, use an

extension cord suitable for outdoor use.

Use of a cord suitable for outdoor use reduces

the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use

common sense when operating a power tool.

Do not use a power tool while you are tired or

under the influence of drugs, alcohol or medication.

A moment of inattention while operating power

tools may result in serious personal injury.

b) Use safety equipment. Always wear eye protection.

Safety equipment such as dust mask, non-skid safety

shoes, hard hat, or hearing protection used for

appropriate conditions will reduce personal injuries.

c) Avoid accidental starting. Ensure the switch is in

the off position before plugging in.

Carrying power tools with your finger on the

switch or plugging in power tools that have the

switch on invites accidents.

d) Remove any adjusting key or wrench before

turning the power tool on.

A wrench or a key left attached to a rotating part

of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance

at all times.

This enables better control of the power tool in

unexpected situations.

f) Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing and gloves

away from moving parts.

Loose clothes, jewellery or long hair can be caught

in moving parts.

g) If devices are provided for the connection of dust

extraction and collection facilities, ensure these

are connected and properly used.

Use of these devices can reduce dust related

hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct

power tool for your application.

The correct power tool will do the job better and

safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not

turn it on and off.

Any power tool that cannot be controlled with the

switch is dangerous and must be repaired.

c) Disconnect the plug from the power source before

making any adjustments, changing accessories, or

storing power tools.

Such preventive safety measures reduce the risk

of starting the power tool accidentally.

d) Store idle power tools out of the reach of children

and do not allow persons unfamiliar with the

power tool or these instructions to operate the

power tool.

Power tools are dangerous in the hands of

untrained users.

e) Maintain power tools. Check for misalignment or

binding of moving parts, breakage of parts and

any other condition that may affect the power

tools operation.

If damaged, have the power tool repaired before

use.

Many accidents are caused by poorly maintained

power tools.

f) Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp cutting

edges are less likely to bind and are easier to

control.

g) Use the power tool, accessories and tool bits etc.,

in accordance with these instructions and in the

manner intended for the particular type of power

tool, taking into account the working conditions

and the work to be performed.

Use of the power tool for operations different from

intended could result in a hazardous situation.

5) Service

a) Have your power tool serviced by a qualified

repair person using only identical replacement

parts.

This will ensure that the safety of the power tool

is maintained.

PRECAUTION

Keep children and infirm persons away.

When not in use, tools should be stored out of reach

of children and infirm persons.

Optional accessories are subject to change without notice.

APPLICATIONS

䡬 By combined actions of ROTATION and IMPACT:

Boring holes in hard materials (concrete, marble,

granite, tiles, etc.)

䡬 By ROTATIONAL action:

Boring holes in metal, wood and plastic.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms

to the power requirements specified on the product

nameplate.

2. Power switch

Ensure that the power switch is in the OFF position.

If the plug is connected to a receptacle while the

power switch is in the ON position, the power tool

will start operating immediately, inviting serious

accident.

3. Extension cord

When the work area is removed from the power

source. Use an extension cord of sufficient thickness

and rated capacity. The extension cord should be

kept as short as practicable.

SPECIFICATIONS

*Be sure to check the nameplate on product as it is subject to change by areas.

PRECAUTIONS ON USING IMPACT DRILL

1. Wear ear protectors with impact drills.

Exposure to noise can cause hearing loss.

2. Use auxilliary handles supplied with the tool.

Loss of control can cause personal injury.

3. Before drilling into walls, ceilings or floors, ensure

that there are no concealed power cables inside.

4. When boring concrete or similar hard materials in

IMPACT mode, set the bit rotation switch lever to

the R-side. (Fig. 8)

5. Avoid tightening work of screws, bolts, and nuts;

otherwise, rotating sections may be stopped all of

a sudden, resulting in the malfunction of the main

body and risk of injury.

CAUTION

䡬 Never change the direction of bit rotation during

operation.

Turn the power switch OFF before changing the

direction of bit rotation; otherwise, the motor will

burn.

䡬 Always use with clockwise rotation, when using it

as an impact drill.

7. Side handle attachment

Attach the side handle to the mounting part.

Rotate the side handle grip in a clockwise direction

to secure it.

Set the side handle to a position that is suited to

the operation and then securely tighten the side

handle grip.

8. IMPACT to ROTATION changeover (Fig. 6)

The impact drill can be switched from IMPACT

(impact plus rotation) to ROTATION (rotation only)

by simply sliding the change knob. When boring

concrete, stone, tile or similar board materials, slide

the change knob right. The drill head impacts against

the material while continuing to rotate.

When boring metal, wood or plastic, slide the change

knob fully to the left. The drill simply rotates as

an ordinary electric drill.

CAUTION

Do not use the impact dril in the IMPACT mode

if the material can be bored by rotation only. Such

action will not only reduce drill afficiency, but may

also damage the drill tip.

When changing over, ensure the change knob is

slide as far as it will go.

9. High-spped/Low-speed changeover

To change speed, rotate the gear shift lever as

indicated by the arrow in Fig. 7. The numeral “1”

engraved on the drill body denotes low speed, the

numeral “2” denotes high speed.

PRACTICAL HANDLING PROCEDURES

1. Speed adjustment and switch operation

䡬 The drill speed can be adjusted from 0 through full

speed by regulating the trigger-squeezing force.

The more the trigger is squeezed, the faster the drill

rotates. When the trigger is squeezed fully, the

speed is the maximum.

䡬 Pulling the trigger switch and pushing the stopper,

keeps the switched-on condition which is convenient

for continuous running. When switching off, the

stopper can be disconnected by pulling the trigger

again.

CAUTION

Drill at a maximum rotation speed when drilling

wooden materials.

2. When using as a Drill or an Impact Drill

(1) Pressing force of the drill

You cannot drill holes more quickly even if you

press the drill with a stronger force than necessary.

It not only damages tip of drill bit and decreases

the efficiency of operation, but also shortens the

life of the drill tip.

(2) In case of penetrating holes

Drill bits can be broken when the material being

drilled is penetrated. It is important to decrease

pressing force just before penetrating.

CAUTION

In continuous operation, conduct no-load operation

for five seconds after completing a drilling job.

(3) When a thick drill bit is used

Your arm is subjected to larger reaction force when

a thicker drill bit is used. Be careful not to be moved

by the reaction force. For this, establish a foothold,

hold the unit tightly with both hands perpendicularly

to the material being drilled.

3. Using a large diameter drill bit

The larger the drill bit diameter, the larger the

reactive force on your arm. Be careful not to lose

control of the drill because of this reactive force.

To maintain firm control, establish a good foothold,

hold the drill tightly with both hands, and ensure

that the drill is vertical to the material being drilled.

4. When drilling completely through the material

When the drill bit bores completely through the

material, careless handling often results in a bro-

ken, drill bit or damage to the drill body itself due

to the sudden movement of the drill. Always be

alert and ready to release pushing force when drilling

through the material.

MAINTENANCE AND INSPECTION

1. Inspecting the drill bit

Continued use of a worn and/or damaged drill bit

will result in reduced drilling efficiency and may

seriously overload the drill motor. Inspect the drill

bit frequently and replace it as necessary.

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. Servicing

Consult an authorized Service Center in the event

of power tool failure.
