注意:
长时间将冲击起子机应用于螺丝会造成螺丝拧
得过紧，且容易使螺丝折断。
用冲击起子机拧紧螺丝时，如果起子机与螺丝
有一定角度，则可能损坏螺丝头，正确的作用
力无法传送到螺丝。
拧紧时，使冲击起子机正好对准螺丝。
8. 拧紧和拧松螺栓
首先必须选择与螺栓或螺母相对应的六角扳手。
接下来，将套筒安装到铁钻上，用六角扳手咬住
要拧紧的螺母。与螺栓成直线地握住工具，按电
源开关冲击螺母几秒钟。
如果螺母松动地安装到螺栓上，螺栓可能随着螺
母转动，则说明未正确拧紧。在此情况下，停止
冲击螺母，用扳手按住螺母头后重新启动冲击，
或者手动拧紧螺栓和螺母，以防它们滑动。
操作上的注意事项
1. 连续作业后须让电动工具休息片刻
在连续进行螺栓紧固作业后以及在更换电池后，
请让电动工具暂停作业 15 分钟。如果在更换电
池后立刻开始作业，马达和开关等的温度将会升
高，结果导致烧毁。
注：
请勿触摸金属部件，它们在连续工作后可能高
温。
2. 关于转速控制开关的注意事项
此开关带有可无级改变转速的内置电路。因此，
当轻拉启动开关（低速转动）并在连续旋紧螺丝
中停止马达转动时，电路部分的元件可能会因过
热而损坏。
3. 使用适宜於螺丝的旋紧时间
根据螺丝的材料和尺寸以及所旋紧的材料等，其
适宜的转矩有所不同，因此请使用适宜于该螺丝
的旋紧时间。尤其是，如果对小于 M8 的螺丝使
用过长的旋紧时间，则螺丝有损坏的危险。因
此，请事先确认旋紧时间和旋紧转矩。
4. 以适于受冲击螺栓的旋紧扭矩进行操作
螺栓和螺母最适宜的旋紧扭矩因螺栓或螺母的材
料和尺寸而有所不同。对小螺栓使用过大的旋紧
扭矩会扭曲或损坏螺栓。旋紧扭矩的增加与操作
时间成正比。请使用正确的螺栓操作时间。
5. 握住工具
用双手牢牢握住工具。在这种情况下，与螺丝或
螺栓成直线地握住工具。
无需用力推工具，用足以抵消冲击力的力握住工
具。
6. 确定旋紧扭矩
下列因素会造成旋紧扭矩的下降。因此请在工作
前用手工扭矩扳手来确定上紧螺栓所需的实际旋
紧扭矩。影响旋紧扭矩的因素如下。
(1) 电压
达到放电极限时，电压降低，旋紧扭矩也减少。
(2) 操作时间
操作时间增加时旋紧扭矩也增加。但是，即使工
具驱动很长的一段时间，旋紧扭矩也不会增大到
超过某个特定值。
(3) 螺栓的直径
旋紧扭矩根据螺栓的直径变化。一般来说较大直
径的螺栓需要较大的旋紧扭矩。
(4) 旋紧的状态
即使使用相同尺寸螺纹的螺栓，旋紧扭矩根据螺
栓的扭矩比率、等级和长度也各不相同。旋紧扭
矩还因螺栓所要上紧的加工件的表面状况而有所
不同。螺栓和螺母一起转动时，扭矩会大大减
少。
(5) 拧紧扭矩因电池充电程度而异。
维 护 和 检 查
1. 检查工具
继续使用已破损的钻头或钻头尖已磨损的钻头是
非常危险的，因为钻头会滑脱。因此，请更换已
破损的钻头或钻头尖已磨损的钻头。
2. 检查安装螺钉
要经常检查安装螺钉是否紧固妥善。若发现螺钉
松了，应立即重新扭紧，否则会导致严重的事
故。
3. 电动机的维护
电动机绕线是电动工具的“心脏部”应仔细检查
有无损伤，是否被油液或水沾湿。
4. 清理外部
冲击起子机沾污时，用干软布或沾肥皂水的布擦
拭。切勿使用氯溶液、汽油或稀释剂，以免塑胶
部分溶化。
5. 收藏
冲击起子机应收藏于温度低于40℃和小孩拿不到
的地方。
注:
在电池长期存放（3 个月或更长）后务必给电
池完全充电。如果长期存放后使用，容量小的
电池可能无法充电。

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 offposition 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) Battery tool use and care
a) Ensure the switch is in the offposition before
inserting battery pack.
Inserting the battery pack into power tools that have
the switch on invites accidents.
b) Recharge only with the charger specified by the

NOTE:
The charging time may vary according to temperature
and power source voltage.
4. Disconnect the charger’s power cord from the
receptacle
5. Hold the charger firmly and pull out the battery
NOTE:
After charging, pull out batteries from the charger first,
and then keep the batteries properly.
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 first 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
○When the battery charger has been continuosly 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.
○If the battery is recharged when it is warm due to battery
use or exposure to sunlight, the pilot lamp map light in
green.
The battery will not be recharged. In such a case, let the
battery cool before charging.
○When the pilot lamp flickers in red (at 0.2-second
intervals), check for and take out any foreign objects
in the charger’s battery installation hole. If there are no
foreign objects, it is probable that the battery or charger
is malfunctioning. Take it to your authorized Service
Center.
PRIOR TO OPERATION
1. Preparing and checking the work environment
Make sure that the work site meets all the conditions laid
forth in the precautions.
2. Checking the battery
Make sure that the battery is installed firmly. If it is at all
loose it could come offand cause an accident.
3. Installing the bit
Always follow the following procedure to install driver bit.
(Fig. 5)
(1) Pull the guide sleeve away from front of the tool.
(2) Insert the bit into the hexagonal hole in the anvil.
(3) Release the guide sleeve and it returns to its original
position.
(4) If you want to remove the bit, pull the guide sleeve away
from front of the tool.
CAUTION
If the guide sleeve does not return to its original position,
then the bit is not installed properly.
HOW TO USE
1. Check the rotational direction
The bit rotates clockwise (viewed from the rear side) by
pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn the bit
counterclockwise (See Fig. 6) (The and marks are
provided on the body).
2. Switch operation
○When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
○The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly and
increases as the trigger switch is pulled more.
NOTE:
A buzzing noise is produced when the motor is about to
rotate. This is only a noise, not a machine failure.
3. Using the hook
The hook is used to hang up the power tool to your waist
belt while working.
CAUTION
○When using the hook, hang up the power tool firmly not to
drop accidentally.
If the power tool is dropped, it may lead to an accident.
○When carrying the power tool with hooked to your waist
belt, do not fit any bit to the tip of power tool. If the sharp
bit such as drill is fitted to the power tool when carrying it
with hooked to your waist belt, you will be injured.
○Install securely the hook. Unless the hook is securely
installed, it may cause an injury while using.
(1) Removing the hook.

7. Tightening and loosening screws
Install the bit that matches the screw, line up the bit in the
grooves of the head of the screw, then tighten it.
Push the impact driver just enough to keep the bit fitting
the head of the screw.
CAUTION
Applying the impact driver for too long tightens the screw
too much and can break it.
Tightening a screw with the impact driver at an angle to
that screw can damage the head of the screw and the
proper force will not be transmitted to the screw. Tighten
with this impact driver lined up straight with the screw.
8. Tightening and loosening bolts
A hex. socket matching the bolt or nut must first be
selected. Then mount the socket on the anvil, and grip
the nut to be tightened with the hex. socket. Holding the
tool in line with the bolt, press the power switch to impact
the nut for several seconds.
If the nut is only loosely fitted to the bolt, the bolt may turn
with the nut, therefore mistaking proper tightening. In this
case, stop impact on the nut and hold the bolt head with a
wrench before restarting impact, or manually tighten the
bolt and nut to prevent them slipping.
OPERATIONAL CAUTIONS
1. Resting the unit after continuous work
After use for continuous bolt-tightening work, rest the
unit for 15 minutes or so when replacing the battery. The
temperature of the motor, switch, etc., will rise if the work
is started again immediately after battery replacement,
eventually resulting in burnout.
NOTE:
Do not touch the metal parts, as it gets very hot during
continuous work.
2. Cautions on use of the speed control switch
This switch has a built-in, electronic circuit which
steplessly varies the rotation speed. Consequently,
when the switch trigger is pulled only slightly (low speed
rotation) and the motor is stopped while continuously
driving in screws, the components of the electronic circuit
parts may overheat and be damaged.

3. Use a tightening time suitable for the screw
The appropriate torque for a screw differs according to
the material and size of the screw, and the material being
screwed etc., so please use a tightening time suitable for
the screw. In particular, if a long tightening time is used in
the case of screws smaller than M8, there is a danger of
the screw breaking, so please confirm the tightening time
and the tightening torque beforehand.
4. Work at a tightening torque suitable for the bolt
under impact
The optimum tightening torque for nuts or bolts differs
with material and size of the nuts or bolts. An excessively
large tightening torque for a small bolt may stretch
or break the bolt. The tightening torque increases
in proportion to the operation time. Use the correct
operating time for the bolt.
5. Holding the tool
Hold the tool firmly with both hands. In this case hold the
tool in line with the screw or bolt.
It is not necessary to push the tool very hard. Hold the
tool with a force just sufficient to counteract the impact
force.
6. Confirm the tightening torque
The following factors contribute to a reduction of the
tightening torque. So confirm the actual tightening torque
needed by screwing up some bolts before the job with
a hand torque wrench. Factors affecting the tightening
torque are as follows.
(1) Voltage
When the discharge margin is reached, voltage
decreases and tightening torque is lowered.
(2) Operating time
The tightening torque increases when the operating time
increases. But the tightening torque does not increase
above a certain value even if the tool is driven for a long
time.
(3) Diameter of bolt
The tightening torque differs with the diameter of the bolt.
Generally a larger diameter bolt requires larger tightening
torque.
(4) Tightening conditions
The tightening torque differs according to the torque ratio;
class, and length of bolts even when bolts with the same
size threads are used. The tightening torque also differs
according to the condition of the surface of workpiece
through which the bolts are to be tightened. When the
bolt and nut turn together, torque is greatly reduced.
(5) Tightening torque varies, depending on the battery’s
charge level.
MAINTENANCE AND INSPECTION
1. Inspecting the driver bit
Using a broken bit or one with a worn out tip is dangerous
because the bit can slip. Replace it.
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 may
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. Cleaning of the outside
When the impact driver is stained, wipe with a soft dry
cloth or a cloth moistened with soapy water. Do not use
chloric solvents, gasoline or paint thinner, as they melt
plastics.
5. Storage
Store the impact driver in a place in which the temperature
is less than 40°C, and out of reach of children.
NOTE:
Make sure that the battery is fully charged when stored
for a long period (3 months or more). The battery with
smaller capacity may not be able to be charged when
used, if stored for a long period.
