General Power Tool Safety Warnings
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and instruc-
tions may result in electric shock, re and/or serious
injury.
Save all warnings and instruc-
tions for future reference.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical safety
4. 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. Unmodied plugs and matching outlets will
reduce risk of electric shock.
5. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
6. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
7. 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.
8. 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.

5ENGLISH
9. If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
10. Use of power supply via a RCD with a rated
residual current of 30 mA or less is always
recommended.
Personal safety
11. 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 inuence of drugs, alcohol or med-
ication. A moment of inattention while operating
power tools may result in serious personal injury.
12. Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
13. Prevent unintentional starting. Ensure the
switch is in the o󰀨-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your nger on the switch or energising power tools
that have the switch on invites accidents.
14. 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.
15. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
16. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
17. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
Power tool use and care
18. 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.
19. Do not use the power tool if the switch does
not turn it on and o󰀨. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
20. Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.
21. Store idle power tools out of the reach of chil-
dren 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.
22. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may a󰀨ect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
23. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
24. Use the power tool, accessories and tool bits
etc. in accordance with these instructions, tak-
ing into account the working conditions and
the work to be performed. Use of the power tool
for operations di󰀨erent from those intended could
result in a hazardous situation.
Service
25. Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
26. Follow instruction for lubricating and chang-
ing accessories.
27. Keep handles dry, clean and free from oil and
grease.
GRINDER SAFETY WARNINGS
Safety Warnings Common for Grinding, Sanding,
Wire Brushing, or Abrasive Cutting-O󰀨 Operations:
1. This power tool is intended to function as a
grinder, sander, wire brush or cut-o󰀨 tool.
Read all safety warnings, instructions, illus-
trations and specications provided with this
power tool. Failure to follow all instructions listed
below may result in electric shock, re and/or
serious injury.
2. Operations such as polishing are not rec-
ommended to be performed with this power
tool. Operations for which the power tool was not
designed may create a hazard and cause per-
sonal injury.
3. Do not use accessories which are not speci-
cally designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
4. The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than
their rated speed can break and y apart.
5. The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
6. Threaded mounting of accessories must
match the grinder spindle thread. For acces-
sories mounted by anges, the arbour hole of
the accessory must t the locating diameter
of the ange. Accessories that do not match the
mounting hardware of the power tool will run out of
balance, vibrate excessively and may cause loss
of control.

6ENGLISH
7. Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or acces-
sory is dropped, inspect for damage or install
an undamaged accessory. After inspecting and
installing an accessory, position yourself and
bystanders away from the plane of the rotating
accessory and run the power tool at maximum
no-load speed for one minute. Damaged acces-
sories will normally break apart during this test
time.
8. Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments.
The eye protection must be capable of stopping
ying debris generated by various operations.
The dust mask or respirator must be capable of
ltrating particles generated by your operation.
Prolonged exposure to high intensity noise may
cause hearing loss.
9. Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken accessory
may y away and cause injury beyond immediate
area of operation.
10. Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hid-
den wiring or its own cord. Cutting accessory
contacting a “live” wire may make exposed metal
parts of the power tool “live” and could give the
operator an electric shock.
11. Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
12. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
13. Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
14. Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
15. Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
16. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolled power tool to be forced in the direction opposite
of the accessory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel that is
entering into the pinch point can dig into the surface of
the material causing the wheel to climb out or kick out.
The wheel may either jump toward or away from the
operator, depending on direction of the wheel’s move-
ment at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a) Maintain a rm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or kick-
back forces, if proper precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) Do not position your body in the area where
power tool will move if kickback occurs.
Kickback will propel the tool in direction opposite
to the wheel’s movement at the point of snagging.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and snagging
the accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
e) Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades create
frequent kickback and loss of control.
Safety Warnings Specic for Grinding and Abrasive
Cutting-O󰀨 Operations:
a) Use only wheel types that are recommended
for your power tool and the specic guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
b) The grinding surface of centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot
be adequately protected.
c) The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed
towards the operator. The guard helps to protect
the operator from broken wheel fragments, acci-
dental contact with wheel and sparks that could
ignite clothing.
d) Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-o󰀨 wheel. Abrasive cut-o󰀨 wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to
shatter.

7ENGLISH
e) Always use undamaged wheel anges that
are of correct size and shape for your selected
wheel. Proper wheel anges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-o󰀨 wheels may be di󰀨erent from
grinding wheel anges.
f) Do not use worn down wheels from larger
power tools. Wheel intended for larger power tool
is not suitable for the higher speed of a smaller
tool and may burst.
Additional Safety Warnings Specic for Abrasive
Cutting-O󰀨 Operations:
a) Do not “jam” the cut-o󰀨 wheel or apply
excessive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twisting
or binding of the wheel in the cut and the possibil-
ity of kickback or wheel breakage.
b) Do not position your body in line with and
behind the rotating wheel. When the wheel, at
the point of operation, is moving away from your
body, the possible kickback may propel the spin-
ning wheel and the power tool directly at you.
c) When wheel is binding or when interrupting
a cut for any reason, switch o󰀨 the power
tool and hold the power tool motionless until
the wheel comes to a complete stop. Never
attempt to remove the cut-o󰀨 wheel from the
cut while the wheel is in motion otherwise
kickback may occur. Investigate and take correc-
tive action to eliminate the cause of wheel binding.
d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
e) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the
edge of the workpiece on both sides of the wheel.
f) Use extra caution when making a “pocket
cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can cause
kickback.
Safety Warnings Specic for Sanding Operations:
a) Do not use excessively oversized sanding
disc paper. Follow manufacturers recommen-
dations, when selecting sanding paper. Larger
sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
Safety Warnings Specic for Wire Brushing
Operations:
a) Be aware that wire bristles are thrown by
the brush even during ordinary operation. Do
not overstress the wires by applying excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
b) If the use of a guard is recommended for
wire brushing, do not allow any interference
of the wire wheel or brush with the guard. Wire
wheel or brush may expand in diameter due to
work load and centrifugal forces.
Additional Safety Warnings:
17. When using depressed centre grinding wheels,
be sure to use only berglass-reinforced
wheels.
18. NEVER USE Stone Cup type wheels with this
grinder. This grinder is not designed for these
types of wheels and the use of such a product
may result in serious personal injury.
19. Be careful not to damage the spindle, the
ange (especially the installing surface) or the
lock nut. Damage to these parts could result in
wheel breakage.
20. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
21. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
22. Use the specied surface of the wheel to per-
form the grinding.
23. Do not leave the tool running. Operate the tool
only when hand-held.
24. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
25. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
26. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
27. Use only anges specied for this tool.
28. For tools intended to be tted with threaded
hole wheel, ensure that the thread in the wheel
is long enough to accept the spindle length.
29. Check that the workpiece is properly
supported.
30. Pay attention that the wheel continues to
rotate after the tool is switched o󰀨.
31. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure opera-
tor safety.
32. Do not use the tool on any materials contain-
ing asbestos.
33. When use cut-o󰀨 wheel, always work with
the dust collecting wheel guard required by
domestic regulation.
34. Cutting discs must not be subjected to any
lateral pressure.
35. Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.

OPERATION
WARNING:
• It should never be necessary to force the tool.
The weight of the tool applies adequate pres-
sure. Forcing and excessive pressure could
cause dangerous wheel breakage.
• ALWAYS replace wheel if tool is dropped while
grinding.
• NEVER bang or hit grinding disc or wheel onto
work.
• Avoid bouncing and snagging the wheel, espe-
cially when working corners, sharp edges etc.
This can cause loss of control and kickback.
• NEVER use tool with wood cutting blades and
other sawblades. Such blades when used on a
grinder frequently kick and cause loss of control
leading to personal injury.
CAUTION:
• After operation, always switch o󰀨 the tool and
wait until the wheel has come to a complete stop
before putting the tool down.
Grinding and sanding operation
► Fig.11

WARNING:
• When using an abrasive cut-o󰀨 / diamond
wheel, be sure to use only the special wheel
guard designed for use with cut-o󰀨 wheels.
• NEVER use cut-o󰀨 wheel for side grinding.
• Do not “jam” the wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or
binding of the wheel in the cut and the possibility
of kickback, wheel breakage and overheating of
the motor may occur.
• Do not start the cutting operation in the work-
piece. Let the wheel reach full speed and care-
fully enter into the cut moving the tool forward
over the workpiece surface. The wheel may
bind, walk up or kickback if the power tool is
started in the workpiece.
• During cutting operations, never change the
angle of the wheel. Placing side pressure on
the cut-o󰀨 wheel (as in grinding) will cause the
wheel to crack and break, causing serious per-
sonal injury.
• A diamond wheel shall be operated perpendicu-
lar to the material being cut.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched o󰀨 and
unplugged before attempting to perform inspec-
tion or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
The tool and its air vents have to be kept clean.
Regularly clean the tool's air vents or whenever the
vents start to become obstructed.
► Fig.13: 1. Exhaust vent 2. Inhalation vent
Replacing carbon brushes
► Fig.14: 1. Limit mark
Remove and check the carbon brushes regularly.

其他冷却液可能会导致触电或死亡。
反弹和相关警告
反弹是正在旋转的砂轮、垫片、钢丝刷或其
他配件卡滞或卡滞时突然产生的反作用力。
卡滞会导致旋转配件的快速停止，从而导致
在卡滞点处对失控的工具产生与配件旋转方
向相反的作用力。
例如，如果工件使得砂轮卡滞，则进入卡滞
点的砂轮边缘将进入工件材料的表面，导致
砂轮跳出或弹出。根据砂轮在卡滞点的运动
方向，砂轮可能会跳向或远离操作者。在这
种情况下，砂轮也可能会破裂。
电动工具误操作和／或不正确的操作步骤或
操作条件将导致反弹，遵守以下所述的注意
事项即可避免。
a) 请牢固持握电动工具的把手，调整身
体和手臂位置以防止反弹力。如果提供
了辅助手柄，请务必使用，以在启动时
最大程度地控制反弹或转矩反作用力。
如果正确遵守注意事项，操作者可控制
转矩反作用力或反弹力。
b) 切勿将手靠近旋转的附件。附件可能
会反弹到您手上。
c) 请勿置身于发生反弹时电动工具可能
移动的区域内。反弹会在卡滞点处以与
砂轮运动方向相反的力作用于砂轮。
d) 当处理边角、锐利的边缘等处时请特
别小心。避免使附件跳跃和卡滞。边角、
锐利的边缘或附件发生跳跃可能会使旋转
的附件被钩住并导致工具失控或反弹。
e) 请勿安装锯链木雕锯片或齿状锯片。
这些锯片会发生频繁的反弹并导致工具
失控。
专用于磨削和砂轮切割操作的安全警告：
a) 请仅使用被推荐用于您的电动工具的
砂轮以及专用于所选砂轮的砂轮罩。非
专用于本电动工具的砂轮无法得到足够
的防护并无法保证安全。
b) 钹形砂轮的砂磨表面必须安装在砂轮
罩边缘的平面之下。突出于砂轮罩边缘
平面的安装不当的砂轮将不能得到充分
的保护。
c) 砂轮罩必须牢固安装到电动工具上并
放置在最为安全的位置，使得砂轮外露
的部分尽可能地少。砂轮罩可防止操作
者被砂轮碎片划伤或意外接触到砂轮和
可能会点燃衣物的火星。
d) 仅可将砂轮用于推荐的应用情况。例
如：请勿用切割砂轮的侧面进行磨削。
切割砂轮用于进行外围磨削，对这些砂
轮应用侧力可能会导致其破碎。

15
中文简体
e) 请务必使用未损坏的砂轮法兰，尺寸
和外形应符合您所选的砂轮。正确的砂
轮法兰可减少砂轮破裂的危险。切割砂
轮的法兰可能与磨削砂轮法兰有所不同。
f) 请勿使用从更大的电动工具上拆下来
的已磨损的砂轮。用于大型电动工具的
砂轮不适合小型工具的高速操作，可能
会爆裂。
专用于砂轮切割操作的附加安全警告：
a) 请勿“挤压”切割砂轮或对其过度施
压。请勿试图切割过深。对砂轮过度施
压会使负荷增加，使砂轮在切割时易于
扭曲或卡滞，也使发生反弹或砂轮破裂
的可能性增大。
b) 请勿与旋转的砂轮成一直线站立或站
在其后面。如果操作时砂轮的移动方向
为远离您，如果此时发生反弹，则可能
会迫使旋转的砂轮直接指向您。
c) 当砂轮卡滞或因任何原因中断切割操
作时，请关闭电动工具并将工具保持不
动，直至砂轮完全停止。当砂轮还在运
动中时，切勿试图将切割砂轮从工件中
取出，否则可能会造成反弹。研究并采
取正确的措施以避免砂轮卡滞
d) 请勿在工件中重新启动切割操作。
请等到砂轮到达全速后再小心地重新进
行切割。如果电动工具在工件中重新启
动，则砂轮可能会卡滞、移动或反弹。
e) 请支撑面板或其他大型工件以最大限
度地降低砂轮卡滞和反弹的可能。大型
工件会因自身的重量而下陷。必须在工
件下面靠近切割线和砂轮两侧工件边缘
放置支撑件。
f) 当在墙壁或其他盲区进行“袖珍切割”
时请尤其小心。凸出的砂轮可能会切割
到气管或水管、电线或其他物体，从而
导致反弹。
专用于砂磨操作的安全警告：
a) 请勿使用尺寸过大的砂纸。选择砂纸
时请遵照制造商的推荐。大于砂盘的砂
纸会有破裂的危险并可能导致砂轮片的
卡滞、破裂或反弹。
专用于钢丝刷操作的安全警告：
a) 即使在正常操作时也请小心钢丝刷的
钢毛飞出。请勿使钢丝刷过载导致钢丝
过压。钢毛很容易穿透轻薄的衣服和／
或皮肤。
b) 如果建议为钢丝刷配备护罩，请勿使
其影响到钢丝轮或在带有护罩的情况下
使用钢丝刷。根据工作负荷和离心力作
用，钢丝轮或钢丝刷在直径上可能会有
所伸展。
附加安全警告：
17. 当使用钹形砂轮时，请务必且仅可使用
玻璃钢砂轮。
18. 使用本磨光机时切勿使用机碗形砂轮。
此类砂轮不适用于本磨光机，强行使用
可能会导致严重的人身伤害。
19. 请小心勿损坏主轴、法兰（尤其是安装
表面）或锁紧螺母。这些部件损坏可能
会导致砂轮破裂。
20. 打开开关前，请确认砂轮未与工件接触。
21. 在实际的工件上使用工具之前，请先让
工具空转片刻。请注意，振动或摇摆可
能表示安装不当或砂轮不平衡。
22. 请使用砂轮的指定表面来执行磨削。
23. 运行中的工具不可离手放置。只可在手
握工具的情况下操作工具。
24. 操作之后，请勿立刻触摸工件，因为其

Simbol
Berikut akan ditunjukkan simbol yang digunakan untuk
peralatan. Pastikan Anda memahami arti masing-
masing simbol sebelum menggunakan alat.
Baca petunjuk penggunaan.
ISOLASI GANDA
Gunakan kaca mata pengaman.
Hanya untuk negara UE
Jangan membuang peralatan listrik
bersama material limbah rumah tangga!
Dengan memerhatikan Petunjuk Eropa
tentang Limbah Peralatan Listrik dan
Elektronik serta pelaksanaannya sesuai
dengan ketentuan hukum nasional,
peralatan listrik yang telah habis masa
pakainya harus dikumpulkan secara
terpisah dan dikembalikan ke fasilitas daur
ulang yang kompatibel dengan lingkungan.
Penggunaan
Mesin ini dirancang untuk menggerinda, mengampelas
dan memotong logam dan material batuan tanpa
menggunakan air.
Pasokan daya
Mesin harus terhubung dengan pasokan daya listrik
yang bervoltase sama dengan yang tertera pada pelat
nama, dan hanya dapat dijalankan dengan listrik AC
fase tunggal. Mesin diisolasi ganda sehingga dapat
juga dihubungkan dengan soket tanpa kabel arde.
Peringatan Keselamatan Umum
Mesin Listrik
PERINGATAN Bacalah semua peringatan
keselamatan dan semua petunjuk. Kelalaian
mematuhi peringatan dan petunjuk dapat menyebabkan
sengatan listrik, kebakaran dan/atau cedera serius.
Simpanlah semua peringatan
dan petunjuk untuk acuan di
masa depan.
Istilah “mesin listrik” dalam semua peringatan mengacu
pada mesin listrik yang dijalankan dengan sumber listrik
jala-jala (berkabel) atau baterai (tanpa kabel).
Keselamatan tempat kerja
1. Jaga tempat kerja selalu bersih dan
berpenerangan cukup. Tempat kerja yang
berantakan dan gelap mengundang kecelakaan.
2. Jangan gunakan mesin listrik dalam
lingkungan yang mudah meledak, misalnya
terdapat cairan, gas, atau debu yang mudah
terbakar. Mesin listrik menimbulkan bunga api
yang dapat membakar debu atau uap tersebut.
3. Jauhkan anak-anak dan orang lain saat
menggunakan mesin listrik. Jika perhatian
terpecah, Anda mungkin saja kehilangan kendali.
Keamanan Kelistrikan
4. Steker mesin listrik harus cocok dengan
stopkontak. Jangan sekali-kali mengubah
steker dengan cara apa pun. Jangan
menggunakan steker adaptor dengan mesin
listrik yang terbumi (dibumikan). Steker yang
tidak diubah dan stopkontak yang cocok akan
mengurangi risiko sengatan listrik.
5. Hindari sentuhan tubuh dengan permukaan
yang terbumi atau dibumikan seperti pipa,
radiator, kompor, dan kulkas. Risiko sengatan
listrik bertambah jika ada bagian tubuh Anda yang
menyentuh bumi atau tanah.
