眼防护罩必须挡住各种操作产生的飞屑。防尘面具或口罩必须能过滤操作产
生的颗粒。长期暴露在高强度噪声中会引起失聪。
i) 让旁观者与工作区域保持－安全距离。任何进入工作区域的人必须戴上防护
用品。
工件或破损附件的碎片可能会飞出并引起紧靠着操作区域的旁观者的伤害。
切割附件触及带电导线会使电动工具外露的金属零件带电，并使操作者触电。
j) 当在切割附件有可能切割到暗线或自身电线的场所进行操作时，只能通过绝
缘握持面来握住电动工具。
切割附件碰到一根带电导线可能会使电动工具的外露金属零件带电并使操作
者发生电击危险。
k) 使软线远离旋转的附件。
如果操作不当、软线可能被切断或缠绕，并使得你的手或手臂可能被卷入旋
转附件中。
l) 直到附件完全停止运动才放下电动工具。
旋转的附件可能会抓住表面并拉动电动工具而让你失去对工具的控制。
m) 当携带电动工具时不要开动它。
意外地触及旋转附件可能会缠绕你的衣服而使附件伤害身体。
n) 经常清理电动工具的通风口。
电动机风扇会将灰尘吸进机壳，过多的金属粉末沉积会导致电气危险。
o) 不要在易燃材料附件操作电动工具。
火星可能会点燃这些材料。
p) 不要使用需用冷却液的附件。

反弹和相关警告
反弹是因卡住或缠绕住的旋转砂轮、靠背垫、或其他附件而产生的突然反作用力。
卡住或缠绕会引起旋转附件的迅速堵转，随之使失控的电动工具在卡住点产生
与附件旋转方向相反的运动。
例如，如果砂轮被工件缠绕或卡住，伸入卡住点的砂轮边缘可能会进入材料表
面而引起砂轮爬出或反弹。砂轮可能飞向或飞离操作者，这取决于砂轮在卡住
点的运动方向。在此条件下砂轮也可能碎裂。
反弹是电动工具误用和 / 或不正确操作工序或条件的结果，可以通过采取以下
给出的适当预防措施得以避免。
a) 保持紧握电动工具，使你的身体和手臂处于正确状态以抵抗反弹力。如有辅
助手柄，则要一直使用，以便最大限度控制住起动时的反弹力或反力矩。
如采取合适的预防措施，操作者就可以控制反力矩或反弹力。
b) 绝不能将手靠近旋转附件。
附件可能会反弹碰到手。
c) 不要站在发生反弹时电动工具可能移动到的地方。
反弹将在缠绕点驱使工具逆砂轮运动方向运动。

d) 当在尖角、锐边等处作业时要特别小心。避免附件的弹跳和缠绕。
尖角、锐边和弹跳具有缠绕旋转附件的趋势并引起反弹的失控。
e) 不要附装上锯链、木雕刀片或带齿锯片。
这些锯片会产生频繁的反弹和失控。
对磨削和金刚石轮切割操作的专用安全警告
a) 只使用所推荐的砂轮型号和为选用砂轮专门设计的护罩。
不是为电动工具设计的砂轮不能充分得到防护，是不安全的。
b) 护罩必须牢固地装在电动工具上，且放置得最具安全性，只有最小的砂轮部
分暴露在操作人面前。
护罩帮助保护操作者免于受到爆裂砂轮碎片和偶然触及砂轮的危险。
c) 砂轮只用作推荐的用途。例如 ：不要用切割砂轮的侧面进行磨削。
施加到砂轮侧面的力可能会使其碎裂。
d) 始终为所选砂轮选用未损坏的、有恰当规格和形状的砂轮法兰盘。
合适的砂轮法兰盘支承砂轮可以减小砂轮破裂的可能性。切割砂轮的法兰盘
可以不同于砂轮法兰盘。
e) 不要使用从大规格电动工具上用剩的磨损砂轮。
用于大规格电动工具上的砂轮不适于较小规格工具的高速工况并可能会爆
裂。
对金刚石轮切割操作的附加专用安全警告
a) 不要“夹”住切割砂轮或施加过大的压力。
不要试图做过深的切割。
给砂轮施加过应力增加了砂轮在切割时的负载，容易缠绕或卡住，增加了反
弹或砂轮爆裂的可能性。
b) 身体不要对着旋转砂轮，也不要站在其后。
当把砂轮从操作者身边的操作点移开时，可能的反弹会使旋转砂轮和电动工
具朝你推来。
c) 当砂轮被卡住或无论任何原因而中断切割时，关掉电动工具并握住工具不要
动，直到砂轮完全停止。
决不要试图当砂轮仍然运转时使切割砂轮脱离切割，否则会发生反弹。
调查并采取校正措施以消除砂轮卡住的原因。
d) 不能在工件上重新起动切割操作。让砂轮达到全速后再小心地重新进入切割。
如果电动工具在工件上重新起动，砂轮可能会卡住，爬出或反弹。
e) 支撑住板材或超大工件可使得砂轮卡住和反弹的危险降到最低限度。
大工件凭借自重而下垂。必须在工件靠近切割线处和砂轮两侧近工件边缘处
放置支承。
f) 当进行“盲切割”进入墙体或其他盲区时要格外小心。
伸出的砂轮可能会割到煤气管或水管，电线或由此引起反弹的物体。

切勿将砂轮的全表面施加于要研磨的
材料上。如图 1 所示，机器应保持
15° - 30° 使砂轮的外缘以最佳角度
与工件相接触。
3. 用新砂轮首次进行研磨时，应将角向
磨光机由对面横过工件往操作人员这
边拉，以免挖入工件（图 1 的 B 方向）。
等砂轮的前缘适当磨损后，就可往任何方向进行研磨。
4. 角向磨光机的开关
接通∶ 将开关锁往前推，接着按开关的手柄开关就被接通。
＊ 长时间使用时，只须再度将开关径前推，开关将上锁。
（＊依地区而异。）
断开∶ 按紧开关的手柄，然后释放，开关就会断开。
5. 收工后的注意事项
关掉机器之后，需等角向磨光机完全停止才能将其放下，以免造成严重事故，
而且还可以减少吸入机器的尘埃及切屑量。

b) Operations such as sanding, polishing, wire brushing or abrasive cutting-offare
not recommended to be performed with this power tool.
Operations for which the power tool was not designed may create a hazard and cause
personal injury.
c) Do not use accessories which are not specifically designed and recommended by
the tool manufacturer.
Just because the accessory can be attached to your power tool, it does not assure safe
operation.
d) 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 fly apart.
e) The outside diameter and the thickness of your accessory must be within the
capacity rating of your power tool.

f) The arbour size of wheels, flanges, backing pads or any other accessory must
properly fit the spindle of the power tool.
Accessories with arbour holes that do not match the mounting hardware of the power tool
will run out of balance, vibrate excessively and may cause loss of control.
g) 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 accessory 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 accessories will normally break apart during this test time.
h) Wear personal protective equipment. Depending on application, use face shield,
safety goggles or safety glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of stopping small abrasive or
workpiece fragments.
The eye protection must be capable of stopping flying debris generated by various
operations. The dust mask or respirator must be capable of filtrating particles generated by
your operation. Prolonged exposure to high intensity noise may cause hearing loss.
i) 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 fly away and cause injury beyond
immediate area of operation.
j) Hold power tool by insulated gripping surfaces only, when performing an operation
where the cutting accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a”live” wire may make exposed metal parts of the power tool
“live” and shock the operator.
k) Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or snagged and your hand or arm may be pulled
into the spinning accessory.

l) Never lay the power tool down until the accessory has come to a complete stop.
The spinning accessory may grab the surface and pull the power tool out of your control.
m) 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.
n) 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.
o) Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
p) 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
or any other accessory. Pinching or snagging causes rapid stalling of the rotating
accessory which in turn causes the uncontrolled 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 movement 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 firm 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 kickback 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 SPECIFIC FOR GRINDING AND
DIAMOND WHEEL CUTTING-OFF OPERATIONS
a) Use only wheel types that are recommended for your power tool and the specific
guard designed for the selected wheel.
Wheels for which the power tool was not designed cannot be adequately guarded and are
unsafe.
b) 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 operator from broken wheel fragments and accidental contact
with wheel.
c) Wheels must be used only for recommended applications. For example: do not
grind with the side of cut-offwheel.
Abrasive cut-offwheels are intended for peripheral grinding, side forces applied to these
wheels may cause them to shatter.
d) Always use undamaged wheel flanges that are of correct size and shape for your
selected wheel.
Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage.
Flanges for cut-offwheels may be different from grinding wheel flanges.
e) 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 SPECIFIC FOR
DIAMOND WHEEL CUTTING-OFF OPERATIONS
a) Do not “jam” the cut-offwheel 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 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 spinning wheel and the power tool directly at you.
c) When wheel is binding or when interrupting a cut for any reason, switch offthe
power tool and hold the power tool motionless until the wheel comes to a complete
stop. Never attempt to remove the cut-offwheel from the cut while the wheel is in
motion otherwise kickback may occur.
Investigate and take corrective 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.
