反弹是因卡住或缠绕住的旋转砂轮、靠背垫、钢丝刷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。

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。
砂磨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) 中央凹陷磨轮的磨削面必须安装在护刃器唇平面的下方。
磨轮安装不正确，通过护刃器唇平面的操作无法得到妥善保护。
c) 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。
护刃器有助于保护操作员免受破损磨轮碎片、意外接触磨轮和引燃衣物火花
的伤害。
d) 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。
e) 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。
f) 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。

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.
Incorrectly sized accessories cannot be adequately guarded or controlled.
f) Threaded mounting of accessories must match the grinder spindle thread. For
accessories mounted by flanges, the arbour hole of the accessory must fit the
locating diameter of the flange.
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.
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 the 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 could give the operator an electric shock.
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,
brush 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
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 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, accidental 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-offwheel.
Abrasive cut-offwheels are intended for peripheral grinding, side forces applied to these
wheels may cause them to shatter.
e) 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.
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.
GENERAL SAFETY INSTRUCTIONS FOR GRINDERS
— Check that speed marked on the wheel is equal to or greater than the rated speed
of the grinder;
— Ensure that the wheel dimensions are compatible with the grinder;
— Abrasive wheels shall be stored and handled with care in accordance with
manufacturer’s instructions;
— Inspect the grinding wheel before use, do not use chipped, cracked or otherwise
defective products;
— Ensure that mounted wheels and points are fitted in accordance with the
manufacturer’s instructions;
— Ensure that blotters are used when they are provided with the bonded abrasive
product and when they are required;
— Ensure that the abrasive product is correctly mounted and tightened before use
and run the tool at no-load for 30 seconds in a safe position, stop immediately if
there is considerable vibration or if other defects are detected. If this condition
occurs, check the machine to determine the cause;
— If a guard is equipped with the tool never use the tool without such a guard;

— Do not use separate reducing bushings or adapters to adapt large hole abrasive
wheels;
— For tools intended to be fitted with threaded hole wheel, ensure that the thread in
the wheel is long enough to accept the spindle length;
— Check that the work piece is properly supported;
— Do not use cutting off wheel for side grinding;
— Ensure that sparks resulting from use do not create a hazard e.g. do not hit
persons, or ignite flammable substances;
— Ensure that ventilation openings are kept clear when working in dusty conditions, if
it should become necessary to clear dust, first disconnect the tool from the mains
supply (use non metallic objects) and avoid damaging internal parts;
— Always use eye and ear protection. Other personal protective equipment such as
dust mask, gloves, helmet and apron should be worn;
