–
Do not use separate reducing bushings or adapters to
adapt large hole abrasive wheels;
–
For tools intended to be fi tted with threaded hole wheel,
ensure that the thread in the wheel is long enough to
accept the spindle length;
–
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 fl ammable
substances;
–
Ensure that ventilation openings are kept clear when
working in dusty conditions, if it should become
necessary to clear dust, fi rst 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;
–
Pay attention to the wheel that continues to rotate after
the tool is switched off .
–
When using dual-purpose (combined grinding and
cut-off wheels), use only the type A wheel guard (See
page 174)
–
When using a type A wheel guard for lateral grinding,
the guard may interfere with the workpiece causing poor
control.
–
When using a type B wheel guard for cutting-off
operations with bonded cut-off wheels, there is an
increased risk of exposure to emitted sparks and
particles, as well as exposure to wheel fragments in the
event of a wheel burst.
–
When using a type A, B wheel guard for cutting-off
operations or lateral grinding in concrete or masonry,
there is an increased risk of exposure to dust and loss of
control resulting in kickback.
–
Do not use any segmented diamond cut-off wheels with
segment slits >10 mm. Only negative segment cutting
angles are permitted.
–
The workpiece must lay fl at and be secured against
slipping, e.g. using clamps. Large workpieces must be
suffi ciently supported.
–
Observe the specifi cations of the tool or accessory
manufacturer. Protect wheels from grease or impact.
–
Accessories must be stored and handled with care in
accordance with the manufacturer's instructions.
WARNING
–
When using a cutting-off wheel, be sure to attach a type
A wheel guard.
–
When using a grinding wheel, be sure to attach a type B
wheel guard.
–
For safety reasons, only use the wheel guard provided
for the respective accessory. Using an incorrect wheel
guard can lead to loss of control and serious injuries.

ADDITIONAL SAFETY WARNINGS
1. Ensure that the power source to be utilized conforms
to the power requirements specifi ed on the product
nameplate.
2. 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, which could cause a serious accident.
3. When the work area is removed from the power source,
use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Ensure that the depressed center wheel to be utilized is
the correct type and free of cracks or surface defects.
Also ensure that the depressed center wheel is properly
mounted and the wheel nut is securely tightened.
5. Confi rm that the push button is disengaged by pushing
push button two or three times before switching the
power tool on.
6. To prolong the life of the machine and ensure a fi rst
class fi nish, it is important that the machine should not
be overloaded by applying too much pressure. In most
applications, the weight of the machine alone is suffi cient
for eff ective grinding. Too much pressure will result in
reduced rotational speed, inferior surface fi nish, and
overloading which could reduce the life of the machine.
7. The wheel continues to rotate after the tool is switched
off .
After switching off the machine, do not put it down until
the depressed center wheel has come to a complete
stop. Apart from avoiding serious accidents, this
precaution will reduce the amount of dust and swarf
sucked into the machine.
8. When the machine is not use, the power source should
be disconnected.
9. Be sure to switch OFF and disconnect the attachment
plug from the receptacle to avoid a serious accident
before the depressed center wheel is assembling and
disassembling.
10. Caution when using near welding equipment
When using the grinder in the immediate vicinity of
welding equipment, the rotational speed may become
unstable. Do not use the grinder near welding equipment.
11. RCD
The use of a residual current device with a rated residual
current of 30 mA or less at all times is recommended.
12. Be careful of brake kickback.
This disc grinder features an electric brake that functions
when the switch is released. As there is some kickback
when the brake functions, be sure to hold the main body
securely.
13. Do not operate from a direct current power source,
booster or any other type of transformer. Doing so may
not only cause damage to the grinder, but may lead to
accidents.
14. Some mobile generators may not be usable with the
machine.
