5. The rated speed of the accessory must be at
least equal to the maximum speed marked on
the po w er tool. A c c e s s o r i e s r u n n i n g f a s t e r t h a n
their rated speed can break and fly apart.
6. The outside diameter and the thickness of your
accessory must be w ithin the capacity rating
of your po w er tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
7 . The dimensions of the accessory mounting
must fit the dimensions of the mounting hard-
w are of the po w er tool. A c c e s s o r i e s t h a t d o n o t
m a t c h t h e m o u n t i n g h a r d w a r e o f t h e p o w e r t o o l
will run out of balance, vibrate excessively and
may cause loss of control.
8. Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
w heels for chips and cracks, backing pad for
cracks, tear or excess w ear, w ire brush for
loose or cracked w ires. If po w er tool or acces-
sory is dropped, inspect for damage or install
an undamaged accessory. After inspecting and
installing an accessory, position yourself and
bystanders a w ay from the plane of the rotating
accessory and run the po w er tool at maximum
no-load speed for one minute. D a m a g e d a c c e s -
sories will normally break apart during this test
t i m e .
9. Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, w ear dust mask, hearing protectors,
gloves and w orkshop apron capable of stop-
ping small abrasive or w orkpiece fragments.
The eye protection must be capable of stopping
flying debris generated by various applications.
T h e d u s t m a s k o r r e s p i r a t o r m u s t b e c a p a b l e
of filtrating particles generated by the particular
application. Prolonged exposure to high intensity
noise may cause hearing loss.
10. Keep bystanders a safe distance a w ay from
w ork area. Anyone entering the w ork area
must w ear personal protective equipment.
Fragments of workpiece or of a broken accessory
may fly away and cause injury beyond immediate
a r e a o f o p e r a t i o n .
11. Hold the po w er tool by insulated gripping
surfaces only, w hen performing an operation
w here the cutting tool may contact hidden
w iring. C o n t a c t w i t h a " l i v e " w i r e w i l l a l s o m a k e

12. Never lay the po w er tool do w n until the acces-
sory has come to a complete stop. T h e s p i n n i n g
accessory may grab the surface and pull the
power tool out of your control.
1 3 . Do not run the po w er tool w hile carrying it at
your side. A c c i d e n t a l c o n t a c t w i t h t h e s p i n n i n g

may cause electrical hazards.
15. Do not operate the power tool near flammable
materials. S p a r k s c o u l d i g n i t e t h e s e m a t e r i a l s .
16. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.

rotating accessory which in turn causes the uncon-

mum control over kickback or torque reaction
during start-up. The operator can control torque

Safety warnings specific for grinding and cut-
ting-off operations:
1. Use only wheel types that are specified
for your power tool and the specific guard
designed for the selected w heel. W h e e l s f o r

be adequately protected.
3 . The guard must be securely attached to the
po w er tool and positioned for maximum safety,
