carried out. This reduces the development of dust, vibra-
tions and noise to the greatest extent.
 The pneumatic tool should be set up, adjusted or used
exclusively by qualified and trained operators.
 The pneumatic tool may not be modified in any way.
Modifications can reduce the effectivity of the safety
measures and increase the risks for the operator.
Service
 Have your pneumatic tool repaired only through a qual-
ified repair person and only using original replacement
parts. This will ensure that the safety of the pneumatic tool
is maintained.
Safety warnings for pneumatic straight grinders
 Check if the type plate can be read. If required, provide
for replacement from the manufacturer.
 In case of breakage of the workpiece or an accessory,
or even of the pneumatic tool itself, parts can be
thrown about at high speed.
 During operation, repairs or maintenance, and when
replacing accessories on the pneumatic tool, always
wear shock-resistant eye protection. The degree of the
required protection should be separately evaluated for
each individual application.
 Regularly measure the no-load speed of the grinder
spindle. If the measured value of the specified no-load
speed exceeds n (see "Technical Data"), you should
0
have the pneumatic tool checked at a Bosch after-sales
centre. If the no-load speed is too high, the application
tool can break; if the speed is too low, the performance de-
creases.
 The permitted speed of the application tool must be at
least as high as the maximum speed specified on the
pneumatic tool, taking into account the inner shank di-
mension L . Accessories rotating faster than their permit-
0.
ted speed can break and fly around.
 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.
 Avoid contact with the tool holder and the application
tool. You may be injured.
 Caution! Application tools can become hot during pro-
longed operation of the pneumatic tool. Wear protective
gloves.
 Wear close-fitting gloves. The flow of compressed air
makes the handles of pneumatic tools cold. Warm hands
are less sensitive to vibrations. Loose fitting gloves can be
caught by rotating parts.
 The operators and the maintenance personnel must be
physically capable to handle the size, weight and pow-
er of the pneumatic tool.
 Be prepared for unexpected movements of the pneu-
matic tool that can develop owing to reaction forces or
breakage of the application tool. Maintain a firm grip

on the pneumatic tool and position your body and arms
to allow you to resist such movements. These precau-
tions can prevent injuries.
 When working with this pneumatic tool, assume a com-
fortable stance, hold the tool securely and avoid unfa-
vourable positions or such positions, where it is diffi-
cult to keep your balance. For prolonged work, the
operator should change the stance or posture, which
can help avoid discomfort and fatigue.
 In case of an interruption of the air supply or reduced
operating pressure, switch the pneumatic tool off.
Check the operating pressure and start again when the op-
erating pressure is optimal.
 Use only the lubricants recommended by Bosch.
 If you want to operate the pneumatic tool in a suspen-
sion device or a clamping fixture, take care to fasten it
in the device/fixture first before connecting it to the air
supply. This measure prevents accidental starting of oper-
ation.
 Wear a hard hat when carrying out work overhead. This
prevents injuries.
 Never lay the pneumatic tool down until the application
tool has come to a complete stop. The spinning applica-
tion tool may come into contact with the surface and pull
the pneumatic tool out of your control.
 When using the pneumatic tool for the performance of
work-related activities, the operator may experience
unpleasant sensations in the hands, arms, shoulders,
neck area or other body parts.
 Should the operator perceive symptoms such as persis-
tent nausea, discomfort, throbbing, pain, tingling,
numbness, burning or stiffness, these warning signs
should not be ignored. The operator should notify his
employer about the symptoms and consult a qualified
physician.
 Do not use grinding wheels, cutting wheels or milling
cutters. These application tools can break and fly around
and cause serious injury.
 Do not use any damaged application tools. Before eve-
ry use, check application tools for chips and cracks,
abrasion or excessive wear. If the pneumatic tool or the
application tool falls, check whether it is damaged or
use an undamaged application tool. When you have
checked and inserted the application tool, keep your-
self and bystanders away from the vicinity of the spin-
ning application tool and leave the power tool to run for
a minute at maximum speed. Damaged accessories usu-
ally break during this test time.
 Only use application tools with an appropriate shank
diameter. An application tool with a shank diameter
which does not correspond to the tool holder of the tool
(see "Technical Data"), cannot be held properly and will
damage the collet chuck.
 Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility com-
pany for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
