these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
 Maintain power tools. Check for misalignment or bind-
ing of moving parts, breakage of parts and any other
condition that may affect the power tool's operation. If
damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power
tools.
 Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind
and are easier to control.
 Use the power tool, accessories and tool bits etc. in ac-
cordance with these instructions, taking into account
the working conditions and the work to be performed.
Use of the power tool for operations different from those
intended could result in a hazardous situation.
Service
 Have your power tool serviced by a qualified repair per-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.
Safety Warnings for Cut-off Grinder
 Never stand on the power tool. Serious injuries could oc-
cur when the power tool tips over or when accidentally
coming into contact with the cutting disc.
 Always use the blade guard. A blade guard protects the
user against broken off parts of the cutting disc and against
accidental touching of the cutting disc.
 Make sure that the guard operates properly and that it
can move freely. Never lock the guard in place when
opened.
 Use the power tool only for dry cutting. Water penetrat-
ing into a power tool increases the risk of an electric shock.
 Keep the mains cable away from rotating application
tools. The mains cable can be cut through or get caught.
 Keep handles dry, clean, and free from oil and grease.
Greasy, oily handles are slippery causing loss of control.
 Never remove cutting remainders, metal chips, etc.
from the cutting area while the machine is running. Al-
ways guide the tool arm back to the neutral position first
and then switch the machine off.
 Guide the cutting disc against the workpiece only when
the machine is switched on. Otherwise, there is danger of
kickback, when the cutting disc becomes wedged in the
workpiece.
 Operate the power tool only when the work area to the
workpiece is clear of any adjusting tools, metal chips,
etc. Small pieces of metal or other objects that come in
contact with the rotating cutting disc can strike the opera-
tor with high speed.
 Always firmly clamp the workpiece. Do not cut work-
pieces that are too small to clamp. Otherwise, the clear-
ance of your hand to the rotating cutting disc is too small.
 If the cutting disc becomes jammed, switch the ma-
chine off and wait until the cutting disc comes to a com-
plete stop. Never attempt to remove a still running cut-

ting disc from the cut, otherwise there is danger of
kickback. Determine and correct the cause for the jam-
ming.
 After switching off, do not stop the cutting disc by ap-
plying lateral pressure to it. The cutting disc can become
damaged, break or lead to kickback.
 Do not force the cutting disc into the workpiece and do
not apply too much pressure when using the power
tool. Particularly avoid jamming or wedging the cutting
disc when working corners or sharp edges. When the
cutting disc is damaged due to abuse, cracks can form that
can lead to breakage without prior warning.
 Wear a work apron. Pay attention that other persons
are not put at risk from sparking. Remove flammable
materials in close vicinity. Sparking occurs when cutting
metal.
 Use the cut off grinder only for cutting materials men-
tioned under "Intended Use". Otherwise, the cut off
grinder can be subject to overload.
 Do not use damaged, out-of-centre or vibrating cutting
discs. Damaged cutting discs cause increased friction,
binding of the cutting disc and kickback.
 Always use cutting discs with correct size and shape
(diamond versus round) of arbor holes. Cutting discs
that do not match the mounting hardware of the cut off
grinder will run eccentrically, causing loss of control.
 Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kickback
and loss of control.
 Observe the operating instructions of the cut-off wheel
manufacturer for assembly and use of the cut-off
wheel. Cut-off wheels that do not fit can lead to injury as
well as to jamming, breaking or kickback.
 Do not use accessories which are not specifically de-
signed and recommended by the tool manufacturer.
Just because the accessory can be attached to your power
tool, it does not assure safe operation.
 Do not touch the cutting disc after working before it
has cooled. The cutting disc becomes very hot while work-
ing.
 Check the cable regularly and have a damaged cable re-
paired only through an authorised customer service
agent for Bosch power tools. Replace damaged exten-
sion cables. This will ensure that the safety of the power
tool is maintained.
 Store the machine in a safe manner when not being
used. The storage location must be dry and lockable.
This prevents the machine from storage damage, and from
being operated by untrained persons.
 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
 Never leave the machine before it has come to a com-
plete stop. Cutting tools that are still running can cause in-
juries.
 Never use the machine with a damaged cable. Do not
touch the damaged cable and pull the mains plug when
