Bosch Power Tools

f

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 re-

actions or kickback forces, if proper precau-

tions are taken.

f

Never place your hand near the rotating ac-

cessory. 

The accessory may kickback over 

your hand.

f

Do not position your body in the area where 

the power tool will move if kickback occurs. 

Kickback will propel the tool in the direction 

opposite to the wheel’s movement at the 

point of snagging.

f

Use special care when working corners, 

sharp edges, etc. Avoid bouncing and snag-

ging the accessory. 

Corners, sharp edges or 

bouncing have a tendency to snag the rotat-

ing accessory and cause loss of control or 

kickback.

f

Do not attach a saw chain woodcarving 

blade or toothed saw blade. 

Such blades 

create frequent kickback and loss of control 

over the power tool.

Additional safety instructions for grind-

ing and cutting off operations

f

Use only wheel types that are recommend-

ed for your power tool and the specific 

guard designed for the selected wheel. 

Wheels for which the power tool was not de-

signed cannot be adequately guarded and 

are unsafe.

f

The guard must be securely attached to the 

power tool and positioned for maximum safe-

ty, so the least amount of wheel is exposed 

towards the operator. 

The guard helps to pro-

tect operator from broken wheel fragments 

and accidental contact with wheel.

f

Wheels must be used only for recommend-

ed applications. 

For example: do not grind 

with the side of the cut-off wheel. Abrasive 

cut-off wheels are intended for peripheral 

grinding; side forces applied to these wheels 

may cause them to shatter.

f

Always use undamaged wheel flanges that 

are of correct size and shape for your se-

lected wheel. 

Proper wheel flanges support 

the wheel thus reducing the possibility of 

wheel breakage. Flanges for cut-off wheels 

may be different from grinding wheel flanges.

f

Do not use worn down wheels from larger 

power tools. 

Wheels intended for larger 

power tools are not suitable for the higher 

speed of a smaller tool and may burst.

Additional safety warnings specific for 

abrasive cutting off operations

f

Do not “jam” the cut-off wheel or apply ex-

cessive pressure. Do not attempt to make 

an excessive depth of cut. 

Overstressing the 

wheel increases the loading and susceptibili-

ty to twisting or binding of the wheel in the 

cut and the possibility of kickback or wheel 

breakage.

f

Do not position your body in line with and 

behind the rotating wheel. 

When the wheel, 

at the point of operation, is moving away 

from your body, the possible kickback may 

propel the spinning wheel and the power 

tool directly at you.

f

When wheel is binding or when interrupting 

a cut for any reason, switch off the power 

tool and hold the power tool motionless un-

til the wheel comes to a complete stop. Nev-

er attempt to remove the cut-off wheel from 

the cut while the wheel is in motion, other-

wise kickback may occur. 

Investigate and 

take corrective action to eliminate the cause 

of wheel binding.

f

Do not restart the cutting operation in the 

workpiece. Let the wheel reach full speed 

and carefully reenter the cut. 

The wheel may 

bind, walk up or kickback if the power tool is 

restarted in the workpiece.

f

Support panels or any oversized workpiece 

to minimize the risk of wheel pinching and 

kickback. 

Large workpieces tend to sag un-

der their own weight. Supports must be 

placed under the workpiece near the line of 

cut and near the edge of the workpiece on 

both sides of the wheel.
