• Use suitable detectors to determine if utility lines are 

hidden in the work area or call the local utility company 

for assistance . Contact with electric lines can lead to 

fire and electric shock . Damaging a gas line can lead 

to explosion . Penetrating a water line causes property 

damage or may cause an electric shock .

• Switch off the power tool immediately when the tool 

insert jams . Be prepared for high reaction torque that 

can cause kickback . The tool insert jams when: 

– the power tool is subject to overload

– it becomes wedged in the workpiece .

• Hold the machine with a firm grip . High reaction torque 

can briefly occur while driving in and loosening screws .

• When working with the machine, always hold it firmly 

with both hands and provide for a secure stance . The 

power tool is guided more secure with both hands .

• Secure the workpiece . A workpiece clamped with 

clamping devices or in a vice is held more secure than 

by hand .

• Do not open the battery . Danger of short-circuiting .

• Protect the battery against heat, e . g ., against continu-

ous intense sunlight, fire, water, and moisture . Danger 

of explosion .

• In case of damage and improper use of the battery, 

vapours may be emitted . Ventilate the area and seek 

medical help in case of complaints . The vapours can 

irritate the respiratory system .

• Use the battery only in conjunction with your power 

tool . This measure alone protects the battery against 

dangerous overload .

• The battery can be damaged by pointed objects such as 

nails or screwdrivers or by force applied externally . An 

internal short circuit can occur and the battery can burn, 

smoke, explode or overheat .

Kickback and related warnings

• Kickback is a sudden reaction to a pinched or snagged

rotating wheel, backing pad, brush or any other acces-

sory . Pinching or snagging causes rapid stalling of the 

rotating accessory which in turn causes the uncontrolled 

power tool to be forced in the direction opposite of the 

accessory’s rotation at the point of the binding . For ex-

ample, if an abrasive wheel is snagged or pinched by the 

workpiece, the edge of the wheel that is entering into the 

pinch point can dig into the surface of the material caus-

ing the wheel to climb out or kick out . The wheel may 

either jump toward or away from the operator, depend-

ing on direction of the wheel’s movement at the point 

of pinching . Abrasive wheels may also break under these 

conditions . Kickback is the result of power tool misuse 

and/or incorrect operating procedures or conditions and 

can be avoided by taking proper precautions as given 

below .

• Maintain a firm grip on the power tool and position your 

body and arm to allow you to resist kickback forces . Al-

ways use auxiliary handle, if provided, for maximum con-

trol over kickback or torque reaction during start-up . The 

operator can control torque reactions or kickback forces, 

if proper precautions are taken .

• Never place your hand near the rotating accessory . Ac-

cessory may kickback over your hand .

• Do not position your body in the area where power tool 

will move if kickback occurs . Kickback will propel the tool 

in direction opposite to the wheel’s movement at the 

point of snagging .

• Use special care when working corners, sharp edges, etc . 

Avoid bouncing and snagging the accessory . Corners, 

sharp edges or bouncing have a tendency to snag the 

rotating accessory and cause loss of control or kickback .

• Do not attach a saw chain woodcarving blade or toothed 

saw blade . Such blades create frequent kickback and loss 

of control .

Safety warnings specific for Grinding 

and Abrasive Cutting-Off operations

• Use only wheel types that are recommended for your

power tool and the specific guard designed for the se-

lected wheel . Wheels for which the power tool was not 

designed cannot be adequately guarded and are unsafe .

• The grinding surface of the centre depressed wheels

must be mounted below the plane of the guard lip . An 

improperly mounted wheel that projects through the 

plane of the guard lip cannot be adequately protected .

• The guard must be securely attached to the power tool

and positioned for maximum safety, so the least amount 

of wheel is exposed towards the operator . The guard 

helps to protect operator from broken wheel fragments, 

accidental contact with wheel and sparks that could ig-

nite clothing .

• Wheels must be used only for recommended applica-

tions . 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 .

• Always use undamaged wheel flanges that are of correct 

size and shape for your selected wheel . Proper wheel 

flanges support the wheel thus reducing the possibility 

of wheel breakage . Flanges for cut-off wheels may be dif-

ferent from grinding wheel flanges .

• Do not use worn down reinforced 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

• Do not “jam” the cut-off wheel or apply excessive pres-

sure . Do not attempt to make an excessive depth of cut . 

Overstressing the wheel increases the loading and sus-

ceptibility to twisting or binding of the wheel in the cut 

and the possibility of kickback or wheel breakage .

• Do not position your body in line with and behind the

rotating wheel . When the wheel, at the point of opera-

tion, is moving away from your body, the possible kick-

back may propel the spinning wheel and the power tool 

directly at you .

• When wheel is binding or when interrupting a cut for any 

reason, switch off the power tool and hold the power tool 

motionless until the wheel comes to a complete stop . 

Never attempt to remove the cut-off wheel from the cut 

while the wheel is in motion otherwise kickback may oc-

cur . Investigate and take corrective action to eliminate 

the cause of wheel binding .

• Do not restart the cutting operation in the workpiece . Let 

the wheel reach full speed and carefully re-enter the cut .
