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. 

Accessory may kickback over your 

hand.

f

Do not stand in line with the rotating grind-
ing disc. 

Kickback will propel the power tool 

in the direction opposite to the grinding 
disc’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, a segmented diamond cutting disc 
blade with segments greater than 10 mm, 
or a toothed saw blade. 

Such application 

tools create frequent kickback or loss of con-
trol over the power tool.

Additional safety warnings specific for abra-
sive 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.

f

Use extra caution when making a “pocket 
cut” into existing walls or other blind areas. 

The protruding wheel may cut gas or water 
pipes, electrical wiring or objects that can 
cause kickback.

Additional safety warnings

Wear safety goggles.

f

Use suitable detectors to determine if utili-
ty 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.

f

Release the On/Off switch and set it to the 
off position when the power supply is inter-
rupted, e. g., in case of a power failure or 
when the mains plug is pulled. 

This prevents 

uncontrolled restarting.
