cessory which in turn causes the uncontrolled power tool to
be forced in the direction opposite of the accessory's rota-
tion.
For example, 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 causing
the wheel to climb out or kick out. The wheel may either
jump toward or away from the operator, depending on direc-
tion of the wheel's movement at the point of pinching. Abras-
ive 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
u
your body and arm to allow you to resist kickback
forces. The operator can control kickback forces, if
proper precautions are taken.
Use special care when working corners, sharp edges
u
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 toothed saw blade. Such blades create
u
frequent kickback and loss of control.
Always feed the bit into the material in the same dir-
u
ection as the cutting edge is exiting from the material
(which is the same direction as the chips are thrown).
Feeding the tool in the wrong direction causes the cutting
edge of the bit to climb out of the work and pull the tool in
the direction of this feed.
When using rotary files, high-speed cutters or tung-
u
sten carbide cutters, always have the work securely
clamped. These wheels will grab if they become slightly
canted in the groove, and can kickback.When the rotary
file, high-speed cutter or tungsten carbide cutter grab, it
may jump from the groove and you could lose control of
the tool.
Safety warnings specific for grinding and abrasive
cutting-off operations
Use only wheel types that are recommended for your
u
power tool and only for recommended applications.
For example: do not grind with the side of a cut-off
wheel. Abrasive cut-off wheels are intended for peri-
pheral grinding, side forces applied to these wheels may
cause them to shatter.
For threaded abrasive cones and plugs use only un-
u
damaged wheel mandrels with an unrelieved shoulder
flange that are of correct size and length. Proper man-
drels will reduce the possibility of breakage.
Do not "jam" a cut-off wheel or apply excessive pres-
u
sure. Do not attempt to make an excessive depth of
cut. Overstressing the wheel increases the loading and
susceptibility to twisting or snagging of the wheel in the
cut and the possibility of kickback or wheel breakage.
Do not position your hand in line with and behind the
u
rotating wheel. When the wheel, at the point of opera-
Bosch Power Tools
tion, is moving away from your hand, the possible kick-
back may propel the spinning wheel and the power tool
directly at you.
When wheel is pinched, snagged or when interrupting
u
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 occur. Investigate and take
corrective action to eliminate the cause of wheel pinching
or snagging.
Do not restart the cutting operation in the workpiece.
u
Let the wheel reach full speed and carefully re-enter
the cut. The wheel may bind, walk up or kickback if the
power tool is restarted in the workpiece.
Support panels or any oversized workpiece to minim-
u
ize the risk of wheel pinching and kickback. Large
workpieces tend to sag under 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.
Use extra caution when making a "pocket cut" into ex-
u
isting walls or other blind areas. The protruding wheel
may cut gas or water pipes, electrical wiring or objects
that can cause kickback.
Additional safety information
Do not touch grinding discs until they have cooled
u
down. The discs can become very hot while working.
Use suitable detectors to determine if utility lines are
u
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
explosion. Penetrating a water line causes property dam-
age or may cause an electric shock.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than by
hand.
This power tool is not suitable for bench-mounted use.
u
It must not be clamped into a vice or fastened to a work-
bench, for example.
Products sold in GB only:
Your product is fitted with an BS 1363/A approved electric
plug with internal fuse (ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an au-
thorised customer service agent. The replacement plug
should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains
socket elsewhere.
