Wheels must be used only for recommended applications. For example: do not grind
with the side of 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 different from grinding wheel flanges.
Do not use worn down wheels from larger power tools. A wheel intended for a larger
power tool is not suitable for the higher speed of a smaller tool and may burst.
Do not "jam" the cut-off wheel or apply excessive pressure. Do not attempt to make
an excessive depth of cut. Overstressing the wheel increases the loading and
susceptibility 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 operation, is moving away from your body, the possible kickback 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 occur. Investigate and take corrective action to eliminate the cause
of wheel binding.
Do not restart the cutting operation in the work piece. 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 work piece.
Support panels or any oversized work piece to minimize the risk of wheel pinching
and kickback. Large work pieces tend to sag under their own weight. Supports must be
placed under the work piece near the line of cut and near the edge of the work piece on
both sides of the wheel.
Use extra caution when making a "pocket cut" into existing walls or other blind areas.
The protruding wheel may cut gas or water pipe, electrical wiring or objects that can cause
kickback.
Do not use excessively oversized sanding disc paper. Follow manufacturer's
recommendations when selecting sanding paper. Larger sanding paper extending beyond
the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc
or kickback.
WARNING! Be sure to disconnect the Angle Grinder from the power supply
before attaching or removing the disc or attachment.
Make sure that a grinding disc is mounted with the label on top or facing the Angle Grinder.
If you are fitting any other kind of attachment, refer to attachment fitment Instructions. The
distributor will not be responsible for any damage or injury caused due to the incorrect
fitment of grinding discs or any other kind of attachment.
Incorrect attachments can cause the motor to burn out, generally damage the tool or cause
injury.
Your Angle Grinder has been designed to grind all types of material when used in a DIY (Do
It Yourself) context or for hobbyist purposes. It is not built for continuous daily use in a trade
of professional capacity.
