ADDITIONAL SAFETY INSTRUCTIONS FOR GRINDING AND CUTTING-OFF OPERATIONS
Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations:
a) Use only disc types that are recommended for your power tool and the specific guard designed for the
selected disc. Discs for which the power tool was not designed cannot be adequately guarded and are unsafe.
b) The grinding surface of centre depressed discs must be mounted below the plane of the guard lip. An
improperly mounted disc that projects through the plane of the guard lip cannot be adequately protected.
c) The guard must be securely attached to the power tool and positioned for maximum safety, so the least
amount of disc is exposed towards the operator. The guard helps to protect the operator from broken disc fragments,
accidental contact with disc and sparks that could ignite clothing.
d) Discs must be used only for recommended applications. For example: do not grind with the side of
cut-off disc. Abrasive cut-off discs are intended for peripheral grinding, side forces applied to these discs may cause them to
shatter.
e) Always use undamaged disc flanges that are of correct size and shape for your selected disc. Proper disc
flanges support the disc thus reducing the possibility of disc breakage. Flanges for cut-off discs may be different from grinding
disc flanges.
f) Do not use worn down discs from larger power tools. Disc intended for larger power tool is not suitable for the
higher speed of a smaller tool and may burst.
Additional Safety Warnings Specific for Abrasive Cutting-Off Operations:
a) Do not "jam" the cut-off disc or apply excessive pressure. Do not attempt to make an excessive depth
of cut. Overstressing the disc increases the loading and susceptibility to twisting or binding of the disc in the cut and the
possibility of kickback or disc breakage.
b) Do not position your body in line with and behind the rotating disc. When the disc, at the point of operation, is
moving away from your body, the possible kickback may propel the spinning disc and the power tool directly at you.
c) When disc is binding or when interrupting a cut for any reason, switch off the power tool and hold the
power tool motionless until the disc comes to a complete stop. Never attempt to remove the cut-off disc
from the cut while the disc is in motion otherwise kickback may occur. Investigate and take corrective action to
eliminate the cause of disc binding.
d) Do not restart the cutting operation in the workpiece. Let the disc reach full speed and carefully re-enter
the cut. The disc may bind, walk up or kickback if the power tool is restarted in the workpiece.
e) Support panels or any oversized workpiece to minimize the risk of disc 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 disc.
f) Use extra caution when making a "pocket cut" into existing walls or other blind areas. The protruding disc
may cut gas or water pipes, electrical wiring or objects that can cause kickback.
g) Check 'use-by' date on disc. Do not use out of date accessories.
