loss of control or kickback.
e- Do not attach a saw chain woodcarving blade or toothed saw blade.
Such blades create frequent
kickback and loss of control over the power tool.
3.5- Specific Safety Instructions for grinding and cutting operation
a- Use only disk types that are recommended for your tool and the specific guard designed for the
selected disk.
Disks
for which the tool was not designed cannot be adequately guarded and are unsafe.
b- 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 and accidental contact with wheel and sparks that could ignite clothing.
c- Disks must be used only for their recommended applications.
For example: do not grind with the
side of the cut-off disk. Abrasive cut-off disks are intended for peripheral grinding; side forces applied
to these disks may cause them to shatter.
d- Always use undamaged disk flanges that are of correct size and shape for your selected disk.
Proper disk flanges support the disk thus reducing the possibility of disk breakage. Flanges for cut-off
disks may be different from grinding disk flanges.
e- Do not use worn out disks from larger power tools.
Disks intended for larger power tools are not
suitable for the higher speed of a smaller tool and may burst.
3.6- Specific Safety Instructions for abrasive cutting operations
a- Do not “jam” the cut-off disk or apply excessive pressure. Do not attempt to make an excessive
depth cut.
Overstressing the disk increases the loading and susceptibility to twisting or binding of the
disk in the cut and the possibility of kickback or disk breakage.
b- Do not position your body in line with and behind the rotating disk.
When the disk, at the point of
operation, is moving away from your body, the possible kickback may propel the rotating disk and the
tool directly at you.
c- When the disk is binding or when you interrupt a cut for any reason, switch off the power tool
and hold the power tool motionless until the rotating disk comes to a complete stop. Never
attempt to remove the cut-off disk from the cut while the disk is still in motion, otherwise
kickback may occur.
Investigate and take corrective action to eliminate the cause of disk binding.
d- Do not restart the cutting operation in the workpiece. Let the disk reach full speed and
carefully re-enter the cut.
The disk 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 disk 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 disk.
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.
3.7- Specific Safety Instructions for sanding operations
Do not use oversized sandpaper pads for sanding discs.
Follow manufacturers' recommendations when selecting sandpaper.
Larger sandpaper protruding beyond the sanding pad presents a laceration hazard and may cause a
fixing, tear the disc or a kickback.
3.8- Specific Safety Instructions for wire brush operations
a- Keep in mind that metal strands are ejected by the wire brush even during ordinary operation.
Do not subject the metal wires to excessive stress by applying excessive load onto the brush.
