body, the possible kickback may propel the
spinning wheel and the power tool directly at you.
3.
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.
4.
Do not restart the cutting operation in the
workpiece. 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.
5.
Support panels or any oversized workpiece to
minimize 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"
6.
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause
kickback.
Safety Warnings Specific for Sanding Operations:
1.
Do not use excessively oversized sanding disc
paper. Follow manufacturers
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.
Safety Warnings Specific for Wire Brushing
Operations:
1.
Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
2.
If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel
or brush may expand in diameter due to work load
and centrifugal forces.
Additional Safety Warnings:
1.
When using depressed centre grinding wheels,
be sure to use only fiberglass-reinforced
wheels.
2.
NEVER USE Stone Cup type wheels with this
grinder. This grinder is not designed for these
types of wheels and the use of such a product may
result in serious personal injury.
3.
Be careful not to damage the spindle, the
flange (especially the installing surface) or the
lock nut. Damage to these parts could result in
wheel breakage.
4.
Make sure the wheel is not contacting the
workpiece before the switch is turned on.
5.
Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
6.
Use the specified surface of the wheel to
perform the grinding.
7.
Do not leave the tool running. Operate the tool
only when hand-held.
8.
Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
9.
Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
10.
Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
11.
Use only flanges specified for this tool.
12.
For tools intended to be fitted with threaded
hole wheel, ensure that the thread in the wheel
is long enough to accept the spindle length.
13.
Check that the workpiece is properly
supported.
14.
Pay attention that the wheel continues to rotate
after the tool is switched off.
15.
If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator
safety.
16.
Do not use the tool on any materials
containing asbestos.
17.
When use cut-off wheel, always work with the
dust collecting wheel guard required by
domestic regulation.
18.
Cutting discs must not be subjected to any
lateral pressure.
19.
Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.
