Additional Safety Instructions For Grinding And Cutting- Off Operations - Worx Professional WU820 Manual

woodcarving blade or toothed saw
blade. Such blades create frequent kickback
and loss of control.

INSTRUCTIONS FOR
GRINDING AND CUTTING-
OFF OPERATIONS
Safety Warnings Specific for Grinding
and Abrasive Cutting-Off Operations:
a) Use only wheel types that are
recommended for your power tool
and the specific guard designed for
the selected wheel. Wheels for which
the power 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
the operator from broken wheel fragments,
accidental contact with wheel and sparks that
EN
could ignite clothing.

c) 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.
d) 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.
e) Do not use worn down wheels from
larger power tools. Wheel intended for
larger power tool is not suitable for the higher
speed of a smaller tool and may burst.

INSTRUCTIONS FOR
CUTTING-OFF OPERATIONS
Additional Safety Warnings Specific for
Abrasive Cutting-Off Operations:
a) 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.
b) 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.
c) 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.
d) Do not restart the cutting operation
in the workpiece. 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 workpiece.
e) 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.
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.

INSTRUCTIONS
1. Power tools should be fed only from the
mains source through the circuit breaker
to a leakage current, operating at a current
of no more than 0.03 amperes. Check the
safety of the circuit breaker once a month
using the control button.
2. Goggles and hearing protection should be
