stalling of the rotating wheel which in turn causes the
uncontrolled power tool to be forced in the direction
opposite of the wheel’s rotation at the point of the
binding.
For example, if an abrasive wheel is snagged or pinched
by the workpiece, the edge of the wheel that is entering
into the pinch point can dig into the surface of the
material causing the wheel to climb out or kick out. The
wheel may either jump toward or away from the operator,
depending on direction of the wheel’s movement at the
point of pinching. Abrasive wheels may also break under
these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or kickback
forces, if proper precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your hand.
c) Do not position your body in line with the
rotating wheel. Kickback will propel the tool in
direction opposite to the wheel’s movement at the point
of snagging.
d) Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
accessory.
Corners, sharp edges or bouncing have a
tendency to snag the rotating accessory and cause loss
of control or kickback.
e) Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral
gap greater than 10 mm or toothed saw blade.
Such blades create frequent kickback and loss of
control.
f) Do not “jam” the 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.
g) 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 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.
h) 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.
i) 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.
j) 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.
ADDITIONAL SAFETY RULES:
1. Always wear a dust mask.
ADDITIONAL SAFETY RULES
FOR YOUR CIRCULAR SAW
1. Use only saw blades recommended by the
manufacturer, which conform to EN 847-1, if
intended for wood and analogous materials.
2. Do not use any abrasive wheels.
3. Use only blade diameter(s) in accordance with the
markings.
4. Identify the correct saw blade to be used for the
material to be cut.
5. Use only saw blades that are marked with a speed
equal or higher than the speed marked on the tool.
GENERAL SAFETY WARNINGS
FOR YOUR LASER
WARNING: Read all safety warnings and all
instructions.
Failure to follow the warnings and
instructions may result in serious injury.
Save all warnings and instructions for future reference.
These lasers do not normally present an optical hazard
although staring at the beam may cause flash blindness.
Do not stare directly at the laser beam. A hazard may
exist if you deliberately stare into the beam, please
observe all safety rules as follows:
1. The laser shall be used and maintained in
accordance with the manufacturer’s instructions.
2. Never aim the beam at any person or an object other
than the work piece.
3. The laser beam shall not be deliberately aimed at
another person and shall be prevented from being
directed towards the eye of a person for longer than
0.25 seconds area.
4. Always ensure the laser beam is aimed at a sturdy
work piece without reflective surfaces, e.g. wood
or rough-coated surfaces are acceptable. Bright
shiny reflective sheet steel or similar is not suitable
for laser applications as the reflective surface may
direct the laser beam back at the operator.
5. Do not change the laser device with a different type.
The manufacturer or an authorized agent must carry
out repairs.
6. CAUTION: Use of controls or adjustments other
than those specified herein may result in hazardous
radiation exposure.
Additional safety warning for class 2 laser
The laser device fitted to this tool is CLASS 2 with a
maximum radiation of 1.5mW and 650nm wavelength.
CLASS 2 LASER RADIATION,DO NOT STARE INTO
