The arbour size of wheels and anges must properly t the
spindle of the power tool. Wheels and anges with arbour holes
that do not match the mounting hardware of the power tool will run
out of balance, vibrate excessively and may cause loss of control.
Do not use damaged wheels. Before each use, inspect
the wheels for chips and cracks. If power tool or wheel is
dropped, inspect for damage or install an undamaged wheel.
After inspecting and installing the wheel, position yourself
and bystanders away from the plane of the rotating wheel
and run the power tool at maximum no load speed for one
minute. Damaged wheels will normally break apart during this
test time.
Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing protectors, gloves
and workshop apron capable of stopping small abrasive or
workpiece fragments. The eye protection must be capable of
stopping ying debris generated by various operations. The dust
mask or respirator must be capable of ltrating particles generated
by your operation. Prolonged exposure to high intensity noise may
cause hearing loss.
Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal
protective equipment. Fragments of workpiece or of a broken
accessory may y away and cause injury beyond immediate area of
operation.
Hold power tool by insulated gripping surfaces when
performing an operation where the cutting tool may contact
hidden wiring or its own cord. Contact with a live wire will also
make exposed metal parts of the power tool live and shock the
operator.
Position the cord clear of the spinning accessory. If you lose
control of the power tool, the cord may be cut or snagged and your
hand or arm may be pulled into the spinning accessory.
Never lay the power tool down until the accessory has come
to a complete stop. The spinning accessory may grab the surface
and pull the power tool out of your control.
Do not run the power tool while carrying it at your side.
Accidental contact with the spinning accessory could snag your
clothing, pulling the accessory into your body.
Regularly clean the power tool’s air vents. The motor’s fan will
draw the dust inside the housing and excessive accumulation of
powdered metal may cause electrical hazards.
Do not operate the power tool near ammable materials.
Sparks could ignite these materials.
Do not use accessories that require liquid coolants. Using water
or other liquid coolants may result in electrocution or shock.
Causes and operator prevention of kickback:
Kickback is a sudden reaction to a pinched or snagged rotating wheel.
Pinching or snagging causes rapid 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.
Maintain a rm 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.
Never place your hand near the rotating accessory. Accessory
may kickback over your hand.
Do not position your body in the area where power tool will
move if kickback occurs. Kickback will propel the tool in direction
opposite to the wheel’s movement at the point of snagging.
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.
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.
Do not jam the cut-o 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.
When wheel is binding or when interrupting a cut for any
reason, switch o the power tool and hold the power tool
motionless until the wheel comes to a complete stop. Never
attempt to remove the cut-o 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.
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.
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” into existing
walls or other blind areas. The protruding wheel may cut gas or
water pipes, electrical wiring or objects that can cause kickback.
SPECIFIED CONDITIONS OF USE
This electronic bercement saw can be used to cut wood or bre
cement with a circular saw blade. It can alternatively be used to cut
stone with a diamant cutt-o wheel.
