are likely to run out of balance; vibrate and are likely to cause loss of control.
7- Do not use damaged accessories.
Before each use, inspect the accessories such as abrasive wheels for chips and cracks, backing
pads for cracks, tears or excess wear, wire brushes for loose or cracked wires.
If tool or accessory is dropped, inspect for damage or install an undamaged accessory.
After inspecting and installing an accessory, position yourself and any bystanders away from the
plane of the rotating accessory and run the power tool at maximum no-load speed for 1 minute.
Should accessory be damaged then it will normally break apart during this test time.
8- Wear personal protective equipment.
According to your application, use face shield, safety goggles or safety glasses.
As deemed 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
flying debris generated by various operations. The dust mask must be capable of filtrating particles
generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
9- Keep bystanders at a safe distance away from the working area. Anyone entering the work
area must wear personal protective equipment.
Fragments of workpiece or of a broken accessory
may fly away and cause injury beyond immediate area of operation.
10- Hold the power tool only by the insulated gripping surfaces when performing an operation
where the cutting accessory may contact hidden wiring.
The contact with a “live” wire may energise
metal parts of the power tool and create a shock hazard to the operator.
11- n.a.
.
12- Never lay down the power tool down until the accessory has come to a complete stop.
The
accessory may grab the surface and pull the power tool out of your control.
13- Do not run the power tool while carrying it at your side.
Accidental contact with the accessory
could snag your clothing, pulling the accessory into your body.
14- 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.
15- Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
16- Do not use accessories that require liquid coolants.
Using water or other liquid coolants may
result in electrocution or electric shock.
3.4- Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotating disk, backing pad, brush or any other
accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction opposite of the accessory’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 arms 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.
The accessory may kickback over your hand.
c- Do not position your body in the area where the power tool will move if kickback occurs.
Kickback will propel the tool in the 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
