General power tool safety warnings
WARNING: Read all safety warnings and
all instructions. Failure to follow the warnings and
instructions may result in electric shock, re and/or serious injury.
Save all warnings and instruc­tions for future reference.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
Cordless grinder safety warnings
Safety Warnings Common for Grinding, Sanding, Wire Brushing, or Abrasive Cutting-Off Operations:
1. This power tool is intended to function as a grinder, sander, wire brush or cut-off tool. Read all safety warnings, instructions, illus-
trations and specications provided with this
power tool. Failure to follow all instructions listed below may result in electric shock, re and/or serious injury.
2. Operations such as polishing are not rec­ommended to be performed with this power tool. Operations for which the power tool was not
designed may create a hazard and cause per­sonal injury.
3. Do not use accessories which are not speci- cally designed and recommended by the tool manufacturer. Just because the accessory can
be attached to your power tool, it does not assure safe operation.
4. The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than
their rated speed can break and y apart.
5. The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
6. Threaded mounting of accessories must match the grinder spindle thread. For acces-
sories mounted by anges, the arbour hole of the accessory must t the locating diameter of the ange. Accessories that do not match the
mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
7.
Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accesso-
ries will normally break apart during this test time.
8. 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.
9. 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.
10. Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting tool may contact hidden wiring. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and could give the operator an electric shock.
11. 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.
7 ENGLISH
12. 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.
13. 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.
14. Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
15. Do not use accessories that require liquid coolants. Using water or other liquid coolants
may result in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel, 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.
1. 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.
2. Never place your hand near the rotating acces­sory. Accessory may kickback over your hand.
3. 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.
4. 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.
5. Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety Warnings Specic for Grinding and Abrasive
Cutting-Off Operations:
1. Use only wheel types that are recommended
for your power tool and the specic guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
2. The grinding surface of centre depressed wheels must be mounted below the plane of the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot be adequately protected.
3. 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 could
ignite clothing.
4.
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.
5. Always use undamaged wheel anges that are
of correct size and shape for your selected wheel. Proper wheel anges support the wheel
thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel anges.
6. 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.
Additional Safety Warnings Specic for Abrasive
Cutting-Off Operations:
1. 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.
2. 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.
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 correc-
tive 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.
6. 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.
Safety Warnings Specic 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.
8 ENGLISH
Safety Warnings Specic 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 berglass-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
ange (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 specied surface of the wheel to per- form 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 anges specied for this tool.
12. For tools intended to be tted 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.
SAVE THESE INSTRUCTIONS.
