IMPORTANT SAFETY CONSIDERATIONS

• Stay alert, watch what you are doing and use common sense when operating the Angle

Grinder. Do not use the Angle Grinder while you are tired or under the influence of drugs,

alcohol or medication. A moment of inattention while operating the Angle Grinder may result

in serious personal injury.

• Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair,

clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be

caught in moving parts. Air vents often cover moving parts and should be avoided.

• Use safety apparel and equipment. Use ANSI-approved safety goggles or safety glasses

with side shields, or when needed, a face shield. Use as dust mask in dusty work conditions.

This applies to all persons in the work area. Also use non-skid safety shoes, hardhat, gloves,

dust collection systems, and hearing protection when appropriate.

• Do not overreach. Keep proper footing and balance at all times.

• Remove adjusting keys or wrenches before connecting to the power supply or turning on

the tool. A wrench or key that is left attached to a rotating part of the tool may result in

personal injury.

ANGLE GRINDER USE AND CARE

• Do not modify the Angle Grinder in any way. Unauthorized modification may impair the

function and/or safety and could affect the life of the equipment. There are specific

applications for which Angle Grinder was designed.

• Always check of damaged or worn out parts before using the Angle Grinder. Broken

parts will affect the Angle Grinder operation. Replace or repair damaged or worn parts

immediately.

• Store idle Angle Grinder. When Angle Grinder is not in use, store it in a secure place out

of the reach of children. Inspect it for good working condition prior to storage and before

reuse.

• When operating the tool

Check that the switch is in the off position “O” before connecting to the power supply. Switch

to the off position “O” immediately after completion of the task.

Keep the power cord away from any moving parts or accessories.

Never cover the ventilation slots in the tool.

Inspect the disc before use. Do not use a chipped, cracked or otherwise damaged product.

Always hold the body and auxiliary handle firmly. Otherwise, the counterforces produced

during use can cause inaccuracies or put the Angle Grinder out of control.

Do not use separate adaptors to try and fit a disc with a center hole larger than 5/8in.
Be aware that a disc will continue to turn for some seconds after it is switched off.

• Use only wheel types that are recommended for your power tool and specific guard

designed for the selected wheel. Wheels for which the power tool was not designed

cannot be adequately guarded and are unsafe.

• 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 operator from broken wheel fragments and accidental contact with the wheel.

• 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.

• 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.

• Do not use worn down wheels from larger power tools. A wheel intended for a larger

power tool is not suitable for the higher speed of a smaller tool and may burst.

• 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.

• 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.

• 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.

• Do not restart the cutting operation in the work piece. 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 work piece.

• Support panels or any oversized work piece to minimize the risk of wheel pinching

and kickback. Large work pieces tend to sag under their own weight. Supports must be

placed under the work piece near the line of cut and near the edge of the work piece 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 pipe, electrical wiring or objects that can cause

kickback.

• Do not use excessively oversized sanding disc paper. Follow manufacturer’s

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.

• WARNING! Be sure to disconnect the Angle Grinder from the power supply

before attaching or removing the disc or attachment.

Make sure that a grinding disc is mounted with the label on top or facing the Angle Grinder.

If you are fitting any other kind of attachment, refer to attachment fitment Instructions. The

distributor will not be responsible for any damage or injury caused due to the incorrect

fitment of grinding discs or any other kind of attachment.

Incorrect attachments can cause the motor to burn out, generally damage the tool or cause

injury.

Your Angle Grinder has been designed to grind all types of material when used in a DIY (Do

It Yourself) context or for hobbyist purposes. It is not built for continuous daily use in a trade

of professional capacity.
