The tool is equipped with a tool/battery protection system. This system automatically cuts off power to the motor to extend tool and battery life. The tool will automatically stop during operation if the tool or battery is placed under one of the following conditions:

Overload protection: When the tool is operated in a manner that causes it to draw an abnormally high current, the tool automatically stops without any indication. In this situation, turn the tool off and stop the application that caused the tool to become overloaded. Then turn the tool on to restart.

Overheat protection: When the tool is overheated, the tool stops automatically and the battery indicator shows a blinking state ([ ] On, [ ][ ] Blinking). In this situation, let the tool cool before turning the tool on again. If the tool does not start, the battery may be overheated. In this situation, let the battery cool before starting the tool again.

Overdischarge protection: When the battery capacity is not enough, the tool stops automatically. In this case, remove the battery from the tool and charge the battery.

When the protection system works repeatedly, the tool is locked and the battery indicator shows a blinking state ([ ] On, [ ] Off, [ ][ ] Blinking). In this situation, the tool does not start even if turning the tool off and on.

To release the protection lock, remove the battery, set it to the battery charger and wait until the charging finishes.

Press the shaft lock to prevent spindle rotation when installing or removing accessories.

NOTICE: Never actuate the shaft lock when the spindle is moving. The tool may be damaged.

WARNING: Never vacuum metal particles created by grinding/cutting/sanding operation. Metal particles created by such operation are so hot that they ignite dust and the filter inside the vacuum cleaner.

To avoid dusty environment caused by masonry cutting, use a dust collecting wheel guard and a vacuum cleaner.

Refer to the instruction manual attached to the dust collecting wheel guard for assembling and using it.

Connect the hose of the vacuum cleaner to the dust collecting wheel guard attached to the tool.

WARNING: It should never be necessary to force the tool. The weight of the tool applies adequate pressure. Forcing and excessive pressure could cause dangerous wheel breakage.

WARNING: ALWAYS replace wheel if tool is dropped while grinding.

WARNING: NEVER bang or hit grinding disc or wheel onto work.

WARNING: Avoid bouncing and snagging the wheel, especially when working corners, sharp edges etc. This can cause loss of control and kickback.

WARNING: NEVER use tool with wood cutting blades and other saw blades. Such blades when used on a grinder frequently kick and cause loss of control leading to personal injury.

CAUTION: Never switch on the tool when it is in contact with the workpiece, it may cause an injury to operator.

CAUTION: Always wear safety goggles or a face shield during operation.

CAUTION: After operation, always switch off the tool and wait until the wheel has come to a complete stop before putting the tool down.

CAUTION: ALWAYS hold the tool firmly with one hand on housing and the other on the side grip (handle).

Turn the tool on and then apply the wheel or disc to the workpiece.

In general, keep the edge of the wheel or disc at an angle of about 15° to the workpiece surface.

During the break-in period with a new wheel, do not work the grinder in forward direction or it may cut into the workpiece. Once the edge of the wheel has been rounded off by use, the wheel may be worked in both forward and backward direction.

Optional accessory.

WARNING: When using an abrasive cut-off / diamond wheel, be sure to use only the special wheel guard designed for use with cut-off wheels. (In some European countries, when using a diamond wheel, the ordinary guard can be used. Follow the regulations in your country.)

WARNING: NEVER use cut-off wheel for side grinding.

WARNING: 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, wheel breakage and overheating of the motor may occur.

WARNING: Do not start the cutting operation in the workpiece. Let the wheel reach full speed and carefully enter into the cut moving the tool forward over the workpiece surface. The wheel may bind, walk up or kickback if the power tool is started in the workpiece.

WARNING: During cutting operations, never change the angle of the wheel. Placing side pressure on the cut-off wheel (as in grinding) will cause the wheel to crack and break, causing serious personal injury.

WARNING: A diamond wheel shall be operated perpendicular to the material being cut.

Follow the instructions for depressed center wheel regarding installation. The direction for mounting the lock nut and the inner flange varies by wheel type and thickness (refer to figures 19-23 in the PDF).

Optional accessory.

CAUTION: Check operation of brush by running tool with no load, insuring that no one is in front of or in line with brush.
