10Operation with abrasive cut-off / diamond wheel (optional accessory) (Fig. 18)The direction for mounting the lock nut and the inner flange varies by wheel thickness.Refer to the table below.WARNING:• When using an abrasive cut-off / diamond wheel, besure to use only the special wheel guard designed foruse with cut-off wheels. (In some European countries,when using a diamond wheel, the ordinary guard canbe used. Follow the regulations in your country.)• NEVER use cut-off wheel for side grinding.• Do not “jam” the wheel or apply excessive pressure. Donot attempt to make an excessive depth of cut. Over-stressing the wheel increases the loading and suscepti-bility to twisting or binding of the wheel in the cut andthe possibility of kickback, wheel breakage and over-heating of the motor may occur.• Do not start the cutting operation in the workpiece. Letthe wheel reach full speed and carefully enter into thecut moving the tool forward over the workpiece surface.The wheel may bind, walk up or kickback if the powertool is started in the workpiece.• During cutting operations, never change the angle ofthe wheel. Placing side pressure on the cut-off wheel(as in grinding) will cause the wheel to crack and break,causing serious personal injury.• A diamond wheel shall be operated perpendicular tothe material being cut.MAINTENANCECAUTION:• Always be sure that the tool is switched off andunplugged before attempting to perform inspection ormaintenance.• Never use gasoline, benzine, thinner, alcohol or thelike. Discoloration, deformation or cracks may result.The tool and its air vents have to be kept clean. Regularlyclean the tool’s air vents or whenever the vents start tobecome obstructed.
