counterclockwise.

OPERATION

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.

• ALWAYS replace wheel if tool is dropped while

grinding.

• NEVER bang or hit grinding disc or wheel onto

work.

• Avoid bouncing and snagging the wheel, especially

when working corners, sharp edges etc. This can

cause loss of control and kickback.

• NEVER use tool with wood cutting blades and other

sawblades. 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.

• Always wear safety goggles or a face shield during

operation.

• After operation, always switch off the tool and wait

until the wheel has come to a complete stop before

putting the tool down.

Grinding and sanding operation

Fig.16

ALWAYS hold the tool firmly with one hand on rear

handle and the other on the side 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 degrees to the workpiece surface.

During the break-in period with a new wheel, do not work

the grinder in the B direction or it will cut into the

workpiece. Once the edge of the wheel has been

rounded off by use, the wheel may be worked in both A

and B direction.

Operation with wire cup brush (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.

• Do not use brush that is damaged, or which is out of

balance. Use of damaged brush could increase

potential for injury from contact with broken brush

wires.

Unplug tool and place it upside down allowing easy

access to spindle. Remove any accessories on spindle.

Mount wire cup brush onto spindle and tighten with

supplied wrench. When using brush, avoid applying too

much pressure which causes over bending of wires,

leading to premature breakage.

Operation with wire wheel brush (optional

accessory)

CAUTION:

• Check operation of wire wheel brush by running

tool with no load, insuring that no one is in front of

or in line with the wire wheel brush.

• Do not use wire wheel brush that is damaged, or

which is out of balance. Use of damaged wire

wheel brush could increase potential for injury from

contact with broken wires.

• ALWAYS use guard with wire wheel brushes,

assuring diameter of wheel fits inside guard. Wheel

can shatter during use and guard helps to reduce

chances of personal injury.

Fig.18

Unplug tool and place it upside down allowing easy

access to spindle. Remove any accessories on spindle.

Thread wire wheel brush onto spindle and tighten with

the wrenches.

When using wire wheel brush, avoid applying too much

pressure which causes over bending of wires, leading to

premature breakage.

Operation with abrasive cut-off / diamond

wheel (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 European

countries, when using a diamond wheel, the

ordinary guard can be used.)

• NEVER use cut-off wheel for side grinding.

•

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.

• 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.

• 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.

• A diamond wheel shall be operated perpendicular

to the material being cut.

Mount the inner flange onto the spindle. Fit the

wheel/disc on the inner flange and screw the lock nut

onto the spindle.
