ENGLISH

5. 

Do not attach a saw chain woodcarving blade, 
segmented diamond wheel with a peripheral 
gap greater than 10 mm or toothed saw blade.

Such blades create frequent kickback and loss of 
control.

Safety warnings specific for grinding and cutting-off 

operations:

1. 

Use only wheel types that are specified 

for your power tool and the specific 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, acci-
dental contact with wheel and sparks that could 
ignite clothing.

4. 

Wheels must be used only for specified applica

-

tions. 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 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.

6. 

Do not use worn down wheels from larger 
power tools.

 A wheel intended for larger power 

tool is not suitable for the higher speed of a 

smaller tool and may burst.

7. 

When using dual purpose wheels always use 
the correct guard for the application being 
performed.

 Failure to use the correct guard may 

not provide the desired level of guarding, which 

could lead to serious injury.

Additional safety warnings specific for cutting-off 

operations:

1. 

Do not “jam” the cut-off wheel or apply exces

-

sive 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 possibil-

ity 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 spin

-

ning wheel and the power tool directly at you.

3. 

When the wheel is binding or when interrupt-

ing a cut for any reason, switch off the power 

tool and hold it 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.

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 kick-
back.

 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, elec

-

trical wiring or objects that can cause kickback.

7. 

Do not attempt to do curved cutting.

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, which can lead to serious injury.

8. 

Before using a segmented diamond wheel, 
make sure that the diamond wheel has the 
peripheral gap between segments of 10 mm or 
less, only with a negative rake angle. 

Safety warnings specific for sanding operations:

1. 

Use proper sized sanding disc paper. Follow 
manufacturers recommendations, when 
selecting sanding paper.

 Larger sanding paper 

extending too far beyond the sanding pad pres

-

ents a laceration hazard and may cause snagging, 

tearing of the disc or kickback.

Safety warnings specific 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 specified 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 fiberglass-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 X-LOCK holder. 
Damage to the 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 specified surface of the wheel to per

-

form the grinding.

7. 

Do not leave the tool running. Operate the tool 
only when hand-held.
