have a tendency to snag the rotating accessory 
and cause loss of control or kickback. 
e) 

Do not attach a saw chain woodcarving 

blade or toothed saw blade.

 Such blades create 

frequent kickback and loss of control. 

Safety Warnings Specific for Grinding and Abrasive 
Cutting-Off Operations: 

a) 

Use only wheel types that are recommended 

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. 
b) 

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. 
c) 

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, 
accidental contact with wheel and sparks that 
could ignite clothing. 
d) 

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. 
e) 

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. 
f) 

Do not use worn down wheels from larger 

power tools.

 Wheel intended for larger power tool 

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

Additional Safety Warnings Specific for Abrasive 
Cutting-Off Operations: 

a) 

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. 
b) 

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. 
c) 

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. 
d) 

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. 
e) 

Support panels or any oversized workpiece 

to minimize the risk of wheel pinching and 
kickback.

 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. 
f) 

Use extra caution when making a “pocket 

cut” into existing walls or other blind areas.

 

The protruding wheel may cut gas or water pipes, 
electrical wiring or objects that can cause kickback. 

Safety Warnings Specific for Sanding Operations: 

a) 

Do not use excessively oversized sanding 

disc paper. Follow manufacturers 
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. 

Safety Warnings Specific for Wire Brushing 
Operations: 

a) 

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. 
b) 

If the use of a guard is recommended for 

wire brushing, do not allow 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: 

16. 

When using depressed centre grinding 
wheels, be sure to use only fiberglass-
reinforced wheels. 

17. 

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. 

18. 

Be careful not to damage the spindle, the 
flange (especially the installing surface) or the 
lock nut. Damage to these parts could result 
in wheel breakage. 

19. 

Make sure the wheel is not contacting the 
workpiece before the switch is turned on. 

20. 

Before using the tool on an actual workpiece, 
let it run for a while. Watch for vibration or
