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 
wobbling that could indicate poor installation 
or a poorly balanced wheel. 

21. 

Use the specified surface of the wheel to 
perform the grinding. 

22. 

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

23. 

Do not touch the workpiece immediately after 
operation; it may be extremely hot and could 
burn your skin. 

24. 

Observe the instructions of the manufacturer 
for correct mounting and use of wheels. 
Handle and store wheels with care. 

25. 

Do not use separate reducing bushings or 
adaptors to adapt large hole abrasive wheels. 

26. 

Use only flanges specified for this tool. 

27. 

For tools intended to be fitted with threaded 
hole wheel, ensure that the thread in the 
wheel is long enough to accept the spindle 
length.
