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: 

17. 

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

18. 

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. 

19. 

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. 

20. 

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

21. 

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. 

22. 

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

23. 

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

24. 

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

25. 

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

26. 

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

27. 

Use only flanges specified for this tool. 

28. 

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. 

29. 

Check that the workpiece is properly supported. 

30. 

Pay attention that the wheel continues to 
rotate after the tool is switched off. 

31. 

If working place is extremely hot and humid, 
or badly polluted by conductive dust, use a 
short-circuit breaker (30 mA) to assure 
operator safety. 

32. 

Do not use the tool on any materials 
containing asbestos. 

33. 

When use cut-off wheel, always work with the 
dust collecting wheel guard required by 
domestic regulation. 

34. 

Cutting discs must not be subjected to any 
lateral pressure. 

SAVE THESE INSTRUCTIONS. 

WARNING: 

DO NOT let comfort or familiarity with product 
(gained from repeated use) replace strict adherence 
to safety rules for the subject product. MISUSE or 
failure to follow the safety rules stated in this 
instruction manual may cause serious personal 
injury.
