a) 

Maintain a firm grip on the power tool and 

position your body and arm to allow you to 
resist kickback forces. Always use auxiliary 
handle, if provided, for maximum control over 
kickback or torque reaction during start-up.

 

The operator can control torque reactions or 
kickback forces, if proper precautions are taken. 
b) 

Never place your hand near the rotating 

accessory.

 Accessory may kickback over your 

hand. 
c) 

Do not position your body in the area where 

power tool will move if kickback occurs.

 

Kickback will propel the tool in direction opposite 
to the wheel’s movement at the point of snagging. 
d) 

Use special care when working corners, 

sharp edges etc. Avoid bouncing and snagging 
the accessory.

 Corners, sharp edges or bouncing 

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: 

a) 

Use only wheel types that are recommended 

for your power tool. 

b) 

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. 
c) 

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: 

16. 

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

17. 

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. 

18. 

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

19. 

Watch out for flying sparks. Hold the tool so 
that sparks fly away from you and other 
persons or flammable materials. 

20. 

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

21. 

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

22. 

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

 

23. 

Check that the workpiece is properly 
supported. 

24. 

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. 

25. 

Do not use the tool on any materials 
containing asbestos. 

26. 

Always be sure you have a firm footing. Be 
sure no one is below when using the tool in 
high locations. 

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.
