I. INTRODUCTION
Thank you for purchasing the Pana-
sonic Angle Grinder. The powerful

great grinding performance.
This Angle Grinder is only to be used 
for grinding and cutting-off.

  There is an increased risk of elec-
tric shock if your body is earthed or 
grounded.
 3) Do not expose power tools to 
rain or wet conditions. 
  Water entering a power tool will in-
crease the risk of electric shock.
 4) Do not abuse the cord. Never 
use the cord for carrying, pulling 
or unplugging the power tool. 
Keep cord away from heat, oil, 
sharp edges or moving parts. 
  Damaged or entangled cords in-
crease the risk of electric shock.

fect the power tools operation. 
If damaged, have the power tool 
repaired before use.
  Many accidents are caused by 
poorly maintained power tools.
 6) Keep cutting tools sharp and 
clean.
  Properly maintained cutting tools 
with sharp cutting edges are less 
likely to bind and are easier to con-
trol.
 7) Use the power tool, accessories 
and tool bits etc. in accordance 
with these instructions and in 
the manner intended for the par-
ticular type of power tool, taking

ing of your power tool. Incorrect-
ly sized accessories cannot be ad-
equately guarded or controlled.
 6) The arbour size of wheels, flang-
es, backing pads or any other 
accessory must properly fit the 
spindle of the power tool. Acces-
sories with arbour holes that do not 
match the mounting hardware of 
the power tool will run out of bal-
ance, vibrate excessively and may 
cause loss of control.
 7) Do not use a damaged acces-
sory. Before each use inspect 
the accessory such as abrasive...

Kickback and Related Warnings
Kickback is a sudden reaction to a 
pinched or snagged rotating wheel, 
backing pad, brush or any other ac-
cessory. Pinching or snagging causes 
rapid stalling of the rotating accesso-
ry which in turn causes the uncon-
trolled power tool to be forced in the 
direction opposite of the accessory’s 
rotation at the point of the binding.
For example, if an abrasive wheel 
is snagged or pinched by the work-
piece, the edge...

Additional Safety Warnings 
Specific for Abrasive Cutting-
Off Operations:
  1) Do not “jam” the cut-off wheel 
or apply excessive pressure. Do 
not attempt to make an exces-
sive depth of cut. Overstressing 
the wheel increases the loading and 
susceptibility to twisting or binding of 
the wheel in the cut and the possibili-
ty of kickback or wheel breakage.
 2) 
Do not position your body in 
line with and behind the rotat-
ing wheel. When the wheel, at the 
point of operation, is moving away...
