Grinding operation
WARNING!
Only use grinding wheels for which the maximum safe operating speed is rated at or
above 13200 RPM. Never use damaged or imbalanced grinding wheels. Do not exceed the
recommended wheel diameter. Grinding wheel type 27 is recommended for use on this
grinder
WARNING!
Firmly grasp the body of the tool and the side handle before starting.
Grinding tips
•
Use a clamp, vise or other practical means to hold your work, freeing both hands to control your tool.
Firmly grasp the body of tool and the side handle before starting and while the tool is in operation.
•
Efficient grinding is achieved by controlling
the pressure and keeping the angle between
the wheel and the workpiece at 10° to 15°
(fig 7). If the wheel is flat, the tool is difficult to
control. If the angle is to steep, the pressure is
concentrated on a small area, causing burning
to the work surface.
•
Move the angle grinder back and forth with
moderate pressure to avoid discoloring the
workpiece, overheating the workpiece and
creating ridges.
•
Never use a cut-off wheel to grind a work piece.
•
Always hold the tool properly so that sparks and grinding dust fly away from the body.
•
Start the tool before applying the accessory to workpiece and let the tool come to full speed before
contacting the workpiece. Lift the tool from the workpiece before turning the tool OFF.
•
When grinding with a new wheel, be certain to grind while pulling tool backwards until wheel
becomes rounded on its edge. New wheels have sharp corners which tend to “bite” or cut into
workpiece when pushing forward.
WARNING!
Sparks are generated when grinding metal. Take care that no combustible material
presented in the area of flying sparks.
