5. Thread the outer flange on the spindle
with the flat side of the flange facing up,
making sure that the opening in the wheel is
positioned around the raised portion of the
outer flange (FIG. 6).
6. Press the spindle-lock button to prevent
movement of the spindle.
7. Keep the spindle-lock button depressed;
tighten the threaded outer flange by
turning it clockwise with the wrench (FIG. 6).
WARNING:
Keep the guard between
you
and the wheel. Do not direct the guard
opening toward your body.

GRINDING OPERATION (FIG. 7)
WARNING:
Only use grinding wheels
for which the maximum safe operating speed
is rated at or above
13200RPM. 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 angle is too shallow the tool is
difficult to control. If the angle is too 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 pushed
forward.
WARNING:
Sparks are generated
when grinding metal. Take care that no
combustible material presented in the area of
flying
sparks.
