OPERATION
SWITCH ON AND OFF (Fig.5)
1. To turn the angle grinder “ON”,
push in the lock-off button (2)
and press the trigger switch (1).
2. To turn the tool “OFF,” release
the trigger switch.
WARNING! Hold the tool with
both hands while starting the tool, since torque from the motor can cause the
tool to twist. Start the tool before applying it to the workpiece and allow the tool
to come to full speed before contacting the tool to the workpiece. Lift the tool
from the workpiece before releasing the switch. Do not turn the switch “ON”
and “OFF” while the tool is under load, this will greatly decrease the tool life and
cause severe injury.
SELECTING GRINDING WHEELS
WARNING! Before using a grinding wheel, be certain that its maximum
safe operating speed is not exceeded by the nameplate speed of the grinder.
Do not exceed the recommended wheel diameter.
DISC GRINDING WHEELS
Grinding wheels should be carefully selected in order to use the grinder most
efficiently. Wheels vary in type of abrasive, bond, hardness, grit size and
structure. The correct type of wheel to use is determined by the job. Use disc
grinding wheels for fast grinding of structural steel, heavy weld beads, steel
casting, stainless steel and other ferrous metals.
GRINDING TIPS (Fig.6)
Efficient grinding is achieved
by controlling the pressure and
keeping the angle between wheel
and workpiece at 10
°
to 15
°
. If the
wheel is flat, 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.
