OPERATION
WARNING:
To prevent loss of control and possible serious personal injury, always operate the grinder with both hands, keep- ing one hand on the side handle.
Move the grinder continuously at a steady, consistent pace.
CAUTION:
If the grinder is held in one spot too long, it will gouge and cut grooves in the workpiece. If the grinder is held at too sharp an angle, it will also gouge the workpiece because of concentration of pressure on a small area.
Use just enough pressure to keep the grinder from chat- tering or bouncing.
NOTE: Heavy pressure will decrease the grinder’s speed and put a strain on the motor. Normally the weight of the tool alone is adequate for most grinding jobs. Use light pressure when grinding jagged edges or loose bolts where there is the potential for the grinder to snag on the metal edge.
