OPERATION
OPERATING THE GRINDER
See Figure 12.
Always carefully select and use grinding wheels that are recommended for the material to be ground. Make sure that the minimum operating speed of any accessory wheel selected is 6,500 r/min. or more. The grinding wheel provided with the grinder is suitable for grinding welds, preparing surfaces to be welded, grinding structural steel, and grinding stainless steel.
To operate the grinder:
Secure all work in a vise or clamp to a workbench.
DANGER:
Never use the grinder with the guard removed. It has been designed for use only with the guard installed. Attempting to use grinder with guard removed will result in loose particles being thrown against the operator resulting in serious personal injury.
Hold the grinder in front and away from you with both hands, keeping the grinding wheel clear of the workpiece.
Turn on the grinder and let the motor and grinding wheel build up to full speed.
Lower the grinder gradually until the grinding wheel contacts the workpiece.
Keep the grinder tilted at an angle between 5° and 15°.
WARNING:
To prevent loss of control and possible serious personal injury, always operate the grinder with both hands, keeping 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 chattering 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.
Lift the grinder away from the workpiece before turning off the grinder.
