OPERATION
GRINDING AND SANDING
See Figures 4 - 5.
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 not less than 11,000 RPM. |
The grinding wheel provided with the angle grinder is suit- |
able for grinding welds, preparing surfaces to be welded, |
grinding structural steel, and grinding stainless steel. |
Secure all work before beginning any operation. |
Secure small workpieces in a vise or clamp to a work- |

The key to efficient operation is by controlling the pres- |
sure and surface contact between the grinding wheel and |
workpiece. |
Flat surfaces are ground at an acute angle, normally |
between 5° and 15°. |
For maximum control, hold the angle grinder in front and |
away from you with both hands, keeping the grinding |
wheel clear of the workpiece. |
Start the angle grinder and let the motor and grinding |
wheel build up to full speed. |
Gradually lower angle grinder until the grinding wheel |
contacts the workpiece. |
For best results keep the angle grinder tilted at an angle |
from 5° and 15° and continuously moving at a steady, |
consistent pace. |
Move the angle grinder back and forth or up and down |
over the work area. |
Keep the angle grinder moving so that an excessive |
amount of material is not removed from one area. |
If the angle grinder is held in one spot too long, it will |
gouge and cut grooves in the workpiece. |
If the angle 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 angle grinder from |
chattering or bouncing. Heavy pressure will decrease its |
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 angle grinder to |
snag on the metal edge. |
Lift the angle grinder away from the workpiece before |
turning the angle grinder off. |
NOTE: Only the grinding wheel is included with this tool.

WARNING:
Before performing any adjustment, make sure the tool is unplugged from the power supply and the switch is in the OFF ( O ) position. Failure to heed this warning could result in serious personal injury.
