INSTALLING THE GRINDING WHEEL
Improper installation of the grinding wheel and clamp nut can cause damage to the grinding wheel and grinder.
Check to be sure the grinder is unplugged.
Install grinding wheels by turning the grinder upside-down so the spindle
faces up. Loosen the clamp nut with the wrench by turning counterclockwise.
Remove the clamp nut from the spindle revealing the disc flange, DO NOT
REMOVE THE DISC FLANGE. Place the grinding wheel on the spindle with
the depressed center facing up so the clamp nut will rest inside the
depressed center, and replace the clamp nut. The clamp nut must be placed
with the raised ridge facing out toward the grinding wheel. Tighten the clamp
nut with the wrench by turning clockwise. DO NOT OVERTIGHTEN.

All grinding wheels and accessories used with this grinder must be rated for 11,000 RPM or greater. Select grinding wheels and brushes
that are appropriate for the material for which they will be used. The grinding wheel that is included with the grinder is designed for grinding
welds, preparing surface to be weld, grinding structural steel and stainless steel. Use brushes for removing paint or rust from metal
surfaces, and use abrasive mop disks for sanding flat metal or wood surfaces.
GRINDER OPERATION
Lift the grinder off the work surface before starting and stopping the motor.
Applying too much pressure on the work surface while grinding can damage the grinder.
Always secure the work piece using clamps. Never use your hands to hold the work piece in place. An unsecured work piece
could cause serious injury.
When using the grinder, always grind flat surfaces by keeping the grinder at an angle of 5° -15°, so only the front of the grinding wheel
touches the surface. Grip the grinder firmly with one hand on the side handle and another hand on the motor housing. The arrow on the
front of the spindle housing indicates the direction the grinder wheel will spin.
Always select the appropriate grinding wheel for the job. The wheel provided with the grinder is suitable for grinding welds, stainless
steel, structural steel, or preparing surfaces to be welded. All grinding wheels purchased for use with this grinder should be rated for an
operating speed of at least 11,000 RPM. For best results, keep the grinder moving and apply just enough pressure to keep the grinder
from bouncing.
