HOW TO GRIND
WARNING!
1. During operation, be sure to wear safety glasses and hearing protection.
2. Some dust created when using this grinder contains chemicals known to cause cancer,
birth defects or other reproductive harm. Some example of these chemicals are:
a. Lead based paints
b. Crystalline silica found in cement, bricks and other masonry products
c. Arsenic and chromium coming from pressure treated wood
d. Pesticides and other chemicals that could have been applied to the work area
3. An approved dust mask that protects the operator against these chemicals should be
worn at all times. These dust masks are designed to filter out microscopic particles.
DANGER!
1. If you accidentally drop the machine, do not use until checking that the machine and
grinding wheel are not cracked, deformed, or damaged.
2. Grinding wheels used on this tool should be rated at or above the no load rating marked
on this tool. Running grinding wheels over their rated speeds can fly apart and cause
injury.
CAUTION!
1. Do not press the lock pin while the wheel is rotating.
2. Do not turn the switch on with the lock pin pressed down.
HOW TO HANDLE THE GRINDER
1. It is not necessary to apply more force onto the machine than the force created by the
weight of the machine itself.
2. Applying excessive force may damage the grinding wheel and burn up the motor. Such
action may decrease the rotation speed which reduces the efficiency of dust suction,
because its power is driven by the spindle.
3. When used properly the unit should float on top of the brush ring, if excessive force is
applied the brush will be crushed and wear out.
4. Hold the tool with both hands while starting; the torque from the motor will cause the
tool to jerk.
5. The motor and vacuum system should be running at full speed before applying it to
the work surface.
6. When the grinding wheel first comes into contact with the work surface or when the
wheel is new, make contact slowly.
7. Keep moving the tool in a circular motion to prevent grooving in the work surface.
