Grinding Tips Operating Grinder
The grinder is a safe tool when used properly. In
addition to the safety instructions in this manual,
the most important safety consideration is to use
common sense at all times. What may be okay in
one situation, may not be safe in another.
Read and understand the following state-
ments to protect yourself before grinding:
• Make sure all guards are in place.
• Stand to the side of the grinder when you turn
it ON and allow it to run for one full minute
before beginning any grinding procedure.
• Make sure there are no loose mounting bolts
and that you have performed the “Test Run”
instructions in this manual.
• Remember that grinding often produces
sparks. DO NOT allow anyone to stand in the
path of the sparks. DO NOT grind near poten-
tially flammable materials, such as flammable
liquids or gases, paper or cloth.
• Wear the proper protective clothing.
Remember that particles flying off of a grind-
ing wheel will be traveling very fast—prepare
for this. Wear a face shield, a dust mask and
a leather apron.
• DO NOT lean into the workpiece in a manner
that may cause your hands to move into the
spinning wheel if the workpiece slips off.
• Concentrate on the task at ha
nd. STOP
grinding if there are distractions.
The grinder is designed for use with ferrous met-
als only. Grinding non-ferrous metals and wood
products will quickly load the grinding wheel sur-
face with particulate matter and ruin its abrasive
qualities. It can also cause the wheel to overheat
and possibly explode. Always grind on the sur-
faces shown in Figure
8.
After you have switched OFF the grinder,
DO NOT continue grinding and DO NOT
manually stop the grinding wheel with your
workpiece!
To grind with the grinding wheel:
1. Fill the water cup
3
/4 full with water.
2. With the machine plugged into power, stand
to the side of the grinding wheel, and turn the
grinder ON.
3. Allow the machine to run for one full minute to
ensure that the grinding wheels are safe for
use, then move to the front of the machine.
4. Grasp the workpiece tightly and properly sup-
port it on the work table.
5. Place the workpiece against the surface of
the wheel with moderate pressure, moving it
back and forth in a steady, even motion.
Note
: Using too much pressure will slow the
motor, may damage the wheel, and will over-
heat the workpiece. Using too little pressure
will prevent sufficient contact with the wheel.
