Before Grinding 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 the following statements to protect your-
self before grinding:
• Make sure all guards and eye shields 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 EVERY use.
• Make sure that you have mounted your grind-
er securely 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
flammable liquids or gases.
• Wear the proper protective clothing.
Remember that particles flying off of a grind-
ing wheel will be traveling very fast—prepare
for this. Wear safety glasses or a face shield,
a dust mask, earplugs, a leather apron, and
heavy leather boots.
• 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 hand. STOP
grinding/sanding if there are distractions.
• DO NOT grind on the side of the wheel.
Although side grinding is permissible for
some wheel types, the Model H7760 is not
designed for side grinding.
The grinder is designed for use with hard metals
only. Soft metals and wood products should only
be used on the sanding belt, as they will quickly
load the grinding wheel surface and ruin its abra-
sive qualities.
To grind with the grinding wheel:
1. Fill the coolant tray 3 ⁄
4
full with water.
2. With the machine plugged into power, stand
to the side of the grinding wheel, and move
the red switch to the
ON position.
3. Allow the machine to run for at least 1 full
minute to ensure that the grinding wheel is
safe for use, then move to the front of the
machine.
4. Grasp the workpiece tightly and properly sup-
port it on the tool rest.
5. Place the workpiece against the front 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 and may damage the wheel. Using
too little pressure will make the workpiece
bounce around and you will not make good
contact with the wheel.
6. Regularly dip the workpiece into the coolant
tray to cool it off.
7. When you are ready to stop the grinder,
move the red switch to the OFF position. At
this point, DO NOT continue grinding and
DO NOT manually stop the grinding wheel
with your workpiece!
Grinding accidents can cause serious injury
or death! Protect yourself by reading and
following all preceding safety information in
this manual before grinding.
