H3368 Grinder/Sander Combo -13-
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 are in place.
• Stand to the side of the grinder when you turn
it on and allow it to run for 1 full minute before
EVERY use.
•Make sure that you have mounted your
grinder 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 flam-
mable 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, arm
guards, a hardhat 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 other people are distract-
ing you. STOP grinding/sanding if your mind
is on something else.
•DONOT grind on the side of the wheel.
Although side grinding is permissible for
some wheel types, the Model H3368 is not
designed for side grinding.
The grinder is designed for use with ferrous met-
als only. Non-ferrous metals and wood products
should be used on the sanding belt, as they will
quickly load the grinding wheel surface and ruin
its abrasive 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 make sure that the grinding wheel
is not going to fly apart and injure you, 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.
Tip: Using too much pressure will bog the
motor down and may damage the wheel.
Using too little pressure will make the work-
piece bounce around and you will not make
good contact with the wheel. Finding a bal-
ance with application pressure is part of
developing a good technique!
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.
