SPECIFIC SAFETY RULES
1.
Always use a DiamaPro Systems
dust shroud.
Shrouds protect opera-
tor from broken wheel fragments.
2.
Accessories must be rated for at
least the speed recommended on
the tool warning label.
Wheels and
other accessories running over rated
speed can fly apart and cause injury.
3.
Do not let the tool come in con-
tact with live wire.
Contact with a
“live” wire will make exposed metal
parts of the tool “live” and shock the
operator.
4.
Always use safety glasses or gog-
gles. Ordinary eye or sun glasses
are NOT safety glasses.
5.
Check the wheel carefully for
cracks or damages before opera-
tion.
Replace cracked or damaged
wheel immediately. Run the tool (with
guard) at no load for about a minute,
holding tool away from others. If
wheel is flawed, it will likely separate
during this test.
6.
Only use with DiamaPro Systems
5” cup wheels and abrasives.
7
. Be careful not to damage the
spindle, the flange (especially the
installing surface) or the outer
flange.
Damage to these parts could
result in wheel breakage.
8.
NEVER use tool with wood cutting
blades or other saw blades.
Such
blades when used on a grinder fre-
quently kick and cause loss of control
leading to personal injury.
9.
Hold the tool firmly.
10
. Keep hands away from rotating
parts.
11.
Make sure cord is clear of wheel.
Do not wrap cord around your arm
or wrist. If control of tool is lost, cord
may become wrapped around you
and cause personal injury.
12.
Make sure the wheel is not con-
tacting the workpiece before the
switch is turned on.
13.
Before using the tool on an
actual workpiece, let it run for
a while.
Watch for vibration or
wobbling that could indicate poor
installation or a poorly balanced
wheel.
14.
Use the specified surface of the
wheel to perform the grinding.
15.
Watch out for flying sparks.
Hold
the tool so that sparks fly away from
you and other persons or flamma
-
ble materials.
16.
Do not leave the tool running.
Operate the tool only when hand-
held.
17.
Do not touch the workpiece im-
mediately after operation; it may
be extremely hot and could burn
your skin.
18.
ALWAYS wear proper apparel
including long sleeve shirts.
Leather gloves and shop aprons
to protect skin from contact with
hot grindings.
19.
Use of this tool to grind or
sand some products. Paints and
wood could expose user to dust
containing hazardous substanc-
es. Use appropriate respiratory
protection.
20.
Must use with DiamaPro Hepa
Filtered Dust Collector
DO NOT let comfort or familiarity with product (gained from repeated use)
replace strict adherence to grinder safety rules. If you use this tool unsafely or
incorrectly, you can suffer serious personal injury.
