Die/Straight Grinder Safety Rules
Always use proper guard with grinding
wheel, (Model 1214). A guard protects opera-
tor from broken wheel fragments. When using
grinding wheel attachments, the guard must
always be attached to the tool and positioned for
maximum safety, so the least amount of wheel
is exposed from the side the tool is being oper-
ated.
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.
Grinding wheels or any other accessory must
have a maximum safe operating speed greater
than the “no load RPM” marked on the tool’s
nameplate.
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tools may contact hidden wiring or
its own cord. Contact with a “live” wire will
make exposed metal parts of the tool “live” and
shock the operator.
Before using a grinder or installing a new
wheel, inspect the grinding wheel for chips
and cracks. Remove bad wheels immedi-
ately. Run the tool at no load for one minute,
holding the tool in the direction away from
people. Wheels with flaws will normally break
apart during this time.
Use clamps to support workpiece when-
ever practical. Never hold a small workpiece
in one hand and the tool in the other hand
while in use.
Inspect your workpiece before grinding.
Do not reach in the area of the spinning
accessory. The proximity of the spinning
accessory to your hand may not always be
obvious.
Always hold the tool firmly in your hands
during the start-up. The reaction torque of the
motor, as it accelerates to full speed, can cause
the tool to twist.
Let the accessory reach its full set speed
before contacting the workpiece. Never start
the tool while engaged in the material. The
accessory cutting edge may grab the material
causing loss of control of the tool.
Always disconnect the power cord from
the power source before making any adjust-
ments or attaching any accessories. You may
unexpectedly cause the tool to start, leading to
serious personal injury.
Do not leave a running tool unattended,
turn power off. Only when tool comes to a
complete stop it is safe to put it down.
Be aware of the switch location, when
placing the tool down or when picking the
tool up. You may accidentally activate the
switch.
Do not touch the accessory or collet after
use. After use the accessory and collet are too
hot to be touched by bare hands.
The direction of feed with the accessory
into the material when grinding, is very im-
portant. Always feed the accessory into the
material in the same direction as the cutting
edge is exiting from the material (which is
the same direction as the chips are thrown).
Feeding the tool in the wrong direction, causes
the cutting edge of the accessory to climb out of
the work and pull the tool in the direction of this
feed.
If the workpiece or accessory becomes
jammed or bogged down, turn the tool “OFF”
by the switch. Wait for all moving parts to
stop and unplug the tool, then work to free
the jammed material. If the switch to the tool
is left “ON” the tool could restart unexpectedly
causing serious personal injury.
Do not allow familiarity gained from fre-
quent use of your tool to become common-
place. Always remember that a careless frac-
tion of a second is sufficient to inflict severe
injury.
Do not alter or misuse tool. Any alteration
or modification is a misuse and may result in
serious personal injury.
Some dust created by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive
harm. Some examples of these chemicals
are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and
other masonry products, and
• Arsenic and chromium from chemically
treated lumber.
Your risk from these exposures varies, de-
pending on how often you do this type of work.
To reduce your exposure to these chemicals:
work in a well ventilated area, and work with
approved safety equipment, such as those dust
masks that are specially designed to filter out
microscopic particles.
