forces. Kickback forces can be controlled by the operator, if
proper precautions are taken.
• When wheel is binding, or when interrupting a cut for any
reason, release the trigger and hold the unit motionless
in the material until the wheel comes to a complete stop.
Never attempt to remove the unit from the work or pull the
unit backward while the wheel is in motion or kickback
may occur. Investigate and take corrective actions to elimi-
nate the cause of wheel binding.
• When restarting a cut-off tool in the workpiece, check
that the wheel is not engaged into the material. If wheel is
binding, it may walk up or kickback from the workpiece as the
tool is restarted.
• Support large panels to minimize the risk of wheel pinch-
ing and kickback. Large panels tend to sag under their own
weight. Support must be placed under the panel on both
sides, near the line of cut and near the edge of the panel.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chem-
icals 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 (CCA).
Your risk from these exposures varies, depending 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 equip-
ment, such as those dust masks that are specially designed to filter
out microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on
the skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust,
which may cause serious and permanent respiratory or other injury.
Always use NIOSH/OSHA approved respiratory protection appropri-
ate for the dust exposure. Direct particles away from face and
body.
CAUTION: Use extra care when working into a corner because
a sudden, sharp movement of the grinder may be experienced
when the wheel or other accessory contacts a secondary surface
or a surface edge.
CAUTION: Wear appropriate personal hearing protection
during use. Under some conditions and duration of use, noise
from this product may contribute to hearing loss.
FEATURES
E-SWITCH PROTECTION™
The ON/OFF switch has a no-volt release function. In the event of
a power outage or other unexpected shut down, the switch needs
to be cycled (turned off and on) to restart tool.
CLUTCH (D28140, D28144, D28144N)
The torque limiting clutch reduces the maximum reaction torque
transmitted to the operator in case of jamming a cutting disc. This
feature also prevents the gearing and electric motor from stalling.
The torque limiting clutch has been factory set and cannot be
adjusted.
E-CLUTCH™
This unit is equipped with an E-Clutch™ (Electronic Clutch), which
in the event of a high-load or wheel pinch, the unit will shut off to
reduce the reaction torque to the user. The switch needs to be
cycled (turned off and on) to restart the tool.
POWER-OFF™ OVERLOAD PROTECTION
The power supply to the motor will be reduced in case of motor
overload. With continued motor overload, the tool will shut off. The
