INTENDED USE
This grinder is designed for professional grinding, sanding, wire
brushing, polishing or abrasive, cutting-off applications.
DO NOT use under wet conditions or in presence of flammable
liquids or gases.
This grinder is a professional power tool. DO NOT let children come
into contact with the tool. Supervision is required when inexperienced
operators use this tool.
ANTI-VIBRATION REAR HANDLE (FIG. 1)
The anti-vibration ring (J) reduces handle vibration and user fatigue in
extended use applications.
DUST EJECTION SYSTEM
The dust ejection system deflects debris that would be harmful to the
motor and allows cleaner air to pass over the motor.
TOUGHCORD™ SYSTEM
The TOUGHCORD™ system reduces the likelihood of cord pullout.
KEYLESS GUARD
This allows for tool free guard change and adjustment.
E-SWITCH PROTECTION™
(DWE4577, DWE4579, DWE4597 AND DWE4599)
The ON/OFF trigger switch has a no-volt release function. In the event
of a power outage or other unexpected shut down, the trigger switch
will need to be cycled (turned on and off) to restart tool.
CLUTCH
(DWE4577, DWE4579, DWE4597 AND DWE4599)
The torque limiting clutch reduces the maximum reaction torque
transmitted to the operator in the 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™
(DWE4577, DWE4579, DWE4597 AND DWE4599)
This unit is equipped with an E-Clutch™ (Electronic Clutch), which
in the event of a high-load or wheel pinch, the unit will be shut off to
reduce the reaction torque to the user. The switch needs to be cycled
(turned on and off) to restart tool.
POWER-OFF™ OVERLOAD PROTECTION
(DWE4577, DWE4579, DWE4597 AND DWE4599)
The power supply to the motor will be reduced in case of motor
overload. With continued motor overload, the tool will shut off. The
switch needs to be cycled (turned on and off) to restart tool. The tool
will power off each time the current load reaches the overload current
value (motor burn-up point). If continued overload shutdowns occur,
apply less force/weight on the tool until the tool will function without
the overload engaging.
COMPLETE ELECTRONIC CONTROL™
(DWE4577, DWE4579, DWE4597 AND DWE4599)
The internal electronic speed control offers consistent wheel speed
while using the tool.
ELECTRONIC SOFT START
(DWE4577, DWE4579, DWE4597 AND DWE4599)
This feature limits the initial start up momentum, allowing the speed to
build up gradually over a 1 second period.
EASY OFF WHEEL REMOVAL™ SYSTEM
(DWE4577, DWE4579, DWE4597 AND DWE4599)
This feature allows most accessories to be removed by hand without
the use of a tool.
