Automatic Restart Protection

Helps prevent accidental startups after power
has been interrupted, e.g. the battery was re-
moved or discharged, or the tool stops due to
overload while the switch was in the on posi-
tion. To resume operation, turn on/off switch to
the off position, then restart the tool.

Constant Response Circuity

Helps maintain near constant RPMs between
no-load and load conditions.
Use this right angle die grinder only as intended. Unintended use may result
in personal injury and property damage.
This tool is intended for light: grinding, sanding, wire brushing, polishing, and carving, applica-
tions on metal, wood, plastic, stone, ceramic, leather and other materials. To perform any applica-
tion, mandrel mountable accessories, or accessories having shank diameter measuring 1/4" must
be used. All accessories used with this tool may not have a working diameter larger than two (2)
inches. Each accessory used with this tool must be carefully selected for the application, and may

Functional Description

Overload Protection

Helps protect tool from excessive heat that may
damage the motor. If all the LED indicator lights
flash yellow and the tool stops or slows during
operation, allow motor to cool for 30 seconds
by running no-load. If the overload protection
stops the tool repeatedly, excessive force is
causing the tool to overload. Stop excessive
force and readjust work piece to reduce force
applied.
