Brake
When the switch is released the motor immediately turns
off and electronically brakes stopping the accessory quickly.
Kickback Brake™
When a severe pinch, stall, or bind-up event is sensed the
electronic brake engages with maximum force to quickly
stop the wheel, reduce the movement of the grinder, and
shut the grinder off. The switch needs to be cycled (turned
off and then on) to restart tool.
Constant Clutch™
When overloaded or stalled the motor torque is reduced. If
load is reduced the torque and RPM will increase. If the tool
is stalled for an extended amount of time it will shut-off and
require the switch to cycle to restart.
Variable Speed Dial (Fig. A)
WARNING: Regardless of the speed setting, the rated
speed of the accessory must be at least equal to the
maximum speed marked on the power tool.
The variable speed dial offers added tool control and
enables the tool to be used at optimum conditions to suit
the accessory and material.
