Description / Problem
Solution for Operator
No Issue
Tool is plugged in and a has power.
E-switch
Protection
(No-Volt)
The switch is in the ON position when
power is applied. The unit stayed off.
Cycle the switch to restart.
Kick Back Brake
A pinch or sudden deceleration of the
accessory has been sensed by the
tool and the kickback brake has been
activated.
Inspect accessory for damage from
pinch and replace if necessary.
Adjust work piece and tool position
as necessary and cycle switch to
restart.
Thermal
Protection
The tool has sensed that a critical
temperature of the motor or module
has been reached and it has shut
down to prevent further damage.
Ensure intake and exhaust vents
are not blocked by user or debris
during use. Adjust pressure to allow
for increased RPM.
Tool will restart with switch cycle
once cooled below the shutdown
threshold.
Feathering
Protection
The tool has sensed that the operator
has started/stopped the tool too
frequently and tool has shutdown to
prevent the critical components from
overheating during repeated rapid
start-up and braking.
Reduce feathering of switch. A
variable speed SKU should be used
if reduced speeds are required.
To reset/restart the tool after this
shutdown the tools power supply
must be cycled: unplug the tool and
plug back in, cycle switch to restart.
Constant Clutch
When the tool is overloaded and
slowed to a low speed threshold
torque is reduced to replicate the feel
of mechanical clutch and protect the
tool. If pressure is reduced allowing
the tool rpm to increase full torque will
return. If the tool is kept in Constant
Clutch mode for an extended period it
will result in a stall shutdown
Reduce pressure on the accessory
to allow the rpm to increase and
torque to return. Ensure the
accessory is not being bound-up.
Adjust accessory and workpiece as
needed.
Stall/Overload
Protection
The tool has sensed one of two
conditions and has shutdown:
-Accessory was pinched or bound
when tool is switched on. The
threshold is 0 rpm for <1 second.
-The accessory was stalled or bound
up during use for an extended time
period. See Constant Clutch.
Remove load from tool and cycle
switch to restart.
Problem Power
Line
The tool has sensed a poor-quality
power source such as a low quality
generator. The tool will shutdown to
prevent damage to the tool.
Try another power source, reduce
extension cord length or reduce
equipment load on the power
source.
