Figure B shows the instruction label
housing. There are two alert modes.
1. Engaged Mode: When a stall situation presents itself, the
indicator light will come on and stay on as the motor cycles
on and off for a set period of time before the E-CLUTCH
Anti-Lock Control™ completely shuts the tool down. When
the unit is running in normal mode, there will be no light.
2. Problem Mode: A series of continual flashes of the
indicator light as the trigger is pulled, indicates that the
electronics are no longer functioning. The tool may still be
able to function without the benefit of E-CLUTCH Anti-Lock
Control™ but should be serviced as soon as possible.
