switch to ON.

Switching the Unit Off: Set mode selector switch to OFF.

POWER TOOL ACTIVATION MODE

POWER BROKER

POWER ALLOCATION FEATURE The Power Broker feature allows optimal allocation of the power available between the vacuum cleaner and power tool on either 15- Amp or 20-Amp circuits:

Before connecting power tool, set POWER BROKER™ dial as follows:

1.Get tool amp rating from tool dataplate

2.Subtract tool amp rating from building circuit’s amp rating

3.Set dial to the difference.

Notes:

The building's circuit breaker can trip if the combination of power tool amp rating and the dial setting exceed the building circuit's amp rating.

The dial should be set at 11 amps unless the building circuit's amp rating minus the power tool amp rating setting is less than 11 amps.
