Plug in your Oreck vacuum and use the power switch to turn on the motor. The power switch on an upright is usually at the top of the vacuum handle; on a canister model it is usually found near the center of the canister housing.
Slide or click the power switch into the "High" position to turn up the speed on a two-speed upright.
Press "High" on the speed switch below the power switch to select between the three highest speeds on the "Edge" series with variable power control. Each time you press "High," the motor will increase in speed.
Slide the speed control switch, which is located on the top of variable-speed Oreck canister vacuums, toward the right to increase the motor power setting.
