general information The MGX Vibrator has a double-insulated motor (no ground necessary) with advanced and user-friendly design. The motor is lightweight and durable with an aluminum motor case. The frontend closed-motor design prevents any invasion of mortar and foreign material from the front. Vibration-dampening handle grip reduces operator fatigue. Original cord protector gives flexibility to input cord for longer cord life.
general information NOTICE NOTICE Vibrator head spacing distance (D) is calculated by multiplying the vibrating head radius (R) (area of influence) by 1.5. When determining which head to choose it is important to access the application. Mainly what are the dimensions of the application. Select the vibrator head based on its radiating radius characteristics. Reference Table 4. Select the vibrating head that covers the largest possible area without excessive overkill.
components 1. ON/OFF Switch — Turns power on when pressed and off when released. 1 8 2 7 2. Power Cord — Connects to the power source. (120V or 220V depending on model). Make sure to check voltage on motor nameplate and connect to the appropriate power source. 3. Motor — 120V or 240V depending on model. 4. Flexible Shaft — Transmits rotary motion from the motor to the head. 3 6 5. Vibrator Head — Generates vibration via an eccentric rotator that consolidates the concrete by removing air pockets. 6.
operation operation 1. Connect the vibrator to the proper power source. 2. If an extension cord is necessary, refer to Table 5 for the correct type of extension cord to use. Table 5.
