SVA-SERIES — OPERATION SVA Series Vibrator Motor Familiarization This VIBRATOR MOTOR is designed for the compaction of concrete by removal of air pockets and voids. The action of vibration is to set the particles in the fresh concrete in motion, thereby reducing the friction between the particles and giving the mixture the mobile quality of a thick fluid so gravity and the displacement of entrapped air will cause it to settle easily into place.
SVA-SERIES — MAINTENANCE MAINTENANCE Bronze Wear Bushing Replacement Refer to Figure 7 and the following steps for removal and replacement of the bronze wear bushing. CAUTION Before performing any maintenance on this unit, ALWAYS MAKE CERTAIN that the switch is in the "OFF" position and the power cord is disconnected from the power source. This is a universal motor and it will run at approximately its rated speed if the motor and its attached equipment are properly operated and maintained. 1.
