Operating tips
■ Do not turn the vibrator off while it is submerged in the concrete.
■ During use, insert the head quickly into the mix and then pull it out slowly. Rapid
removal is the main cause of poor concrete consolidation. For best results,
submerge head completely and try to establish a symmetrical pattern for
inserting and removing the head.
■ When moving around the job site, do not drag the vibrator head and flexshaft on
the ground.
■ Avoid touching forms and rebars when inserting the vibrator head into the mix.
This can transmit vibration to other areas of the mix which may already be
setting.
