4. Immerse the head for 5 to 10 seconds, until air stops
rising, then withdraw the head
slowly to let the
concrete fill the void left by the vibrator head.
5. Keep the flexible shaft as straight as possible and
DO NOT bend the flexible shaft sharply at any point.
Sharp bends can cause overheating, necessitating
early replacement of the flexible shaft.

NOTICE
To keep the vibrator head cool, make sure it is kept
completely below the concrete surface while vibrating.
CAUTION
If the shaft begins to helix (buckle) excessively during
operation,
STOP vibrating and investigate. This is an
indication of an overload condition.
NOTICE
The vibrator head is cooled by the concrete. Operation
of the vibrator head in the air (instead of concrete) for
longer than two minutes will cause overheating of the
bearings and premature head failure.
