TROWEL ARM ADJUSTMENT SCREW
The trowel arm adjustment screw is to be used for field adjustment of blade level, in the
event of a damaged trowel arm, to enable completion of the job. At the end of the job repairs
should be made to eliminate the damage. When assembling trowel blades to trowel arms, the
adjustment screw should NEVER protrude below the under-side surface of a trowel arm.
If the adjustment screw is not flush with the underside of the trowel arm, then this will
cause the power trowel to bounce and vibrate especially at high speed. This will also cause the
trowel blades to leave an uneven finish to the concrete due to the blades not being level to one
another.
Make certain that the adjusting screw is held firmly in place while tightening the bolt
which secures the blade to the trowel arm.
