WALK-BEHIND TROWELS
OWNER'S MANUAL

OPERATION (Floating)

When the slab has set sufficiently firm that the operator's footprint leaves a very slight
depression on the surface of the slab, it is ready for the floating operation.
Guiding the machine on the slab is very simple, a slight upward lift of the handle causes the
machine to travel to the left. Holding the handle in the neutral position, will slowly cause the
machine to spin in one spot. Slight downward pressure on the handle causes the machine to
travel to the right. Best results are obtained by covering approximately 4" on each turn. In other
words, let the machine move right or left, backwards or forwards, approximately 4" with each
revolution of the trowels. To fill a hole or cut down a hump, move the unit back and forth over
the problem area.
Under normal operating conditions the machine should cover as much as 1000 sq. ft. in about
15 minutes. It is recommended that a slight tension on the trowel control cable, (but not a
definite tilt), during the floating operation will cause the machine to operate much smoother.
After the floated slab has set sufficiently, it is ready for the finishing operation.
CAUTION: Do not let the machine stand in one spot on the soft cement. Lift from the
slab when the floating operation is complete.

OPERATION (Finishing)

When starting the finishing operation, never set the trowels up over 1/4" pitch. This is important.
Guiding the machine on the slab is very simple, a slight upward lift of the handle causes the
machine to travel to the left. Holding the handle in the neutral position, will slowly cause the
machine to spin in one spot. Slight downward pressure on the handle causes the machine to
travel to the right. Best results are obtained by covering approximately 4" on each turn. In other
words, let the machine move right or left, backwards or forwards, approximately 4" with each
revolution of the trowels. To fill a hole or cut down a hump, move the unit back and forth over
the problem area.
After the first pass over the slab, the waiting time between operations is determined in the same
manner as if you were hand troweling. To repeat; the entire application and action of the
troweling machine in regard to getting on the slab, and the correct pitch of the trowels, is
determined in the same manner as would be used by a cement finisher when troweling by
hand.
