Operating Guidelines

Operating 

guidelines

Follow the guidelines below to use your Ride-On Trowel to its fullest capacity.

During the break-in period, run the engine at 50% of full throttle. See topic 
“Breaking In New Machines.”

Move the machine in the direction that the operator is facing. This will finish the 
widest possible area, while giving the operator an excellent view of the slab 
surface to be troweled.

When the machine reaches the end of the slab, make a 180° U-turn and repeat 
the straight line of direction to the other end of the slab. 

Alternatively, move the machine laterally (sideways) and then travel backward to 
the other end of the slab.

The best control of the Ride-On Trowel is achieved at full engine RPM.

Steps for new 

operators

Follow the steps below to familiarize a new operator with the Ride-On Trowel.

1. With the operator in the seat, show him or her the functions of the control arms 

and how to start the machine.

2. Have the operator practice steering the trowel. A hard concrete slab slightly 

wetted with water is an ideal surface on which to practice.
a. Pitch the blades up approximately 6.35 mm (0.25 in.) on the leading edge.
b. Start the engine, and begin by holding (“hovering”) the machine in place.
c. Practice moving the machine forward, backward, and laterally (sideways) in 

straight lines, then make a series of 180° turns.

NOTICE

Only experienced concrete finishers should operate the trowel.

Do not use excessive pressure on the control levers. Excessive pressure does 
not improve the response time of the machine and can damage the steering 
controls.

Attempting to use the trowel too early in the curing state of the concrete may 
result in an undesirable finish.
