Table 7.2
Push both the left and the right control levers forward (see fig. 7.2).
With your right foot, quickly depress the right foot pedal halfway. Notice that the ride-on power trowel
begins to move in a forward direction. Return both control levers to their neutral position to stop forward
movement, and then remove your right foot from the right foot pedal.
Practice holding the machine in one place as you increase blade speed. When about 75% of maximum blade
speed has been reached, the blade will be moving at proper finishing speed. The machine may be difficult to
keep in one place. Trying to keep the ride-on trowel stationary is good practice for the operator.
Practice maneuvering the ride-on trowel using the information listed in Table 7.2. Try to practice controlled
motions as if you were finishing a slab of concrete. Practice edging and covering a large area.
Try adjusting the pitch of the blades. This can be done with the ride-on trowel stopped or while the trowel is
moving, whichever feels comfortable. Test the operation of optional equipment like retardant spray and
lights.
Push both the left and right
control levers
backward and repeat steps 3 through 6 while substituting the word
reverse
for
forward
.
NOTICE: Trowel arms can be damaged by rough handling or by striking exposed plumbing or forms while in
operation. ALWAYS look out for objects which might cause damage to the trowel arms.
7.3 BLADE PICH
Sometimes it may be necessary to match blade pitch between the two sets of blades. There are some signs
that this may be necessary. For example, the differences in pitch could cause a noticeable difference in finish quality
between the two sets of blades or, the difference in blade pitch could make the machine difficult to control. This is
due to the surface area in contact with the concrete—the blade set with the greater contact area tends to stick to the
concrete more.
