1.7 Description
The Riding Trowel is a modern, high production machine. Finishing rate will vary
depending on operator skill and job
conditions. The Riding Trowel has eight finishing blades. The standard-duty gearboxes are designed to provide
exceptional performance, low maintenance, and trouble-free use under some of the worst conditions.
All WACKER Riding Trowels are equipped with a safety kill switch and a low oil shutdown for added job safety and engine
protection. Operating time between fuel refills is approximately 2-1/2 to 3 hours with rotor speeds between 80 and 125
rpm.
Riding Trowels are the most technically advanced trowels on the market today. With proper maintenance and use, your
Riding Trowel will provide you with exceptional service.
1.8 Before Starting
Before starting trowel, check the following:
- oil level in engine
- oil level in trowel gearboxes
- fuel level
- condition of air filter
- condition of trowel arms and blades
Grease trowel arms daily.
1.9 Starting
Before starting, the operator must know the location and
function of all controls.
1. Pull choke knob (j) out to the closed position to start
a cold engine. The choke may not be needed if the
engine is warm or the air temperature is hot. In this
case, keep choke open by pushing knob in. Push
down left and right foot pedals, turn engine switch
(m), and hold it until engine starts.
CAUTION: Operating the starter motor for more
than 5 seconds can damage the motor. If engine fails
to start, release the switch and wait 10 seconds before
operating starter again.
Note: The engine is equipped with an oil alert light (n)
which will come on if engine oil level gets too low.
Continuing to run the engine with the oil alert light on
can damage the engine.
2. Open choke as engine warms up.
3. Allow engine to warm up before operating trowel.

1.10 Operating
To utilize your WACKER Riding Trowel to its fullest
capacity, the machine should be driven 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 about to be troweled. When the
machine reaches the end of the slab, make a 180 degree
U-turn, and repeat the straight line of direction to the other
end of the slab.
To familiarize a new operator with the Riding Trowel the
following steps should be taken:
1. Point out the location of all controls.
a - right pitch control
b - control level (left/right)
c - control lever (forward/reverse)
d - operators seat
e - left pitch control
f - fuel tank
g - left foot pedal (safety kill switch)
h - right foot pedal (throttle control)
i - battery/tool box
j - engine choke control
k - hourmeter
l - light switch
m -engine switch
n - oil alert light
o - seat locking pin
2. With the operator in the seat, show him the functions
of the control levers (b,c) and how to start the ma-
chine.
A hard concrete slab with water on the surface is an ideal
place for an operator to practice with the machine. For this
practice, pitch the blades up approximately 1/4" on the
leading edge. Start by making the machine hover in one
spot, and then practice driving the machine in a straight
line and making 180 degree turns. Best control is achieved
at full rpm.
CAUTION: DO NOT run the trowel during engine warm-
up or at an rpm that will cause the centrifugal clutch to
partially engage or slip. This will burn the clutch!
CAUTION: DO NOT use excessive pressure on the
control levers. Excessive pressure does not increase the
reaction time of the machine and can damage steering
controls.
1.11 Stopping
To stop trowel movement, return control levers (b,c) to
their neutral position and release pressure on right foot
pedal (h).
Note: On units equipped with the optional cruise control,
pull cruise lever up. This will release the right foot pedal
and reduce engine speed to disengage the clutch.
To stop engine, release left foot pedal
(g).
