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 - operator’s 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).
