1.9 Starting

Before starting the operator must know the location and

function of all controls.

1. Pull choke knob (j

1

or j

2

) 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 on left and right foot pedals, turn engine switch

(m

1

or m

2

), 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 used on the CRT46 KHN trowel

has an oil alert switch designed to automatically stop

the engine if the oil level gets too low. If engine will not

start or stops during operation, check engine oil level.

The CRT46 ASO is equipped with an oil alert light (n)

to indicate a low oil condition. If the oil alert light

comes on, stop engine and add oil.

2. Open choke as engine warms up.

3. Allow engine to warm up before operating trowel.

CRT46 OPERATION 1A

1A-7

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 (CRT46 ASO only)

o - seat locking pin

p - seat adjust

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,

push 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).
