2.3.1
DO NOT attempt to clean or service machine while it is running.
Rotating parts can cause severe injury.
2.3.2
DO NOT crank a flooded engine with the spark plug removed on
gasoline-powered engines. Fuel trapped in the cylinder will squirt out
the spark plug opening.
2.3.3
DO NOT test for spark on gasoline-powered engines, if engine is
flooded or the smell of gasoline is present. A stray spark could ignite
fumes.
2.3.4
DO NOT use gasoline or other types of fuels or flammable solvents to
clean parts, especially in enclosed areas. Fumes from fuels and
solvents can become explosive.
2.3.5
ALWAYS handle blades carefully. The blades can develop sharp
edges which can cause serious cuts.
2.3.6
ALWAYS keep area around muffler free of debris such as leaves,
paper, cartons, etc. A hot muffler could ignite them, starting a fire.
2.3.7
ALWAYS replace worn or damaged components with spare parts
designed and recommended by Wacker.

The Riding Trowel features a seat with an integrated “operator
presence” system, which works in conjunction with a throttle mounted
switch. This system allows the engine to remain running (idling) with
no operator seated in the seat, as long as the throttle is not depressed.
This system meets all safety requirements and eliminates the need for
a foot-operated “kill switch”.
To familiarize a new operator with the Riding Trowel the following
steps should be taken:
wc_tx000093gb.fm
4.1.1
With the operator in the seat, show him or her the functions of the
control arms (c) and how to start the machine.
4.1.2
Have the operator practice steering the trowel. A hard concrete slab
slightly wetted with water is an ideal place for an operator to practice
with the machine. For this practice, pitch the blades up approximately
¼" 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° turns. The best control is achieved at full rpm.

a foot-operated “kill switch”.
To familiarize a new operator with the Riding Trowel the following
steps should be taken:
wc_tx000093gb.fm
4.2.1
With the operator in the seat, show him or her the functions of the
control arms (c) and how to start the machine.
4.2.2
Have the operator practice steering the trowel. A hard concrete slab
slightly wetted with water is an ideal place for an operator to practice
with the machine. For this practice, pitch the blades up approximately
¼" 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° turns. The best control is achieved at full rpm.

Rotation of the gearboxes will differ depending on which side of the
trowel the gearbox is located. Gearboxes located on the Right-hand
side of the trowel rotate counterclockwise or left-hand rotation when
viewed from the top. Gearboxes on the Left-hand side of the trowel
rotate clockwise or right-hand rotation. The blade rotors rotate IN
under the operator.
Blade rotors require timing so they will not interfere with each other
during operation.
Anytime the drive line or gearboxes are removed, timing may be
required. When properly timed, the blades should be positioned 45
degrees off of each other.

7.1.11
Attach each pivot bracket (i) with bolt (g) and nut (h).
7.1.12
Attach each steering lever with bolts (d, e) and spacers (f).
7.1.13
Adjust the steering handle pitch by loosening the nuts on the left/right
pivot links (q) and turning the adjustable links to increase or decrease
the handle pitch. The optimum pitch has been determined to be 5°
forward for most operators. A rafter angle gauge works well for
determining pitch. After setting desired pitch, torque nuts to 75 Nm (55
ft.lbs.).
7.1.14
Adjust the steering handle force and travel. Locate the forward/reverse
steering pivots (r) and the left/right pivot links (q). The attaching bolts
(s) and nuts (t) for these links can be moved to the front or rear
mounting holes. The hole towards the front of the machine will give the
operator a lighter steering handle feel but does require a bit more
handle travel for steering responsiveness. Placing the link in the rear
hole will increase the steering response somewhat but also increases
the amount of effort needed to move the steering handles. The links
also need to be moved in the upper pivot bracket (i) so the adjustable
link remains in a vertical position. Torque the nuts (t) to 75 Nm (55
ft.lbs.).

Electric Steer Error Code Diagnostics and Troubleshooting
See Graphic: wc_gr002279
When an error code is displayed via the flashing red warning lamp the
following steps should always be followed.
wc_tx000096gb.fm
7.8.1
Turn ignition switch OFF. Turn ignition switch back ON and check the
steering system functionality on all 3 circuits; right, side, and left. If
error warning lamp is no longer flashing and the system is functional,
no further action is required. If the lamp is still flashing, turn ignition
switch OFF and proceed to next step.
7.8.2
Use a digital volt/ohm meter and check the static battery voltage.
Voltage must be over 11 VDC. If the system voltage is 11 VDC or
more, check the 70 amp Maxi-Fuse for the steering control system
actuators. It is located under the seat pedestal above the relays and
ignition module cover. If the voltage is under 11 volts, test and repair
the charging system.
7.8.3
Turn ignition switch ON and allow system to initialize. Record the error
code being displayed by the flashing red warning lamp. The lamp will
show a long pause followed by 1 to 4 quick flashes, a short pause, 1
to 3 quick flashes, a short pause and 1 to 5 quick flashes. The
sequence will repeat as long as there is a fault present. If the green
lamp is flashing, the machine is in an “open loop” and this indicates a
load pin fault. When the system goes into “open loop”, the load pins no
longer provide feedback to the control board. The actuators are driven
in or out by the joystick only. When the joystick is moved the actuator
will move. The actuator does not return to the center position when the
joystick is released, as it does in “closed loop”. The joystick must be
used to move the actuator in the opposite direction.
7.8.4
Use the following troubleshooting guide to diagnose and repair the
failure.

Error Code 111 - Right Actuator Fault
7.9.1
Perform a visual inspection of the right actuator wire connections and
associated wiring. Inspect the mechanical parts to make sure no
hardware is loose and the jam nut is tight. If no faults are found
proceed to next step.
7.9.2
Turn ignition switch ON. Watch for movement of the right actuator
when the right joystick is moved to full forward and full reverse
positions. If there is little or erratic movement, turn ignition switch OFF.
Inspect that the jam nut at the bottom of the actuator cylinder is tight.
If the nut is loose it will have erratic or no movement as the drive barrel
will spin on the threaded rod end. See section Removal and Installation
of Electric Steering Actuators to replace actuator. If the jam nut is tight,
proceed to next step.
7.9.3
Disconnect the wire connector labeled M1 at the actuator. Use a digital
volt/ohm meter, check actuator motor resistance at the motor wire
connector. The motor resistance should be 0.2-1.0 ohms. If the
reading is higher than 1.0 ohms, replace the right actuator motor. If
there was no actuator movement, the jam nut was tight, and the motor
resistance is correct, proceed to next step.
7.9.4
Be certain the ignition switch is turned OFF. Connect the black lead of
the digital volt/ohm meter to the battery ground on the right rear frame
of the machine. Set the meter to the DC voltage scale and check
terminals of the wiring harness side of the M1 connector. The orange
and the black wires should read battery voltage with the ignition switch
OFF. Turn ignition switch ON and check the wires again. With the right
joystick in the centered position, the meter should read 0 volts.
Connect to the orange wire and move the right joystick to the full
forward, back to center and to full reverse positions. The meter should
read battery voltage in one direction but read 0 VDC in the center and
opposite positions. Perform the same test on the black wire, readings
should be reversed. Proceed to next step.

Threadlockers and Sealants
Threadlockers and Sealants
Threadlocking adhesives and sealants are specified throughout this
manual by a notation of “S” plus a number (S#) and should be used
where indicated. Threadlocking compounds normally break down at
temperatures above 175°C (350°F). If a screw or bolt is hard to
remove, heat it using a small propane torch to break down the sealant.
When applying sealants, follow instructions on container. The sealants
listed below are recommended for use on Wacker equipment.
