Introduction
The purpose of this manual is to introduce operators
to the operational procedures of the W
PENDULUM™ front-loader garbage truck. For
information regarding maintenance procedures, refer
to the related W
Manual.
Introducing the WITTKE
PENDULUM™
WITTKE PENDULUM™ units are front-load organics
collection vehicles used to pick up commercial
organics food waste. They can handle 3- to 6-yard
containers and collect 2 64- or 96-gallon carts at a
time. Once the body is full, all its content is unloaded
at a waste management landfill or other appropriate
site (e.g. transfer station, incinerator, recycling
station). These vehicles are designed to be operated by
only one person at a time, and they use a series of
hydraulic, pneumatic, mechanical, and electrical
systems to perform their work routine.
ITTKE PENDULUM™ Maintenance
ITTKE

W
ITTKE PENDULUM™ units are also equipped with the
multiplexed system designed to make the collection
process more efficient and the troubleshooting process
more orderly and manageable.
Figure 1-1

Page 12
2 Introduction
Product Overview
WITTKE PENDULUM™ units are fitted with a set of swing arms and forks to perform collection of
organics food waste.
Figure 1-2
Body’s main components are the hopper (see Figure 1-3), the pendulum packer (see Figure 1-3), the
tailgate (see Figure 1-4), and the swing arms and forks (see Figure 1-4).
The hopper is the area of the body where the food waste is dumped. The pendulum packer is the
piece of equipment that pushes the waste into the body. The tailgate is the rear door that prevents
food waste from exiting the body during collection. At a landfill, the tailgate is raised to enable the
discharge of the waste.

Controls and
Indicators
The WITTKE PENDULUM™ has a series of controls and
indicators that allow easier operation of the different
functions that come with the vehicle. These controls
and indicators are mainly located on the in-cab control
panel and on the dashboard.
Labrie’s Multiplexed System
Labrie has equipped your WITTKE PENDULUM™ unit
with a CAN bus-based multiplexed system, which
integrates a display monitor, a control panel, a joystick,
and a set of electronic modules. This whole system has
been designed to help you operate your unit in an
efficient and easy way. Labrie’s multiplexed system is
reliable and safe, and it requires less wiring harnesses
to operate. It can also monitor various function status
of the body and display warning and caution messages.
Through its display monitor (see Figure 3-1), Labrie’s
multiplexed system informs you of any malfunction
that may occur during use of the truck. Various caution
and warning messages can be displayed on the
monitor, depending on the seriousness of the
situation. Messages in yellow blocks indicate that
caution should be used; messages in red blocks
indicate a warning situation that must be dealt with
quickly.
Figure 3-1
Display monitor
Page 52
42 Controls and Indicators
Each time the operator turns the ignition key on, a complete bit test of the multiplexed system is
conducted. This test takes about 5 seconds to complete.
NOTE: A flashing green light on the monitor indicates that the display power is on. This light should
be blinking steadily at 2 Hz during normal operation. If it blinks at a faster rate, it is a sign of a
problem with the monitor. A flashing red light on the monitor is also a sign of a problem. Call
LabriePlus for support.
The logo of Labrie Enviroquip Group appears momentarily on the display monitor at the start of the
system (see Figure 3-2).
Figure 3-2
NOTE: If the Welcome Screen with the Labrie logo stays on continuously, there may be a
Labrie logo on the display monitor
communication problem between the monitor and the master control module. Report this
problem to the maintenance personnel.
NOTE: The display monitor works even if the engine is not started. All it needs is electrical power.
However, if you start the engine, the monitor will reboot to reflect the changes caused by the
starting of the truck.
Warning and Caution Messages
On the display monitor, messages in yellow blocks indicate that caution should be used and messages
in red blocks indicate a warning situation that must be dealt with quickly.

3. Position the front loader to approach the front of the container (see next illustration).
4. Adjust the arms and forks as required to securely engage the container.
5. Put the transmission to neutral and apply the parking brake (See Parking Brake on page 69).
6. Raise the container while adjusting the forks to ensure the container clears the cab guard and
canopy, and refuse does not spill before it reaches the hopper. Raise the container until the arms
rest on the rubber bump stops.
IMPORTANT: Do not tip the container much more than 45 degrees. The container may slip off the forks and fall
into the hopper.
NOTE: The forks may be cycled up and down in short movements to help empty the container.
7. Adjust the forks to a 45-degree angle to dump the content of the container into the hopper.
NOTE: While raising the arms and consequently the container, the operator should adjust the forks to
make sure the container clears the cab and canopy, and it does not prematurely spill or dump
refuse over the cab.
Page 93

packing refuse into the body.
Packing refuse can be done in two ways:
by pressing the Pack button — With the use of the Pack button on the control panel (see Pack
Push-Button (green) on page 66), you can control the pendulum packer’s sweep cycle. You can
however stop the packer by pressing the Stop button (red) and retract it by pressing the Return
button (yellow) at any point during the sweep cycle.
by using the Auto-Packing mode — Working in this mode, the pendulum packer’s sweep cycle
is fully automated and is triggered by the lowering of the arms. You can, however, stop the packer
by pressing the Stop button (red) or retract it by pressing the Return button (yellow) at any point
during the sweep cycle (see Auto-Packing Switch (optional) on page 62).
NOTE: Use the Auto-Packing mode when time is of the essence and you are secure in allowing the
W
ITTKE PENDULUM™ control of the pack cycle. This mode provides you with a hands-off
method of packing refuse while allowing you to focus on driving the front loader to the next
stop.
Packing Refuse Using the Pack Button
The pendulum packer should be cycled every time the content of a container is dumped into the
hopper.
To activate the packing cycle:
1. Turn on the hydraulic system (see Pump Switch on page 58).
NOTE: When the hopper door is open (see Figure 4-1), the hydraulic pump is disabled. This door
MUST therefore be closed properly in order for the hydraulic pump to be activated. The
Hopper Door Open indicator light on the control panel must also be green-lighted (see Hopper
Door Open Indicator Light on page 65).
2. Open the top door (see Top Door Switches (Roof Open/Roof Close) on page 64).
NOTE: A reinforced roof allows packing with the roof closed.
Page 95
Operating the WITTKE PENDULUM™ 85
IMPORTANT: The top door is only designed to prevent refuse from escaping the hopper during transport. It
should not be closed during packing, except if a reinforced roof is installed. Serious damage may
result.
3. Press the Pack button to actuate the pendulum packer. See Pack Push-Button (green) on page 66.
The packer should automatically complete a cycle then stop in its “home” position.
Packing Refuse Using the Auto-Packing Mode
To activate the packing cycle:
1. Turn on the hydraulic system (see Pump Switch on page 58).
2. Open the top door (see Top Door Switches (Roof Open/Roof Close) on page 64).
3. Turn on the Auto-Packing switch on the control panel (see Auto-Packing Switch (optional) on
page 62).
NOTE: Lowering the arms activates the Auto-Packing cycle when the corresponding switch is
activated (green-lighted).
4. Turn off the Auto-Packing switch when this feature is no longer needed.
Safety while Using the Packing System
Warning!
Danger!
Warning!
Always keep the warning lights and/or four-way flashers on when collecting refuse.
Never attempt to reach inside the hopper area when either the pendulum packer or the
arms are in motion. Severe injury or death may occur.

Unloading Refuse
Once the body of the WITTKE PENDULUM™ is full, drive the unit to the landfill or an appropriate area
for unloading purposes.
Preparing to Unload Refuse
To prepare your WITTKE PENDULUM™ unit for unloading:
1. Find an appropriate dump location. The truck must be on solid, level ground. Adequate
clearance must be provided to allow the tailgate to be fully opened and the refuse body to be fully
raised.
Caution!
Serious injury or mechanical damages could result if ground is unstable.

Unloading a WITTKE PENDULUM™ Unit
To unload refuse contained in a WITTKE PENDULUM™, do the following:
1. Press the Tailgate Up switch on the control panel (see Figure 3-17) and keep it pressed until the
tailgate is fully open.
NOTE: As soon as the tailgate is unlocked and opened, an in-cab buzzer and a back-up alarm will
sound. Also, during the upward movement of the tailgate, both the Tailgate Up switch and the
Tailgate Down switch flash red. The Tailgate Up switch will turn green when the tailgate
reaches its fully open position.
IMPORTANT: The tailgate must be fully open prior to unloading refuse.
2. Press the Body Up switch on the control panel (see Figure 3-17) and keep it pressed until the
body is fully raised.
3. Apply the foot brake and release the parking brake.
NOTE: The foot brake should be released while you unload, and allow the force of the moving load to
push the unit forward. Always be alert of what is in front of the truck.
4. Drive the unit slightly forward as the contained refuse is unloaded.
5. Set the parking brake.
6. Press the Body Down switch on the control panel (see Figure 3-17) and keep it pressed until the
body perfectly rests on the chassis.
