Introducing the EXPERT™
The EXPERT™ is a versatile side-loading vehicle manufactured to the highest standards and designed
to collect residential and commercial refuse as well as recycling materials. Because of its drop-frame
configuration (see Figure 1-1), the EXPERT™ is perfect for manual or semi-automated waste/
recyclables collection. A loading height of only 5.5 inches above the chassis frame makes this
configuration safer, faster and easier to load. The hopper can be accessed from both curbside and
streetside, making collection in alleys and one-way streets quick and productive.
Figure 1-1 Drop-frame chassis
The EXPERT™ may be equipped with an automated Zero-Grab lifting arm, called “HELPING-HAND™”
arm, for efficient automated waste/recyclables collection. The HELPING-HAND™ arm can reach roller
carts that are up to 10 feet from the truck and can lift carts of up to 400 lbs when fully extended. The
HELPING-HAND™ arm is easy to operate with an electric over hydraulic joystick control, and the Zero-
Grab low swing-out makes it easy to collect refuse in narrow spaces. Also, on some units, the EXPERT™
is equipped with 2 automated lifting arms, one on each side of the truck, perfect for waste/recyclables
collection in alleys and one-way streets.
The EXPERT™ can be further customized to meet your needs. Many options are offered including:
glass compartment, organic bucket tipper, modified cab and many different split body configurations,
with optional single or split hydraulic chute. An optional cart tipper can be added and installed on
either side of the truck or on both sides for adequate semi-automated waste/recyclables collection.

Introduction 3
Many EXPERT™ units are of co-mingle type meaning their body is split in half or 50/50 to create
2 separate compartments for the collection of 2 different types of load. Other split body
configurations are available to cater to your specific collection needs.
The EXPERT™ has been developed based on years of experience and a wise choice of components.
Everything has been foreseen to achieve excellent reliability while keeping construction simple yet
robust.
Multiplexed System
Labrie has equipped your EXPERT™ unit with a CAN bus-based multiplexed system, which integrates
a monitor, a control panel, a joystick, and a set of electronic controllers. 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 monitor (see Figure 1-2), Labrie’s multiplexed system informs you of any malfunctions
that may occur during the operation of the truck. Various caution and warning messages can be
displayed on the monitor, depending on the seriousness of the situation. Yellow-highlighted
messages indicate that caution should be used while red-highlighted messages indicate a warning
situation that must be dealt with quickly.
Figure 1-2 Monitor
NOTE:Maintenance personnel as well as in-the-field technicians who encounter any problems with
the multiplexed system should refer to the Multiplex Diagnostic Manual (part# 153142) for
troubleshooting information and guidelines.

Versatility at its best (manual/semi-automated/fully automated waste collection)
Service and Maintenance on the EXPERT™
Maintenance on the EXPERT™ is of paramount importance to ensure long-lasting durability of all its
moving parts as well as optimum performance in heavy work. Maintenance has to be done on almost
every system involved in the operation of the EXPERT™, such as the hydraulic, electrical and
mechanical systems. Some parts are subjected to more wear and tear than others. Therefore, these
parts need regular maintenance and routine check-up to prevent signs of deterioration as soon as
possible.
NOTE:Any time you have a problem with a Labrie unit, you should contact your Labrie authorized
dealer first. They should be able to provide you with the proper help that you need, whether it
is for parts or technical service.
In this manual you will find the most common maintenance and inspection procedures required for
the EXPERT™.
Parts
Labrie refuse vehicle parts are offered exclusively through LabriePlus and LabriePlus authorized
dealers. The quality and reliability of Labrie parts are second to none in the industry.
Warning
Your EXPERT™ unit MUST BE COMPLETELY LUBRICATED before its first use. Refer to the lube
charts near the hopper on the curbside to know where the lubrication points are located on the
vehicle and how often the parts should be lubricated.
Initial lubrication carried out by Labrie Enviroquip Group is sufficient for production and transport
purposes ONLY.
With your safety in mind, we would like to remind you that ONLY QUALIFIED MECHANICS
should service the hydraulic, electrical, and pneumatic systems on your side loader. In addition, they
should also be fully knowledgeable in the operation of this unit. Please read the Operator Manual
prior to attempting any maintenance work on your EXPERT™ unit.

Introduction 5
EXPERT™ Basic Maintenance
EXPERT™ refuse bodies require routine maintenance to ensure product longevity as well as
dependability. Various components have specific needs. A detailed portion of these items is listed
below:
Packer Wear Shoes and Guides
Some of the most commonly overlooked wear items involve the packing system.
The packer wear strips and floor guides have a life which require proper maintenance. Improperly
maintained packers can result in, but are not limited to: holes worn in the floor liner and/or floor
itself, binding of the packing assembly due to uneven wear against the hopper side walls, etc.
For proper packer wear diagnosis and servicing, see page 127 and the following.
Lubrication
All moving parts require lubrication for continued operation, longevity and dependability.
The schedule for lubrication is based on an 800 can/5 day a week work schedule. Maintenance
intervals should be adjusted according to the truck’s route or duty cycle. Proper greasing ensures the
maximum life from the moving parts as it flushes out water and contaminants from the joint.
For proper lubrication specifications, see the Lubrication chapter on page 235.
Lifting Arm
Next to the packer, the lifting arm on an Automated Side Loader is the piece of equipment with the
most amount of movement throughout the course of a route. Due to this, the arm has the shortest
service interval and requires the most attention.
For the HELPING-HAND™ arm lubrication chart, see Figure 4-13. For maintenance of the arm, see
Lifting Arms on page 379.
Body
The body contains grease fittings for every operating cylinder as well as linkages.
Without proper lubrication and maintenance, these parts can become seized, galled, and/or break
resulting in equipment damage or injury.
For the EXPERT™ lubrication chart, see Figure 4-12. For maintenance of the body and its equipment
(such as cylinders, packer and tailgate), see General Maintenance on page 27.
Hydraulic Fluid and Filter
Hydraulic fluid is the life blood of the Labrie refuse body. Regular maintenance of the hydraulics will
ensure long, trouble-free life.
As directed in this manual and all service training, the hydraulic filter needs to be replaced after the
initial 50 hours of new truck operation and again every 6 months, or when the filter restriction gauge
is in the yellow.
The hydraulic fluid needs to be replaced once a year along with the suction screen being removed,
inspected, cleaned and/or replaced.
For more details on the hydraulic system of your truck, refer to the Hydraulic chapter on page 255.

6Introduction
Visual Inspection
Hardware
Hardware needs to be verified that it is present and tight. Loose or missing hardware can cause severe
equipment damage and/or unsafe operational conditions.
Adjustments
1. Cushions - Most of Labrie’s arm cylinders are cushioned. These cushions provide a smooth stop at
the end of the cylinder stroke, reducing impact and noise, which helps in the comfort of the drivers.
An improperly cushioned cylinder will cause damage to both the arm and cylinder. For cushion
adjustment procedures, see Cylinder Cushion Adjustment on page 390.
2. Proximity and Limit Switches - Proximity and limit switches are used to limit travel of moving parts
and/or to ensure conditions are safe for operation.
If these switches are not adjusted properly, damage to the equipment may occur as well as poor or
dangerous functionality.
For more information on proximity/limit switches, see Proximity and Limit Switches on page 200.
General Wear and Damage
1. Leaks - Verify that they are not any leaking hydraulic cylinders, hoses, tubes, valves, or pumps.
Leaks in the hydraulic system are an indicator of possibly overheating hydraulics, damage to a seal,
over-pressurization, or general wear. To avoid costly and premature replacement of parts, ensure all
leaks are addressed properly and timely.
2. Cracks - Ensure that they are not any cracks forming along the hopper floor edge, body, tailgate,
and/or arm/tipper/bucket if applicable. This is an indicator that something is worn, not adjusted
properly, or damaged.
3. Bushings/Bearings/Slides - Check for play in any bushing, bearing, or slide. This may require the
use of a pry bar or lifting equipment. For example, the lift pivot bushing on the HELPING-HAND™ will
need a forklift or lifting device to pick up on one side of the HELPING-HAND™ gripper assembly. While
lifting, look for any movement of the pivot separated from the arm slide. This is an indicator that the
bushing is in need of replacement.

including all applicable regulations, the Occupational Safety and Health Act (OSHA), and the
American National Standards Institute (ANSI).
