1Introduction
This manual contains information for the correct
maintenance of your 2R-III™ rear-loader garbage truck.
Maintenance personnel should read and understand
this information before doing repairs and maintenance
on the vehicle. For information on how to safely and
efficiently operate the 2R-III™, please refer to the
Operator’s Manual that is provided with your unit.
Introducing the 2R-III™
The main purpose of the 2R-III™ is to safely and
efficiently load, compact, transport and unload refuse.
The following describes how the unit performs those
tasks in the most basic terms. For a more detailed
description of the unit and its components, read the
complete 2R-III™ Maintenance Manual. Before going
further, you will need to become familiar with specific
terms that are used when referring to the 2R-III™
garbage truck.
Terms You Will Need to Know
Body’s main components are the hopper, the packer
panel, the tailgate, the pushout panel, and the carrier
panel. During collection, refuse is contained inside the
body.
Some trucks may be equipped with a cart tipper or a
push bar. If the latter is installed, a reeving cylinder or
a winch is provided.
The hopper is the area of the body where refuse is
dumped. The packer panel is the piece of equipment
that pushes refuse into the body. The pushout (or
ejection) panel is the piece of equipment that is used
to eject garbage at landfill sites. The tailgate is the rear
pivotal door that prevents refuse from exiting the body
during collection. At landfill, the tailgate is raised to
allow discharge of refuse.
Operating controls for the packer, carrier panel,
container handling system, and tipper (optional) are
located on the right-hand side of the tailgate.
Operating controls for the pushout panel and tailgate
are located on the left-hand side of the body, not far
from the cab.

Introduction 3
Waste Handling Process
The waste handling process in a 2R-III™ rear-loader garbage truck is a three-step process: 1. loading;
2. packing; 3. unloading. Take a look at the following illustrations. They will help you understand how
these steps relate to one another.
Loading
Refuse is first loaded into the hopper of the tailgate assembly. The carrier and packer panels, which
sweep up and pack the refuse from the hopper, will be in the “home” position.
Packing
When the operator starts the packing cycle, the carrier and packer panels move rearward over the
load.
Next, the carrier and packer panels automatically stop at the “interrupted cycle” position.

4 Introduction
The operator again activates the packing cycle. The carrier and packer panels move forward and
sweep the refuse from the hopper up into the body and pack it against the pushout panel. Having
completed a cycle, the carrier and packer panels are back into the “home” position and the hopper is
cleared for more refuse.
Also, during the packing cycle, considerable hydraulic pressure is applied to the cylinders which
control movement of the carrier and packer panels. This causes the refuse to be compacted tightly
allowing for a large carrying capacity.
Once the body is full, the 2R-III™ can be moved to the dumpsite for unloading.
Unloading
At the dumpsite, the unit is unloaded in two easy steps:
1. The tailgate is raised by the operator.
2. The pushout panel is moved to the rear of the body, pushing out the load.

Introduction 5
After unloading, the tailgate is lowered and “latched” to the body.
Container Handling Systems
The main purpose of a refuse body is to load, compact, transport and unload refuse. To assist in
loading refuse from containers, various container handling systems are available to be mounted on
LeachTM rear loaders.
A refuse container may be a mobile residential one (1) cubic yard container with casters or a ten (10)
cubic yard stationary commercial container. The equipment required to lift and empty these
containers will vary according to the container’s type and size.
The following are some handling systems that could be used:
A hydraulically operated container push bar for containers of 1 to 3 cubic yard capacity.
A drum winch or roof-mounted lifting cylinder for containers with capacities of four (4) or more
cubic yards.
Drum winches are rated at various pounds of pull. The 2R-III™ drum winch and lifting cylinder are
rated at 12,000 lbs.
NOTE:LeachTM bodies can be equipped with more than one container handling system.

8 Introduction
Container Handling Process
All LeachTM container handling systems have three (3) basic operation steps:
Attaching
The first step in container handling is to attach the container to the rear loader by securing it with the
latch arms of the container attachment.
Dumping
A container handling system is used to raise the container and empty its content into the hopper of
the rear loader.
Releasing
When the container is empty, it is lowered to the ground, the latch arms released and the truck is
moved forward.
