4 Introduction
MINIMAX™ Basic Maintenance
MINIMAX™ 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:
1) Packing System
One of the most commonly overlooked wear items involves the packing system.
Many parts of the packing system have a life which requires 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.
2) Lubrication
Your MINIMAX™ unit MUST BE COMPLETELY LUBRICATED before its first use.
All moving parts require lubrication for continued operation, longevity and dependability.
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.
When greasing it is important to understand that providing the proper amount of grease is a delicate
balance between over greasing, which can result in seal damage as well as wasted lubricant. Only
pump enough grease until the air purges from the joint. Commonly, a “popping” sound can be heard
as the old grease begins to evacuate the seal. Equally important is to remove the excess grease from
the component you are maintaining. Leaving the excess grease will attract dirt and contaminants
which could work themselves into the joint causing potential future issues.
3) Lifting Arm
Next to the packer, the lifting arm on an Automated Side Loader is the piece of equipment with the
most amount of movements throughout the course of a route. Due to this, the arm has the shortest
service interval and requires the most attention.
For the H
ELPING-HAND™ arm lubrication chart, see Figure 4-10. For maintenance of the arm, see
Lifting Arm on page 191.
4) Body
The body contains grease fittings for every operating cylinder as well as all linkages.
Without proper lubrication and maintenance, these parts can become seized, galled, and/or break
resulting in equipment damage or injury.
For the M
INIMAX™ lubrication chart, see Figure 4-9. For maintenance of the body and its equipment
(such as cylinders, packer and tailgate), see General Maintenance on page 23.
5) Hydraulic Fluid and Filter
Hydraulic fluid is the lifeblood of the MINIMAX™ refuse body. Regular maintenance of the hydraulics
will ensure long, trouble-free life.
As directed in all service training, the hydraulic filter needs to be replaced after the initial 50 hours of
new truck operation and then 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.
