30 General Maintenance
4. Check out for leaks on hydraulic hoses and tubes.
Tighten leaking connections and/or replace defective hoses.
5. Verify cylinder rods:
5 a. Make sure that cylinder rod ends are clear of debris.
5 b. Make sure that cylinder rods have no scratches that may cause the cylinder to leak oil.
Should you find oil leaks, the cylinder must be replaced immediately.
IMPORTANT: During the warranty period, do not attempt to change cylinder seals and packing.
6. Check the packer for vertical and horizontal movements. See Testing for Excessive Wear on
page 49 for correct procedure.
If the packer shows vertical or horizontal movement, wear pads need to be replaced. Extensive
wear on the hopper floor also suggests that sliding shoes require immediate replacement (see
Sliding Shoes on page 48).
7. Verify packer panel adjustment for knocking noises.
Knocking noises indicate that the Extend proximity switch requires adjustment (see Adjusting
Packer Extend Proximity Switch on page 79). Proper adjustment is necessary to prevent cylinders
from bottoming out under pressure.
8. Make sure that hydraulic cylinders are not leaking internally (resulting in insufficient packing
power). For more information, see Inspecting Hydraulic Cylinders on page 157.
Preparing Packer for Removal - Std. Units (Method A)
NOTE: There are 2 methods for preparing and removing the packer panel from a standard
A
UTOMIZER™ vehicle (Method A [taking packer out through the rear of the body] and Method
B [taking packer out through the hopper]). If you use Method A for the preparation of the
packer panel, you must then use Method A for the removal of the packer. The same goes for
Method B. The choice between both removal methods depends on numerous factors such as
the mechanics preferences, the condition of various packer parts and the type of lifting systems
available.
Follow these steps before proceeding with the removal of the packer panel:
1. Start the engine and engage the hydraulic pump.
2. Using the joystick, extend the automated arm to get better access to the hopper area.
Danger!
Secure the area around the path of the automated arm when performing maintenance or
repair.
