Introduction
Personal injury can result from hydraulic oil pressure and hot oil.
Hydraulic oil pressure can remain in the hydraulic system after the engine
has been stopped. Serious injury can be caused if this pressure is not
released before any service is done on the hydraulic system.
Make sure all of the work tools have been lowered to the ground, and the
oil is cool before removing any components or lines. Remove the oil fillercap only when the engine is stopped, and the filler cap is cool enough to
touch with your bare hand.
Hydraulic oil pressure can remain in the hydraulic systems after the

.
pressure is not released before any service is done on the hydraulic
systems. To prevent possible injury, refer to the section, Testing and
Adjusting, "Hydraulic System Pressure - Release" before any fitting,
hose or component is loosened, tightened, removed or adjusted.
When possible, the bucket or attachment must always be lowered to the
ground before service is started. When it is necessary for the boom to be
in the raised position while tests or adjustments are done, be sure that the
boom, stick and bucket or attachment have correct support.
The swing lock (if equipped) must be engaged before service is started.
Always move the machine to a location away from the travel of other
machines. Be sure that other personnel are not near the machine when the
engine is running and tests or adjustments are being made.
NOTICE
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting, and repair of
the product. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
containing fluids.
Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog"
for tools and supplies suitable to collect and contain fluids on Cat
products.
Dispose of all fluids according to local regulations and mandates .
ReferenceDisassembly and Assembly, UENR2321, "416F, 420F, and 430FBackhoe Loader Machine Systems"
This Special Instruction explains the installation of the new hoses for the backhoe. Do not begin the installation until you
have read the information that is contained in this instruction.
Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe
basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before
an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills,
and tools in order to perform these functions properly.
Safety precautions and warnings are provided in this instruction and on the product. If these hazard warnings are not
heeded, bodily injury or death could occur to you or to other persons.
This Special Instruction outlines the basic procedures that are required in order to install the auxiliary hydraulic lines onto
416F, 420F, and 430F Backhoe Loaders that are equipped with a standard stick assembly.
The auxiliary lines power work tools that require one-way flow or two-way flow. Work tools that require one-way flow
include hammers and compactors. Work tools that require two-way flow include thumbs and augers.
