Operator's Manual

INTRODUCTION

For All Machine Users

This instruction manual describes the basic knowledge for the operation and inspection and maintenance procedures

applied when a super long front is mounted to the hydraulic excavator (main system).

This manual contains only the additional information related to the Super Long Front operation that differ from the

parts in the Operation Manual for the standard Hydraulic Excavator. Be sure to thoroughly read and understand the

Operator's manual for the standard machine (base machine) before operating this machine.

Contents described in this manual have priority.

Before starting to operate the machine, read this manual thoroughly and understand the contents.

Operate and service the machine safely and correctly.

Keep the operator's manual at the operating seat so that an operator can check the content anytime he/she needs. Any

operation that does not conform to contents of this manual will lead to serious accidents and/or system failure.

In addition, when you are replacing consumable parts, refer to the list of consumable parts before ordering them. Also,

always use Hitachi genuine parts. Using other than genuine parts will lead to serious accidents and/or system failure.

If you have any questions regarding the machine, provide the Model/type (model name) and the PIN (Product

Identification Number) of your machine.

Model/type and PIN are marked on the nameplate at the front side of the main frame.

Confirm the information beforehand and make a note in the blank after “PIN indication” on the first page of this

manual.

This manual is an important part of this machine. If you hand over your machine, surely attach this manual to the

machine for the new user. Any operation that does not conform to contents of this manual will lead to serious

accidents and/or system failure.

Due to modifications of the machine, contents of this manual and delivered machine may partially differ from each

other.

If you have any questions or find any part that concerns you, contact our branch office or our sales office nearest to

you.

This manual mainly applies SI (international) units for descriptions of amounts and quantities. In addition, it provides a

numeric value in traditional (MKS) or conventional unit as a reference value in parenthesis followed as needed.

Ex. 25.0 MPa (255 kgf/cm2)

Be sure to use fuel that complies with JIS K-2204, EN-590 or ASTM D-975 which contains 15 ppm or lower sulfur. Also

use fuel that complies with solid contamination level of class 18/16/13 of ISO4406-1999 (solid contamination includes

dust). If the fuel specifiedabove is not used, exhaust gas that exceeds the regulation values may be discharged, causing

serious problem on the engine. Consult your authorized dealer.

INTENDED USE

Intended Use

This machine is designed and intended to be used light to moderate excavating and slope finishing with bucket.

Risk assessment related to the specific application and working conditions of the machine may require additional safety

measures such as protective guards, safety glazing, filtration of cabin air, etc. to be installed, enabling the machine to be

operated safely under the specific conditions. Consult your authorized dealer for further information on possibilities to

adapt the machine accordingly.

This machine can be used for lifting applications that are within the lifting capacity of the machine. Use approved lifting

points and lifting devices and follow the instructions provided in this manual.

Local regulations and instructions must be respected when using the machine. Using this machine and its equipment for

operations other than those intended or approved by the manufacturer, are prohibited.

Modifications

No modification affecting the intended use or structural integrity and therefore safety of the machine should be made

without written approval of the manufacturer. Modifications which are not approved include the use of unauthorized

accessories, assemblies, parts or attachments, including but not limiting to those connected with a coupling device.

Any legal or natural person performing unapproved modifications to the machine assumes all liability directly or

indirectly related to the modification.

The manufacturer reserves the right to reject any warranty claim arising from or related to unapproved modifications.

Drive Machine Safely

Before driving the machine, always confirm that the travel

levers/pedals direction corresponds to the direction you

wish to drive.

Be sure to detour around any obstructions.

Avoid traveling over obstructions. Soil, fragments of rocks,

and/or metal pieces may scatter around the machine. Do

not allow personnel to stay around the machine while

traveling.

Driving on a slope may cause the machine to slip or

overturn, possibly resulting in serious injury or death.

Never attempt to ascend or descend 30 degrees or steeper

slopes.

Be sure to fasten the seat belt.

When driving up or down a slope, keep the bucket facing

the direction of travel, approximately 0.2 to 0.3 m (A) above

the ground. Expand the arm from vertical position on the

face of a slope.

If the machine starts to skid or becomes unstable,

immediately lower the bucket to the ground and stop.

Forbid swinging on a slope. Or it may cause the machine

to skid or turnover. If the direction must be changed, move

the machine to level ground, then, change the direction to

ensure safe operation.

Transport Safely

Take care the machine may turn over when loading or

unloading the machine onto or off of a truck or trailer.

Observe the related regulations and rules for safe

transportation.

Select an appropriate truck or trailer for the machine to

be transported.

Be sure to use a signal person.

Always follow the following precautions for loading or

unloading:

1) Select solid and level ground.

2) Always use a ramp or deck strong enough to support the

machine weight.

Loading docks must have an incline of less than 15

degrees.

3) Turn the auto-idle switch OFF.

4) Always select the slow speed mode with the travel mode

switch.

5) Never steer the machine while on the ramp. If the

traveling direction must be changed while the ramp,

unload the machine from the ramp, reposition the

machine on the ground, then try loading again.

6) The top end of the ramp where it meets the flatbed is a

sudden bump. Take care when traveling over it.

7) Place blocks in front of and behind the tires. Securely

hold the machine to the truck or trailer deck with wire

ropes.

Be sure to further follow the details described in the

TRANSPORTING section.

SAFETY

S-3

Avoid Rapid Machine Operation

Quick operation may cause the machine to tip over.

Especially never attempt to do quick travel or boom lowering

operation.

Avoid Work Other than Specified

This machine increases in weight of the counterweight and

has dedicated hydraulic system to operate the super long front

attachment.

Therefore, the standard front attachment can not be installed

on this machine.

Never install the front attachment of this machine to another

machine and never install front attachment of another

machine to this machine. Failure to do so may cause machine

turnover or damage, serious injury or death may result.

Be sure to use a bucket that has specified capacity, weight and

width. Otherwise, serious personal injury or death may result.

Take extra care when removing the stay pin. If the pin of

stay is removed, the stay will suddenly drop, your fingers

may be pinched by the stay.

Sign indicates a hazard of

being hit by the working

device of the machine. Keep

away from machine during

operation.
