GENERAL SAFETY ESSENTIALS
Accessory Applications
The excavator has been primarily designed for moving earth
with a bucket. For use as a grapple or for other object handling,
contact
DOOSAN for proper installation and application.
Lifting-work applications (unless restricted or prohibited by local
regulations) are permitted in approved lift configuration, to rated
capacity only, with no side-loading. DO NOT use the machine for
activities for which it was not intended. DO NOT use the bucket
for lifting work, unless lift slings are used in the approved
configuration.
Use of an accessory hydraulic hammer (breaker), work in rough
terrain, demolition applications or other hazardous operation
may require installation of additional protective structures to
safeguard the operator.
Lifting Capacity Rating Configuration
Lifting capacity ratings that are printed at the end of this safety
section are based on the machine being level, on a firm
supporting surface, with hooks and slings attached in approved
configuration. Loads must be balanced and supported evenly.
Use tag lines to keep the load steady if wind conditions and
large surface area are a problem. Work crew hand signals,
individual tasks and safe procedures should all be universally
understood before the lift is made.
IMPORTANT
Before using the excavator to make lifts check municipal
and regional regulations or statutes that could apply.
Governing ordinances may require that all heavy lifting be
done with single purpose equipment specifically designed
for making lifts, or other local restrictions may apply.
Making heavy lifts with a general purpose excavator that
can be used for digging, loading, grading or other work may
be expressly forbidden by a regional injunction or other
legal prohibition. Always follow all the other instructions,
guidelines and restrictions for Safe Lifting in the Operation
and Maintenance Manuals.

SP000014
LOCATION OF SAFETY LABELS
Location of safety labels (decals) can vary from unit to unit.
Refer to appropriate Operation and Maintenance Manual, and
parts manual for your unit.
Always replace damaged or faded decals.

SP000014Track Excavator Safety

SUMMARY OF SAFETY
PRECAUTIONS FOR LIFTING
IN DIGGING MODE
To lift safely while in Digging Mode, the following items must be
evaluated by the operator and the work site crew.
• Condition of ground support.
• Excavator configuration and attachments.
• Weight, lifting height and lifting radius.
• Safe rigging of the load.
• Proper handling of the suspended load.
Tag lines on opposite sides of the load can be very helpful in
keeping a suspended load secure, if they are anchored safely to
control points on the ground.
Always engage the "Digging Mode" control on the Instrument
Panel before using the excavator for lifting work.
DANGER!
Unsafe use of the excavator while making rated lifts could
cause serious, potentially fatal injuries or extensive damage
to the machine or nearby property. Do not let anyone
operate the machine unless they've been properly trained
and understand the information in the Operation and
Maintenance Manual.
WARNING!
NEVER wrap a tag line around your hands or body.
NEVER rely on tag lines or make rated lifts when wind gusts
are more than 48.3 km/h (30 MPH). Be prepared for any wind
gust when working with loads that have a large surface
area.
WARNING!
If you need more information or have any questions or
concerns about safe operating procedures or working the
excavator correctly in a particular application or in the
specific conditions of your individual operating
environment, please consult your local
DOOSAN
representative.

UNAUTHORIZED
MODIFICATIONS
Any modification made without authorization or written approval
from
DOOSAN can create a safety hazard, for which the
machine owner will be held responsible.
For safety's sake, replace all OEM parts with the correct
authorized or genuine
DOOSAN part. For example, not taking
the time to replace fasteners, bolts or nuts with the correct
replacement parts could lead to a condition where the safety of
critical assemblies are dangerously compromised.
GENERAL HAZARD
INFORMATION
Safety Rules
Only trained and authorized personnel can operate and maintain
the machine.
Follow all safety rules, precautions and instructions when
operating or performing maintenance on the machine.
Do not operate the machine if you are not feeling well, if you are
taking medication that makes you feel sleepy, if you have been
drinking, or if you are suffering from emotional problems. These
problems will interfere with your sense of judgment in
emergencies and may cause accidents.
When working with another operator or with a person on work
site traffic duty, be sure that all personnel know the nature of the
work and understand all hand signals that are to be used.
Always observe strictly any other rules related to safety.
Safety Features
Be sure that all guards and covers are installed in their proper
position. Have guards and covers repaired immediately if
damaged.
Be sure that you understand the method of use of safety
features such as safety lock lever and the seat belt, and use
them properly.
Never remove any safety features. Always keep them in good
operating condition.
Failure to use safety features according to the instructions in the
Operation and Maintenance Manual could result in serious
bodily injury.

Inside Operator's Cabin
When entering the operator's cabin, always remove all mud and
oil from the soles of your shoes. If you operate the travel pedal
with mud or oil stuck to your shoes, your foot may slip and this
may cause a serious accident.
After using the ashtray, make sure that any matches or
cigarettes are properly extinguished, and be sure to close the
ashtray. If the ashtray is left open, there is a danger of fire.
Do not stick suction pads to the window glass. Suction pads act
as a lens and may cause fire.
Do not leave lighters laying around the operator's cabin. If the
temperature inside the operator's cabin becomes high, there is a
danger that the lighter may explode.
Do not use cellular telephones inside the operator's cabin when
driving or operating the machine. There is a danger that this may
lead to an unexpected accident.
Never bring any dangerous objects such as flammable or
explosive items into the operator's cabin.
To ensure safety, do not use the radio or music headphones
when operating the machine. There is a danger that this may
lead to a serious accident.
When operating the machine, do not put your hands or head out
of the window.
When standing up from the operator's seat, always place safety
lock lever securely in the "LOCK" position. If you accidentally
touch the work equipment levers when they are not locked, the
machine may suddenly move and cause serious injury or
damage.
When leaving the machine, lower the work equipment
completely to the ground, set safety lock lever to the "LOCK"
position and shut down engine. Use the key to lock all the
equipment. Always remove key and take it with you.
Clothing and Personal Protective Items
Secure long hair, and avoid loose clothing and jewelry. These
items have the tendency to catch on controls or protrude into
parts and cause serious injury or death.
Do not wear oily clothes. They are flammable.
Full eye protection, a hard hat, safety shoes and gloves may be
required at the work site.
While working on the machine, never use inadequate tools. They
could break or slip, causing injury, or they may not adequately
perform intended functions.
