the relative seriousness of, a hazard. All three indicate that a
safety risk is involved. Observe the precautions indicated
whenever a Safety Alert Symbol is present, no matter which
signal word appears next to it.
SAFETY ALERT SYMBOL
Be Prepared - Get to Know All Operating and Safety
Instructions.
This is a Safety Alert Symbol. Wherever it appears in this
manual or on safety decals on the machine, you must be
alert to the potential for personal injury or accidents.
Always observe safety precautions and follow
recommended procedures.

GENERAL
Safe Operation is Operator's
Responsibility
Only trained and authorized personnel should operate and
maintain the machine.
Follow all safety rules, regulations and instructions when
operating or performing maintenance on machine.
• Do not operate machine if you are under the influence of
drugs or alcohol. An operator who is taking prescription
drugs must get medical advice to determine if he or she
can safely operate a machine.
• When working with other personnel on a work site, be sure
that all personnel know nature of work and understand all
hand signals that are to be used.
• Be sure that all guards and shields are installed in their
proper location. Have guards and shields repaired or
replaced immediately if damaged.
• Be sure that you understand the use and maintenance of
all safety features such as safety lock lever and seat belt.
Use them properly.
• Never remove, modify or disable any safety features.
Always keep them in good operating condition.
• Always check for and know the location of underground
and overhead utility lines before excavating.
• Failure to use and maintain safety features according to
instructions in this manual, Safety Manual and Shop
Manual can result in death or serious injury.
Know Your Machine
Know how to operate your machine. Know the purpose of all
controls, gauges, signals, indicators and monitor displays. Know
the rated load capacity, speed range, braking and steering
characteristics, turning radius and operating clearances. Keep in
mind that rain, snow, ice, loose gravel, soft ground, slopes etc.,
can change operating capabilities of your machine.
Proper Work Tools and Attachments
Only use work tools and attachments that are recommended by
DOOSAN for use on DOOSAN machines. When installing and
using optional attachments, read instruction manual for
attachment, and general information related to attachments in
this manual. Because DOOSAN cannot anticipate, identify or
test all attachments that owners may want to install on their
machines, contact DOOSAN for written authorization and
9. SP002322
Page 9
Track Excavator Maintenance Safety
approval of attachments, and their compatibility with optional
kits.
Attachments and attachment control systems that are
compatible with the machine are required for safe and reliable
machine operation. Do not exceed maximum operating weight
(machine weight plus attachment) that is listed on ROPS
certification plate.
Make sure that all guards and shields are in place on machine
and on work tool. Depending on type or combination of work
equipment, there is a potential that work equipment could
interfere with the cabin or other parts of machine. Before using
unfamiliar work equipment, check if there is any potential of
interference, and operate with caution.
While you are performing any maintenance, testing, or
adjustments to attachments, stay clear of the following areas:
cutting edges, pinch points, and crushing surfaces.
Never use attachment as a work platform or manlift.
Contact your DOOSAN distributor about auxiliary hydraulic kits
for attachments installation. If you are in doubt about
compatibility of a particular attachment with a machine, consult
your DOOSAN distributor.
Pressurized Fluids
Pressurized air or fluids can cause debris and/or fluids to be
blown out. This could result in death or serious injury.
Immediately after operations are stopped, coolant, engine oil,
and hydraulic oil are at their highest temperatures and the
radiator and hydraulic tank are still under pressure. Always wait
for temperature to cool down. Follow specified procedures when
attempting to remove caps, drain oil or coolant, or replacing
filters. Always wait for temperature to cool down, and follow
specified procedures when performing these operations. Failure
to do so can result in death or serious injury.
When pressurized air and/or pressurized water is used for cleaning,
wear protective clothing, protective shoes, and eye protection. Eye
protection includes goggles or a protective face shield.
Pressure can be trapped in a hydraulic system and must be
relieved before maintenance is started.
Releasing trapped pressure can cause sudden machine
movement or attachment movement. Use caution if you
disconnect hydraulic lines or fittings.
High-pressure oil that is released can cause a hose to whip or oil
to spray. Fluid penetration can result in death or serious injury. If
fluid enters skin or eyes, get immediate medical attention from a
physician familiar with this injury.
Obey all local laws and regulations for disposal of liquids.
To prevent hot coolant from spraying out, stop engine and wait for
coolant to cool. Using gloves, slowly loosen cap to relieve pressure.

REMOVAL
1. Look at fuel level display (Figure 2) on instrument panel in
operator's cabin to see what it displays. The display is
divided into ten separated segments, each representing 10
percent of total fuel supply. Also, look at level gauge on
side of tank to estimate volume of fuel left in tank.
NOTE: If possible, operate excavator until available fuel
supply in tank has been run down as far as
possible.

approximately a 90° with respect to tracks. See Figure 3.
3. Lower bucket (or work tool) to ground.
4. Stop engine.
5. Set safety lever to "RELEASED" (UNLOCK) position.
6. Turn starter switch to "I" (ON) position.
