Foreword
Literature Information
This manual should be stored in the operator's
compartment in the literature holder or seat back
literature storage area.
This manual contains safety, operation, trans-portation,
lubrication and maintenance information.
Some photographs or illustrations in this publication
show details or attachments that can be different from
your lift truck. Guards and covers might have been
removed for illustrative purposes.
Continuing improvement and advancement of product
design might have caused changes to your lift trucks
which are not included in this publication.
Read, study and keep this manual with the lift truck.
Whenever a question arises regarding your lift truck, or
this publication, please consult your DOOSAN dealer for
the latest available information.
Safety
The Safety Section lists basic safety precautions. In
addition, this section identifies the text and locations of
warning signs and labels used on the lift truck. Read
and understand the basic precautions listed in the
Safety Section before operating or performing
lubrication, maintenance and repair on this lift truck.
Operator Restraint System (If Equipped)
This manual contains safety, operation and
maintenance information for the DOOSAN operator
restraint system. Read, study and keep it handy.
WARNING
Your DOOSAN truck comes equipped with an
operator restraint system. Should it become
necessary to replace the seat for any reason, it
should only be replaced with another DOOSAN
operator restraint system.
Photographs or illustrations guide the operator through
correct procedures of checking, operation and
maintenance of the DOOSAN operator restraint system.
SAFE and EFFICIENT OPERATION of a lift truck
depends to a great extent on the skill and alertness on
the part of the operator. To develop this skill the
operator should read and understand the Safe Driving
Practices contained in this manual.
Forklift trucks seldom tipover, but in the rare event they
do, the operator may be pinned to the ground by the lift
truck or the overhead guard. This could result in serious
injury or death.
Operator training and safety awareness is an effective
way to prevent accidents, but accidents can still happen.
The DOOSAN operator restraint system can minimize
injuries. The DOOSAN operator restraint system keeps
the operator substantially within the confines of the
operator’s compartment and the overhead guard.
This manual contains information necessary for Safe
Operation. Before operating a lift truck make sure that
the necessary instructions are available and understood.
Operation
The Operation Section is a reference for the new
operator and a refresher for the experienced one. This
section includes a discussion of gauges, switches, lift
truck controls, attachment controls, transportation and
towing information.
Photographs and illustrations guide the operator through
correct procedures of checking, starting, operating and
stopping the lift truck.
Operating techniques outlined in this publication are
basic. Skill and techniques develop as the operator
gains knowledge of the lift truck and its capabilities.

Information Section

Maintenance
The Maintenance Section is a guide to equipment care.
The illustrated, step-by-step instructions are grouped by
servicing intervals. Items without specific intervals are
listed under “When Required” topics. Items in the
“Maintenance Intervals” chart are referenced to detailed
instructions that follow.
Maintenance Intervals
Use the service hour meter to determine servicing
intervals. Calendar intervals shown (daily, weekly,
monthly, etc.) can be used instead of service hour meter
intervals if they provide more convenient servicing
schedules and approximate the indicated service hour
meter reading. Recommended service should always
be performed at the interval that occurs first.
Under extremely severe, dusty or wet operating
conditions, more frequent lubrication than is specified in
the “Maintenance Intervals” chart might be necessary.
Perform service on items at multiples of the original
requirement. For example, at “Every 500 Service Hours
or 3 Months”, also service those items listed under
“Every 250 Service Hours or Monthly” and “Every 10
Service Hours or Daily”.
Environment Management
Note that DOOSAN INFRACORE is ISO 14001 certified
which is harmonized with ISO 9001. Periodic
ENVIRONMENTAL AUDITS & ENVIRONMENTAL
PERFORMANCE EVALUATIONS have been made by
internal and external inspection entities. LIFE-CYCLE
ANALYSIS has also been made through out the total
product life. ENVIRONMENT MANAGEMENT
SYSTEM includes DESIGN FOR ENVIRONMENT from
the initial stage of the design.
ENVIRONMENT MANAGEMENT SYSTEM considers
environmental laws & regulations, reduction or
elimination of resource consumption as well as
environmental emission or pollution from industrial
activities, energy saving, environment-friendly product
design (lower noise, vibration, emission, smoke, heavy
metal free, ozone depleting substance free, etc.),
recycling, material cost reduction, and even
environmentally oriented education for the employee.

Never attempt adjustments while the lift truck is moving
or the engine is running unless otherwise specified.
Where there are attachment linkages, the clearance in
the linkage area will increase or decrease with
movement of the attachment.
Stay clear of all rotating and moving parts.
Keep objects away from moving fan blades.
They will throw or cut any object or tool that falls or is
pushed into them.
Do not use a kinked or frayed wire rope cable. Wear
gloves when handling the wire rope cable.
Retainer pins, when struck with force, can fly out and
injure nearby persons. Make sure the area is clear of
people when driving retainer pins.
Wear protective glasses when striking a retainer pin to
avoid injury to your eyes.
Chips or other debris can fly off objects when struck.
Make sure no one can be injured by flying debris before
striking any object.
Falling Objects Protective Structure(FOPS)
This is an attached guard located above the operator's
compartment and secured to the lift truck.
To avoid possible weakening of the Falling Objects
Protective Structure (FOPS), consult a DOOSAN dealer
before altering, by adding weight to, welding on, or
cutting or drilling holes into the structure.
The overhead guard is not intended to protect against
every possible impact. The overhead guard may not
protect against some objects penetrating into the
operator's station from the sides or ends of the lift truck.
The lift truck is equipped with an overhead guard and
FOPS as standard. If there is a possibility of overhead
objects falling through the guard, the guard must be
equipped with smaller holes or a Plexiglas cover.
Any altering done that is not specifically authorized by
DOOSAN invalidates DOOSAN's FOPS certification.
The protection offered by this FOPS will be impaired if it
has been subjected to structural damage.
Structural damage can be caused by an overturn
accident, by falling objects, etc.
Do not mount any item such as fire extinguishers, first
aid kits and lights by welding brackets to or drilling holes
in any FOPS structure. See your DOOSAN dealer for
mounting guidelines.

Batteries give off flammable fumes which can explode.
Do not smoke when observing the battery electrolyte
levels.
Electrolyte is an acid and can cause personal injury if it
contacts skin or eyes.
Always wear protective glasses when working with
batteries.
Fire or Explosion Prevention
All fuels, most lubricants and some coolant mixtures are
flammable.
Fuel leaked or spilled onto hot surfaces or electrical
components can cause a fire.
Do not smoke while refueling or in a refueling area.
Do not smoke in areas where batteries are charged, or
where flammable materials are stored.
Batteries in series can be located in separate
compartments.
When using jumper cables always connect positive(+)
cable to positive(+) terminal of battery connected to
starter solenoid and negative(-) cable from external
source to starter negative(-) terminal.
(If not equipped with starter negative(-) terminal, connect
to engine block.)
See the Operation Section of this manual for specific
starting instructions.
Clean and tighten all electrical connections. Check daily
for loose or frayed electrical wires. Have all loose or
frayed electrical wires tightened, repaired or replaced
before operation the lift truck.
Keep all fuels and lubricants stored in properly marked
containers and away from all unauthorized persons.
Store all oily rags or other flammable material in a
protective container, in a safe place.
Do not weld or flame cut on pipes or tubes that contain
flammable fluids. Clean them thoroughly with
nonflammable solvent before welding or flame cutting
on them.
Remove all flammable materials such as fuel, oil and
other debris before they accumulate on the lift truck.
Do not expose the lift truck to flames, burning brush, etc.,
if at all possible.
Shields, which protect hot exhaust components from oil
or fuel spray in the event of a line, tube or seal failure,
must be installed correctly.
Do not operate in areas where explosive gases exist or
are suspected.

Fire Extinguisher
Have a fire extinguisher-type BC and 1.5KG minimum
capacity-on rear overhead guard leg with latch and
know how to use it. Inspect and have it serviced as
recommended on its instruction plate.
Ether
Ether is poisonous and flammable.
Breathing ether vapors or repeated contact of ether with
skin can cause personal injury.
Use ether only in well-ventilated areas.
Do not smoke while changing ether cylinders.
Use ether with care to avoid fires.
Do not store replacement ether cylinders in living areas
or in the operator's compartment.
Do not store ether cylinders in direct sunlight or at
temperatures above 39°C (102°F).
Discard cylinders in a safe place. Do not puncture or
burn cylinders.
Keep ether cylinders out of the reach of unauthorized
personnel.
Lines, Tubes and Hoses
Do not bend or strike high pressure lines. Do not install
bent or damaged lines, tubes or hoses.
Repair any loose or damaged fuel and oil lines, tubes
and hoses. Leaks can cause fires. Contact your
DOOSAN dealer for repair or replacement.
Check lines, tubes and hoses carefully. Do not use your
bare hand to check for leaks. Use a board or cardboard
to check for leaks. See Fluid Penetration in the Safety
Section for more details. Tighten all connections to the
recommended torque. Replace if any of the following
conditions are found.
zEnd fittings damaged or leaking.
zOuter covering chafed or cut and wire reinforcing
exposed.
zOuter covering ballooning locally.
zEvidence of kinking or crushing of the flexible part of
hose.
zArmoring embedded in the outer cover.
zEnd fittings displaced.
Make sure that all clamps, guards and heat shields are
installed correctly to prevent vibration, rubbing against
other parts, and excessive heat during operation.
Tire Information
Explosions of air-inflated tires have resulted from heat-
induced gas combustion inside the tires. The heat,
generated by welding or heating rim components,
external fire, or excessive use of brakes can cause
gaseous combustion.
A tire explosion is much more violent than a blowout.
The explosion can propel the tire, rim and axle
components as far as 500 m (1500 ft) or more from the
lift truck. Both the force of the explosion and the flying
debris can cause personal injury or death, and property
damage.
Do not approach a warm tire closer than the outside of
the area represented by the shaded area in the above
drawing.

Safety Section
-17-
Dry nitrogen(N2) gas is recommended for inflation of
tires. If the tires were originally inflated with air, nitrogen
is still preferred for adjusting the pressure. Nitrogen
mixes properly with air.
Nitrogen inflated tires reduce the potential of a tire
explosion, because nitrogen does not support
combustion. Also, nitrogen helps prevent oxidation and
the resulting deterioration of rubber and corrosion of rim
components.
Proper nitrogen inflation equipment and training in its
use are necessary to avoid over-inflation. A tire blowout
or rim failure can result from improper or misused
equipment.
Stand behind the tread and use a self-attaching chuck
when inflation a tire.
Servicing, changing tires and rims can be dangerous
and should be done only by trained personnel using
proper tools and procedures. If correct procedures are
not followed while servicing tires and rims, the
assemblies could burst with explosive force and cause
serious personal injury or death. Follow carefully the
specific information provided by your tire or rim servicing
personnel or dealer.
Operator Restraint System (If
Equipped)
Warning Signs and Labels
Your DOOSAN lift truck has the following tipover
warning decals.
Make sure that you can read all safety signs. Clean or
replace these if you cannot read the words or see the
pictures. When cleaning the labels use a cloth, water
and soap. Do not use solvent, gasoline, etc. You must
replace a label if it is damaged, missing or cannot be
read. If a label is on a part that is replaced, make sure a
new label is installed on the replaced part. See you
DOOSAN Lift Truck dealer for new labels.
The most effective method of preventing serious injury
or death to yourself or others is to familiarize yourself
with the proper operation of the lift truck, to be alert, and
to avoid actions or conditions which can result in an
accident.
WARNING
Tipover can occur if the truck is improperly
operated. In the event of a tipover, injury or death
could result.

Safety Section
