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,
transportation, 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 truck 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.

Information Section

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.
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".

who gives them. Accept signals from one person
only.
Always use the overhead guard. The overhead
guard is intended to protect the lift truck operator
from overhead obstructions and from falling objects.
A truck that is used for handing small objects or
uneven loads must be fitted with a load backrest.
If the lift truck must be operated without the
overhead guard in place due to low overhead
clearance, use extreme care. Make sure there is no
possibility of falling objects from any adjacent
storage or work area. Make sure the load is stable
and fully supported by the carriage and the load
backrest extension (if equipped).
Do not raise loads any higher than necessary and
never raise a load higher than 1830 mm (72 in) with
the overhead guard removed.
Always use load backrest extension when the
carriage or attachment does not fully support the
load. The load backrest extension is intended to
prevent the load or any part of the load from falling
backwards into the operator's station.
When operating the lift truck, do not depend only on
flashing lights or back-up alarm (if equipped) to warn
pedestrians.
Always be aware of pedestrians and do not proceed
until the pedestrians are aware of your presence
and intended actions and have moved clear of the
lift truck and/or load.
Do not drive lift truck up to anyone standing in front
of an object.
Obey all traffic rules and warning signs.
Keep hands, feet and head inside the operator
station. Do not hold onto the overhead guard while
operating the lift truck. Do not climb on any part of

Do not use steam, solvent, or high pressure to clean
electrical components.
Report all needed repairs.

Safety Section
11
Lift Chains
Inspect the part of the chain that is normally
operated over the crosshead roller. When the chain
bends over the roller, the movement of the parts
against each other causes wear.
Inspect to be sure that chain link pins do not extend
outside of the bore hole.
If any single link pin is extended beyond its
connecting corresponding link, it should be
suspected of being broken inside of its bore hole.
Inspect the chain anchor and the anchor links for
wear.
Do not change any factory set adjustment values
(including engine rpm setting) unless you have both
authorization and training. Especially Safety
equipment and switches may not be removed or
adjusted incorrectly. Repairs, adjustments and
maintenances that are not correct can make a
dangerous operating condition.
For any checkup, repair, adjustments, maintenance
and all other work concerning your forklift truck,
please contact your DOOSAN dealer. We would like
to draw your attention to the fact that any secondary
damages due to improper handling, insufficient
maintenance, wrong repairs or the use of other than

(30 psi) for cleaning purposes.
Fluid Penetration
Always use a board or cardboard when checking for
a leak. Escaping fluid under pressure, even a
pinhole size leak, can penetrate body tissue,
causing serious injury, and possible death. If fluid is
injected intoyour skin, it must be treated by a doctor
familiar with this type of injury immediately.
Crushing or Cutting Prevention
Support equipment and attachments properly when
working beneath them. Do not depend on hydraulic
cylinders to hold it up. Any attachment can fall if a
control is moved, or if a hydraulic line breaks.
Never attempt adjustments while the lift truck is
moving unless otherwise instructed or 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.

Safety Section
14
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 orother debris can fly offobjects 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.
Burn Prevention
Oils
Hot oil and components can cause personal injury.
Do not allow hot oil or components to contact the
skin.
At operation temperature, the hydraulic tank is hot
and can be under pressure.
Remove the hydraulic tank filter cap only after the
engine has been stopped and the filter cap is cool
enough to remove with your bare hand.
Remove the hydraulic tank filter cap slowly to relieve
pressure.
Relieve all pressure in air, oil fuel or cooling systems
before any lines, fittings or related items are
disconnected or removed.
Batteries
Only trained and designated personnel should
inspect, recharge or exchange batteries.
Always wear protective glasses when working with
batteries.
Service, exchange and handle batteries only in
authorized areas when proper safety and ventilation
facilities are provided.
Do not smoke, or expose battery to sparks or flame
when checking, charging or servicing battery. Keep
chains and metallic tools away from top of battery.
Batteries give off flammable fumes which can
explode.
Highly explosive gases are especially hazardous
toward the end of the charging period as the battery
approaches a full charge condition.
Electrolyte is an acid and can cause personal injury
if it contacts skin or eyes.
Service batteries in accordance with battery
manufacture instructions.
Refer to the topic "Batteries" in the "Maintenance
Section" of this manual.

Safety Section
15
Fire or Explosion Prevention
All fuels, most lubricants and some coolant mixtures
are flammable.

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.
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.
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.
 End fittings damaged or leaking.
 Outer covering chafed or cut and wire
reinforcing exposed.
 Outer covering ballooning locally.
 Evidence of kinking or crushing of the flexible
part of hose.
 Armoring embedded in the outer cover.
 End 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.
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.

Safety Section
16
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 tipover, injury or death
could result.

Safety Section
17
The "Survive in tipover" warning is located on the
overhead guard. It shows the proper use of the
operator restraint system.
