Operator Restraint System (If Equipped)
This manual contains safety, operation and
maintenance information for the DAEWOO operator
restraint system. Read, study and keep it handy.
WARNING
Your DAEWOO 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 DAEWOO
operator restraint system.
Photographs or illustrations guide the operator
through correct procedures of checking, operation
and maintenance of the DAEWOO 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 DAEWOO operator restraint
system can minimize injuries. The DAEWOO
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”.

pinhole size leak, can penetrate body tissue,
causing serious injury, and possible death. If fluid is
injected into your 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 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 DAEWOO
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 DAEWOO invalidates DAEWOO'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
DAEWOO dealer for mounting guidelines.

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 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 DAEWOO 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.
Do not approach a warm tire closer than the
outside of the area represented by the shaded area
in the above drawing.

Safety Section
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.

Warning Signs and Labels
Your DAEWOO 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 DAEWOO 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.

Avoiding Lift Truck Tipover
Lift Truck Stability
Counterbalanced lift truck design is based on the
balance of two weights on opposite sides of a
fulcrum (the front axle). The load on the forks must
be balanced by the weight of the lift truck. The
location of the center of gravity of both the truck
and the load is also a factor. This basic principle is
used for picking up a load. The ability of the lift
truck to handle a load is discussed in terms of
center of gravity and both forward and sideways stability.
Center of Gravity (CG)
Stability and Center of Gravity
The stability of the lift truck is determined by the
location of its CG; or, if the truck is loaded, the
combined CG of the truck and load. The lift truck
has moving parts and, therefore, has a CG that
moves. The CG moves forward or backward as the
mast is tilted forward or backward. The CG moves
up or down as the mast moves up or down. The CG
and, therefore, the stability of the loaded lift truck,
are affected by a number of factors such as:
z the size, weight, shape and position of the load
z the height to which the load is lifted
z the amount of forward or backward tilt
z tire pressure
z dynamic forces created when the lift truck is
accelerated, braked or turned
z condition and grade of surfaces on which the lift
truck is operated
The point within an object, at which the whole
weight of the object may be regarded as being
concentrated, is called the center of gravity or CG.
If the object is uniform, its geometric center will
coincide with its CG. If it is not uniform, the CG
could be at a point outside of the object. When the
lift truck picks up a load, the truck and load have a
new combined CG.
These same factors are also important for unloaded
lift trucks. They tip over sideways easier than a
loaded lift truck carrying its load in the lowered
position.
-21-
Safety Section
Lift Truck Stability Base
For the lift truck to be stable (not tip over forward or
to the side), the CG must stay within the area of the
lift truck stability base – a triangular area between
the front wheels and the pivot of the steer wheels. If
the CG moves forward of the front axle, the lift truck
will tip forward. If the CG moves outside of the line
on either side of the stability base, the lift truck will
tip to the side.
WARNING
Dynamic forces (braking, acceleration, turning)
also affect stability and can produce tipover
even when the CG is within the stability
triangle.
mast, and having no special-purpose attachment.
In addition, the capacity load assumes that the load
center is no further from the top of the forks than it
is from the face of the backrest. If these conditions
do not exist, the operator may have to reduce the
safe operating load because the truck stability may
be reduced. The lift truck should not be operated if
its capacity/nameplate does not indicate capacity
load.
NOTE: If the load is not uniform, the heaviest
portion should be placed closer to the
backrest and centered on the forks.
NOTICE
1. Capacity/Nameplates originally attached to
forklifts sold by DAEWOO shall not be removed,
altered or replaced without DAEWOO’s approval.
2. DAEWOO assumes no responsibility for lift
trucks placed in service without a valid DAEWOO
Nameplate.
3. If necessary to change your specification, contact
your DAEWOO lift truck dealer.
Capacity Load (Weight and Load Center)
The capacity load of the lift truck is shown on the
capacity/nameplate riveted to the truck. It is
determined by the weight and load center. The load
center is determined by the location of the CG of
the load.
The load center shown on the nameplate is the
horizontal distance from the front face of the forks,
or the load face of an attachment, to the CG of the
load. The location of the CG in the vertical direction
is the same as the horizontal dimension.
Remember that, unless otherwise indicated, the
capacity load shown on the nameplate is for a
standard lift truck with standard backrest, forks and

Safety Rules
Only properly trained and authorized personnel
should operate forklift trucks. Wear a hard hat and
safety shoes when operating a lift truck. Do not
wear loose clothing.
Safety Section
Do not operate a lift truck unless you are in the
operator's seat.
Keep arms, legs and head inside the confines of
the operator's area. Keep hands and feet out of the
mast assembly.
Inspect and check the condition of your forklift truck
using the operator's check list before starting work.
Immediately report to your supervisor any obvious
defects or required repairs.
Do not operate your truck in unauthorized areas.
Know your forklift truck and think safety.
Do not compromise safety.
Follow all safety rules and read all warning signs.
Do not start, stop, turn or change direction
suddenly or at high speed. Sudden movement can
cause the lift truck to tip over. Slow the speed of
your truck and use the horn near corners, exits,
entrances, and near people.
Never operate a lift truck with wet hands or shoes.
Never hold any controls with grease on your hands.
Your hands or feet will slide off of the controls and
cause an accident.
-23-
Safety Section
Do not raise anyone on the forks of your lift truck
unless using an approved safety cage.
Do not let other people ride on the truck.
Lift trucks are designed to carry loads, not people.
Do not operate your truck without the load backrest
extension and overhead guard. Keep the load
against the backrest with the mast tilted backward
Do not overload. Always handle loads within the
rated capacity shown on the capacity plate.
Do not add extra counterweight to the truck. An
overload can cause the truck to roll over and cause
injury to personnel and damage to the lift truck.
Do not drive on soft ground.
Observe all signs, especially those on maximum
permitted floor loadings, elevator capacities and
clearance heights.
Handle loads carefully and check them closely for
stability and balance.
Do not lift or move loads that are not safe. Do not
pick up an off center load. Such a load increases
the possibility of a tipover to the side. Make sure
loads are correctly stacked and positioned across
both forks. Always use the proper size pallet.
Position the forks as wide as possible under the
load. Position loads evenly on the forks for proper
balance. Do not lift a load with one fork.
Do not drive on slippery surfaces.
Sand, gravel, ice or mud can cause a tipover.
If unavoidable, slow down.
-24-
Safety Section
Do not permit anyone to stand or walk under the
load or lifting mechanism. The load can fall and
cause injury or death to anyone standing below.
Look out for overhead obstructions when raising or
stacking loads. Do not travel with a raised load. Do
not travel with the mast raised. The lift truck can roll
over and cause injury or death to you or other
personnel.
Do not elevate the load with the mast tilted forward.
Do not tilt the elevated loads forwards.
This will cause the lift truck to tip over forward.
Do not jump off if your truck starts to tip over.
Stay in your seat to survive.
Do not move loose loads that are higher than the
load backrest.
Be alert for falling loads when stacking.
Travel with the load tilted back and the forks as low
as possible.
This will increase stability to the truck and load and
permit better visibility for you.
Go up ramps in forward direction and down ramps
in reverse direction when moving loads.
Never elevate a load with the forklift truck on an
incline.
Go straight off and straight down. Use an assistant
when going up or down a ramp with a bulky load.
-25-
Safety Section
Do not stack or turn on ramps.
Do not attempt to pick-up or deposit a load unless
the lift truck is level. Do not turn on or drive across
an incline.
Do not go over rough terrain. If unavoidable, slow
down.
Cross railroad tracks slowly and diagonally
whenever possible. A railroad crossing can give a
loaded forklift truck a real jolt. For smoother
crossing, cross the railroad diagonally so one wheel
crosses at a time.
Do not drive in forward direction when loads restrict
your visibility. Operate your lift truck in reverse to
improve visibility except when moving up a ramp.
Be careful when operating a lift truck near the edge
of a loading dock or ramp. Maintain a safe distance
from the edge of docks, ramps and platforms.
Always watch tail swing.
The truck can fall over the edge and cause injury or
death.
Avoid running over loose objects.
Look in the direction of travel. Look out for other
persons or obstructions in your path of travel.
An operator must be in full control of his lift truck at
all times.
Do not operate on bridge plates unless they can
support the weight of the truck and load.
Make sure that they are correctly positioned.
Put blocks on the vehicle you enter to keep it from
moving.
-26-
Safety Section
Do not operate your truck close to another truck.
Always keep a safe distance from other trucks and
make sure there is enough distance to stop safely.
Never overtake other vehicles.
Do not use your lift truck to push or tow another
truck.
Do not let another push or tow your truck.
If a truck will not move, call a service technician.
Park your lift truck in authorized areas only. Fully
lower the forks to the floor, put direction lever in
NEUTRAL position, engage the parking brake, and
turn the key to the OFF position. Remove the key
and put blocks behind the wheels to prevent the
truck from rolling. Shut off your forklift truck when
leaving it unattended.
Check the condition of your forklift truck after the
day's work.
Forklift trucks may only be refueled at specially
reserved locations. Switch off the engine when
refueling.
Smoking and handling of naked flames during
refueling are strictly prohibited. This prohibition also
applies during the changing of the LPG (liquefied
propane gas) tank.
Mop up spilt fuel and do not forget to close the fuel
tank before restarting the engine.

exhaust gas. In order to obtain maximum effect
from the catalyst, an accurate control of the air fuel
MI-04 LP System
The SECM makes any necessary corrections to the
air fuel ratio by controlling the inlet fuel pressure to
the air/fuel mixer by modulating the fuel trim valve
(FTV) connected to the regulator. Reducing the fuel
pressure leans the air/fuel mixture and increasing
the fuel pressure enriches the air/fuel mixture. To
calculate any necessary corrections to the air fuel
ratio, the SECM uses a number of different sensors
to gain information about the engines performance.
Engine speed is monitored by the SECM through a
variable reluctance (VR) sensor. Intake manifold air
temperature and absolute pressure is monitored
with a (TMAP) sensor. The MI-04 is a drive by wire
