General Safety Essentials
Accessory Applications
The wheel loader has been designed primarily for
moving earth with a bucket. For use as a grapple or
for other object handling, contact Daewoo. Liftingwork applications are permitted in approved lift
configuration, to rated capacity only, with no sideloading (unless prohibited by local regulation).
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.
Working in rough terrain, use of an accessory
hydraulic hammer (breaker), demolition applications, or other hazardous operation may require
installation of additional protective structures to
safeguard the operator.
Static Tipping Load
The machine can lift a maximum of 14,500 kg
(31,967 lb) with the bucket in the Straight Ahead
position, and a maximum of 12,000 kg (26,455 lb)
with the bucket in the Fully Turned position. Hooks
and slings must be attached to an eye that is in the
center of the bucket. All lifts must be made with the
machine standing on a firm and level surface.
Loads must be balanced and supported evenly.
Use taglines 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.
NOTE
Before using the wheel loader to make lifts, check
the statutes at all levels of government that might
have jurisdiction. Some governing bodies may
require that all heavy lifting be done with a crane
that is specifically designed for making lifts. When
making lifts, always follow all instructions, guidelines, and restrictions for Safe Lifting in the
Operation and Maintenance and Shop Manuals.

CAUTION
Mega 300-III Shop Manual
SAFETY 1-5
Summary of Safety
Precautions for Lifting
To make safe lifts, the following items must be evaluated by the operator and the work-site crew.
• Condition of ground support
• Wheel loader configuration and attachments
• Load weight
• Safe rigging of the load
• Proper handling of the suspended load
Taglines 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.
Unauthorized Modifications
Any modification made without authorization or
written approval from Daewoo can create a safety
hazard, for which the machine owner must be held
responsible.
For safety’s sake, replace all OEM parts with the
correct authorized or genuine Daewoo part. For
example, not taking the time to replace fasteners,
bolts or nuts with the correct replacement parts
could lead to a condition in which the safety of critical assemblies is dangerously compromised.
Attachment Precautions
Options kits are available through your dealer.
Contact Daewoo for information on available oneway (single-acting) and two-way (double-acting)
piping/valving/ auxiliary control kits. Because
Daewoo cannot anticipate, identify or test all of the
attachments that owners may wish to install on their
machines, please contact Daewoo for authorization
and approval of attachments, and their compatibility
with options kits.
Avoid High-voltage Cables
Serious injury or death can result from contact or
proximity to high-voltage electric lines. The bucket
does not have to make physical contact with power
lines for current to be transmitted.
Use a spotter and hand signals to stay away from
power lines not clearly visible to the operator.
Depending upon the voltage in the line and atmospheric conditions, strong current shocks can occur
with the boom or bucket as far away as 4 m – 6 m
(13' 0" – 20' 0") from the power line. Very high
voltage and rainy weather could further decrease
that safety margin.
DANGER!!!
Unsafe use of the wheel loader 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!!!
1. NEVER wrap a tagline around your
hands or body.
2. NEVER rely on taglines or use the wheel
loader in lifting mode when wind gusts
are in excess of 48.3 km/h (30 mi/h). Be
prepared for any type of wind gust when
working with loads that have a large
surface area.
IMPORTANT
If you need more information or have any
questions or concerns about safe operating
procedures or working the wheel loader
correctly in a particular application or in the
specific conditions of your individual operating environment, please consult your local
Daewoo representative.
1-6 SAFETY
Mega 300-III Shop Manual
Before Starting to Dig, Contact Authorities
Below ground hazards also include natural gas
lines, water mains, tunnels and buried foundations.
Know what’s underneath the work-site before
starting to dig.
Be Aware of Height Obstacles
Any type of object in the vicinity of the boom could
represent a potential hazard, or cause the operator
to react suddenly and cause an accident. Use a
spotter or signal person working near bridges,
phone lines, work-site scaffolds, or other
obstructions.
Use Care on Loose Support
Working heavy loads over loose, soft ground or
uneven, broken terrain can cause dangerous side
load conditions and possible tipover and injury.
Travel without a load or balanced load may also be
hazardous.
If temperatures are changing, be cautious of dark
and wet patches when working or traveling over
frozen ground. Stay away from ditches, overhangs
and all other weak support surfaces. Halt work and
install support mats or blocking if work is required
in an area of poor support.
Use Solid Support Blocking
Never rely on lift jacks or other inadequate supports
when work is being done. Block wheels fore and aft
to prevent any movement.
Digging Beneath Overhangs
Digging beneath an overhang is dangerous. The
overhand could collapse on top of the operator and
cause serious injury or death. Go on to another
digging area before steep overhangs are formed.
Know the height and reach limits of the wheel
loader and plan ahead while working. Park wheel
loader away from overhangs before work shutdown.
Digging Beneath the Wheel Loader
Digging beneath the wheel loader is dangerous.
The earth beneath could collapse. This could cause
the wheel loader to tip, which could cause serious
injury or death to the operator. Working around
deep pits, trenching or along high walls may require
support blocks, especially after heavy rainfalls or
during spring thaws.
Sloping Terrain Requires Caution
Dig evenly around the work-site whenever possible,
trying to gradually level any existing slope. If it is
not possible to level the area or avoid working on a
slope, reducing the size and cycling rate of the
workload is recommended.
On sloping surfaces, use caution when positioning
the wheel loader prior to starting a work cycle. Stay
alert for instability situations in order to avoid
getting into them. For example, you should always
avoid working the bucket over downhill side of the
machine when parked perpendicular to the slope.
Avoid full extensions of the bucket in a downhill
direction. Lifting the bucket too high, too close to
the machine, while the wheel loader is turned uphill
can also be hazardous.
Stay Alert for People Moving through the Work
Area
• When loading a truck you should always know
where the driver is.
• Avoid loading over the cab of a truck even if
the driver is in a safe spot. Someone else could
have gone inside, for any number of reasons.
Avoid working where unseen passersby
might be.
• Slow down the work cycle and use slower travel
speeds in congested or populated areas. Use a
commonly understood signal so that other
members of the work crew can warn the operator to slow or halt work in an impending
hazardous situation.
DANGER!!!
Before starting any type of operation near
power lines (either above ground or buried
cable-type), you should always contact the
power utility directly and work out a safety
plan with them.
Mega 300-III Shop Manual
SAFETY 1-7
Operation
Be Prepared – Get to Know All Operating
and Safety Instructions
This is the Safety Alert Symbol. Wherever it
appears – in this manual or on safety signs on the
machine – you should be alert to the potential for
personal injury or accidents. Always observe safety
precautions and follow recommended procedures.
Operate While Seated at the Operator’s
Station ONLY
Never reach in through a window to work a control.
Do not try to operate the wheel loader unless you
are in the command position – seated at the
controls. You should stay alert and focused on your
work at all times but DO NOT twist out of the seat if
job activity behind you (or to the side) requires your
attention.
Use a spotter or signal person if you cannot see
clearly and something is happening behind you.
Replace damaged safety labels and lost or
damaged operator’s manuals.
Do not let anyone operate the machine unless they
have been fully and completely trained, in safety
and in operation of the machine.
Learn the Signal Words Used with the
Safety Alert Symbol
The words “CAUTION,”“WARNING,” and
“DANGER” used throughout this manual and on
labels on the machine indicate hazards or unsafe
practices. All three statements indicate that safety is
involved. Observe the precautions indicated whenever you see the Safety Alert “Triangle,” no matter
which signal word appears next to the “Exclamation
Point” symbol.
Before Starting the Engine
Do a “pre-start” safety check:
• Walk around your machine before getting in the
operator’s cab. Look for evidence of leaking
fluid, loose fasteners, misaligned assemblies or
any other indications of possible equipment
hazard.
• All equipment covers and machinery safety
guards must be in place, to protect against
injury while the machine is being operated.
• Look around the work-site area for potential
hazards, or people or property that could be at
risk while operation is in progress.
• NEVER start the engine if there is any indication that maintenance or service work is in
progress, or if a warning tag is attached to
controls in the cab.
• A machine that has not been used recently, or
is being operated in extremely cold temperatures, could require a warmup or maintenance
service prior to start up.
• Check gauges and monitor displays for normal
operation prior to starting the engine. Listen for
unusual noises and remain alert for other
potentially hazardous conditions at the start of
the work cycle.
• Check tire inflation and check tires for damage
or uneven wear. Perform maintenance before
operation.
CAUTION!!!
Indicates a hazardous situation that, if not
avoided, could result in minor or moderate
injury. It may also be used to alert against a
generally unsafe practice.
WARNING!!!
Indicates a hazardous situation that, if not
avoided, could result in serious injury or
death. It may also be used to alert against a
highly unsafe practice.
DANGER!!!
Indicates a hazardous situation that, if not
avoided, is very likely to cause death or
extremely serious injury. It may also be
used to alert against equipment that may
explode or detonate if handled or treated
carelessly.
1-8 SAFETY
Mega 300-III Shop Manual
Never Use Ether Starting Aids
An electric-grid type manifold heater is used for
cold starting. The glowing heater element can
cause ether or other starting fluid to detonate,
causing injury.
Mounting and Dismounting
• NEVER get on or off a moving machine. Do not
jump on/off. The entry/egress path should be
clear of mud, oil and spills and mounting hardware must be kept tight and secure.
• Always use handholds or steps and maintain at
least 3-point contact of hands and feet. Never
use controls as handholds.
• NEVER get up from the operator’s seat or
leave the operator’s station and dismount the
machine if the engine is running.
Observe General Safety Rules
Only trained and authorized personnel, with a good
knowledge and awareness of safe procedures, may
be allowed to operate or perform maintenance or
service on the wheel loader.
All personnel at the work-site should be aware of
assigned individual responsibilities and tasks.
Communication and hand signals used should be
understood by everyone.
Terrain and soil conditions at the job site,
approaching traffic, weather-related hazards and
any above or below ground obstacles or hazards
should be observed and monitored by all work crew
members.
Engine Ventilation
Engine exhaust gases can cause loss of judgment,
loss of alertness, and loss of motor control. These
gases can also cause unconsciousness, serious
injury and fatal accidents.
Make sure of adequate ventilation before starting
the engine in any enclosed area.
You should also be aware of open windows, doors
or ductwork into which exhaust may be carried, or
blown by the wind, exposing others to danger.
Take Time to Provide Good Visibility
Halt work if visibility is poor. Strong rains, snow,
fog and extremely dusty conditions can all obscure
visibility so badly that it is best to wait for weather
to change or dust to settle before continuing
operation.
Night work in areas of limited visibility should be
halted if installation of extra work lights on the
machine (or work area) is necessary.
Keep dirt and dust off of windows and off the lens
surfaces of work lights. Stop working if lights,
windows or mirrors need cleaning or adjustment.
Fuel, Oil and Hydraulic Fluid Fire Hazards
Add fuel, oil, antifreeze and hydraulic fluid to the
machine only in a well ventilated area. The machine
must be parked with controls, lights and switches
turned off. The engine must be off and any flames,
glowing embers, auxiliary heating units or sparkcausing equipment must be doused, turned off
and/or kept well clear of the machine.
Static electricity can produce dangerous sparks at
the fuel filling nozzle. In very cold, dry weather or
other conditions that could produce static
discharge, keep the tip of the fuel nozzle in
constant contact with the neck of the fuel filling
nozzle, to provide a ground.
Keep fuel and other fluid reservoir caps tight and
do not start the engine until caps have been
secured.
Boost Starting or Charging Engine Batteries
Turn off all electrical equipment before connecting
leads to the battery. This includes electrical
switches on the battery charger or boost starting
equipment.
When boost-starting from another machine or
vehicle do not allow the two machines to touch.
Wear safety glasses or goggles while required
parallel battery connections – positive to positive
and negative to negative – are made. (24 volt
battery units consisting of two series-connected
twelve volt batteries have a cable connecting one
positive terminal on one of the 12 volt batteries to a
negative terminal on the other battery. Booster or
charger cable connections must be made between
the non-series-connected positive terminals and
between the negative terminal of the booster
battery and the metal frame of the machine being
boosted or charged.) Refer to the procedure and
illustration in the Engine section of this book.
Mega 300-III Shop Manual
SAFETY 1-9
Connect positive cable first when installing cables
and disconnect the negative cable first when
removing them. The final cable connection, at the
metal frame of the machine being charged or
boost-started, should be as far away from the
batteries as possible.
Keep “Pinch Point” Areas Clear – Use Caution
in Reverse
Use a signal person in high traffic areas and whenever the operator’s view is not clear, such as when
traveling in reverse.
Anyone standing near the wheels, or working
assemblies of the attachment, is at risk of being
caught between moving parts of the machine.
Never allow anyone to ride on any part of the
machine or attachment, including any part of the
operator’s cab.
Travel Precautions
Engage frame lock for long-distance travel. When
traveling the wheel loader always keep lights on;
make sure that you are in compliance with all state
and local regulations concerning warning flags and
signs.
Attachment control levers should not be operated
while traveling.
Fold in work equipment so that the outer end of the
boom is as close to the machine as possible, and is
low – 203 mm – 304 mm (8" – 12") above ground.
Never travel over obstacles or slopes that will cause
the machine to tilt severely. Travel around any slope
or obstacle that causes 10 degrees tilt, or more.
Operate Carefully on Snow and Ice and in
Very Cold Temperatures
In icy cold weather avoid sudden travel movements
and stay away from even very slight slopes. The
machine could skid off to one side very easily.
Snow accumulation could hide or obscure potential
hazards. Use care while operating or while using
the machine to clear snow.
Warming up the engine for a short period may be
necessary, to avoid operating with sluggish or
reduced working capacity. The jolting shocks and
impact loads caused by bumping or bottoming the
boom or attachment are more likely to cause
severe stress in very cold temperatures. Reducing
work cycle rate and work load may be necessary.
Parking the Machine
Avoid making sudden stops, or parking the machine
wherever it happens to be at the end of the work
day. Plan ahead so that the wheel loader will be on
a firm, level surface away from traffic and away
from high walls, cliff edges and any area of potential water accumulation or runoff. If parking on
inclines is unavoidable, block the wheels to prevent
movement. Lower the bucket or other working
attachment completely to the ground, or to an
overnight support saddle. There should be no
possibility of unintended or accidental movement.
Shutdown Control Functions
After the bucket has been lowered to the overnight
storage position, move all the switches and controls
to the OFF position. Move the parking brake switch
to the locked position. This will apply the parking
brake. Move the pilot cut-off switch to the locked
position. This will disable the bucket control lever.
Move the key in the ignition switch to the OFF position, and remove the key from the switch.
Engage all lock-down security equipment that may
have been installed on the machine.
IMPORTANT
When hydraulic system maintenance or
service work must be performed, be aware
that accumulators in the system store fluid
under pressure after the system has been
shut down. To release the hydraulic pressure in the accumulators, operate the
control with the engine off until accumulator
pressure is completely dissipated.
1-10 SAFETY
Mega 300-III Shop Manual
Equipment
Rough Operation May Require Use of Certified
Safety Equipment
Work in mines, tunnels, deep pits or on loose or
wet surfaces could produce danger of falling rock,
roll over or hazardous flying objects. Additional
protection for the operator’s cab could be required
in the form of a FOPS/ Falling Object Protective
Structure, ROPS/Roll Over Protective Structure
and/or OPS/Operator Protective Structure reinforcement system.
Any reinforcement system that is installed on the
machine must pass safety and certification standards and carry appropriate labeling and rating
information. For example, the most often added
type of reinforcement system, FOPS, must meet or
exceed Society of Automotive Engineers standard
SAE J1356, “Performance Criteria for Falling Object
Guards for Wheel loaders.”
Never attempt to alter or modify any type of protective structure reinforcement system, by drilling
holes, welding or remounting or relocating
fasteners. Any serious impact or damage to the
system requires a complete integrity reevaluation.
Reinstallation, recertification and/or replacement of
the system may be necessary.
Install Additional Safety Equipment if
Conditions Require
When working with a breaker or in some shear
work applications, a front guard over the windshield
may be required. The windshield guard may or may
not be OPS/certified, depending upon the specific
application and working situation.
Laminate glass protection for the front, side or rear
windows may also be recommended depending
upon particular site conditions.
Contact your Daewoo distributor for available safety
guards and/or recommendations if there is any
danger of getting hit by objects that could strike the
operator’s cab. Make sure that all other work-site
crew members are kept well away from the wheel
loader and safe from potential hazards.
Movement Alarms
If the wheel loader is equipped with an audible
travel movement alarm, test the alarm on a daily
basis. The audible alarm should sound as soon as
the travel system is engaged.
Seat Belts Should Be Used at All Times
Whenever the engine is running, the operator
should be seated at the control station with the seat
belt properly engaged.
Keep a Fire Extinguisher at Hand
It is recommended that an appropriately sized
(2.27 kg [5 lb] or larger) multi-purpose “A/B/C” fire
extinguisher be mounted in the cab. Check and
service the fire extinguisher at regular intervals and
make sure that all work-site crew members are
adequately trained in its use.
Maintain Standard Safety Equipment in Good
Condition
Machinery guards and body panel covers must be
in place at all times. Keep well clear of rotating
parts. Pinch point hazards such as cooling fan and
alternator drive belts could catch hair, jewelry or
oversize or very loose clothing.
Safety labels must be replaced if they are damaged
or become unreadable. The information on labels
gives work crew members an important safety
reminder. Part numbers for each label and required
mounting locations are shown on Pages
1-2 through 1-4 of this section.
Safety-critical Parts Must Be Replaced
Periodically
Replace the following fire-related components as
soon as they begin to show any sign of wear, or at
regular periodic intervals, whether or not deterioration is visible:
• Fuel system flexible hoses, the tank overflow
drain hose and the fuel filler cap.
• Hydraulic system hoses, especially the pump
outlet lines and front and rear pump branch
hoses.
• Keep mounting brackets and hose and cable
routing straps tight. Hose routing should have
gradual bends.
Hydraulic Cylinder Seals Require Periodic
Replacement
Check cylinder drift rate at regular intervals.
Maximum allowable rates are included at the end of
the Hydraulic section in the Shop Manual. Overhaul
seal kits are available through Daewoo.
Mega 300-III Shop Manual
SAFETY 1-11
High Pressure Hydraulic Lines Can Store
a Great Deal of Energy
Exposed hydraulic hoses on the arm or boom could
react with explosive force if struck by a falling rock,
overhead obstacle or other job site hazard. Extra
safety guards may be required. NEVER allow hoses
to be hit, bent or interfered with during operation.
The Operator’s Cab Should Be Kept Clean
Clean grease and dirt from pedals and controls.
This contributes to safe operation.
Cleaning also provides an opportunity to inspect
equipment. Minor damage can be repaired or
corrected before major problems result.
Keep the cab floor and consoles free of tools and
personal items.
Wear Eye Protection and Safety Clothing – Use
Proper Tools
Contain long hair, and avoid wearing loose clothes
or jewelry that could get caught in controls.
Full eye protection, a hard hat, safety shoes and
gloves may be required at the job 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.
Breathing Masks, Ear Protection May Be
Required
Do not forget that some risks to your health may
not be immediately apparent. Exhaust gases and
noise pollution may not be visible, but these
hazards can cause disabling or permanent injuries.
NOTE
The sound level in the closed operator’s cab is 75
dB(A). Additional information on the machine sound
and vibration levels can be found in the Shop
Manual.
Asbestos Fiber Hazard
Materials containing asbestos fiber can be present
on the job site. Breathing air that contains asbestos
fiber can ultimately cause serious or fatal lung
damage. To prevent lung damage from asbestos
fiber, observe the following precautions.
1. Use a respirator that is approved for use in an
asbestos-laden atmosphere.
2. Use water for cleaning and for keeping dust
down.
3. NEVER use compressed air for cleaning.
Battery Electrolyte and Explosive Gases
Can Be Lethal
Flush eyes with water for 10 – 15 minutes if acid is
splashed in the face. Anyone who swallows acid
must have immediate medical aid. Call the Poison
Control listing in the front cover of the telephone
directory.
Explosive battery gas can be set off by sparks from
incidental contact or static discharge. Turn off all
switches and the engine when working on batteries.
Keep battery terminals tight. Contact between a
loose terminal and post can create an explosive
spark.
Disconnect Batteries Before Electrical Service
or Electrical Welding
Remove cable to negative terminal first when
disconnecting cable. Connect positive terminal
cables first when installing a battery.
Use Low Heat Portable Lighting
Hot surfaces on trouble lights or portable work
lights can set off fuel or battery explosive gases.
Maintenance
Use Warning Tag During Service
Alert others that service or maintenance is being
performed and tag operator’s cab controls – and
other machine areas if required – with a warning
notice.
Warning tags for controls are available from
Daewoo distributors; see Page 1-1 for more
information.
Do Not Run the Engine if Repairs or Work Are
Being Performed Alone
You should always have at least two people
working together if the engine must be run during
service. One person needs to remain in the operator’s seat, ready to work the controls or stop the
machine and shut off the engine.
1-12 SAFETY
Mega 300-III Shop Manual
Always Use Adequate Equipment Supports
and Blocking
Do not allow weight or equipment loads to remain
suspended. Lower everything to the ground before
leaving the operator’s seat. Do not use hollow,
cracked or unsteady, wobbling weight supports. Do
not work under any equipment supported solely by
a lift jack.
Do Not Work on Hot Engines or Hot Cooling
or Hydraulic Systems
Wait for the engine to cool off after normal operation. Park the wheel loader on a firm, level surface
and lower all equipment before shutting down and
switching off controls. When engine lube oil,
gearbox lubricant or other fluids require change,
wait for fluid temperatures to decrease to a
moderate level before removing drain plugs.
NOTE
Oil will drain more quickly and completely if it is
warm. Do not drain fluids at temperatures
exceeding 95°C (203°F), however do not allow full
cool-down.
Cool-down is Required Prior to Radiator
or Reservoir Checks
Stop the engine and allow heat to dissipate before
performing service on the engine radiator or
hydraulic fluid reservoir. Both assemblies have air
vent levers at or near the filler cap for venting builtup air pressure. Release the levers before trying to
take off filler caps and LOOSEN CAPS SLOWLY,
prior to removal.
Pressurized Hydraulic Oil Fluid Leaks
Can Be Dangerous
Fluid leaks from hydraulic hoses or pressurized
components can be difficult to see but pressurized
oil has enough force to pierce the skin and cause
serious injury.
Always use a piece of wood or cardboard to check
for suspected hydraulic leaks. Never use your
hands or expose your fingers.
Obtain immediate medical attention if pressurized oil pierces the skin.
Use Correct Replacement Fasteners Tightened
to Proper Torque
Refer to the General Maintenance section of the
Shop Manual for information on tightening torques
and recommended assembly compounds and
always use the correct part.
Poor or incorrect fastener connections can dangerously weaken assemblies.
Dispose of All Petroleum-based Oils and Fluids
Properly
Physical contact with used motor oil may pose a
health risk. Wipe oil from your hands promptly and
wash off any remaining residue.
Used motor oil is an environmental contaminant
and may only be disposed of at approved collection
facilities. Never drain any petroleum-based product
on the ground or dispose of old oil in municipal
waste collection containers, or in metropolitan
sewer systems or rural landfills.
Check state and local regulations for other requirements.
Check Tire Pressure and Condition
Maintain tire pressure but do not over inflate.
Inspect tires and wheels daily. When inflating tires,
follow procedures in the Maintenance section,
which include using an extension to allow you to
avoid standing in front of or over a tire. Do not
change a tire unless you have both experience and
proper equipment.
WARNING!!!
Failure to obtain prompt medical assistance
could result in gangrene or other serious
damage to tissue.

Shipping and Transportation
Obey State and Local Over-the-Road
Regulations
Check state and local restrictions regarding weight,
width and length of a load prior to making any other
preparation for transport.
The hauling vehicle, trailer and load must all be in
compliance with local regulations governing the
intended shipping route.
Partial disassembly or tear-down of the wheel
loader may be necessary to meet travel restrictions
or particular conditions at the job site.
Refer to the Transportation and Shipping section of
the Operation and Maintenance Manual.

Weights are approximations of estimated
average volume and mass. Exposure to rain,
snow or ground water; settling or compaction
due to overhead weight and chemical or
industrial processing or changes due to thermal
or chemical transformations could all increase
the value of weights listed in the table.
IMPORTANT
Preventive Maintenance
Periodic checks and replacement of oil, grease,
filters, etc. must be made at specific intervals, to
keep the machine in good working condition. The
following pages describe the items to be checked,
the lubricants to be used, and the time interval
between each check.
NOTE
The time interval between each service check may
need to be shortened if the machine is operating in
severe atmospheric conditions. Machines working
in extremely hot or dusty conditions will require
more frequent service checks. The total hours of
machine operation are determined by the hour
meter that is located on the front instrument panel.
Safety Precautions
1. Before performing any maintenance checks,
move the pilot cutoff switch to the locked position. Place a warning tag on the controls so
that no one begins to operate the machine
while the maintenance checks are being
performed.
2. Clean up all fuel spills. Fuel spills are
hazardous, especially around the engine.
3. Inspect all fuel lines for leakage. Replace any
lines, fittings, O-rings, or filters that show
signs of wear or damage.
4. If a test procedure requires the engine to be
running, keep all unnecessary personnel away
from the machine.

IMPORTANT
Do not use lubricants other than those
recommended, without prior written
approval from Daewoo.
CAUTION!!!
Do not mix oils from different manufacturers. Daewoo does not endorse specific
brands but does suggest that owners select
quality oils whose suppliers provide assurance that required standards will always be
met or exceeded.
IMPORTANT
Fluctuating daily or weekly extremes of
temperature, or operation in sub-zero
freezing weather may make it impractical to
use straight weight lubricants. Use good
judgement in selecting lubricant types that
are appropriate for climate conditions.
