maintenance work.
14. Do not modify the excavator,
otherwise it could lead to
unforeseen safety problems.
2. STARTING OF THE EXCAVATOR
1. Get into and out of the machine
safely.Always face the machine.
Always use handrails and available
steps and keep yourself well
balanced. Do not hold any of the
control levers and switches. Do not
jump on or off the machine, whether
stationary or in motion.
2. Start and control the excavator only
from the operator's seat. The driver
should not lean out of his seat when
the engine is running.
3. Before starting the engine, make
sure that all control levers (including
auxiliary control levers) are in their
neutral positions.
4. Before starting the engine, make
sure that the control levers, travel
lever, pedals and other control
elements are not stuck and can be
moved smoothly. If stuck, for
example, a lever may fail to return,
possibly putting you in danger. If
anything wrong is found,
immediately pinpoint the cause and

correct it.
5. Do not start the engine by jumping
the starter connections. Do not try
to circumvent using the starter
switch, otherwise the engine could
start suddenly and the excavator
could move.
6. Make sure that the dozer is on the
front side. (The dozer must be
raised.) If the swing frame has
been turned 180°, i.e. the dozer is,
seen from the operator, "behind",
then the travel direction is opposite
to the drive direction of the levers
(when activating the drive lever
forwards, the excavator, seen from
the operator, will move backwards).
7. Do not run the engine in closed or
badly ventilated rooms. Carbon
monoxide is colourless, odourless
and deadly.
8. Keep all safety equipment and
covers in place. Replace damaged
or missing safety devices.
9. Precautions against tipping over. In
order to secure safe operation,
keep away from steep slopes and
embankments. Do not swing the
bucket downwards. Lower the dozer
during digging. Keep the bucket as
low as possible while driving
upwards. Turn slowly on slopes. Do
not keep the excavator near the
edges of trenches and banks, as
the earth can give way due to the
weight of the excavator.
10. Watch out at all times where the
excavator is being moved to. Keep
an eye out for hindrances.
11. Keep enough distance from trench
and bank edges.
♦ Safety for children
Tragedy can occur if the operator is not
alert to the presence of children.
Children generally are attached to
machines and the work they do.
12. Never assume that children will
remain where you last saw them.
13. Keep children out of the work area
and under the watchful eye of
another responsible adult.
14. Be alert and shut your machine
down if children enter the work area.
15. Never carry children on your
machine. There is no safe place for
them to ride. They may fall off and
be run over or interfere with your
control of the machine.
16. Never allow children to operate the
machine even under adult
supervision.
17. Never allow children to play on the
machine or on the implement.
18. Use extra caution when backing up,
look behind and down-make sure
area is clear before moving.
19. When parking your machine if at all

possible park on a firm, flat and
level surface; if not, park across a
slope. Set the parking brake(s),
lower the implements to the ground,
remove the key from the ignition
and lock the cab door (if equipped)
and chock the crawlers or the
wheels.
3. AFTER OPERATION
Before leaving the machine,
• Bring the excavator to hard even
ground.
• Lower the attachments and the
dozer blade on the ground.
• Stop the engine.
• Lock all control levers.
• Remove the key.
4. SAFE LOADING AND
TRANSPORT OF THE
EXCAVATOR
1.Observe all regulations concerning
the transport of excavators on public
roads.
2.Use adequately long and robust
ramps when loading on a truck, (for
details see 'TRANSPORTING THE
EXCAVATOR ON A TRUCK")
3.Do not change the running direction
and to avoid a tipping over, do not try
to swing the attachment crosswise to
the loading ramps.
4.After loading of the excavator on a
truck, engage the swing lock pin.
Lower the attachment on the loading
plane and release the pressure from
the hydraulic system.
Block the crawlers with blocks and wire
down the excavator. After loading the
excavator on a truck, tie down the
undercarriage of the excavator with a
strong steel wire on the truck.
5. Do not brake abruptly with the
excavator loaded. Fatal accidents could
happen.
6. If the excavator is to tow another
machine, the load must be smaller than
the strength of the hook.
5. MAINTENANCE
Before doing maintenance work on the
excavator, place the machine on even
solid ground, lower the attachments on
the ground, stop the engine and release
the cylinder pressure by actuating the
levers. When dismantling hydraulic
parts, make sure that the hydraulic oil
has cooled down sufficiently to avoid
burns.
Start maintenance work carefully, e.g.
loosen screws slowly so that oil will not
squirt out.
1. Before doing work on the engine,
the exhaust system, the radiator and
the hydraulics, let the excavator cool
down sufficiently.
Max. drawbar pull at
coupling hook
7935 lbs. (35.3
kN)
Max. vertical load at
coupling hook

2. Turn off the engine at all times
when filling with fuel. Avoid spilling
and over-filling of fuel.
3. Smoking is prohibited while fuelling
and handling the battery! Keep
sparks and fire away from the fuel
tank and battery. Flammable gases
escape from the battery, especially
during charging.
4. Do not use or charge the refillable
type battery if the fluid level is
below the LOWER (lower limit level)
mark. Otherwise, the battery
component parts may prematurely
deteriorate, which may shorten the
battery's service life or cause an
explosion. Check the fluid level
regularly and add distilled water as
required so that the fluid level is
between the UPPER and LOWER
levels.
5. Read and follow "STARTING WITH
AN AUXILIARY BATTERY" in
"OPERATION OF THE ENGINE",
when starting with an auxiliary
battery.
6. To avoid short-circuiting the battery,
always remove the earth cable first
and attach the plus cable first.
7. Keep a first-aid box and a fire
extinguisher at hand at all times.
8. Do not open the radiator cap before
the radiator has cooled down
sufficiently.
First loosen the cap to the first stop
and allow the system enough time
to release the remaining pressure.
Then loosen the cap completely.
9. Leaking hydraulic fluid has enough
pressure to penetrate the skin and
cause serious injuries. Leakages
from pin holes can be totally
invisible. Do not use the bare hand
for checking on possible leakages.
Always use a piece of wood or
cardboard. It is strongly
recommended you use aface mask
or eye protection.
Should injuries occur with leaking
hydraulic fluid, contact a doctor
immediately. This fluid can cause
gangrene or serious allergic
reactions.
10. To avoid leakage of battery acid
which contains heavy metals, do not
throw the battery away.
11. Observe all laws and regulations
concerning the disposal of used oil,
coolants, solvents, hydraulic fluids,
battery acids and batteries.
12. To avoid fire, do not heat the
hydraulic components (tanks, pipes,
hoses, cylinders) before they have
been drained and washed.
13. Use a face mask or eye protection
to protect the eyes and respiratory
system against dust and other
foreign particles.

14. Do not crawl under the excavator if
the excavator is only supported by
the boom and arm or the dozer.
The excavator can tip over or lower
itself due to hydraulic pressure loss.
Always use safety struts or other
appropriate supports.
16. Fire prevention
Excavator and some attachments
have components that are at high
temperatures under normal
operating conditions. The primary
source of high temperatures is the
engine and exhaust system. The
electrical system, if damaged or
incorrectly maintained, can be a
source of arcing or sparks.
The following fire prevention
guidelines will help to keep your
equipment up and running
efficiently and keep the risk of fire to
a minimum.
• Blow off all accumulated debris
near hot engine exhaust
components such as turbocharger
and exhaust manifold as well as
exhaust pipes and muffler more
frequently when working in severe
conditions.
• Clean out all accumulated
flammable debris such as leaves,
straw, pine needles, branches, bark,
small wood chips and any other
combustible materials from inside
the machine belly pans or lower unit
structures as well as from area in
proximity to the engine.
• Inspect all fuel lines and hydraulic
hoses for wear or for deterioration.
Replace them immediately if they
begin to leak.
• Examine electrical wiring and
connectors frequently for damage.
Repair any wires that are loose or
frayed before operating the machine.
Clean all electrical connections and
tighten all electrical connections as
necessary.
• Inspect the exhaust system daily for
any signs of leakage. Check for
broken pipes and muffler and also
for loose or missing bolts, nuts and
clamps. If any exhaust leaks or
fractured parts are found, repairs
must be completed prior to operation.
• Always keep a multipurpose fire
extinguisher on or near the machine.
Be familiar with the operation of the
fire extinguisher.
