For Safe Driving
IMPORTANT:
Remove the protective (rust preventative) aluminum cover wrapped around the cylinder rods immedi-
ately after receiving the machine. If the machine is left with the covers on, water can collect on the
inside of the cover, which will be the cause for rust to develop on the cylinder rod.
In the case of transportation by sea, sea water salt adheres to the machine making rust easier to
develop. Immediately follow the measures below after receiving a machine that has been transported
by sea. If the measures are not taken, the machine will develop rust easily.
1. Confirm that there are no salt deposits on the 3. If Storage Is To Be Continued

making turns on slopes and hills. In addition,
even if you try to stop a turn, the effect could be
delayed due to the force of inertia.
● Attachment reinforcement should be done as
needed.

the machine and checking the surroundings, sit
in the operator’s seat.
2. Put the gate lock lever at the locked position.
3. Sit in the operator’s seat and adjust the position
so that the levers and pedals can be easily op-

4. Put the operation levers into neutral.
Cautions for starting the engine

1. When it is cold, the engine becomes harder to
start because the oil viscosity increases and the
battery performance decreases. Start the en-
gine at the first trial if possible.
2. Sound the horn to alert people in the surround-
ing area.

It is also very dangerous in particular to swing it
towards the down side of slope with the bucket
loaded with soil and the like.
(The machine may slide or turn over.)
4. Before traveling on a slope, clean the shoe if it
is clogged and take other precautions to prevent
slipping.
5. The maximum slope climbing ability is 35°
(70%). This value varies depending on the shoe
type and the road surface, limit traveling to
slopes of 30° or less.
CAUTION
Do not operate the engine with the machine at
35°.
The engine or hydraulic devices may be dam-
aged.

during excavation operations.
Take care that it does not sink too much.

3. If the machine sinks in water or soil up to the

swing body, grease replacement and mainte-
nance is necessary. Stop operations and con-

● Tow the machine slowly in order to lessen
the impact on the machine.
● Connect the excavator and towing vehicle

After Storage (when the machine is
used again)
1. Check the levels of oil and water and fill as nec-

Especially check carefully if the coolant is in.
Since the lubricants and grease deteriorate dur-
ing storage, check them carefully when the ma-
chine is used again.
2. Completely wipe off the anti-rust oil.
3. After starting the engine, take enough time to
warm it up and repeat the travel, swing and dig-
ging operations several times each.

WARNING
● Sufficient care is necessary during inspection and maintenance.
● Be especially careful about fire. (Do not smoke while working.)
● Wipe off any diesel fuel that is spilled during refilling, inspection or maintenance, because it may
cause a fire.
● Fuel leaking from the fuel hose, injection pump, fuel filter or joint may result in a fire. If any fuel
leakage is found, repair the area immediately.
● Do not use any substitute fuel because it may cause poor performance or even a fire.

CAUTION
Check the drained oil for foreign matter such
as metallic chips or powder. (If any foreign
matter is found, contact our Service Shop.)

Cleaning Crawler
• As necessary
●After finishing work on wet surface ground, re-
move the earth and mud attached between
shoe and travel unit (sprocket). If left with
earth attached, the earth gets solid and may
cause damage to shoe and the travel perfor-

Maintenance Troubleshooting
To extend the machine service life and improve the rate of operation, daily inspection and lubrication are
necessary as well as for isolating any problem found and dealing with it. If the machine is operated with the
problem uncorrected, it may cause major problem and sometimes lead to a serious accident or injury.
If problem occurs, search for the cause in the items described below and make adjustments, repairs, or take
measures as necessary. If the cause is not identified, contact our dealer or Service Shop.

Inspection and maintenance when using the breaker: we recommend having

Contamination and deterioration of the hydraulic oil tends to be progress quickly since breaker work is ex-
tremely harder for the hydraulic shovel compared with excavation work.
If the machine is continuously used with contaminated or deteriorated hydraulic oil, it can cause malfunction of
the control valves, earlier wear of the hydraulic pump and damage to the hydraulic oil circuit as a hole. Carry
out inspection and maintenance of hydraulic oil periodically as outlined below:

Cleaning Operation
The purpose of cleaning oil is to remove the contam-
inants and sludge by filtering hydraulic oil through a
cleaning device.
Normally, the hydraulic system of a construction
machine is installed with various filters, and if they
are maintained properly, most of the contaminants
and sludge is exhausted out of the circuits. How-
ever, fine particles (approximately 10 micron or
smaller) that cannot be collected by the filters con-
tinues to circulate through the circuits.
An oil cleaning device is extremely effective for ex-
tending the life of hydraulic oil since it can collect
fine particles (approx. 5 micron) that passes freely
through the filters installed inside the hydraulic sys-
tem.

caused by water in the system, due to working
with cylinders underwater, may void warranty.)
Lift the attachment out of the water frequently
and inspect the cylinder rod and seals for dam-
age. A damaged cylinder rod or damaged seal
can allow water to enter the cylinder and the
hydraulic system. Water in the hydraulic system
can cause serious damage to all hydraulic com-
ponents in the hydraulic system including the
pump. Check the hydraulic reservoir for water
frequently (at least daily) when operating with a
cylinder underwater. If water is found in the
hydraulic reservoir, the entire system must be
cleaned and flushed to remove all the water.
Repair the cause for the water in the system
and refill the system with new hydraulic oil.

counterweight is installed and the attachment is re-
moved, the machine may tip over backward. If the
