OPERATION

OPERATING THE MACHINE

STOPPING TRAVEL

• Park the machine on a flat, rigid and

safe ground. Set the parking brake. If

you must park on a slope, chock the

tracks to block the machine.

• If any control is accidentally touched

when the safety lock lever is not locked,

the machine may suddenly move and

cause serious injury or death.

• Note that the dozer blade, boom swing

and auxiliary hydraulic controls cannot

be locked, even when the safety lock

lever is set to the locked position.

Do not carelessly touch these controls.

Never stop running the machine suddenly

except in emergency. Stop in good time,

if possible.

1. Set the left and right travel levers slowly to

the neutral position. The machine stops.

CAUTIONS ON TRAVELING ON SLOPES

Traveling posture on slopes

Climbing slopes

• Never travel on slopes that are too

steep for the machine to maintain its

stability. Note that in reality, the

90°~110°

machine’s performance decreases on

slopes due to its poor working

condition.

• When traveling on slopes, lower the

20~30cm

bucket to a height of 20 to 30 cm (8 to

(8 to 12in)

12 in.) above the ground. When climbing

• When traveling on slopes or grades,

drive slowly in 1st (low) speed.

Descending slopes

• When climbing a hill, keep the

operator’s seat facing the hillside. When

descending a hill, keep the operator’s

either case, travel must be done while

paying attention to the ground in front

20~30cm (8 to 12in)

AG7A035PE

When descending slopes of 15° or more,

slow down the engine speed and maintain

the machine posture as shown in the figure

above.

• Do not change directions on slopes or

traverse slopes. First return to a flat

surface, and then take an alternative

path.

• The machine may slip sideways even on

a slight slope if they are covered with

grass or dead leaves, or when traveling

on a wet metal plate or frozen surfaces.

Do not allow the machine to position

sideways to slopes.

When digging wide ditches, dig the sides

first, and then dig the center.

1. Perform the steps 1 to 4 above for both

crawlers.

2. Dig the bucket into the ground in front of

the machine.

Be sure to lock the following places:

If you must park on a slope or incline,

park the machine securely and block

the movement of the machine.

• When parking on a street, use barriers,

caution signs, lights, etc., so that the

machine can easily be seen even at

night to avoid collision with other

Disposing of wastes

• Always collect oil that is drained from the

machine in containers. Improperly

disposed waste oil can cause

environmental harm.

• Follow appropriate laws and regulations

when disposing of harmful objects such as

oil, fuel, cooling water, coolant, filters and

batteries.

Check after maintenance

• Gradually increase the engine speed from a

low idle to maximum speed and check that

there is no oil or water leaking from

serviced parts.

• Operate each control lever and check that

FUEL AND LUBRICANT TABLE

Select the appropriate fuel, lubricant and grease according to the temperature by referring to

the table below.

• Regardless of the specified time, change the oil if it becomes too dirty or degraded.

• When refilling, never mix oils of different brands. If a brand is to be changed, replace the

whole fuel/oil.

To maintain the performance and service life of the engine,

always use clean and high-quality fuel.

• To avoid freezing in cold climates, use a diesel fuel that still

functions when the temperature is at least 12°C (21.6°F) below

the lowest expected ambient temperature.

• Use a diesel fuel that has a cetane number of 45 or higher.

When operating at a very low temperature or at a high altitude,

a higher cetane number fuel will be required.

• Use fuel with sulfur content of less than 0.1% by volume.

Fuel tank

Diesel fuel

Especially in the U.S.A. and Canada, ultra-low sulfur fuel

should be used.

A higher sulfur content fuel may cause sulfuric acid corrosion

in the cylinders of the engines.

• Never mix kerosene, used engine oil, or residual fuel with the

diesel fuel. Use of kerosene is prohibited.

• Poor quality fuel can reduce engine performance and / or

cause engine damage.

• Fuel additives are not recommended. Some fuel additives may

cause poor engine performance.

MAINTENANCE

SAFETY-CRITICAL PARTS

The material of the safety-critical part listed above tends to change over time and cause wear

or deterioration. It is difficult to determine the degree of deterioration at the periodic inspection,

and thus they need to be replaced with new ones after a certain time to maintain their proper

performance even if they appear in good condition. Note that regardless of the replacement

schedule, replacement must be performed immediately if a symptom of wear is found. If a

hose clamp is deformed or cracked, replace it together with the hose immediately. When

replacing the safety-critical parts, ask your sales or service dealer.

In addition to the safety-critical parts, inspect the hydraulic hoses and retighten or replace as

necessary. When replacing the hydraulic hoses, replace the O-rings and seals at the same

time.

Check the fuel and hydraulic hoses according to the periodic schedule described below.

Refer to “Maintenance”.

MAINTENANCE

WALK-AROUND INSPECTION

WALK-AROUND INSPECTION

Perform the following inspections every day before starting the engine for the first time.

• Before operating, perform the walk-around inspections and make repairs immediately

where necessary.

• Be sure to secure the engine hood or cover before working the inside. Do not keep the

hood or cover open on a windy day or if the machine is parked on a slope.

Before starting the engine, look around the machine and clean any combustibles from the

surroundings of the engine. Also, inspect if oil or water is leaking and any nuts, bolts or electric

wiring are loosened or damaged.
