OPERATION

Starting and Stopping the Engine

IMPORTANT: Do not start the engine
before the power mode lamp (L) lights.

Check that the power mode lamp (L) is
lit.

All the warning lamps flash and an
alarm is sounded for 2 seconds. The
meters also start functioning. After 2
seconds, only the battery charge
warning lamp (4) and engine oil
pressure / coolant level warning lamp
(2) flash, and the other lamps turn off.

Turn the light switch to check that the
boom light, front light, side lights, tail
lights and meter light turn on.

Check the fuel level.

If a lamp does not light or the alarm is not
sounded, the bulb may be burnt out or a wire
may be damaged. Contact a Takeuchi sales
or service outlet for repairs.

Warming Up the Machine
(Hydraulic Oil)

WARNING

Operating the working equipment without
warming up the machine (hydraulic oil)
is dangerous, as response will be slow
and the equipment may move in
unexpected ways and safety devices may
not operate properly. Be sure to
sufficiently warm up the machine.

IMPORTANT: Do not operate the levers
suddenly when the hydraulic oil
temperature is below 20

C (68

F). The

proper hydraulic oil temperature during
operation is 50 to 80

C (122 to 176

F), but

if operations must be performed at lower
temperatures, heat up the hydraulic oil
to at least 20

C (68

F).

Normal Warm-up

1. Run the engine at medium speed (FC

mode) for about 5 minutes with no load.

2. Fully lower the safety lock lever to

disengage the lock and lift the bucket from
the ground.

3. Extend and retract each of the cylinders

several times with no load.

4. Slew slowly left and right several times.

Inspection After Warm-up

After warming up the engine and hydraulic
oil, perform the checks and inspections
described below, and repair if there is a
problem.

1. Check that the warning lamps and meters

are as follows:

Are all the warning lamps off?

Is the water temperature gauge’s
needle within the green range?

2. Check that there are no irregularities in

the exhaust color, sound and vibrations.

3. Raise the safety lock lever to engage the

lock and check that the boom swing pedal,
operating and travel levers are locked.

5. Travel slowly forward and backward

several times.

Warming Up in Cold Weather
1. Perform the normal warm-up procedure.

2. Set the bucket cylinder at the stroke end

and keep it there.
Do not do this for more than 30 seconds.

3. Repeat step 2 until the bucket operating

speed is normal.

OPERATION

Machine Operation

2. Fully lower the safety lock lever to

disengage the lock.

3. Fold the hoe attachment and lower it to

30 to 40 cm(12 to 16 in.) above the ground.

4. Lift the dozer blade.
5. Operate the left and right travel levers as

described below.

When the dozer blade is in front of the
operator’s seat:

To move forward:
Tilt the levers forward.

To move backward:
Tilt the levers backward.

Operating the Travel Levers

WARNING

Never allow anyone to enter the
slewing (swing) radius and machine
path.

Signal your intention to move by
sounding the horn.

There are blind spots to the rear of the
machine.
If necessary, swing the cab around
before backing up to check that the
area is safe and clear.

Before operating the travel levers,
check to make sure that the dozer blade
is to the front of the operator’s seat.
BE AWARE that when the dozer blade
is to the rear of the operator’s seat, the
travel levers operate in the opposite
direction to when the dozer blade is in
the front.

Remove any obstacles in the
machine’s path.

Traveling Forward and Backward

1. Increase the engine speed.

Traveling in 2nd (High) Speed

WARNING

When a load greater than a set value is
applied during 2nd speed (high speed)
travel, the speed will automatically slow
down by switching to 1st speed (low
speed). Thereafter, when the load
becomes lighter, the speed will increase
by returning to 2nd speed (high speed).
Exercise due caution since the travel
speed changes automatically.

Press the travel speed switch on the right
travel lever to switch to 2nd (high) speed,
and press it again to return to 1st speed (low
speed).

Neutral

Pivot Turn

WARNING

Note that when the bucket is operated
while making a right pivot turn (i.e., when
only the left crawler is turning), the speed
of the pivot turn may suddenly increase.

Turning to the left when stopped:

To turn forward to the left:
Tilt the right lever forward.

To turn backward to the left:
Tilt the right lever backward.

To turn to the right, operate the left lever in
the same way.

Turning to the left while traveling:

To turn left while traveling forward:
Set the left lever to neutral.

To turn left while traveling backward:
Set the left lever to neutral.

To turn to the right while traveling, operate
the right lever in the same way.

WARNING

Park the machine on firm, level ground
and apply the parking device. If you
must park on a slope or incline, block
the machine securely to prevent
movement.

If any controls should be touched
accidentally when the safety lock lever
is lowered, the machine will move
suddenly, and cause serious injury or
death.

Note that the dozer blade control is not
locked, even when the safety lock lever
is set to the lock position. Do not touch
this control accidentally.

CAUTION

Never bring the machine to a sudden stop
except in the case of a true emergency.
Stop as gently as possible.

1. Slowly set the left and right travel levers

to the neutral position. The machine stops.

OPERATION

Operating Procedures

Be Gentle on the Hydraulic Cylinders

Do not extend the hydraulic cylinders to the
stroke ends. Operate them with leeway.

Do not support the machine body with the
hoe attachment as it is lowering with the arm
cylinder fully extended. Doing so
concentrates the load on the arm cylinder
and could damage the arm cylinder.

Do not Drive Piles with the Bucket or
Dig with it Using Shock Force

Doing so will shorten the service life of the
hoe attachment. Use hydraulic force to dig.

Prohibited Operations

WARNING

Do not operate on base rock (hard or
soft).

Do not slew (swing) while traveling. If
you must operate the hoe attachment
while traveling, operate at speeds slow
enough so you have complete control
at all times.

Do not perform breaking or leveling
operations using slew force

Do not break down walls or level ground
using slew force. Also, do not dig the bucket
teeth into the ground during slewing. Doing
so will damage the hoe attachment.

Do not Dig while Traveling

Do not dig the bucket into the ground and
use the traveling force to dig.

OPERATION

Operating Procedures

Do not Perform Operations Using the
Machine’s Dropping Force

Putting excessive strain on the machine will
shorten its service life. Use the hydraulic
force of the cylinders and always dig with
shallow, long strokes.

Digging Base Rock

For hard base rock, break the rock up into
small pieces with a breaker, etc., before
digging. This prevents damage to the
machine and is thus more economical in the
end.

Caution on Exposing the Dozer Blade to
Shocks

Hitting the dozer blade against rocks, etc.,
could damage the dozer blade or the blade
cylinder.

Caution on Folding the Hoe Attachment

Be careful not to hit the bucket or dozer blade
when folding the hoe attachment.

Do not use the Dozer Blade as an Outrigger
