Operating Procedures

Pay Attention to the Dozer Blade when
Digging

When digging deeply with the dozer blade
positioned at the front, be careful that the
boom cylinder and bucket do not hit the dozer
blade.
Operate with the dozer blade at the rear
whenever possible.

Caution on Digging Down with the Dozer
Blade

This dozer blade is designed for simple earth
pushing. Do not dig down deeply with the
dozer blade. Doing so could damage the
dozer blade and lower body.

Cautions on Operating

Cautions on Traveling

Traveling over obstacles (rocks, stumps, etc.)
may subject the body to strong shocks and
result in damage. Avoid traveling over
obstacles whenever possible. If you must do
so, keep the hoe attachment near the ground,
travel at low speed, and go over the obstacle
at the center of the crawler.

Cautions on Traveling in 2nd (High)
Speed

On uneven ground, travel at low speed
and avoid accelerating, stopping or
changing directions abruptly.

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.

When traveling in 2nd speed, do so with
the dozer blade at the front.

Cautions on Use in Water

If you leave water at a sharp angle, the rear
of the machine may be submerged, exposing
the radiator fan to water and damaging them.
Do not let the rear of the machine get
submerged.

Allowable water depth.
In water, only use the machine up to a
depth at which the water comes up to the
middle of the carrier roller (1).

When greasing places used under water
for long periods of time, apply enough
grease so that the old grease is expelled.

Never submerge the slew bearing or main
body in water or sand. If the slew bearing
or main body should get submerged,
contact a Takeuchi sales or service outlet
for inspection.

Cautions on Traveling on Slopes

WARNING

Never exceed the machine’s stability
capabilities (maximum gradeability -
35

, lateral tipping angle - 15

). Also

note that when actual working area
conditions are poor the machine’s
stability capabilities may be lower.

When traveling on slopes or grades,
lower the bucket to a height of 20 to 30
cm (8 to 12 in.) off the ground. In
emergencies, lower the bucket to the
ground and stop the machine.

When traveling on slopes or grades,
move slowly in first gear (low speed).

Do not travel down slopes in reverse.

Do not change directions or cross
slopes sideways. First return to a flat
surface then redirect the machine.

On grass, dead leaves, wet metal or
frozen surfaces, the machine may slide
sideways even on very gentle slopes.
Make sure the machine never faces
sideways with respect to the slope.

Operating Procedures

Braking when traveling down slopes

When traveling down slopes, the brakes are
applied automatically when the travel levers
are returned to the neutral position.

If the crawlers slip

If the crawlers slip while traveling up a slope,
use the pulling force of the arm to climb the
slope.

If the engine stops

If the engine stops when traveling down a
slope, set the travel levers to the neutral
position, stop the machine, then start the
engine.

Traveling Posture

1. Slew the bucket to the side which is stuck.
2. Set the arm and boom to an angle of 90

to 110

3. Press the bottom of the bucket (not the

teeth) against the ground.

4. Place a plank, etc., under the lifted crawler.
5. Lift the bucket and slowly move out of the

mud.

If both crawlers are stuck
1. Perform steps 1 to 4 above for both

crawlers.

2. Dig the bucket into the ground in front of

the machine.

3. Pull with the arm and travel forward

simultaneously to slowly move out of the
mud.

Do not open the door while traveling on
slopes

Opening the door while traveling on slopes
is dangerous, as the force required to open
and close the door changes abruptly. Always
keep the door closed when traveling on
slopes.

OPERATION

Operating Procedures

Operations Possible with this
Machine

Excavating

1. Set the dozer blade on the side opposite

the side you want to dig on.

2. Use the arm and bucket and dig with

shallow, long strokes. The digging force
is strongest when the boom and arm angle
is 80 to 120

. Use this angle for effective

digging.

Digging Ditches

Mount a bucket suited for digging ditches and
set the crawlers parallel to the ditch to be
dug for greater efficiency.
When digging wide ditches, dig the sides first,
the center later.

Digging Side Ditches

Use the boom swing function to dig side
ditches as shown in the diagram.

Loading

When loading dirt in a truck, starting from
the back of the truck’s bed makes for easier
loading and increases the amount of dirt that
can be loaded.
Also, use a small slewing angle for greater
efficiency.

Handling in Cold Weather

Cautions after Completing
Operations

Heed the following in order to prevent dirt,
water, or other objects stuck on the machine
as well as the lower body from freezing:

Remove any dirt or water from the body.
In particular, water droplets on the
hydraulic cylinder rod surfaces could
freeze, and if dirt enters into the seals
along with this, the seals could break.

Park the machine on a dry, hard surface.
If no appropriate place can be found, put
boards down and park the machine on
them.

Drain any water from the fuel tank to
prevent freezing.
Refer to page 118 “Draining the Fuel
Tank”.

prevent decreased battery

performance, place a cover over the
battery or remove it from the machine and
store it in a warm place.
Also add battery fluid before starting the
next morning. If battery fluid is added after
completing operations, the distilled water
may not mix, resulting in freezing.

After Cold Weather is Over

Perform the following after cold weather is
over:

Change the fuel and the oils for the
different devices with those specified on
the Fuel and Lubricant Chart.
Refer to page 98 “Fuel and Lubricant
Chart”.

When using one-season type antifreeze
coolant, completely drain the antifreeze
coolant, carefully clean the inside of the
coolant system, then add tap water.
Refer to page 124 “Cleaning the Engine
Cooling System”.

Preparing for Cold Weather

In cold weather, it may be difficult to start the
engine and the coolant may freeze. Make
the preparations described below.

Changing the Fuel and Lubricant
Change the fuel, hydraulic oil and engine oil
to types suited for cold conditions.
Refer to page 98 “Fuel and Lubricant Chart”.

Engine Coolant

WARNING

The coolant is combustible. Keep flames
away.

Use long-life coolant (antifreeze) and tap
water for the engine coolant.
Supplement: New machines are delivered
with JIS Type 2 long-life coolant (antifreeze)
at a concentration of 50%.
Refer to page 98 “Fuel and Lubricant Chart”.

Battery
As the temperature drops, the battery
performance decreases.
Inspect the battery. If the charge is low,
contact a Takeuchi sales or service outlet to
have the battery charged.
Refer to page 117 “Inspecting the Battery
Fluid Level and Replenishing”.

OPERATION

Handling Rubber Crawlers

Do not let fuel, oil, salt or chemical solvents
get on the crawlers. These substances
may corrode the couplings of the crawlers’
metal cores, resulting in rust or peeling. If
these substances should get on the
crawlers, wipe them off immediately using
water.

Traveling on roads directly after asphalting
or on hot surfaces such as over fires or
on iron sheets under strong sunlight may
result in irregular wear or damage of the
lugs.

Do not move earth in places where the
rubber crawlers may slip. Doing so may
speed up lug wear.

Rubber crawlers have an inherent weakness
due to their use of rubber. Be sure to heed
the prohibitions and cautions below so as to
prevent damage to the crawlers and crawler
slippage.

Prohibited Actions

Do not travel or operate the machine in the
following places:

Traveling or slewing on broken stone,
jagged base rock, iron rods, iron scraps
or the edges of iron sheets may damage
or cut the crawlers.

Traveling on riverbeds or places with many
soft rocks may cause the crawlers to slip
off or be damaged due to rocks getting
stuck in them.

Do not use on the seashore. The salt may
corrode the metal cores.

OPERATION

Handling Rubber Crawlers

Cautions

Heed the following cautions when operating
the machine:

Do not turn the undercarriage with the front
of the machine body lifted using the hoe
attachment and the upperstructure left in
this posture. Doing so will twist the crawler
with the load concentrated on a single
point on the crawler belt, rapidly leading
to damage.

Avoid changing course abruptly and
spinning on concrete surfaces whenever
possible.
Doing so may wear or damage the rubber
crawlers.

Avoid drops that may expose the rubber
crawlers to strong shocks.

Salt, potassium chloride, ammonium
sulfate, potassium sulfate, and triple
superphosphate of lime can damage the
crawler belts. If any of these substances
should get on the crawler belts, wash them
off thoroughly with water.

Do not let the sides of the rubber crawlers
rub against concrete or walls.

Do not damage the rubber crawlers by
hitting the bucket against them.

Be especially careful in the winter on
snowy or frozen surfaces as the crawler
belts tend to slip.

L4D013

Use rubber crawler belts at temperatures
between –25

C to +55

C (–14

F to

131

F).

When storing the rubber crawlers for long
periods of time (3 months or more), do so
indoors in a place not exposed to direct
sunlight or rain.

Rubber crawler belts are not as stable as
steel crawler belts since the entire lug is
rubber. Be very careful when slewing and
swinging sideways.

Preventing the Rubber Crawlers from
Slipping Off
Heed the following in order to prevent the
rubber crawlers from slipping off:

Always keep the crawlers at the proper
tension.

When traveling up large cobblestone or
rock steps (20 cm (8 in.) or greater), climb
up the step at a direct angle and do not
change course on top of the step.

TRANSPORT

Loading and Unloading
