General Precautions

Precautions on Safety

WARNING

Heed the following when removing or installing an attachment or option:

Consult with a Takeuchi dealer before installing optional attachments.

Do not use attachments that have not been approved by Takeuchi or a Takeuchi
dealer. Doing so may compromise safety or adversely affect the machine’s operation
or service life.

Takeuchi will not be held responsible for any injuries, accidents or damage to
products caused by the use of a non-approved attachment.

Choose a flat, hard surface to perform the operations. Also make sure there is enough
light and good ventilation.

Clean the area, remove any articles that may get in the way or be dangerous, and
remove any spilt oil or grease.

When performing lifting operations, determine a person to lead the operations and
always follow that person’s instructions.
• Follow the leader’s instructions on operating methods and procedures.
• Determine a signal leader and heed this person’s signals.

When removing or installing the hoe attachment, place it in a stable position so that
it does not tip over.

Due to the risk of loads falling and/or hitting people, do not allow unauthorized
personnel in the work area.

Use the crane to carry heavy objects (25 kg (55 lb.) or greater).

When removing heavy parts, be sure to prop them up before removing them. When
lifting them with a crane, be careful to balance them properly.

Operating with loads suspended with the crane is dangerous. Place loads on a
stand and check for safety.

When attaching the boom or arm, failure to follow proper procedures could result in
serious damage. Consult with a Takeuchi dealer beforehand.

Precautions on Installing Attachments

After replacing optional attachments or other special attachments, test-run them, then inspect
the hydraulic oil level and add oil if necessary.
In addition, consult with a Takeuchi dealer for details of removal and installation procedures.

OPTIONS

183

General Precautions

Precautions on Operating Attachments

WARNING

Long attachments reduce machine stability. When traveling down steep slopes or
slewing on slopes, the machine may loose its balance and tip over.
The following operations are particularly dangerous. Do not perform them.

When heavy attachments are installed, the overslew (the distance from where the
operation to stop slewing is performed until slewing stops completely) increases
and mistakes in judgment may result in the attachment hitting surrounding objects.
Allow for plenty of room between the attachment and obstacles.
In addition, the natural drop (the gradual dropping of the attachment under its own
weight when it is stopped in midair) also increases when heavy attachments are
installed.

The machine can tip over more easily in the lateral direction than in the longitudinal
direction.
• Do not slew (swing) sideways with excessive weight at the front. In particular do

not slew sideways on slopes.

• The front is heavier for machines equipped with breakers, crushers or telescopic

arms than for machines equipped with the standard bucket. Do not operate such
machines sideways, especially with the digging arm (boom) downhill.

When a long arm or a telescopic arm is installed, the operating range suddenly
increases and mistakes in judgment may result in the attachment hitting surrounding
objects. Allow for plenty of room between the attachment and obstacles.

Biodegradable Oil

Biodegradable oil

Biodegradable oil is a new type of hydraulic oil that is decomposed into carbon dioxide and
water by microorganisms in the soil and water. It is highly safe for living organisms and offers
advantages in terms of environmental protection.

Recommended biodegradable oil: Mobile EAL Envirosyn 46H (an ester synthetic oil).
When replacing the hydraulic oil with biodegradable oil, use the above or an equivalent oil.
Note that other oils, even other brands of ester synthetic oils, may damage O-rings, packings
and seals. Takeuchi products shipped with the optional biodegradable oil are shipped with
the above brand of oil.

When switching from a mineral oil to a biodegradable oil, the parking brake torque decreases
by about 30%.

Replacing the hydraulic oil with biodegradable oil

Mixing mineral oil with biodegradable oil will result in a decrease of the hydraulic oil’s
performance as well as a decrease in biodegradability and safety. The hydraulic oil system
must be flushed as described below before supplying the biodegradable oil. This operation is
dangerous and requires experience. Have it performed by a Takeuchi sales or service outlet.

Flushing

To be performed by a Takeuchi sales or service outlet

1. Drain the hydraulic oil (mineral oil) from the hydraulic tank and clean the inside of the tank

and suction strainer. (Refer to the section on replacing the hydraulic oil and cleaning the
suction strainer.)

2. Remove the cylinder hoses and drain the hydraulic oil (mineral oil) from inside the cylinders.
3. Supply new biodegradable oil to the hydraulic tank.
4. Bleed the air from the hydraulic pump, control valve, slew motor and cylinders.
5. Operate the hydraulic devices for 30 minutes.
6. Drain the biodegradable oil from the tank and cylinders.
7. Replace the hydraulic oil return filter with a new filter.
8. Repeat steps 3 and 4.
9. Operate the hydraulic devices for 30 minutes.
10. Drain the biodegradable oil from the tank and cylinders.
11. Repeat steps 3 and 4.
12. Operate the hydraulic devices for 1 hour.
13. Drain the biodegradable oil from the tank and cylinders.
14. Replace the return filter with a new filter.
15. Repeat steps 3 and 4.
16. Operate the hydraulic devices, then check for oil leakage.

There is no need to flush the hydraulic oil system when switching from biodegradable to
mineral hydraulic oil.

WARNING

Excavator must be equipped with
boom swing stopper.

Use caution when operating.
Telescopic arm reduces craning
capacity and bucket may come into
contact with excavator. Excavator may
become unstable when operating over
the side or with boom swing.

SAE heaped capacity of bucket
installed on telescopic arm must not
exceed 0.201 m

(7.1 cu.ft.).

Do not install hydraulic breaker,
compactor or similar attachment on
telescopic arm.

Telescopic Arm

Caution on Using the Arm

The machine may loose balance and tip
over when slewing or operating the
attachment on slopes. It is particularly
dangerous to slew with the arm extended
on the bucket full. Never do so.

NEVER slew suddenly or stop slewing
suddenly with the arm extended. Doing
so may damage the arm.

Telescopic Arm

Do not put the arm under water. Also avoid
moisture when storing.

The arm pressing speed is slow when
pressing the arm while simultaneously
extending it, but the arm pressing speed
suddenly comes faster when the arm
extending operation is stopped or the
cylinder end is reached. Be careful not to
hit surrounding objects.

Do not operate on base rock or hard soils,
as doing so may shorten the arm’s service
life.

Do not change directions with machine
lifted by pressing the bucket pressed
against the ground. Doing so may damage
the arm.

When dumping soil from the bucket or
shaking the bucket to remove the
remaining soil, do so with the arm retracted
to protect the arm extension/retraction
section.
