thoroughly familiarize themselves with the following sections.

All operators must be instructed on the proper functions of the excavator before

running the machine.

Learn and practice correct use of the machine controls in a safe, clear area before

operating this machine on a job site.

CAUTION

Improper operation, inspection and maintenance of this

machine can cause injury or death.

Read and understand this manual before performing any

operation, inspection or maintenance on this machine.

Always store this manual near at hand preferably on the machine itself. If it should be lost

or damaged, immediately order a new one from your Takeuchi dealer.

When transferring ownership of this machine, be sure to provide this manual to the next

owner.

Takeuchi supplies machines complying to the local regulations and standards of the

country of export. If your machine has been purchased in another country or from a

person or company of another country, it may not have the safety devices or safety

standards required for use in your country. Should you have any question about whether

your machine complies with the regulations and standards of your country, contact a

Takeuchi dealer.

Please note that the contents and diagrams included in this manual may not match your

machine exactly.

It is your responsibility to observe all pertinent laws and regulations and to follow the

manufacturer’s instructions on machine operation, inspection and maintenance.

Virtually all accidents occur as the result of a failure to observe basic safety rules and precautions.

An accident can often be avoided by recognizing potentially hazardous situations beforehand.

Read and understand all of the safety messages which explain how to prevent these accidents

from occurring. Do not operate the machine until you are sure that you have gained a proper

understanding of its operation, inspection and maintenance.

SlGNAL WORDS

Safety messages appearing in this manual and on machine decals are identified by the words

Break-in period

When the machine is new, heed the instructions below when operating the machine for the first

100 hours (as indicated on the hour meter).

Using a new machine roughly without breaking it in will lead to quicker deterioration of machine

performance and may shorten the machine’s service life.

Warm up the engine and hydraulic oil sufficiently.

Avoid heavy loads and rapid operations. Operate with a load of about 80% the maximum

load.

Do not start up, accelerate, change directions, or stop abruptly unless necessary.
