■ Designated operations

Use this machine primarily for the following

operations:

¡ Excavating

¡ Digging ditches

¡ Digging side ditches

¡ Leveling

¡ Loading

■ Features

¡ Short pitch rubber crawler

¡ Low engine noise and exhaust emissions

¡ Fast working speed and low-shock working equipment

¡ Excellent stability thanks to a low center of gravity

■ Break-in period

When 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.

Maintenance Precautions

Have a Takeuchi service agent

repair welding cracks or other

damage

Ask a Takeuchi service agent to repair any

welding problems which are detected. If not

feasible, make sure the welding is done by a

qualified person in a properly equipped

workplace.

Checks after maintenance

¡ Gradually raise the engine speed from a

low idle to maximum speed and check that

no oil or water is leaking from serviced

parts.

¡Move the controls and check that the

machine is operating properly.

Disposing of wastes

¡ Funnel spent fluids from the machine into

containers. Disposing of fluids improperly

destroys the environment.

¡ Follow the prescribed regulations when

disposing of oil, fuel, engine coolant,

refrigerant, solvents, filters, batteries or

other harmful substances.
