Traveling up slopes

WARNING

¡ Never exceed the machine’s stability

ground and stop the machine.

Traveling down slopes

¡ When traveling on slopes or grades,

move slowly in first gear (low speed).

¡ Do not travel down slopes in reverse.

When traveling down slopes at an angle of

15° or greater, lower the engine speed and

travel in the posture shown in the diagram

above.

¡Do not change directions or cross

slopes sideways. First return to a flat

OPERATION

Handling Rubber Crawlers

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

E4D057

Do not travel or operate the machine in the

¡ Do not let fuel, oil, salt or chemical solvents

following places :

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.

E4D056

¡ 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.

E4D058

¡ 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

E4D055

speed up lug wear.

¡ 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.

Replace the hydraulic oil regularly!

When using a hydraulic breaker, the oil deteriorates quicker than during normal digging. Be

sure to replace the hydraulic oil and return filter element.

¡ Failure to replace these in time can lead to damage to the machine and breaker’s hydraulic

systems. In order to improve the service life of the hydraulic systems, be sure to replace

the hydraulic oil and return filter element according to the following chart of the replacement

interval.

¡ Clean the suction strainer when changing the return filter element.

Tightening Torques

Nuts and Bolts (for ISO strength category 10.9)

Tighten nuts and bolts at the torques shown on the table below, unless otherwise specified in

the text.

¡ Tightening torques when mounting plastic covers differ from the values on the table below.

Consult a Takeuchi sales or service outlet. Tightening too strongly will break the cover.

¡ When replacing nuts and bolts, replace them with nuts and bolts of the same size and

standards.

¡ Tighten nuts and bolts alternately (top, bottom, left then right) or in 2 or 3 times so that they

are tightened uniformly.

Above important parts are vulnerable to aging and wear or deterioration and it is difficult to

determine the degree to which they have deteriorated on the occasion of periodic service. To

maintain their proper function at all times, therefore, replace them with new ones after using

them for a specific period of time even if no abnormality is found with the parts. If you find

abnormalities in these parts before their scheduled replacement time is reached, repair or

replace them immediately. If a hose clamp is deformed or cracked, replace it immediately.

When replacing the important parts, please contact a Takeuchi sales or service outlet .

Also check the hydraulic hoses other than the above important parts. If any abnormality is

found in them, retighten them or replace them immediately.

When replacing the hydraulic hoses, replace the O-rings and seals at the same time.

Check the fuel and hydraulic hoses according to the periodic schedule described below.

Refer to “Maintenance”.

MAINTENANCE

Walk-Around Inspection

Perform the following inspections once every day before starting the engine the first time.

WARNING

¡ Before operating, perform the walk-around inspections and make repairs immediately

should any irregularities be found.

¡ Be sure to secure the engine hood or cover when opening it. Do not open the engine

hood or cover on slopes or in strong wind.

Before starting the engine, look around the machine and lower body, clean any combustible

materials off high temperature parts of the engine, and inspect for such irregularities as oil

leakage, water leakage and looseness of nuts and bolts.

Inspecting by Opening the

Engine Hood and Covers

1. Check for any twigs, leaves, oil or other

3. Check for oil leakage from the hydraulic

combustible materials around the engine

tank, hydraulic devices, hoses and

and battery.

connections.

2. Check for oil or engine coolant water

leakage around the engine.
