OPERATION

HANDLING TIRES

Tires are weak in strength due to the material

they are made of. Be sure to observe the

prohibitions and precautions below to

prevent the tires from being damaged or

coming off.

PROHIBITIONS

Do not travel or operate the machine in the

following places:

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

get on the tires. These substances may

corrode the metal wheels and tires,

resulting in rust or peeling. If you find any of

these on the tire, immediately wipe if off

and clean the tire with water.

• Traveling or slewing on crushed rock,

extremely rough hard rock, steel beams,

scrap iron or near the edges of steel plates

will cause damage to the tires.

• The treads will show irregular wear or will

be damaged, if the machine travels on

recently paved asphalt road, ground

around a bonfire or hot iron sheets under

the blazing sun.

• Do not move earth in places where the

tires may slip. Doing so may speed up

tread wear.

• Traveling on riverbeds or places where

there are many boulders may cause the

stones to get caught and damage the tires

or make the tires come off.

• Do not use the machine on the seashore.

The salt may corrode the metal wheels.

OPERATION

HANDLING TIRES

PRECAUTIONS

Observe the following precautions when

operating the machine:

• Tires are not very stable. Be very careful

when slewing sideways.

• Do not turn the undercarriage with the front

of the machine body lifted using the hoe

attachment (the upperstructure is not

turned). Doing so will twist the tires with the

load concentrated on a single point on the

tire, causing rapid damage to the tires.

• Avoid changing courses abruptly whenever

possible. Doing so may wear or damage

the tires.

• Avoid falling of the machine that may

expose the tires to strong shocks.

• Salt, potassium chloride, ammonium

sulfate, potassium sulfate and triple

superphosphate can damage the tires. If

any of these substances gets on the tires,

wash if off thoroughly with water.

• Do not let the sides of the tires rub against

concrete or walls.

• Do not let the bucket hit the tires and

damage them.

• Be especially careful on snowy or frozen

surfaces in winter, as the tires easily slip in

such conditions.

• Use tires at temperatures between -25°C

to +55°C (-14°F to 131°F).

• When storing the tires for long periods of

time (three months or more), do so indoors

in a place not exposed to direct sunlight or

rain.

TRANSPORT

LOADING AND UNLOADING

The machine may roll or tip over or fall

while being loaded or unloaded. Take the

following precautions:

• Select a firm, level surface and keep

sufficient distance from road shoulders.

• Secure ramps of adequate strength and

size to the truck bed. The slope of the

ramps must not exceed 15°.

switch. If the machine is operated on

such roads with these switches turned

on, the engine speed may increase,

causing the machine to travel

unexpectedly rapidly (for machines with

the deceleration and auto-deceleration

switches).

• When being loaded or unloaded, travel

slowly in low gear by following the

signal from the signal person.

• Never change courses on the ramp.

• Do not slew on the ramp. The machine

may tip over.

• When slewing on the truck bed, do it

slowly as the footing should be

unstable.

When loading or unloading the machine, be

sure to use ramps or a platform and follow

the procedure below.
