SAFETY

PRECAUTIONS WHEN PREPARING

Check the strength of the bridge

Always keep the machine clean

When traveling over a bridge or a structure,

check the permissible load. If the strength is

insufficient, reinforce the bridge or the

structure.

• Wipe off any oil, grease, mud, snow or ice,

to prevent accidents due to slipping.

• Remove all loose objects and unnecessary

devices from the machine.

• Remove any dirt, oil or grease from the

engine area to prevent fires.

• Clean around the operator’s seat and

remove any unnecessary object from the

machine.

and avoid starting, stopping or changing

directions abruptly. Otherwise, the working

equipment may come in contact with the

ground, causing the machine to lose its

balance and get damaged or to damage

the structures in the surrounding area.

• Travel with the dozer blade raised, the hoe

attachment folded as shown on the figure

above, and the bucket raised 30 to 40 cm

(12 to 16 in.) above the ground.

SAFETY

PRECAUTIONS WHEN OPERATING

Cautions on traveling on slopes

When traveling on slopes or grades, be

careful that the machine does not tip (roll)

over or slide.

• Never travel on slopes that are too steep

for the machine to maintain its stability.

Note that in reality, the machine’s

performance decreases on slopes due to

its poor working condition.

• Do not change directions on slopes or

traverse slopes. First return to a flat

surface, and then take an alternative path.

• The machine may slip sideways even on a

slight slope if the ground is covered with

grass or dead leaves, or when traveling on

a wet metal plate or frozen surfaces. Make

sure the machine is never positioned

sideways on slopes.

• If the machine is stalled on the slope,

return each operating lever to the neutral

position before restarting the engine.

• When climbing a hill, keep the operator’s

seat facing the hillside. When descending a

hill, keep the operator’s seat facing the

downhill direction. In either case, travel

must be done while paying attention to the

ground in front of the machine.

• When traveling on slopes, lower the bucket

to a height of 20 to 30 cm (8 to 12 in.)

above the ground. When climbing a steep

slope, extend the hoe attachment to the

front. In emergencies, lower the bucket to

the ground and stop the machine.

• When traveling on slopes or grades, drive

slowly in 1st (low) speed. When

descending a slope, slow down the engine

speed.

• Do not descend slopes in reverse.

1-17

SAFETY

PRECAUTIONS WHEN OPERATING

Be careful with flying objects

Cautions when towing

This machine is not equipped with protective

equipment to protect the operator from flying

objects. Do not use this machine in places

where there are risks of the operator being

hit by flying objects.

When towing, serious injury or death could

result, if performed incorrectly or the wire

rope being used is inappropriate or not

properly inspected.

• It becomes dangerous if the wire rope

breaks or becomes disengaged. Use a

wire rope appropriate for the required

tractive force.

• Do not use a wire rope that is kinked,

twisted or otherwise damaged.

• Do not apply heavy loads abruptly to the

wire rope.

• Wear safety gloves when handling the wire

rope.

• Make sure there is an operator on the

machine being towed as well as on the

machine that is towing.

• Never tow on slopes.

• Do not let anyone come near to the wire

rope while towing.

Refer to “Towing” for further instructions.

SAFETY

PRECAUTIONS WHEN STOPPING

PRECAUTIONS WHEN

STOPPING

Park safely

• Before leaving the machine, do the

followings:

1. Lower the bucket and the dozer blade to

the ground.

2. Raise the safety lock lever to the locked

position.

• Park the machine on a flat, rigid and safe

3. Stop the engine and remove the starter

key.

4. Lock the cab and covers and take the

key with you.

If you must park on a slope or incline, park

the machine securely and block the

movement of the machine.

• When parking on a street, use barriers,

caution signs, lights, etc., so that the

machine can easily be seen even at night

to avoid collision with other vehicles.

SAFETY

PRECAUTIONS WHEN TRANSPORTING

• Chock the tracks and secure the machine

PRECAUTIONS WHEN

to the truck bed with wire rope or chain.

TRANSPORTING

Load/unload the machine safely

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 the ramps of adequate strength

and size to the truck bed. The slope of the

ramps must not exceed 15°. If the rumps

are bowed down too low, support them

with poles or blocks.

• Never use the working equipment to load

or unload the machine. Doing so may

result in tipping over or falling down of the

machine.

• Keep the truck bed and loading ramps

clean of oil, soil, ice, snow, and other

materials to prevent the machine from

sliding sideways. Clean the crawlers.

• Chock the transporter wheels to prevent

movement.

• When being loaded or unloaded, travel

slowly in 1st (low) gear by following the

signal from the signal person.

• Never change courses on the ramps.

• Do not slew/swing on the ramps. The

machine may tip over.

• When slewing/swinging on the truck bed,

do it slowly as the footing should be

unstable.

• Lock the cab door after being loaded, if

applicable. Otherwise, the door may open

during transport.
