When handling coolants
After operation of the machine the coolant is of high
temperature and high pressure, and is retained inside the
engine radiator and the heater line. Direct contact of the
skin with the coolant may result in serious burns. Open the
cap of the radiator only after the engine has sufficiently
cooled and the pressure has reduced to a safe level.
Coolant contains toxic and combustible ethylene glycol,
and should be handled in a cool, well-ventilated place
only when wearing protective goggles, protective gloves,
protective clothing, and a gas mask.
Avoid inhaling airborne particles or spray from coolant. If
the substances make contact with skin or eyes that are
not protected by personal protection gear, immediately
wash the skin and eye with flowing water for 20 minutes or
longer.
When working in a place subject to airborne particles and
falling objects,
Make sure you wear a safety helmet, protective goggles
and safety shoes to prevent injury from such particles and
objects. Earplugs or earmuffs may be necessary when
working in a noisy place.
When working in places with a high level of noise
When the operator is exposed to the noise exceeding 90
dB (A) for 8 hours or longer, wear earplugs or earmuffs.

Cautions to Be Taken When Driving the Machine
· If you operate the machine with the parking brake on, it
may cause serious damage to the parking brake disk.
· Select the appropriate gear for the driving speed.
· Do not change direction when driving the machine at
max. speed as this may cause serious damage to the
transmission.
· Only drive the machine for short distances on the road.
· Make sure you fully comply with the local road traffic Driving position
regulations and legislation of your country when driving on
the road.
· Please note that the machine is wider and travels at a
lower driving speed than other vehicles on the roads.
· Pay attention to any vehicles behind your vehicle, and
allow them to overtake your vehicle safely.
· Check the following conditions before driving the machine
on the public road :
- Remove any dirt and sand from the machine.
- Empty the bucket and move it to the driving position (40~
50 cm above the ground) and fix it.
- Close the windshield. Turn the working light off.
- Wear the seat belt.
- Use the lighting devices, such as the headlights, emergency
warning light and rotating beacon, pursuant to the local
road traffic legislation.
- Pay attention to people in the vicinity of the machine.
- Do not operate the machine on roads or bridges where
the machine exceeds the weight limit.
- Familiarize yourself fully with the width, length and height
of the machine.
- Check the tire pressure.
- When traveling for a long distance, stop the machine
after every 40 km or on an hourly basis, and take a
break.
- Check the level of fuel and coolant.
- Never shift the gear to the neutral position when driving
down a slope.
- Changing direction when operating the machine on a
slope is dangerous.
- Do not drive on a slope of 30˚ or more.
- Drive slowly when traveling the machine on rough terrain
or moving over obstacles.
- Install chains on the tires when operating the machine
on slippery roads covered with snow or rainwater, and do
not attempt to start, stop or turn the machine suddenly.
- Be sure to avoid any obstacles when traveling the
machine on paths.

Regular lubrication (during storage)
· Breaking the lubrication film on parts may cause
abnormal abrasion during the next operation.
· Start up the engine once a month, perform all of the
functions, and apply lubrication oil to every part.
· Check the level of the engine oil and coolant when
starting the engine up, and top them up if necessary.
· Thoroughly wipe off any rust-proofing oil from the
cylinder and piston rod.
· Sufficiently warm up the engine after starting the engine
and repeat the operation of the attachments several
times to wear in the parts sufficiently.
· Fully charge and store the battery.
· Store the battery separately for a long period of time
under extremely cold weather conditions.
· Check the tire pressure.
· The machine shall not be lubricated manually while it
is in motion where application of the lubricant may
expose persons to injury.

(18) HEST (High exhaust system temperature) warning lamp
① This warning lamp indicates, when illuminated, that exhaust
temperatures are high due to exhaust system cleaning.
② The lamp will also illuminate during a manual exhaust system
cleaning.
③ When this lamp is illuminated, be sure the exhaust pipe outlet
7609A3CD53 is not directed at any surface or material that can melt, burn, or
explode.
When this lamp is illuminated, the exhaust gas temperature
could reach 800

[1500˚F],
], which is hot enough to ignite or
melt common materials, and to burn people.
※ The lamp does not signify the need for any kind of equipment
or engine service; It merely alerts the equipment operator to
high exhaust temperatures. It will be common for the lamp to
illuminate on and off during normal equipment operation as the
engine completes exhaust system cleaning.

9. OPERATION IN THE SPECIAL WORK SITES
1) OPERATION THE MACHINE A COLD WEATHER
(1) Use proper engine oil and fuel for the weather.
(2) Fill the required amount of antifreeze in the cool-
ant.
50 C
(3) Refer to the starting engine in cold weather.
Start the engine and extend the warming-up
operation.
(4) Be sure to open the heater cock when using the
heater.
(5) Always keep the battery completely charged.
※ Discharged batteries will freeze more easily
than fully charged.
(6) Clean the machine and park on the wood plates. 955TM4OP16
2) OPERATION IN SANDY OR DUSTY WORK SITES

hydraulic circuit by tightly closing breather cap of
hydraulic oil tank. Replace hydraulic oil filter fre-
quently.
(5) Keep all lubricated part, such as pins and bush-
ings, clean at all times.
(6) If the air conditioner and heater filters clogged,
the heating or cooling capacity will drop. Clean
or replace the filters more frequently.
