Opening coolant water drain valve cap
Be sure to stop the engine, and let the coolant water
sufficiently cool down before draining it.
If the drain valve is opened before the coolant water is cooled
enough, hot water could jet out, and it could cause scalding.
Refilling or draining of engine oil
After stopping the engine, wait for 10 to 20 minutes until the
engine oil cools off. Then check the level of the engine oil, or
refill or drain the oil.
Engine oil is very hot and highly pressurized during or just after
the operation. Hot oil could blow out of the tank and can cause
scalding.
Fear of fire
Be sure to perform the periodical check of compressor oil and
oil separator.
Neglecting checks could cause overheat of the oil, resulting in
a fire.
Disposal of waste liquid, etc.
Waste liquid from the machine contains harmful material. Do not discharge it onto the ground or into
the river, lake or sea. Such material will contaminate the environment.
Be sure to use a container to hold the waste liquid from the machine.
Be sure to follow the designated regulations when disposing of oil, fuel, coolant (antifreeze), filter,
battery or other harmful materials.
