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.
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.
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.
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.
