Clean them thoroughly with nonflammable solvent
before welding or flame cutting them.
Precautions for Handling Accumulator and Gas
Damper
High-pressure nitrogen gas is sealed in the accumulator and
the gas damper. Inappropriate handling may cause explosion,
possibly resulting in serious injury or death.


Do not disassemble the unit.

Keep the units away from open flames and fire.

Do not bore a hole, do not cut by torch.

Avoid giving shocks by hitting or rolling the unit.

Before disposing the unit, sealed gas must be released.
Consult your nearest authorized dealer.
Precautions for Diesel Exhaust Fluid (DEF)

Diesel exhaust fluid (DEF), commonly referred to as
AdBlue®, is an aqueous urea solution used as a consumable
in selective catalytic reduction (SCR) to lower NOx
concentration in the exhaust emissions from the engine.
It is a non-flammable and non-hazardous solution, and
harmful effects are not expected under normal conditions
of use.

In case of a fire, DEF/AdBlue® would decompose and
generate ammonia gas when heated to 160 °C (320 °F) or
higher.
Ammonia gas may cause lung injury and potentially is fatal
if inhaled. It is a corrosive gas and the liquefied gas can
cause frostbite and corrosive injury to eyes and skin.
In case of contact, immediately flush skin with plenty of
water at least 15 minutes while removing contaminated
clothing. Get medical attention if symptoms occur.

DEF/AdBlue® is corrosive to steel, aluminium, copper and
brass, etc. If DEF/AdBlue® is spilled on your vehicle, wipe off
and rinse with water.

For the handling of DEF/AdBlue®, follow handling
precautions on Material Safety Data Sheet. Have suitable
emergency equipment for fires, spills and leaks readily
available. Practice good housekeeping. Maintain handling
equipment. Comply with applicable regulations.
