Description and Operation (Continued)
When spraying the substances with the solvent,
such as oil paint, adhesive agent, ensure that the
ventilation conditions of the field are good, if the
air ventilation is poor, use the gas mask.
The heating and combustion operation are
performed only under the manufacturer’s special
guide.
Suspended Load
Warning: it is prohibited to piece together
the hoisting device temporarily.
When the heavy article is raised or suspended, there
is dangerous. Never operate under the objects
without being supported, suspended or raised, such
as the suspended engine.
Ensure the equipment such as the hoisting devices
of hoisting jack, lifter, axle stand and assist strap to
be intact, and regularly inspect them.
Sealing on Vehicle Base
Refer to the Section Corrosion Preventing Material.
Welding
Refer to Fire Prevention, Electric Shock and High
Pressure Cylinder.
The welding procedures include (resistance welding)
spot welding, arc welding and gas welding.
Resistance Welding
The spot welding will release plentiful high speed
melting metal grains, so pay attention to protect
skins and eyes.
Arc Welding
During the arc welding, there has a great amount of
ultraviolet radiation, and the ultraviolet radiation
will damage the skins and eyes of the operators and
the nearby staff. The gas shielded welding is
extremely dangerous, so the personal protective
clothes should be wore, and the protective screen
should be used to protect other people.
The contact glasses wearer is suggested to wear
the normal glasses when using the arc welding.
The arc light will release microwave which will
make the space between the cornea and the
glasses of the contact glasses wearer dry, even
lead to blindness.
There will be metal splashing during the use of the
arc welding, so the correct protection measures for
the eye and the skin should be taken.
When the welding core or its protective layer is
polluted, the heat quantity of welding arc light will
enable the metal melting pond to produce smog and
gases during the welding, the gases may have
poison, thus avoiding inhaling the gases. The toxic
gases within working area muste be eliminated,
especially when the air circulation is poor and the
large quantity of welding is known in advance. The
oxygen mask should be worn while welding is
performed under the special cases or in the small
section.
Gas Welding (Gas Cutting)
The oxuacetylene furnace will be used for cutting
during welding and cutting, be cautious to the
leakage of the gases, and carelessness will lead to
combustion and explosion.
When the gas welding is adopted, the metal
splashes will be produced, thus the proper
protective measures for the skins and the eyes must
be taken.
The welding flame is much glared, so the eyes must
be protected. As the ultraviolet light produced by
the gas welding is less than that produced by the arc
welding, the protective glasses can be used.
When the gas welding is adopted, some harmful
gases may be produced, but the harmful gases are
produced by the welding coating, especially the
cutting damaged parts. Avoid inhaling the gases.
During the braze welding, the metal in the braze
welding bars will produce harmful gases, and it is
extremely dangerous if the braze welding bars have
cadmium. Be extremely cautious to avoid inhaling
the harmful gases when the circumstances happen,
and ask for help from specialists.
The special preventive measures should be taken
before any welding or cutting in the automobile
with inflammable materials (such as the fuel which
is volatilized or boiled away from the oil tank).
Warning Signs on Vehicle
The warning signs will be seen on the various
automobile components.
It is prohibited to move these signs. The owner of
the vehicle or the maintenance staff should pay
attention to the warning signs.
The marks of most commonly seen warnings are as
follows and are attached with notes.
