Fire Extinguisher
Have a fire extinguisher-type BC and 1.5KG minimum
capacity-on rear overhead guard leg with latch and
know how to use it. Inspect and have it serviced as
recommended on its instruction plate.
Ether
Ether is poisonous and flammable.
Breathing ether vapors or repeated contact of ether with
skin can cause personal injury.
Use ether only in well-ventilated areas.
Do not smoke while changing ether cylinders.
Use ether with care to avoid fires.
Do not store replacement ether cylinders in living areas
or in the operator's compartment.
Do not store ether cylinders in direct sunlight or at
temperatures above 39°C (102°F).
Discard cylinders in a safe place. Do not puncture or
burn cylinders.
Keep ether cylinders out of the reach of unauthorized
personnel.
Lines, Tubes and Hoses
Do not bend or strike high pressure lines. Do not install
bent or damaged lines, tubes or hoses.
Repair any loose or damaged fuel and oil lines, tubes
and hoses. Leaks can cause fires. Contact your
DOOSAN dealer for repair or replacement.
Check lines, tubes and hoses carefully. Do not use your
bare hand to check for leaks. Use a board or cardboard
to check for leaks. See Fluid Penetration in the Safety
Section for more details. Tighten all connections to the
recommended torque. Replace if any of the following
conditions are found.
z End fittings damaged or leaking.
z Outer covering chafed or cut and wire reinforcing
exposed.
z Outer covering ballooning locally.
z Evidence of kinking or crushing of the flexible part of
hose.
z Armoring embedded in the outer cover.
z End fittings displaced.
Make sure that all clamps, guards and heat shields are
installed correctly to prevent vibration, rubbing against
other parts, and excessive heat during operation.
Tire Information
Explosions of air-inflated tires have resulted from heat-
induced gas combustion inside the tires. The heat,
generated by welding or heating rim components,
external fire, or excessive use of brakes can cause
gaseous combustion.
A tire explosion is much more violent than a blowout.
The explosion can propel the tire, rim and axle
components as far as 500 m (1500 ft) or more from the
lift truck. Both the force of the explosion and the flying
debris can cause personal injury or death, and property
damage.
Do not approach a warm tire closer than the outside of
the area represented by the shaded area in the above
drawing.
Dry nitrogen(N
2
) gas is recommended for inflation of
tires. If the tires were originally inflated with air, nitrogen
is still preferred for adjusting the pressure. Nitrogen
mixes properly with air.
Nitrogen inflated tires reduce the potential of a tire
explosion, because nitrogen does not support
combustion. Also, nitrogen helps prevent oxidation and
the resulting deterioration of rubber and corrosion of rim
components.
Proper nitrogen inflation equipment and training in its
use are necessary to avoid over-inflation. A tire blowout
or rim failure can result from improper or misused
equipment.
Stand behind the tread and use a self-attaching chuck
when inflation a tire.
Servicing, changing tires and rims can be dangerous
and should be done only by trained personnel using
proper tools and procedures. If correct procedures are
not followed while servicing tires and rims, the
assemblies could burst with explosive force and cause
serious personal injury or death. Follow carefully the
specific information provided by your tire or rim servicing
personnel or dealer.
