Operation - Doosan DX140R Operation & Maintenance Manual

Using Road Liners
Prohibited Works
Do not carry out the following types of work
1. Carrying out operations and steering on crushed rock,
extremely rough hard rock, steel beams, scrap iron, or
near the edges of steel plates will cause damage to the
rubber shoes and road liners.
2. In places such as river beds where they are large numbers
of large and small boulders, the stones may get caught and
damage the rubber shoes and road liners or make the
shoes come off. If dozing operations are carried out when
the shoes are slipping, this will reduce the life of the rubber
shoes and road liners.
3. Be careful not get oil, fuel, or chemical solvent on the
rubber shoes and road liners. If such a substance should
get on the shoes, remove it immediately. Do not travel on
road surfaces where oil has collected.

OPERATION

1. When putting the machine into long-term storage (3
months or more), store the machine indoors where it is
protected from direct sunlight or rain.
2. Do not use the machine in high-temperature areas where
there is burning wood, steel plates that have been left
under the hot sun, or places where asphalt has been laid.
3. When the rubber parts of the road liner are so worn or
broken that the head of the mounting bolts are scratched,
replace the shoe immediately. If the bolts heads are
broken, the bolt cannot be removed.
4. When installing road liners, always install them to all links
on both sides. If they are installed to only one part of the
links, their durability will be greatly reduced.
