Tracks on both sides stuck
When the tracks on both sides get stuck and slip, lay logs,
wooden blocks, etc. according to the preceding procedure.
Stick the bucket into the front ground, pull in the arm as in dig-
ging operation, and set the travel lever to FORWARD position
to drive the machine out.
RECOMMENDED APPLICATIONS
In addition to the following, it is possible to further increase the range of applications by using various attach-
ments.
DIGGING WORK
BACKHOE WORK
It is suitable for excavating areas that are lower than the machine.
When the condition of the machine is as shown in the figure
(angle between bucket cylinder and link, and between arm cyl-
inder and arm is 90 °), the maximum excavation force is ob-
tained from the pushing force of each cylinder.
When excavating, you can optimize your working efficiency by
using this angle effectively.
The range for excavating with the arm is from a 45 ° angle
away from the machine to a 30 ° angle towards the machine.
There may be some differences depending on the excavation
depth, but try to stay within the above range rather than operat-
ing the cylinder to the end of its stroke.
SHOVEL WORK
This is suitable for excavating at a position higher than the machine.
Shovel work is performed by attaching the bucket in the re-
verse direction.
