CRAWLER EXTENSION/RETRACTION
This machine is equipped with the spanner
mechanism (crawler extension / retraction
mechanism). T
ake the following procedure.
1. Jack up the main unit.
Set the blade to the rear and jack up the main unit
with the working device and blade cylinder till the
crawler is off from the ground to extend or retract
the crawler easily
.
2. Lever selection
Set the engine speed at medium or higher. Push
and hold the button “spanner”. Move the
blade-spanner lever forward or backward.
• Crawler extension : Push the lever forward.
• Crawler retraction : Pull the lever backward.
Extend or retract the crawler on a level ground
without an obstacle.
Extension or retraction is possible without
jacking up the main unit.
If there is an obstacle on the ground beside the
crawler, the resistance is larger and extension
or retraction is sometimes impossible.
