BACKHOE TELESCOPIC ARM
The option of extending the backhoe arm makes it possible to perform operations outside of the normal backhoe radius. This
would be for grading, ditch cleaning and using optional attachments.
DESCRIPTION AND CONTROL
This structure is designed with an external hollow arm (1) within the
inner arm (2) supporting the equipment slides on a “V” shaped series of
guides. This arm is extended or retracted hydraulically.
The system controlling the telescopic arm movement is controlled by a
pedal (3) positioned in the operators compartment. When the pedal is
rocked forward, the arm is extended, when the pedal is rocked backward
the arm is retracted.
Remark
When the arm is extended, the breakout force of the backhoe
is reduced when lifting loads.
“OPERATING THE BACKHOE” on page 2-38.
SAFETY LOCKS
When traveling or operating the front end loader, the safety clip (4)must
be inserted into the telescopic arm and pined in place with the pin(5).
When using a hammer, compactor, or similar attachments contact your
Komatsu Dealer prior to using any attachment with the telescopic arm.
To install the safety lock, retract the arm fully, remove the pin and clip
from its holding place and insert it into the holes cut in the arm boss.
