MAINTENANCE
replacing the rubber crawlerS
Warning
• If you must work beneath the raised
machine or working equipment, always
use wood blocks, jack-stands or other
rigid and stable supports. Never get
under the machine or working
equipment if they are not sufficiently
supported.
• If maintenance must be performed with
the engine running, always work as a
two person team communicating each
other.
· One person must sit in the operator’s
seat so that he/she can immediately
stop the engine when necessary. He/
she must take care not to touch the
lever or pedal unless necessary.
· The one who performs maintenance
must make sure to keep his/her body
or clothing away from the moving part
of the machine.
IMPORTANT: When replacing the crawler
belts, replace the right and left belts at
the same time.
IMPORTANT: When the travel speed
button is set to the 2nd speed side while
the engine is running, the tensioning
cylinder rods extend and the crawler belt
tension is increased. Keep the engine at
the 1st speed when replacing. Do not set
to the 2nd unless for increasing tension.
Note: This machine uses a hydraulic cylinder
to adjust the tension of the crawler belts. It is
not necessary to regularly perform
adjustments of the crawler belt tension.
