WARNING
¡
¡
¡
¡
¡
If you must work beneath the raised
machine or 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.
This procedure is especially important
when working on hydraulic cylinders.
¡
¡
¡
¡
¡
If maintenance must be performed with
the engine running, always work as a
two person team with one person
sitting in the operator’s seat while the
other works on the machine.
• When performing maintenance, be
sure to keep your body and clothing
away from moving parts.
This machine uses a hydraulic cylinder to
adjust the tension of the crawler belts. Note
that it is not necessary to regularly perform
adjustments of the tension of the belt itself.
IMPORTANT: During the replacement
procedure, only start the engine when
raising and lowering the machine body.
Otherwise, always keep the engine off.
IMPORTANT: When the travel speed
switch is set to the 2nd speed side while
the engine is running, the tensioning
cylinder rods extend and the crawlers are
tightened.
