MAINTENANCE
Every 50 Hours
Inspecting and Adjusting the
Crawler Tension
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.
¡ ¡
¡ ¡ ¡
The track adjuster contains highly
pressurized grease. If the tension is
adjusted without following the
prescribed procedure, the grease
discharge valve may fly off, resulting
in injury.
• Do not loosen the grease nipple.
• Loosen the grease discharge valve
slowly.
• Do not put your face, arms, legs or body
in front of the grease discharge valve.
• If no grease is expelled when grease
discharge valve is loosened, there is
a problem. Contact your nearest
service outlet for repairs. DO NOT
disassemble, as this is very
dangerous.
Inspection
1. For rubber crawlers, move the machine
so that the “M” or “
∞
” mark at the coupling
is at the top center of the crawler frame.
2. Use the operating devices to lift the body.
Operate the levers slowly.
3. Inspect the gap (A or B) between the
bottom surface of the frame at the center
of the crawler frame and the top surface
of the crawler.
The gap (A or B) should be within the
following range:
(A) Rubber crawler:
65 to 70 mm (2.6 to 2.8 in.)
(B) Steel crawler:
100 to 115 mm (3.9 to 4.5 in.)
