Operation—Operating The Machine
OUT1739,00001EE –19–16JUN06–1/1
Cold Weather Warm-Up
1. Run engine at 1/2 speed for 5 minutes. Do not run
at fast or slow idle.
CAUTION: Prevent possible injury from
unexpected machine movement. Clear the
area of all persons before running your
machine through the warm-up procedure. If
machine is inside a building, warm the travel
circuit first and move the machine to a clear
area outside. Cold oil will cause machine
functions to respond slowly.
NOTE: In extremely cold conditions, an extended
warm-up period will be necessary. Under such
conditions, the radiator and oil cooler should
be covered to maintain correct operating
temperature.
Avoid sudden operation of all functions until
the engine and hydraulic oil are at operating
temperature.
2. Exercise travel and swing functions slowly, initially
moving only short distances.
3. Operate boom, arm, and bucket functions by
moving cylinders a short distance each direction for
the first time.
4. Continue cycling cylinders by increasing the travel
each cycle until full stroke is obtained.
5. Swing upperstructure so boom is perpendicular to
tracks.
CAUTION: Prevent possible injury from
machine sliding backwards. Keep angle
between boom and arm 90—110
°
.
6. Keeping the angle between boom and arm 90—
110
°
, fully actuate bucket close function (cylinder
extend) and lower bucket to raise track off ground.
IMPORTANT: Holding function actuated for more
than 10 seconds can cause damage
from hot spots in the control valve.
7. While rotating raised track in forward direction,
actuate bucket curl function (cylinder extend) for 10
seconds and release for 5 seconds for a period of
2-1/2 minutes.
8. Repeat procedure with track rotating in reverse
direction.
9. Lower machine to ground.
10. Repeat steps 5—9 on opposite track.
11. Operate all hydraulic functions to distribute warm
oil in all cylinders, motors, and lines.
12. If hydraulic functions still move slowly, repeat
steps 6 and 7.
