• The ECSS does not operate while the boom angle is 25
deg. or larger from the level.
• If the travel speed exceeds 5 km/h while the gear speed is
2nd to 4th, ECSS operates automatically.If the travel
speed decreases below 4 km/h, ECSS stops operation au-
tomatically.

tioned at a low height, you may feel the poor damper
(ECSS) effect. This is not an abnormality.
