2) On uneven ground, travel at low speed and avoid accelerating, stopping or changing
directions abruptly.
3) When working in water, check the depth of the water, make sure that the water’s depth is
not higher than the half of the track roller. Never dip the rear end of the machine into water.

If the lubricant parts need to work in water for a long time, add enough lubricant oil until
the old oil is replaced.

Never imerge the slew bearing in water or sand, if you have to do so, contact the dealer or
technician to confirm if this is allowed.
4) Pay special attention to the balance when traveling on a slope (the maximum grade ability
is 20°, maximum lateral tipping angle is 10°). And you should note that when actual
working area conditions are poor, the machine’s
stability might be lower.

When traveling on slopes or grades, lower the
bucket to a height of 20 to 30cm. In
emergencies, lower the bucket to the ground
and stop the machine.

When traveling on slopes or grades, move
slowly in first gear (low speed).

Do not travel down slopes in reverse.

Do not change the directions or cross slopes sideways. First return to a flat surface, then
redirect the machine.
5) If the excavator can’t travel for getting into miriness, you can extend arm and place bucket
to ground to lift one side of crawler, then turn the lifted crawler to clean out the bedload. In
order to reduce the force enduring of boom and
arm, the angle between boom and arm should be
in the range of 90
°
--110
°
6) When the machine gets into wallow or passes
raceway, you can use arm and boom to help the
machine pass.
