Travel brake
Release travel pedal or travel handle, it will return to natural position automatically, the machine stops

to place the working device on minimum radius position, the
bucket will be about 0.5m to the ground.
(2) Lift dozer blade to its zenith.
(3) Choose plane road to travel as much as possible. It
should travel straight when traveling or turning, and also turn
large bend, avoid turing blind bend. When turn in one point at
confined area, it should operate gently.
(4) When travel at badlands or uneven carpolite road, it
should reduce engine rev and travel at about 1.5km/h to reduce
the vibration.
(5) Avoid back traveling to prevent crawler parts damaging
prematurely.
(6)
If the excavator can’t travel for getting into miriness,
you can extend arm and place bucket to ground (as figure) 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

(As figure 3.4.7)
(7) When the machine gets into wallow or passing
raceway, you can use arm and boom to help the machine
passing (As figure 3.4.8)
(8) Extend arm when travel on slope, lower bucket
to 0.5m to ground (As figure 3.4.9)Travel downgrade
