(when operator sits on the seat). The four movements
of handle can make the excavator move as follows.
e ——Make the superstructure slew widdershins.
f ——Make the superstructure slew clockwise.

Composite movement of excavator
1) When the machine slews, you can operate the
composite movement of boom and bucket.
2) It can operate as follows: bucket digs while arm
is flexing; arm digs while lowering boom, etc.
3) Besides the co-operation between right and left
handle, pull either of the handles to any diagonal
orientation (45° direction), can achieve the
adjacent two composite movements.
Slewing platform brake
Release slewing control handle, return it to neutral position, it will bring sufficient brake power
to brake platform. While reverse handle operation can bring more brake torque.
