not, change it into the right mode at once.
Check up the operation of the instrument and the device, and check up the operation of the bucket, the
bucket rod, the swing arm, the moving system and the steering system.
Check up if the voice, the vibration, the heating, the smell and the instrument of the machine works
normally, and check up if the engine oil or fuel oil is in leakage.
Repair the machine at once if there is any unusual thing.
Safety rules for changing the direction of the machine
Before moving, the upper structure should be
located at the proper position to make the chain
wheel located to the rear of the cab. If the chain
wheel is in front of the cab, the operating direction
is reversed (for example: going forward is changed
into going backward and the left into right). Before
moving, make sure again that there is no person or
barrier in the peripheral region.
Before moving, honk the horn to warn the person in
the area.
Only sit on the seat to operate the machine.
No one is allowed to sit on the machine besides the
operator.
Check up if the moving warner (if there is a warner)
works normally.
Ensure that the door or the window of the cab is
locked.
There is a blind area at the rear of the machine.
When the machine is turning a corner or turning
around, a signalman is needed. Especially pay
attention not to touch other machine or person.
Abide by the matters of attention above even if the
wing mirror is arranged on the machine.

Safety rules for moving
Do not exceed the maximum permissible load when using the machine in order to prevent that the
machine is unstable because of overload and avoid
the damage of the working device.
When moving on the flat ground, taking back the
working device and the bottom of the bucket must
be kept 40 to 50cm above the ground.
When moving on the rough ground, move slowly
and do not swerve to avoid roll-over. If the
working device touches the ground, the machine
may lose balance and be damaged.
When moving on the rough ground or the abrupt
slope, turn off (cancel) the automatic speed
reducing switch, if the machine is equipped with the automatic speed reducing device. If the
automatic is turned on, the rotate speed of the engine is increased, and the moving will be suddenly
accelerated.
Avoid moving on the barrier as far as possible. If
the machine has to move on the barrier, make the
working device close to the ground and move
slowly.
When moving or carrying out operation, keep a
certain safety distance from person or building to
avoid collision.
When passing the bridge or building, firstly check
up if the structure is strong enough to support the
weight of the machine. When moving on the road, consult relevant department to inspect and then
comply with their guidance.
When operating in a tunnel, under a bridge, a wire, or in other place with limited height, operate
slowly, and especially avoid the working device from touching anything.

Equipment Protection Top. ROPS or FOPS
If the machine is operated at the region with falling
stores and aggregates, the machine should be
provided with devices of the equipment protection
top, ROPS or FOPS according to the potential
dangerous situation.
(The standard driving cab of the machine is equipped
with devices of ROPS and FOPS)
ROPS: Roll Over Protection Structure
FOPS: Falling Object Protection Structure
Moving on the Slope
In order to prevent the roll-over or the sideslip of the
machine, the following requirements must be achieved:
When the machine moves on the slope, the bottom
of the bucket is 20 to 30 cm (8 to 12 in) from the
ground. In an emergency, the working device can
rapidly drop down to stop the machine.
When the machine moves upslope, the driving cab is
adjusted to the direction of the upslope. When the
machine moves on the slop downwards, the
hardness of the ground surface in front of the
machine must be examined.
When the machine moves on the abrupt slope, the
working device extends towards the front direction
to maintain the balance, and the operating
equipments keep the distance of 20 to 30 cm from
the ground, and keep at a low speed.
When the machine moves on the slop downwards,
the moving operating lever is maintained at the
middle position, and the machine moves at low
speed.
XE210C Hydraulic Excavator Operating and Maintenance Manual 30
The machine directly moves on the slop upward
and downwards, because it is very dangerous to
make a turn or traverse on the slop.
Do not make a turn and transverse on the slop. The
machine should change the position of the machine
at the flat area, and then, go up to the slope.
Because the slipping of the machine on the slop of
a small degree is dangerous, the machine should
walk on the slop at low speed.
In the engine misses when the machine is moving
on the slop, the operating lever must be shifted to
the middle position to start the engine.
