1.3.4 Safe Operation

Before excavation operation, thoroughly check the
underground line conditions. Precisely identify
location of individual underground utility line such as
cables, gas pipeline, water pipeline etc.

Keep jobsite off-limits to all no operating person.

Make sure the condition of worksite is stable and
capable of supporting the machine.

To make it easy to escape if there is any collapse, set
the tracks at right angle to the pit with sprocket at the
rear when carrying out operation near pit.

When digging the work face under an overhang, the
overhang may collapse and fall on top of the machine.

Do not place bucket above the head of person or
operator cab. Falling objects from bucket or collision
with bucket can cause serious injury or death or
damage to machine.

When using breakout hammer or other heavy working
equipment, there is a hazard of losing its balance and
tipping over.

Do not lower, swing or stop working device all of
sudden.

Do not extend or retract boom cylinder suddenly,
There is a risk of machine tipping over due to impact
force.
1.3.5 Operation on Slopes

When operating swing or working device during
operation on slopes, there is a risk that the machine
may lose its balance or tip over. This may cause
serious injury or damage to machine. So it’s necessary
to provide a flatness area for the machine and operate
carefully.

Do not swing machine from uphill side to downhill
side, when bucket is fully loaded. This dangerous act
can cause machine to tip over.

If the machine has to be used on a slope, pile the soil
to make a platform which can keep machine as
horizontal as possible.
