Do not extend any hydraulic cylinder to the end.
Reserve an allowance during operations.
When the machine body is lowered and the
bucket arm cylinder is completely extended, do
not support the machine body by bucket working
device. Otherwise, the load will be concentrated
on the bucket arm cylinder to probably damage
the bucket arm cylinder.
No Digging by Pulling or Hammering Bucket
Do not operate by the down force of machine.
This will shorten the life of bucket working
device. Dig by hydraulic force.
Using additional tension onto the machine will shorten the life of machine. During digging, use
the hydraulic force of cylinders by shallow depth
and large travel.
Digging of Bed Rock
For hard bed rocks, it’s preferable to break the
rock into small pieces by breaking hammer
before digging. It can prevent the damages of
machine and thus can be more economic.
