Long Arm Operation - Hitachi ZAXIS 130-6N Operator's Manual

Long Arm Operation --- If Equipped
ZX130-6N
1. The optional [3.01 m (9' 11")] long arm is only for light
works such as loam loading, sludge handling, etc.. Do
not use it for heavy works such as digging gravel. When
the arm is used for digging, apply shallow cut to the
ground to avoid tough digging, or arm damage may
result.
2. When the machine is equipped with the [3.01 m (9' 11")]
long arm, the hoe-bucket size must be limited to the
followings due to stability and strength of the machine;
* PCSA 0.45 m (0.59 yd
3
PCSA 0.50 m (0.65 yd
3
* with 700 mm (28 in) shoe
3. When the machine is equipped with the long arm,
connect the arm cylinder end to:
Pin bore A (when the machine is in operation)
Pin bore B (when the machine is transported)
IMPORTANT: Connect the arm cylinder rod end to pin
bore B only when the machine is transported. Do not
operate the digging or loading function with the arm
cylinder connected to pin bore B as the bucket may hit
the cab accidentally with this connection.
When transporting the machine, follow the procedure
shown below to convert it into the transporting posture.
(a) Position the bucket cylinder with rod retracted a little
from the fully extended position.
(b) Position the arm cylinder with rod retracted a little from
the fully extended position.
(c) Lower the boom until the arm top comes into contact
with the ground.
