Long Arm Operation --- If Equipped
ZX135US-5B
1. The optional [3.01 m] 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]
long arm, the hoe-bucket size must be limited to the
followings due to stability and strength of the machine;
* PCSA 0.45 m
3
PCSA 0.50 m

* with 700 mm 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
