Operating Backhoe (Super Long Front Attachment) - Hitachi ZAXIS 210LC-5N Operator's Manual

Operating Backhoe (Super Long Front
Attachment)
 This machine is designed exclusively for light excavation
work. Install the standard front attachment for general
excavation work.
 Use appropriate bucket for the work.
(Refer to the "Bucket Types and Applications" in the
Specifications section.)
 Pull the bucket toward the machine for main digging
force.
 When soil sticks to the bucket, remove it by moving the
arm and/or bucket rapidly back and forth.
 When working on solid ground, unstiffen the ground by
using standard front attachment, and then use super
front attachment for loading.
 When trenching a straight line, position the tracks parallel
to the trench. After digging to the desired depth, move
the machine as required to continue the trench.
 When operating the arm, avoid bottoming the cylinder to
prevent cylinder damage.
IMPORTANT:
 When digging at an angle, avoid striking the tracks
with the bucket teeth.
 When lowering the boom, avoid sudden stops that
may cause shock load damage to the machine.
 When digging a deep excavation, avoid striking the
boom or bucket cylinder hoses against the ground.
