Operating Tips; Select Correct Track Shoes - Hitachi ZAXIS 70 Operator's Manual

OPERATING TIPS

Do not hit the track with the bucket when digging.
Whenever possible, position your machine on a level sur-
face.
Do not use the bucket as a hammer or pile driver. Do not
attempt to shift rocks and break walls using swing motion.
IMPORTANT: To avoid damaging cylinders, do not
strike the ground with the bucket nor
use the bucket for tamping with the
bucket cylinder fully extended (the
bucket completely curled under).
Adjust the length and depth of each cut to produce a full
bucket with every pass.
Full loads on every pass is more productive than a faster
cycle with a partially filled bucket.
Full load should be the first objective, followed by speed, to
increase productivity.
IMPORTANT: Do not attempt to break ledge rock by
extending the arm to maximum reach
and dropping the front of the bucket on
the bucket teeth for penetration. Serious
damage to the machine can result.
Once the trench is open, ledge rock can be broken by pull-
ing the bucket up under the layers. The top layers are
pulled out first, with one or two layers being lifted at a time.
Do not side load the bucket. For example, do not swing the
bucket to level material or do not strike objects from the
side with the bucket.

SELECT CORRECT TRACK SHOES

IMPORTANT: Using wide track shoes on rough ground
may result in shoe bending and/or
loosening, and may damage other un-
dercarriage components.
Never use wide track shoes on rough ground such as
rocks, sand or gravel. Wide track shoes are designed for
soft ground.
Track shoe bolts should be checked periodically for tight-
ness.
