Operating Tips; Select Correct Track Shoes - Hitachi Zaxis 850LC-3 Operator's Manual

OPERATING TIPS

Do not hit the track with the bucket when digging.
Whenever possible, position your machine on a level surface.
Do not use the bucket as a hammer or pile driver. Do not at-
tempt to shift rocks and break walls using swing motion.
WARNING: 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.
WARNING: Do not attempt to break ledge rock by ex-
tending the arm to maximum reach and dropping the
front of the bucket on the bucket teeth for penetra-
tion. Serious damage to the machine can result.
Once the trench is open, ledge rock can be broken by pulling
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 loosen-
ing, and may damage other undercarriage
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 tightness.
