Avoid Striking With Bucket; Avoid Excavation Using Upperstructure And/Or Boom Swing Power; Use Correct Track Shoe - Hitachi ZX27U-2 Operator's Manual

AVOID STRIKING WITH BUCKET

WARNING: The bucket bottom is curved. There-
fore, hammering or piling work with the bucket is
very hazardous. In addition, damage to the
bucket and the front attachment parts may result.
Hammering or piling work with the bucket may create haz-
ardous situations. Never attempt to perform hammering or
piling work with the bucket. Damage to the bucket and the
front attachment parts may also result.
AVOID EXCAVATION USING UPPERSTRUC-
TURE AND/OR BOOM SWING POWER
Never attempt to move rocks or excavate a cliff face by
hitting the bucket using upperstructure and/or boom swing
power. Damage to the front attachment, or shortening of
the service life of the swing systems may result.

USE CORRECT TRACK SHOE

Never use rubber crawlers or wide track shoes on rough
terrain with scattered rocks, gravel or boulders. Failure to
do so may cause breakages of rubber crawlers, shoe
bending, looseness of shoe bolts, or damage to track parts
such as track links, or rollers. (Refer to the table for Types
and Applications of Track Shoes in the specification section.
Soil may easily become packed into the crawler during
travel operation on sandy ground. If the machine is driven
without removing the packed soil from the crawlers, the
rubber crawlers will be overloaded, possibly resulting in
breakage of the crawlers. Avoid causing the crawlers to
become packed with soil by removing soil as often as pos-
sible.
