Do Not Strike The Ground With Bucket Teeth; Avoid Hammer Work - Hitachi ZAXIS 135US-5B Operator's Manual

Do Not Strike the Ground with Bucket Teeth

d
WARNING: Forcibly striking the bucket teeth on the
ground may result in personal injury by the flying
debris. Also, this operation will shorten the service life
of each part on the front attachment.
If the bucket teeth are forcibly struck on the ground, it
shortens the service life of the front attachment parts
(especially the bucket).
When digging a hard gravel stratum, use dig up force of the
bucket. Operate the boom, arm and the bucket simultaneously
so that the bucket teeth efficiently bite into the ground.
Flying debris may result in personal injury.

Avoid Hammer Work

d
WARNING: As the bucket body has the curved surface,
hammer work or piling work is very dangerous. Doing
so may damage the bucket and front attachment.
Do not attempt to use the bucket for hammer work and pilling
work.
Doing so may damage the bucket and front attachment,
causing personal injury.
