Do Not Strike The Ground With Bucket Teeth; Avoid Hammer Work - Hitachi ZAXIS 120-6 class 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 from flying
debris. It will also 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 layer, use the upwards digging
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 a 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 piling
work.
Doing so may damage the bucket and front attachment,
causing personal injury.
