Stop Operation If Breaker Hydraulic Hoses Jump
Abnormally.
Change in breaker accumulator pressure or a damaged
accumulator will cause abnormal hose jumping and may
cause breaker and/or machine damage.
Immediately stop the machine operation. Failure to do
so may result in serious failure in the hydraulic system
including pumps.
Contact your nearest Hitachi dealer.
Do Not Operate the Breaker in Water.
Doing so will cause rust and seal damage, resulting in
damage to the hydraulic system components.
Rust, dust and water may enter into the hydraulic oil
through the broken seal, damage to the hydraulic system
may result.
Do Not Use Breaker for Lifting Operation.
The machine tipping over and/or breaker damage may
result.
Do Not Operate the Breaker to the Side of the Machine.
The machine may become unstable and undercarriage
component life may shorten as a result from operating the
breaker to the side of the machine.
