Safety 455
HYDRAULIC PRESSURE
Hydraulic fluid at system pressure can injure you. Before disconnecting or
connecting hydraulic hoses, stop the carrier engine, operate the controls to release
pressure trapped in the hoses and wait ten (10) minutes. During the operation, keep
people away from the hydraulic hoses.
There might be pressurized oil trapped inside the product even if it is disconnected
from the carrier. Be aware of possible blank firing while greasing or removing and
installing hammer tools. See “Removal of tool” on page 44.
PRESSURE ACCUMULATORS
The safety label on or near the accumulator is shown below.
"HIGH PRESSURE HAZARD
Improper handling of pressurized accumulator will cause death or severe injury.
Read workshop manual before disassembly.

) only."
The hammer incorporates one or two pressure accumulators, depending on the
model. The accumulators are pressurized even when there is no hydraulic pressure
to the hammer. Attempting to dismantle the accumulators without first releasing the
pressure can cause injury or death. Do not try to dismantle pressure accumulators,
contact your local dealer first.

equipment is in good condition. Make sure that the lifting equipment complies with
all local regulations and is suitable for the job. Make sure that the lifting equipment
