HYDRAULIC FLUID
Fine jets of hydraulic fluid at high pressure can penetrate the skin. Do not use your
fingers to check for hydraulic fluid leaks. Do not put your face close to suspected
leaks. Hold a piece of cardboard close to suspected leaks and then inspect the
cardboard for signs of hydraulic fluid. If hydraulic fluid penetrates your skin seek
medical help immediately.
Hot hydraulic fluid can cause severe injuries.
HYDRAULIC HOSES AND FITTINGS
Ensure all hydraulic components will withstand maximum pressure and mechanical
stresses caused by operation of the attachment. Consult your local dealer for
instructions.
FIRE HAZARD
Most hydraulic fluids are flammable and might ignite when contacting hot surface.
Avoid spilling hydraulic fluid to hot surfaces.
Working with the product on certain materials can cause sparks and hot splinters to
get loose. These can ignite flammable materials around working area.
Ensure that adequate extinguisher is available.
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 “Changing the tool” on page 50.
