Original Instructions
the shut-off valves or disconnect the quick-release
couplings, so that no hydraulic oil can flow back from
the carrier.
7.3 Cleaning
NOTICE Environmental damage due to polluted water
Hydraulic oil and chisel paste are environmentally harm-
ful and must not penetrate the ground or enter the water
table or water supplies.
u Collect the water used for cleaning if it has been con-
taminated by hydraulic oil and chisel paste.
u Dispose of the water in accordance with the applica-
ble regulations to avoid environmental hazards.
7.3.1 Preparations
Hydraulic breaker installed:
n
Place the breaker on the working tool and exert a
slight pressure.
This prevents water penetrating the percussion pis-
ton.
Hydraulic breaker not installed, working tool re-
moved:
n
Plug up all hydraulic ports.
n
Seal the aperture for the working tool with the protec-
tive cap.
7.3.2 Procedure
NOTICE Damage to the hydraulic breaker
Water can penetrate the percussion chamber via the
percussion chamber ventilation non-return valve. This
may cause the percussion piston to rust which may re-
sult in damage to the seals and the cylinder.
u Never direct the pressure cleaner jet onto the per-
cussion chamber non-return valve.
n
Use a pressure cleaner to remove dirt from the hy-
draulic breaker.
7.4 Lubrication
7.4.1 Checking the lubricant film
The lubricant film on the shaft of the working tool must
be checked during the work shift.
n
Let the hydraulic breaker hang freely from the carrier
boom.
When the working tool is hanging from the retainer bars,
the lubricant film on the shaft of the working tool be-
comes visible. There must be an even film of lubricant
on the entire shaft.
n
Increase the lubricant supply if the film of lubricant
comes away or dry spots can be seen:
–
Automatic lubrication: increase the lubricant sup-
ply via the metering screw of the ContiLube
®
II.
–
Manual lubrication: increase the lubrication inter-
val and the number of strokes from the manual
grease gun.
NOTICE Damage due to excessive lubrication
Excessive lubrication may damage the hydraulic breaker
and the carrier. The impact surface of the working tool
must be free of grease.
u Do not over-lubricate the working tool.
If the ContiLube
®
II automatic lubrication system has
been installed, a lubrication pulse is triggered whenever
the hydraulic breaker is switched on.
n
Adjust the lubricant supply to your work method.
