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
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:
–
increase the lubrication interval 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.
n
Adjust the lubricant supply to your work method.
