Cleaning
NOTICE Environmental damage due to polluted
water
Hydraulic oil and chisel paste are environmentally
harmful and must not penetrate the ground or enter
the water table or water supplies.
► Collect the water used for cleaning if it has been
contaminated by hydraulic oil and chisel paste.
► Dispose of the water in accordance with the
applicable regulations to avoid environmental
hazards.
Preparations
Hydraulic breaker installed:
♦
Place the breaker on the working tool and exert a
slight pressure.
This prevents water penetrating the percussion
piston.
Hydraulic breaker not installed, working tool
removed:
♦
Plug up all hydraulic ports.
♦
Seal the aperture for the working tool with the
protective cap.
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 result in damage to the seals and the cylinder.
► Never direct the pressure cleaner jet onto the
percussion chamber non-return valve.
♦
Use a pressure cleaner to remove dirt from the
hydraulic breaker.
Lubrication
Checking the lubricant film
The lubricant film on the shaft of the working tool
must be checked during the work shift.
♦
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 becomes visible. There must be an even film of
lubricant on the entire shaft.
♦
Increase the lubricant supply if the film of lubricant
comes away or dry spots can be seen:
● Automatic lubrication:
increase the lubricant supply via the metering
screw of the ContiLube
®
II.
● Manual lubrication:
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.
► 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.
♦
Adjust the lubricant supply to your work method.
