7.1 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.
7.2 Lubrication
Lubricate the working tool shank thoroughly every two
hours using high-temperature grease such as genuine
chisel paste from your supplier. This also lubricates the
wear bushing and the retainer pin; 5-10 pumps of the
grease gun is sufficient. Stop when the grease starts to
emerge by the wear bushing or between the working tool
and the wear bushing.
WARNING
Running engine
If the carrier's engine is running when lubricating the
working tool manually there is a risk of severe accidents.
u
Always switch off the carrier's engine to avoid acci-
dents.
During lubrication, the working tool must be pressed
against the piston so that the space between piston and
the working tool does not fill with grease.
7.3 Piston accumulator
WARNING
Explosion hazard
Use of other gases than Nitrogen (N
2
) can cause an ex-
plosion.
u
Charge the accumulator with Nitrogen (N
2
) only!
As the manufacturer we offer a service box containing all
necessary tools and parts required to service the piston
accumulator. See the Spare parts list.
If the hammer's performance begins to deteriorate, we
recommend that you check the pressure in the piston ac-
cumulator.
NOTICE
The pressure must be checked with the ham-
mer at a working temperature between 60-70 ºC
(140-158 ºF).
To measure the pressure, bring down the hammer with
no pressure on the chisel. Detach the plug from the
charge valve (G) and connect the test pressure gauge.
The piston accumulator only needs to be filled if the
pressure falls below the minimum level.
Filling
1. Connect pressure relief valve (B) to gas bottle
valve (A).
2. Connect gas hose (C) to pressure relief valve (B) as
shown in figure.
3. Close pressure relief valve (B).
4. Open gas bottle valve (A).
5. Remove the plug from the charge valve (G).
6. Guide the nozzle of the hose (C) into the charge
valve.
7. Carefully open the relief valve (B).
8. Fill the piston accumulator.
9. Read the pressure on the pressure gauge (D).
10.Close the pressure relief valve when the desired
pressure has been reached.
Pull the gas hose out of the charge valve (G) and fit
the plug.
11. Close gas bottle valve (A).
