Checking the pressure in the piston
accumulator
Check the gas pressure in the piston accumulator if
the hydraulic breaker does not work. Do not top up
the piston accumulator unless the gas pressure is
equal to or less than the minimum gas pressure.
Check the pressure in the piston accumulator when
the hydraulic breaker is at operating temperature
(60-70 °C).
♦
Lay down the hydraulic breaker.
Do not apply pressure to the working tool.
♦
Remove the threaded plug (A) from the filling valve
»G«.
♦
Push the hose end of the test pressure gauge (B)
into the filling valve and note the pressure.
♦
If the value measured is below the required gas
pressure add nitrogen into the piston accumulator.
The required pressure in the piston accumulator is:
with an operating temperature 60-70 °C and
without exerting pressure!
