10.5.11 Checking pressure in piston accumulator and refilling if required

For checking the piston accumulator of the hydraulic
breaker you need

nitrogen filling de

ice

pressure gauge

4", 025 bar, test class

nitrogen cylinder

adapter, country specific

These items should be on hand at all times to allow
the following checking and maintenance work to be
performed.

CHECKING

f the performance of the hydraulic breaker starts to

drop,  the  gas  pressure  in  the  breaker’s  piston  accu
mulator  should  be  checked.  The  piston  accumulator
does  not  need  to  be  refilled  until  the  gas  pressure
has  dropped  to  the  minimum  le

el or below.

Note

The pressure should be checked at an operating
temperature of

0°C to 70°C.

ay the hydraulic breaker flat to check the pressure.

Do not apply contact pressure to the working tool.

Unscrew the plug from filling

»G«

and connect

up the pressure gauge.

Read off the pressure.

The re

uired pressure in the piston accumulator is as

follows
